I have "Network" permission from every app i have access to except for Tor Browser. Currently "Android OS" app is in Non-Carrier data usage page, when i click on it, i am redirected to Dynamic System Update app settings. I have separate non-owner profile with Tor Browser app in it with no system wide killswitch configured, also i have system update app enabled in "Owner" profile, that "Owner" profile has system wide killswitch with Orbot configured. I fear that ISP will figure out that i am using GrapheneOS because it makes connection to server specific to GrapheneOS. Is that true that it is still making those connections? And if true, what should i do to avoid that in GrapheneOS or should i use different ROM?
