What is the resolution of the iPad 4. iPad lineup. Recovery via RM

In the small town of San Jose, California, with a population of just under a million people, a presentation took place on October 23, 2012 Apple, where new products were presented to the world mobile devices, among which new tablets appeared: and iPad 4. Of course, the new Mini lineup has gotten the most attention, which is why some didn't even notice the arrival of the larger 4th generation iPad.

On the official Apple website, the fourth generation tablet was called “ iPad with Retina display", Californians for some reason avoid the simple and sonorous name iPad 4. A similar situation was with its predecessor, which was called " The New iPad" Along with the release of the fourth generation Apple tablet, the third iPad dropped out of the Apple Store, and sales of the iPad 2 continue. Let's not delve into the specifics of the work of Apple marketers and move directly to the review of the fourth iPad.

Characteristics of iPad 4 and differences from iPad 3
The first thing you pay attention to when getting acquainted with the new product is the hardware. Appearance, of course, also matters a lot, but in the case of Apple tablets, the design differences are minor. And if we talk about the difference between the third and fourth iPad, then there is simply none, not counting the new Lightning connector, which was first used in. The new interface is nothing more than a replacement for the usual 30-pin connector for charging the device, connecting accessories and synchronizing with a PC. The latest iPod Touch and iPad Mini also received it.

The author of the book “Insanely Simple” about the success story of Apple, Ken Segall, wrote in one of his articles that sending the 30-pin connector into retirement was necessary not only for brand owners, but also for consumers. In his opinion, it is not advisable to sell devices with an outdated interface on the eve of the Christmas holidays. An adapter from a 30-pin connector to the new Lightning is available in the Apple store for $30.

Now let's take a look at key differences between iPad 3 and iPad 4 (for ease of understanding we will call them that). The fourth iPad received a more powerful dual-core Apple A6X processor, whose frequency is 1.4 GHz. The graphics accelerator, in turn, contains 4 cores and has a performance of 76 GFLOPS.

The next difference, as you probably already guessed, is the use of a new Lightning connector. The 4G module has also undergone modernization - it has received expanded support for LTE, which will increase the speed of Internet access via a cellular network. Unfortunately, networks of this kind are not available everywhere; in the countries of Eastern Europe, for example, they are known only by hearsay. For some reason they did not equip the 4th generation of “large” tablets with new ones, leaving support for standard cards. Unlike its predecessor, the new 4th generation iPad comes with pre-installed firmware Apple iOS 6.0.1.

Speaking about the new Apple A6X processor, I would like to note that it has introduced hardware image processing technology - this will speed up the operation of the built-in camera (its resolution is 5 megapixels) and improve the quality of pictures. The front iSight camera in the fourth iPad has a resolution of 1.2 MP – it can now shoot 720p video.

The Wi-Fi module now supports 2.4 GHz and 5 GHz frequencies, which will improve compatibility with new router models.

In other respects, the iPad 4 literally copies its predecessor: it has the same Retina display with a resolution of 2048 x 1536 pixels, a glass and aluminum body with a black or white frame around the display, the built-in storage capacity is 16, 32 and 64Gb. There is still no option to expand the internal memory. The dimensions and weight of the 4th iPad (652 g) exactly match the parameters of the 3rd generation tablet: 241.2 x 185.7 x 9.4 mm.

Competitors
Witty observers call the latest updates to Apple's lines not revolutionary, but evolutionary. It’s hard to disagree with them, since Californians’ new products are only gradually being improved and are perceived quite calmly.

iPad 4 was no exception. It has an excellent display, high-quality performance and powerful hardware that far exceeds the needs of a typical consumer. However, it does not contain anything revolutionary; moreover, its main competitor is Google company, recently introduced its Nexus 10 tablet, the display resolution of which is 2560 x 1600 pixels, which is slightly higher than that of the iPad 3 and 4.

iPad 4 prices
Regarding the cost, it remained at the level of the third iPad: $499 for the 16GB Wi-Fi version, $599 for the 32 GB Wi-Fi version and $699 for the 64 GB Wi-Fi version. Prices for models with 4G LTE are as follows: $629, $729 and $829 for 16, 32 and 64GB versions, respectively.

Having studied all the iPad models and their characteristics, you can understand how the technologies for creating Tablet PCs have developed and progressed from 2010 to the present day.

