Step #8. Head over to Sensors → Fingerprint and then tap on Normal.
Step #9. Reboot your device once you see the Pass message show up
This solution almost fixes the Galaxy S9+ fingerprint sensor issue, however, if it persists, head on to the next solution.
Solution #2: Disable Fingerprint Gestures
To ease the use of phone and inspired by Google and other Android OEMs, Samsung introduced gestures for the fingerprint sensor on the Galaxy S9. To find out whether this feature is the culprit;
Step #1. Go to the Settings app → Select the ‘Advanced features’ in the settings menu.
Step #2. Scroll and find ‘Finger sensor gestures’ to disable it.
Step #3. Reboot your phone by pressing down and holding the Power button and check to see if the issue has been resolved.
If this solution fails to solve the issue again, head back to the same menu and enable the gesture again and try the final fix mentioned below.
Solution #3: Traditional Fingerprint Setup
This solution may appear like a piece of cake, but may even work for some. During the fingerprint setup, Samsung asks you to swipe your finger rather than its earlier method of tapping it on the sensor a number of times, to make the process of fingerprint recognition faster. Maybe this is causing an issue and hence try resetting it again by the following method:
Step #1. Follow the steps from 1 to 2 as mentioned in our Solution #1.
Step #2. Reset your fingerprints without using the swiping motion, which you can set up by following the steps mentioned in ‘How to Set Up the Fingerprint Sensor on Galaxy S8 and S8 Plus.’
Note: Make sure to curve your finger over the sensor multiple times so that it is registered from all angles.
In none of the above fixes help, wait for Samsung to update its software to get rid of this bug forever.
