Amusingly LineageOS seems to support the S20 and the S22 but not yours!

I’ve been buying cheap used Pixels for the past few years (as in getting one, putting GrapheneOS on it, using it until it starts nagging me that it’s really definitely absolutely going to stop giving me security updates soon, and then looking around for deals on a newer old Pixel). GrapheneOS seems pretty good as something that gives you some good privacy and security while actually being usable as a daily driver, plus its absolutely trivial to install. If you’re feeling decadent you could wait for the supposed Motorola GrapheneOS phone next year instead, but there’s very little known about that.
