- For this to break, it most likes must be a user damage issue.
- This is a flagship phone so it’s still under warranty since it just came out last year.
- It’s the newest phone so getting parts for self-repair will be tedious and sketchy
I recommend you *NOT* void your warranty and take it into an Apple store and pay the service fee to repair it there. It will still be under warranty and still have an IP68 protection due to the adhesives they use which will be reliable rather than you trying to repair this.
If you insist on repairing it yourself, iPhone 12 Pro Max Teardown will help you.
