We can tell from spy photos that the size of the display will not be below 5.5-inch, otherwise 2K resolution will not be reasonable. The lower jaw of the new phone’s front side is very narrow, so there may not be touch keys here and we expect to see virtual home, menu and back buttons on the display. The mid frame and back cover is joint with chamfer but no crevice, indicating a non-removable battery. On the rear side, we can see fingerprint scanner and double-temperature flash.
It seems Ulefone has not made decision over a few details, including the location for antenna openings, SIM slots, and USB port, given that the spy photos show 2 prototypes with some minor differences.
