You are making me remember ancient history @Catfriend1. 😄 It’s been a long time since I looked into such issues, but back then (few or more years ago) at least I seem to recall ~ that the VPN on Android is not leak proof. There is some brief time at the beginning where some stuff can still leak out, before the VPN firewall goes into effect.

Android in general is a mess, and for someone like me used to a real operating system (GNU/Linux) Android is like a toy in comparison. Real, actual, GNU/Linux phones like Pinephone and/or Librem 5 cannot get here fast enough, IMO. Luckily, we are finally seeing some nice movement on this front. Android and iOS desperately need some competition.

But other than these sort of potential “leaks” I think the intention is for that feature to block everything except traffic going over VPN, which was what I was trying to suggest. Maybe that is/was the problem (I could also simply be wrong)?

Last time I made an audit log, Android connected to my phone manufacturers “spyware” servers during boot and then went silent as soon the vpn came up. This was with Netguard VPN back then.
