This display is an absolute scrap! It has no function. Have already changed frequently a display from 4 and 4S and he received so far always delivered functional displays. Up to this time. The whole cell phone disassemble, install screen and reassemble and then realize "display does not go" Then reinstall old display to send back the defective, so that it can be checked. Whoever wants to dismantle Iphone 3 x completely, should be here buy display
