Tablet pc lenovo tab 2 a10 70l. Information about the type of speakers and audio technologies supported by the device
Lenovo in 2015 introduced its ten-inch tablet with 2 GB random access memory, it is called TAB 2 A10-70L. Since the company is known for producing a wide range of devices, ranging from smartphones to laptops, it feels more than good in the tablet market. You can find a large selection of high-quality Lenovo devices from budget to premium. Today's copy at the time of release belonged to the middle price category. Let's take a closer look at what kind of "fruit" it is, producing Lenovo review Tab 2 A10 70L 16 Gb.

Equipment
The tablet is sold in a small cardboard box, which shows the device itself and describes its technical characteristics. The diameter of the box is slightly larger than the tablet itself. The package is standard and does not contain additional accessories. So, in the box, in addition to the device itself, you can find a power supply, a cable for charging and connecting to a PC, and all the necessary documentation, including instructions and a warranty card, as well as a list of equipment on a separate sheet. The set is standard, as they say, nothing more.
Design
The tablet is made in an ordinary design without any features - everything is simple and concise. But this does not mean that he looks bad, quite the contrary. The main body material is matte plastic, it is quite durable. The device comes in two colors, namely white and dark blue.
On the front panel you can see the display with protective glass, above it on the side face there is a camera and the company logo. It is by the location of the camera and the logo that it becomes clear that the landscape orientation of the tablet is the only correct one. And besides, a ten-inch device in a different position is not very convenient to work with.
At the top end there is a headset jack, there is nothing else there. On the left you can find the volume and power buttons, they feel great, have a good response and do not creak. Next to the buttons, there is a micro-USB input for connecting charging or synchronizing the gadget with a computer. On the same side there is a hidden slot for a memory card and a SIM card, it is hidden under a special plug. On the right side there are no connectors, and on the bottom there is only a microphone.
Back panel Lenovo TAB 2 A10-70L meets another company logo in the middle. The camera module is located at the top center, on its sides there are two speakers and holes for them.
The tablet turned out to be large enough for a resolution of 10.1 inches. It could come out a little smaller if the bezels around the display would be thinner, but there is a plus in this - the device is more comfortable to hold and there is no risk of false clicks. The case creaks a little, and the back panel is made of soft plastic and flexes when you press it, but only by a millimeter. However, it is worth considering that this adds flexural strength to the device. For those who prefer a hard back panel, you can buy a case with hard walls.
The tablet weighs just over 500 grams, but it cannot be said that the device is heavy. In addition, the device is quite thin, which gives the gadget great ergonomics. The back panel is susceptible to fingerprints, and if it is not so noticeable in the white version, then the spots will stand out strongly against the dark blue background. All this suggests once again that it is better to use a case.
Display
Review Lenovo tablet Tab 2 A10 70L continue with a review of the display features. The screen of the device has a diagonal of 10.1 inches, and a resolution of 1920 × 1200 with an aspect ratio of 16:10. This resolution is enough to get a high-quality picture without obvious pixels. For such a price category, the resolution is very good, which, no doubt, pleases and raises the device one line higher than competitors in the same price category.
The tablet has an air gap, but this is not such a big minus. This is forgivable for a mid-budget device. The color rendition is natural, the screen is bright and juicy, but the realism of colors is observed. The manufacturer has calibrated this setting well. Viewing angles are top notch, which also means that the display is excellent.
The MiraVision setting is built into the tablet, which allows you to adjust many screen parameters. This refers to an atypical adjustment of brightness, but also sharpness, color balance, hue, as well as contrast and color saturation.
The display is bright enough for normal outdoor use, but in direct sunlight the quality may drop a bit. The minimum brightness setting is too high, which leads to the fact that in the dark when using the tablet, the eyes can get tired faster and there is a desire to lower the slider even lower, but this is not possible. You can fix this with third party apps.
The light sensor was not built in, so all brightness settings must be made in manual mode. However, most users already disable it, so it cannot be said that this is a big minus.
It is worth noting that it is still unknown what material is used to protect the display. There are opinions that this is a protective glass, but sometimes it seems that the front panel is high-quality plastic. It is worth considering that the protective surface resists scratches well, but does not have an oleophobic coating, so fingerprints remain easily. Here it is better to use a film.
