When I open any app, there is an odd green, or purple tint. If I screenshot them, they don't show up, but they move. So it's not like I've fractured anything. I thought it was programming but I cannot find the issue. Please help.
Welcome to Android Central! If they're not appearing in screenshots, then the problem is with your screen itself. The screen might be starting to fail, or there might be a loose connection somewhere. Bring it to a repair shop to check.
