I'd urge everyone here to seriously consider switching to GrapheneOS. It's a far simpler transition than e.g. switching from Windows or OSX to Linux, and many people find that it has basically no friction vs android.

More people moving to GrapheneOS is the best tool we have against Google's continued and escalating hostility to user freedom and privacy and general anti-competitive conduct. (Of course, you could ditch having a smartphone entirely..., but if you're willing to consider that you don't need me plugging an alternative).

Would but unfortunately I got screwed with a locked bootloader, either going to go the dumbphone or the (much less practical) cyberdeck + SIM card route.

This has really moved up my timeline of switching to Graphene.

Admittadly I was being lazy and not checking if Line works on it yet, but I'll be finding that out this weekend it seems.
