Question

Android Pie Wifi Calling has one-way audio only


I have a Pixel 3a running Pie and wifi calling doesn't work. In particular, inbound calls to my phone (over wifi) result in audio only going *from* my phone to the caller, but not the other way. Turning off Wifi cures the problem and allows  me to return the call.

 

This happens on two different Pixel 3a's on two different networks -- so it doesn't appear to be specific to the phone or the network.

 

Does anybody else see this problem? From reading other threads here, it seems that it is different to the other wifi calling issues (though there is an iPhone issue where the audio channel goes one way after five minutes).

Hey, Philip!

I'd have to agree that this issue sounds different than other WiFi calling issues I've read about as well. On the two WiFi networks that you tested, did you have any other issues besides the one-way audio? Has this been going on since you've had the Pixel 3a? Or did it just recently start? We may need to file a ticket with our Engineers to put this on their radar and see what needs to be done to get the audio fixed.

Good morning, @magenta2128671​! Just checking in to see if you had any questions after reading over my previous reply. 😊  

This same issue is happening with my 3a.  All other phones I've had had no issues with wifi calling, this is the first time.  I answer and just no audio.  I need to turn off wifi and call them back in order for it to work.

It's odd that this is happening on your device as well, @chrisavs​. Did this just randomly start or did you recently update your phone? How long has this been going on for? Lastly, have you already worked with Tech Support to see if a Trouble Ticket needs to be filed?

My wifi calling botton all together disappeared after J7star Pie update. So bottom line TMobile no longer offers free wifi calling in their phones. The advertisement is false.

I’m having the same issue with a Pixel 3a, Wifi calling is worthless to me as a result.  Always have to turn it off and call back the caller as I cannot hear them.

Excluding the potential of it being a bandwidth issue on both networks, which I can guarantee aren’t an issue in my situation thanks to Gigabit internet here.  Updates for all devices, including OnePlus, Samsung, and many others have introduced WiFi Calling and VoLTE connectivity issues with recent updates.  Some of us, myself included, rely on WiFi Calling when roaming and even at home.  The most recent updates to the OnePlus 7 Pro (NA and T-Mo) and 8 5G all are experiencing these issues.

I am having the same problem with my One Plus 7t Pro for the last week or so.

i am having a similar issue with my OnePlus 8-5G phone. Restarting wifi or rebooting the phone has no effect. calls i receive over wifi have no audio.

I have the same issue on Pixel 3a while on wifi calling. The call goes through other people can hear me but I cannot hear them. It used to work fine until several months ago. Rebooting fixes it for a while but then the problem recurs.

Has anyone found a solution? Could it be something with the google carrier services app?

Thank you

Just got T mobile and a OnePlus 8 (Android 10) three days ago. Wifi calls connect quickly but I can't hear a thing from the person I called. I have 100mbps internet that works great for everything else. Reboot doesn't help. 

I have noticed when I attempt a call, it hangs at first, then connects by automatically turning off wifi calling. Once I finish the call, wifi calling automatically re-enables itself.

I've had this exact issue on every T-Mobile OnePlus device I've had - 8T, 7T Pro 5G, 7 Pro, 6T. I've used different SIM cards, different networking routers, to no avail. Restart usually fixes it for sometime until it stops working again.

With the OnePlus 8 5G.  This was one of the known bugs to make it into the update a few days ago, which also exists in the current 7 Pro and 7T beta firmware for the Android 11 updates.  Android 11 has changed how WiFi Calling works slightly.  Hopefully a fix will make it into the 8 5G's next update and will hopefully be fixed before the final Android 11 update is pushed to the 7 Pro and 7T.

As I just explained, I've had this issue consistently on Android 9, 10, and 11.

Well, that tells me it’s your connection in some way then.  I have no issues on my two OnePlus 7 Pro’s, 8T+ 5G, Samsung Galaxy S9+, or my LG V30.  

My wife's relatively new oneplus 8t is experiencing this same problem where she can not hear the person on the other side of the call.  The caller can hear her.  Shutting off wifi calling seems to resolve the issue.  She's only began noticing this issue this week.  She's had the phone for 6 weeks.  Has a fix been found?

Exact same issue here with a Google Pixel 4a 5G. Not sure exactly when it started happening, but every time I receive a call recently I can’t hear the caller until I turn off wifi. As soon as I do, the caller can be heard almost immediately. They can hear me throughout the call without issue. Very frustrating when working from home, usually in a basement. Luckily I do most of my work calls through Teams and personal calls through Hangouts, neither of which have audio issues in either direction. 

Same here on both my wife’s and my Pixel 5.  Reboot fixes for a short period of time only.

Same issue - Pixel 5.

Same issue here on my Google Pixel 5 on Android 11 Build Number RQ2A.210305.006. Was even happening on previous build.

If a call is placed or received on WiFi I can not hear the other person. If I turn wifi off mid call, then I can hear them. Per the other person on the call, they can hear me the entire time.

I have WiFi call settings to “Call over mobile network: if Mobile network is unavailable, use Wi-Fi”. I do have mobile network coverage during these calls and looks like it’s still attempting to do it over wifi.

Ditto - Pixel 4a 5G - also could be in a network call, it switches to WIFI call mid call and looses caller audio (aka they can hear me, I can’t hear them).  Very annoying!

for those of you with Pixels, was this EVER working?  We just moved to tmobile so only have a perspective of the last few weeks.

Yes, it works great on my Pixel 3 (even today), but my wife has the Pixel 4a 5G and it’s totally flaky.  After screwing around with WIFI Calling on primary, on secondary (aka network primary), and totally off, I believe there are 3 issues:

  1. the 4A 5G is not honoring my choice to use WIFI calling primary - makes network calls when it shouldn’t.
  2. Attempting to transfer from network to wifi call is resulting in loss of caller audio (caller can still hear me)
  3. Transferring from 5G to 4G similar issues with caller audio disappearing.

Again - same WIFI network, my pixel 3 always chooses WIFI calling and it works just fine.  Unfortunately, between google & T-Mobile, neither is acknowledging my findings :( 

My Pixel 4a5g also has this issue. It didn't initially when I got the phone. I wonder if one of the Android updates messed something up. It seems fairly random for when I can and can't hear the other end. Pretty frustrating as I work from my basement and was able to make crystal clear calls for a while and now I keep getting embarrassed when I need to call 3 or 4 times before someone can hear me.

I disconnected google voice and those similar issues seem to be resolved.
