My fingerprint ID stopped working. I tried to reset fingerprints but that didn’t help. Help!

Follow these steps. Try using Touch ID after each step:

1. Make sure that you have the latest version of iOS.
2. Make sure that your fingers and the Home button are clean and dry.* For the Home button, use a clean, lint-free cloth to wipe off any dirt or debris.
3. Go to Settings > Touch ID & Passcode and make sure that iPhone Unlock or iTunes & App Store is on, and that you've enrolled one or more fingerprints.
4. Try enrolling a different finger.

Hi,

Delete all the finger prints. Try a force restart of your phone by pressing home button together with sleep/wake button upto Iphone 6s or volume down button with sleep/wake button from iphone 7 and above until apple logo appears in the screen.

Then register your finger prints in touch id. Hope this may fix the issue. Cheers.
