title: Programmatically check for Android OTA system updates
body: <p>If you go to Settings->About Phone->Check for updates a check is initiated to see if theres any system updates ready for your phone.</p>
  
  <p>How can I do this action programmatically? Further, I am trying to locate where in the Android source code this happens so I can see it fully and understand it better. Does anyone have any suggestions?</p>
