Block a phone number on your Android phone

For: Android phone, including Samsung Galaxy

Last checked October 14, 2026 against official help from Google and Samsung. Written for Phone by Google app and the Samsung Phone app.

If one number won't leave you alone, you can block it. Your phone turns down calls from that number on its own.

This page is for you if

  • The same number keeps calling you
  • Someone you don't want to hear from keeps calling

Good to know first

Pixel and many other phones use the Phone by Google app. Samsung phones use Samsung's own Phone app, which has its own steps. Menus can also differ by carrier and software version.

Do these steps

  1. Open your call history

    Open the Phone app. Tap More (three dots), then Call history.

  2. Tap the call

    Tap a call from the number you want to block.

  3. Block it

    Tap Block / report spam, then confirm. You can choose whether to report the number as spam too.

On a Samsung Galaxy phone

  1. Open Recents

    Open the Phone app and tap Recents.

  2. Block the number

    Tap the number. Tap Menu (three lines with dots), then Block. Tap Block again to confirm.

  3. Or type the number in

    In the Phone app, tap More options (three dots), then Settings, then Block numbers. Type the number and tap Add (the plus sign).

Good to know

  • To unblock a number in the Phone by Google app, tap More, Settings, then Blocked numbers. Next to the number, tap Clear, then Unblock. On a Samsung, go to Settings, Block numbers in the Phone app and tap the red minus sign next to the number.
  • In the Phone by Google app, blocked callers can't leave voicemail if visual voicemail is on.
  • Scammers switch numbers often, so blocking one number won't stop them all. To filter out likely spam, see how to stop spam calls on Android.
