Clear an App’s Cache/Data:

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

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

  1. Launch “Settings
  2. Go to “Apps
  3. Select the desired app and go to “Storage” > “Clear cache
  4. If clearing the app cache didn’t help, tap “Clear data” (check WARNING above)

Wipe the Phone’s Cache Partition:

NOTE: If your phone crashes, freezes, runs out of storage inexplicably or otherwise doesn’t work as intended and you’re considering a factory reset, alternatively you can try resetting the phone’s cache partition instead. This can have similar results to a factory reset without the loss of personal data stored on the device.

  1. Ensure the phone is powered Off
  2. Press and hold “Volume Up” and “Home” at the same time, then press and release “Power
  3. At the Android screen, release the buttons and wait for access to Android Recovery
  4. Once in Recovery, press “volume down” repeatedly to navigate to and highlight “Wipe data/factory reset
  5. Press “Power” to select the option
  6. Highlight “Wipe cache partition” and press “power
  7. Highlight “Yes” and press “Power” to confirm
  8. Once done, highlight “Reboot system now” and press “Power” one last time

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

Reboot to Safe Mode and Remove an App:

NOTE: If one of your third-party apps causes issues and prevents you from removing it, you should be able to uninstall the app while in Safe Mode. In this mode, all third-party apps are disabled by default.

  1. Turn the phone Off if necessary
  2. Then, press and hold “Power
  3. At the Samsung screen, release “Power” and quickly press and hold “Volume down” instead
  4. Once the phone finishes rebooting, release the buttons. A “Safe Mode” watermark should be visible in the lower area of the home screen
  5. To uninstall an app, first open “Settings
  6. Go to “Apps” and select the desired app
  7. Tap “Uninstall
  8. To exit Safe Mode, reboot your device as you would do normally
