Nuisance calls are one of the modern evils of the world. Whether it’s sales, marketing, or just plain old people you don’t like, having your phone ring at all hours only to find these unwanted interlopers interrupting your day is no fun at all. Of course, if you’re in the UK, you can sign up to the Telephone Preference Service, which does its best to stop unwanted calls, but some of the more persistent offenders often manage to sneak through. So what can you do on your Android phone to stop the madness? In this feature we’ll take a look at the options open to you, and hopefully return your life to the peaceful, robot-salespersonless way it was meant to be.

How to block a number on Android: Block calls in Android

There are three main options for blocking a number in Android:

• Contact your mobile operator

• Check your Settings menu for an auto-reject list

There are some phones that don’t allow the feature directly, and in those cases you can use third party solutions, a couple of which we’ve also included in our guide.

How to block a number on Android: Using third-party solutions to block calls in Android

While the above manufacturers have made it quite simple to rid yourself of annoying telemarketers and their ilk, several others have omitted this option from their platforms. Google’s Nexus range only allows you to send callers directly to voicemail, but this isn’t really a solution, especially if you actually use your voicemail. Thankfully, when you can’t block callers from your phone’s OS you can still turn to third-party solutions. If you use anti-virus software on your phone, such as Avast, then you’ll find the feature often included in the service. Otherwise you can download dedicated apps such as Truecaller or Mr Number which provide the same kind of solutions as those on the phones listed above.
