I have used this mobile for about 1 month now and feel this device has great performance even after installing many apps.The camera picture quality, battery backup and the display resolution with its light weight body all together add up the advantages of this phone.
The tough glass and the rear antigrease coating which resists scratches and stains on it is really awesome for a non removable panel but still it is not enough as I have got some minute scratches which does not bother the look or it does not disturb much.
