Clear App Cache / Data:

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

  1. Tap “Apps” on the home screen
  2. Open “Settings
  3. Scroll to “Applications” and tap “Application manager
  4. Access “All” or “Downloaded
  5. Select the desired app and tap “Clear cache
  6. If necessary, tap “Clear data” > “OK” (Read WARNING above)

Wipe the Cache Partition:

NOTE: In case your phone doesn’t work as intended or runs out of storage inexplicably and you are considering factory resetting it, you can try fixing these issues by clearing the phone’s cache partition.

  1. Ensure the phone is turned off
  2. Then, press and hold “Power”, “Home” and “Volume Up” at the same time
  3. At the “Samsung” / “Android” logo, release the buttons and wait for access to the “Android System Recovery” menu

  7. Press “Power” to confirm
  8. After the cache is cleared “Reboot system now” should be highlighted. Press “Power” to confirm and restart your device

NOTE: If clearing the cache partition didn’t solve the issues, you can visit this thread for instructions on how to factory reset the device instead.

Reboot to Safe Mode to Uninstall an App:
