Clear App Cache / Data:

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

WARNING! When you clear an application’s data, all personal information stored within the app, including saves, settings, profiles, high scores, login and credit card details will be lost. To avoid losing personal data, clear only the app’s cache.

  2. Launch “Settings
  3. Scroll to “Device” and tap “Applications
  4. Go to “Application manager
  5. Swipe to “Downloaded” or “All
  6. Select the desired app and tap “Clear cache
  7. If clearing the cache didn’t help, you can tap “Clear data” > “OK” (read WARNING above)

Wipe the Cache Partition:

NOTE: If your phone freezes, crashes, or runs out of storage inexplicably and you’re considering factory resetting it, you can try solving these issues by clearing the cache partition. This can yield similar results as a factory reset, without losing any personal data on the internal memory.

  2. Press and hold “Home”, “Volume Up”, and “Power” at the same time
  3. At the “Samsung” logo, release “Power

  6. Press “Power” to select the highlighted option
  7. After the cache partition has been cleared, “Reboot system now” should be highlighted
  8. Press “Power” to confirm

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