How to Block a Number on Android

Calls are so accessible today that we can talk on the phone all day long. Therefore, our smartphones are daily broken from a huge number of incoming calls, and not every call is already a joy.

Some of the conversations you would like to miss, and some of the calls you want never to hear.
