I am using this phone for 3 months now. I did not use kitkat and lollipop version of it because when I bought it, I directly update it to marshmallow. After using this phone for three months I would have to say that this phone is super smooth in use, no lag at all. Battery is ok but fast charging option makes it good. Overall I am impressed by its perfomance.
Awsome I love this phone.Great build quality feel nice in hand.
