The mid-range Pixel 6a’s under-display fingerprint sensor has unsurprising issues
The new Google Pixel 6a
When the Pixel 6a was released last week, many noticed a slight improvement to the mid-range under-display fingerprint sensor over those found on the Pixel 6 and Pixel 6 Pro; the first word was that Google had used a new source for the Pixel 6a’s biometric reader. Even so, a major bug was discovered. The fingerprint sensor in multiple Pixel 6a units will allow anyone, and we mean anyone, to unlock the device.
Take the Google Pixel 6a
He went on to say, “The fingerprint sensor is inside the screen, just like on the regular Pixel 6. I scanned both thumbs so I could unlock my phone with either my right or left hand. However , my phone was flat on my desk and i decided to unlock it and i accidentally used my index finger and pressed it on the little fingerprint icon on the lock screen and it worked ????
If this happens on your Pixel 6a, try this workaround and let us know if it helps!
Another Redditor wrote that his wife was able to unlock his phone even though only his fingerprints were saved on the device. And even though he only registered his thumbs on the handset, the other fingers unlocked the device. He said: “Yeah, I asked my wife to try and she opened my phone in about three tries. Only my thumbs are saved and I have almost every other finger to work with, even with cleaning the phone between attempts. Before and after applying a screen protector.”
Even unregistered fingers on the Pixel 6a unlock the device on multiple units
And another post, this one written by “Remunos_Redbeard”, says, “Tons of people are reporting the issue, in tech posts and here on Reddit now that they’ve shipped. Widespread issue, unfortunately. I can unlock the 6a from my friend even though my fingerprint isn’t registered, and worried mine will do the same when it comes in. So for now at least, keep using a pin, password, or a pattern to unlock. And definitely don’t use fingerprint for banking or payment apps.”
