How can I turn the sceen on ? I tried something like this <pre class="prettyprint"><code>adb -d shell am broadcast -a android.intent.action.SCREEN_ON </code></pre> It really should work, I send broadcast intent it is received by the system, but the screen doesn't turn on 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 ?

<pre class="prettyprint"><code>adb shell input keyevent KEYCODE_POWER </code></pre> Works to turn on screen (when display is off) Works to turn off screen (when display is on/awake)
