title: Android screen brightness Max Value?
body: <pre><code>    WindowManager.LayoutParams layout = getWindow().getAttributes();
      layout.screenBrightness = 1F;
      getWindow().setAttributes(layout);
  </code></pre>
  
  <p>I added this code to button onClick and it worked !
  But is there a higher value since the screen didn't light MAX ??</p>
