People in Australia often face this issue and need simple solutions that actually work.

Best Way to Block Text Messages on a Samsung Galaxy Phone

Samsung Galaxy phones come with different ways to block messages. These options are found in the settings and messaging apps. You can block a number from your call log or directly in the Samsung Messages app. You can also block contacts saved in your phone. There is a spam protection feature that helps stop scam and unknown messages. 

The phone also has options like auto-reject list, block unknown senders, and report spam. These tools work together using the Samsung One UI and Android 14 system. This makes it easier to control who can send you texts and avoid unwanted messages.

1) How to Block a Number Using Samsung Messages App

Many people get annoying texts from people they do not know or no longer want to hear from. Using the Samsung Messages app is one of the fastest and easiest ways to stop them. It only takes a few taps and works on most Samsung Galaxy models.

  1. Open the Samsung Messages app on your phone.
  2. Find and open the chat with the number you want to block.
  3. Tap the three dots in the top right corner.
  4. Select 'Block number' from the menu.
  5. Choose if you want to block just messages or both calls and messages.

Once done, that number will be added to your blocked list, and you will not get any more messages from them.

2) How to Block Numbers Using Samsung Contacts App

Many Samsung users already have saved contacts they no longer want messages from. Blocking someone through the Contacts app is quick and works well if the number is saved. It also blocks both calls and texts at once.

3) How to Block Text Messages Through Samsung Phone Settings

Sometimes blocking from Contacts or Messages is not enough. If the sender is unknown or spammy, using your phone settings gives you better control.

  3. Tap 'Block numbers' to manage your block list.
  4. Add the number manually or turn on 'Block unknown senders'.
  5. Go back to Settings and tap on 'Caller ID and spam protection'. Turn it on.

These settings stop both messages and calls from numbers you do not want to hear from.

4) How to Block Group Messages and RCS Threads

Stopping group texts is possible within the Samsung Messages App or Google Messages if set as default messaging app. Within a group thread, tap settings to Leave group or Mute notifications. This removes group messaging alerts without deleting the thread. This assists users wanting to stop group texts on Samsung devices.

5) How to Block Spam and Promotional Texts

Samsung phones have easy settings that help stop spam and unwanted texts. These tools are great for blocking messages from unknown or random numbers. They keep your inbox clean and stop alerts from senders you do not want.

  1. Open the message you think is spam.
  2. Tap Report spam at the bottom.
  3. Go to Settings and tap Messages.

  5. Tap on Security and Privacy to control what apps can do with your messages.

These settings are useful if you want to check what is allowed and block what you do not want.

7) How to Block Texts Using Google Messages as Your Main App

Many people use Google Messages as their main app on Samsung phones. It is easy to use and helps block spam, unknown senders, and unwanted group messages. It also gets regular updates to improve spam protection.

8) How to Use Samsung Smart Manager to Help With Message Blocking

Samsung Smart Manager does not block messages directly, but it supports your phone’s overall performance. It helps your phone stay fast by managing background apps, checking battery use, and updating apps. When your phone runs well, blocking tools like spam protection and message filters work better and faster. This makes your message blocking more stable and effective.

How to Unblock a Contact on a Samsung Galaxy Phone

Sometimes, you may block someone by mistake. You can easily unblock them using your phone settings or from the chat screen.

  1. Open Settings on your Samsung phone.
  2. Tap Privacy and safety, then go to Block numbers.

What Is the Difference Between Blocking Calls and Blocking Texts on Samsung

Blocking calls and blocking texts on a Samsung Galaxy are a bit different. If you block someone in Phone Settings, it stops both calls and texts. If you use the Messages app, it only blocks text messages. The Contacts app helps with managing saved numbers, but it does not block anyone unless the number is also in the blocked list. Spam protection helps with both calls and messages by letting you report unknown senders.

Easy Tips to Stop Text Harassment and Block Spam on Samsung

Getting spam texts or rude messages can be stressful. Samsung phones have simple settings to help you stop them. These tips are easy to follow and work on most Samsung phones. The easiest one is to turn on spam protection and caller ID. This helps block spam and unknown numbers. 

You can also use Do Not Disturb during busy hours or at night to avoid unwanted alerts. Besides that keep app permissions limited as this stops apps from sending or reading your messages. Update your phone to the latest version of Samsung One UI and Android. It improves your phone’s safety and helps block messages better.
