How to determine which iPhone. IPhone A1387: review, description of technical characteristics

Hello everyone, today I will tell you about how you can use your mobile Apple gadget - iPad or iPhone. In fact, this is very simple to do - you will need a little perseverance and a few minutes, even seconds, of time. There may be many reasons to find out the model of your iPad or iPhone, but the most common reason is to check your Apple mobile gadget for originality.

I will consider one reliable way to find out the model - look at the relevant information in the gadget settings. This is done as follows:

Method 2

If, of course, an even easier way to find out the model of your mobile gadget is to look at it on the back cover of the gadget. But I don’t really like this method, because you can write anything on the lid. Turn over your mobile Apple gadget - iPad or iPhone, find very small text at the bottom of the cover. Look carefully at this text and find the model item, there you will find out the model of your mobile gadget.
This is how you can easily and without unnecessary movements find out the model of your mobile gadget from Apple - iPad or iPhone.

Additionally

As you could use this method, you can find out not only information about the model of your device, but also a lot of other useful information, for example: the number of photos stored on the device, the number of music tracks, programs. I also recommend paying attention to the “Serial number” item.

Apple smartphones and tablets have one feature: the exact model name is not indicated on their case. Instead, it just says iPhone or iPad. It looks beautiful and stylish, but in some cases it is inconvenient, since it is difficult to determine which model is in front of you. Now we will look at several ways to determine the iPhone model in this situation.

Determining iPhone model by model number

The easiest and most reliable way to find out what iPhone model you have is to look at the model number. Knowing the model number, you can easily determine the model name. This can be done using the table on this page, or you can simply enter the model number into any search engine and examine the results.

The model number is always indicated at the bottom of the back cover of the iPhone and is represented as “Model A1429”, where “A1429” is actually the model number. The picture below shows what it looks like on an iPhone 6s.

Below is a table with a list of all currently existing iPhone models and the numbers that correspond to them.

Determining iPhone model by serial number

You can also find out your iPhone model by its serial number. Unlike iPads, the serial number is not indicated on the iPhone case, so to find it you need to open Settings and go to the “General - About this device” section.

Once you have your serial number, you can go to Apple's Service and Support Eligibility Check page to find the model that matches that serial number. To do this, go to, enter the serial number, verification code and click “Continue”.

If you do everything correctly, a page will load where you can find out the model of your iPhone.

Determining your iPhone model using iTunes

Another way to find out your iPhone model is iTunes. To use this method, connect your iPhone to your computer and launch iTunes. An icon of the connected device will appear in the upper left corner of the iTunes window; click it to go to the iPhone settings.

As a result, a page will appear on which you can find out the iPhone model, the capacity of its built-in memory, serial number and other similar information.

Apple iPhone 4S review. Initially, everyone was waiting for this smartphone for a very long time, then it suddenly appeared on store shelves and aroused admiration, then brought some disappointment for Apple fans, but in the end it still turned out to be successful and very competitive. This smartphone remains one of the most popular today, just a day after pre-order opened on the Apple website at iPhone 4S 1,000,000 orders were received (which is 400,000 more than the previous version), and by the time it appeared on the shelves, the entire circulation had already been sold out. No other manufacturer has ever managed to achieve this, and it’s unlikely that anyone will succeed in the near future. Apple knows how to surprise, it feels like they have some kind of special magic. So let's take a closer look smartphone Apple iPhone 4S and his review .

Equipment
In the box you will find:
Telephone
Stereo headset with remote control
USB cable
Network adapter
“Paper clip” for opening the SIM card tray
Documentation

Design and Construction
Apple decided not to change the still current design of the iPhone 4, so in appearance these phones are practically indistinguishable.
The phone is sold in two colors - black and white. Both look chic, and most likely are divided according to the following criteria - white for girls, black for guys. The front panel houses a 3.7" Retina display covered with protective glass. Below the display there is a round button to exit to the menu. Above the display there is a speaker, a light sensor and a front camera.

As in Apple Iphone 4 in this smartphone the number of mechanical buttons is kept to a minimum.

On the right edge there is a tray for a SIM card in .

On the left edge there is a mute button and two volume control buttons.

On the top edge there is a power/lock button and a jack for a 3.5" wired headset.

At the bottom there are two speakers, a microphone and a charging and data synchronization connector.

On the back cover you can find the model number - A1387 and the inscriptions: developed by Apple in California, made in China.

Dimensions of the iPhone 4S are 115.2 x 58.6 x 9.3 mm. Weight - 140 grams. As you can see, the dimensions are identical to its predecessor. Overall, the dimensions are chosen well: the smartphone is not too wide, not too thin, fits perfectly in the hand, just like the iPhone 4.

Display
Apple used the display from the previous model: this is the same 3.7-inch Retina display with an excellent resolution of 960×640 for its diagonal and an IPS matrix. In terms of image quality and color rendition, this type of display, although it does not reach Super AMOLED displays, which are installed on Samsung Galaxy S II, but overall it does its job well and is not technologically outdated. The display is covered with protective glass Gorilla Glass.

Platform and speed
The Apple Iphone 4S platform has changed dramatically compared to the Iphone 4. Inside the iPhone 4S is now roughly the same engine as the iPad 2: a dual-core Apple A5 processor with a PowerVR SGX 543MP2 graphics coprocessor. Thanks to this, according to the developers' measurements, the 4S should be seven times faster than its predecessor. And of course, iOS 5 will “fly” on this platform.

