title: App auto rotates even with device orientation locked
body: <p>I am working on normal activity based application.
  I have turned off device orientation from device settings.
  When I run my app on device, the app changes orientation based on device movement.
  I have no clue how can an app rotate even when device orientation is locked.
  There is no such instance/issue reported or ever asked on stack overflow or any other forum.
  Please point out, what I might be missing?</p>
