WiredMonk sometimes my phone will say "Updating phone" and it will update/optimize every app on the phone.
This is expected after an update.
WiredMonk I don't understand how this works. I haven't logged in to my owner profile yet, and not even got passed unlocking the sim, but the phone can reach my apps? How is this possible?
Apps aren't actually stored in any profiles, so they're not encrypted. The data that the apps save for personalization (like login info, etc.) is encrypted, though. In depth information about how encryption works on GrapheneOS can be found here: https://grapheneos.org/faq#encryption
So, since the apps aren't encrypted, no login is necessary for the phone to have access to and to be able to "optimize" apps.
