text blocker app android

We always want to stay in touch with our friends and family that's why our phone is always at hand. Unfortunately, sometimes unexpected messages from unknown numbers may cause lots of inconveniences and anxiety. This can be a harmless but annoying advertisement or much more dangerous messages from scammers. Children are particularly susceptible to flashy ads and can easily become victims of phishing schemes. Luckily, you can protect them from scammers and frauds by installing a text blocker app for Android.

How to Block Text Messages on Android

How to Block Text Messages on Your Devices without Third-Party Apps

There are many phone models running the Android operating system and each device has its own text messenger installed by default. It makes it almost impossible to describe a method of blocking messages to suit all the gadgets. Therefore, as a basis, I took a stock messaging app preinstalled on Pixel / Nexus Android phones that is called Android Messages. There are two ways to block unwanted messages:

1. How to Block a Number from a Message

If you already have SMS received from a particular contact, you need to open Android Messages and select a thread with this person. Then tap the menu in the right corner (the three dots) and select "People and Options." Choose an option "Block xxx-xxxxxxxx". You will see a pop-up window asking you to confirm that you want to block this number. Tap "Block" if you want no longer receive calls and messages from a selected number.

2. How to Manually Block a Number

This method works if there are no messages from a specific person on your phone. You will have to manually add a number you want to block.

Open the Android Messages app and touch three dots in the right corner. Choose "Blocked contacts" from the drop-down menu. Tap "Add Number" option and enter a number you want to block. After this, just click "Block". That's done. From now on, messages from this number won't bother you anymore.

iPhone owners can fence themselves off SMS-spam by using standard phone settings. Android users will have to resort to third-party software. Here are the best text message blocker apps that will help you permanently be rid of spam and unwanted messages.
