Help Galaxy S7 data connection deteriorating

[whung]

Phone: Samsung Galaxy S7
Software Version: 6.0.1

Hi there,

I recently did a hardware upgrade and switched from a Galaxy S4 to a S7. Shortly after getting it I noticed that I was having data connection issues. Throughout the day, my phone would go from LTE, then to 4G, then to no data connection, even when I have full bars of reception. The only way I've found to get data back was to restart the phone, then I would be back to LTE again. This would happen couple times a day, and I'm sick of restarting my phone. Rogers Wireless has sent me a replacement phone and I've also switched sim cards, but I still continue to have the same problem. I've also tried wiping the phone (factory reset) and using the phone with no personal files or apps loaded. The only information that was loaded into the phone was my contacts, which was loaded in when I signed into my Google account. This happens randomly, and in various locations. Rogers technical support and advanced technical support haven't been able to resolve the issue yet.

Is there anyone else with the same issue? Any possible solutions would be greatly appreciated.

Thanks

Hi

In
settings
wifi

do you have smart network switch set to off? If your wifi is on it could be dropping data and trying to connect to wifi every time you go through a strong signal. (Long shot, but all I can think of)

I've tried it both on and off, I've also tried it with wifi turned off as well.
