I brought this phone flipkart on the flash sale. After 15 days of uses I share my experience.
Pros:-
1) Excellent Build Quality and Design 10/10
2) Crisp 1080p display
3) The Fingerprint Sensor and IR Blaster are very handy than expected.
4) The Battery Life is great.
5) The Snapdragon 650 is the best in the town you can get @ that price. No lags till this time, but you can see that these are initial impressions only.
6) The phone is really cool in nature. No heating issues reported.
Cons:-
1) They should have provided some protection of glass . But there are no issues reported about its quality.
2) The most discussed con of Redmi Note 3, its camera quality. Yes, as a Mi4i user, I can tell you that the camera quality lies in between Redmi 2 Prime and Mi4i. The details are enough for a normal user.
Overall phone is superb.
