weird data usage

[asphalt cowboy]

I went into settings and under data usage. I noticed that my camera was using the most data. 376mb/all in the foreground. Then the Play Store was next in line fit most usage, 119mb, 30.30mb in foreground and 89.12mb in background. This has me puzzles because I don't ever use these apps except a couple times a month. I use Facebook everyday, all day long and it's data usage is way below the other two. Any ideas on why this is happening or have a fix.

See if you have GeoTagging on in the Camera (not sure if it uses any data or not but couldn't hurt) and check to see if you have the play store set to look for updates on it's own.

Those settings are all off. And yes I back out of all apps when I'm done using them.
