On my Nokia 6 Android device Lightroom mobile's camera smears warm colours quite badly on DNG files. The issue is so bad, that fine red detail might disappear completely and for example human body part against gray background might lose color almost entirely as it spreads to surrounding image surface.
I haven't tested with jpg-files yet. The preview, when changing develop settings, shows the photo just fine, as it's rendered from jpg preview, I assume. When the DNG is rendered, color issue reappears.
You can see how it works on desktop here: https://www.youtube.com/watch?v=PaQykCaUb4s&feature=youtu.be
The issue was discussed on forum briefly here: https://forums.adobe.com/thread/2383648
The issue affects both DNG previews in editor and exported photos.
It's been most apparent on red channel, but on the video cyans are affected on the running woman's hair.In general the colors seem a bit washed out, altho this doesn't seem to happen always, though frequently.
Btw here's a link to the file on CC:
