[Q] Toggle mobile data radios?
When I am at home on wifi, and even with "mobile data" turned off, I still have a 4G LTE icon in my status bar. Does this mean the cellular data radios are still on and drawing power? If so, how can I truly turn off the cellular data radios (but keep the cell radio for voice on)?
Note: I did see the *#*#4636#*#* trick, but I'm hoping for something much simpler, ideally a toggle widget. My phone is rooted but I do not want a custom ROM.
(Apologies if this question has already been answered, but I wasn't able to find it through searching.)
