Clear App Data / Cache:

NOTE: In case one of your applications doesn’t work as intended, it crashes, freezes, or takes up too much storage inexplicably, you can try fixing these problems by clearing the app’s cache / data.

WARNING! Clearing an app’s data will result in the deletion of all your personal data stored within the app, including high scores, save files, settings, profiles, credit card and login information. To avoid losing personal data, clear ONLY the application’s cache.

  1. Open the apps drawer
  2. Go to “Settings
  3. Scroll to “Device” and tap “Applications
  4. Tap “Application manager
  5. Swipe to “All” or “Downloaded
  6. Select the desired app and tap “Clear cache
  7. If necessary, tap “Clear data” > “OK” (read WARNING above)

Clear the Phone’s Cache Partition:

NOTE: If your phone crashes, freezes, or runs out of storage inexplicably and you wish to factory reset it, you can try solving these problems by wiping the phone’s cache partition instead. This can yield results similar to a factory reset, without losing any of your personal data located on the phone’s internal memory.

  1. Turn off the phone
  2. Press and hold “Power”, “Volume Up”, and “Home” at the same time
  3. At the “Samsung” logo, release “Power
  4. When the “Android” logo appears, release the other two buttons too
  5. In the Recovery menu, press “Volume down” repeatedly to navigate to and highlight “wipe cache partition
  6. Press “Power” to confirm the selection
  7. After the cache is wiped, “Reboot system now” should be highlighted
  8. Press “Power” one last time to confirm and restart your phone

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

Reboot to Safe Mode and Remove an Application:

NOTE: If you have installed a third party app that causes issues and prevents you from uninstalling it, you can remove the app by first restarting the device in Safe Mode. In this mode, all third party apps are disabled by default.

  1. Turn off the device
  2. Press and hold “Power
  3. At the “Samsung” logo, release “Power” and immediately press and hold “Volume down” instead
  4. Release all keys once the phone reboots. NOTE: A “Safe Mode” watermark should be visible in the lower-left corner of the screen
  5. Go to “Settings” and scroll to “Device
  6. Tap “Applications” > “Application manager
  7. Go to “Downloaded” and select the app you want to remove
  8. Tap “Uninstall” two times to confirm
  9. After the app has been removed, press and hold “Power” and tap “Restart” to reboot your phone and exit Safe Mode
