Howdy. Just telling my story incase it's useful to someone.
I've been on GOS for about 6 months. I was originally looking for a dumb phone to minimise my digital-ness then stumbled upon GOS. I already had a Pixel 6 so I DL'd it and off I went. I went full James Bond no Google VPN out the wazoo. It was great! In the little country town where I live it was perfect, no complaints. However I also travel from time to time with work and I found when I was moving around domestically and internationally, I missed the creature comforts. So in the end I've stayed with GOS but run it full google. Have all the google apps back, I'm signed into everything.. zero fucks so to speak. The only thing I've done is taken the network settings off Gboard (and anything else I feel is unnecessary), and my finance apps are in a separate profile with a VPN. Sandboxed Google Play works a treat. Just wanted to let people know who are thinking about it but aren't sure whether the transition will be easy. I found it seamless. I still can't get Texty to work on my Macbook but that's ok. Also no cards in Google wallet but I'm ok with that too. I realise I'm sacrificing privacy by using it this way but my threat level is pretty non existent. I figure I'm at least limiting Google's stranglehold on my life a tiny bit by running GOS. I'm about to embark on a big trip to Brasil so I'll see how I go over there!
