GOOD THINGS:-
If I talk about its good things then the first thing that comes in mind is its battery, Battery was awesome. It long last about 12 to 13 hour, if you watching 3 movies continuous or if you surfing internet or youtube continuously. and now move on next, the second good thing is that it has dual sim support with 4G so, you can use this tablet as mobile. it comes with android lollipop 5.1 . now speaking about its camera, font camera is 2 MP as I said earlier. camera quality is average. back camera is 8 MP as I said earlier, back camera was good. it has auto focus. Now speaking about display, display brightness was awesome and it has also reading mode that you use while reading.
BAD THIINGS:-
If I talk about its bad things then the first thing that comes in my mind is its Rom, it has only 8 GB which is not sufficient for any android user. about 5.5 Gb space has already used by system memory then you have left very less memory for external apps. whatsapp, facebook, messenger and instagram. this is important app for any user but you install these four app then you would have no space left for further any new app. second bad thing is its charging speed, it took 4 to 5 hour to fully charge.
