If your iPhone’s Touch ID suddenly stopped working after installing iOS 13.1.1, you’re not alone. Several users have reported problems like failed fingerprint recognition, the inability to add new fingerprints, or the Touch ID toggle greyed out in settings.
The issue could be as simple as a dirty finger — or as complicated as a software bug. But in most cases, it can be fixed with a few quick steps. Here’s how to troubleshoot Touch ID issues on iPhones that support it, such as the iPhone 5s, 6, 6s, 7, 8, and their Plus models.
✅ 1. Clean and Dry Your Fingers
Touch ID won’t work if your finger is sweaty, wet, or dirty. Before trying anything else:
- Wash and dry your hands thoroughly.
- Avoid applying too much pressure when placing your finger.
- Make sure the Home button is clean and free of dust or smudges.
🔁 2. Force Restart Your iPhone
Restarting clears temporary system glitches that might interfere with Touch ID.
To force restart:
- Press and hold the Power (Side) button + Volume Down button simultaneously.
- Release both when you see the Apple logo.
After your phone restarts, try unlocking with Touch ID again.
🔄 3. Remove and Re-Add Your Fingerprints
If the existing fingerprint data got corrupted after the update, delete it and start fresh.
To remove old fingerprints:
- Go to Settings > Touch ID & Passcode
- Enter your passcode if prompted.
- Tap on each listed fingerprint and choose Delete Fingerprint
To add a new one:
- Tap Add a Fingerprint
- Follow the onscreen instructions — make sure to scan all sides and tips of your finger.
- Hold your iPhone as you normally would when unlocking.
🧩 4. Ensure Touch ID is Enabled
Sometimes the update disables your Touch ID settings. Double-check that it’s turned on.
To check:
- Go to Settings > Touch ID & Passcode
- Ensure the toggles for iPhone Unlock, iTunes & App Store, or Password AutoFill are switched ON.
🔁 5. Reset All Settings
If the issue is due to a conflicting system setting, a reset might help.
To reset all settings:
- Go to Settings > General > Reset
- Tap Reset All Settings
- Enter your passcode and confirm
⚠️ This won’t erase your data, but you’ll lose Wi-Fi passwords and other custom settings.
🛠️ Still Not Working?
If Touch ID is still not functioning after all the steps:
- The issue may be hardware-related — especially if the sensor is unresponsive or greyed out.
- Book an appointment with Apple Support or visit an Apple Store for diagnosis.
