Some of the Android devices are purchased just to use for the private communication and the undue interference, like the calls or messages from the numbers unknown to the device, are not liked. Some people do not like the calls from the numbers not in the contact list. In Android devices, a feature has been added in order to preserve your privacy and to block calls or messages from the numbers which are not in the contact list of the receiving device.
You may also add such numbers but if you feel any problem in this regard, you may consult instructions.