As a result, we can say that the display turned out to be good and clearly worthy of its price.
Sound
The device received two speakers, which are located at the top of the rear panel and are distributed on the sides, which creates stereo sound or surround sound. Dolby ATMOS technology is built into the tablet, it is designed to significantly expand the sound stage. We can immediately say that Lenovo managed to achieve this. The sound is loud and clear, bass and low frequencies are felt.
Since the speakers are located at the back, it may be thought that this impairs the sound perception. However, they have enough headroom to compensate for the lack of location. While holding the tablet, do not close the sound holes with your hands.
In the mentioned Dolby ATMOS program, deep sound settings are given and there are several ready-made quality profiles.
Also a little about using the headset. If you turn on expensive headphones, then their potential will be revealed by 100%. As a result, we can say with confidence that with the sound of the tablet, everything is on high level.
cameras
In tablets, you should not expect anything from cameras. And in general, few people use them, except as a front camera for selfie photos or video calls. But in the reviewed tablet, everything is pretty good. So, the main camera received 8 megapixels and has autofocus. In good daylight, the pictures are of acceptable quality, the color reproduction of the environment is normal.
But focusing takes a long time, and when you zoom in, you can see that the detail of the photos is rather weak. If you take a photo in poor lighting, then the quality drops many times over, noise appears.
In the application "Camera" there are many useful settings, if you twist them, then the quality of the pictures may improve slightly. So, the most interesting setting is the HDR mode. It works quite well and is useful in many situations. However, during such photography, it is necessary that the camera is stationary. It is also worth noting that there is no flash, which reduces the quality of the photo in the dark. Videos are obtained, albeit in high resolution at 1920 × 1080, but still the quality is a little lame, and pixelation appears. Despite the shortcomings in the camera, there are also interesting features, for example, the anti-flicker mode allows you to shoot video from the monitor or TV screen without running lines.
The front camera is quite standard and will fit for taking pictures of yourself or using it for video calls, but the video quality will not be the highest.
Memory and memory card
The tablet is equipped with 16 GB of internal memory and 2 GB of RAM. If the RAM is enough for running applications and background processes, then the internal storage may not be enough. The fact is that it clogs very quickly, and in the version operating system installed on this tablet, not all applications are transferred to the memory card.
You can expand the storage with a flash drive up to 64 GB, which slightly improves the situation. In addition, there is a version with 32 GB of ROM.
Connection
Wireless modules are presented in the form of Wi-Fi, Bluetooth 4.0 and 3G/LTE. About Wi-Fi, we can say that it works well and fairly quickly, no problems were identified during testing - the connection is instantaneous, and the transfer speed is high. The Wi-Fi module supports all standards that currently exist.
Eat GPS systems, Glonass and Beidou. They all work well with maps.
When connecting an OTG adapter, you can not only connect a USB flash drive, but even network card USB-Ethernet for later use of wired internet. This possibility is not present everywhere.
Battery life and performance
The tablet uses a 7000 mAh battery. Despite the fact that the filling is quite economical, a long mode of operation will be provided. The autonomy was tested on PCMark, where the tablet lasted more than 9 hours with above-average brightness and Wi-Fi turned on. When the test was over, there was still 19% of the charge left, which is enough for at least an hour with the same high load.
In general, it will take at least 2 days to discharge the tablet with normal use. Charging takes about 4 hours from 0 to 100%. It is recommended to use the complete cable and power supply, which provide 2A current. Other power supplies may take longer to charge. During heavy games, the charging speed is significantly reduced, so in 30 minutes of playing the charge level rose by only 7%.
The "heart" of the tablet is a MediaTek MT8732 quad-core processor with a clock frequency of 1.7 GHz. This is a mid-range chipset that is quite power efficient. The Mali-T760 MP2 is used as a video system - a high-performance video accelerator, which, however, in this version has only 2 cores, but can support much more.
2 GB of RAM, only half of it is available to the user. In Antutu, Lenovo Tab 2 A10 70L shows more than 34 thousand points, which is an average result. However, in reality, the performance is higher than the tests show. The interface works smoothly and quickly, all applications open without the slightest delay.
