S7 huge data usage after 7.0 update

[Bigdunk78]

I have had this phone for over 1 year, and have always been carefully with data usage. I shut down any sync or other unnecessary things to save data and like to keep things as simple as possible.

After updating to 7.0 the other week I have somehow run up over 2 gig of data on just the OS. Can anyone shed some light on what is causing it?

Thank you for reading.

Go into settings > connections > data usage > mobile data usage. In there you should be able to find out what is using so much data.

You can turn on data saver under Settings-Data Usage.
