Junk calls have always been the bane of the phone users’ life; from the cold callers trying to flog you a conservatory to the recorded messages asking whether you’ve been mis-sold a loan. And now that more and more of us are using our mobiles as our main phone these kinds of calls are becoming not only inconvenient but intrusive as well.
There’s a relatively simple solution to this problem, and it involves downloading an app from the Google Play Store and setting it to deal with your unwanted callers. But most apps are fairly limited in their functionality and not always 100% reliable.
Root Call Blocker Pro, as its name implies, requires your phone to be rooted in order to function, which makes it significantly more powerful than a regular app for non-rooted devices.
With it you can blog individual numbers, or people from your contacts list (if you no longer wish to be pestered by them); you can block any number that is set to ‘private’ or unlisted; or you can go the whole hog and block entire area or country codes.
In addition you can create profiles that change the way the app functions depending on where you are or the time of day, for instance creating a ‘Holiday’ profile that only allows calls from an approved whitelist in order to minimise the number of calls you get on holiday without making yourself completely unavailable by turning your phone off.
Pick a profile
Open Root Call Blocker Pro and tap on the Profiles button on the bottom of the screen. This will show you a summary of all the profiles you’ve created and enable you to manage and build new ones.
Build your black list
Choose the Default profile to get up and running with the app. When you tap on it you’ll see a list of options including Black list setup – to choose numbers to block – and White list setup to choose numbers to allow. Tap on the Black list setup option.
Adding unwanted contacts
Now start adding numbers to block. Tap Add and choose from the list. You can enter numbers manually, pick contacts from your address book, add from logs (which will show you a list of numbers that have called you), or block those not in your contacts or listed as private or withheld.
Which way to block?
With your black list created press the back button then choose the Default blocking methods option. You can now pick how to reject a call. The best options are Reject, which simply blocks the call, or Don’t Answer, which will ring from the caller’s end but will do nothing on your phone.
Log those calls
Press back again and finally ensure that the Call Logging option is enabled, as it should be by default. This logs all the calls that are blocked and allows you to see how the profile is working, and also make sure numbers you want to let through aren’t being blocked.
Create more profiles
You can also create profiles based around calls you want to allow. Return to the Profiles screen, click the + button and add a name for a profile. Keep it as descriptive as possible so you will always be able to see exactly what it is doing.
Block all but a few calls
We’re going to base this profile around a white list of accepted callers, which means that all numbers not on the white list will be blocked. For obvious reasons this kind of profile should be used more sparingly and only for specific purposes.
Set up a white list
Tap your new Profile to start setting it up. Choose Operting Mode and select White list from the menu that opens. You can now start the process of adding your numbers, but this time only selecting the contacts that you want to allow through.
Add your numbers
Add numbers in the same way as in step 3, only this time choosing White list setup. For best results it’s a good idea to create groups of callers, eg Family, in your address book app. That way you can add them here in one go, and can easily add or remove people from that group in future.
Activate the service
With that done you’re now ready to use the app. Press the back button a few times until you get back to the main screen. Now tap the Settings button and tick both Enable call blocking and Start service on boot to activate it. By default blocked calls will appear in your notifications pane.
