Video Introduction 539 views

Recently, Phone Repair Guru posted a video about iPhone 13 screen replacement. After replacement, “Important Display Message” pops up. What’s worse, Face ID is not available. Since the iPhone 13 screen includes no flood illuminator module and all the parts for the TrueDepth system are housed in the iPhone itself. REWA LAB speculates that the chip on the original screen has saved Face ID data. Transferring the chip to the new screen might solve the problem.
