title: How to block user from accessing to Status Bar and Navigation Bar in Lock Screen?
body: <p>I'm developing an security application; which locks screen and apps/data. On the lock screen which will show when user unlocks device, I want to block user from seeing notifications etc. on Status Bar, <em>which I want to make unaccessible, maybe hide completely</em>; also hide/disable Navigation bar on devices that have virtual Home/Back etc. buttons.</p>
  
  <p>How to get this feature on Android devices? Also, is this possible on iOS devices?</p>
  
  <p><strong>TY for taking time...</strong></p>
