To shutdown my GrapheneOSsed Pixel 6a I am pressing the upper button for a slightly longer period of time. For the most time I get a "box" (name?) with three or for circles and one of its says "Shutdown". Touching that one shutdowns the device. So fine so nice.
But from time to time I get a dialog, which asks me whether I want to boot into safe mode (which I don't).
What is the reason for this?
PS: Running the newest stable version of Graphene OS on a new Google Pixel 6a (without conduct).
Its still without a sim card...
