I like the design of the phone as it got curved model from either side of phone and it is very much good for high quality games which can run smoothly without any stuck.i love all the features in phone like dual app, second space, etc.it almost looks like iphone with 5.5 inches screen.the sound system is very good I would like to rate 4.8/5.0 for sound.as much it is good it has some negative points too like the problem of earphone symbol which is very big problem in xaomi but keeping all that aside its very good phone under budget and runs very long.
