Windows Universal - Some issues

[SunboX]

First, let me say ... thank you, thank you, thank you! :smile: :heart:

I was waiting for this too long ...

I tried your current Windows Universal sample (master of 2015-12-18) on a Lumia 950.

The app starts, but

• Scanning QR-Code shows a message "Sometimes Being simple is much better. Be simple!"
• Scanning EAN13 codes seems not to work at all
• Pressing the back button does not cancel the scanner overlay, but does close the whole app

I know, this is still in the work. Just wanted to say thanks and give some feedback! :smirk: If you need someone to test these things, let me know (we have some different mobiles here).

So,

1. This was a simple oversight in the sample and is fixed now.
2. It looks like the preview buffer is rotated... I need to change code to account for this. For now you can either rotate your device, or set TryHarder to true in the options.
3. This may be me not knowing how to properly handle back navigation...

[Redth]

So I think #224 should fix #3. Closing this and will track the remaining issue in #241

n.p. ... thanks for your work! :+1:
