Just allow other Apps as Screensaverapp. There already is a list, but only with the Clock.
Like stated in Stephan's topic,
I know it doesn't solve your issues completely, but someone made this app
it's an all black, no icon, no text app
you can either scroll to it when you go to sleep, or you can set the lametric to schedule mode and set this app as active during a predetermined time.
it's not ideal, but it solves the "to bright" problem :)
hope this helped.
Would be so great if we could choose which app to use as screensaver, as long as the brightness level (which is still too much bright even in night mode...)
+1. Please add a "blank screen" option.
