Yes. on the start screen there should be a "forgot password" option. Sometimes it will only show if you have a few errors, or lock your tablet. You then press it and follow the instructions to unlock it!
Might be your tablet not supported to that app or possibly it should not be a appropriate application :
So download this app from play store
Battery Doctor(Battery Saver)

Contact Apple Support to reset the unit. You will lose all saved data on the device. Otherwise, you can answer security question through Phone Tech Support to reset your code.
If the screen is blurry it may be bad, return it to the store where you bought it, and get another. If you have a camera on each side, it's usually selected in the settings of the camera or webcam software.
