Despite being a fan of this phone, I advise the Redmi Note 3. Smaller with same screen, bigger battery, better chipset. Make sure you go for the 32gb/3gb RAM version.owsm phn .yes when I put the device on manual brightness vr working smoothly.
I will try the same trick on the darker room with motion sensor games. thanx for ur hard work and pointing out the issue. really appreciate on your work. btw I think this issue is not with other devices such as redmi note 2, redmi2.
