I have the rear back taken off the phone and I want to reattach it. My pre-cut adhesive outlines the glass but not the metal camera bump. I ask because the transition from the glass back to the camera bump isn’t flush and the camera bump sits a bit higher (further from the phone’s frame) that the glass panel. Has anyone noticed this? Do you use two layers of adhesive between the camera bump and the frame? Do you use glue there? Thanks.
I think that the metal part of the camera bump should sit on top of the adhesive. Check out this video https://youtu.be/0kU3k18q0MA minute 9:04 might be helpful for your case
