[S20|Exynos] Wifi/WifiCall & 4G on SIM 1 switching - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hey guys,
I have a strange issue with my German S20.
As soon as I connect to my Wifi it starts acting weirdly and kinda always reconnects to my 4G mobile network and then wifi calling just to start all over with the wird connecting issue.
It like this:
1. I connect to wifi
2. Wifi switches to 4G for a blink of a second
3. After a couple of seconds I get wifi calling
4. 4G is reappearing every 4 seconds or so
I have attached a video. Please watch it till the end, its only 1:30 min.

From the video you do not have wifi calling. But perhaps it wasn't captured on the video.
Does this still occur after you successfully obtained wifi calling?

Note II drops WIFI Calling??

Hey I'm a 1st to T-Mobile i'm testing it out before I switch all my lines from Verizon. The question I have is that both the Note II and the GS3 that I have seem to drop the Wifi calling feature randomly. I thought at 1st it may have been some sort of power saving option but it seems to happen in frequently. (Doesnt matter if I'm close to the Router or not)
Is this common? Or am I the only one that has had this happen?
Thanks for any input!

I'm not sure what you mean by turning the App off? When turning the WIFI calling app off does that not mean you are unable to use the feature?? LOL- I have to have this as I have zero reception at my home.
Thanks for letting me know!

This is happening to me as well.
@ scoob go to setting, more setting, deselect the wifi calling app and it should work for you my coverage at my place is between 0 and 1 bar so this should help

mine goes on and off on both my new note 2 and my wife's new galaxy s3. really aggravating. worse on my phone, when in wifi calling, it only answered calls like 1 out of every 10 times, otherwise they went to voicemail. I took the sim out of mine, then put it back in and pushed it in and out and in the holder a few times and now it seems to receive calls in wifi mode but still always in and out and error to connect and such.
My experience with Wifi-Calling has been nothing but troublesome. It's really not reliable at all, sometimes calls comes through sometimes don't.. and when it does come through I can hear the caller but caller cannot hear me. This is quite common problem with wifi-calling and i given up.
If you get even a 1bar of reception near by the window, I suggest calling T-Mobile and getting their Cel-Fi device (Free of charge but has to return when you leave T-Mobile). 1~2 bar by the window will give you full 4bar reception throughout the house on 4G. Only requirement is that you must be living in single house, can't ship out to house that are connected by or close by. I live in townhouse and I just told them I live in single house and got the device in 3 days. =)
Wi-Fi calling is a disaster. For me, incoming audio drops constantly, but the party I am calling can hear me fine. On other occasions, the call will just randomly drop. Came from a Sensation where Wi-Fi calling was perfect. There does not seem to be any resolution... I have spent hours talking to tech support and they have replaced the device with no improvement. I have also had my ISP out and they have verified that my connection is fine. I have even changed the router out... same issues.
With my wifi calling, as soon as I turn kt kn my bars at home would drop where I would hardly get any service. As soon as I turn wifi calling off I magically get bars. So I leave it off and now I get bars pretty much everywhere I go....almost

With wifi calling on, it's suppose to drop signal bars to nothing. You have to go by the wifi bars instead.
Wifi also greatly depends on your network conditions. Cause I have the same problem but it doesnt happen to me that often after some tweaking.
Wifi Issue
I have that problem quite a bit but the signal strength on my router is good. Yesterday i had my internet company reset the cable modem and my wifi problems have decreased a lot but it is still happing. It has to deal with the wifi certificate problems on the Note 2 (Samsung). It is the same problem that I had on the GS3.
Oh well

Uhh, that's the point of wifi calling, to make calls over WiFi and disable your cellular radio. If you turn on Wifi Calling, you should get a blue phone icon on the top left and your "bars" should drop to nothing as your phone turns off the cellular radio. You can still make/recieve calls/sms/mms.
I've been getting an ER01 error lately with invalid certificate, but it seems to be a T-Mobile backend problem? It happens, about 10% of the time and only on my school's network (I have a feeling, it might have to do with the sign in process there).Otherwise, it works well at my apartment.

i get that certificate problem at my house, not too much anymore, but I still see it. and the wifi calling does drop in and out at various times. not a huge deal for me, but the average person wouldn't deal with that.

