Hi Ben, I recently set up GrapheneOS on a google pixel pro9 by myself, still learning and hoping i now have a full privacy phone (sandboxed applications)
Google play store however is still required for all banking related apps like: ledger live, Revolut, Envoy, Muun, Wallet of Satoshi, also Bitwarden app is a requirement but not sure if it is a “safe” option using a paswoord manager on GrapheneOS
This is one profile, another profile still uses google apps like whatsapp, youtube, waze, translate, telegram, signal…
Next i still want to check out what would be best is a sim or esim for one or both profiles, at the moment i use wifi connections for the different profiles (North VPN-Tunnelbear)
Looking forward to your tutorial on GrapheneOS
