I was a user of xiami redmi 4 .i bought it from flipkart .first of all about the sound receptors, the quality of the sound is very sound.it is not audible at all.now about the user friendly, it is a user friendly phone but not in all sense.it is not userfriendly in exeptional cases. Now about the style and design of the phone, it has a very bad style and it is not smooth but a kind of rough surface.now about the other features of the phone, it has MI remote which can be connected to any devices like tv, Ac.etc.its actually a cool feature.now about the look and feel of the phone, it has a good look but lack many other feels, it is very big in size as its so hard to handle.now about the value for money, actually it is very cheap so that it can be occupied by the poors.
