Clear App 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 fixing these problems 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, login information etc. To avoid losing personal app data, clear ONLY the app’s cache.

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

Wipe the Phone’s Cache Partition:

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

  1. Make sure 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
  4. Once in the Android Recovery menu, press “Volume down” repeatedly to navigate to and highlight “wipe data/factory reset”
  5. Press “Power” to select the highlighted option
  6. Next, highlight “Wipe cache partition” using the volume rocker
  7. Press “Power
  8. Highlight “Yes” and press “Power” again
  9. Once done, make sure “Reboot system now” is highlighted then press “Power” to confirm

NOTE: If clearing the cache partition didn’t solve the issues, you can check this thread for a guide 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 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” screen, release “Power” and quickly press and hold ‘Volume down” instead
  4. After the phone finishes rebooting, release the buttons. A “Safe Mode” watermark should be visible 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
  8. Once done, exit Safe Mode by rebooting your phone normally
