I use and android device - I need to open up my dropbox app and go to camera uploads for my phone to start uploading photos. This has been the case for some time, but i'm sure that this happened automatically in the past. I use this feature a lot for work...and many times I go to find my photos in my personal Dropbox on my PC, but they aren't there...then i need to open the app, wait until uploads is complete which can be some time, since I take a lot of construction photos...
