Yes I have been using the LR raw phone camera recently and it is very nice. It has the advantages of dng format as well as keeping the images within the LR workflow environment. I also use the Google camera and Snapseed workflow which has some advantages too. We are spoilt for choice with all these options and the mobile phone cameras are getting better all the time and closing the gap to proper cameras. An Android OS camera would be great thing IMO with the ability for third parties to add functionality to the camera.
BTW, I have just sent you an email regarding a workshop.
