After Google Pixel 6 users complained about the poor fingerprint recognizer performance of their mobile phones, recognition speed is slow, Google blamed the fingerprint sensor “with enhanced safety algorithm”, in order to add some additional protection, this is the reason for the delay identification is, or need more direct contact with the sensor.
But now Reddit has revealed that at least four of those Pixel 6 users have complained that strange fingerprints can also use the fingerprint sensor to unlock their Pixel 6 smartphones, making Gu’s earlier explanation that he used a more secure algorithm look awkward.
One Reddit user reported on the Google Pixel community that his Pixel 6 could be unlocked by his wife’s index finger, even though the only fingerprint registered on the phone was his own thumb. Most comments expressed shock or offered possible theories, suggesting that the problem might not be too widespread. Some users in the comments also reported the same problems on their own devices, varying in severity. The post also includes a video showing the problem.

The original poster used Omotion screen protector, which could affect the Pixel 6‘s fingerprint reliability. But one of the commenters mentioned that his phone doesn’t have a screen protector but still has the problem, and it seems that removing fingerprints from the phone and re-registering could solve the problem for some people.
