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!

This guide will help you to replace the charging board - definitely not too difficult. I replaced my board after my A71 stopped charging when I inserted the USB C cable. First it wouldn’t fast charge and then wouldn’t charge at all.
