[Q] Cameras with working (non-corrput) RAW/DNG support?

Recently I installed JDX 3.05 (Android M Preview 3 based) and played around with different camera apps the past two days. Every one of them ended up with corrupt RAW/DNG files (according to Photoshop CC 2015). I don't know if this is because of the Android M Preview or recent update to Google Services or some other issue.

Cameras with RAW compatibility that I've tried:
- Manual Camera
- Snap Camera
- Camera FV-5

Anyone have any suggestions or recommendations?
