I've had my Note for a little over a month now. About a week ago I began noticing that my mobile network data and Wifi were on interfering with each other, it seemed. Like, for instance both of them would be lit up when trying to browse the Internet and it turns out my 4G Lte was on when Wifi was connected. I ended up going over my data limit in a week because of this issue. Does anyone know what's going on? I've already turned Smart Wifi off, and checked "always" for the 'Wifi sleeping' option..... Up until last week I had no problem. I've been having to turn off my mobile network just to make sure the Wifi is what's being used....
