Who has already purchased? Can I replace the battery with another? This is basically the only question on it.
Are there any exact dimensions of it?
In the Chinese gadget must be a spoon of tar, this time it is a battery.

[My nickname is]

In this Mali 450MP4 processor, which is very cool. Pro, even the smallest brakes in any games can be safely forgotten :)
I hope that there will be a version with 3G and a more capacious battery. Then get a great replacement for the best-selling U51GT-C4.
Although it is strange why in the antutu he is gaining the same amount as the above-voiced 51st model with the Mali 400MP2 video card.

And, most likely, in competition, he will not reach u51gt-c4.

[Forrrrest1]

My nickname is,
I think there will be neither 3G, nor more capacious Akum. If you can replace the battery, it would be nice if the topstarter would measure the battery with a caliper, then for this price, it's just a fairy tale. Here, by the way, only the front camera.
Well, 3g, you can buy a whistle if you really need it.

[Safty_max]

3G is not and will not be 100%.
Battery - well, as usual - weak.
I spread everything under it that I have, and this is:

The seller writes there is a GPS on it, how does it work? Only under the navigator I want to take it. In my opinion the best price for such a tablet with gps and with such performance.

what is the difference between c4 and c4w

[zss76]

Judging by the description onebayandaliexpressIn C4 there is less RAM - 512 MB instead of 1 GB, and there is also no GPS and no bluetooth (although it is written on ebay that there are 2.1).

I ordered just such a U25GTC4 (as written in the description of the Cortex-A9 and Quad Core RK3188 1.4GHz chip) 8GB. It does not have GPS either as well as bluetooth and RAM 512 Mb. And in general, a long-time weak device (I wanted to give my son and on it only simple games are going. And for some reason they charged me with charging via USB. I don’t know what to do with it now). Maybe a flashing will give something?

avlno weak device (I wanted to give my son and on it only unpretentious games go.

It can not be that weak, I have MOMO7 on the RK3066 (true with RAM 1GB) heavy 3d games normally pull, given that it is two-core, and here 4-core costs and the video card is also more powerful. You checked, maybe another percent was sent to you?

I think it's a matter of RAM. antutu showed that percent. only 2 cores written dream. And one more thing, today he was lying all day off and the battery was almost completely discharged, how can this be?

Check out his work as a GPS-navigator. Or advise other devices.

Something I can not understand how to install widgets. In the settings of the widgets did not find.

Understood - a long tap on the main screen. Ruth installed using Kingo Android ROOT.

[Knife12]

What are the dimensions of the battery (on the screen? 3.2? X65x100mm)? And is it possible to change to a larger battery? If so, what is the max size? Especially the max thickness of the battery is of interest.
Here is something suitable.
