In what is welcome news for vanilla Android users affected by spam and other unwanted calls, XDA-Developers is reporting on a number of new commits that allude to automatic blocking of questionable numbers, which include any numbers not in a contact list. Samsung phones have had this feature for some time.



Currently, you are only able to block calls on a per-number basis. The numbers that you block must be added manually, which means you basically can only block calls from unwanted numbers after-the-fact. With these new settings, however, you can restrict who is allowed to call you so you won’t ever be bothered by unwanted phone calls.
