I've got a 16gb iPhone 6 and i'm constantly getting a 'storage full' message appearing on the screen. When I go to settings>general>usage, it says ive used 12GB and have 0 bytes available (I presume the operating system takes up 4GB of the phones storage). I've got 7 songs, 119 photos, 5 videos and 27 apps. I've got friends with a lot more photos/videos/music/apps than I have on my phone (also 16GB) yet they seem to have GB of storage still available. I'm at the point where I can't even take a photo or even open a Snapchat. It may be something simple, and i'm just being stupid, but I thought i'd see if anyone had any solutions or information on here before I take it back to the store. Thanks a lot.
