Since some weeks my fingerprint is not working stably.
I followed advice from https://discuss.grapheneos.org/d/20636-workaround-for-android-15-qpr2-fingerprint-firmware-glitch-on-pixel-9/84 and powered off many times.
The fingerprint appeared again only to be lost after the next reboot/poweroff (which happened often due to the high number of incoming updates at the moment).
Any other ideas?
