Green box & line jumping around the screen

[Android Central Question]

My phone would be working one min and then next time I check there would either be a green box jumping around or a green horizontal line that sort of looks like it is scanning the screen. I have checked accessibility options and everything is normal. I am only able to navigate around my phone if I click on the green box when it jumps around the screen. I have done hard resets and normal resets. Nothing has worked. Thank for any help/advice.
