Clear App Data/Cache:

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

WARNING! When you clear an app’s data, all your data stored within the app, such as user profiles, credit card and login information, save files, high scores etc. will be deleted. To avoid losing personal app data, clear ONLY the app’s cache.

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

Clear the Cache Partition:

NOTE: If your phone freezes, crashes, runs out of storage inexplicably or otherwise doesn’t work as intended and you’re considering factory resetting it, you can alternatively try solving these issues by clearing the phone’s cache partition. This can lead to results similar to a factory reset without losing any personal data from the phone storage.

  1. Turn the phone off
  2. Press and hold “Power” “Home” and “Volume Up” simultaneously
  3. At the Samsung screen, release “Power
  4. At the bugdroid screen, release the other keys too
  5. From the Recovery menu, press “Volume down” repeatedly to navigate to and highlight “Wipe cache partition
  6. Press “Power” to select the option
  7. Then, highlight “Reboot system now” using the volume rocker and press “Power

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

Reboot to Safe Mode and Uninstall an App:

NOTE: If one of your third-party apps causes issues and prevents you from uninstalling it, you should be able to remove the app while in Safe Mode where all third-party apps are disabled by default. To reboot to Safe Mode:

  1. Turn the phone off
  2. Press and hold “Power
  3. At the Samsung screen, release “Power” and immediately press and hold “Volume down” instead
  4. After the phone reboots, you should see a “Safe Mode” watermark in the lower area of the screen
  5. To remove an app, first access “Settings
  6. Go to “Applications” > “Application manager
  7. Access “Downloaded” and select the desired app
  8. Tap “Uninstall” to confirm
  9. Once done, you can exit Safe Mode by rebooting your device normally