Here in games the situation is average in every sense, so, in a fairly demanding game world Of Tank Blitz it is comfortable to play only at low and medium settings, however, in heavy scenes, there may be frame rate drops.
In well-optimized games like Asphalt 8 and Modern Combat 5, everything is quite good, it is comfortable to play at medium settings, there are no obvious performance losses and lags too.
In simple three-dimensional games, using various runners as an example, performance is at a high level, everything flies as it should. The situation is the same with 2D games, they don't have frame drops.
From all this we can conclude that the tablet, in principle, is suitable for games, but it will come out with problems in especially difficult options, you will need to lower the graphics settings.
Software
From the box, the tablet comes with Android 4.4 operating system, but immediately upon launch it can be upgraded to Android 5.0. To do this, you just need to connect to the Internet, after which the tablet itself will offer an update.
Lenovo's proprietary solution, Vibe UI, is used as the shell. At first glance, there are not many differences from standard version Android, these are slightly altered settings and overused shortcuts for standard applications.
There are no complaints about the operation of the system. Everything works quickly and smoothly. There are no slowdowns during transitions. Whole set android features works perfectly and flawlessly.
There are several pre-installed applications, among which there are a couple of special ones:
- SYNCitHD. This software allows you to back up your memory.
- WPS office. This office suite, it includes all desired applications for opening documents and editing them, creating presentations and a program for spreadsheets and calculations in them.
Outcome
Lenovo TAB 2 A10-70L is an interesting offer that fully justifies its price. Of the advantages, one can immediately note an excellent high-resolution screen, normal performance for many everyday tasks and support for 3G networks. The most tangible plus is an excellent sound system, which gives a truly quality sound, as well as high autonomy for a tablet with a 10-inch screen.
However, it was not without its downsides. This is insufficient performance for “heavy” games, frankly weak camera modules and the absence of an oleophobic screen coating.
But a tablet is not a smartphone. In general, the considered gadget is clearly worth the money.

- OTG support
- memory card support
- making calls (optional)
minuses
- weak cameras
- low screen resolution
Lenovo A7-30 is a rather interesting budget-level tablet that is suitable for surfing the Internet and watching video content. This device can not be called advanced and very powerful, but it copes well with the tasks assigned to it. Estimated price Lenovo Tab 2 A7-30 at the start of sales, depending on the modification, will be 170 - 200 US dollars.
Tablet computers, especially productive and inexpensive, are in ever-growing demand. One of the most affordable products are the products of Lenovo, which presented an updated line of tablets of the Tab 2 A series at CES and MWC 2015. Customers are offered tablets with a screen diagonal of 7, 8 and 10 inches: Lenovo Tab 2 A7-10, A7-30, A8 and A10. As you might guess, the numbers 7, 8 and 10 transparently hint at the screen diagonal size.
The main characteristics of the tablets of the series
Lenovo Tab 2 tablets have the following main specifications:
- A7-10 and A7-30 work on Android 4.4 with the company's proprietary interface, in the future it is planned to switch to Android 5.0, A8 and A10 - Android 5.0;
- built on the following hardware platform: A7-10 and A7-30 - quad-core MediaTek MT8382M, A8 - quad-core, 64-bit MediaTek MT8161 (MT8735 for LTE version), A10 - 64-bit MediaTek MT8165 (MT8732 for LTE version);
- screens with a diagonal of 7, 8, 10 inches and a resolution of 1024 by 600, 1280 by 720 and 1920 by 1080 pixels;
- A7 is available in “Wi-Fi only” (A7-10) or “Wi-Fi + 3G” (A7-30) modifications, A8 and A10 have a version equipped with a 4G LTE modem;
- Dolby certifications for audio paths.
Appearance, screens and design of tablets
Developing new series tablets, Lenovo engineers pursued the goal of creating an inexpensive, but solid device that would be convenient and pleasant to use. Therefore, the case of all models of the Tab 2 series are made of durable, non-slip and pleasant to the touch plastic. The assembly is thorough, nothing creaks anywhere.
