Fixing iPhone 15/15 Pro Fingerprint Scanner Issue

Is your iPhone 15 or iPhone 15 Pro’s fingerprint scanner not working as expected? The fingerprint scanner, also known as Touch ID, is a convenient and secure way to unlock your device and authorize transactions. When it malfunctions, it can be a frustrating experience. In this guide, we’ll explore practical solutions to help you resolve fingerprint scanner issues and ensure that Touch ID works reliably on your iPhone 15 or iPhone 15 Pro series.

Tips to Fix Fingerprint Scanner Issues on iPhone 15/15 Pro Series

1. Clean Your Fingerprint Scanner

Over time, fingerprint scanners can accumulate dirt, oils, or residue, affecting their accuracy. Gently clean the scanner with a microfiber cloth or a screen cleaning solution. Ensure your fingers are clean and dry when using Touch ID.

2. Remove Screen Protectors or Covers

Some screen protectors or cases can interfere with the fingerprint scanner’s functionality. Remove any screen protectors or cases that might be blocking the scanner and test Touch ID without them.

3. Reconfigure Your Fingerprints

If your existing fingerprint data is corrupted or outdated, reconfigure your fingerprints. Go to Settings > Touch ID & Passcode, enter your passcode, and delete your existing fingerprints. Then, re-add your fingerprints, following the on-screen instructions carefully.

4. Update iOS

Ensure your iPhone is running the latest iOS version. Apple frequently releases updates that include bug fixes and improvements, which can address Touch ID issues. Go to Settings > General > Software Update to check for updates.

5. Check for Hardware Damage

Examine your iPhone’s home button and the surrounding area for any physical damage or debris that might be affecting Touch ID. If you detect any issues, contact Apple Support or visit an Apple Store for assistance.

6. Enable Rest Finger to Open

In your iPhone’s settings, go to Accessibility > Touch > Rest Finger to Open. This feature allows you to unlock your device by resting your finger on the home button without pressing it. Enable it if it’s turned off.

7. Reset All Settings

If Touch ID issues persist, consider resetting all settings to their defaults. Find this option in Settings > General > Transfer or Reset iPhone > Reset. Note that this won’t erase your data but will reset system settings, potentially resolving software-related problems.

8. Contact Apple Support

If none of the above steps resolve the issue, contact Apple Support for assistance. There may be an underlying hardware or software problem that requires professional evaluation and repair.

9. Use an Alternate Fingerprint

If you’ve registered multiple fingerprints, try using a different one to see if it works. This can help determine if the problem is specific to one fingerprint or a broader issue with Touch ID.

Consider Face ID

If Touch ID continues to be problematic, you can use Face ID as an alternative biometric authentication method if your iPhone supports it. Set up Face ID in Settings > Face ID & Passcode for a seamless unlocking experience.


By following these tips, you can troubleshoot and potentially resolve fingerprint scanner issues on your iPhone 15 or iPhone 15 Pro series.
