Pixel 6a. Just upgraded from Android 12 where the fingerprint reader worked decently. Now on A13 and although previously registered (on A12) fingerprints work, I cannot register any new fingerprints. Repeatedly get the "Couldn't process fingerprint. Please try again" error. This previously occurred on the most recent beta of A13 but once I rolled back to A12 fingerprints could be read.

On the beta I did a factory reset and it didn't fix it. I then couldn't even register a single fingerprint so extremely reluctant to do another factory reset. At least right now I have one registered fingerprint that works.

Thats a shame. Im not even going to mess with updating to A13 for a few days at least....maybe not till next week.

Mine working okay. Doesn't seem any different 12 vs 13B vs 13S. Do you have the warranty? This could be an issue with the sensor itself.

Another user reporting FP issue after the upgrade. 12 was okay but 13 doesn't work with registered FPs nor letting me add new ones. Sigh.

I never had issues with 12 and don't have issues with 13. I do not use any screen protectors at this point but I have one coming.

You guys need to redo your fingers twice and increase sensitivity in settings.

So it turns out that FP reader with A13 does work well with dry skin now. I just washed my hand with water and it let me register. My hands are usually very dry so this is going to be a problem..

Edit: moisture doesn't help with recognizing fingerprint when I tried to use it. Instead, I found the spot on the sensor it works better (slight upper left part) . This is absurd but at least I figured out the way to use it.

Me too. Had a shower and it worked fine until my hands have now fully dried out and yes I have dry skin naturally.

This FP is just making me go crazy, almost slowly worked in 12, since 13, it's just not working at all, I succeed register 4 fingerprints (with only 2 thumbs...), it took me about 20 minutes... but after, it never recognizes me... The only change is that, since 13, this phone ask my password faster than 12. In fact, after 2 tries. Wow, really impressed by the Google hard work on Android 13. I'm starting to think to ask a refund, I'm starting to regret my good old xiaomi mi mix 2s with his back FP, fast and reliable.....

I had some user errors lol on the FP origninally but it was only in the way I was placing my finger on the sensor. It's a bit different with the screen having a "spot" to place your finger on, rather than a seperate part of the display like hte 3a. You kind of have to "push" into the screen for a split second to take. Once I figured that out I was able to use FP no problem.

I had the same issue as you on a13 (beta and stable) after about 1-2 days clean install but didn't seem to have any issues on a12. I was almost ready to downgrade back to a12. However, i later learned that it was due to my dry fingers.

Note: On a13, i do have issues with fingerprint sensor in bright sunlight. It won't recognize my fingerprint at all

Like earlier stated, a "firm" initial press seems to make it work most times, but they definitely need to keep working on this.

    I wish they would leave it on the back or put it on the power button. Never had a problem with those

    Well, I have complete different experience.

    I was on A13 Beta where FP was most inconsistent..

    After installing A13 Stable, it's better than A12..

    No factory Reset, Nothing

    Same issue, I re-scanned my fingers, but it didn't help much and even the scanning seems to be struggling.
    I have figured it out that you have to press the finger REALLY hard in order to work properly. This wasn't the case with Android 12 and I hope they fix it.

    You may have to factory reset unfortunately. That "fixed" it mostly on the beta.
