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.
