I have Google + photos auto backup disabled in the Google + settings as well as the photo app settings and my sync settings. Every time I take a picture, it will turn itself back on in my sync settings and I will find the photo has been uploaded. It's still off in all the other places. I prefer to only backup certain photos, not every one I take such as for items I sell on craigslist and ebay so it gets annoying. Has anyone else had this problem?
