I have been running into a pretty annoying bug since I got my XS. After you swipe to unlock and immediately start typing on an empty area on the bottom of the screen (where a keyboard would normally appear), ghost keys appear on screen and you are not able to swipe to the next screen (for as long as the bug is present, which is a second or two). Note: The bug is only present when you have set an alphanumeric code for your iPhone. When a 4 or 6 digit numeric code is set, there is no problem. The bug is still present in the 12.2 beta's. I reported the bug multiple times now to Apple, but maybe I'm alone with this problem? Anyone else?
