How to fix Galaxy S10 sending duplicate texts issue | SMS and MMS sent multiple times

Is your Galaxy S10 sending duplicate texts all the time? It’s high time to troubleshoot the issue and find out where it’s coming from.

Galaxy S10 sending duplicate texts fix #1: Restart the app

Duplicate texts may sometimes occur if there’s a bug that causes it within the app. Sometimes, bugs of these type can go away after force quitting the app. Learn how to do that below.

  1. On your screen, tap the Recent Apps soft key (the one with three vertical lines on the left of the Home button).
  2. Once the Recent Apps screen is shown, swipe left or right to look for the Instagram app. It should be here if you managed to run it previously. Then, swipe up on the app to close it. This should force close it. If it’s not there, simply tap the Close All app to also restart all apps.

Another way to force close an app is this:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the messaging app.
  6. Tap Force Stop.

Galaxy S10 sending duplicate texts fix #2: Soft reset

Soft reset, also known as forced reboot, is another way of restarting your device by simulating the effects of a “battery pull.” In older devices with removable battery packs, this is done by simply disconnecting the battery pack. This refreshes the system and potentially remove bugs. Since there’s no easy way to disconnect the battery on your Galaxy S10, you can only simulate the effects. Here’s how:

  1. Press and hold the Power + Volume Down buttons for approximately 12 seconds or until the device power cycles. Note: Allow several seconds for the Maintenance Boot Mode screen to appear.
  2. From the Maintenance Boot Mode screen, select Normal Boot. Note: Utilize the volume buttons to cycle through the available options and the lower left button (below the volume buttons) to select. Allow up to 90 seconds for the reset to complete.
  3. If Maintenance Boot Mode screen won’t show, then your device does not have it. Simply wait for the device to power down completely.

Galaxy S10 sending duplicate texts fix #3: Cache partition wipe

Some messaging  problems are caused by a bad cache partition. This means that the system cache, which is used by Android to load apps quickly, may have become corrupted. To ensure that your phone’s system cache is in top shape, learn how to clear it once every few months. In your situation, you want to do it as a troubleshooting step. Follow these steps to do that:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.
  9. Check for the problem.

Clearing the cache partition won’t result to loss of your personal data so there’s no need to worry.

Galaxy S10 sending duplicate texts fix #4:  Clear messaging app cache

To deal with a messaging app directly, you can clear the messaging cache. Here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the Instagram app.
  6. Tap Storage.
  7. Tap Clear cache button.

Galaxy S10 sending duplicate texts fix #5: Reset messaging app

Should nothing work after clearing the app cache, the next step that you can do is to reset the app to its defaults. This step will delete your texts and MMS so be sure to back them up ahead of time. Once you’re ready, follow these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the Instagram app.
  6. Tap Storage.

Galaxy S10 sending duplicate texts fix #6: Reset network settings

If your S10 is still sending duplicate texts at this time, the next thing to do is to see if clearing the current network settings will help. This usually work on GSM forms but also at times on CDMA devices. Here’s how to do it:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap Reset settings to confirm.

Galaxy S10 sending duplicate texts fix #7: Use another app

If the problem is still not resolved at this point, you can also try to see if it goes away when you use another app. The problem might be within the current app and its code may be recoded to fix it. There are many free messaging apps you can get from the Play Store but we recommend that you try official ones. They tend to be more stable and safer. We suggest that you try Google’s own Android Messages app.

If using another app fixes the problem, try to avoid using the bad app until it gets updated.

Galaxy S10 sending duplicate texts fix #8: Check for bad apps

One other possible reason why your Galaxy S10 is sending duplicate texts can be a bad app. To check, restart the phone to safe mode. On this mode, all third party apps will be suspended so if the problem won’t occur, a bad app must be to blame. To restart your device to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Remember that third-party applications are disabled in this mode so what you can use are pre-installed apps. If the touchscreen issue won’t appear on safe mode, that means that the problem is due to a bad app. Uninstall the app you recently installed and see if that will fix it. If the problem remains, use the process of elimination to identify the rogue app. Here’s how:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S10 is still problematic, repeat steps 1-4.

Galaxy S10 sending duplicate texts fix #9: Wipe the device

At times, texting problems may be brought about by changes to the software. To see if there’s a software bug causing the problem, try to factory reset your phone. Doing so usually clears software bugs. If a software glitch is the reason why your S10 is sending duplicate texts, factory reset might help. To factory reset your phone:
