WIFI Calling Preferences Being Forced to Cellular Preferred

You'll get no argument from me that this fiasco should never have been allowed to happen. Assuming that changing this setting finally puts a stop to the problem, it is clear that the tech support people at T-Mobile know nothing about Samsung's efforts to "improve" its products' network performance by overriding user-applied settings. I would have left T-Mobile long ago over this single issue if I could have found a better deal with a different service provider, but I couldn't, so here we are. I have often wondered what other user settings might be getting altered without my knowledge, but I've never caught one in the act. All of that aside, I now believe that Samsung was the "villain" all along, but I blame T-Mobile for not understanding what Samsung has been doing to its customers in a misguided effort to make its products look better.
