I personally observe with my own eyes many many times where Android turns off Adguard's VPN for a split second when doing various Google things like receiving messages in Google Messages.
I haven't been able to pinpoint it but my observation is that the disconnect/reconnect happens when a connection is trying to be made (ex. RCS message incoming), and I suspect Android is dropping the VPN to make its own connection. Sounds paranoid, but I've been carefully watching it happen for a long while.

Same with sensors, camera and microphone. Core system services will always have the privilege to override your permissions.
Developer Options allow you to fully(?) disable these, but even then, your dialer app for example will have perfect access to your microphone.
Don't get me wrong, I'd rather have it be like that in case of an emergency, but it does make you think.
