The XZ2 comes in a glossy finish, while the XZ2 compact sports a a non-scratch polycarbonate finish. Both phones have Gorilla Glass 5 protecting their full-HD LCDs.

According to Venture Beat, the 19-megapixel camera on the back is the same as is found on the XZ Premium and the back of the phone also boasts a fingerprint scanner.
