Receiving Calls on Android not ringing

PaulTW 

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
