And it seems to be getting worse How can I get rid of this random black blotch?! Its inside the screen because nothing happens when I touch it. AHH!!

IF you unhook one of the ribbon connectors going to the panel boards do you get a normal picture on the other half?

no you don't need a manual its easy
Go to your normal home screen on the phone . Ie unlock the screen.
At the top of the screen you will see small white symbols .
put finger on them and pull/ drag finger down to see hidden menu
You will now see wi fi , location, sound, screen rotation, bluetooth
put finger on right hand side of these options and drag finger left

press on mobile hot spot with your finger

Is it possible for you to clean the printheads manually with cotton buds and cleaning solution on this unit. Clean all thoroughly and this might just correct issue.
