So, i just noticed that my phone used 5.1GB wifi data over night without me doing anything. Normally that is not the biggest problem, but over weekends when i am at my girlfriend's it is. They only have 20gb day + 20gb night data.

The two main culprits: OS Services with 2.82GB, and Samsung Cloud with 2.35GB data. How do I deactivate Samsung cloud firstly? I never activated it to begin with. And how does OS Services use that much anyways? How can I limit those to things? I never had this issue with my Xperia Z2 before.

First image is the first usage report from "My Data Manager". Tge second image clearly shows Samsung cloud with 430Mb data only.
