The worst mistake of my life was to buy this foolish device. It was good when new, though not as expected before buying this mobile. Because the camera quality, operating system, less ram and hence worst multitasking, rom too was just 6gb. After few days of buying it got junked completely because it was automatically rebooting, hanging and buffering the much. Also the CPU was getting heated up too much.
And the worst was the battery backup problem. It got so rottened that after being fully charged it was not even working for 4 hours while using mobile data.
My friend suggested me to format the device, so I did the same, but still it had some irrevocable problems that can't be solved.
And At last I had to change my phone.
It was really a very bad experience.
Whenever u buy a smart phone do check -
1) Whether operating system is latest or not, if not avoid that one if you can.
2) Check processor.
3) Camera quality.
4) Battety backup.It should be of at least 2500-3000 mah power.
