Samsung Galaxy S7 Edge can’t send text messages after Nougat update [Troubleshooting Guide]

Text messaging issues are a bit complex than they are since there is always a possibility that the problem is with the network and not your phone. Shortly after the Nougat update for the Samsung Galaxy S7 Edge was rolled out, we started receiving complaints from our readers who reportedly couldn’t send text messages. We feel the need to address this issue once again to look into the possibility that it’s the new firmware that’s causing the problem.

The first one is basically a problem that many of mobile phone owners may encounter every now and then–not being able to send a text message. The second one is about the default texting app that crashes for some unknown reason. We will try to consider every possible cause of these problems and rule each of them out until we can pinpoint what the issue really is.

Troubleshooting Galaxy S7 Edge that can no longer send texts after Nougat update

Problem: Hi guys! I hope you can help me with my problem. I have a Samsung Galaxy S7 Edge and before the update was installed, I can send text messages without any problems. After the update, however, my messages won’t go through anymore but I can still receive messages from my friends. I really don’t have a clue what happened to my phone so if you know how to fix this, please help me. Thanks.

Troubleshooting: We have to verify first if your phone is actually getting a service from your provider before we proceed with our troubleshooting. This is what I need you to do:

Step 1: Dial any phone number

This is to test if your phone can actually make phone calls. If you can’t make phone calls, then it’s probably a service issue and we can only do so much on our end to fix that. The best thing to do is call your service provider as they can easily fix this issue on their end or, at least, give  you an answer why you don’t have service.

On the other hand, if you can make a phone call just fine, then we’ll have to move on to the next step because apparently, you still have a good service.

Step 2: Check the Message Center Number

The Message Center Number is the one responsible in making sure your text messages are sent to their recipients. If your phone has an incorrect center number or if it has been deleted for some reason, then you need to enter the correct one. I am certain you don’t know the correct center number for your phone yet so I’ll show you where to find it and then if there already is a number in the field, you will have to call your service provider to verify if what you have on your phone matches with the number on the system.

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Messages app.
  3. Once the app is opened, find MORE and tap on it.
  4. A small window pops up, tap Settings.
  5. Find and tap More settings.
  6. Now tap Text messages.  
  7. Touch Message center.
  8. You can now see the field where the Message Center Number should be.

Again, call your service provider and ask for the correct center number for your phone. More often than not, this procedure alone can fix texting issues especially if you’re not able to send messages.

Step 3: Check the number you’re trying to send a message to

After verifying your phone has the correct Message Center Number and you still can’t be able to send a text message, try to check if the phone number you’re trying to send a message to is correct. Better yet, try sending a text message to your own number so that you would know if the message goes through and if your phone doesn’t have issues receiving it.

Assuming the message you sent to your own number went through, then the problem isn’t with your phone but on the receiving end. Try texting other people and see if the sending is successful because there’s a chance that the problem occurs only to a specific number.

If the problem persists, you better bring the phone back to the store and let your provider handle the problem for you because as far as basic troubleshooting is concerned, you’ve already done everything to fix the problem to no avail.

I hope this helps.

Galaxy S7 Edge  keeps showing “Unfortunately, Messages has stopped” error

This error basically notifies you about the Messages app that crashed and we are yet to know what caused it. Try to read the problem below to know how this occurs and continue reading for our troubleshooting guide. Remember, we are actually dealing with an actual app-related issue than a texting problem here.

Problem: A message was sent to me and I get the message on the screen “Unfortunately, Messaging has stopped” can not get into my texting the screen keeps popping up even after I tap ok. Tried everything I know but still remains. I have a Galaxy S7 Edge.Thanks!

Solution: Basically, the reason that the error message shows on the screen is because the messaging app crashed. There are two factors we should consider why this issue is happening; either the problem is caused by third-party apps you installed, and the firmware itself may have an issue. Since, we are not sure what triggered the error message there are number of ways that we can do to try to resolve this problem. Here’s what you should do:

Step 1: Clear the Cache and data of your messaging app

Since, the firmware had not been upgraded, it is possible that the caches and data of the app were become outdated and triggered the messaging app to crash. The best thing that we gonna do now is to bring back the app to its default settings. Meaning, you have to delete all settings you’ve made on that particular app including its old caches and data . But don’t you worry, all your messages won’t be erased if you proceed to the procedure. Here’s how to do that:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Messages in the default list or tap Menu icon > Show system apps to display pre-installed apps.
  5. Tap Storage.
  6. Tap Clear cache.
  7. Tap Clear data and then tap OK.

After doing so, try to launch the messaging app and see if the error message still pops up and if it does, proceed to the next step.

Step 2: Boot in Safe mode to verify if rogue apps caused the issue

By booting your phone in safe mode, we can verify if any of the third-party apps is responsible for the problem. If the error message still prompts while in this state, then obviously there’s an app that’s causing all these troubles. In this case, find that app and uninstall it to resolve the problem. Follow these steps to boot in Safe mode:

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Once you’ve successfully booted up in this mode, open Messages to know if the error still shows up. If it doesn’t, it means that the problem is caused by one or some of the third-party apps. You have to find that app, try resetting and updating it but if that won’t work, then you have to uninstall it.

Step 3: Delete the System caches so they’ll be replaced

While in safe mode and the issue was still happening, you can move ahead to the next procedure by deleting the phone’s system caches. Doing this procedure is recommended to all android users especially if the device is misbehaving or has an issue that occurs without apparent reason. If the issue is caused by outdated system files, this procedure will certainly fix it. What it does is wipe off all the contents of the cache partition and in so doing, you’re forcing the phone to recreate those caches during the next boot up process. Here’s how you do it:

  1. Turn off the device.
  2. Press and hold the Volume Up key, Home key, and Power key at the same time.
  3. When the phone powers on, the Android System Recovery screen appears approx. 30 seconds later.
  4. Release all of the keys.
  5. Press the Volume down key to highlight “wipe cache partition.”
  6. Press the Power key to select.
  7. Press the Volume down key to highlight “yes” and press the Power key to select.
  8. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  9. Press the Power key to restart the device.

The phone will take a little longer to boot up but wait for it as it’s actually rebuilding deleted caches. After which, open Messages to know if the error still shows up and if so, then you have no other options but to do the next step.

Step 5: Bring the phone back to its factory default settings

This will bring your device back to its default settings and delete all files and data stored on your phone’s internal storage. So, before you proceed, make sure you transfer all of your important files to your computer or SD card so that you can restore them back again once the issue is fixed. After the backup, make sure you disable the Factory Reset Protection so you won’t be locked out of your device after the reset.
