The render, coming from an unknown source, is in no way official, so take it with a grain of salt. It depicts the front side of U12 with very thin bezels. Since there is no room for fingerprint scanner on the front, it can be assumed it will be placed on the rear of the device. That is all. Other rumours, unrelated to this render, promise that U12 will come packing a 4K display and dual camera setup; some even say that there will be no fingerprint scanner at all.
