WIFI Calling Preferences Being Forced to Cellular Preferred
I am experiencing my WIFI Calling Preferences always being forced to "cellular preferred", as are others. I live in an area with poor T-mobile mobile data signal and this recent behavior makes my phone unable to make and receive calls and text messages. I believe the problem only started happening after the next to last T-Mobile software update. Everything was fine for my first 5 months of ownership. A Google search shows posts of other users experiencing the same issue, but no options other than a tedious workaround of manually switching the phone to Airplane mode and changing the WIFI calling preferences back to "WIFI preferred". I have to do this kind of process each time I enter and leave my home, and sometimes have to reboot my phone as well. The times I've forgotten, I've missed package deliveries and went to a doctor appointment when the doctor had left a message that he was out sick. This appears to be a carrier specific issue as far as I can see. I even tried replacing my rock solid Netgear R6400 router with an ASUS AX3000 router with no resulting changes. I'm in a small apartment only 10 feet from the router, with a very strong WIFI signal. I have two Samsung Galaxy S20 phones (March 2020) which both exhibit the exact same behavior. I spoke with T-Mobile Tech support which appeared to be clueless about this issue other than to send me two new S20 phones under warranty to my T-Mobile store. I do not have high confidence in this approach but will try the new phones and report back. Does anyone know anything more? I am not aware of T-Mobile publicly acknowledging this issue.33KViews30likes87ComentariosRe: WIFI Calling Preferences Being Forced to Cellular Preferred
Went to the T-Mobile store on 10/20/20 to get the two "new" phones I was promised. Only one phone was there and it was a refurb despite my specifically being told it wouldn't be. I passed on the refurb. The district T-Mobile manager was there that day. He called T-Mobile from the back room where I couldn't hear and came back with a proposed solution: disable 5G. I put my phones back to LTE, disabling 5G. The WIFI Preferences optimization notifications continued incessantly as before. Actually I noticed that that the phone was actually bouncing between WIFI Preferred and Cellular Preferred settings, as others have described. I had been setting it to WIFI Preferred and observing it being flipped to Cellular Preferred. I did not realize that it would also optimize to WIFI Preferred, although much less often than to Cellular Preferred. Interestingly, a new software update installed to my phone early in the morning on 10/21/20, which was the second update I received during the month of October. For the rest of the day my phone continued changing the WIFI Calling Preferences just as it had before and making frequent notifications. But by the next morning, the behavior abruptly stopped and both of my phones now seem to be working normally for the last six days, despite WIFI Calling being left set to Cellular Preferred and my being in a very weak signal area. Hmmm. So everything seems good now for both phones. Hopefully, I'm not celebrating too soon. I might eventually reenable 5G and see what happens. I'm guessing there may be some kind of learning going on where the phone now might be figuring out where I spend most of my time and connect to WIFI. I wish there were a technical explanation somewhere about what really goes on "under the hood" with WIFI Calling, what the issues have been, and what fixes or other changes have been implemented over time. I will post back if problems reoccur.4Visto4likes0Comentarios
