One thing I see there is all way a 4 color square in the top right corner. Even when it’s off. I guess it could burn in the LCD 7″ touch screen with time. Any way to fix this?

That sounds like the Pi under voltage warning. I don’t have it on my touchscreen. In which case your Pi needs more power. Common suggestions are try a different PSU or if you think your PSU is ok try different USB leads (some leads cannot carry the amps needed).
