Kalimera. Greek and GrapheneOS (Pixel 8a) user here. I don’t use these apps on my GrapheneOS device on a daily basis. I usually have them installed on my iPhone. However, after a quick installation and test, they seem to function well without any issues. I can log in with my TAXISnet and Piraeus Bank credentials and navigate the menus without crashes.
The Piraeus app will crash if all app exploit-protection settings are enabled. It appears that if you 1) allow DCL via memory and 2) disable memory tagging, the Piraeus app stops crashing. However, I can’t get biometrics to work in the Piraeus app.
It’s important to note that I tested this in my Private space with Google Play Services installed there, as my owner profile is Google Play Services free. It could be an issue specific to the Private space, but I’m not entirely sure.
See attached pictures for proof of functionality.
