Interesting. I've switched all my phone settings back to the original band (automatic), APN names, etc. and the phone has been working flawlessly for just over a week.
Hopefully this continues and it was just in fact a Rogers bug, but we shall see. I'm in the queue for a loaner phone and repair at the local Samsung shop so if my phone drops out between now and then I'll take it in for repair.
Not sure what everybody else's experience has been this last week.
I have a Samsung Galaxy S7 Edge Blue Coral which I got it on 25Nov2016. Same issue with everyone are having here in this forum, LTE will drop to 4G and to no connection almost every day. Restart the phone or factory reset or network seem to fix the problem but it will come back in a day or two. Phone call and text message are unavailable randomly through out the day.
I have a Share Everything Plan and my other S7 (two phones) lines don't have this issue at all so I though it could be just the S7 edge but I think it is not the case since everyone are having this issue.
Please keep me posted if there is a permanent fix to this issue.
Is it possible for you to switch the sim cards in the two phones? I think we've narrowed this down to a device-related issue, with not all devices having the (hardware?) problem. It sounds like your S7 Edge Blue Coral is faulty but your other regular S7 is not. If you switch sim cards and still experience data drops on the Edge, then it would appear that the device is indeed at fault.
Just FYI, I have a GS7 (NOT Edge) and I experience the data drop issue. I think it is a problem in both S7 and S7 Edge phones and you just have to get lucky when you get one off the shelf (or send it in for repair?).
Don't get me wrong, there is still also a problem with the Rogers network seeing as this doesn't happen on the Belus network. But I think its a combination of a faulty Galaxy S7 and Rogers that gives rise to the data drop issue, because only a small percentage of GS7/Rogers users experience it.
