How to troubleshooting Galaxy S7 Edge texting issue after Nougat update

Problem: Samsung Galaxy S7 Edge Unlocked. SIM provider is Total Wireless running on Verizon Network. SMS worked fine until Nougat upgrade. SMS actually sends but report as failed. MMS works without issue.

Solution: Most of the time, this issue occurs if files and data had been ruined or got corrupted. As you mentioned on your message that the problem occurs after the upgrade, it’s not far that this might be a simple glitch in the system. The good thing is, it can be fix through simple procedures without bringing your phone to the local shop in your area. These are the methods that you need to do:

Step 1: Delete the Cache and Data of the App

Since, the firmware had been updated there is a chance that the caches and data of your app had been outdated. So, this time, what we have to do now is to reset the app to make sure that all files and data are new and compatible to the firmware.  Don’t you worry, only the app’s cache and data will be deleted in this method.

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Messages.
  5. Tap Storage.
  6. Tap Clear cache.
  7. Tap Clear data and then tap OK.

After you do so, try to send a message and see if the issue still occurs. If so, then proceed to the next step.

Step 2: Boot your phone in Safe mode

In booting your device in safe mode, we have to verify if there’s a downloaded application responsible that your phone has this problem. But if the issue didn’t occur while in this state, then an app caused it and you should find that one and uninstall it to fix the problem. This is how 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.

Step 3: Wipe off contents of the Cache Partition

Since the problem still happening the next thing that you should do is to reset the cache directory of your device. Meaning, we have to delete all temporary files stored in the directory so that the system will be forced to generate newer caches for the new firmware. So, after you perform the method send again a text message (SMS) to know if the issue still persists. If it function normally, thus, the system caches had been corrupted during that time and might caused the issue. Follow these steps:

  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.

Step 4: Reset your phone

Take note,  you can do the reset on your phone if all procedures failed to resolve the issue. Through this, your device will be back to its default settings and all files and data stored on your phone will be wiped out. So, before you proceed transfer all of it to your SD card or personal computer so that you can bring it back to your phone once the issue is fix. Here’s how:

  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.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

I hope that this troubleshooting guide helps.
