How to Block a Caller on an Android Phone

When it comes to blocking unwanted calls on your Android phone, you have two options depending on how unwanted the call is. For serious offenders, the Black List feature on your Android phone is an excellent option, which allows you to completely block a call. For minor nuisances and other situations, it may be more appropriate to utilize the "Send Calls Directly to Voicemail" option.

Black List the Caller on Your Android Phone

If your Android phone allows, an option for completely blocking callers is to black list them. You can elect to black list a caller, which will send them straight to a busy signal. Keep in mind that you it takes a few minutes for this setting to take effect.

To black list a caller, press the "Menu" button, from the main screen. Then select "Settings" and then "Call Settings." Scroll to the bottom of the list and select "Black List." Click "Add Phone Number" and then you can either manually type in a phone number in the text box or you can click on the silhouette icon along the right of the text box and select an entry from your contact list. Click "OK" to finish.

Another way to add a number to your Black List is to hit the "Menu" button and then select "Add to Black List" when you are receiving a call from an unwanted caller. Keep in mind the caller will be immediately sent to voicemail. The next time they call, they will experience the busy signal.

To remove a black listed number, navigate back to the "Black List" screen and select the black listed number from your black list and click "OK."

Send Calls Directly to Voicemail on Your Android Phone

Navigate to your "Contacts" and select the contact you wish to send straight to voicemail. Press the "Menu" button and then click "Edit Contact." Scroll down to the bottom of the screen and select "Incoming Calls: Send Calls Directly to Voicemail." The caller will be sent directly to voicemail without the Android phone ringing.

This feature can be disabled by reversing the process.
