Clear App Cache/Data:

NOTE: If one of your apps crashes, freezes, or otherwise doesn’t work as intended, you can try fixing the issues by clearing the app’s cache or data.

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

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

Clear the Phone’s Cache Partition:

NOTE: If your phone freezes, crashes, or otherwise doesn’t work as intended and you’re thinking of factory resetting it, alternatively you can try fixing the problems by clearing the phone’s cache partition. This can have results similar to a factory reset without losing personal data from the device.

  1. Turn the phone OFF
  2. Press and hold “Power” ‘Volume down” and the “Bixby” or “Home” buttons simultaneously
  3. Wait for the Android screen and release the buttons
  4. Once in Android Recovery, press “Volume down” to navigate the recovery menu and highlight “Wipe cache partition
  5. Press “Power” to select the highlighted option
  6. Next highlight “Yes” and press “Power” to confirm
  7. Once the process completes, ensure “Reboot system now” is highlighted and press “Power

NOTE: If clearing the phone’s 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 problems 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. Ensure the phone is powered off
  2. Press and hold “Power
  3. At the “Samsung” logo, release “Power” and immediately press and hold “Volume down” instead
  4. Wait for the device to finish rebooting. Once done, release the volume key. You should see a “Safe Mode” watermark in the lower area of the home screen
  5. To remove an app, open “Settings” and access “Apps
  6. Select the desired app
  7. Tap “uninstall” two times to confirm
  8. To exit Safe Mode, reboot the phone normally
