The fingerprint scanner on the Galaxy S25 FE makes unlocking fast and secure. But sometimes it may stop recognizing your finger, making it frustrating to use. Luckily, there are a few practical fixes you can try to restore smooth performance.
Why Your Galaxy S25 FE Fingerprint Scanner May Not Work
- Dirty or smudged screen surface.
- Wet, oily, or dry fingers.
- Old or corrupted fingerprint data saved on the device.
- Software glitches or outdated firmware.
- Screen protector interfering with the sensor.
Clean the Screen and Your Fingers.
The fingerprint scanner relies on clear contact with your skin. Dirt, grease, or even small smudges can block proper recognition.
Wipe the screen gently with a clean microfiber cloth. Wash and dry your hands before trying again.
Re-register Your Fingerprints.
Sometimes the stored fingerprint data gets corrupted or doesn’t capture your finger properly. Removing old fingerprints and adding new ones ensures accurate scans.
- Open Settings, and then tap Biometrics and security.
- Tap Fingerprints, and then delete the existing entries.
- Tap Add fingerprint, and follow the prompts to scan your finger from different angles.
Check Screen Protector or Case.
Thick or poorly fitted protectors can cause the scanner to fail. Cases that push against the screen may also interfere.
If you recently added a screen protector, try removing it temporarily to test the scanner. Use only Samsung-approved protectors for better accuracy.
Update Software.
Outdated software can cause issues with the fingerprint sensor. Updating to the latest version often improves stability and fixes bugs.
- Open Settings, and then tap Software update.
- Tap Download and install, and follow the prompts if an update is available.
Reset Fingerprint Settings.
If the problem continues, resetting biometric preferences can help. This clears fingerprint-related settings without removing your personal files.
- Open Settings, and then tap General management.
- Tap Reset, and then tap Reset all settings. Confirm to complete.
If your Galaxy S25 FE fingerprint scanner is still not working after these fixes, you may be dealing with a hardware issue. In that case, visiting a Samsung service center is the best option.
