How to fix iPhone 12 Pro rear camera lens sheet？
I searched the entire webpage, only to find some ways to open the back cover, maybe my search method is wrong.
You’ll need to open the device to remove the camera as when you remove the glass it may damage the lens itself and it will cost you a bomb. So its better to open the phone entirely and change the lens. Hope that helps :)
This is just a lens cover. You can get a replacement set here for 9.99
They attach to the lens bezel with an adhesive. There’s a youtube video on how to replace them.
With the replacement lens covers here, the adhesive was pre-attached. You peel off the brown paper ring and just stick it on. Just be gentle and keep everything clean and dust-free. Dig too hard and you could damage the actual lens.
