Clear App Cache / Data:

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

WARNING! Clearing an app’s data will delete all your personal information stored within the app, including login and credit card information, high scores, save files, profiles etc. To avoid losing data, clear only the app’s cache.

  2. Open “Settings
  3. Scroll to “Phone” and tap “Apps
  4. Select the desired app and tap “Storage
  5. Tap “Clear cache
  6. If necessary, tap “Clear data” > “OK” (read WARNING above)

Wipe the Cache Partition:

NOTE: If your phone crashes, freezes, runs out of storage inexplicably etc. and you’re considering factory resetting it, you can try fixing these issues by clearing the cache partition instead. Unlike a factory reset, clearing the cache partition will not delete personal data stored on the device’s internal memory.
