How to block calls on your Android phone

Update: Use Google Dialer to block calls in Nougat

There are plenty of occasions where you might want to block calls from certain numbers. It could be an insurance company trying to make you claim compensation for that accident you never had, or a possessive ex-girlfriend or boyfriend. Whatever your reasons, we can show you how to block calls on your Android phone, whether it's an HTC, LG, Samsung, Sony or other Android device.

Google Dialer

Thanks to Google, you can now block spam callers with Google Dialer - but only if you own a Nexus or Google Pixel Device. The Dialer app was briefly available for a host of other Android devices but google said that this was a mistake and quickly patched the app. Even if you download the APK, your phone will still refuse to install the app. If you do not have a Nexus or a Google Pixel you will sadly have to wait until the app is available for all Android phones. 

If you haven't already done so, you'll need to install the app first. Once you are done, you'll soon find that this is one of the easiest ways to block numbers from your device. To block any number, just follow these simple steps:

  1. Launch Google Dialer
  2. Tap on the menu button next to the microphone icon in the margin at the top of the app
  3. Tap Settings
  4. Next, tap Call blocking
  5. Tap Add a number
  6. Enter the number you want to block.

You can also block numbers by just selecting them from your recent calls list. Just select the number and select Block/report spam. Once you do this, you'll never hear from that annoying caller again. Reporting the number will also send it through to Google and other carriers, which will enable them to develop more effective spam filters in the future. 

Samsung (Galaxy S4, S5, S6, Note 4)

To block all calls from an individual on your Samsung Lollipop device:

  1. Tap the Phone app, Call Log, then the number you want to block.
  2. Next, tap More at the top right, then Add to auto reject list.
  3. That's it! To reverse this, just go through the same process again but tap Remove from auto reject list at the end.

But there's more. You can also manage your auto-reject list and even block unknown numbers:

  1. In the Phone app, tap More at the top right, then Settings.
  2. Next, tap Call rejection > Auto reject list and you can see all the numbers you auto-reject.
  3. Here you can manually remove and add numbers to the list, or block all unknown numbers by toggling the switch next to Unknown.

Stock Android (Nexus 5, Nexus 6, Moto X, Moto G)

Oddly, neither stock Android Lollipop nor Marshmallow has an integrated call-blocking feature. Instead, whether or not you have call blocking will depend on your carrier. To check if you have it, open the Phone app, tap the number you want to block, then tap Details, and then the Menu button at the top right. If your carrier's included phone blocking, it will appear here as Add to blacklist or Reject call.

There is a workaround for Lollipop or Marshmallow users though, albeit not an ideal one (this process is essentially the same for KitKat too).

  1. First, save the number you want to block as a contact.
  2. Next, go to your Phone app, tap Contacts, then tap their name.
  3. Tap the pencil icon next to the menu icon, then on the next screen tap the menu icon at the top right and All calls to voicemail.

Alternatively, you could install an app that lets you block calls and manage them. Calls Blacklist is a call-blocker with a good reputation, and will do the job stock Marshmallow can't.

HTC (One M7, One M8, One M9)

Like Samsung, HTC has made it super-easy to block calls, and easily manage your blocked numbers. To block calls from a specific number on your HTC phone:

  1. Go to your Phone app, then go to Call History or tap the search icon to find the number you want to block.
  2. Long-tap the number you want to block, then tap Block caller.
  3. To manage your blocked contacts, tap the menu icon at the top right of your Phone app, then Blocked contacts. Here you can add or remove blocked contacts, and even see when your phone blocked messages and calls from this contact.

