My galaxy s7 edge has been dropping calls while on wifi calling since the update to nougat. My most recent test shows that the call was able to stay connected for 2 minutes and then dropped and said "wifi connection lost call ended." The wifi connection was not lost. The phone worked flawlessy on the wifi calling prior to the Nougat update. I have no cell signal in my office so I need the wifi calling in order to be able to use my cell phone in my office. I have gone as far as factory resetting the phone and that did not solve the problem. Has anyone successfully used wifi calling on nougat for more than a few minutes? I have the same problem as this post What can I do to fix calls being dropped after last update on Samsung S7 Edge?
