title: Display size is different for the same applications
body: <p>I've made 2 same applications with different package id (AndroidManifest.xml). Package id is the the only difference!</p>
  
  <p>First package id:  com.vlasovsoft.math (exists at Play Store)
  Second package id: com.vlasovsoft.math1 (doesn't exists at Play Store)</p>
  
  <p>The problem is:</p>
  
  <p>the first application (com.vlasovsoft.math) reports me screen size 1440x900</p>
  
  <p>while the second application reports me <strong>true screen size</strong> 1920x1200.</p>
  
  <p>What's the problem ?</p>
  
  <p>My device is Samsung Galaxy Tab A 10.1 2016</p>
  
  <p>Code for displaying screen size:</p>
  
  <pre><code>DisplayMetrics metrics = new DisplayMetrics();
  getWindowManager().getDefaultDisplay().getMetrics(metrics);
  Snackbar.make(view, metrics.widthPixels + "x" + metrics.heightPixels, Snackbar.LENGTH_LONG).setAction("Action", null).show();
  </code></pre>
  
  <p>PS</p>
  
  <p>This problem is not reproduced on my Samsung Galaxy J3 2016</p>
