My OP6T has 128GB internal no SD. The Moto G7+ has 64GB internal and up to 256 SD. I love both phones. My only gripe with the 6T is the on screen fingerprint reader, its finicky. Not the case on the Moto, it works good as the Galaxy’s. OP has great specs, Moto more mid tier specs.
Have you ever looked at running a Plex or Kodi server (can be done from a home lap or desktop) for your music? Then you could sandbox the app in Shelter or ensure NextDNS is blocking it’s trackers? The Plexamp app is great for streaming music.
Another option might be to install Lineage for microG until /e/ releases your OP Nord 10, 5G (if its supported, is it?) Granted LOS for microG will phone home to Foogle more but its still better than OxygenOS.
@Taurus uses a Sony I believe. I run a Sony Xperia XZ3 for testing other ROMs and its a nice phone (no /e/ support).
Interested in what @Taurus has to say as he is full of info!
Also others, would love some dialogue.