The speed of the iPhone, as before, does not lie in the number of cores or RAM (there is the same amount left, 512 MB), but in software optimization, due to which it is possible to achieve operating speeds unprecedented even for devices with more powerful specifications.

However, even in tests, the Apple iPhone 4S shows excellent results. In the future, the A5 plans to develop games with super graphics, in particular, Infinity Blade 2, which will first be exclusive to the iPhone 4S.

The main question that interests users is how much faster iOS 5 runs on the iPhone 4S than on other company products. Opinions are divided here: some notice the brakes, while others are completely satisfied with the behavior of the new OS on their iPhone 4. It is impossible to say unequivocally that iOS 5 does not work with sufficient speed on other devices other than the iPad 2 and iPhone 4S.

The Apple Iphone 4 and Apple Iphone 4S are not much different in software. After the release of iOS5, almost all the functions of the iPhone 4S appeared in the iPhone 4. The main distinguishing feature of the 4S is the Siri assistant.

I compared the speed of iPhone 4 and iPhone 4s on iOS5 and found the following:
The Safari browser launches at the same speed on them, but on the iPhone 4S pages load faster, and this is very noticeable in comparison. Google Maps also launches almost identically, but getting directions works faster on the iPhone 4S, like redrawing the map. The difference is more visible in the game Infinity Blade: levels load faster on the 4S, there are practically no slowdowns. The speed increase is definite, but it will be noticed mainly by Infinity Blade players. On the iPhone 4S, the camera starts up faster, photos are stored faster, and autofocus works faster. Although the camera in the iPhone is already one of the fastest on the market. In the iPhone 4, switching between photo and video takes place in a couple of seconds, in the iPhone 4S in a second or even less.

It’s interesting that here we have to talk not about seconds, but about fractions of a second; in fact, this is the instant launch of most programs. You get very used to this, then you expect the same from your tablet, laptop and other equipment.

Connection
The Apple iPhone 4 wasn't perfect as a phone. The light sensor worked in it for days, thanks to which you could press a button on the display with your head during a conversation, sometimes the call simply ended, you had to wear a bumper so as not to touch the antenna with your hand.

In the Apple iPhone 4S, the manufacturer has lost all of the above problems. The proximity sensor here works perfectly, in a month of use there was not a single unwanted button press during a conversation, nor a call being dropped. The volume of the speaker remained at the same level, the interlocutors can hear you perfectly, the reception level does not change, no matter how you hold the device without a case. As for the reception quality, it seemed to me a little better than the iPhone 4.

It should be noted that there is a problem when the device operates on versions with micro SIM cards from some companies - the devices consistently lost the network. The same devices worked without problems with cut MTS SIM cards. Some users solved the problem by updating to iOS 5.1, others changed their micro SIM cards to regular ones.

Energy saving and battery life
A strong argument in favor of the iPhone 4 or 4S is the battery life, while owners of “Android” devices are forced to charge the devices once a day, and sometimes more often; with the iPhone 4 and 4S you can go for two days, of course, if you don’t overload it with programs , multimedia and communications.

The iPhone 4S has a claimed battery life of eight (3G) or fourteen hours (2G) of talk time; in fact, after the device is fully charged, the indicator shows thirty percent charge after almost two days. Where you have already charged several times, the iPhone 4S continues to work and work.

Battery The Apple iPhone 4S is built-in and is not designed for independent replacement. This causes some inconvenience if the device gets into liquid. The first tip for this is to turn off the phone and remove the battery. But you will not be able to remove the battery without special tools. In addition, do not forget about the global conspiracy theory, since the battery in the phone is always connected, theoretically the intelligence services can reveal your location at any time.

Camera
The Apple iPhone 4S has an eight-megapixel camera with autofocus and the ability to independently focus on the desired object. With the new processor, the camera works much faster. The optics have not changed compared to the iPhone 4. I would like to note that even the iPhone 4 from the point of view of photographs was and remains an excellent device. The camera menu has not changed, you can turn the flash on, off or set it to auto mode. You can quickly activate HDR mode, quickly use the front camera to create a self-portrait and proceed to viewing photos

The quality of the pictures is nothing short of impressive. The device shoots well both outdoors and indoors, both macro objects and landscapes and portraits. As with all mobile cameras, shooting in the dark is not its strong point. The iPhone 4S can be used for shooting text and cheat sheets. Focusing occurs almost instantly.

The device now shoots HD video at 1080p resolution, but for video it clearly lacks a stabilizer. The image quality is good, it can be used for shooting YouTube videos or a home album.

Programs
Let's look at some standard programs installed on the phone. Basically nothing has changed compared to the iPhone 4. Same old familiar apps. Writing SMS is just as convenient and fast. Although after SGS2 the keyboard seems too small.

It’s also not difficult to figure out the calendar; everything here is intuitive, even without explanation.

Photos are sorted in the same way as in the iPhone 4. Viewing photos is also very convenient, the phone responds perfectly to the touch of a finger, so there should be no problems viewing photos. Multi-touch works great, with which you can quickly zoom in on pictures.

