Pros:
cellular call quality
5" 1080p screen
both rear and front facing cameras performs actually very well.
battery(3120mah)performs very good
dual sim device both sim slots supports 4G
gaming performance is very good
cons:
ringtone volumes feel a little lower in volume
gets warmed
1080p video recording not that great
biggest con is the storage area only about 16gigs
no expandable storage
this device is much superior than mi4 and also smartphones of this price range.so the value for money you get is very high.the quality of this device is very great than the rivals.i will give thumbs up for the screen quality and the camera performance.the camera quality is also great.but the video recording at 1080p from rear camera is not that great.
