In one embodiment, a phone detects the eyes of a user to determine if the user is looking at the phone prior to the phone initiating one or more predetermined actions. This is useful, for example, to prevent unwanted activation of a control on the phone as when a user inadvertently touches a control on the phone while taking the phone out of a pocket. Another embodiment prevents the phone from taking actions that may change the display, such as dimming, hibernating, sleeping, turning off, etc., if it is determined that the user is looking at the display screen.
