Clear App Cache/Data:

NOTE: If one of the apps installed on the phone 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 data stored within the app will be deleted. This includes user profiles, save files, personalized 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 and tap “Storage
  4. Tap “Clear data” > “OK
  5. If clearing the app data didn’t solve the issues, tap “Clear cache

Clear 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’re considering a factory reset, alternatively you can try fixing these issues 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 Up” and the “Home”/”Bixby” buttons at the same time
  3. At the Android screen, release the keys and wait for access to Recovery
  4. Press “Volume down” repeatedly to navigate the 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 reset is done, “Reboot system now” should be highlighted. Press “Power” one last time

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