Wi-Fi randomly turns on, even when T-Mobile signal is available...

    My mom's S7 switches over to Wi-Fi calling when signal isn't available at her job. But, when she comes home (where T-mobile signal is pretty good), the Wi-Fi calling randomly turns on even though I have "Cellular Network Preferred" selected. This issue doesn't happen on my HTC 10 and my dad's S7.


    It seems like her phone "forgets" the "Cellular network preferred" setting. When the wifi calling randomly turns on, I check the wifi calling setting. Usually, it says something like, current setting selected is "Cellular network preferred". But when this issue happens, that text is missing. But the "Cellular network preferred" is still selected.

     

    I have tried resetting the phone, it didn't help.
