If your iPhone is covered by AppleCare+, you can use the AppleCare+ benefits to cover screen repair. If your iPhone is not covered by AppleCare+, you will pay out-of-pocket for the repair.
To claim your iPhone warranty, take the following steps:
1. Locate your proof of purchase. You will need this to verify your warranty coverage.
2. Contact Apple Support and explain the issue you are having with your iPhone.
3. Apple will troubleshoot the issue with you over the phone or online.
4. If they determine that your iPhone is covered by the warranty, they will send you instructions on how to proceed with the repair.
5. Follow the instructions and send your iPhone to the Apple Repair Center.
6. Once your iPhone is repaired, you will be able to use it as normal.