The watch can display time from multiple time zones.

Everyone will find the Utility Folder useful. It contains probably the three most used programs. These are contacts (address book), voice recorder and calculator. The compass will probably not be used that often. All these programs are convenient and understandable.

Dictaphone.

Calculator.

Siri

The personal assistant Siri, developed by Apple, is a feature and exclusive of this device. As practice shows, before the release of the iPhone 4S, few people used voice search, dialing or voice prompts on their phone. First of all, this happened because the implementation of these points on phones was not convenient.

Apple, as always, has tried to bring together these various functions and hone them almost to perfection. Siri works great even in noisy environments, although it may take longer to recognize, but it will hear you anyway. By the way, this could be a new impetus for the Bluetooth headset market. Siri is not a toy; for example, filling out a calendar using Siri is long and tedious. But you can easily tell your phone the time and place of the meeting by voice - it’s convenient. Unfortunately, Siri does not yet support Russian and Ukrainian languages, but if everything is fine with English, then you can work with Siri without any problems. iPhone 4S is currently the ideal device for people with visual impairments. Considering how easy it is to call, compose a message, check the weather, etc. here.

It seems that Siri has become the main feature of this device for Jobs. Here you will not only get the opportunity to communicate with the machine - we have seen this before, but communication with the machine will be on a completely new level. For example, you said something wrong, you were informed that they could not understand the command, you apologize out of inertia, Siri says that there is no need to apologize. You set the alarm, Siri asks you to confirm the time, you say OK, and in response you hear an analogue of our “As you say.”

conclusions

In terms of sales and profits, Apple has clearly achieved success with this device. Perhaps for some it did not live up to expectations and brought very few innovations in comparison with the Iphone 4, but overall the device turned out to be successful. At the beginning of sales, the gray device in Russia cost more than 2 times more than in the USA and Europe - at first they were sold here for $1,500. Now the prices for the device have dropped; now a gray 16 GB device can be bought for about $800. The price is higher than that of analogues, but not significantly.

iPhone 4 owners are constantly asking whether it is worth upgrading to an iPhone 4S? The answer is simple, if you have extra money, then you should change it, because it is not yet known when the iPhone 5 will appear, especially since the difference in price between the devices at the moment is not at all great.

What are the advantages does this device have compared to the iPhone 4?
The design and materials are excellent, although there are some minor issues with the build quality.
Increased speed and operating time, better camera, respectively, improved quality of photos and videos. The sound quality in the player has not changed; in this phone, as in its predecessor, it is one of the best on the market. The quality of the telephone part has improved - the iPhone 4S is now close to ideal. Well, I can’t help but mention Siri - this is one of the main bonuses for the buyer of the iPhone 4S.

The disadvantages include the lack of a new fresh design, there are no new wallpapers, sounds and other applications besides Siri specifically for the iPhone 4S. Apple also did not present any new accessories for the device.

As a result, Apple It turned out to be an excellent device, but it seems that for the company this is a transitional model for testing Siri and ICloud. By analogy with FaceTime, when it was first tested on the iPhone 4 and iPod touch, then FaceTime came to laptops and tablets. This suggests that the main changes will affect the design, display, replace the processor, install more memory, and a different camera. And then it will be a truly different phone. This concludes our review of the iPhone 4S.

Different mobile companies support different communication standards. This refers to types of communication that exist within one generation, but are incompatible with each other. This situation is due to different connection conditions in a particular state, as well as national customs and traditions. It happens that companies with different standards operate in the same country.
Like other mobile device manufacturers, Apple Corporation takes these features into account when designing smartphones. Each new version of an Apple device comes with a specific communication module. But the consumer is guaranteed to receive a device that will catch mobile networks. In this sense, the company's work is impeccable.
But what if the user decides to buy a fake smartphone made in China? How can I find out where it originates from, and for which country the communication module that is built into it is intended?

The iPhone 5S version is one of the most popular phone models from Apple, enjoying constant popularity among consumers. Therefore, there is very great interest in this smartphone on the black market. Over the past year, buyers have most often purchased this gadget model because of its functionality and reasonable price-quality ratio.
If the user purchased such a device from an unreliable or dubious seller, you need to check which network it belongs to. And the most reliable way to do this is to punch the iPhone by serial number. This method is also suitable for those who buy a smartphone not in a regular store, but online, when there is no way to hold the device in their hands, insert a SIM card, check the connection, etc.
The following points must be remembered:
IPhone 5S A1457 works in GSM networks.
IPhone 5S A1533 – also supports GSM communications.
IPhone 4 GSM usually has the serial number A1332.
iPhone 5 with number A1429 supports both GSM and SDMA.
Above were examples of the most common iPhone models and the correspondence of their serial numbers to a specific type of connection. Some of them, such as the iPhone 5, support 5 communication modules. But this is the exception rather than the rule.
The buyer can find out the model number by reading it on the back panel of the device.
It should be noted that in Russia, iPhones are sold, as a rule, with GSM communication modules. But if the user decides to purchase a device abroad, for example, in the USA (nowadays this is easy to do, for example, through eBay), such a device will most likely have a CDMA module installed.

