Some possible fixes to the Pixel 7 and Pixel 7 Pro Fingerprint Not Working issue
Method 1: Increase the touch sensitivity
Method 2: Re-add your fingerprint
Method 3: Give the screen an extra second or two
Optical under-the-hood fingerprint sensors are slightly slower than ultrasonic scanners. You should bear this in mind and consider giving the device an additional second or two such that it is able to effectively scan your fingerprint.
Method 4: Install any pending updates
Method 5: Clean the screen
Not only your hands but your device’s screen should also be cleaned, especially the part where the fingerprint scanner is located. Even the slightest of dust particles might be enough for creating hurdles in successful scans. So you must clean the screen with a cloth or fabric before verifying if your device’s fingerprint sensor not working issue is resolved or not.
