The built quality is nice, look like premium mobile.
Few aspects are: -
1) The screen clarity is very nice, Still it is hd but screen clarity is look premium.
2) the camera clarity is awesome in daylight but it is suffers from noise in night, but it is manageable because you cant get 13 mp at RS 9999, anyone also telling the picture resolution 4096* 2304 from camera is 10 mp, disable the full screen mode in camera setting, you got 13 mp resolution pic.
3) Performance is Nice, heavy games like mc4, nfs MW, subway surfer run smoothly, temple run 2 is playable at high graphic setting without lag, but six guns suffer from minor( sometimes) lagging.If you want more performance then in battery setting disable the CPU power saving mode( consume more battery) .
4) App is movable to external SD.No problem of available memory.
5) Ram is available than 400 MB ram by running all preinstalled apps.More than sufficient ram is available .
6) Sim works on 3g.
7) And last Battery backup is mind blowing.IF you are moderate user of mobile then you get a backup of 2 days.
8) Touch is fine, If you use mobile 2-3 days the you does not feel that touch is not smooth.Touch is At the price of rs 9999 is reasonable.
Overall nice buy because you cant get killer specs at the price of rs 9999.If any is planning to buying this product can buy but see the service centers first .
