Other than checking the debug info and then searching the internet for similar issues and fixes, I'm not sure where to go from here. Sounds like it might be critical.
I have 4 smashed S9s here, so I'd like to swap the camera out. I just can't access the back of the phone. The glue that holds the glass is solid. 3 minutes under the grill and I still can't get it to lift. PITA
I've tried this and the 3rd party app has the same issue.
