How to fix your Galaxy S9 with Gmail has stopped error

Based on my own personal experience, a Gmail app that keeps crashing is a minor problem. But I’ve encountered cases wherein the error message “Unfortunately, Gmail has stopped” was just one of the symptoms of a serious firmware issue. Gmail is deeply embedded in the firmware so if there’s an issue with the system, it could be one of the apps that may crash. If the firmware got modified or if the owners rooted it and installed a custom ROM, things like this may also happen but assuming that this problem started without apparent reason, here’s what I suggest you do about it.

First solution: Reboot your phone

Before you do anything, make sure you take a little time rebooting your Galaxy S9 especially if this is the first time you encounter the problem because it’s very much possible that it’s just a glitch in the system. Glitches happen all the time regardless of the model or how powerful your phone is. Most of the time, those glitches can actually be fixed by a reboot.

If a normal reboot fails, try doing the Forced Reboot by pressing and holding the Volume Down and Power keys together for 10 seconds or more. It’s more effective than the former but if the problem continues after this, then move on to the next procedure. If this fails, try following these simple steps to force reboot your phone:

  1. Press and hold the Volume Down button and don’t release it yet.
  2. While holding down the volume button, press and hold the Power key as well.
  3. Keep both keys held down together for 15 seconds or until the Galaxy S9 logo shows on the screen.

Once the phone has successfully rebooted, try to open the app to see if the Gmail has stopped error still shows up or not. If it still does, then move onto the next solution.

Second solution: Find out if it’s caused by a third-party app

Third-party applications or those that you manually download from the Play Store and install on your phone may cause performance issues from time to time and this could be one of those cases.

To find out if that’s really the case, you have to start your phone up in safe mode to temporarily disable all third-party apps. Here’s how to restart your phone in safe mode:

  1. Press and hold the Power key until options show.
  2. Tap and hold the Power off option until it changes into Safe Mode.
  3. Tap the Safe mode icon to restart your device.
  4. Once the reboot is successful, you should see ‘Safe mode’ at the lower-left corner of the screen.

If Gmail doesn’t crash in safe mode, it means that there really is a third-party app that’s causing it. Find out which app it is and uninstall it. And here’s how you do that:

  1. Restart your phone normal to boot into standard mode.
  2. Remember the apps you installed about the time when the phone starts to reboot by itself.
  3. Once you already have an app in mind, swipe down from the top of the screen to pull the notification panel down.
  4. Tap the Settings icon on the upper-right corner.
  5. Scroll to and then tap Apps.
  6. Find and tap suspected app.
  7. Tap Storage.
  8. Touch Clear data and tap OK to confirm.
  9. Tap the back key once and then touch Uninstall.
  10. Confirm that you want to remove the app from your phone.

If the Gmail has stopped error still continues after this, then move on to the next procedure.

Third solution: Clear the cache of the Gmail app

The next thing you have to do is to delete the cache of the app. This will replace the old cache with a new one and if it’s just an issue with the app, then this procedure should be able to fix it. Here’s how it’s done:

  1. Swipe down from the top of the screen to pull the notification panel down.
  2. Tap the Settings icon on the upper-right corner.
  3. Scroll to and then tap Apps.
  4. Find and tap Gmail.
  5. Tap Storage.
  6. Touch Clear cache.

After doing this procedure, open the app and see if the Gmail has stopped error still shows up. If it still does, try the next solution.

Fourth solution: Reset Gmail

When it comes to applications, a reset means deleting their data files which usually contain user settings and preferences. Those files will be replaced with a new set and if it’s just a minor problem, this method will fix the problem. Here’s how you do it:

  1. Swipe down from the top of the screen to pull the notification panel down.
  2. Tap the Settings icon on the upper-right corner.
  3. Scroll to and then tap Apps.
  4. Find and tap Gmail.
  5. Tap Storage.
  6. Touch Clear data and then tap OK to confirm.

If the Gmail has stopped still crashes, after this, then it’s time to troubleshoot the firmware.

Fifth solution: Delete all system caches so they’ll be replaced

If Gmail crashes even in safe mode, it’s possible that the cause of the problem is some corrupted or obsolete system caches. This problem may happen after the firmware is updated and while caches are naturally small files, they can also cause trouble if they get corrupted. You don’t have access to individual system cache let alone delete them individually but you can actually wipe off contents of the cache partition to delete them all at once. Once deleted, the firmware will create new files to replace them and if the problem is indeed due to some corrupt files, this procedure can fix the problem.

  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 Galaxy S9 logo shows, release all three keys.
  4. Your Galaxy S9 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step.
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them 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.

After doing this, try to see if the problem still occurs. If it still does, then it’s time for the ultimate solution.

Sixth solution: Reset your Galaxy S9

After wiping the cache partition and the problem is still happening, you have no other choice but to reset your phone. A reset will bring it back to its factory settings and fix the app issue however, make sure you make a backup of your important files and data before the reset as they will be deleted. A reset can fix any app-related problem that’s why I’m confident enough that this issue can fixed by this method provided the firmware of your phone hasn’t been modified in any way.

  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 Galaxy S9 logo shows, release all three keys.
  4. Your Galaxy S9 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step.
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.
