After latest update, GS9 keeps defaulting to Cellular Preferred over Wi-Fi calling

I have very poor (but existent) cellular coverage in my home.  I had no problems with setting Wi-Fi preferred for all of my calls/texting prior to the latest (large) update.  Now, I can select Wi-Fi preferred under Wi-Fi calling, however it never seems to save that setting.  As I am typing this, I have two outgoing messages that aren't sending (spinning circle) because the phone can't decide whether it wants to use Cellular or Wi-Fi.  I want it to use Wi-Fi because I know my Cellular coverage is horrible at my location.  I called into customer service today (somehow without a dropped call) and they made some adjustments on their end, however it fixed nothing. 

Even after selecting Wi-Fi preferred, I will go back to check a few minutes later and the phone has already switched itself back to Cellular preferred.  This is very frustrating.  What can I do to ensure that Wi-Fi preferred will be the default setting?

Thank you

Same issue with a Galaxy S10 Plus after a recent update.  If you are going to give the option to prefer WiFi over cellular then that choice should be respected and not automatically changed or “optimized”.  There is a reason I choose to prefer WiFi over cellular in my home.  As I move around the house the signal strength fluctuates and if I am on cellular service I will drop calls and text messages will not go through. This is an issue that will ultimately lead me to switching carriers as I have no other choice if the T-Mobile phone will not respect my choice to use WiFi preferred.  This one option makes the phone not work when it worked prior to the update that changed this behavior.  It is redundant to give the users this choice if T-Mobile’s network optimization changes it automatically against your wishes.  

 

Unfortunately, I see this has been going on for over a year on other T-Mobile devices (Like the person who started the thread) so my hopes that this is not intended behavior are low which is a shame.  It is unfortunate T-Mobile and Samsung got around to ruining the GS10 Plus in the same way over a year later.  It feels a bit like planned obsolescence If I am being honest.

Same issue with Samsung S8, recent updates have made my phone change randomly from Wi-Fi preferred to Cellular preferred. My signal in my home is also non-existent and it MUST be on Wi-Fi for my phone to work, this is infuriating and I am on the brink of switching to another provider since my phone now completely stops working randomly throughout the day since it is changing to Cellular.

My wife and I just switch to T-Mobile and get the Samsung Galaxy note20 for each of us and both of our phones constantly notify us every minute or two that it switches back and forth on preferred network or Wi-Fi and it's super annoying we have to put our phones the silent in order to get any peace.

It shouldn't need to switch back and forth as in our bedroom where we spend most of our time is where my network setup is located including my Wi-Fi router and I get very poor cell phone service where I live so there should be no question on whether or not it needs to switch or stay on WiFi so I don't know why it's switching.

 

 

Unfortunately, you’re likely going to miss calls and SMS while at home.  The only solution I’ve found to this is to set your phone to Airplane mode when home, and turn on WiFi and Bluetooth manually. Of course, this is a PITA whenever I go out and forget to turn airplane mode off…

Just got another update, and still not patched. T-Mobile, fix this. DISABLE the “automatic adjustment”. Let us set what works for our situation.

I was on the phone with them for an hour today with no resolve.

 

They are friendly as always however it's like they don't know what I'm talking about they try to give me a solution but it's the solution for a completely different problem that I'm not having lol

Yeah I have the same issue, "network optimization" keeps setting my preferred method to cellular when I want it to be wifi due to no cellular signal. This started happening this last update to both my wife's phone and my phone.

 

I know it happened with this last update because I updated my phone first and the update made everything too big on my screen so i had to perform a hard reset. From that day forward I kept getting the notification that "network optimization" has changed my settings back to cellular.

this wasn't happening on my wife's phone. She kept putting off the update until she accidentally pressed update when it popped up as a reminder one day.

literally right when it booted back up and finished updating it popped up with a  "networks optimization." 

