Hi
Does other than myself use app root call sms manager (works without root) or sim-blocker & call-blocker. I find them very useful, and they can block incoming call at specific time at day of sim card 1 or 2. Nice when you have free from work, and close for calls at sim 1, and sim 2 is still open for private calls, but they don't work after Android 10 update on Zenfone 6. I can read about sim issues, and it might have something to do with it, but my phone is useless without these functions.
This has been solved by new beta app from the maker of root call and manager 🙂
