I Love MI Note 4. I have gold color phone its look is very attractive. Though primary camera is 13 mp and secondary camera is only 5 mp, I think photo of secondary camera is better than primary. One of the best feature I noticed is that you can take selfie by touching finger sensor.
Phone is too alim and light weight, and due to 3 GB RAM it process very fast.
Its memory expendible feature is like mini computer 256 GB.