After all, these famous gadgets, both a few years ago and now, are equipped with the most modern parts. And you can see development from them.

Moreover, some analysts suggest that iPads will eventually be the first to displace a significant part of desktop computers from the market, surpassing them, if not in power, then at least in mobility and ease of use.

iPad 1

The first iPad went on sale in 2010 and became a truly revolutionary gadget that received many technologies that other tablet PCs did not have at that time - an IPS display and a powerful gigahertz Apple A4 processor.

High operating speed, a screen with a diagonal of almost 10 inches and a capacious 6667 mAh battery made the iPad 1 popular.

However, it was still just an experimental model, with a number of shortcomings and shortcomings.

Among the disadvantages of the device were the relatively short operation time on a single charge - even such a battery was not enough for the large display and the resource-intensive iOS operating system.

In addition, the iPad was quite thick by the standards of other tablets and did not come with a camera, which is why it could not be used for video chatting.

But its body has rounded edges and stylish volume control buttons on the right side.

The developers’ original solution was the button for switching lock modes and screen orientation, which lights up green when turned on.

Another impressive characteristic is the tablet’s built-in memory, the maximum capacity of which was 64 GB.

Although the rather modest RAM parameters did not allow installing more modern versions on the tablet.

Technical specifications:

• Screen size: 9.7 inches;
• resolution: 768 x 1024;
• processor: single-core, 1000 MHz;
• cameras: none;
• memory capacity: 256 MB RAM and from 16 to 64 GB built-in;
• Battery capacity: 6667 mAh.

iPad 2

The next generation of iPad, which appeared in 2011, was more advanced and had many fewer shortcomings.

First of all, this concerned the amount of RAM that had increased to 512 MB - quite enough to run modern applications and install new operating systems.

In addition, the model received two cameras at once - the main one with 0.69 megapixels. and frontal with resolution (640 x 480), gyroscope and dual-core processor.

Most other characteristics, except for a more powerful processor, remained at the same level. Visually, the gadget was distinguished by the edging of the Home button, which matched the color of the body.

Tablet parameters:

• screen: 1536x2048 pixels, 7.9 inches;
• chipset: 2 cores, 1300 MHz;
• cameras: 5 and 1.2 megapixels;
• memory: RAM – 1 GB, ROM – 16, 64 and 128 GB;
• Battery capacity: 6471 mAh.

Another plus is the most affordable price in the entire history of the series. Basic version models can be purchased for as little as $329.

At the same time, decent capabilities and quite affordable prices allow the gadgets to compete well with the top versions of other manufacturers.

And not only among amateurs Apple products, but also among users who prefer high performance and modern technologies.

The Apple iPad 4 tablet is an Apple gadget released in 2012. The main “update” of the new product compared to its predecessor was the Lightning connector, enhanced hardware, support for LTE frequencies and an improved rear camera sensor. The 4th generation gadget is still used by fans of the brand as multimedia device for reading books, playing games, watching movies and surfing the Internet.

iOS

From the start of sales apple tablet iPad 4 ran iOS version 6.0.1. From that moment on, the gadget was updated up to firmware version 10.3.3, released on July 19, 2017. This is the latest of the iOS 10 series. The gadget did not receive support for the 11th generation OS.

The most stable versions of iOS on which the gadget worked were the final versions of the 7th and 8th generations. Interfaces 9 and 10 provide the owner of the Apple iPad 4 tablet with a significantly better user experience. This is due to the increased functionality of the operating system and the increased number of supported applications.
On the other hand, the device's performance is not enough or just barely enough to run smoothly and without interruptions on the final version of iOS 10.3.3. The device works much slower than on previous generations of the OS. The best version of iOS for the Apple iPad 4 tablet, according to users, is 8.4.1.

Characteristics

The Apple iPad 4 tablet was a premium solution in its time. With the best characteristics at that time.

Processor and memory, case materials

The hardware basis of the gadget is the Apple A6X processor. Thanks to its high performance and potential, the company supported the tablet until 2017, despite the release date of November 2, 2012. The RAM is only 1 GB, but this is quite enough for iOS, especially for the versions available on the tablet.

The gadget lies confidently in your hands. Dimensions: 241.2 x 185.7 x 9 mm, weighs a little more than 600 grams. The body is made of metal, monolithic.

