We recently replaced the oled on an iPhone X for a customer and discovered they had a cracked projector sensor. This caused their Face ID and cameras to stop working. We’re sure you’d like to know if that can be fixed, well yes it can. We at CellDr can replace this sensor l, the downside is Face ID will still not function. The only fix for this is to get it replaced by Apple so it can be paired to the phone to get Face ID functionality restored.
