title: Suppress My Files app pop up on USB Card mount
body: <p>I'm developing app for Samsung smartphones accessory, that incorporating Mass Storage Device. On device connection I've able to get necessary events and handle it. </p>
  
  <p>But when Mass Storage mounted My Files app is open (I'm testing on Samsung Galaxy S4 GT-I9500). For example files on my device can be encrypted, so My Files app is completely useless in this case.</p>
  
  <p>Is there any way to suppress opening My Files app on card mount? 
  Is app uses some intent, which I can register intent filter, so user can choose which application to open?</p>
