Clear an App’s Cache/Data:

NOTE: If one of your apps doesn’t work as intended or takes up too much storage inexplicably, you can try solving these issues by clearing the app’s cache or data.

WARNING! When you clear an app’s data, all your personal data stored within the app, including user profiles, will be deleted. To avoid this, clear ONLY the app’s cache.

  1. Launch “Settings
  2. Go to “Apps” and select the desired app
  3. Access “Storage
  4. Tap “Clear cache
  5. If clearing the cache didn’t help, tap “Clear data” (check the Warning above)

Reset the Cache Partition:

NOTE: If your phone crashes, freezes, runs out of storage inexplicably or otherwise doesn’t work as intended and you’re considering a factory reset, alternatively you can try fixing these problems by clearing the cache partition. This can solve the issues without deleting any personal data stored on the device, as a factory reset would.

  1. Turn the phone OFF
  2. Then press and hold “Home” and “Volume Up” at the same time
  3. Then press and hold “Power” too
  4. At the Android screen, release all the buttons and wait for the Recovery menu
  5. Press “Volume down” repeatedly to navigate the menu and highlight “Wipe data/factory reset
  6. Press “Power” to select the highlighted option
  7. Highlight “Wipe cache partition” and press “Power
  8. Highlight “Yes” to confirm and press “Power” again
  9. Finally after the process completes, highlight “Reboot system now” and press “Power” one last time

NOTE: If clearing the cache partition didn’t help, you can check this thread for a guide on how to factory reset the device.

Reboot to Safe Mode and Remove an App:

NOTE: if one of your third-party apps causes issues and you are unable to remove it, you should be able to uninstall an app from Safe Mode. In this mode, all third-party apps are disabled by default.

  1. Turn the phone OFF if necessary
  2. Next, press and hold “Power
  3. At the Samsung screen, release “Power” and quickly press and hold “Volume down” instead
  4. Once the phone finishes rebooting, release all the buttons. A Safe Mode watermark should be shown in the lower area of the screen
  5. To remove an app, first access “Settings” > “Apps
  6. Select the desired app and tap “Uninstall
  7. To exit Safe Mode, reboot your phone as you would do normally
