[Updated] Google Pixel 4a/5G & 5a 5G users report slow or delayed fingerprint unlock after March update (workaround inside)

New updates are being added at the bottom of this story…….

Original story (published on March 16, 2022) follows:

Developed by Google, the Pixel lineup was introduced back in 2016 as the successor to the Nexus series. Over the years, people have embraced Pixel devices because they offer raw power with stock Android experience.

Google recently made Android 12 available on older budget offerings such as the Pixel 4a, Pixel 4a 5G, and the Pixel 5a.


Having said that, Google Pixel 4a, Pixel 4a 5G, and Pixel 5a users are now complaining (1,2,3) about slow fingerprint unlock. Users say they are experiencing a few seconds delay when using the sensor on the lock screen.

The issue seems to have surfaced after the recent March update. Basic troubleshooting steps like restarting the phone, enrolling a new fingerprint, and fiddling with display timeout settings make no difference.

Here are some reports from Pixel 4, Pixel 4a 5G, and Pixel 5a users complaining about slow fingerprint unlock after the latest update.


After updating to march security patch my fingerprint unlock has an awful delay, wondering if anyone else have the same issue and if there us any known fix. Already tried removing and re registering the fingerprints,no luck.

Pixel 4a 5G – 2022 March update fingerprint speed I noticed that the fingerprint sensor speed changed in some cases. Screen off to unlocked takes way longer, roughly 2 seconds (it feels super slow). If i use the sensor to unlock from the the lockscreen its quicker than before. So pressing power button and then using the fingerprint is faster for me than just using the fingerprint. Anyone else noticed this?

Unfortunately, Google seems to be unaware of the fingerprint scanner issue and is yet to comment on the matter. However, we did come across a workaround that might help fix the problem.

Some say that after turning on the Always-on display, the fingerprint scanner went back to what it was prior to the update.

Same here on 4a. Workaround is to put AOD on.

For those looking to squeeze out some extra juice, this is impractical since they are now forced to choose between battery life and a slow fingerprint scanner. We hope Google fixes the problem in an upcoming update.

When they do, we will be updating this space with new information so make sure you stay tuned to PiunikaWeb. In the meantime, do let us know if the aforementioned workaround helped you in the comments below.