The control buttons on the A7 and A8 models are on the right side, and the headphone and microSD jack are on top. The A10, whose main orientation is not portrait, but landscape, has all the control buttons and ports on the left side.
In terms of color diversity, Lenovo has come up with the following solutions. The cheapest model Tab 2 A7-10 is available only in black, A7-30 - in black, white, blue and pink, A8 - white, pink and blue, A10 - white and blue.
The screens of the devices of this line are seriously different. All of them are made using IPS technology, but matrices of different quality. In the most inexpensive device of the line, the A7 tablet, there is a matrix with a resolution of 1024 by 600 pixels. This is not very good, the pixel density is low and they are noticeable. The A8 has a better situation, its 8-screen has a resolution of 1280 by 720 pixels.
best device in this respect is the flagship of the Tab 2 A10 line. The screen with a diagonal of 10.1 inches has a resolution of 1920 by 1080 pixels. Of course, this is not Retina, but it looks good. All models are good when used at home. In sunlight, the brightness has to be turned up completely. A7 especially suffers from this, in which the screen fades strongly in the sun.
Hardware platforms and performance
All Lenovo Tab 2 tablets are built on the Mediatek hardware platform. Quad-core solutions used: MT8382M, MediaTek MT8161 (MT8735), MT8165 (MT873) for A7, A8 and A10 respectively. The graphics accelerator in all cases is Mali. Processors for 8- and 10-inch tablets support 64-bit instruction sets. Although the chips are budgetary, like all MediaTek products, they are quite productive. This manufacturer is gaining popularity and its solutions are found not only in the products of leading Chinese brands like Lenovo, but also in Sony and HTC, and these are the world's leading brands.
In A8 and A10, depending on the modification, different "systems on a chip" are installed to ensure the minimum cost. A model with LTE support is equipped with a chip that has a 4G modem, while tablets with Wi-Fi are equipped with chips without a modem. MT8161 and MT8165 differ from each other in performance: the first supports only HD screens, but the MT8165, which is in A10, is designed for Full HD. In general, Lenovo has carefully chosen processors that are fully consistent with other components. Exactly as much as you need - no more and no less.
RAM in the seven- and eight-inch models was supplied with 1 GB, in the top model of the line, A10 - 2 GB. In fact, for the first two models, they left a minimum that allows them to work normally on current versions of the Android OS. Everything is better in A10 with RAM, 2 GB look good today optimal solution. Moreover, 3 GB is really put only in the flagship models of tablets and smartphones.
LTE tablet models A8 and A10 are equipped with modems that support dual SIM-cards. Moreover, there are also 2 slots for SIM-cards in these tablets. There is also support for calls. If you wish, you can use these "pills" as very large phablets.
User memory in models A7 and A8 can be 8 or 16 GB, depending on the modification. The A10 has 16GB of storage. In any case, this is not enough for storing multimedia data. You need a microSD card. All Lenovo Tab 2 models support cards up to 32 GB.
It is impossible to ignore the pride of Lenovo engineers - the Dolby Atmos audio path, certified according to the norms of this strict standard. In A7, the work of this path is noticeable only in headphones. But in the A8 and A10, equipped with two speakers, careful work on the sound is already noticeable when using them. In headphones, everything sounds great. Of course, sound quality is a subjective opinion, but it should be noted that Lenovo approaches this issue even more carefully than Samsung.
Operating system and interface
The Lenovo Tab 2 A7 comes preloaded with Android 4.4 KitKat, the rest of the tablets come with Android 5.0. Either way, the operating system is safely hidden behind Lenovo's proprietary user interface. There is nothing special about it, it is easy to understand the principle of operation and control. The interface works smartly, lags and freezes are not observed.
Lenovo engineers and programmers took care of customers and pre-installed their suite of applications for data transfer, virus protection and Reserve copy. It is officially impossible to get rid of it, you can only remove applications by installing third party firmware. In principle, the proposed Lenovo is not so bad, but Google Play offers other solutions, among which you can find something more convenient.