What is the difference between standards: CDMA in Russia

So what is this standard, and why are such devices practically not represented on the mobile gadget market in our country?
Many iPhone users know that devices sold in America are 20-30%, or even 2 times cheaper than in Russia. This is partly true. You can buy such a device, for example, an iPhone 4 model, in America for $200-250. But the fact is that the American smartphone will not work on the GSM standard that is familiar to Russia, but on CDMA. The latter, alas, does not work in our country.
Simply put, due to the fact that there are no CDMA Global networks in Russia, the mobile communication system is based on a GSM module.

Surely, readers have a question: why are the prices for gadgets with a CDMA module so low? This is explained by the fact that when purchasing a smartphone in America, the consumer immediately enters into a service agreement with a specific telecom operator. Moreover, the subscriber will not be able to subsequently choose another communications service provider, but will have to remain loyal to the initially chosen company. This approach is very beneficial for the telecom operator, because he receives a regular customer for many years. But the buyer of an iPhone gains no less benefit: by agreeing to these terms of the contract, he buys the gadget at a price of 50% of its real cost. Thus, both parties benefit – both the company and the client.
But how does the above scheme work in practice? What if the user finds a more profitable telecom operator in the future. Will he really not be able to cancel the contract? It is important to know here that a number of versions of iPhones are designed for the CDMA module. They come with special SIM cards, and in some models (for example, iPhone four), there is no SIM card at all. Or rather, it is present, but in a non-standard form.
As noted above, in our country you cannot find devices with a CDMA module. There is no point in selling them in Russia, because... The user will not be able to make a call from such an iPhone. However, on the black market, a fraudulent seller can sell such a device to an inexperienced buyer under the guise of being purchased on eBay or another online store.
How not to fall for the tricks of scammers and understand that this is a device running on GSM, i.e. suitable for use in Russia? This is not difficult to do. You need to check the SIM card tray, which must be present inside the device.

What to do if you come across a CDMA device

If, nevertheless, you in a hurry or out of ignorance purchased a device based on a CDMA communication module, what should you do? In fact, nothing bad happened. The device is not defective, it may be original, which means it is of high quality. All functions specific to the device model are working. The only thing is that the device will not be able to perform one of its main functions - making and receiving calls.
The user can use such a gadget as a player. It will have such features as connecting to the network via WiFi, downloading applications from the AppStore, browsing the World Wide Web, etc. Therefore, if you were deceived by a dishonest seller, you can keep your iPhone as a good digital player. You can also try to sell it at the price of an iPod, because... in essence, such a device would be nothing more than an iPod.
Regarding the possibility of Internet navigation in such a device, a reservation should be made that the user will have to purchase a router for the device.

Why do you need a mobile version of the site? In the complex modern world, more and more advanced technologies are being created. Over the past decade, we have witnessed amazing growth in the development of mobile technology. Almost every week we see new gadgets appearing on the global market. Smartphones and tablets seem to be outpacing laptops and computers. More and more people use mobile devices in their lives. Entertainment, getting information or even running a business, all this can be done easily. Despite this obvious growth in mobile technology, there are still some webmasters who are too stubborn to convert their websites into mobile websites.

In this article, let's start discussing a very hot topic that seems to irritate webmasters a lot, why we should convert an existing website into a mobile website. The first obvious reason is that most websites that have not been converted to mobile sites will not display correctly on mobile devices. You can easily lose repeat visitors and sales in this situation. For example, if a mobile user is looking for something to buy on your website, but finds out that your site structure is loading too slowly, he will certainly leave to look for the required item on other mobile websites.

Mobile sites are the best

Why does a website need a mobile version? Moreover, mobile websites also rank higher in search engines. It is clear that in classic search engine optimization (SEO), things have already gone too far. But with mobile SEO, it's just the beginning! The largest search engine in the world, Google will, in fact, first display results that are optimized for mobile users. Here's how you can get the means to achieve your goals and beat the competition!

With mobile websites, you can be there for your visitors all the time. Most mobile phone users are on the move and search for information on the go. If you display a phone number on your mobile site, your visitor can call you directly from their mobile device. For example, if you are a restaurant owner, this hungry user appears to be passing through your site. He can call the restaurant directly from his mobile phone and inquire about the food, location or any other information he needs! That's what the mobile version of the site is for.

Now you can see how great it can be to convert your existing website into a website for mobile devices (phones, smartphones, phablets, tablets)!

Before you finish, consider some numbers. The world population is 6.7 billion people. Of these, five billion are mobile users. If that's not enough to convince you to convert your site to a mobile website version, here's another fact; an incredible 80 percent of these mobile users access the Internet using mobile devices every day! That's four billion users every day. It is undoubtedly clear that the mobile industry is moving very quickly. Over the next two years, the mobile Internet will overtake the natural website industry. So, friends, don't forget to take care of your mobile website today!

Electronics manufacturer Cooler Master has a range of hardware products such as keyboards, power supplies, headsets, computer (PC) cases, mice and, of course, coolers. Each of its products has been specifically designed based on community feedback. Including hybrid keyboards. Cooler Master even had a Kickstarter project for an analog keyboard with pressure-sensitive keys called the ContolPad. With that said, let's take a closer look at what can make the new Cooler Master SK621 keyboard special for the user.

