this repair is very common since the flex cable breaks just like shown in the video or if liquid travels to one of the sensors.
I've seen many cases where this cable develops an issue causing the device to bootloop, not charge correctly, no sound from the ear speaker, the proximity sensor doesn't work, face id becomes unavailable, front MIC doesn't work, and the ambient light sensor doesn't work.
the two sensors that I'm transferring are married to the logicboard and are needed for face id and true tone to work correctly
