Clear App Cache and Data:

NOTE: In case one of your applications doesn’t work as intended, crashes, freezes, or takes up too much storage inexplicably, 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 personal data stored within the app will be deleted, including login and credit card information, settings, user profiles, high scores, save files etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Open the apps drawer
  2. Go to “Settings
  3. Tap “Apps” and select the desired application
  4. Tap “Storage
  5. Tap “Clear cache” to clear the app’s cache
  6. If clearing the cache didn’t help, tap “Clear data” (check WARNING above)

Wipe 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 try fixing these issues by clearing the phone’s cache partition instead. This can yield similar results to a factory reset without losing any of your personal data stored on the phone’s internal memory.

  1. First turn the phone OFF
  2. Press and hold “Volume Up” and “Home” at the same time, then press and hold “Power
  3. At the “Android” logo, release all buttons and wait 30-60 seconds for the Android system recovery to appear
  4. In the Recovery menu, press “Volume down” repeatedly to highlight “wipe data / factory reset
  5. Press “Power” to select the highlighted option
  6. Press “Volume down” to highlight “wipe cache partition” and press “Power
  7. Highlight “Yes” using “Volume down” and press “Power
  8. Once the cache is cleared, highlight “Reboot system now” and press “Power

NOTE: If clearing the cache partition didn’t solve the issues, you can try factory resetting the phone instead. Visit this thread for instructions.

Reboot to Safe Mode and Uninstall an App:

NOTE: If you have installed a third party app that causes issues and prevents you from removing it, you should be able to uninstall the app from within Safe Mode. In this mode, all third party apps are disabled by default.

  1. Turn the phone OFF
  2. Press and hold “Power” past the model name screen
  3. At the “Samsung” logo, release “Power” and immediately press and hold “Volume down” instead
  4. Keep Volume Down pressed until the phone finishes rebooting
  5. Once the phone reboots, a “Safe Mode” watermark should be visible in the lower-left corner of the screen
  6. To remove an app, open “Settings
  7. Go to “Apps” and select the desired app
  8. Tap “Uninstall” two times to confirm
  9. To exit Safe Mode, press and hold “Power” and tap “Restart” in the power management pop-up