The first thing that is noticeable during the review is the ability to conveniently pair the wireless keyboard with three different devices. Connecting your device is as simple as holding the function button and Z, X or C. This feature makes it very easy to switch from using your phone to your computer. Turning on the Cooler Master SK621 keyboard is also easy. Either connect it via a USB Type-C cable, or on the left side activate the very simple switch for wireless mode.

You can map a wide variety of colors (shades) to any key, customize lighting modes, or customize macros using the Cooler Master software.

How does a wireless keyboard work?

When using the SK621 for the first time, it is recommended to connect to your computer via USB Type-C and install the Cooler Master Portal. This will allow you to control the different lighting effects and settings of the wireless keyboard. It is possible to create preset profiles, which makes it easier to switch between profiles when using elements. You can also adjust the lighting effects using the controls, but the portal mentioned above is more user-friendly. The wireless keyboard setup is very easy to use and has many combinations. There are options - adjusting the speed, direction and brightness of the keyboard backlight effects.

Macros can also be programmed. It’s also worth adding that all functions such as RGB lighting, macros and controls are also available when using the SK621 via a Bluetooth connection. The wireless keyboard's battery life is also impressive. It may take a couple of full business days before the light turns red, indicating that the battery is low. Charging the SK621 wireless keyboard is also easy. Just connect your keyboard via USB Type-C. The keyboard can still be used as a wired keyboard as long as the cable charges the keyboard's battery.

The keyboard's body is crafted from polished aluminum, making it lightweight, durable, and premium looking. There's also a nice sleek aluminum edge accent that adds a touch of elegance. The keys are made of plastic and don't have much texture.

Low-profile Cherry MX keys are quiet enough for office use. The key switches are incredibly sensitive and using the Cooler Master SK621 Wireless Keyboard takes some practice. This is because the keys register key presses to within a millimeter or less.

The SK621 hybrid keyboard is designed to be compact and quite portable. A nice addition is the velvet bag. It's definitely made for gaming thanks to its Cherry MX keys, but it's easy to use for work.

The Cooler Master SK621 does everything it's designed to do. However, the keys are great for gaming but are too sensitive for typing. Plastic keys are also prone to oil stains on your fingers, so eating while gaming can be difficult. Perhaps if the keys had some kind of oil-resistant coating or more texture, the oil marks wouldn't be as pronounced.

ETH Zurich has unveiled details of "Concrete Choreography", an installation that recently opened in Riom, Switzerland. The innovative installation features the first robotically constructed 3D printed concrete stage, consisting of formless columns 3D printed to full height in 2.5 hours. The process is expected to significantly improve the efficiency of concrete structures while achieving the fabrication of complex material components and construction robots.

In Riom, Switzerland, the Origen festival features nine 2.7-meter-high columns. Each column is 3D printed concrete. The new columns were individually designed using custom software and manufactured using a concrete printer, a new automated concrete 3D printing process developed by the ETH Zurich team with support from NCCR DFAB.

3D concrete printing like this

MSc Digital Fabrication and Architecture students explore the unique capabilities of multi-layer extrusion printing, demonstrating the potential of computer-aided design and digital fabrication for the future of concrete construction. Perhaps in the construction industry, this process will become more environmentally friendly in the future if they develop new eco-friendly concrete for 3D printing.

Video review of 3D concrete printing: Concrete choreography.

This is how easy and fast 3D concrete printing works.

3D printing of houses and buildings made of concrete is a prospect for construction.

Hollow concrete structures are printed for the strategic use of materials, resulting in a more sustainable approach to specific architecture. Additionally, the calculated material structure and surface textures are an example of the versatility and significant aesthetic potential of 3D concrete printing when used in large-scale structures.

The new review will be about printing on a 3D printer with metal.

It is worth noting that there is technology to carry out 3D printing with metal. This is also a promising direction for construction, but for this, other materials are used (for example, powder), programs and other types of printers (which we will talk about soon).

What color is your mobile phone? Is it black, red, white, gold or blue? Most likely, the back of your phone has some kind of solid color option that you will find in a coloring book for beginners. It has taken too long for most phone manufacturers to realize that phone colors actually matter to consumers, and it is only recently that they have started giving mobile phones not just a rarely used color, but fancy shades like coral red or canary green.

It's no surprise that most people don't mind hiding the backs of their phones behind an opaque plastic case. In cases, the user can choose a suitable color for the phone case to give the mobile a little personality. But China's new Honor 20 Pro and Honor 20 series phones are the world's first smartphones with 3D dynamic holographic design, and their reflective appearance could become a new industry standard.

Color 3D holography for the phone case.

In order for the phone body to achieve a shimmering optical illusion, the manufacturer Honor designed its Honor 20 model with a deep layer containing millions of shimmering microscopic prisms, and on top of this a so-called 3D curved glass layer is placed. The combination of these technologies causes the light to "play and dance" on the back of the phone as the user turns it in different directions.

Two colors for the Honor 20 phone can be found under these dynamic layers, Midnight Black and Sapphire Blue. Unlike the newfangled phrases for some phone colors, Honor mobile has color gradients for phones that actually evoke the effect of a shimmering night sky or a shimmering jewel.

While the color options sound exciting, you can go even further with the Chinese Honor 20 Pro phone. This upgraded model features the signature "Triple 3D Mesh" containing three layers. Instead of just painting the back of the phone itself, this time a layer of body color sits between the outer 3D layer and the inner depth layer. According to the phone maker, this makes color shifting effects much more dynamic.

