Since Waydroid is using Linage you can still limit what the apps and services in the Android OS, such as Google Services, can access.
Ive also noticed that both F-droid and Play Store auto updates when Waydroid is running, however
they can lock up when booting Waydroid freshly since they seem to complain about time not being correct.
I might be forced to use waydroid since my country have apps I need that only exists on iOS or Android. So this Topic is very relevant for me as in needing setup waydroid and make it a dev device
since Waydroid is not certified ( Waydroid: Google Play Certification )