Cameras
In the Lenovo Tab 2 A7, camera reviews are only present so that the manufacturer can report that they are. A7-10 equipped front camera 0.3 MP, sufficient only for video calls. A7-30 also received a camera on the back. But its resolution is only 2 megapixels and it is not possible to take normal photos.
In Lenovo Tab 2 A8 and A10, things are better with this moment. A8 is equipped with a main camera with autofocus and a 5 megapixel matrix. The front camera has a resolution of 2 megapixels. This is not bad, you can make good daytime photos. The A10 is even better: the front camera is equipped with a 5 megapixel matrix, the main one is 8 megapixels. This allows you to take pictures with quite acceptable quality, including selfies, if you have a desire to use the tablet for such shooting.
Batteries and battery life
Lenovo Tab 2 battery capacities are as follows: A7 - 3450 mAh, A8 - 4200 mAh, A10 - 7000 mAh. All devices are able to hold out with active use without a charge for about 8-10 hours, depending on the load level. It is clear that the fastest battery is discharged in 3D games. When surfing the net and reading time battery life, of course, there will be more.

The main peak of the popularity of tablets has already passed two years ago, despite the fact that the category of devices itself does not exist even ten. However, this does not mean that there are no suitable devices on the market for every taste and budget. It's just that only those manufacturers who are ready to experiment and work for a limited number of consumers remain. One of the largest is Lenovo. This company makes devices in all price categories - from ultra-budget to flagship, but at the same time sold at more reasonable prices.
A review of the Lenovo Tab 2 A10-70L 16GB (or 32gb) tablet will introduce us to a device that is already two years old in 2017, but, judging by the reviews, this does not lose its attractiveness, both in terms of its characteristics, so are the prices. The latter, by the way, was quite tempting at the start of sales, but now, on the wave of new devices in the manufacturer's lineup, it will please anyone.
Appearance and dimensions
The Lenovo 16gb device is available in two color options - white and dark blue. In the last frame around the screen black. The manufacturer has made several hints to consumers on how it is desirable to use this tablet. First of all, this is of course the aspect ratio of the screen. 16:10 in vertical orientation is convenient only for browsing the Internet. For all other use cases, a landscape layout is preferable. This is also indicated by the logo along with the front camera, located on the long side, as well as the headphone jack on the edge above them. Accordingly, already starting from this, the volume control and screen lock buttons with slots for SIM and microSD cards are now on the left short side. If, taking into account such an arrangement of control elements, to hold the tablet vertically, one might really think that a defect has been caught.
There is nothing outstanding in terms of Lenovo 16gb (and 32gb). About 250 mm long, 170 mm high and 9 mm thick. Once upon a time, this was the golden mean, but now, during minimization, the device can seem really large. Plus, it weighs a little more. half a kilogram, which, according to reviews, is not very convenient.
The frames, on the one hand, are too big, and, on the other hand, they are made deliberately for a comfortable game and a strong grip.
The assembly of the device cannot be called ideal . There are creaks back cover flexes, minimal twisting is felt. But it's all about the size. To force such big tablet to be monolithic, you need to make additional efforts, which are unlikely to be justified by the price. The overview only demonstrates the features of some characteristics, which additionally need to be evaluated in the context of personal use.
The display is the main advantage of the tablet
Obviously, the screen can be considered the main advantage of the Lenovo Tab 2 A10-70L. Manufacturers have long understood that this is what needs to be done. main focus. You can use a compromise camera and make the tablet a little larger, but if the picture is not pleasant enough, the consumer will not forgive. This device has a 10.1-inch IPS display. The resolution is even higher than Full HD - 1920x1200. But this is a feature of the aspect ratio. Plus, given the presence of only the software buttons of the operating system, these extra pixels are very appropriate.
The density is 224 ppi, which is very good for a 10-inch tablet, especially considering its price. However, the minus of Lenovo 16gb (32gb) can be considered an extra air layer between the protective glass and, directly, the display. It does not greatly affect viewing angles and other characteristics, but if it were removed, phenomenal results could be achieved.
For fastidious users MiraVision utility is provided which can be used to additional settings screen.
The next important point is brightness. The maximum value is enough for any conditions. This is not a record, but exactly what a tablet needs, which was originally conceived as home device. But at least it's a little annoying. It is unnecessarily high, and reading in the dark will be uncomfortable. no light sensor.
