I have been using this phone since 15 days .i must tell about the elegant design and the killer look .it has 64 gb and 4 gb ram which increase it performance and complete task in an instant second.
Pros
1) better camera
2) fast performance
3) good design
Cons
1) charger heating issue
Rather than that no complaint regarding the phone .the phone is so slippery
I recoomend to u buy MI A 1
