Fingerprint sensor issue

[sehajxsaini]

In samsung s21 plus 5g  when we apply any tempered glass ,fingerprint sensor doesn't work even after increasing sensitivity for tempered glass

Try to remove previous fingerprints, add new fingerprints with the tempered glass applied, hope this will work 👍

Before applying tempered, remove old fingerprints then set them up again after applying tempered

It happens with tempered glasses. Like the above 2 comments suggest, please add new fingerprint with the tempered glass and try. It solves the problem.

Many recent S Series phone including S21+ has ultrasonic fingerprint sensor. Due to this your fingerprint won't work when you apply tempered glass due to its thickness.

You've to get a thin screen protector (like the one which came out of the box) for fingerprint to work properly. I've faced the same issue with my S21 & S10+

Dear Samsung Customer,

Greetings from Samsung Customer Support!

We acknowledge your query and apologize for the inconvenience caused to you and will surely assist you regarding the same and please follow the easy troubleshooting steps which might help to solve the issue.

When you scan your fingerprints on the device, be aware of the following conditions that may affect the feature’s performance:

• The fingerprint recognition sensor recognizes fingerprints. Ensure that the fingerprint recognition sensor is not scratched or damaged by metal objects, such as coins, keys, and necklaces.

• The screen protector supplied with the device may cause the fingerprint recognition sensor to malfunction. Remove the screen protector to improve fingerprint sensitivity.

• Ensure that the fingerprint recognition area and your fingers are clean and dry.

• The device may not recognize fingerprints that are affected by wrinkles or scars.

• The device may not recognize fingerprints from small or thin fingers.

• If you bend your finger or use a fingertip, the device may not recognize your fingerprints. Make sure to cover the entire fingerprint recognition sensor with your finger.

• To improve recognition performance, register fingerprints of the hand used most often to perform tasks on the device.

• In dry environments, static electricity can build up in the device. Avoid using this feature in dry environments or before using the feature, discharge static electricity by touching a metal object.
Note: You should make sure to use the highest central parts of fingerprint or the most curved part of fingerprint when you register or scan fingerprint
