Dear Samsung Member,

Greetings from Samsung Customer Support!

As per your concern, we would request you to kindly perform the following steps to resolve your issues.

Clear app cache through Device care:
Settings > Device care > Storage > CLEAN NOW.

Note: To delete files or uninstall apps that you do not use anymore, select a category under USER DATA. Then, tick items to select and tap DELETE or UNINSTALL.

Reset the device Settings: Settings > General Management > Reset settings>Reset all settings to their default.

For fingerprint issue: Have you checked your fingers?
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.

Please 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.

Please follow the below steps:
How to remove Fingerprint:
Tap on Settings >Biometrics and Security > Fingerprints> Fingerprint1> Remove> Tap on Remove again to confirm.

How to Set up Fingerprint:
Tap on Settings> Biometrics and Security>Fingerprints Tap on Add 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.
