Why do I have these lines?
Samsung Galaxy Tab A 10.1 Model SM-T580 (WIFI)
Out of nowhere I have grey, white lines going across my screen. And I can see impressions behind it of software I was previously using. If my software application had background color, it is still there. If not, the background is white with grey lines thru it. Haven't dropped it, no water on it. Nothing placed on top of it. It's working. Just very distracting. Can anyone explain to a non techie person what I should do? Is having it repaired possible or must it be replaced?
