title: How to retrieve number of session from mobile device and non-mobile device from Google Analytics?
body: <p>I want to get number of session from mobile device and non-mobile device in Yes/No format like:</p>
  
  <pre><code>Mobile Device    Count
    Yes             150
    No              670
  </code></pre>
  
  <p>I tried using metric "ga:sessions" and dimension "ga:deviceCategory". But it's showing data for mobile,desktop,tablet etc. </p>
  
  <p>I heard about custom dimensions but I don't know about its use. Can someone please help me on this. I am working on Google Analytics for first time.</p>
