When I double clicked the home button my screen changed to what looks almost like a picture negative (muted colouring) I turned it off and on but noo luck. How do I get back to my usual screen colours? Thanks for your help!).
First time using the Apple Support Community. Trying to reset my screen so colors don't look like what can only be described as a picture negative. I recall double clicking the home button when this happened before but as that didn't work this time would be grateful for some help. Many thanks!
