it says "Touch ID, Unable to activate Touch ID on this phone". When I go to settings and put in the passcode, all the settings are disabled and the added fingerprint is greyed out. If I try to enable any of the settings I get "Failed, Unable to complete Touch ID setup. Please go back and try again".
iPhone 6s Plus
Follow these steps. Try using Touch ID after each step:
- Make sure that you have the latest version of iOS.
- 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.
- Your finger should cover the Home button completely, touching the surrounding metal ring. While Touch ID is scanning, you shouldn't tap too quickly or move your finger around.
- If you're using a case or screen protector, make sure it doesn't cover the Home button or the surrounding ring.
- 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.
- Try enrolling a different finger.
Still not working?
If the previous steps didn't help, you see "Failed—unable to complete Touch ID setup", or either of the following happen when you go to Settings > Touch ID & Passcode, take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support:
"Touch ID, Unable to activate Touch ID on this phone".
