I think the best way to detox is to get a smart watch with a data connection and just use that instead of your phone. You can do all the phone things but you cant use social media or the web. It’s kind of like having a flip phone. 

Sometimes I leave my phone at home, and just use my watch. I can get my insurance card, I can pay for things, I can text, I can listen to music and podcasts 

 Also I love custom ROMs on android 😁

More of a LineageOS guy myself, but my daily driver is an iPhone now.. Pixel 6 kept overheating even tho I degoogled it
