If the application crashes or is terminated by the operating system, it will almost never have the chance to log the issue before terminating. In that case, technical support may ask you to send them the crash logs to diagnose the issue. This articles describes two ways to do that.

Downloading crash logs with iTunes

This is the recommended way, and the easiest. You'll need:

  • a Windows PC or a Mac with a free USB port
  • an iPhone USB cable
  • iTunes installed on the PC or Mac

If any of these is unavailable to you for any reason, you can still send the crash logs by e-mail from the iPhone itself (see below).

Proceed as follows:

  • Connect the iPhone to the PC or Mac with the USB cable
  • Open iTunes
  • Sync your iPhone with iTunes. Regardless of your sync settings, iTunes will download all crash logs from the device

Depending on whether you're using a Windows PC or a Mac, the crash logs will be downloaded to a different folder

Locating crash logs on Windows

On Windows, crash logs are downloaded to hidden folder %APPDATA%\Apple computer\Logs\CrashReporter\MobileDevice. To open it:

  • press Windows Key + R. This opens the Run dialog
  • paste %APPDATA%\Apple computer\Logs\CrashReporter\MobileDevice in the text box
  • press OK

E-mailing crash logs from the iPhone

  • No labels
