ios 15.2 wallet

Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).

You are correct. You cannot delete the Wallet App and it certainly will not fix any NFC related hardware issues. You have already tried to Force ReStart your iPhone as I had stated in my previous response and that did not work. I recommend that you have your iPhone examined at the Apple Store or at an Authorized Service Center for further diagnosis and a resolution.

You can delete it off your phone. You do have to re-download it from the cloud. However, I would recommend Metamask until they fix some of their issues as it stops working after a couple times. However, please back up your recovery seed.

Yes. You need to backup your recovery key, delete the wallet and re add it back. It broke both metamask and trust wallet for me.
