I've all but confirmed that it's a Rogers network problem. One of their techs told me on the phone that it's being looked into, but that was all they could see on the ticket.
They will offer replacement phones, but that will not resolve the issue. Repairs will also not resolve the issue, if you have a device with the Exynos modem.
I will be filing a CRTC complaint, and I already emailed all my evidence to CTV to see if they report on it.
But in the meantime, we are stuck with a marginally operational phone unless you can switch carriers.
I had this issue for 6 months from july on. In December my S7's main back button started to not work so I sent it in via my Best Buy geek squad protection plan (13.99/month). they replaced my phone with Im assuming a newer version of the phone and so far for 2 months my phone hasnt lost connectivity once, so I dont have to reset it 5 times a day anymore. So Im pretty sure Samsung changed something in there phone to help with Rogers terrible towers and service. I will be buying another samsung after this issue, but I will not be signing another contract with Rogers as they were useless to deal with on this issue.
Well you can always check your model number, but if you're in Canada, chances are it's the same phone and the same modem in it. Most people's issues are stemming from the ROGERS mobile network. ROGERS-EXT does work a lot better if you can access it, which I am doing now. Hopefully they will have the ROGERS network fixed by the time my ROGERS-EXT network runs out. If they don't, and if they kick me off the EXT network as well I'll be giving them a call that will not be pleasant for them.
But regardless, I think after my contract is up I'm moving to Telus. I don't see them as that much better, but at least I know my phone will work properly on their network.
Add me to the list of S7 owners with the same issues. Picked up a new phone to replace my 2 1/2 year old S5 that never had an issue with service. Tried doing a factory reset, sim card and then a new replacement S7 last week. It almost seems worse with the new phone but I think I am just more upset about the issue now. It took 5 calls to Rogers tech support before I finally talked to someone that admitted that there is a common issue with the S7. I am also finding out just now that this issue has been around for at least a year. I wish I still had my S5 to use but I handed it in for a credit. The worst part of this whole thing is that most of the time when the phone is out of service, it is showing me 4G and full bars. I don't know that I don't have service until I try to make a call or the guy with me gets a call asking to talk to me. I then restart my phone and find there are 4 voicemails and a dozen emails from people that are now aggravated that I was not available to answer questions. There was one day I was connected to a very strong signal of Shaw Wifi and didn't recive emails or phone calls for 4 hours. Someone actually had to come to the job I was at to tell me to call someone.
Use the rogers-ext network if you can. No issues on that one and if Rogers restricts your usage after 3 months tell them to stuff it, threaten to cancel your contract, CRTC complaint, whatever it takes.
