title: Permission required when using Intent to call phone?
body: <p>In one of my apps I'm using the following code to issue a phone call:</p>
  
  <pre><code>Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse(...)); 
  startActivity(intent);
  </code></pre>
  
  <p>The docs say I do need the following Manifest permission to do so:</p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.CALL_PHONE" /&gt;
  </code></pre>
  
  <p>Is this really required? I do not understand the difference between a phone and a camera feature. When using a phone intent I do need a permission but I don't need permission for a camera intent:</p>
  
  <pre><code>Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
  ...
  startActivityForResult(intent, 1);
  </code></pre>
  
  <p>Is there a list on hardware features that need a permission if fired with the help of an intent and those that don't?</p>
