Galaxy S7 (lots of problems, please help!)

[AC Question]

Over the past 4 months, my data usage has gone up and that "Android OS" has been using a lot of background data. What exactly is it using it for and how do I stop it? My data connection often switches from LTE to 4G which then becomes very slow or unusable. This can happen in places where I normally get a great connection too. Restarting my phone or switching data on/off often solves this problem, although it has become very tedious to do. I am really fed up with these issues. I am from Hawaii and few people here suggested me TCAWireless as the best place to solve any Samsung related issues. f anyone has any idea of how to solve these problems please guide me! I am willing to try out anything suggested.

If you go into data usage in your settings you will be able to find out what is using so much data.
