I was pushing on the screen, and kind of holding it down because it wasn't responding (just due to lag), and it made that kind of colorful swirly thing that would happen if you put your finger on a computer screen or LCD TV. I was confused because i had never seen it do that before! now it's back to normal, no sign of damage, but i was pretty scared for a hot minute!
yeah you pushed too hard. happened before to me, realized i was being a dolt and not just letting my fingers lightly press it.. click takes care of the rest. no need to mash
