I'd like to hear about solutions/ideas for this also...
I just got a note 5 and was having issues getting LR mobile to recognize the dng files created by the camera in pro mode . What I found was if I moved the dng files into a folder by themselves LR recognized them not sure if that helps or not but thought I would throw it out there
Granted a PC is a better place to edit RAW, but there can be times I want to fix an exposure or other RAW edit with only my Note 5 in tow.
I downloaded Adobe Lightroom Mobile however I cannot figure out the work flow to get the DNG files into Lightroom Mobile. The only way I can seem to figure it out is auto add but it just doesn't work on my device. There is no way to manually select the DCIM\Camera folder. I can't manually add the DNG file into the app.
You might find the following discussion (from April '14) interesting: http://blogs.adobe.com/lightroomjournal/2014/04/the-field-triage-opportunity-for-lr-mobile .html
