Google Pixel 6 has a slow fingerprint reader — and this is the reason

Update: Google is reportedly now working on a fix for the Pixel 6 fingerprint problems.

You may have heard or noticed that the Google Pixel 6 has a rather slow fingerprint scanner. Google has seemingly heard these complaints, and it's now offered an explanation.

Replying to a user complaining about this sluggish scanning speed, the Made By Google Twitter account says the reason it takes longer than average is that the sensor "utilizes enhanced security algorithms."

This sounds like a fair exchange — speed for security — but Google doesn't actually detail in this tweet what exactly the sensor is doing above and beyond a typical under-display scanner. It doesn't specify anything beyond "Fingerprint Unlock with under-display fingerprint sensor" on the specs page on the Google Store either.

Optical under-display fingerprint scanners are a standard feature for Android flagship phones, excluding the Samsung's Samsung Galaxy S21 that uses an ultrasonic scanner. Having tested many such phones, we at Tom's Guide agree that the Pixel 6 is oddly slow compared to other optical under-display fingerprint scanners, such as those found on the OnePlus 9 Pro, or exterior-mounted scanners like on Google's very own Pixel 5a.

If you're struggling with your own Pixel 6's fingerprint scanner, there is one option that could help you. Enabling the "Increase touch sensitivity" setting has been reported to make the system faster to register your fingerprint, and therefore get you into the phone faster. However, after trying this ourselves we didn't really notice a difference.

Equally, the scanner may not be that secure after all. A Reddit user (via Android Police) has complained that his wife has been able to unlock his phone (registered to his thumbprint) using her index finger. He does mention that he's using a third-party screen protector, however. Perhaps this is an issue with how the phone interacts with an unknown extra layer between the sensor and your finger, rather than the phone having an issue itself.

Even with their finicky fingerprint scanners, the Pixel 6 and Pixel 6 Pro have still become two of the best Android phones we've tested this year. The Samsung Galaxy S22 will have some stiff competition when it arrives next year thanks to Google's blend of a cheap price, excellent photography and Tensor chipset-powered smarts.

    Actually, on the Pixel 6, the fingerprint scanner works fine, even with a glass screen protector.

    The secret is to first turn on enhanced fingerprint sensitivity and only afterwards train your fingerprints.

    As with all fingerprint sensors, it is critical to train using the ball of the finger, the base, the tip and both sides in different combinations and angles. You can get even better matching if you train the same finger twice, using two fingerprint slots.

    While not as fast as the capacitive sensors of the past, properly configured and trained, the Pixel 6 fingerprint sensor works reasonably fast and reliably.
