Unknown numbers are blocked automatically

Hello

I own a mx4 pro with flyme 4.2.2.1 A.
Recently I recognized that all phone calls with unknown or private numbers are being blocked even though the function are not activated.

Any ideas what is wrong?

Looks like a firmware issue. However, this behaviour could be caused by 3rd party apps too, e.g. phone blocker or whatever.

If you are sure not to own such apps reinstall the firmware with clearing data.

Reinstalled a new firmware and the problem disappeared!
Thanks for the tips
