An as-of-yet unknown Nubia device has popped up on GeekBench with the model number NX591J, sporting Android 7.1.1 Nougat, 6GB of RAM and a Snapdragon 617 chipset. This could be a cheaper Nubia Z17, whether lite or mini s. Outside of the single-core score of 1080 and multi-core score of 2921 there's nothing in the GeekBench listing to indicate which Nubia device this is. We expect to find out more as more leaks or hopefully an official announcement come. Thanks, Sukhdev for the tip! Source | Via
