Test the sensor
Your Samsung Galaxy S22 is well equipped to diagnose any faults in its hardware. This includes the fingerprint sensor as well. To run a check on the under-display fingerprint sensor, simply go to the dialer app and type *#0*#. Tap on ‘Sensor’ and select ‘Normal Scan’ under Fingerprint Test. Additionally, check the display for any hardware issues as well. If the tests do not return any hardware faults, proceed to the other fixes in this list. If there is an issue with the hardware, you will need to take your phone to a professional repair centre.
Restart your smartphone
Restarting your smartphone is the first thing you can do in order to fix any software-related issues. A quick restart resolves any background glitches and resumes normal functioning. To restart your Samsung Galaxy S22 series smartphone, simply long press the power button on the side and select ‘Restart’. If the touchscreen is totally dysfunctional, press the Volume Down key and Power key together until your phone shuts down. Restart your phone by long pressing the power key again.
Clean your finger and the phone display
The most likely reason behind the fingerprint sensor not working on your smartphone is a dirty display. While using your phone under humid conditions, it is quite common for sweat to stick to the phone’s screen and create some trouble. Simply wipe your phone down with a microfibre cloth and try again. If your S22’s display is fine, it may not be registering your fingerprint because your finger is too dry or chapped. Try using the fingerprint scanner with moisturized hands and see if it works.
Increase touchscreen sensitivity
If you recently installed a screen protector over your phone’s display, you need to increase the touchscreen sensitivity along with it to make sure everything works as intended. Since there is an additional layer between your fingers and the touch display, increased touch sensitivity is essential to ensure a lag-free experience. Go to Settings>Display and tap the toggle bar next to touch sensitivity to turn it on.
Remove the screen protector
If the under-display fingerprint sensor doesn’t work even after increasing the touchscreen sensitivity, take off the screen protector and try again. Sometimes, air bubbles get between the screen protector and the phone’s display and prevent an ideal connection between the two. To minimise any issues with the screen protector always look up whether it is compatible with your phone’s manufacturer before buying it.
Register two fingerprints for the same finger
While Samsung Galaxy S22’s fingerprint scanner thoroughly maps out your fingerprint in different positions, there may still be certain positions where it takes time to register the print or doesn’t register it all. To get rid of this issue, register the same fingerprint twice and make sure you cover every possible position while scanning it. Your Samsung Galaxy S22 allows you to register prints for multiple fingers, making it easy to unlock your device using either hand. If all fingerprint profiles are occupied, delete one and register an extra set of prints for the finger your use the most to unlock your smartphone.
Update System Software
If you’re using an old version of the system software, chances are that developers fixed the fingerprint scanner bug in a later update. Here’s how you can update the software version of your Samsung Galaxy S22.
Step 1: Go to Settings.
Step 2: Scroll down and select ‘Software Update’.
Step 3: Click on ‘Download and update’ to install the latest OS version on your smartphone.
