What worked for me is to select only band 17 LTE. You don't get 4g so you need VoLTE enabled (say goodbye to 911 calls) but I havent had a single data drop in a couple months.
*#2263# from your phone app then go to band selection, LTE, LTE_17
It worked for me, but like others have said it doesn't fix your phone its just a clever workaround
Thanks for your suggestions and notes. I'm getting the run around and blame game from Samsung and Rogers.
Rogers told me to disable LTE for now and test to see if there is an issue when the phone switches from LTE to 4G/3G. I'll try your suggestions. Thanks!
I can't argue with the fact that a repair has worked for you, but it appears that many have gone down that path with limited success. I have been on Rogers-EXT since early January and I have not recieved one duplicate text, nor have I had to reboot my phone even once. The network access on the Rogers-EXT (Bellus roaming) is as close to flawless as you can get. I get LTE+ full speed inside the concrete bunker of a locker room at the Calgary Winsport arena. My friend on an iPhone 7 using Bell can hardly get a signal in the same senario. The phone has great reception when the network is compatible. It's Rogers fault... Samsung is selling this phone all over the world, at least 20+ million. Rogers/ Fido are the only networks with this problem. Samsung might be able to fix it with the right firmware, but they probably don't want to pay for the research to fix it for a network with ~1% of it's device sales... hence why Rogers should either spend the money to figure it out or stop selling this phone.
I have no problem staying with Rogers as long as I keep unrestricted access to Rogers-EXT, otherwise it'll be a waiting game until the end of this contract.
Well, repair looks like it didn't fix a thing. Phone just dropped it's network connection not even 4 days after I picked it up from the Samsung store.
I'm going to take it back tomorrow to the store and demand a new phone, see how that goes. There's no way I'm going to wait another week for a second repair.
