Gray line on screen when pinch to zoom on Safari. iPad Air
Hello, when I use Safari on my iPad Air and do the pinch to zoom is often a gray horizontal line in the middle of the screen. I went to the Apple Store in Bologna (Italy) and I have replaced it with a reconditioned. The problem has now resubmitted. Browsing on Safari is really bad and this gray bar appears very often. The problem comes with the Chrome browser. I do not know anymore what to do
