UserresU I found the scrambled pin option on my grapheme but when I choose password instead of pin for the screen lock the keyboard is normal like always. The scrambling just occurs when I choose the pin method.
gk7ncklxlts99w1 I was just thinking the same thing, but it's probably not an option because of the decrease in usability (though, isn't that the point)? In any case I think it should be a thing.
