I am a redmi note 4 user. I bought it last month.The phone is simply amazing. Bcoz of its 4 gb ram it never hangs. And the processor of the phone is really awesome bcoz it plays high end graphics game in a smooth play.The camera quality of rear camera is good.but front camera doesn’t performs well in recording videos.The best part of the phone is the IR BLASTER it is really helpful and fun for play.The negative part of the phone is the speakers I feel that Xiaomi should improve its speaker sound.Then the fingerprint sensor feature is awesome it unlocks the phone in 0.3 seconds.Therefore it is a best smartphone with the budget of 12000. I will rate it 4.5 out 5.i just like this product
