Clear App Cache/Data:

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

WARNING! When you clear an app’s data, all your personal data stored in the app, including user profiles, login information, save files, settings etc. will be deleted. To avoid losing personal app data, clear ONLY the cache.

  1. Launch “Settings
  2. Access “General” if necessary and go to “Apps
  3. Select the desired app and tap “Storage
  4. Tap “Clear cache
  5. If clearing the cache didn’t help, tap “Clear data” > “OK” (check the WARNING above)

Clear the Cache Partition:

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

  1. Launch “Settings
  2. Access “Phone Management
  3. Go to “Storage” > “Internal storage
  4. Wait for the phone to finish calculating the data
  5. Tap “Cached data” > “Clear

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.
