Clear App Cache/Data:

NOTE: If one of your apps freezes, crashes, takes up too much storage 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 app data will be deleted, including user profiles, save files, personalized settings etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Open “Settings
  2. Go to “Apps
  3. Select the desired app
  4. Access “Storage
  5. Tap “Clear cache
  6. If clearing the app’s cache didn’t help, you can tap “Clear data” (check the WARNING above)

Wipe the Phone’s Cache Partition:

NOTE: If your phone crashes, freezes, or doesn’t work as intended and you’re considering a factory reset, alternatively you can try fixing the issues by wiping the phone’s cache partition. This can have results similar to a factory reset without losing personal data stored on the device.

  1. Turn the phone Off
  2. Press and hold “Power” “Home” and “Volume Up” at the same time
  3. At the Android screen, release the keys and wait access to Recovery
  4. Once in Recovery, press “volume down” repeatedly to navigate the menu and highlight “Wipe data/factory reset
  5. Press “Power
  6. Next highlight “Wipe cache partition” and press “Power” again
  7. Highlight “Yes” and press “Power
  8. Once done, ensure “Reboot system now” is highlighted and press “Power” one last time

NOTE: if clearing the cache partition didn’t help, you can check this thread for instructions on how to factory reset the phone instead.

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 where all third-party apps are disabled by default.

  1. If necessary, turn the phone Off
  2. Press and hold “Power
  3. At the “Samsung” logo, release “Power” and quickly press and hold “Volume down” instead
  4. Wait for the device to reboot. Once done, it should show a “Safe Mode” watermark in the lower area of the home screen
  5. To remove an app, first go to “Settings
  6. Access “Apps
  7. Select the desired app and tap “Uninstall
  8. To exit Safe Mode, reboot your phone as you would do normally
