Android’s Contact application allows you to set up auto-reject of incoming calls on a per-contact basis. But that’s the extent of
the built-in abilities. For users who want a bit more incoming call
control, there are apps on the Google Play Store that handle call blocking. One
such tool is Call Blocker by NQ Mobile Security.
Call Blocker is a free app that offers enough features to
satisfy nearly any user:
- Block unwanted calls (reject, forward, or reply
with an auto-SMS)
- Block spam SMS (accept phonebook only or simply
- Back up contacts to a server
- Transfer data to new phone (Symbian, Android, or
- Quickly and easily erase the call history and delete SMS messages between your phone and individual contacts permanently
- Auto-detect of one-ring malicious calls
The above features are available on the free version, but it includes an unobtrusive ad bar. There’s also a premium version of this app with additional features, but it costs $1.99 for one
month, $6.99 for six months, or $12.99 for one year. Here are some of the premium features:
- Removal of ad bar
- Private space (hide specific messages and call
logs to a private space)
- Conceal private space icon
- Create “fake” private space
- Hide calls from private contacts
Let’s go ahead and install of this app and then walk
through its usage.
Follow these steps to install Call Blocker.
- Open the Google Play Store

Once it’s installed, you’ll find the launcher for the app in
you app drawer and/or on your home screen. Tap that launcher to open Call
From the Call Blocker main screen (Figure B), the
first thing you’ll want to do is configure how Call Blocker works. To do
this, tap the menu button, and then tap Settings.

From the Settings window (Figure C), set up the Call Blocking Rule (indicating which contacts will be blocked). You can
block by: Blacklist, non-contacts, non-whitelist, all, or none.

The most effective way to block calls is by using the
Blacklist. Of course, this means you have to actually create a blacklist of
numbers. To create a blacklist, do the following:
the main window, tap Blacklist
from the options (Figure D)
manually input the number or locate the number from Contacts or call/SMS logs
Adding a number to your blacklist.
When that newly added number calls in, you’ll receive a
notification of the call, but the caller will be treated with either an
immediate pickup/hangup or close ringtone. The close ringtone will allow the
call to go through, but you won’t hear the ringtone (no matter what the
volume is set to). The close ringtone option will also allow you to answer the
phone call — so, for a true blocking option, select Pickup/Hangup from within the
How to block calls option in the Settings window.
Finally, you might want to set up a response to callers.
The response will come in the form of an immediate text once the call is
blocked. To set the response, follow these steps:
- Go to the Settings window
- Tap to enable Response to caller
- Tap the Choose a message option
- Either select the auto-response message or create your own
by tapping Create new reply message (Figure E)

The ability to block unwanted incoming calls and SMS messages has become more of a necessity than a bell and/or whistle. Even though
the Android platform allows you to block unwanted calls, it doesn’t offer
enough features for everyone. Give Call Blocker a try, and see if it doesn’t
take care of blocking those pesky calls and SMS messages.
