Yeah this is one of the phone which I want in this budget a very nice mobile.
There are many countable feature added by xiaomi after the redmi note 3 .
Only thing which is disappointing from redmi note is downgrading of processor snapdragon which is negative thing for gaming purpose . 4 GB RAM which is very good experience .
Camera quality is very much improved in low light as compare to redmi note 3 but overall still now camera is not good at low light as per my opinion. This is bit problem in many devices of xiaomi although pictures are very much good in day light .
Video recording is very much good with features of slow motion and time lapse in which pictures are very much clear.
But most worst problem I faced in recording is with the voice high bass voice are recorded with very bad sound blurring of sound.
Touch is very smooth and faster in redmi note 4.
Battery backup is very nice a whole day with general usage 4000 mah but there is lat of time taking for full charging it requires more than 3 nd half hour which is problem.
I had been using this phone for about 1 years approx there no problem with battery no such big issues of hang in phones.
It has all its recent updates of miui interface which is very very much good as company has managed a very good usage interface without any extra memory usage and speed alteration thats pretty awesome by company.
N I m very much satisfied with this phone nd will suggest for this range to everyone.
