It is the latest smartphone of s-series. In Samsung, the fingerprint sensor has been changed to a new location which is better than s7 or s8. The battery backup has been increased and the infinity display of Samsung is too good. It feels very lightweight and compact. Although it has a 6inch screen it is very compatible to use. The camera is very good.retina scanner is very good face detection is not good much but better than previous. Storage is too good you can store so much in it. The design is very classy.I will recommend to use it. I will prefer it to all.
