I bought this mobile on its official site. At first it working well also my 10-11 friends had also this mobile. After 3 days the homekey & recent key stop functioning. the options are selected automatically like opening google, opening the recent tabs, opening of one handed mode, opening of flash light etc. I also did factory reset but the same problem again arises & I did the reset with much difficulties like 20-25 attempts.
The specification shown for the mobiles are good but they should work properly otherwise waste of money.