The Honor 20 Pro mobile phone is actively sold in two colors such as Phantom Black and Phantom Blue. Although the names of these phone colors are not so metaphorical, do not think that their rear panels are less dynamic.

Honor's obsession with choosing the right colors may seem overly dramatic, but in the UK, for example, a survey of hundreds of Brits found that forty-nine percent of them consider color when choosing a phone to buy.

Why is a phone with a changing color scheme being sold?

What is a phone for? Choosing a mobile phone, as Honor designer Jun-Soo Kim puts it, is “Extending human life.” Essentially, Honor is saying that customer identity cannot be captured in one unchanging color.

The history of the creation of Honor color phones.

The Honor 20 demonstrates the natural evolution of the company's experiments with dynamic color in phone design (irridescent colors). The Honor 8 model started the trend of a 2.5D multi-layer back wall, which creates a 3D lattice effect. Then the Honor 9 version turned into a phone with a curved 3D glass, echoes of which can already be found in the Honor 20 model. Well, last year, the Honor 10 model was equipped with an Aurora rear glass that reflected colors from all sides.

What is the screen like on an Honor phone?

Honor's design innovations don't stop at the color of the phone's body. It's worth paying attention to the placement of the Honor 20's camera. Instead of trimming the screen to make room for the "selfie" camera. The phone maker has cut a 4.5mm hole in the top left corner of the screen, thereby leaving more screen space for the user's needs.

Camera with artificial intelligence or AI camera in your phone.

According to the description of the phone, it is worth noting that on the back of the device, the Honor 20 AI camera has four lenses and is located so as to leave more space for a battery with more memory. But most importantly, the result is a 48-megapixel camera that uses the Kirin 980 AI microchip to take DSLR-quality photos and enhance photos.

Summary of Honor phone color.

Bottom line, phone descriptions, technical compatibility and cutting-edge hardware innovations are what usually attract attention to Chinese Honor phones. But in this case, the technology is almost overshadowed by the uniquely colored body design, which may make some users reluctant to go back to simple 2D phone body colors in the future.

Rumors continue to arise regarding the launch of the Google Pixel 4 mobile phone. A new set of information or predictions comes from a leaked image (3D rendering of colored cases) on the Internet, which is believed to be of the Google Pixel 4. It is not uncommon for users to spy Because of the theme of new products, such images are overlooked. Meanwhile, for some analysts, the new picture helps make a few assumptions about more than just the color of the phone.

A new unofficial image of the Google Pixel 4 is sparking rumors about color options for the mobile phone's body.

While another image of the phone body itself doesn't seem to show more than what was previously discussed online, the model seen in the background of the photo raises eyebrows due to its color. That mobile phone has a shade of purple that the Pixel model didn't have before.

Whatever leak about the phone's colors is true or false, it's safe to assume that the new Google Pixel 4 will definitely have an additional color this year. What's even more interesting is that in the image, the physical buttons on the sides of the phones contrast with the color of the body. You can see white, blue and yellow buttons which give the phone a fun look.

For some strange reason, all the images and leaks seen so far have only shown the rear panel of the Google Pixel 4 smartphone. As reported by various sources, Google allegedly shared a render of the phone, and there was also a part where the square camera bump was featured. The dual camera unit was visible.

The leaked photos being discussed, including the image along with the cases, show the back panel in different colors and the camera module. What do you think is the best phone color?

About the technical characteristics of Google Pixel 4:

Obviously, the idea of ​​a fingerprint scanner is not leaving fans alone. Some people want the phone to either have Face ID to unlock the phone, or an in-display fingerprint scanner, or both.

Some other aspects and specifications, such as the dimensions of the phones and the overall thickness being 8.2 millimeters higher compared to the 7.9 mm seen in the Google Pixel 3 and Pixel 3 XL, can be taken as close to reality.

There is speculation that the Google Pixel 4 and Pixel 4 XL versions of the phone may look more like the "Apple iPhone 11" variant that is slated to launch in a couple of months. When, exactly? Technology company Google has yet to announce an official release date for the Pixel 4, but various sources are hinting at a new phone launching later in the year.

Have you ever wondered why you need the latest model phone? We'll tell you more about this soon, so stay tuned for news about new smartphones from Google.

The robot set a world record for solving a Rubik's Cube. This robot was developed by Massachusetts Institute of Technology (MIT) students Jared Di Carlo and Ben Katz in a student laboratory. For comparison, the fastest human record is held by Australian Felix Zemdegs, who solved the Rubik's Cube in just 4.22 seconds in 2018. By the way, the original size Rubik's Cube has 43 quintillion possible combinations for one solution. Watch the video of the record-breaking robot below.

Many people have a special place in their hearts for the Rubik's Cube. This is a good workout for the intellect. Many people loved or still love to play with this ingenious toy, and over the years there have been many competitions, challenges and variations to solve the Rubik's Cube.

New record for solving a Rubik's Cube 3x3x3.

Engineers and hobbyists have been using robots to solve Rubik's Cubes for years. 10 seconds used to be considered a quick assembly, but by today's digital age standards, that's a time that makes you smile.

