The new spam call use a group of calling number instead a single calling number.
This mean for example the spam caller number is not an exact number like +37731234567. It use a group of numbers (typical 1000 number) for example in range from +37731234000 to +37731234999, and each call spam use a different caller number.
To block it need a wildcard on a call blocking feature.
But unfortunately this is not works on Galaxy A70 (works in any galaxy?).
Without this the phone ring more times in a night because the spam.
