@jj @Wetrix that might be too severe though. On Android you can (eg with NetGuard) cut off apps' Internet access completely, and between permissions and apps like Island you can restrict their access to your data.
(Personal experience: I need to have WeChat installed, which is even worse, but it effectively can't see anything on my phone, just what I send there)
@Wetrix @jj aren't you glad Google+ didn't take off then (or the Facebook phone flop from a few years ago).
But yeah, at some point I'm going to need to flash /e/ or Lineage on my phone, only way to avoid Google tracking. Right now it seems less bad to use Google Fi then using T-mobile though. We need a privacy-friendly MVNO