Sony (Xperia Z2, Xperia Z3, Xperia Z3 Compact)

The Xperia Z series doesn't feature in-built call blocking, so you'll have to use the Lollipop solution to block numbers; either download Calls Blacklist or send unwanted numbers straight to voicemail. To do this:

  1. Tap All apps > Contacts then the name of the contact you want to block (if the number you want to block isn't already a contact, you'll have to make it one).
  2. Once you've tapped the name of the contact, tap the Edit icon, then Menu, then All calls to voicemail

LG (G2, G3, G4)

LG phones have some nifty tools for blocking numbers – a little too nifty perhaps. If your LG is running on Lollipop and you receive a call from a number you want to block, rather than sliding your finger from the center towards the red phone icon, drag the red phone icon into the center instead. This will add the caller to your 'Call reject list'. To manage this list:

  1. Go to Settings > Wireless and networks > Call.
  2. Next, tap Call reject > Reject calls from to see your list of blocked numbers. You can add numbers to this list by tapping the '+' icon at the top right, or remove them from this list. You can also reject all calls from unknown ('private') numbers here.

  • Any reason it says my device is not compatible with google dialer? A galaxy 7?

      Hey Susan, a line was missing from the Google Dialer section (which has been fixed now) - the app is currently only available for Nexus and Pixel devices.

  • Great article and glad you are helping out, it's a shame and I'm puzzled as to why Sony don't have in an built call blocker, one of the reasons I didn't bother with a Sony phone, didn't want to have to download yet another app.

  • ok thanks for the call blocker app.but what about that annoying sms messages from call centres and cell phone companies how do i block that numbers?

  • I like the apps that combine phone and SMS blocking and also have the option to simply restrict incoming to my contact list, insted of blocking after some bloody nuisance has already bothered me and then changes his address to do it again. Also want call details recorded just in case it's a good one. Vlad Lee's "Calls Blacklist" does all these well - as usual you have to use the blocker app to replace the SMS app, but it's a pretty attractive one.

    My experience has been that nuisance communications usually dry up after a few days with the blocker, so it's not normally on. If I was better looking I might have more harassers to deal with.

  • I can tell you a sure fire method. Instal Kaspersky Internet Security for Android. Add the numbers you wish to block under the option Call & Text Filter. You won't be bothered again. Works on all Android phones. The only downside is that you won't even know if the blocked number has called or not. But in most cases, admittedly, it's more peaceful not to know.
    One more thing, what's this Google Dialer? I couldn't find any such thing on the Play Store.

  • I use true caller no need to add numbers it blocks all unwanted calls

  • storm Mar 13, 2017 Link to comment

    The app Mr. Number is very useful for blocking calls. Crowdd sources Robo call identifications and more.
    Use Google voice and white list the numbers that can call you. You've already built the contacts database, put it to work for you.

    Overall complete guide to block calls for specific mobile phone brands and very helpful topic. Thank you.

  • Hi…I own a Moto G (3rd Gen) , currently if anyone is calling after one ring it says that the number you are calling is busy and I get no notification as missed call or something. Also the drop down menu for notification which shows settings, update on various apps is also not reflecting. Could you please help??

  • thanks a lot , i blocked successfully . By doing this can we block messages too that blocked number or not ?

  • Call to vicemail feature works but on kitkat it always show notification when someone blocked (like missed call). But now on lollipop there is no notification when someone is blocked O.O is this something new on lollipop or is there something wrong??? Also why is it call to "voicemail" when for the blocked contacts it ring once and than it say that number is not answering (no redirection to voicemail)? Voicemail work normaly when phone is turned off.

    How do u send a particular caller directly to voicemail but still get their texts? Htc1

  • I don't have the option on my LG G4 to block calls and texts!! Someone please HELP!!

  • Top apps can’t be developed newcomers. They may code it but can’t build enterprise ready app. You must find a company with more than 5 years of experience in developing the business apps. In India, top android app development companies are delivering next in class apps to global clients.

  • Razorfoot Nov 30, 2015 Link to comment

    Thanks, now i will make a zBlock contact and dump every spam number that keeps flooding me with lost calls.

  • Blocking calls is also important if there are unwanted calls and people you want to get rid of. Thank you for sharing that information.

  • How do you block with a Samsung S5 running Kitkat?

  • I miss being able to reject a call and on their end it kept ringing then to vmail so they don't know you just rejected them.

  • The article's instructions are incorrect for the LG G4.
