With Samsung S23, S23 Plus, and S23 Ultra, you have got a lot of options to secure and keep the device locked. Say it PIN, Password, Fingerprint, or Face Unlock; all of these have their own potential to secure the device; no one can beat the PIN and Password lock settings.

Fix Fingerprint Not Working with Screen Protector on Samsung S23 Ultra, S23, S23 Plus
Clean your Finger and Screen
Samsung S23, S23 Plus, and S23 Ultra all of these devices come with ultrasonic fingerprint sensor, which means the fingerprint sensor is integrated into the display itself. With this advanced technology, you still need to clean the fingerprint and display for smooth operations. Use any soft piece of cloth, a little wet, and rub it over the screen.
Press and hold the Volume Up button and Side button until the Samsung logo appears. Force rebooting is equivalent to removing the battery and placing it back; that’s what we used to do with earlier phones with removable batteries. But with the non-removable battery, there’s nothing you can do but force restart the system. This can pretty much resolve all the app and firmware crashing problems and fix minor glitches.
Check for Software Updates
In the Android market, Samsung is one of the biggest play to release software updates and security patches periodically. That’s why keeping the system up to date is advisable for the latest available One UI and Android OS. Apart from fixing software glitches, new updates bring new features.
- Go to the Settings app.
- Scroll down to Software Update.
- Select Check for updates.
- Select Download and install.
Delete and Register Fingerprint
Samsung fingerprint sensor has improved a lot that it was before. Over time, the biometric sensor is more secure. So the fingerprint that you have registered should match your fingerprint without any deviation. But it is impossible that your fingerprint will remain the same for a longer period, but you can add up to five fingerprints. Delete the existing fingerprint and register a new one.
- Go to the Settings app.
- Tap Biometrics and security.
- Select Fingerprints.
- Tap on Fingerprint and Remove it.
- Tap on Add fingerprint and register a new one.
Do Screen Test
We can also check for hardware faults in Samsung devices without requiring expert help. All the types of sensors, cameras, speakers, vibrate mode, etc. can be checked in just a few steps. Here’s how to check for fingerprint sensor damage,

Remove Screen Protector
Thicker the screen protector, the superior the protection. Well, that’s not the case. A thicker and incompatible display protector will make the screen and fingerprint unresponsive.
