Clear an Apps Cache/Data:

NOTE: If one of your apps doesnt work as intended or takes up too much storage inexplicably, you can try solving these issues by clearing the apps cache or data.

WARNING! When you clear an apps data, all your personal data stored within the app, including user profiles, will be deleted. To avoid this, clear ONLY the apps cache.

  1. Launch Settings
  2. Go to Apps and select the desired app
  3. Access Storage
  4. Tap Clear cache
  5. If clearing the cache didnt help, tap Clear data (check the Warning above)

Reset the Cache Partition:

NOTE: If your phone crashes, freezes, runs out of storage inexplicably or otherwise doesnt work as intended and youre considering a factory reset, alternatively you can try fixing these problems by clearing the cache partition. This can solve the issues without deleting any personal data stored on the device, as a factory reset would.

  3. Then press and hold Power too
  4. At the Android screen, release all the buttons and wait for the Recovery menu
  5. Press Volume down repeatedly to navigate the menu and highlight Wipe data/factory reset
  6. Press Power to select the highlighted option
  7. Highlight Wipe cache partition and press Power
  8. Highlight Yes to confirm and press Power again
  9. Finally after the process completes, highlight Reboot system now and press Power one last time

NOTE: If clearing the cache partition didnt help, you can check this thread for a guide on how to factory reset the device.
