LG E430
Every time I turn on the phone a line of graphics position data appears across the top of the screen.
When I swipe across the screen, coloured lines appear.
If I press the screen, a circle with graphics data appears.
I first thought this must be caused by a particular app I've downloaded, but I've just opened in Safe Mode, and the same problem.
