Hi, this is my first post here. A couple of months ago I purchased a Galaxy S7 (model # SM-G930U, Android version 6.0.1) and I'm loving it. However, starting last week I've been getting notifications about software updates being available, and even though I have ample mobile data, it seems to be impossible to download the updates that way, it keeps asking to do it via WiFi. The problem is that the wife is extremely concerned about possible long-term health issues related to wireless signals, and I would like to keep the peace by doing the updates either by mobile data or by Ethernet. (I'd rather not go to some random WiFi network at a store.) So the S7 has an Ethernet option in Settings --> More connection settings, but the option is grayed out. I bought a MiniUSB-to-Ethernet adapter to see if that made it light up, but there was no change. Samsung's manual for the G930U makes it sound like doing Ethernet is the easiest thing in the world: But the problem is that there ARE no prompts, the Ethernet option is grayed out and tapping it has no effect other than making the tapping sound. How to enable Ethernet on the S7? I have to think that the phone wouldn't even show the Ethernet option if there were no drivers for it. (And the manual wouldn't say anything about Ethernet.) I'm also open to ideas on how to command this phone to use my mobile data to download the updates. Thanks very much.
