Clear App Cache/Data:

NOTE: If an app crashes, freezes, takes up too much storage or otherwise doesn’t work as intended, you can try fixing these issues by clearing the app’s cache or data.

WARNING! When you clear an app’s data, all the data stored in the app will be deleted, including user profiles, save files, settings, login and payment information 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. Tap “Storage” > “Clear cache” > “OK
  5. If clearing the app data didn’t solve the issues, tap “Clear data” (check the WARNING above)

Clear the Phone’s Cache Partition:

  1. Turn the phone off if necessary
  2. Press and hold “Power” “Volume UP” and the “Home”/”Bixby” buttons at the same time
  3. From the Android screen, release the buttons and wait for Android Recovery
  4. Once in Recovery, press “Volume down” to navigate the menu and highlight “Wipe cache partition
  5. Press “Power” to select the option
  6. Highlight “Yes” and press “Power
  7. Then, highlight “Reboot system now” and press “Power” one last time

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