Learn how to wipe the ZTE Avid Plus Z828 using the hardware keys. If the phone is not working correctly, you may need to master reset it and also clear the cache partition. These two resets clear different parts of the phone storage. Unlike a master reset, wiping the cache partition does not delete your personal data.

- First, press and hold just the Power key for 1-2 seconds, then quickly press and hold the Volume Up key as well.
