To fix that issue you need to reset your hurricane Vegas smartphone. You can do a hard reset or a soft reset to get that problem solved. I'm going to give you hard reset instructions and soft reset instructions. For the soft reset instructions you will need to switch on your phone because soft reset has to be done on the phone settings.
Offer your phone is switched on, go to your settings and scroll down to "backup and reset" and tap in, next you tab reset device, then tap erase everything. Those were the soft reset instructions, remember that by resetting your phone all the data stored on the device memory will be erased and it can't be recovered.
Next I'll give you hard reset instructions, these instructions also work in removing an unknown password, pattern or pin as it does not need the phone to be on. So to hard reset the hurricane Vegas you need to switch it off as you will be resetting the phone from the recovery menu and to enter the recovery menu you have to switch off the hurricane Vegas.
Now hold down the volume down button and power button at the same time until you see the reset menu, tap next of the screen, then on the next menu tap "restore factory". You will see a green robot followed by the hurricane boot screen. Hard reset is done like that. If you need more information please use the ask box on top.
