title: how to remove the bluetooth module from android
body: <p>I have a device which runs android 4.1.
  But the device does not have a bluetooth, so I want to remove bluetooth related items from the 4.1 platform (like sharing menu, setting items which contain "bluetooth ").</p>
  
  <p>but it seems a miscellaneous work ( settings, filesharing ,  ).</p>
  
  <p>Is there any method that can  tell the platform that the current devices don't have a bluetooth only by config some files???</p>
