Hi @Chinaski , yes. The reboot is gone when i disabled adguard. So now i'm not using the app, temporarily using adguard dns.
Since realme 3 pro made android 10 available. Around January 2020, and then i followed this thread and github. there are 2 updates after this, but they're for security not the android itself. So what have been discussed here is not applicable. that's why i made post here.
