filefield does not work for Samsung S5

Hi,

I've successfully used filefield with xhr2 to upload files for browser based apps and native app on Samsung S3. However it doesn't work on Samsung S5 - when you click the "Choose File" button it doesn't bring up a dialog box to select a image from your phone gallery or camera.

Is this an expected issue with filefield/xhr2 on Samsung S5?

FYI, I'm using SenchaCmd 4.0.4.84 and sencha touch 2.4.0.

Thx.
