I brought this phone yesterday and I have been use it from 3days but I did not see any lag on this phone. The look of the phone is damm good camera quality is very good with in this price statement. On 16GB rom I have 10.43 GB useable storage. Battery bakup is quite good. But I have faced heating issue when I play d-day, Asphalt 8 like high-end games.The display quality of the phone is just like super amoled.