Cellular versions have a black plastic seam to ensure proper operation of the antennas.

Battery, built-in storage and wireless networks.

The Apple iPad 4 tablet has good battery life thanks to a Li-Pol battery with a capacity of 11650 mAh. The battery can withstand 10 hours of video viewing on just one charge! The tablet can be found in three modifications. One has wireless support Wi-Fi networks, Bluetooth 4.0, the rest all work with 4G networks. The difference between the last two is the supported LTE frequencies. Built-in memory: 16 GB, 32 GB, 64 GB, 128 GB.

Cameras

The Apple iPad 4 tablet has rear and front cameras. On the back there is a sensor with a resolution of 5 megapixels, on the front - 1.2 megapixels. Capable of recording video in FHD and HD respectively. It takes pretty mediocre photos, but for video calls it’s just right.

Screen

The Apple iPad 4 uses a high-quality 9.7-inch Retina display with a resolution of 2048x1536 px, demonstrating fairly high image detail. The ppi indicator is 264. It is pleasant to watch movies on the gadget, it is convenient to read books and get acquainted with various multimedia content.

The entire front panel is covered with scratch-resistant glass. The surface is mirror-smooth, the Apple iPad 4 tablet is easy to use. The finger glides without any complaints.
To replace it yourself, you will need a heating device, several plastic picks, a pair of screwdrivers, Double-sided tape and glue. Of course, changing the glass or display on an iPad yourself is quite dangerous, so we recommend turning to professionals.

If you still decide, here is the procedure:

1. Warm up the glass of the iPad 4 with a hairdryer around the perimeter, the approximate temperature threshold is 70 degrees.

2. It is important not to damage the Home button or the front camera sensor. Try to detach the glass from the gadget. It is advisable to pry from the upper right corner.

3. Having peeled off the glass, the user will see the display underneath.

4. Remove the matrix, simultaneously unscrewing the 4 bolts that secure it, disconnecting the cable. We perform a similar operation with the touchscreen - disconnect it.

5. This is where the difficulties ended. Install the new display module, tighten the 4 screws, and do not forget to connect the cable.

6. Connect the touchscreen harness and start gluing the front glass (new), insert the Home button into it.
When changing the matrix, you will have to buy new glass. It is almost impossible to remove the old one without leaving marks or damage on it. However, the most difficult stages in the entire replacement are 2-3.

Touchscreen

The Apple iPad 4 tablet has a fairly sensitive sensor that supports 10 simultaneous touches. We have already figured out how to replace it.

How to speed up Apple iPad 4

Apple iPad 4 tablet shows best performance on iOS 8th generation. If the device is using the latest operating system from Apple - 10.3.3, you can try to rollback (see Restoring Apple iPad 4). Or try to optimize the performance of iOS 10.
Here are some tips:
Disable icon shaking - parallax effect. Completely unnecessary animation that slows down the tablet. Settings app - General - Accessibility - Reduce Motion.
Disable transparency. This is done along the following path: “Settings” – “Basic” – “Universal Access” – “Increase Contrast” – “Decrease Transparency”.
Disable self-updating of games and applications in the background: “Settings” – “General” – “Content Update”.
Of course, clean the internal memory of the Apple iPad 4 tablet from debris, unnecessary applications.
Reboot your device regularly.
These few tips will allow you to use latest iOS for the Apple iPad 4 tablet with great comfort.

Wi-Fi Cellular or Wi-Fi what is the difference

As mentioned earlier, the Apple iPad 4 tablet existed in three versions: the Apple iPad 4 Wi-Fi tablet and two Apple iPad 4 + 4G tablets. The 4G prefix was often replaced with the word “Cellular”. Thus, Wi-Fi Cellular - a device that supports 3G, 4G networks, has a slot for a SIM card. A gadget with a Wi-Fi attachment relies solely on connecting to the network through this wireless module.
The external difference of the Celluar version is the presence of a plastic insert in the upper rear part of the device body.

