Knowing how to block a phone number on Android will certainly prove useful if you're constantly receiving spam and promotional text messages or calls from an unwanted person,

As of right now, Android is the most-used operating system in the world — rivaling Apple's iOS — with over 2.5 billion active users spanning over 190 countries. So if you're among the many Android users trying to figure out a way to block a phone number on your smartphone, we've got you covered.

Whether you're a novice Android user or one of those few lucky users who hasn't had to consider blocking/reporting a certain phone number until now, this is one of the most common practices for the majority of smartphone users. 

Simply put, by blocking a phone number, you restrict the person (or AI bot) behind it from contacting you at all. This means that no calls and text messages will go through to your phone from a blocked sender. However, you can still contact a blocked phone number through a phone call and the recipient should be able to answer your call. 

Below, we've prepared a step-by-step guide on how to block a phone number on Android through both the Phone app and your Contacts list. Keep in mind that at the time of writing, we were using a Samsung Galaxy A20e. It's also worth noting that some screenshot elements were blurred/covered for privacy purposes.
