Troubleshooting Galaxy S8 with “Settings has stopped” error

Problem: Hi guys! There was this update recently which downloaded and installed on its own. Not sure what it was about but I think it was installed successfully. Anyways, my phone is a Galaxy S8 and after the said update, an error that says “Unfortunately, Settings has stopped” started to show up. A few seconds before it shows, the phone starts lagging like hell that I couldn’t use it and after the error, there are occasional freezes. I don’t know if it’s just a minor problem or not but I just want my phone to work normally again like before. After all, it’s a very powerful device and I paid so much for this device. Can you help please?

Troubleshooting: The purpose of this troubleshooting guide is for us to know if you can fix this issue on your end or if you need a technician. It’s imperative you try troubleshooting because if the problem can’t be fixed, then you can go back to the store and have the phone replaced especially if the problem can’t be fixed by a technician as well. Don’t worry, you don’t have to do complicated procedures for this. That said, here’s what I suggest you do:

Step 1: Wipe cache partition to replace all system caches

The problem started after an update so there’s a chance that it’s caused by some corrupt or obsolete system caches. Wiping the cache partition will delete all system caches so that by the next reboot, the phone will create new ones that are completely compatible with the firmware. So, follow these steps to boot your phone Recovery mode and then wipe the cache partition:

  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 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 the Power key to select.
  6. Press the Volume down key to highlight “yes” and press the Power key to select.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

Again, the phone will rebuild the caches after this so it will take a little more time rebooting but wait for it to become active, then open My Files to see if the error still shows up and if so, move on to the next step.

Step 2: Reboot your phone in Safe mode

Rebooting in safe mode alone won’t fix the problem, however, it’s necessary for us to determine if the problem is caused by third-party apps or built-in ones. While in this environment, all third-party elements are temporarily disabled so if the problem is fixed while in this mode, then it’s clear enough third-party apps have something to do with it. Here’s how you boot your Galaxy S8 in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen.
  3. When “SAMSUNG” appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see Safe Mode.
  8. Uninstall apps that are causing a problem.

Assuming the problem is fixed in this environment, you need to find the app or group of apps that’s causing the problem. Try to find out if there are available updates for them, then try resetting the apps you suspect are causing the problem and lastly, uninstall them one by one if the issue persists.

Step 3: Backup your files and data and then reset your phone

If the error message still shows up in safe mode, then it is a firmware issue and this last procedure is mandatory to try and fix the problem and it’s also recommended you do this prior to sending your phone in to be checked by a technician.