Guess what happened.. it too is now reverting back to cellular preferred. Even after saving the change or in the middle of a phone call it will switch back to "cellular preferred."

 

Please fix, this is an annoying glitch.

This just started happening to me too, Samsung Galaxy S20 Plus 

I have the exact same issue.  Poor cellular so I use Wi-Fi calling.  But the phone keeps defaulting to cellular.  No matter how many times I update it.  I need my phone for sales so this is very frustrating.

I'm experiencing the same issue on my new Galaxy A71 5G. My phone keeps "optimizing" my WiFi calling by changing to cellular preferred. I need to keep it set to WiFi preferred, but it won't stay set that way. Very frustrating!

This just started happening to me as well, Note 10+ 5g. All current updates, and every 20 minutes or so T-Mobile “helpfully” tells me that they’ve adjusted my wifi call preferences to prefer cellular. My issues are similar to the original posters… I barely have a cell signal, but enough that the phone keeps trying and I will miss calls or texts because it never tries WiFi until I notice and switch it back manually.

One of the main reasons I’ve been a T-Mobile customer for so long is the Calling over WiFi.

Hey, @drinktigermilk​!

 

Unfortunately, this is the first post that I've seen around the Support Community regarding WiFi calling taking a back seat to cellular after updating to Pie. We're still working to get answers on why this is happening and what we can do to fix it. In the meantime, we're using this thread: Official Android 9.0 Pie Discussion Thread to track user-reported issues related to Pie. When we have more info, we'll be sure to post it over on the linked thread.

This issue is not solved please do not mark it as such I'm using a Galaxy note20 as well as my wife is using the same phone and a lot of people are having this issue right now

seeing as how this issue was for the S9 and was posted a year ago...it was resolved.

Yeah, direct me to where it was resolved you intelligent piece of work?! And explain to me exactly if you're not having this issue and I've seen this issue reported on just about every T-Mobile Samsung phone from the S8 to the Note 20, WHAT ARE YOU DOING HERE?! Man I would love to call you some names that this forum would block but I'll stick to troll. Have a nice day. 😁

Magma I was talking to the piece of work above you that posted (fireguy). This was never resolved and it's NONE of his business anyway. What is he doing in a thread that he's not experiencing the issue? I've had this issue for months now and it's driving me to the point of insanity. I had lived in an area with great signal and then I moved to a new home my wife and I bought that's in a T-Mobile dead zone. It's so bad I sometimes get the non-smoking sign on my signal notifier. So I'm not sure if this actually started sooner than August as I've always had WiFi calling disabled. But now that I need it, it simply doesn't work and notifies me every few mins that its changing the setting I selected, WTH?! Why would thisbevennbe turned on EVER?! If I set wifi calling to cellular priority or wifi why does T-Mobile care? And they make sure you can't disable the WiFi notification. Now I can use package disabler to disable the WiFi calling system app but I need wifi calling sadly enough now due to t-mobiles crappy signal. And when you go to report signal issues to T-Mobile they send you to a petition to get towns to allow towers?! What?! Just redirect a current tower or refit it with another antenna array?! This has me on my last nerve as I'm losing business because of it and T-Mobile doesn't even have the decency to respond?!

Sorry I meant to reply to the other guy not you LOL however you're experiencing the same thing my wife and I are experiencing and I hate the fact that when I manually select Wi-Fi to take priority within 5 minutes it changes I think it should be up to me to choose what I prefer which is the exact same point you're trying to make is ridiculous that something so simple has gone on for so long.

I'm hoping one of their text representative or just anyone that works for them sees these messages and tries to fix it I've been on the phone with him a couple times and they just don't seem to understand what I'm trying to tell them.

