A portable communication device having a processor, a battery with a battery sensor, a display screen and a proximity sensor. The processor receives a signal from the display screen indicating whether the display screen is in a disabled state. The processor also receives a signal from the battery sensor indicating the remaining charge of the battery and the processor compares the remaining charge of the battery to a low power threshold. The processor also receives a signal indicating whether the proximity sensor is uncovered. If the display screen is in a disabled state, the remaining charge exceeds the low power threshold and the proximity sensor is uncovered, the device displays content. In certain embodiments, the device transmits a signal identifying the location of the device. In response, the device receives content based on the location of the device and stores the content in memory, filling a queue. |
