Call Blocking on Androids

Built-in call blocking features


Most Android phones allow you to block contacts directly through your phone. The procedure can be unique to your specific Android phone as it varies from phone to phone.

Voicemail redirection on Nexus 4


Although not exactly a call blocking feature, the voicemail redirection feature on the Nexus 4 can be used as a call blocker of some sort. To redirect calls to voicemail, just select a contact from the People app, open the Menu, and select All Calls to Voicemail.

Calls from the selected contact will now be directed to your voicemail box. Also, if you don’t have a voicemail subscription or you haven’t setup your voicemail properly, the phone will automatically reject calls from the redirected contacts.

Call barring on Xperia T, HTC One


On the Xperia T and HTC One, call blocking is known as Call Barring, which can be accessed on either phone’s Call Settings page on the Settings menu. Here you can block all outgoing calls, outgoing international calls, outgoing international roaming, all incoming calls, or incoming international roaming calls from everyone. You will need your barring passcode in order to activate these features.


On the HTC One, there is another way to block calls — through the Phone app. Just open the menu in the Phone app and select Blocked Contacts. Then, tap the Add button to add a contact to block. You can either add a contact from the People app or manually enter a number to block.

Call rejection on Optimus G


To block calls on the LG Optimus G, go to Settings > Call > Call Reject. From there you can enable the phone’s feature to reject all calls. You can also create a rejection list that only blocks calls from contacts included on the rejection list.

Reject List on Galaxy S4


Users of the Samsung Galaxy S4 can take advantage of the phone’s Reject List, which keeps a list of numbers that are blocked.

There are two ways to add a contact onto the Reject List. The easiest way is as follows:

  1. Open the contact’s page.
  2. Tap the Menu button.
  3. Select Add to Reject List.

The steps above will cause all of the selected contact’s numbers to be added to the Reject List. On the Contacts list, blocked numbers are shown with the blue universal “No” symbol.

If you need to block only some of the contact’s numbers, you can unblock the valid numbers through the Auto Reject List menu in the Phone app.


Another way to block contacts is to manually add numbers to the Reject List, as follows:

  1. Open the Phone app.
  2. Tap Call Settings.
  3. Tap Call Rejection.
  4. Tap Auto Reject List to open the list.
  5. Specify an exact number. You can also add numbers matching a search string that you specify. For example, you can add contact numbers that start or end with the digits that you provide, or includes the digits specified.

Blocking Mode on Galaxy S4


The Samsung Galaxy S4 also has the Blocking Mode feature, which lets you limit phone calls at certain hours. To enable Blocking Mode, go to Settings. Open the My Device page, tap the Blocking Mode option, and from there turn on the Blocking Mode switch. You can select what features to block. You can disable incoming calls, notifications, alarm and timer, and/or LED indicator.

When blocking calls in this way, all incoming calls will be automatically rejected and you will not hear any ring or feel any vibration when there is an incoming call, but you will see a notification of the missed call. If you want certain contacts to be able to reach you even if Blocking Mode is enabled, specify them in the list of Allowed Contacts.

Third-party apps for blocking phone calls

If your Android phone doesn’t have a built-in call blocking feature or if it does but you find it’s lacking, you can choose one from the many third-party call blocking apps on the Google Play Store. In particular note are the Mr. Number app, Call Blocker app, and Calls Blacklist app.
