- There were problems, but everything was resolved. I knew what I was taking, so complaints about a bad camera, pixels that are a little visible (170 PPI after all), etc. I do not have)
Operating experience - a week.
On the net of the problems that I encountered.
After the first launch, by going to Play Market I did not find many applications and games, and going through the direct link to the application / game, in the place where the "Install" button usually hangs, I saw the inscription "Not supported on your device." While I was looking for a solution to the problem in the internet, the Play Market was updated and the problem disappeared.
There was also a problem with watching videos in.mkv. The whole screen was in artifacts, the sound was terribly buggy and everything lagged. Solution: install MX Player and check the "HW + decoder" checkbox in its settings.
The next problem is the jumping audio volume in the video. During dialogues, the first 2-3 words sound quiet, the rest loudly, and so on with each phrase. The solution is to turn off Dolby Audio.
I hope this review will help those who are looking for a solution to the problems described above)

- An excellent tablet for not a lot of money. The battery holds up well if you follow the cycles. Nice, bright display IPS matrix that allows you to view from any angle. I took it especially for a child, if you watch cartoons for 5-7 hours, there is enough battery charge. The camera is honest 2MP. removes passably. The touchscreen is quite responsive and does not slow down like cheap China. GPS for a cold start finds satellites quickly, within 2-3 minutes. and does not plant the battery. kar samsungs. The sound is very loud and high quality, the speakers even after 3 months. do not wheeze.
- Things are good

- Good performance for its price, the interface does not lag, everything works quite smoothly. There is an android 5.0 though the update does not come over the air. Read on w3bsit3-dns.com or on the lenovo forums how to install. Not a bad screen, again for its price. Very compact, smaller in size than nexus 7 2013. Build quality, nothing creaks.
- Soiled body, especially the screen. There are minor bugs in the firmware, for example, on android 4.4, when charging, the screen is on all the time. There is no such thing at 5.0. Bad cameras, especially the frontal one, but I think it will do for Skype.
In general, a decent budget device. Perfect for kids and those who don't want to spend a lot of money on a tablet.
Getting to know the budget in every sense Lenovo Tab 2 a7-20f 8gb wi-fi blac k we unexpectedly realized that the tablet is actually quite good, moreover, it has more positive aspects than negative ones. Let's start as usual with the processor, which, although the most common MediaTekMT8127 is installed, has 4 cores, in total with 1 GB (not enough of course), allows the Android 5.0 operating system to work quite stably. A 7-inch screen with good color rendering, but a low resolution of 1024 * 600, of course this is not enough, but in general, for a price of $ 90 it is quite forgiven. The built-in battery does not have the largest amount of charge, but it is also enough for a full day. There is nothing to say about the cameras, since they are very weak and are clearly intended for some incomprehensible purpose, especially considering that now the 21st century is in the yard. Regarding the functions performed, the Lenovo Tab 2 a7-20f 8gb wi-fi black tablet fulfills 150 percent of its cost as it is quite convenient to read books, surf the Internet, and play weak games on it. In general, we recommend you for a full acquaintance. Oh yes, I would like to say about the build quality, which, in principle, is pretty good.

Everyone will agree that without gadgets in the modern world nowhere. But this also has a huge number of advantages... Today I will share my impressions of the tablet Lenovo TAB2 A7-20F.
If you are interested in the impressions of the tablet, the characteristics, you can skip a few paragraphs at once.
The old tablet, which was purchased for the family, fell into disrepair - it constantly hung up, scratches appeared and the speaker began to produce lower quality sound. We endured it for a while, but everything has an end. I, like many of Hayrek's children, always read reviews even before buying cosmetics, but this is not the cheapest technique!
____________________________________________________________________________________
Why did I stop at Lenovo? For the new year, we bought a new laptop from Lenovo, and I was very pleased with it! By the way, it is on it that I rivet this review.
At that time, I could not afford a tablet above 2500 hryvnia, and therefore my choice fell on budget gadgets. After rereading the specifications, I looked at the three Tab2 A7 tablets. In the first version (A7-10) there was no main camera, in the third (A7-30) there was support for a SIM card and 3G, but the price was higher than I expected. In the end, I chose the middle one, the hero of this review.

Specifications
The most "dry" I will hide in a quote, and comment on the rest.
Processor - MediaTek MT8127 1300 MHz.
The number of cores is 4.
RAM - 1GB.
Screen resolution -1024x600.
Screen type - TFT IPS, glossy.
The touch screen is capacitive, multitouch.
Weight - 269 g.
A 7 "screen is just fine for me, because 10" is too bulky for us. It is, rather, a "pocket" tablet, although I do not carry it in my pocket (there are thieves).
The operating system is Android 4.4KitKat and an upgrade to 5.0 is promised. I am very pleased with her.
As befits any even the most abnormal gadget, it has Wi-Fi and Bluetooth. The latter I do not use so often, but Wi-Fi perfectly catches in the whole apartment.
The built-in memory is only 8 GB, but it is possible to expand it up to 32 GB using SD cards. Not enough for me. but, since we do not need a large number of applications, while we save memory.
Now about the camera, here they disappointed me. Main -2MP, frontal 0.3. The latter is only suitable for Skype, and even then - in extreme cases.
Also, the tablet has a very good, in my opinion, Dolby Audio speaker.
Complete set: the tablet itself,
Charger,
Quick Start Guide.
By the way, I ordered it in the Rozetka online store for 2299 hryvnia.

Now comes the fun part! What is he like at work?
Quite fast, almost freezes (in Google Chrome, alas, this happens).
The maximum brightness is too high for me, especially after waking up and in the evening, I set it to 50-70%. Including to save power.
The picture is good, but don't expect any special miracles, after all, the screen resolution is the minimum standard for 7 inches. By the way, your fingerprints will remain on this gadget for sure. It freaks me out sometimes.
Now about the camera in more detail. Honestly, bad. You shouldn't even think about a photo for review or a selfie. There is no flash, which makes it difficult, and even completely cancels the evening or night shooting. This is a disadvantage.
But, in principle, for Skype (as I said above), and for sunny photos on the street - wherever it went.
I am attaching a photo to the main camera:
