I have the latest Lightroom Mobile on my HTC One M9 phone. Although the built-in camera app can take RAW photos, returning DNG files, the option to switch from JPEG to RAW is greyed out in Lightroom Mobile. Does it work on other models of phone?
Unfortunately, unless DNG capture is allowed at the OS level, Lightroom Mobile isn't able to capture in DNG format. Some manufacturers decided not to expose DNG at the OS level, and while we're looking into ways of still providing raw support, there doesn't seem to be much we can do at this point.
OK thanks for the reply. I must say I am a bit surprised that HTC's own built-in camera app can take DNG photos even if they are not supported at the OS level. I have been taking photos with it for a while and the DNGs are imported into Lightroom mobile. It's just a bit slow that way.
