Clear App Cache/Data:

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

WARNING! When you clear an app’s data, all your personal data stored on the app will be lost, such as user profiles, save files, high scores, credit card and login information etc. To avoid losing personal app data, clear ONLY the app’s cache.

  1. Open “Settings
  2. Scroll to “Phone” and tap “Apps
  3. Select the desired application
  4. Tap “Storage” > “Clear cache
  5. If clearing the cache didn’t help, try “Clear data” > “OK” to confirm (check WARNING above)

Clear the Phone’s Cache Partition:

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

  1. Turn the device OFF
  2. Then press and hold “Power” and “Volume down” simultaneously
  3. Once the phone vibrates, release “Power
  4. At the “hTC download menu” screen, release the volume key too

  6. Press “Power” to confirm
  7. At the “No command” screen, press and hold “Power” and “Volume Up” at the same time
  8. Once in Android Recovery, release both buttons

  10. Press “Power” to select the option
  11. Once the cache is cleared, highlight “Reboot system now” and press “Power” to confirm
