Clearing an App's Cache / Data:

NOTE: If one of your applications doesn't work as intended, it crashes, freezes etc. then you could be able to fix these problems by clearing the app's cache or data.

WARNING! If you clear an application's data, you will lose all personal data stored within the app, including login and credit card information, high scores, saved games, profiles etc. Clearing the app's cache however, will not affect personal data, so it's recommended that you try fixing these issues by clearing the cache first. To do so:

  1. Tap "Apps" while viewing a home screen
  2. Tap "Settings" and swipe to "Applications"
  3. Tap "Application manager" and swipe to "Downloaded" or "All'
  4. Select the desired app and tap "Clear cache"
  5. If wiping the cache hasn't solved the issues, tap "Clear data" > "OK"

Wiping the Phone's Cache Partition:

NOTE: In case your smartphone freezes, crashes or doesn't work as intended, then you might want to factory reset your device and see if this fixes all of the issues. However, before factory resetting your device, you could try to fix these problems by clearing the phone's cache partition. Unlike a master reset, wiping the cache can solve a lot of problems without deleting the personal data stored on the internal memory.

  1. Turn off your smartphone
  2. Press and hold the "Power", "Home" and "Volume Up" buttons at the same time
  3. When the phone vibrates, release the "Power" button but continue pressing the other two
  4. When the "Android System Recovery" screen appears, release all buttons
  5. From the recovery menu, use "Volume down" to navigate to and highlight "wipe cache partition"
  6. Press "Power" to select the highlighted option
  7. After the process is complete, "Reboot system now" will be highlighted
  8. Press "Power" to select the option and reboot your device in normal mode

Rebooting in Safe Mode and Uninstalling Apps:

NOTE: If you've installed a third party app that causes issues on your device and prevents you from removing it while running, then you can uninstall it by first rebooting your smartphone in safe mode. In Safe mode, all third party apps are disabled by default.

  1. Turn off your smartphone
  2. Press and hold the "Power" button
  3. At the "Samsung Galaxy" splash screen, release the "Power" key but immediately press and hold "Volume down" instead
  4. Keep pressing the volume key until the smartphone finishes rebooting
  5. Once it reboots, the device should display a "Safe Mode" message in the lower-left corner of the screen
  6. To remove an app, tap "Apps" from the home screen
  7. Go to "Settings"
  8. Swipe to "Applications"
  9. Tap "Application manager" and swipe to the "Downloaded" screen
  10. Select the app you wish to remove
  11. Tap "Uninstall" > "OK"
