so i accidentally bumped another thread... ignore that. so yeah. this applies to phones as well. if i were to use my ipad/iphone etc. in sunlight, with the sun shining on it, could that ruin the screen? also, if i use my ipad/iphone on a hot day abroad, could that ruin the device? i was in my conservatory, where it was warm, using my ipad, and the sun kept reflecting off the screen, and it got me thinking.
