How To: Block Unwanted Calls On Android



A quick guide on how to block unwanted calls on your Android device.

Cellular phones have been making it easier and easier to get a hold of friends, family, co-workers, and just about anyone else you’d like to get a hold of and with smartphones it makes it even more convenient, with being able to add pictures, addresses, along with other information to your contact book to help identify the caller. Though it’s great that we are more easily able to stay connected to those around us, many of us still struggle with the age old telemarketer or undesirable calls, or maybe it’s just someone from a previous relationship you’d rather not speak to, whatever the case most of us have a list of people and businesses that we’d rather not get calls from.

Today, Android devices make it easier than ever to create a black-list of phone numbers that we don’t want reaching us. Most Android devices even allow for additional blacklist options like sending the call directly to voicemail or straight-up blocking the call.  Android devices will typically have a basic built-in feature to allow you to create a blacklist of callers, but what if you’re looking for a more robust way to manage what calls come through your device? Well, that’s not a issue either as there are plenty of apps out there to help manage calls further. We’re going to cover both methods, first a general overview of blocking calls with the built-in Android feature, then we’ll cover just a few of the apps that further manage calls on your device.

Built-In Call Blocking Feature

First off, it’s important to note that even though most Android devices support this feature, the means to access the feature can differ from phone to phone. Most of the means to accessing the block caller feature are quite similar, so we’ll cover some of the more popular Android models and if your device isn’t on the list, then hopefully it will give you enough insight to find the feature on your device. If all else fails, just leave a comment below and we’ll do our best to dig up the answer you’re looking for.

Samsung Galaxy S4


The Galaxy S4 uses a Reject List to manage what incoming phone numbers should be blocked. You can easily add or remove a contact from the Reject List with the following methods.

  1. Open the contact’s page
  2. Select the Menu option
  3. Choose to “Add to reject list”

This will add the entire contact to the reject list, if you’re looking to only block a certain number from the contact, you can go into the reject list and remove any specific numbers you want to allow through. You can also add specific numbers to the reject list by using the following steps.

  1. Open the Phone app
  2. Select the Menu option
  3. Select Call Settings
  4. Select Call Rejection
  5. Select the Auto Reject List option
  6. Specify the number you want to add or select the number you want to remove from the list.

The Galaxy S4 also has a call blocking mode to allow incoming calls to only come through at certain hours of the day. This is a great feature for anyone who get annoyed by phone calls during work hours, dinner hour, sleeping, etc. To enable Blocking Mode, just use the following steps.

  1. Select Settings
  2. Open the My Device page
  3. Select Blocking Mode
  4. Flip the switch to enable Blocking Mode

You can also exempt certain numbers from being rejected from Blocking Mode, you just need to add them to the list of Allowed Contacts.

Nexus 4


The Nexus 4 does not offer a call blocker, but it does give the option to redirect certain callers to voicemail. With most devices having the option to use a visual voice mail app, it makes it dispatching unwanted voice mails easily, making the redirect option a good work around for blocking unwanted calls.

  1. Select Contact you wish to have redirected to VM
  2. Open the Menu
  3. Select All Calls to Voicemail.

If by chance you do not have a voicemail box setup, the feature will then actually reject the calls. I personally like this feature, because some callers I don’t necessarily want to block completely, I just don’t want them blowing up my phone at any given time.

HTC One & Xperia T


Both the HTC One and the Xperia T offer a feature called Call Barring, which acts as a call blocking feature.The Call Barring feature allows you to block all outgoing and incoming international calls, roaming, and calls from everyone. You will need a Barring passcode in order to activate and deactivate this feature. You can access the Call Barring feature either in Call Settings or the mail Settings Menu.

The HTC One offers a additional call blocking feature, that will allow you to create a blacklist with particular contacts to block.

  1. Open the Phone App
  2. Open the Menu option
  3. Select Blocked Contacts
  4. Use the Add button to add a contact to your block list.

The block list gives you the option of adding either contacts from your phone book or entering a specific phone number to block.

Third Party Call-Blocking Apps

Of course if you have a phone that doesn’t support a call blocking feature or you’re just looking for a more robust approach to call blocking, there are plenty of options when it comes to third party apps to block calls. There’s plenty of options out there and of course the choice is always yours on which app to use, but here are a couple of good call blocking apps that we’ve found, that are worth checking out.

Call Blocker


Call Blocker is a useful call blocking app that is free to use and is supported by the use of ads. You do have the option to subscribe to the paid version, which will eliminate all ads used with the app. The paid version also comes with some premium features like Private Space, which securely stores private call logs and SMS messages.

Here are some of the main features with Call Blocker

  • Black list
  • Block unwanted calls (Reject calls or automated reply with auto-SMS)
  • Block spam SMS (accepts only phone book or uses black list)
  • Contact Backup
  • Transfer Contacts to another phone
  • Privacy Eraser
  • And More..

Making use of Call Blocker is fairly simple, download the app from the Play Store, open the app and select the Blocked Calls button, from there you can add any number or contact to your blacklist.

Calls Blacklist


This is another call blocking app that is free to download and is supported with ads. You can purchase the premium version of the app to remove the ads as well.

Calls Blacklist is a simple app that keeps a blacklist of contacts you don’t want to allow to contact your phone. Using the app is as simple as opening Calls Blacklist, adding a number via contacts, calls logs, entering a number manually, and even SMS-Messaging logs. Once the number is on the blacklist, you won’t have to worry about another call or message from that contact.

Last but not the least on our list is the free and ad-supported Calls Blacklist, a very simple app for keeping a list of contacts that you don’t want to allow to contact your phone. An ad-free premium version is also available for about US$3.00.

To block calls with Calls Blacklist, just launch the app and add a contact number to the Blacklist tab. You can add a number via your Contacts, call logs, or messages log, or add numbers manually. And, that’s it! Contacts saved under Blacklist won’t be able to call your Android phone anymore.
