Is there a support group or discord for degooglers? I did it a month or so ago and am still dealing with the ramifications. Most recently I used App Warden to disable all the spyware libs (including Google's) shipped with WeChat. They detected this, and banned my 10 year old account with all my friends and relatives. Been struggling for two days trying to get it reactivated, cuz it will be extremely difficult to travel back to China without it. I am not blind to the irony of keeping Tencent on my phone as I remove Google.
What would be really helpful is a database of apps, similar to the WINE project, maintaining how well they work on a de-googled phone, with a table, columns being "no root", "rooted", "with microg", etc, and a WINE style rating of how well it works and what problems you'll run in to.
You would know which banking services, etc don't work well or at all and could choose your establishments with foresight.
