I understand you're having trouble with the fingerprint scanner on your Galaxy S25 Ultra when using a tempered glass screen protector. This is a fairly common issue with ultrasonic fingerprint scanners, which rely on sound waves to read your fingerprint.

To best understand the situation, could you provide a bit more detail?

What type of tempered glass are you using? (e.g., brand, thickness, "acoustic" or "ultrasonic" compatible)

Was the fingerprint scanner working before you installed the tempered glass?

Did you re-register your fingerprints after installing the tempered glass?

Here are some troubleshooting steps you can try:

Increase Touch Sensitivity: Go to Settings > Display and look for "Touch sensitivity." Enable this option. It increases the touch sensitivity of the screen, which can help the fingerprint scanner work better with a screen protector.

Re-register Your Fingerprints: This is often the most effective solution. Delete your existing fingerprints and re-register them after you've installed the tempered glass.

Press Firmly: When using the fingerprint scanner, make sure you're pressing firmly on the screen.

Clean the Screen: Ensure the screen is clean and free of any smudges or dirt.

Use a Compatible Tempered Glass:

Look for tempered glass specifically designed to be compatible with ultrasonic fingerprint scanners. These screen protectors typically have a cutout or a thinner area over the fingerprint sensor.

Some tempered glass manufacturers claim their products are "acoustic" or "ultrasonic" compatible. Read reviews carefully to see if other users have had success.

Consider a Different Type of Screen Protector: If you're having persistent issues with tempered glass, you might want to consider a thinner film screen protector instead. These typically don't interfere with the fingerprint scanner as much.

Check for Bubbles or Imperfections: Make sure there are no air bubbles or imperfections between the screen and the tempered glass, especially over the fingerprint sensor area.

Recalibrate the Fingerprint Sensor (if available): Some phones have a built-in option to recalibrate the fingerprint sensor. Check your phone's settings to see if this option is available.

Contact Samsung Support: If none of these steps work, there may be an issue with the fingerprint sensor itself. Contact Samsung Support for further assistance.

I also recommend checking online forums and communities for the S25 Ultra. Other users may have found specific tempered glass brands or models that work well with the fingerprint scanner.

Dear Samsung Member,

Greetings from Samsung Customer Support!

At Samsung, we always aim to provide impeccable services to our customers, and we highly regret that you feel this way.

Please follow these easy troubleshooting steps which may help in resolving this issue:

● Ensure that your fingers are clean and dry.
Note: If the skin on your fingertips is peeling or cracking, or your fingerprint is difficult to capture, the fingerprint ID on your phone may not work.

● If your fingerprints fail to unlock the phone while the phone is recharging, remove it from the charger and try again. If you are charging the phone with a charger and data cable from other brands when you use fingerprints to unlock the phone, they may interfere with the fingerprint sensor and cause the recognition to fail.

● Clean the fingerprint sensor with a soft cloth. Make sure the fingerprint sensor is dry and free from any debris that may cause the sensor to be unable to recognize the fingerprint.

● Remove the current fingerprint and set up the fingerprint again. When you touch the sensor to set up a fingerprint, make sure you set the entire fingerprint, including the outer area of your fingertip. Setting the entire fingerprint area enables successful fingerprint recognition with any grip.

● How to remove Fingerprint: Path: Settings> Biometrics and Security> Fingerprints> Fingerprint1> Remove> Remove again to confirm.

● How to Set up Fingerprint: Path: Settings>Biometrics and Security> Fingerprints> Fingerprint> Scan your fingerprint> Place your finger on the sensor, then lift it off when you feel a vibration> Continue> Reposition your finger each time to capture the edge of your fingerprint> Done> Fingerprint added successfully.

● Try Safe mode: https://www.samsung.com/in/support/mobile-devices/safe-mode-on-samsung-phones/

● Update the software if available: https://www.samsung.com/in/support/mobile-devices/samsung-galaxy-smartphone-how-to-update-software/

● You can reset your device by following the steps.
1. Kindly create a data backup of your device via the SMART switch mobile application or http://www.samsung.com/in/support/smartswitch pc suite.
2. Remember the Google password before resetting the device because it is required during initial setup.
3. If you do not remember the password then advise to reset (Forgot password) your Google account.

Path: Settings> General Management.>Reset>Temporary cloud backup or External storage backup>After backup tap on Factory data reset to reset your device to its factory default settings.
This will erase all data, including files and downloaded apps.
