I have had this tablet for 1 month now and I am pretty impressed by it.
It has a new mediatek chip which allows older parts, such as the GPU Mali 400 MP2 to work with android 6.0 hence why it is so cheap. This type of chip is most commonly found in recent low cost smart TV's.
720p HD is great. Tested this with a 4K video of youtube set to 720p.
Android 6.0 (Latest)
1GB of ram is acceptable, I have experienced no lagging.
Charges through Micro USB (There are many cheap tablet which don't)
Speaker is acceptable, loud on a flat surface.
Bluetooth 4.1 (Latest)
Up to 32GB Micro SD
The Alcatel apps are annoying but you can disable them. When I boot the tablet up it pops up saying my tablet is up to date. (Updated once already from 6.0 to 6.01)
Also the warranty app doesn't work but I think this is down to it not being officially out yet as it cannot find the server.
overall it does everything that £200 + tablet does for less than half the price.
GPU is a Mali400-MP2.
I have this tablet. Pretty good for the cheap tablet.
