Samsung Galaxy S9 keeps showing “Settings has stopped” error

Some owners of the Samsung Galaxy S9 have been complaining about the “Unfortunately, Settings has stopped” error that reportedly started after they updated their phones to Android 9 Pie. The error basically means that the Settings app crashes or keeps crashing and most of the time it shows when the user change some settings in the phone or when the app is launched. Unlike the usual app crash issue, this one is a bit more serious since Settings is actually a core application.

This error could mean that there’s a minor issue with the firmware or it could be a sign that some files have been corrupted after the Pie update was installed. In this troubleshooting guide, I will walk you through in doing procedures that could fix this problem. So, if you’re one of the owners of this device and are currently being bugged by a similar issue, continue reading as this article may be able to help you one way or another.

Fixing Galaxy S9 with “Settings has stopped” error

I have personally encountered this error before and I can assure that if this problem started not because of a modified firmware, then you can get rid of it and make your phone work perfectly again without any help from a technician. The most annoying part of this problem is that you won’t be able to change any setting in your phone as the app that handles all configurations crashes the moment you access it. Therefore, here are the things you need to do to fix your device:

First solution: Force restart your Galaxy S9

It is imperative that you begin your troubleshooting by doing the forced restart especially if it’s the first time you encountered the error. It could be just a result of a minor firmware issue or even a glitch. This is actually a simulated battery removal which will refresh your phone’s memory as well as reload all its apps and services. It is very effective against minor firmware-related problems and here’s how you do it:

  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 rebooted, open Settings immediately to see if the “Settings has stopped” error still shows up. If it still does, then let’s isolate the problem.

Second solution: Restart your phone in safe mode

The next thing you have to do is make sure it’s not due to the apps you installed. Restart your phone in safe mode to temporarily disable all third-party applications. If the phone doesn’t show the Settings has stopped error while in that mode, then it means that it’s not really that serious as it’s obviously caused by a third-party app or two. This is how you restart your Galaxy S9 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.

Assuming that the error doesn’t show up in this mode, then it means the culprit is one of the apps you downloaded and installed.

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

You may have to uninstall more than one app to fix this problem.

On the other hand, if you cannot change a setting in your phone even in safe mode due to the error, then it’s time to troubleshoot the firmware itself.

Third solution: Restart in Recovery Mode and delete the system cache

The system creates files to make the performance smoother than when you first turn it on. These files are important for the stability of your device but if there are times when they become corrupted and if that happens, performance issues may occur including app crashes. To rule this possibility out, follow these steps:

  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.

Once the phone has rebooted, launch the app to see if the Settings has stopped error still shows up. If it still does, then it’s time for the ultimate solution.

Fourth solution: Perform the Master Reset

In my experience, I was able to fix similar problem in the past by doing the master reset. Again, as long as you didn’t modify your phone’s firmware, a reset will fix this problem. However, before you do it, make sure to create a copy of your important files and data as they will be deleted during the process. After the backup, remove both your Google and Samsung accounts so that you won’t be locked out of your device after the reset.

Once everything is set and in order, follow these steps to reset your phone:

  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.
