daydreaming is supposed to display the clock on screen while charging but it doesn't seem to be doing it. the screen is off when charging. in order to see the clock, i'd have to wake the phone and look at the lock screen.
I tried that myself but it does not work. No matter what I choose in the daydream settings, it wont show it while charging.
It works if I choose 'start now', but it wont show the clock (analog or digital) while charging etc.
I chose 'either'.
