But I think that's a different (much more common?) issue. I also have the feeling that many times when the alarm rings and you're too quick (but not as quick as in my bug report above) the UI needs some time to recognize the tap.

I suspect it's something with the proximity sensor (like with the call-ui), where the screen is too quick to display something, but the touch screen is still waking up (or deciding whether to wake up, who knows).

Maybe when the alarm-ui works OK fmg can jump to the call-ui!
