US Patent 9634911 Communication device event captures

A user interaction or a timer event is detected in a communication device. A timestamp is associated with the user interaction or the timer event. In response to detecting the user interaction or the timer event in the communication device, the user interaction or the timer event and the timestamp are stored in a packet log file associated with the communication device. The packet log file can also include a packet trace of packets that are sent to and received by the communication device. This allows the user interactions and/or the timer events to be displayed chronologically in relation to the packets sent to and received by the communication device.
