For the Samsung Messages app, go to a conversation and select Information > Menu > Block Contact.
Look, we all get annoying text messages (SMS) from time to time. Maybe it’s spam, maybe it’s from someone you don’t want to talk to. Whatever the case may be, you can block text messages on your Android phone.
Of course, as with all things Android, there are various ways to do things. In the case of blocking text messages, it depends on which texting app you use. We’ll cover the two most common apps here: Google’s Messages app and Samsung’s Messages app.
Blocking texts with Google’s Messages app can be done from the conversation by going to the “Details” screen. First, open the app and select a conversation of the number you’d like to block.
Next, tap the three-dot menu icon in the top right and select “Details.”
Now select “Block & Report Spam.”
A pop-up will appear with an option to report the number for spam along with blocking. To only block the number, uncheck the box and tap “OK.”
That’s all there is to it! You will no longer receive text messages or phone calls from the number.
How to Block Text Messages on Samsung Galaxy Phones
To block text messages on a Samsung Galaxy phone, go to the “Information” screen for a conversation in the “Messages” app. First, select a conversation.
Next, tap the drop-down arrow next to the contact name and select the information icon.
Now select the three-dot menu icon in the bottom right and select “Block Contact.”
Confirm your decision by selecting “Block” from the pop-up menu.
Done! You won’t receive text messages or phone calls from the contact anymore.
Unblocking a number is typically the same process as blocking, and some messaging apps have a dedicated section for blocked numbers.
In Google’s Messages app, open the hamburger menu and go to Spam & Blocked > three-dot menu > Blocked Numbers. Tap the “X” next to a number to unblock it.
In the Samsung Message’s app, go to Settings > Block Numbers and Spam > Block Numbers and tap the minus icon next to a number you’d like to unblock.
Simple as that! You will now be able to receive text messages (and calls) from the number.
Blocking calls on Android is largely the same as blocking text messages, but it happens through the phone app instead of the messaging app. When you block someone’s text messages, you are also blocking them from calling you.
With the Phone by Google app, you can go to the “Call History” section and select a contact. Tap the “Block/Report Spam” option.
In Samsung’s default Phone app, go to Settings > Block Numbers and enter a number or choose from the recent calls.
