Abstract:
1. A computer program stored in a non-transient computer medium executable by a cell phone having a display screen, user input keys, and a light sensor, the cell phone providing a standard incoming display screen for an incoming call and a standard outgoing display screen for an outgoing call to: (a) detect phone activity on the cell phone indicating a beginning of an incoming call or outgoing call; (b) for both detected incoming and outgoing calls, check ambient brightness in the environment of the cell phone using the light sensor; (c) for both detected incoming and outgoing calls, only when the ambient brightness is below a predetermined threshold, indicating possible accidental dialing, prompt the user with a supplemental display different from the standard incoming and outgoing screen on the display screen to process the call or hang up, the supplemental display being independent from the standard incoming display screen and standard outgoing display screen and accepting user inputs for hanging up or accepting a call; (d) after step (c) when a first supplemental key press on the input keys indicating an intent to terminate the phone activity is received within a predetermined time window in response to the supplemental display, terminate the phone activity; (e) after step (c) when a second supplemental key press on the input keys indicating an intent to process the phone activity is received within the predetermined time window, allow the phone activity to complete; and (f) when neither the first nor second supplemental key press is received within the predetermined time window, terminate the phone activity.