There is no exact data on what exactly protects this, such a successful display. Either good glass or very good plastic. In any case, the results of operation are positive, and this is exactly what we need. But unfortunately, no oleophobic coating- this means that sometimes you can experience inconvenience during interaction with touch panel. Yes, and fingerprints will remain larger than usual.
Performance and Memory
Many people leave the review of the hardware platform to the end, but this is not entirely true, because it depends on how all the delights of the screen can manifest themselves in high-quality video and demanding games. How many programs can be kept in memory, and how they will work, in general.
Chinese processor - MediaTek MT8732. Architecture 64-bit with 4 Cortex-A53 cores. The graphics chip is a more efficient Mali-T760 MP2, which, alas, does not work at full capacity with this CPU.
2 GB of RAM is a good indicator for its time, but now, given the fact that this is a 10-inch tablet, it can make it difficult. Probably, all modern applications will have enough volume, but when they are switched, each will be unloaded and launched from scratch. Another 1 GB would not be superfluous.
Benchmarks and practice show that in the process of working with the tablet interface and basic programs there are no problems, but when it comes to games - it's time for compromise.
The top Asphalt 8, World of Tanks Blitz, Modern Combat 5, Dead Trigger 2 will need to be tuned to get the desired number of frames per second. Or be content with the stuttering that comes with good graphics. And again, to understand the features of one review is not enough - you need to test it yourself.
There are modifications of the device with 16 and 32 GB internal memory. Considering that not the full volume is available to the user, the indicator is too small. Although expanding microSD cards. But android features 5.0 does not allow you to transfer applications to them completely. With an OS update, this shortcoming could be ignored.
Sound
Returning for a second to the design, it is worth saying that the only attractive design solution is the speaker grill, located on the rear panel on both sides of the camera. This is the usual perforation, which, as it were, crumbles around the edges. But, again, the fact that the speaker output occupies the entire width of the tablet is not an accident. In the Lenovo device there are several emitters at once, forming a kind of sound system. And in practice, it really shows itself well. The only negative is the sound direction from user. But, on the other hand, the device can be used as a replacement portable speaker middle price segment. Dolby ATMOS technology is responsible for the overall good quality sound, and in addition allows you to create separate profiles for movies, music, and so on. Of course, all these features apply to headphones.
cameras
Subjectively and according to user reviews, this is one of the most useless features in any tablet. Probably, many consumers would agree to completely abolish it, and for the same price to get extra memory or best display. But it can also be called a certain basic set, without which no manufacturer can do. This device has two cameras: the main one is 8 megapixels and the front one is 5 megapixels. Both are of average quality. And they are only suitable for situational shooting. Don't even expect any artistry. I am glad that there are settings in which, in good lighting, theoretically, you can get at least something.
operating system
Since, as already mentioned, the device is quite old, it runs on Android 4.4. But now, right out of the box, it can be upgraded to 5.0.1. It is hardly worth expecting further development. Of course, all this is complemented by the vision of the company's engineers, which is called Lenovo Vibe UI. Not everyone likes shells from Chinese manufacturers. Here it is smaller than it was before, but it still catches the eye.
Autonomy and interfaces
Battery - 7000 mAh. An excellent indicator that will give about 12 hours of work without recharging. Given this, even four hours to restore the charge to 100% may seem quite normal.
Of course, there are no problems with interfaces.
- dual-band Wi-Fi;
- bluetooth 4.0;
- LTE support;
- GPS, GLONASS;
- the ability to connect OTG via USB-connector.
Advantages and disadvantages
Pros:
- excellent screen;
- excellent autonomy;
- high-quality sound;
- 3G and LTE support.
Minuses:
- android 5.0;
- compromise CPU;
- no oleophobic screen coating.
- not enough internal memory.
conclusions
Lenovo Tab 2 A10-70L is a significantly outdated tablet that has a number of drawbacks related precisely to its age and features that were relevant at the time of release. If you close your eyes to them, you get a completely balanced device that will show itself perfectly in everyday use; will give a good picture and will work really long.
