I updated my phone to Android 4.4 (kitkat) yesterday using an unofficial cyanogenmod 11 nightly build.
Google is getting really tricksy with the privacy invasion stuff.
Phone: Press Yes to upload your photos and share them.
Me: No (and I press No).
Phone: Ok. You have chosen to upload your photos later.
Me: Noooooooooo. I did not say later. I said NO!
Phone: Ok, maybe later.
