title: Turn on screen on device
body: <p>How can I turn the sceen on ?</p>
  
  <p>I tried something like this</p>
  
  <pre><code>adb -d  shell am broadcast -a android.intent.action.SCREEN_ON
  </code></pre>
  
  <p>It really should work, I send broadcast intent it is received by the system, but the screen doesn't turn on </p>
  
  <p>I do not understand what is the problem, is it possible to turn the screen of the device by code  ? I mean with software ? Cause it seems like the turning on of the screen is done just by the hardware button press . . . at least I got that felling , am I wrong ?</p>
