In redmi 3s prime the sound quality in good but not dolby. In this phone the setting have no many option and some setting options are minimaize so l face so many problems. It is look like a simple phone. Also desing is simple at the price of 8, 999/-. It have 3GB RAM and 32GB ROM but it not oparet like this. Some times it hang and swicth off automatically, how it possible in 3GB RAM. It is not good phone to use because it have over heating problem ( for many times) . Atlast my review is don’t buy this phone . In price 8, 999 many good phones avilable so go for different phone.
