I recently updated my ipad 11 inches and I see a vertical and horizontal line that flickers
I have always had my iPad with me and it was working fine , I live in Dublin when I keep my iPad near the window, it gets extremely cold and I see these lines for one or 2 mins ( this happened only once a year back and was before 2 iOS update) then it disappeared after I start to use it, I recently updated it now the line is permanent why is the update affecting my iPad , how do I fix it?
