I used a usb-c external SSD drive. Worked like a charm and I even could run starcitizen from that with no remarkable performance drop. Once I was settled with linux I just installed the external SSD internally.

Some other sideloaded apps work but everything with a map seems to be blocked. I had EV charging apps not show in Android auto.

Learned the hard way that android auto compatibility (on GrapheneOS) works only with the playstore Version of an app because andoid auto checks the install source. Thats the same gatekeeping at play…

Thanks I hate it.

I use backrest selfhostet on my server running yunohost. It is pretty much set and forget. I love it.
