Fairphone 6 turns off randomly from time to time

I don’t “fully” use it as a daily driver yet. I mean I somehow do .. most apps are installed, but I plan to check out another OS, as I usually run my phones without g-apps. Moving is not yet possible due to another small issue described here: Unable to unlock bootloader, IMEI not recognized - #13 by Smojo

Anyway right now it runs the StockROM, but no google-account connected so far.

Long story short: If the random “turn off-s” pop up here as well, I’m ok with re-installing or whatever is needed (as I want to do that anyway).

The old FP5 is also still available or at least accessible, even in a kind of untypical state ^^
