After drawing the incorrect unlock pattern eight times a timer will appear. You may use your recorded Fingerprint backup once the Timer reaches 0. Note: The option to use a backup Fingerprint is only available if you set that option up when you activated the Pattern screen lock. If you didn't set up a backup and can't remember your pattern lock, the only option is to do an alternate factory reset of the device. Search tutorials for "Reset device" instructions.
Place your finger on the Home key to unlock the screen.