Price policy

At the start of sales, the Apple iPad 4 tablet was a luxury only for certain people, because the cost of the Wi-Fi version with a minimum amount of built-in memory started at 19,990 rubles, of course, at the old exchange rate.
Now Apple iPad 4 is sold on the used market in the price range from 6 to 10 thousand rubles, depending on the condition of the device and its configuration. Reviews from real owners are extremely positive. Some people bought a gadget back in 2012. It still serves them today.

iPad 2 (2011)

In March 2011, Apple introduced the second generation iPad, which has become one of the most widely used tablets on the market (this model was sold for four years and supports all iOS updates available today).

iPad 2 was distinguished by a thinner body with rounded edges and the presence of two cameras - front and rear with a resolution of 0.3 and 0.7 MP, respectively. In addition to the light sensor and accelerometer available in the first generation iPad, the device was equipped with a gyroscope.

The hardware component of the tablet has received significant improvements. Along with the iPad 2, the dual-core Apple A5 processor with a frequency of 1.0 GHz debuted, and the volume random access memory has been increased to 512 MB. The graphics were handled by the PowerVR SGX543MP2 chip.

In addition, the iPad 2 was available in two colors - black and white, and the difference in color solutions was only in the color of the frame on the front panel (the body still remained silver). iPad 2 was available in 16, 32 and 64 GB versions with or without a 3G module.

In 2012, with the release of the iPad 3, a second revision of the iPad 2 appeared on the market with more capacious battery and the Apple A5 processor, made using a more efficient 32 nm process technology.

iPad 3, iPad 4 and iPad mini (2012)

iPad 3, or The New iPad, was visually practically no different from the second generation iPad. You can distinguish the iPad 3 from its predecessor only by the number located on the back cover and the enlarged rear camera eye with a new 5 MP matrix.

Technically, the iPad 3 stood out primarily for its new Retina display with a resolution of 2048 x 1536, which provides a pixel density of 264 ppi. Installing such a display required expanding the battery, and therefore the weight of the device and its thickness increased slightly.

The basis of the iPad 3 was the Apple A5X processor with a frequency of 1.0 GHz. The tablet also received 1 GB of RAM. The storage capacity and available colors have not changed.

The first one was presented together with the iPad 4 iPad model mini. In technical terms, this device was an almost exact copy of the iPad 2. From the iPad 4, the tablet received a cellular communication module, camera resolution and a Lightning connector.

Diagonal iPad screen mini was 7.9”, which with a resolution of 1024 x 768 provided a pixel density of 163 ppi.

To create a more compact body, the side frames of the display were trimmed. The body itself was completely painted in the color of the frame and had less flat edges back cover. The volume buttons on the iPad mini have become separate keys, and the SIM card tray has moved to the right side of the case.

The iPad mini was initially available in black and white. In October 2013, a 16 GB version in gray color appeared.

iPad Pro 9.7" and iPad 5g

A few months after the release of the “large” iPad Pro, the company presented its professional device in a more familiar form factor. New tablet distinguished not only by smaller dimensions: iPad Pro 9.7” became the company’s first device with the so-called True Tone display, which allows you to adjust on the fly color temperature display depending on the environment.

Against this background, the release of the “consumer” iPad 5g a year later went unnoticed: without any high-profile announcements, Apple launched an updated and cheaper version of the iPad for ordinary users who did not need the features of the Pro version.

The device turned out to be interesting: having a thicker body that is comparable to the Air 1 (the only difference is the absence of a physical silent mode switch), the device received an accelerated Apple A9 processor and a better camera compared to the Air 2.

iPad Pro 2 and iPad Pro 10.5”

In June 2017, along with the announcement of the iPad Pro in the new 10.5" form factor, the update also affected the classic iPad Pro in 12.9" diagonal.

The “large” iPad Pro received support for True Tone technology and increased frequency display at 120 Hz, as well as an updated A10X Fusion processor, which increased the performance of the device. Otherwise, the iPad Pro 2 copied the 2015 model.

The new “frameless” iPad Pro with a 10.5” diagonal turned out to be more interesting: while maintaining the dimensions of the 9.7” model, the device received a larger display, and the “heart” of the new tablet was the same chip as on the older model. It was with iPad Pro 10.5 that the company introduced ProMotion technology, thanks to which the display frequency can vary over a wide range, allowing it to display up to 120 frames per second.

iPad 6g

In March 2018, the iPad line received another minor update. Keeping design and others iPad specifications 5g, the new iPad received a modern Apple A10 SoC processor with a frequency of 2.3 GHz and a new graphics subsystem, which made it possible to speed up the overall performance of the chip by about one and a half times.
