How to Block Unknown Callers on Android

With a modern world that is heavily reliant on mobile communications, it’s got to the point where you’re virtually contactable. The problem with friends or relatives calling is not the issue, rather it’s the callers that you don’t know, want to know or simply have not got the time to talk to. While you can turn off your phone to stop people calling you, there is still no escape as you still have voice mail and text messages, and you may need to leave your phone on if you’re waiting for a call from someone you do know.

Many modern phones, like the ones blessed with Android 2.2 or above, have a simple option available to them in the Settings, which can add callers to a blacklist. However, if you want a bit more control than this option offers, there is no choice but to install a third-party solution from the Android Market… but don’t worry, as there are plenty of apps available that deal with this issue.

We take a look at one such app called Call Guard. This has a fair amount of functionality on board, such as SMS blocking, call blocking (both incoming/outgoing) and filtered blocking. This last option enables you to custom define what happens to your received calls on certain times and days of the week.

How to Block Unknown Callers

If you’re fed up of receiving calls from total strangers, you can take control back with a third-party app named Call Guard

1: Download and install
Head to the Market, search for Call Guard and press the Go button. Find the app (it’s the fifth one down in the shot above), install it to your phone and then launch the software.

2: Block contact(s)
Select Filters and then press Menu followed by Add. Enter an appropriate title and use the drop-down box to select the actions that are ticked above.

3: Filter incoming
Next press the Incoming icon at the top. Place a tick next to Block from black list and select the adjacent arrow. Press Menu and select Phone book.

4: Filter icons
Select the contacts you want to block and you’ll then be returned to the screen with your contacts displayed and two small icons next to the name.

5: View blocked calls
If the person in your filter list calls they will be blocked and an SMS will be sent out to them. However, to view the blocked call, select Blocked Calls.

6: Block global preferences
You can also block numbers on a global scale. Select Settings then Block Preferences. Select an action, now scroll down to Block Incoming calls.

7: Block global incoming
Tick ‘Block unknown incoming and hidden incoming’. This will stop private numbers and anyone who is not in your phonebook from getting through to you.

8: Blocked Call notifications
Scroll to the Blocked Call notification options and then select the Notification text. Type in your preferred words and press the Back key to finish.

9: Password and start settings
While in the Settings, head to the top of the list, tick Start on boot and then enable a password via the Password protection box lower down in the options.
