Great guide! I recommend removing the Fingerprint Sensor as a whole. It will make it easier to remove the board, as the charging board has some adhesive, so you will need to pull a bit harder.
When screwing the sensor back, make sure to not tighten each screw all the way at first, but instead alternate between tightening one screw and the other. This will make sure that the sensor is properly aligned! This fixed the issue I was facing with reading some fingerprints after I had my screen replaced by a third party repair shop a couple of months ago. Two birds with one stone!
The guide was very excellent, however after putting the components all in place and booting back into the OS, the finger print reader refused to work anymore (both the original and a replacement one) and as far as i could tell there was no damage to where the reader connects. However, a more important issue is that with the replacement board my phone refused to recognize having the sim card inserted. If there is any software nonsense I have to go through it would be appreciated to have a pointer but at the end I had to fix the USB C port on the original board and reinstall it.
My sims no service after they made my old charger port. Is there any help please?
