Face ID not working
So just bought my brothers iPhone 13 - worked for him perfectly and for me aswell, except I started to get problems with Face ID. When I first set up the phone Face ID worked, but it at one point didn’t work so I was triggered and deleted that Face ID and tried to set up a new one, but now it shows all the time either : Move iPhone a little lower or higher.
Problems started when I downloaded the IOs 16, but now it has a new update and I updated it and the issue remains.
Any ideas?
iPhone 13 Pro, iOS 16
