Enterprise Browser 1.5 and HTML5 "file" input

TC70 Scanner using Android

I have a form with a various input types, all of which work within Enterprise Browser 1.5 apart from "file".


Here's the code:


<div class="input-group">
  <label for="inFile">File</label>
  <input class="btn btn-default" type="file" id="inFile" />


The field renders on the page, but clicking the "Choose file" button does nothing.


Using the native Andriod browser the field works as expected, it pops up a menu asking how I'd like to capture the file - Camera, Camcorder, Sound Recorder or Documents.


Any clues?
