Clear App Cache/Data:

NOTE: In case one of your applications doesn’t work as intended, takes up too much storage inexplicably etc. you can try fixing these issues by clearing the app’s cache and/or data.

WARNING! By clearing an app’s data, all personal data stored within the application will be deleted. This includes save files, profiles, settings, credit card and login information etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Launch “Settings
  2. If necessary, go to the “General” tab
  3. Tap “Apps
  4. Access “All” and select the desired application
  5. Tap “Clear cache
  6. If clearing the app’s cache didn’t help, you can tap “Clear data” > “Yes” (read WARNING above)

Wipe the Cache Partition:

NOTE: If your phone freezes, crashes, runs out of storage inexplicably etc. and you’re considering factory resetting the device, alternatively you can try fixing these issues by wiping the phone’s cache partition. This can lead to results similar to a factory reset without losing any personal data stored on the phone’s internal memory.

  1. Launch “Settings
  2. Access the “General” tab
  3. Tap “Storage” and wait for the phone to finish calculating the data
  4. Tap “Cached data” > “Yes” to wipe the cache

NOTE: If clearing the cache partition didn’t help, you can visit this thread for a guide on how to instead factory reset the LG K3.
