Here’s what you can try — step by step:


---

🔧 Fix 1: Re-register fingerprints

1. Go to Settings → Security and privacy → Biometrics → Fingerprints.


2. Delete all existing fingerprints.


3. Restart your phone.


4. Go back and register your fingerprints again.

Make sure the screen is clean and dry.

Add two or three fingerprints of the same finger for better accuracy.

⚙️ Fix 2: Clear Fingerprint app data

Sometimes, the fingerprint service cache gets corrupted after an update.

1. Go to Settings → Apps → Show system apps (tap the 3 dots in the top-right).


2. Search for “Biometrics” or “Fingerprint”.


3. Tap Storage → Clear cache, then Clear data.


4. Restart the phone and re-register fingerprints.

🧼 Fix 3: Check screen protector

If you use a thick or non-official screen protector, try removing it temporarily.

Some protectors interfere with the ultrasonic sensor after firmware updates.



---

🔄 Fix 4: Wipe cache partition (no data loss)

1. Power off your phone.


2. Hold Volume Up + Power until the Samsung logo appears.


3. Use volume buttons to select “Wipe cache partition” → Power button to confirm.


4. Then select “Repair apps” (if available).


5. Restart normally.

🪄 Fix 5: Last resort

If none of the above helps:

Boot in Safe Mode to check if a third-party app causes the issue.
(Hold Power button → long-press “Power off” → choose Safe mode.)

If it still fails in Safe Mode, consider:

Backing up and doing a factory reset.

Or waiting for the next firmware patch, as Samsung usually fixes such bugs quickly.
