The Lightroom app also work with The LG G5 - as this smartphone also does DNG - tried it out this weekend, and not too bad. Also the standard jpeg on the LG G5 are also oversharpened, so not really any good for here, but the DNG could be ok. Haven't tried submitting any of those pics yet. However, you do need to be signed in with your Adobe account to use the Lightoom app, but, you don't need to have a CC account, but then you can't sync your pics. (Better to edit on the computer, than mobile though)
