Thin green line from the top to the bottom of my screen
I got my iPad pro less than a month ago and I have just noticed a think green line appear from the top to the bottom of my screen. I have not knocked or dropped my iPad and in fact it has been working fine all day. The iPad is still functioning fine, but the line is very distracting. It also appears in my locked screen.
Not sure why this might be happening?
iPad Pro, iOS 12
