I don’t even remember whether the charger was there or not (like not), at home, and so these chargers do not get through.

Today I received a tablet. So far, so good. The screen is bright and juicy. The built-in memory fast response to installing updates and launching applications is very fast.
Everything turns off / on / reboots without any problems. Miracast in the settings did not touch, because I don't need it. Battery holds well. An antitu is 99600 points. Ruth received and did not try, because I don't need it now. I liked how it is assembled - it feels monolithic, nothing staggers / squeaks. There are no extraneous programs at all. here is a naked android version 8, which is a definite plus. Ordered in the official store on Ali -here.
Charging in the kit really is not, but because the whole mountain houses of these charges is a trifle. Included microUSB cable length is about 90 cm.
In our stores for this money (10,600 rubles) with this configuration of memory and a normal processor, there is nothing. There are only huavei and samsungi at a price 2-3 times higher.

160 USD is in Banggood, which is even cheaper, and yes, a normal device, especially pleased with the screen and battery.



Rep: (4)

many have such trouble. I updated the firmware, the problem did not arise anymore.

The display is recessed so that it looks as if you are looking into the well, so it is unlikely OGS.

Leave a small review. After a month of owning a tablet, I will say that I am not satisfied with the experience of using it.
Prior to that, he owned the Nexus 7 tablet (2013) for 5 years. Changed, as this dinosaur began to stutter when surfing in the browser.
Therefore, my opinion will be based on a comparison of teclast and nexus. Teclast - the screen is drowned when you drive your finger over the nexus. The touch is inadequate, I had to include a touch display in the developer’s menu, otherwise I have to poke into the playback scale for a long time trying to squander something. The color rendition is unnatural, and it did not work to bring it back to normal, I think that everything spoils mirakast. The rear camera does not focus. When launching the Yandex main page, the fonts in the news are washed, in other places I did not particularly notice.
Of the benefits - the overall performance is higher than that of the nexus, the sound is slightly louder.
Would I now take this tablet? No, I would not. But you will not know this until you buy it.

I wonder why you need my IMEI numbers?



Rep: (0)
* xxxxx0111,
and is IMED there? that's what interests me. Does CDMA support?



Rep: (1)
There is no MEID, only 2 IMEI. This means that CDMA is not supported.

That you again wanted strange from this tablet.
We compared the manufacturer of the first echelon and the second and third, and they are different in segments - the Nexus was not a budget tablet.
For me personally, the tablet is excellent, because I clearly understood that this is a state employee and what they saved on it.

I read a not very good review on bangood about poor WiFi reception. Is it so? In my village, there are about 20 meters to the router (a laptop and a smartphone are well received, 60-80%). Maybe the defective caught him?



Rep: (122)
* alex-chu,
Most likely defective, I have a router in line of sight, the 2.4G signal is slightly better than on the phone, 5G is slightly worse.

The fact that in Nexus'e at the time of release was pre-top iron, does not prevent him from being a budget tablet. In 2013, 200 USD is a budget device. All kinds of cubes that I bought in those days cost exactly that much or even more. For 300 USD I had a jiayu g4 phone, now comparable in hardware cost 60 USD.
Teclast is not the office that appeared the day before yesterday. The problem is that some first-tier companies can produce good low-end devices. And some second-tier offices do not learn anything and that 150 USD, that 1,500 USD does not affect the quality of the final product.
This is a lottery. I would buy, for example, Chuwi or Cube, it is quite possible that I would not have such problems that I encountered.

* junari,
The screen seems to be good. How do you feel about him? How much does the charge hold?

Rep: (122)
* alex-chu,
Slightly above wrote impressions. The feeling is twofold - it seems to be productive, but here there is a little backlash, the camera does not work there, the touches are incorrectly positioned here. You can use, with pleasure and comfort to use - is already more difficult. As for the charge, I will not say - it performs the role of a bedside tablet, but it feels like it will take 5 hours to feel.
