Block a phone number or contact on your Galaxy phone
If you're receiving spam calls or someone won't leave you alone, you can block their number. That way, their calls and text messages will no longer appear on your phone. You can also block and report calls with the Smart Call feature if your phone and carrier supports it. Plus, you can prevent callers from leaving voicemails by contacting your carrier.
Note: Available screens and settings may vary by wireless service provider, software version, and phone model. These instructions apply to Galaxy phones running Android 9.0 (Pie) or later.
Block numbers from the Contacts app
The Contacts app allows you to block unwanted numbers from contacting you.
Navigate to and open Contacts, and then tap the contact you wish to block. Tap More, and then tap Block contact. Tap Block to confirm.
Note: Even if you block a contact, they will still appear in your Contacts list.
Block numbers from the Phone app
You can also manually add a number to your Block list using the Phone app.
Navigate to and open the Phone app.
Tap More options (the three vertical dots), and then tap Settings.
Then, tap Block numbers. Tap Add phone number, and then enter the phone number you want to block.
Next, tap the Add icon (the plus sign) to register the contact to your Block list.
Note: You can also navigate to the Recents section in the Phone app, and tap the phone number you want to block. Tap Details, and then tap Block.
Unblock numbers or contacts
If you changed your mind, you can remove a number from your block list. There are two ways to do it.
Navigate to and open the Contacts app, and then tap the contact you wish to unblock.
Tap More, and then tap Unblock contact.
Alternatively, you can navigate to and open the Phone app. Tap More options (the three vertical dots), and then tap Settings.
Tap Block numbers, and then tap the Delete icon to remove the corresponding phone number from your block list.
Block numbers with Smart Call
Note: The Smart Call feature may not be available on all carriers, models, or software version.
Smart Call will recognize numbers that are not in your contact list and then give you the option to block or report the calls. This way, you won’t be bothered by them again.
Navigate to and open the Phone app, tap More options (the three vertical dots), and then tap Settings.
Tap Caller ID and spam protection, and then tap the switch to turn it on.
When your phone rings, the Block number and Report number options will appear at the bottom of the screen. Tap one of these options during or after the call if you do not want to be contacted by that caller again:
Tap Block number to add the number to your blocked call list.
Tap Report number if you feel the call is fraudulent, and then select a category, such as General Spam, Scam or Fraud, or Telemarketer. You can also include a comment when you report the number. Tap Report when you’re finished.
Navigate to and open Settings. Tap Apps, and then search for and select the Phone app.
Tap Storage, tap Clear data, and then tap OK to confirm.
Next, navigate to and open the Phone app. Tap More options (the three vertical dots).
Tap Settings, tap Caller ID and spam protection, and then tap the switch to turn it on again.
If you’re receiving an error message when using Smart Call, you can try checking for software updates. Navigate to Settings, tap Software update, and then tap Download and install. On certain carriers, you will need to tap System updates, and then tap Check for system updates instead.
You can also try clearing the data in the Phone app:
