Mobile device display management

A mobile device comprising:

• a display;
• a microphone;
• a proximity sensor configured to detect an object proximate to the mobile device;
• an accelerometer configured to determine an orientation of the mobile device;
• and
• one or more processors configured to:
• automatically turn off the display of the mobile device in response to the proximity sensor detecting the object is proximate the mobile device and the accelerometer determining the mobile device is in an approximately vertical orientation;
• receive, by the microphone, one or more signals indicating audible input by a user of the mobile device while the display of the mobile device is turned off;
• and
• automatically turn on the display of the mobile device in response to the accelerometer determining the mobile device is in an approximately horizontal orientation,
• wherein the one or more processors are configured to automatically turn on the display only after the display is turned off responsive to the object being proximate the mobile device and the orientation of the mobile device previously comprising the approximately vertical orientation, and
• wherein the orientation of the mobile device is determined as approximately horizontal using the accelerometer when an angle between a vector generally parallel to a major surface of the mobile device and a projection of the vector onto a plane that is generally perpendicular to a direction of gravity is less than or equal to approximately 50 degrees.

A computer readable storage device comprising instructions for causing a programmable processor to:

• automatically turn off the display of a mobile device in response to the proximity sensor detecting the object is proximate the mobile device and the accelerometer determining the mobile device is in an approximately vertical orientation;
• receive, by the microphone, one or more signals indicating audible input by a user of the mobile device while the display of the mobile device is turned off;
• and
• automatically turn on the display of the mobile device in response to the accelerometer determining the mobile device is in an approximately horizontal orientation, wherein automatically turning on the display occurs only after the display was turned off responsive to the object being proximate the mobile device and the orientation of the mobile device previously comprising the approximately vertical orientation, and
• wherein the orientation of the mobile device is determined as approximately horizontal using the accelerometer when an angle between a vector generally parallel to a major surface of the mobile device and a projection of the vector onto a plane that is generally perpendicular to a direction of gravity is less than or equal to approximately 50 degrees.
