If you want to see the Android "13" number you tap on the version a few times and then you'll see the clock but if you take your finger and drag the minute clock hand around all the way to 1 o'clock, sometimes 12 o'clock you'll see it pop-up and if you long press and hold onto the screen in random spots it'll change the background like the pictures I added.. Also when you get the minute hand dragged to the 12 or 1 o'clock as soon as it hits it you need to quickly immediately let go otherwise it won't bring the 13 up in the middle of the clock.
Hahaha finally got it.
Gotcha