It was only a matter of time before engineers and roboticists began to tackle the challenge of creating a new robot. Back in 2016, the robot set a new record for solving a Rubik's Cube in 0.637 seconds. But for some enthusiasts, that time wasn't fast enough.

Just recently, two MIT students, Jared Di Carlo (a third-year electrical engineering and computer science student) and Ben Katz (a mechanical engineering graduate student), thought they could build a faster robot that could solve a 3D combination puzzle.

They watched videos of previous robots, and noticed that the robots' motors were not the fastest that could be used to solve the problem. So they thought they could do better with better engines and controls.

How a robot solves a Rubik's Cube

Students installed an electronically controlled motor that powers each face of the Rubik's Cube. Using a pair of web cameras pointed at the cube, special software determines the initial state of each side of the cube (which colors are on which side of the cube at a given time). Then, based on the information received, using existing software for solving the Rubik's Cube, the robot solves the puzzles using an algorithm.

What is the result of the work? Their robot solved a Rubik's Cube in 0.38 seconds! It is safe to say that no person is physically capable of breaking the record for this speed. We can add another achievement to the list of robots surpassing humans.

There is a man who holds the fastest world record for hand assembly, his name is Felix Zemdegs. He was able to solve the Rubik's Cube in 4.22 seconds. The skills and talents that robots are replacing are vast and varied, to say the least. Not to mention that robots can still surprise. Next is a video demonstration of the robot; it’s better not to blink while watching.

Video review of assembling a Rubik's Cube in 0.38 seconds:

Just like that, hardware hackers Ben Katz and Jared Di Carlo broke the previous record for robotically solving a Rubik's Cube. Their robot solved the puzzle 40 percent faster than the previous record.

Details about the record-breaking robot

The robotic device is assembled from motors from the Kollmorgen ServoDisc U9 series, PlayStation Eye cameras (for scanning the cube) and, of course, a Rubik's Cube was needed. According to the robot's creators, "The entire software process takes about 45 milliseconds. Most of the time is spent waiting for the webcam driver and determining the colors on the sides of the Rubik's Cube."

Facebook Inc. Artificial Intelligence Research Group. introduced a new robotics platform called PyRobot. This platform (framework) was developed jointly with researchers from Carnegie Mellon University. PyRobot aims to help AI researchers and students integrate deep learning models built using the PyTorch platform (a machine learning library for the Python programming language) with the robots they create. The basic idea is that they can create their robots more easily by using artificial intelligence skills such as natural language processing.

Facebook said it wants to promote long-term robotics research to help develop embedded artificial intelligence systems that can learn more efficiently by interacting with the physical world.

What is PyRobot today

PyRobot is a lightweight, high-level interface that provides hardware-independent APIs for robotic manipulation and navigation. The PyRobot repository also contains a low-level stack for LoCoBot, a low-cost mobile manipulator hardware platform (robot assembly toolkit). Now artificial intelligence and machine learning are becoming more accessible to those new to robotics.

Research supervisor Abinav Gupta and Saurabh Gupta, as a research fellow at Facebook, explained in a blog post that: PyRobot is a lightweight, high-level interface on top of the robot's operating system. It provides a consistent set of hardware-independent middle-level APIs (application programming interfaces) for controlling a variety of robots. PyRobot abstracts away the details of low-level controllers and interprocess communication, so machine learning specialists and others can simply focus on building high-level AI (artificial intelligence) robotics applications.

Facebook's source also says PyRobot has dozens of potential applications, such as helping researchers share data and set benchmarks and build on each other's work. The company solicited proposals from the broader AI research community on how to democratize robotics using LoCoBot and PyRobot, which are hardware specifications and tools for building low-cost robots.

PyRobot works by using APIs to abstract the functions that robots need to use. Perform tasks such as kinematics, path planning, position, speed and torque control for joints, and visual simultaneous localization and mapping. PyRobot comes with a number of pre-trained deep learning models that allow robots to navigate, grasp objects, and more.

This means developers can program their robots using just a few lines of Python code, Facebook says.

Facebook researchers also say that: The cost of hardware and the complexity of specialized software limit the scope of robotics research. With lower barriers to entry, researchers can, for example, build multiple robots that collect data and learn in parallel. Providing a common platform for various equipment. PyRobot will lead to the development of benchmarks in robotics, similar to other areas in AI, and will quantify the pace of progress in AI robotics.

Like Amazon's RoboMaker, PyRobot runs as an interface on top of the robot operating system (ROS), extending the infrastructure. In May, technology company Microsoft released a set of robotics tools with a limited preview, and last year integrated the ROS platform into Windows 10.

The famous analyst and author of Apple smartphone forecasts, Ming-Chi Kuo, can certainly be the most reliable source of leaks and information about Apple products. And today he released a new research report, obtained by Mac Rumors, where he mentions the future of the iPhone and when we can expect Apple to finally switch to 5G (fifth generation mobile communications) smartphones.

Back when Apple was still planning to use Intel modems in its iPhones, there were rumors that the "iPhone 2020" phone model would be the first to receive 5G support. However, the Apple company has since switched from its modem supplier to Qualcomm. For which they had to settle a long patent dispute with an American chip manufacturer, pay at least 4.5 billion dollars and not use Intel modems. Intel may even have shut down its 5G plans after this news.

