title: How to enable USB debugging on Sony Xperia Z1
body: <p>I am unable to find USB debugging on the new Xperia Z1 handset. Various sources suggest that it is under <strong>"Settings > Applications > Developer > USB Debugging".</strong> However, there is no "Applications", "Developer" or anything remotely of use within the settings app.</p>
  
  <pre><code>    Device Info is as follows:
      Model No. C6903
      Android 4.2.2
      Kernel 3.4.0-perf-gde8296d-02197-ga764ca1
      Build No. 14.1.G.1.5331
  </code></pre>
  
  <p>Is there a way to enable it, or am I missing something?</p>
