I would also suggest looking into GrapheneOS if you’re looking for something new. I’ve been running it for 6 months on my pixel 6, and I have really enjoyed it. Apps just work, you can still use Google Play services in a sandbox, it’s smooth and gets good battery life. The only downside that I have run across is the lack of Android auto support, but everything else just works
Yes! It runs on an old gaming PC for me, without flaws
