GrapheneOS Pixel 7: no issue with fingerprint 👍
Workaround for Android 15 QPR2 fingerprint firmware glitch on Pixel 9 (non-Pro)
Pixel 9 here. No fingerprint functionality after a full shut down and a restart. Will try more restarts and report back.
6a no issue with fingerprint unlock
Pixel 9 as well, fingerprint option disappeared after a system update, persisted through the first shutdown cycle, then came back after a second.
No issue on 6th,7th and 8th gen pixels.
Test models :
- 6a, 6, 6 pro
- 7, 7a
- 8,8 pro
Unfortunately no pixels 9th in my collection to check.
GrapheneOS changed the title to Workaround for rare Pixel 9 fingerprint firmware glitch with Android 15 QPR2 .
Second Pixel 9 with GrapheneOS at home, same issue happened, resolved after 3rd shutdown cycle.

I have the same issue on my Pixel 8 (Stock Google rom Android 15 QPR2).
GrapheneOS I am
I have a Pixel 9 and have the issue.
Can confirm on a Pixel 9 with 2025030800.
One full power cycle fixed it, previous restarts did not.
kaiproctor Are the fingerprint options completely missing or does it just not work but the options are still present?
GrapheneOS fingerprint options completely missing
GrapheneOS changed the title to Workaround for very rare fingerprint firmware glitch with Android 15 QPR2 .
Can confirm, fingerprint options are completely missing after the most recent update on my Pixel 9. Multiple restarts and hard reboots have not resolved the issue. Fingerprint / biometric settings have also disappeared completely from the Security and privacy settings menu.
Another shutdown and boot solved the issue, thanks!
It's optimizing apps again.
Pixel 9, Build 2025030900
A further update, the latest reboot has seen fingerprint functionality disappear again... I will see if further shutdowns fix the issue again.
Lilac6044 Not sure if it is similar to yesterday, but further restarts have not returned functionality of fingerprint reader. It may return 'randomly' again, after a few more shutdowns. But it appears in my case that fingerprint functionality returning after shutting down the device yesterday was temporary.
Will drop a line here again if the reader starts working again. Many thanks.
In the morning, my phone suddenly heated up, and the alarm sound started stuttering at the same time. I saw a black screen with the message "Phone is shutting down," and at the top, there was a toast notification (I don't remember the exact text) saying something like "Fingerprint hardware not detected."
After that the p8 turned off. I let it cool down and after 20 minutes I put it on charge. It turned on with working fingerprint. This is very strange.This is the buggiest update I've ever received on a Pixel.
I had this issue with my pixel 9, I first waited a few hours for an "auto fix" as a few posts in this thread suggested, but it didn't happen. So, I had to reboot my pixel about 8 times in a row, and it fixed the issue. No issue since but I haven't reboot my pixel yet.