Also if the program worked correctly it wouldn't be an issue however I can't understand for the life of me why sitting 15 feet away from my high-end gaming router with five bars of 5G Wi-Fi service it would choose one bar of 3-g over the Wi-Fi connection anyways lol but it does

Check your wifi connectivity as mine always gives me the notification when I lose wifi signal for even a plot second. So I get the message in my house at least 40 times a day on the weekends and like 15 during the week as I'm at work most of that time. As soon as I go to my bathroom which is on the other side from my router it happens. When I go into my garage, same thing, etc. So you need to make sure you're not losing connection. Check your wifi router logs to see if you are. I too have a gaming router, Asus AX11000 which is a $500 router and works great. I don't know why this stupid optimizing wifi is even a thing. If I set it to "A"  it should not try to switch to "B" for ANY reason!

We need a news site to cover our struggle so that's what I’m going to get. Wish me luck!

I live in the foothills in a cell service dead spot, but I’ve got fiber-optics internet and a top-of-the-line WiFi  router, which works great with my Samsung A11. Likewise, at work, the WiFi signal is much stronger than my cell reception when I’m indoors, so I would ALWAYS prefer to prioritize WiFi calling - if I could -  but it keeps changing back to “cellular preferred”…

I’ll add my name to this long list of people who are thoroughly dissatisfied with this automatic reset to “cellular preferred”. This is an incredibly serious flaw in the operating system apparently brought on by a recent update, and whoever it was that thought this “automatic adjustment” was a good design feature oughta be fired. I just recently changed carriers from Verizon to T-Mobile and am already beginning to regret it.  

T-MOBILE OR ANDROID, WHOEVER IS RESPONSIBLE, GET YOUR ACT TOGETHER AND FIX THIS !

they dont post much device issue info wise over here..im mainly on the Sprint site and now that the majority of the new 5G devices are seeing the same updates (TMO/Sprint) you get to see a bit easier how a update affects a device etc..since roughly 2ish months ago a LOT of issues have sprung up on both sides..oddly enough one of said issues only affects the TMO side and not the Sprint side..so add that into the fun of figuring out where the issues are coming in lol.

 

i like to have my info ducks in a row when i post things...anywho..a little reading to get an idea of just how off the wall things have been lately on Samsung world

 

https://community.sprint.com/t5/Device-Solutions/tkb-p/AndroidDevice

 

take a lil gander at how many devices are listed on some of those posts that are being affected lol.. i have been on these sites since the original HTC Evo...issues here and there with maybe one or two devices sure..but this is just nuts lol

T-Mobile you are the provider. Find a fix and get  it released. Thanks.

Hello, TMO are you there?? 

 

Wait you cant hear me cuz my stupid phone keeps unilaterally switching my WiFi call preference to Cellular when I’m right next to my router.

Im having the same annoying issue with my S8.

Fix it! or Im switching carriers. BTW, been with TMO since ‘96.

I also have the same problem with my S20.  Don’t know exactly when it started automatically switching back to cellular, but I think within the last couple of weeks.  Like so many other respondents, I have very poor cell service at my house and need to be on wifi.  Please fix this problem!

Thanks, but this isn't helpful. Those options have been turned off since I got the phone, because I have known of my signal issues. I primarily use wifi.

This has only become an issue since the phone got the most recent update. No settings were changed, and I did review them as your post suggested to make sure. There are no "aggressive" mode options under any of the wifi menus or settings regardless of what is toggled on or off. There is no context menu under mobile data, even when turned on.

This is insane as it's happening on both my and my wife's Note 10+. It started after the August security update. There is no way for me to disable the notifications that I get 50 of on the weekends. Why is T-Mobile not answering or anything?!

no worries.. this original issue popped up a year ago specifically with the S9..the most recent blooper though now covers not only the S9 but pretty much all the way up to the newest released Sammy devices...which came in a couple months ago after a security patch if im remembering right..

Unfortunately I got my phone and so did my wife after this update was implemented but after doing research it is just as you suggested after a security update a few months ago this problem started hopefully they will fix it as it's rather annoying not life-altering unless of course you're my wife and then it's the worst thing ever LOL
