It's one of the big reasons I advocate for graphene even if one chooses to install Google services afterward.

Also notable: as of last year, OnePlus allowed mobile and WiFi network toggle, effectively doing the same thing.

For those of us stuck on normal android, is there a way to achieve that? I know it used to work with some firewall apps but nowdays they all require root access.

iOS allows this, but only on mobile data, which is pretty infuriating. Why should I not be able to also restrict apps from dialing home/anywhere just because I'm on a Wi-Fi network (which isn't even necessarily unmetered)?
