the cloud was uploading pics, doc, and whatnot to the cloud, even though i never turned it on. i went into the applications and disabled it. i hope that took care of it.
I dont think it was enabled on mine. I did disable it though.
I remember on my note 4 that it was trying to constantly upload gigs of music and pics. Drove me crazy because I couldnt figure out what was draining my battery.
I set mine up because I used it to transfer contacts from my old BB Z10. I believe when I first opened it, it wanted to sync everything, but I changed to settings to just do contacts.
