Receiving Calls on Android not ringing
Thanks Paul, this sounds like a bug for this particular device (Galaxy A03s). I have raised the Bug here:
Bug: Incoming calls not ringing on Galaxy A03s · Community (microsoft.com)
If you could
1.) Raise a support ticket via the Microsoft 365 admin centre
2.) In this thread put down the build numbers of the Teams App and the Galaxy AO3s
I will raise this to Microsoft engineering to review tonight. Of course, it could take a while to resolve but at least we are pushing it in the right direction. Thanks for providing all the information.
Hope this has answered your question
Best, Chris
We have exactly the same experience on our Xcover 4 (SM-G398FN - android 11) and 5 (SM-G525F - android 11) as well as on our Xcover Pro (SM-G715FN - android 12). We have also disabled any possible setting regarding battery optimisation on Teams and Wifi ! For WIFI, we disabled battery optimisation by excluding 3 background WIFI services from battery optimisation. The latter reduces the frequency substantially on missed calls after some idle time. It does not completely eliminate the problem however.
One can do this via Apps -->Special Access (via 3 dots) --> battery usage optimisation --> select ALL apps --> filter on "wifi" and you will see 3 android system services: disable battery optimisation for all 3
As this does limit the missed calls while not seeing nor hearing them, occassionally the problem occurs again.
Samsung is aware about this problem and the root-cause is the combination of the WIFI chipset and the supporting firmware. They are currently testing an improved firmware for which we hop to see succesfull testing next week.
Thanks for your reply!
How about Android 13? No issues for you there?
The settings you describe are also available in Android 13, but through a slightly different route. There were 7 apps even with 'wifi' in its name. I put them all to 'Unlimited' for battery optimisation. Now wait and see if it has effect...
PS: we also experience the issue on 4G. So I doubt this will be a full fix. But any improvement is welcome.
And would love to hear the outcome of the new firmware test next week (or later..)!
This seems to be a common problem and is darn annoying as it prevents you using a mobile phone as a cheap reception handset. I've been helping a charity set-up a Teams call queue which rings two users/mobiles at once. They report that the phones don't ring and it goes straight to voicemail.
I'm currently testing it with Teams app on PC and on another mobile. If the screen is off (locked), then it rings on the PC immediately but can take 5-10 seconds to wake up the mobile. At which point it reaches time out and flips to voicemail. The phone I'm testing with is old. Will try with their brand new Xiaomi phones in the office after the bank holiday weekend.
- Do we know if the WiFi firmware update was released? We're still having the same issues.
- We are not using any android 13 based smartphones and we are also very curious about the outcome of the new firmware. I will keep you posted !
