Whether it's a friend or stranger you don't want to hear from, knowing how to block a number on an Android phone is pretty useful.

Many of best phones available use Google's Android operating system, including many of our picks of the best android phones, so if you're thinking of shifting over to a non-Apple smartphone for the first time and want to master some of the basics, you're in the right spot.

If you're wanting to learn how to prevent a number from spam-texting or calling you, there are two methods you can follow, depending on if you've saved a number to your Contacts or not, and we've listed both of these methods below to help. It's worth noting different Android phones vary slightly in how the user interface is laid out, so don't be concerned if it doesn't look exactly the same – the steps here should still help you.
