Clearing an App's Cache / Data:

NOTE: Clearing an app's cache can fix various issues with the said app, such as freezes / crashes etc. If clearing the cache doesn't help, then you can clear the app's data too.
WARNING! While clearing the app's cache will not affect personal data, clearing the app's data will result in the deletion of all personal information stored within the app, including saved games, login data, settings, credit card information etc. To clear an app's cache and / or data:

  1. Tap the "Apps" icon while viewing the home screen
  2. Tap "Settings"
  3. Under "Phone", tap "Apps"
  4. Go to the "All" tab
  5. Select the desired application
  6. Tap "Clear cache"
  7. If necessary, tap "Clear data" > "OK"

Clearing the Phone's Cache Partition:

NOTE: If your phone is "acting up" and doesn't work as intended (freezes / crashes / you experience an unexplained drop in performance etc.) then you can try and fix these issues by clearing the phone's cache partition. Unlike a master reset, clearing the cache will not delete any personal data stored on the phone's internal memory. To wipe the phone's cache:

  1. Turn off your smartphone
  2. Press and hold the "Volume Down" button
  3. Press and release the "Power" key to turn on your handset
  4. Keep holding "Volume Down" until you see three "Androids" at the bottom of the screen. At that point, release the "Volume" key
  5. From the "HBOOT" menu, press "Volume down" and navigate to "Recovery"
  6. Press "Power" to select the option. A red triangle should pop-up on the screen
  7. Press "Volume Up" and "Power" simultaneously
  8. From the recovery menu, press the "Volume Down" key until you highlight "Wipe cache partition"
  9. Press "Power" to commence the cache wipe
  10. Once the process is done, the "Reboot system now" option will be highlighted
  11. Press "Power" once more to reboot your device in normal mode

NOTE: if clearing the cache hasn't helped fixing the issues, then you might want to apply a master reset. To learn how you can reset the HTC One Mini 2, follow this link for a full guide
