Editor’s note: We created these instructions using a Samsung Galaxy S21 running Android 12. Depending on your device’s software version, some steps and menu positions may look slightly different.

Why is Samsung S21 Not Receiving Text Messages From One Person?

Why does my samsung s21 does not receive messages from one person?

If you wonder why this happens, most of the time, you won’t receive messages from one person because the contact is blacklisted on your Galaxy S21. This can happen by accident or maybe you have blocked that person a long time ago but forgot to unblock him/her.

But that does not mean that there are no other reasons for this problem to occur. Here are other reasons why you cannot receive text messages from one person:

  • The contact is blocked from your Samsung Galaxy S21 (already talked about); and
  • A bug in the contact app or the messages app.

Message app has the feature to block texts from saved or unknown numbers on your smartphone. If you have seen the contacts app, it also has the blocking feature, therefore, if one or both apps glitch or have a bug, as a result, you won’t receive messages from one or a few numbers. 

  • Message storage is full

This happens very rarely but if your storage is nearly full so as your messages, you will receive messages but your device will not get them. As a result, you will not be able to see the messages you get.

  • Issues from the carrier’s end

If the contact is blacklisted from your carrier’s end, the messages will not make it to your device.

  • Caching issues

There is a cache behind every app and it is meant to help apps to run faster and smoother without any errors. But sometimes, these cache data can cause various issues on your smartphone; in some instances, cache files of messages, calls, and contacts apps might be the cause.

  • Your S21 does not get messages from an iPhone user.

iPhone has a service called iMessage and the service uses Wi-Fi to send text and messages. Sometimes, this can cause the other person’s messages not to reach your Galaxy S21. 

  • Android system bugs and glitches

Now, we think you have a clear view of the problem. Let’s see how to solve this issue without a sweat.

Fix 01: Check the Blocklist

Before you blindly try any solutions, it is better to check the blocklist on your Galaxy S21 for the person’s number you are trying to receive messages from. This can be easily done if the number is saved on your device and if it isn’t, you might need to ask for that person’s number. 

If you do not know, here is how to check the blacklist on your S21:

  1. Open Message app.
  2. Tap on the three dots at the top right corner and tap on Spam & blocked.
Samsung messages
  1. Check if the person is in the blocked messages.
  2. If so, tap on three dots at the top right corner and tap on “Blocked numbers”.

  1. If the number is on the list, remove it by tapping the “-” button next to it.

Fix 02: Contact Your Carrier

Contact the network provider

Some carriers allow you to block certain services or numbers by reaching them. Even if you do not know whether your carrier supports this feature or not, you can contact its customer care or support and ask whether the number you do not get messages from is actually blocked by the carrier.

If so, you can ask them to unblock it. You might need to confirm your identity and after that, they will remove the number for you. You can then ask the person to send messages and confirm if the number is whitelisted successfully.

Fix 03: Clear Message Box

Another thing you can do to fix this problem is to delete old messages from the message box. There is a similar trick that you can do and that is deleting that person’s (you won’t receive messages from) messages.

Here is how you can delete messages on the Samsung message app. If you use a different message app, the procedure can be a little different.

  1. Open Message app.
  2. Tap and hold to select messages.
  3. Select messages you want to delete.
  4. Tap the trash icon on the top right corner to delete selected messages.

Fix 04: Change the Default Message App

This solution is if you use another app besides the default messaging app on your Galaxy S21.

You should choose the messaging app carefully because some apps can cause various issues. Not every app on the Play Store works well with your Galaxy S21 and only a few apps work perfectly without causing issues.

If the messaging app causes you to not receive messages from one person, you have to change the default messaging app and the problem will be solved.

Here is what you need to follow:

  1. Go to Settings > Apps.
  2. Tap on the “Default apps” (For older android versions, tap the three dots at the top right corner).
Apps - choose default apps
  1. From the list, select the SMS app.
Default apps - sms app
  1. Select the default messaging app (Samsung message).

Fix 05: Deregister the Number From iMessage (if the person is an iPhone user)

Deregister imessage

As we said in the beginning, if the person is an iPhone user, iMessage service can be the reason behind this issue. The solution to this is deregistering your number from iMessage service.

  1. Go to the iMessage deregister page.
  2. Type your number in the number box.
  3. Enter the code on the image.
  4. Tap on the “send code”.
  5. Enter the code received via a message.

Fix 06: Clear the Cache of Messaging App

You can delete the corrupted cache files saved in the Message app to see if the problem can be fixed. Since you removed only the cached data, your messages will not be affected.

Follow these steps to clear the cache of the Samsung message app.

  1. Open Settings > Apps.
  2. Tap on the Samsung Message app.
Allow messages app in notification pop-up style
  1. First, tap on “Force stop”.
  2. Then, tap on Storage.
  3. Finally, tap the “clear cache” button.
Clear message app cache
  1. To make sure the solution is applied correctly. Now, restart the device.
