GrapheneOS if it matters: point 3 in the update changes happens on my phone quite often. But it happens on the pixel7a. When this happens, I can not type any password characters into the password prompt. A reboot is the only solution that work for me. (Also I tryed to re-trigger the PW prompt by re-pressing the power button bit this did not work). I don't know if it's true, but it seems to me that this bug is more likely to appear if I don't touch the phone for about 10-15 seconds after reboot.
I did an update to the version 2025032100 today.
I will make another comment if the bug is fixed or not.
