Change keyboard layout when entering the unlock code
Hey Sailors,
my Jolla was lying on the table and the sun was shining on the display. There I saw very nice fingerprints from my last unlocking. Then i thougt to myself, that if someone is looking at me several times, while I'm performing the unlocking sequence and then take a look on the display, he might guess my unlock code.
Then I remembered, when I was able to make a guided tour in a well secured datacenter. Our guide had to unlock the doors every time we changed an area of the datacenter. The display of the touchsreen looked like an normal display, but he let us take a look on the screen, an every time he was refreshing the display, the numeric keyboard had a different layout like this:
7 8 9 3 5 7 1 9 6
4 5 6 1 2 4 5 0 3
1 2 3 6 9 0 8 4 2
0 8 7
I think, this would be a nice optional security feature.
I'd rather have this as an option in the lock-code section than default, I remember dialpad numbers by gesture not by number.

But usually after you unlock the phone you continue to tap working with apps, that's the difference compare to door lock. Anyway, a agree with @chemist - if only in settings, not by default.

should be part of os.

This makes the whole thing so slow that someone who is shoulder surfing you will find out your PIN.
I pretty much type the lock code (or any PIN for ATM etc.) on "automatic", using muscle memory and to be frank I cannot even remember the numbers easily, they just come out the way I type them. Just like typing on the keyboard, you do not need to look at it, just type.
