I've just noticed after the latest ics update a few days ago, sometimes when I put my phone down the screen stays on. I have it set to go off after 1 minute of inactivity. I don't use the smart stay feature. But I've tried it with it turned on and off and it still does it. It seems today a reboot of the phone fixed the problem, for now. BTW it is not plugged into the charger when it does this either. Anyone else have this problem?
