I recntly purchased my redmi note 3 which is an amazing device with amazing full metal built quality.
have a very nice 16 m.p. camera and also comes with a finger print sensor with which we can also lock apps with the lastest update. The best thing which I liked about this phone is its battery life i.e. 4000 mAh. I m a gamer and I play high end graphic games whole day with full on use of whatsappa nf facebook n all. Still battery can survive one whole day with excessive use and use of speakers at full volume.
Mi is a good brand I like its quality. I also have purchased redmi 2 prime and mi4 before and I was very much satisfied before also but now this device i.e. redmi note 3 is amazing in this price over other brands at high prices and low specifications.
