Redmi note 3.the big thing about this mobile is it’s battery backup.the past mobiles I have been using will not last long if I continously use net but this giant last more than a day even if my net goes on the full time.second is its processor.no hangs no lags.to say .maintain a free space of 1 gb to give some breathing time.a worthy kid to buy in its price segment.just luv it : )
