Google Pixel 6a is a smartphone whose great advantage is the use of a pure Android system without unnecessary producer overlays and quick updates that Google itself takes care of, which generally develops the entire Android system. Let's hope that an update on the operation of the fingerprint reader will appear soon, as a big problem has been detected in its operation.
There is information on the Internet that the Pixel 6a phone sometimes unlocks after using a fingerprint that has not been added to the smartphone as trusted. Problems with the operation of the fingerprint reader have also appeared in the past when it comes to the Pixel series. We are talking about Pixel 6 and Pixel 6 Pro phones. In the case of the Pixel 6a phone, we do not know the exact cause of the problem yet. It is possible that it is caused by manufacturing defects, but programming errors cannot be excluded. So far, Google has not officially addressed this matter.
