How to Block a Number on Android

Jul. 6, 2024

You may want to block a number on Android for many reasons. Perhaps, scammers can’t seem to get enough from calling your number, or you no longer want to keep in touch with someone. The process of blocking a number on Android may differ depending on the manufacturer of your device. That’s why we’ve prepared multiple sets of instructions for phones from various brands in this read. Either way, blocking someone on Android is quite easy, and here’s how to do it.

Block a Number on Google Phones

Google’s Pixel devices come with the company’s own Phone app set as their default dialer app. You may also find this dialer present on phones from other manufacturers.

Note:Some brands like Nothing and Motorola also use Google’s Phone app as the default dialer app on all their devices. Only select models from OnePlus, Xiaomi, Redmi, POCO, OPPO, and Realme have this app set as default.

Automatically Block Potential Spam Calls

The Google Phone app has a feature that automatically blocks potential spam calls. It uses a database of reported spam callers to figure out if the number is spam.

Do note that this feature is a hit or miss (it misses most of the time) since Google’s database isn’t as comprehensive as, say, Truecaller’s.

Auto-Block Unknown Callers

While not a great solution, if you temporarily want to block all unknown callers on your phone, you could turn on the option to automatically block unknown callers.

This will block calls from phone numbers you don’t have in your contacts.

A toast “Added to blocklist” should appear once the number is successfully blocked.
