After updating Galaxy S9 to android 9 WiFi calling no longer works

Hi,

I have a Galaxy S9 purchased directly from BT. This morning it updated to Android 9 and now WiFi calling no longer works

All calls and texts are going over a regular cellular network. The WiFi calling icon is not displaying in notifications - it's just showing VoLTE.

Additionally when making a call, the call button no longer shows it as a WiFi call.

All the settings on my phone related to WiFi calling are switched on and WiFi calling worked prior to updating to Android 9.

I have tried turning off and on the WiFi calling settings - it doesn't work. I have restarted my phone, that doesn't work either.

My preferred option is to have WiFi calling work again. If that is not possible, how do I go back to the pre-update software version so I can get WiFi calling back again?

Is it possible for BT to describe and reactive WiFi calling on my account, would that force my phone to redownload the correct carrier settings or something?

Any help appreciated

I had the same problem with my Galaxy Note 9 and all i did was do a factory reset and hopefully it'll come come like it has on my phone.

 

Hope this helps

Still having problems with this. I am now getting quite agrivated that BT sold me this device by advertising it had WiFi calling and saying nothing about WiFi calling being broken by future software updates.

Nothing I have done, including resetting has worked, which means I am without the feature I purchased this device for.

Very frustrating

I have a similar problem with my OnePlus 5T since upgrading it to Pie.  For me, WiFi calling will only work very occasionally - mostly it defaults back to VoLTE.  A work around I've found is to enable airplane mode, then manually turn on WiFi and BlueTooth - i.e. completely disable the mobile stack.  I think my problem is specific to OnePlus TBH (and their support is worse than useless), but might be worth a try.

Wifi calling will kick in if you don't have a 4g signal so if you do have a signal it will be volte. But if you want wifi calling turn your 4g off in network mode.

Re: After updating Galaxy S9 to android 9 WiFi calling no longer works

On my 5T, I can set a preference - Wifi Calling or VoLTE. I have Wifi as preferred, so it uses Wifi, then 4G, then mobile. However, as I said, it doesn't work reliably on Pie - and I have to turn the mobile stack completely off using Airplane mode - then it work. Turning off data but leaving mobile enabled doesn't fix it.

Re: After updating Galaxy S9 to android 9 WiFi calling no longer works

i think samsung changed the wifi calling threshold. i noticed that since i moved to Pie (android 9) on my s9+ that wifi calling isnt active as much. this looks like its because i have a strong 4g signal at home. if you go in to mobile connection settings and set the phone to use 2g/3g (not 4g / lte) then wifi calling should kick in. at least thats what i found. at first i was a bit annoyed but it makes sense.

I have just got a software update today and same thing for me wifi calling has disappeared. Thing is I really need it in the house as we have a terrible signal. I read the fix above to turn off 4g, so does this mean that every time you leave the house you have to turn 4g on and off again?

Re: After updating Galaxy S9 to android 9 WiFi calling no longer works

The only way I can make it work reliably is to turn on airplane mode, then turn WiFi back on. Then, turn airplane off when I leave the house. I've setup activity in automagic to alert me when I disconnect from home. Pain in the bum. I have a oneplus 5t, and I've seen the same problems on Nokia, so I think it's by design in Pie sadly.
