title: Android /storage/emulated/0 and /data/media/0 different permissions
body: <p>I have the LG G3 smartphone.
  During filesystem exploring I spot that </p>
  
  <p>/storage/emulated/0/... directory (recived from system to my local user) have permission that not allowing chmod and chown operations. When I tryed to change some file to 777 I recived 0 result and no error message but nothing happened. Total commander file manager work same way.</p>
  
  <p>But when I try to change filesystem permissin directly by 
  /data/media/0/... I can to do it. </p>
  
  <p>/proc/sef/mounts tell me:</p>

  <p>Cant find than mount options of /storage/emulated/0 refuse permission changing. Or it must be politics?</p>
