I turned off the show passwords setting so that the numbers don't show up on my screen when I'm entering my PIN on the lockscreen. However, the buttons I press still light up as I press them. Is there any way to turn this off? I can't find that setting. Someone could easily see what I'm entering, especially since the numbers are so big. I'm only concerned because I use it on a university campus with many tens of thousands of students....who knows who's watching, haha! TIA~!