Ming-Chi Kuo also said that all three iPhone models in 2020 will come in multiple colors and feature an OLED screen, as opposed to the LCD screen on the current iPhone XR. However, we'll probably still get an iPhone XR upgrade with an LCD display this year, so if an OLED screen in a mobile is too much of a deal for you, maybe wait a year.

5G iPhone competitors:

Currently our best Android competitors are the following 5G phones:

1) Xiaomi Mi Mix 3 5G (128 GB memory, 6 GB RAM and battery with fast charging);

2) OPPO Reno 5G (innovative design, affordable price, powerful camera);

3) LG V50 ThinQ (screen 1440 by 3120 pixels, memory expansion up to 1 TB, 4000 mAh battery);

4) OnePlus 7 Pro 5G (frameless AMOLED screen has no notches or holes);

5) ZTE Axon 10 Pro 5G (48 megapixel camera, Snapdragon 855 chip).

New articles will contain a unique video review of 5G phones with prices.

Global sales of 5G phones.

Global deliveries to stores of mobile phones supporting 5G technology (this is the fifth generation of fast mobile communications) may be higher than market analysts' expectations. It's worth noting that some mobile market observers believe such shipments are likely to reach 150 to 200 million units, or more than a dozen percent of global 5G phone shipments next year.

Billions of people are expected to be able to make payments using cryptocurrency from social media giant Facebook through their mobile apps. The social network Facebook plans to officially launch a new cryptocurrency project, Libra, in 2020. Libra is a new type of digital money that is intended for billions of people using mobile applications and the social network.

That a new digital wallet would be created that would allow Facebook app users to store and exchange cryptocurrency. Facebook is creating a new subsidiary, Calibra.

Why is Facebook betting on a cryptocurrency called Libra? Perhaps the lofty goal of the latest development is to go beyond social networks.

Digital wallets for storing, sending and spending Libra cryptocurrency will be connected to messaging platforms.

Initially, the cryptocurrency will be available in the Facebook Messenger / WhatsApp application, and of course in separate applications for iOS or Android.

Facebook said in a press release that: “Initially, Calibra will make it easy and instant to send Libra at a low cost to virtually anyone with a smartphone.”

It also says that: “Over time, additional services will be offered to businesses and people, such as buying a cup of coffee with a scanned code, paying a bill with the touch of a button, traveling on public transport without having to carry cash.”

Security of the Facebook cryptocurrency wallet.

To improve the security of the new cryptocurrency, it will use similar verification and fraud protection features that are already used by credit cards and banks. Facebook's cryptocurrency service will have user support. And in case someone else gains access to the user account, compensation for lost assets is promised.

Cryptocurrency coins will be stored by users in a digital wallet. But the world of cryptocurrency itself is not always stable! Time will tell if Facebook's own digital money will help people save money by sending and spending it as easily as sending text messages.

The cryptocurrency will be managed by the founding members: Facebook, more than two dozen different organizations and a separate Swiss foundation.

Why Libra?

What does the word Libra mean?

Former PayPal executive David Marcus, who heads the Facebook project, said something like this: "The choice of the name Libra (Libra) was inspired by several reasons, namely the French word for Liberty, the Roman measurement of weight, the astrological sign of justice."

What would you like to know about Facebook's Libra cryptocurrency?

Technology giant Apple will release iPhone 11 this coming September. If all sorts of rumors turn out to be true, then the multimedia phone could have the same design as the last two generations of the phone. Regarding the final design of the iPhone 11, we are ready to accept what Apple designers come up with. But, we can't stop imagining what could be if technology allowed us to create any design for the iPhone 11. And that's exactly what some very talented designers are doing. This time around, there's a beautiful concept for the iPhone 11 that ditches all the buttons in favor of an immersive curved phone screen.

While it may be a good looking phone, there is absolutely no chance of the concept becoming a reality. In addition, protecting such a phone with a case seems impossible, since by covering the screen space the case will take away some of its basic functions. Imagine that if such a phone were accidentally dropped on the ground, the cost of repairing a curved screen would be higher for the user than with a classic screen version.

We hope the new iPhone 11 will have a bright screen under the sun.

The 2019 iPhone 11 lineup is expected to feature three models, just like last year. There will probably be two OLED phones and one with an LCD screen. The iPhone 11 and 11 Max models may have a variety of OLED screens, and also have screen sizes of 5.8 and 6.5 inches, respectively. Perhaps the iPhone 11R model will be equipped with an LCD display to reduce the price to a minimum.

It is also expected that the new versions of the iPhone 11 and 11 Max will have a triple camera configuration, while the iPhone 11R version is expected to be equipped with a dual camera. Essentially, this means that all three mobile phones could come with an additional camera on the back.

The front of the iPhone 11 lineup is expected to remain the same and there will be no difference in the size of the notch. However, recent reports claim that there may be improved face identification that will be able to authenticate a user at some extreme angles.

Video review of the iPhone 11 concept with an innovative, curved screen on the side:

According to the creator of this video, the new bezel-less iPhone 11 could have the following specifications:

6.4-inch full-screen display;
- Hidden front 13MP camera;
- Four cameras, 8K @ 120 FPS;
- New Apple operating system, iOS 13;
- Apple A13 Bionic mobile chip (up to eight times faster than the A12 Bionic chip).
