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.

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.
