How To Block Unwanted Calls And Send Out Automated SMS Replies From Your Android Device

Considering the ease in which data can be obtained and shared, it’s not particularly hard to gather a person’s contact details for purpose of spam, harassment, or cold calls.

Neither Android nor iOS – the world’s two most popular mobile device platforms – offer much in terms of features for blocking or filtering prank, ad, or just generally unwanted correspondence. If someone (or some bot) is continually barraging your inbox or call log, there’s not really that much you can do, short of contacting your carrier and setting up a block remotely.

Going through all that trouble seems a little excessive, but there comes a time for most of us when we could do with blocking a number – if only temporarily – for whatever reason, and this is where apps like Root Call Blocker for Android steps into the fray.


As the name quite openly suggests, the app requires root access, but thereafter, provides a watertight blocking and filtering system for both calls and SMS. It operates silently, and the root daemon ensures blocking 100% of the time. You can opt to select whether or not you wish to be notified when a certain caller or number is blocked, and you can configure it to block those unknown and restricted numbers.

There are five reject methods in total, ranging from the basic "Don’t Answer" to the pre-meditated, automated SMS reply. The trial version allows you to add one item, although the Pro iteration costs five dollars, and offers unlimited access all of the features the app has to offer.

Another app to add to the growing list of reasons to root your Android, Root Call Blocker is the sort of app we only but wish could be a staple part of Google’s mobile OS at stock level. The chances of the Big G implementing such a feature-packed blocker to the end-user would seem speculative at best, but with such a good app already in our midst, there’s no need to tolerate the unwanted calls and messages anymore.
