Problem

An outdated operating system or firmware can lead to compatibility issues. This can lead to malfunctioning features like the Pixel 6A fingerprint sensor not working.

Solution: Check for Updates

The best way to resolve this issue is to update your Pixel device. Having an outdated version of Android OS can lead to an accumulation of bugs and glitches.
