So I have had my Hauwei P8 Lite phone since last November, and it has been a flawless experience, up until a couple of days ago, when I notices a yellow mark in the screen in the top right corner. It seems to have come out of nowhere, and I was wondering if it is a software issue, or a hardware issue like water damage? I really don't have the money to get it repaired, so I am hoping it is a software problem.
