Blocking incoming annoying messages can be enabled in Android 4.4.4 KitKat by blacklisting the contacts. It has the same procedure as those of incoming calls but the difference is that of messages only.
Anyhow, this is a simple process and can be achieved by a few steps. Just follow the instructions.
Command Line: Messaging App > Settings menu > Settings > Blacklist – EXTRA SETTINGS > ON/OFF.
2: At the ‘Messaging’ screen, tap the ‘Settings’ button, available at the top right corner of the ‘Messaging’ screen. It will open up a popup menu.
4: At the ‘Settings’ screen, see the status of ‘Blacklist’ under the EXTRA SETTINGS. It is ‘Disabled’. Tapping it will open up ‘Blacklist’ screen. 5: Here, again see the ‘Blacklist’ switch is OFF. Tap it to ON, i.e. activate it. Now, you may add contact numbers which you want to block by blacklisting.
Now, you may add phone contact numbers in the blacklist to block messaging from these contacts numbers.
