Hello friends, I am sharing my experience with xiaomi redmi 4. I am sure that such type of phone can not existing in any other company in this budget. This is very good phone and has no lagging problem.both of camera quality is not good .i am using this phone for last 6 month guys. this phone has amazing superb metal body and very fast fingerprint scanner.Battery back up is good. But I have faced one problem is that this phone is very slippery back cover as many times it dropped from my hand.
