Use fingerprint to sign in to apps
To use the fingerprint sensor with third-party apps:
• Be sure the app supports fingerprint recognition.
• Install the app and open its settings to adjust options, like enabling fingerprint unlock.
• Consult the app's help info for more instructions.
Why am I still asked for PIN/pattern?
For maximum security, you still need to enter your pattern, PIN, or password:
• Every time you power up your phone
• When more than 72 hours have passed since you last unlocked the phone
• When you go to Settings > Security & location > Fingerprint
• When the sensor can’t read the fingerprint
Fix a problem
Problem: Sometimes the sensor can’t read my fingerprints.
Each finger has a unique print. If you’ve added only one fingerprint, add more for other fingers
you want to use with the sensor.
The sensor may have trouble reading fingerprints if your finger is:
• Wet
• Oily
• Dirty
• Injured
If a registered fingerprint isn't working as expected, remove and re-add the fingerprint. If your
finger is injured, add fingerprints for your other fingers and use them until healed.
Problem: Fingerprint option disappeared from Security & location menu.
After each troubleshooting step, check to see if your issue is fixed.
1. Turn your phone off and then on again.
2. Check if a software update is available for your phone.
3. Check for app updates.
