@stefano Same / similar setup I have currently. I own the Google Pixel 7 Pro and have instsalled GrapheneOS on it 1.5y ago, Love it.
Main profile: Completely de-googled, with F-Droid/Aurora.
Google profile: Some apps I sometimes have to use but require (sandboxed) Google Play
Social Media profile: For Mastodon, LinkedIn, Reddit, Facebook...
Data sync with my home FreeBSD based NAS: Syncthing
. I have blogged about it last year: https://foo.zone/gemfeed/2023-01-23-why-grapheneos-rox.html (Didn't use Syncthing back then)
@stefano Not all banking apps work on GrapheneOS, even with Sandboxed Google Play services, though. For one bank, it works for me. For the other bank, it doesn't. So I still have to have a stock-android phone for this exception. But I am not banking all the time, so the stock-android phone stays home in my shelf.
