I've been noticing that the font size of the text is different throughout the device, at different times. Look here at my suretype keyboard.
Notice the "TY UI OP" keys have larger text than the rest of the keyboard. I've also noticed the password sign on screen is different almost every time I pull it up, all though now when I try to take comparison pictures its only coming up in the larger font.
I know this is kind of nit-picking, but I'm curious if anyone's phone is also doing this.