I've been noticing more & more problems with my service in the last two months. I called T-Mobile to fix it and whatever they did seemed to only help a little. I get times where I get frequent ER01 errors with WiFi & duplicated text messages (same text message gets received by my phone 2-3 times) for an hour or two. I used to also get errors sending texts around that time, but that appears to have gotten better.
Someone else mentioned Uverse, and my WiFi calling problems are at home & work, both of which have AT&T for internet... When I switched from their DSL to Uverse I expected less problems, but got more.

Seems to be a problem that a lot of people are experiencing. Just did a quick Google search and some indication points to a possible T-Mobile back-end problem. I wonder if i call up T-Mobile and ask for wifi calling to be explicitly added to my plan if that'll change anything.

Wifi calls.....

Any calls made over wifi on my note 3 sucks even used third party apps as well but on my note 8.0 wifi calls works good.. I tried few methods to fix it and nothing... Any help??

Suck how? poor voice quality or dropping connection mid sentence and telling you signal is weak, when you stand 2 ft from router?
I had second one: GS3 worked fine, data worked good, but Wifi calling just didn't work on Note3.
After someone's suggestion from here I checked my router, it had auto update off, I changed that to on, verify manually I'm on the latest router firmware and it works like a charm ever after.
If it's the first one, yeah, it could sound better and I hear HD voice does not work yet, so once Tmo fixes that, should be much better, at least between sets supporting it.

Poor voice quality and dropping connection. I stand next to router still the same. So your saying auto update my router firmware and turn auto update on? And your note 3 wifi calls work? Can you give me the steps how to do that and does it interfere with any other devices connected to the router? Thanks...
Router shows firmware is up to date and still I'm having wifi call problems

My note 3 forces my calls over wifi any time it's connected to wifi even when I disable wifi calling or set it to cellular preferred.

WiFi issues?

Not sure if it's just me, but WiFi will randomly disconnect every 5-10 minutes for a few seconds, then reconnect itself. My m8, nexus 5 and nexus 7 2013 are not suffering the same so I'm assuming it's not my router. Anyone have any thoughts?

I think the range is weak in my house my 5ghz on my s5 was 585mbps and my g3 is 296mbps but wifi works great but in my job We have like 5 differend ssids and they all disconnect alot and they all different routers but I guess in my house being closer doesnt log off but at work it does
guys chill! you dont have any problem with your wifi. our phone is looking for a better signal, if it doesnt detected that you have a poor connection it will disconnect itself and it will toggle on your cellular network.
here is your solution
go to your wifi click settings > advance wifi > and uncheck Wi-Fi signal weak and bam. you have your wifi connected all the time!
hit thanks will ya?

Lol same problem s5 wifi signal os stronger on same ssids
I also have this problem and I decided to debug it.
With my jabber client which logs every disconnect I found out that it disconnects from wifi every 5 minutes.
So I opened my router settings and found that only setting that is set to 5 minutes is interval of "Group Key Update". So I changed it to 15 minutes and now it disconnects every 15 minutes.
So it's not solution, but only a workaround. So i will set it to few hours and hope that LG will fix it soon.

WiFi Calling Will Not Enable (H811VK Model, TMO)

Cannot get WiFi calling to turn on. Just says "enabling" but it never turns on. I have a very strong WiFi signal and solid data connection. Anyone else with this issue?
I'm on T-Mobile and I get WiFi calling on both a Galaxy S6 and a Lumia 640
I've gotten that on several phones. Usually a reboot will correct the issue

Factory wipe
Did you do that and not run into issues anymore? I have tried and it keeps hanging up and trying to connect wi-fi calling, and then causing data throughput issues on wi-fi.
Factory wipe cleared all my issues. Use to take me 3-4 min to lock into WiFi. Now like 20 seconds

Wi-Fi Calling. Help.

Hello,
This is the first phone I've had with Wi-Fi calling enbabled.
Each phone call I now make it does it over Wi-Fi. And even though I have 3-4 bars of Wi-Fi while in a call I get an annoying notification beep and it displays I'm going out of Wi-Fi range even though I seen to have plenty.
Haven't rooted the phone yet. Just wondered if someone could she'd some light! Thanks
