Why is My Fingerprint Not Working on Android Devices?

Here are some common reasons why the fingerprint scanner may fail:

  1. Dirty or wet fingers: If your fingers are dirty, wet, or greasy, the scanner may not read your fingerprint correctly.
  2. Damaged fingerprint module: Dirt, oil, or even moisturizer residue can cover the fingerprint sensor and prevent it from working.
  3. Software glitches: A recent OS update or app conflict could cause the fingerprint sensor to malfunction.
  4. Hardware issues: In some cases, the fingerprint hardware may be damaged or unresponsive due to internal faults.

Fix: Android 15 Fingerprint Not Working Problem

Below are some effective solutions you can try to fix the fingerprint not working issue on your Android 15 device.

Fix 1: Recalibrate the Fingerprint Scanner

One of the first steps you can take is to recalibrate the fingerprint sensor using any official calibration tools provided by the manufacturer:

  1. Visit your device manufacturer’s support page (for Pixel users, you can visit pixelrepair.withgoogle.com).
  2. Download and install the fingerprint calibration software if available.
  3. Follow the instructions to recalibrate your device’s fingerprint sensor.

Note: In some cases, this calibration may only work temporarily and require recalibration after each reboot.

Fix 2: Re-add Your Fingerprints

Removing your old fingerprints and adding new ones can resolve recognition issues:

  1. Open Settings on your device.
  2. Tap Security & Biometrics > Fingerprints.
  3. Delete all saved fingerprints.
  4. Restart your device and re-add your fingerprints.

Fix 3: Check for Finger Dirt or Moisture

Ensure that your fingers are clean and dry before using the fingerprint sensor. Wet, oily, or dirty fingers can prevent the scanner from working.

  • Wash and dry your hands thoroughly.
  • Try unlocking your phone again with a clean finger.

Fix 4: Clean the Fingerprint Module

Fingerprint sensors often get covered in dirt or grease, especially after prolonged use:

  1. Use a soft, dry cloth to wipe the fingerprint sensor.
  2. If there is stubborn dirt, use a microfiber cloth with a small amount of alcohol-based cleaner to clean the module.
  3. Avoid using sharp or abrasive objects that may scratch or damage the sensor.

Fix 5: Restart Your Device

A simple restart can often resolve temporary software glitches:

  1. Press and hold the power button until the restart menu appears.
  2. Tap Restart or Reboot.
  3. Once the device restarts, try using the fingerprint sensor again.

Fix 6: Clear System Cache

Clearing the system cache can help remove temporary files that may be causing the issue:

  1. Turn off your device.
  2. Press and hold Volume Up + Power until the Recovery Mode screen appears.
  3. Use the volume buttons to navigate to Wipe Cache Partition and press the power button to select it.
  4. Once the process completes, select Reboot System Now.

Fix 7: Check for Software Updates

Fingerprint issues can also result from bugs in the operating system. Check for pending updates:

  1. Open Settings and go to System.
  2. Tap System Update.
  3. If an update is available, download and install it.
  4. Restart your device after updating.

Fix 8: Boot into Safe Mode

Sometimes, third-party apps can interfere with your phone’s fingerprint sensor:

  1. Press and hold the power button until the Power Menu appears.
  2. Long press Power Off until you see the Reboot to Safe Mode prompt.
  3. Tap OK to enter Safe Mode.

In Safe Mode, only system apps run. If your fingerprint sensor works in Safe Mode, a third-party app is causing the issue. Uninstall any recently installed apps that may be causing conflicts.

Fix 9: Reset Network and Security Settings

Resetting the network and security settings can often resolve biometric-related issues:

  1. Open Settings and go to System.
  2. Tap Reset Options.
  3. Select Reset Wi-Fi, Mobile & Bluetooth.
  4. Confirm the reset by entering your password or PIN.
  5. After the reset, re-add your fingerprint and check if it works.

Fix 10: Factory Reset Your Device

If none of the above solutions work, performing a factory reset may resolve deep software issues. Note: This will erase all data on your phone, so back up your files first:

  1. Open Settings and go to System.
  2. Tap Reset Options and select Erase All Data (Factory Reset).
  3. Confirm the reset by entering your password.
  4. Wait for the reset to complete, then set up your phone again and add your fingerprint.

Fix 11: Visit a Service Center

If the fingerprint sensor still doesn’t work after all these steps, there may be a hardware issue. Visit an authorized service center to have your phone inspected by a professional technician.

Conclusion

The Android 15 fingerprint not working issue can be caused by both software glitches and hardware faults. By following the solutions outlined in this guide, you should be able to resolve the problem in most cases. However, if the issue persists after trying all the fixes, visiting an authorized service center is the best option.
