Samsung Galaxy S4: How to Block Unwanted or Unknown Text Messages

I believe most of phone's users have been choosing a message as one of their favourite method to communicate with others. That's why no wonder if most of smartphones available today--including with the Samsung Galaxy SIV--have provided the stock Messaging app for their users, so the user will be more easier if they want to send or receive a message in their phone without having to install the app first.

Aside from sending and receiving a message, the stock Messaging app also allows you to block text messages from certain contact matches with the criteria you've specified before, block text messages contain with certain phrase as well as block text messages from unknown senders. This of course will help you to keep your inbox clean from those unwanted or unknown text messages.


How to add or remove a contact in the spam number list?
If you wish to block or unblock text message from certain contact, you can do so by following the step below:
  1. Open Messaging app.
  2. Tap the Menu key then select Settings.
  3. Scroll down to the Spam message settings section.
  4. Tick the box next to Spam settings to enable block text message feature.
  5. Tap Add to spam numbers.
  6. Tap Add button.
  7. Tap Match criteria. Here you'll see four options available, they are:
    • Exactly the same as: this option allows you to enter the full phone number you wish to block.
    • Starts with: this option allows you to enter the beginning of the phone number you wish to block.
    • Ends with: this option allows you to enter the end of the phone number you wish to block.
    • Includes: this option allows you to enter a part of the phone number you wish to block.
  8. Type the phone number in the Enter number field according to the match criteria you've just selected. Or, tap the Contact icon to pick up the desired contact you wish to block from Logs or Contacts app.
  9. Tap Save button.
  10. All phone numbers and criteria you have added will be listed below the Add button.
  11. To unblock blocked phone number or criteria, long tap the desired phone number or criteria and then select Delete. This will remove the selected blocked number or criteria from the spam number list.


How to add or remove a phrases in the spam phrase list?
If you wish to block text messages contain certain phrase, you can do so by following the step below:
  1. Open Messaging app.
  2. Tap the Menu key then select Settings.
  3. Scroll down to the Spam message settings section.
  4. Tick the box next to Spam settings to enable block text message feature.
  5. Tap Add to spam phrases.
  6. Tap Add button.
  7. Enter a phrase you wish to block in the Enter text field. FYI, it's a case sensitive so it'll different if you type "Dear" with "dear".
  8. Tap Save button followed by tapping OK button to confirm.
  9. All blocked phrases will be listed below the Add button.
  10. To unblock blocked phrase, long tap the desired phrase and then select Delete. This will remove the selected phrase from the spam phrase list.

How to block text message from unknown sender?
If you wish to block text message from contacts you haven't added to your Contacts app, you can do so by following the step below:
  1. Open Messaging app.
  2. Tap the Menu key then select Settings.
  3. Scroll down to the Spam message settings section.
  4. Tick the box next to Spam settings to enable block text message feature.
  5. Tick the box next to Block unknown senders.


How to see all blocked messages?
Below are the step to do so:
  1. Open Messaging app.
  2. Tap the Menu key then select Spam messages. All blocked messages will be displayed here.

FYI, you won't receive a notification or message tone when a blocked message is received. They will be redirected to the spam message folder so your inbox will stay clean and you won't lose any received message. But, if you wish to block text messages without log, I believe that there's should be an app available in the Google Play Store which has a feature to do so.

      Try to check whether your son has accidentally enabled call rejection on your phone. You can check it by opening Phone app> tap the Menu key then select "Call settings"> tap "Call rejection"> tap "Auto reject mode" and then select "Off".
      Once done, your phone should be able to receive all incoming calls again.

      When a number has been added in the spam numbers list in the Messaging app settings, all text messages from that number should be blocked and redirected to the Spam messages folder instead of your inbox. However, try to make sure that the number you've added in the spam list is correct.

      Sadly to say that the default Samsung text blocker feature cannot block the messages completely because they will be saved in the Spam messages folder. Alternatively, you can try finding and using a third-party text blocker app that has an option to block messages without logs.

      Can you please tell me what is your model number?
      FYI, I wrote these steps based on my Samsung Galaxy S4 GT-I9500 international version. In some models/carriers, some options may be disabled or not available. For instance, in carrier X, the default feature to block text message is not available because they may have their own block text message services and they want their users to use their services instead of the default feature.

  6. Hi Rehan, thanks for this page. I have an Galaxy S4. I'm a little annoyed with the "Favourites" section in my call area. I have a spam number that keeps calling, so it gets added to my favourites. Is there any way to make sure that only numbers you want to be added to favourites gets added there? On my previous phone, and Iphone, I got to decide who were favourites, and not the phone. this is annoying. I want to decide for myself. Thanks.

      You can add contacts as favourite, but as far as I know the Phone also will automatically add the most frequently contacted contacts as favourite. I can't find or not yet find the option to stop the phone adds contacts as favourite. However, if you don't want certain contact listed in your Favourite list, you can easily remove it by long tapping the contact and then select "Remove from favourites". Or tap the Menu key and then select "Remove from favourites" and then select contacts you wish to remove from the favourites list.
      Hope it helps :)

      If your phone didn't encounter any error then you shouldn't be worried. However, you can enable the "Block unknown senders" option under the spam settings in the Messaging app so that all messages from unknown senders will be redirected to the spam folder automatically.

