I have use this smartphone around 4 months and I have never face any problem related to software or hardware. I have played some high graphics games like asphalt 8 , gangster vegas, etc. and I never face any lagging during these high graphics games in high visual quality. and other thing who impressed ne in this smartphone is fingerprint scanner which is very fast and responsible. its scan fingerprint on just type one time on scanner. and last one good thing his quality, its has metal body which gave premium look in just Rs 10k. Its good choice for those who have budget around Rs 10k
