Clear App Cache/Data:

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

WARNING! By clearing an app’s data, all your personal data stored within the app will be deleted, including high scores, save files, user profiles etc. If you want to avoid losing your app data, clear ONLY the app’s cache.

  1. Open “Settings
  2. Access “Apps
  3. Select the desired app and tap “Storage
  4. Tap “Clear cache
  5. If clearing the cache didn’t solve the issues, try “Clear data” > “OK” (check the Warning above)

Clear the Phone’s Cache Partition:

NOTE: If your phone crashes, freezes or doesn’t work as intended and you are considering a factory reset, you can try clearing the phone’s cache partition instead. This can solve the same issues as a reset, without losing any personal data on the phone storage.

  1. Turn the phone off if necessary
  2. Press and hold “Power” and “Volume down” simultaneously
  3. Release “Power” when the phone vibrates
  4. At the “hTC download menu” release the volume key as well
  5. Press “Volume down” repeatedly to navigate to and highlight “Reboot to bootloader
  6. Press “Power” to confirm
  7. At the “No command” screen, press and hold “Power” and “Volume Up” at the same time
  8. Release the keys once in Recovery
  9. Navigate the Recovery menu using the volume keys and highlight “Wipe cache partition
  10. Press “Power
  11. Once done, ensure “Reboot system now” is highlighted and press “power

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

Reboot to Safe Mode and Uninstall an App:

NOTE: If a third-party app causes issues and prevents you from removing it, you can try uninstalling it form Safe Mode, where all third-party apps are disabled by default.

  1. On the home screen, press and hold “Power
  2. From the “Power options” pop-up, tap and hold “Power off
  3. At the “Reboot to safe mode” prompt, tap “Restart”. After the phone finishes rebooting, you should see a “Safe Mode” watermark in the lower area of the home screen
  4. Next open “Settings” and scroll to “Phone
  5. Tap “Apps” and access “Downloaded
  6. Select the desired app and tap “Uninstall” > “OK
  7. You can now exit Safe Mode by rebooting the device as you would do normally
