Freind I bought this smartphone in this diwali 2017 for 10500 rs . This smartphone comes with qualcomm snapdragon 820 fastest processor ever I use .
It has 4gb ram and 64gb of rom , it has not expandable storage that you could not expand the storage with micro sd card , it has only two nano sim slots . But you have 64 gb not neccesary to expand storage.
It has 8mp camera on front and 13mp camera on rear . Camera performance is decent not so good .
It has back miror finish looking awesome but fingerprint doing dirty back. If you drop this its back will broke . Lenovo know its problem and smartphone comes with sand finish back cover in box .
It has fingerprint sensor on front .the fp sensor is able to do seven types of tasks . Touch , long touch , press , double press , long press , right swipe and left swipe. You can adjust this in settings .its fingerprint sensor is also trackpad.
It comes with 5inch full hd ips display good video quality.
Sound quality is not loud but clear and satisfaying .
This is really best phone ever I used. No hanging , no lagging , no heating issues. This is awesome smartphone .
If you want to buy .
Go for it .
Its best phone.