      Thanks for coming.
      There are three probabilities that can cause your problem:
      1. You might have installed any block outgoing calls app. So, try to take a look at your apps menu and then see whether there's an installed third-party app that has a feature to block outgoing calls. If any, uninstall that app.
      2. You might have enabled and added that contact to the FDN(Fixed Dialling Number) list. FYI, FDN is used to restrict outgoing calls. To check it, do as follows:
      - Open Phone app.
      - Tap the Menu key and then select "Call settings".
      - Tap "Additional settings".
      - Tap "Fixed Dialling Numbers".
      - Tap "FDN list" and then see whether that number is listed here. If so, delete the number to allow you make a call to that number.
      3. Your phone number might have been added to the reject list on your friend's phone. To check this, ask your friend to check in his phone whether he has accidentally added your phone number in his reject call list. If your phone number is in his reject list, ask him to delete your number from the list to make you able to make a call to him.

      If the callers turn on the delivery reports option in their phones, they will get delivery reports to inform them that their messages have been delivered on your phone. But, they won't know that you haven't read it since they don't get any notification to inform them that their messages have been blocked and the read report option is only available for multimedia messages.

      FYI, I'm using S4 International version GT-I9500 and it's now running with Android 4.4 Kitkat. The spam settings option is still available in my stock Messaging app. So, I can't give you any explanation about it in the Verizon version, but there are three options that you can try:
      1. Ask Verizon about it. Who knows that in the latest update they decide to disable this option for certain reason, to make the users use their block text services maybe.
      2. You can use Hangouts app as your default messaging app. This app has a block text feature. You can see the complete steps on how to set Hangouts as the default messaging app here: http://inside-galaxy.blogspot.com/2014/06/samsung-galaxy-s4-how-to-enable-sms.html and how to block text messages in Hangouts app here: http://inside-galaxy.blogspot.com/2014/06/samsung-galaxy-s4-how-to-block-unwanted.html

    1. Hi So Grown,
      Thanks for coming.
      Basically, this feature doesn't completely block the messages because your phone will stay receiving the messages from the blocked numbers, it only redirects the messages to the spam folder. That's why the person you have blocked won't receive any notification or message that will tell them if their messages have been blocked by you.

  15. Hi,
    I have a Galaxy Fame but Google directed me here. I have noticed a text message appeared looking like I have created a new message. I haven't created this message (I wasn't on my phone at the time it suggests this was created) and don't know the number which has been inputted into the recipient bar. I cannot delete the message or change the number. There is no text and no attachment. Is this virus? There doesn't appear to be any other unusual activity on or from my phone. I know there was no-one else on my phone at the time because it was in my bag. Any advice would be appreciated.

      Did you talk about blocking mode?
      If that so, if you want to block all calls except your son then enable blocking mode feature on your phone and then make sure the following things:
      - Under Features section, enable "Block incoming calls"
      - Under Allowed contacts section, choose "Custom" for the "Allowed contacts" option and then add your son's number in the "Allowed contact list".
      You can read more detail about blocking mode here:http://inside-galaxy.blogspot.com/2014/03/samsung-galaxy-s4-how-to-enable-disable_25.html

      If your phone doesn't rings then make sure your son's number is not added into the reject call list. If the number has been added to the reject call list, remove it from the list.

    1. Hi Kelly Cavanaugh,
      Thanks for coming.
      Sadly to say that you can't do so since the allowed contact list is only designed to add contacts that you're allowed to call you when blocking mode is enabled. However, I'm agree that blocking mode will be better if those in allowed contact list cannot only call us but also text us.

      Other way, you can allow all notifications in blocking mode and then enable spam settings in your messaging app so that you can set it to only let a certain person to text you. But, of course, it won't work effectively if you usually get a lot of non-text notifications since you will need to turn off other notifications separately from the related apps.

Samsung Galaxy S5: How to Access Clipboard in Android 4.4.2 Kitkat

Copy and paste text is a feature that can be used in Samsung Galaxy S5. This feature will help you duplicating or moving copied text with ease from one app to another. Since all copied text will be saved to the clipboard, it makes you can not only paste a text that you have just copied, but also paste an older copied text by selecting the required one from the clipboard as long as the clipboard has not been cleared yet.


How to access the clipboard?
Generally, there are two methods that can be used to access the clipboard: 1) in an app or screen where you can enter text by long tapping in a text entry field, 2) in an app or screen where you can see the keyboard by utilizing more options in the keyboard.


Method #1: From a text entry field
If you have ever copied text or taken a screenshot then you can easily access the clipboard from a text entry field in any app or screen. But, as the example, we'll access the clipboard from a text entry field when composing a new text message in Mes…
