I have a Motorola G7 Power that I installed LineageOS on. It was kind of hard to do, but I figured it out finally after some trial and error. If you ever wanted to do something similar and need help, let me know. I feel more comfortable having this versus a googled Android phone, and it is customizable enough that you could dumb it down.
GrapheneOS seems like an ideal choice, but I hate Google and didn’t want to risk buying a used phone off of eBay that was carrier locked. Most people I’ve seen recommend buying an OEM unlocked Pixel new from a store, which I would hate doing. Let Google starve. I feel like Google and Amazon are huge instigators of the social problems around this.
I’m still trying to figure this out for myself.
You just need to put yourself around people as much as possible.
If your circumstances are that it isn’t possible, you shouldn’t beat yourself up about it. You perhaps could then make it your goal to relocate or put yourself in a position where you can be around people.
What kind of stuff are you into?
