title: How can I prevent exceptions that aren't caused by user code?
body: <p>I have a Windows Phone 8.1 app in the store that seems to be crashing some.  This would normally be easy to fix, but the exceptions seem to be occurring deep in the Windows API.  When I was originally developing my app, I never experienced any of these exceptions.  I've also searched online, but can't seem to find anything about these.<br/>

  <strong>My question is, how can I solve these exceptions and prevent them in the future?</strong></p>
