Field Medic is an app that you can use to gather Event Tracing for Windows (ETW) log files for selected information categories. You can also use Field Medic to gather general information about the phone. Field Medic saves the ETW log files and the general information in a folder that is accessible using the USB Media Transfer Protocol (MTP).
Note MTP is enabled on all retail devices by default. It allows for the easy extraction of output files such as Field Medic reports without requiring TShell or other test tools to be enabled. However, you must disable kernel debugging interfaces over USB (KDNET, KDUSB) for MTP to work correctly.
