Speakerphone on T-Mobile Phones

[dhski04]

Whenever I try to use speakerphone for phone calls, the person I'm calling can't understand me. I believe it must be some sort of software issue as it has happened on both an S9 and A71 5G, and on both phones I can use speakerphone with Duo or similar apps and have no issues with speakerphone. I use T-Mobile. Any ideas?

I have a Pixel 6 and LG V60 and my wife has a Samsung note 20 ultra and we are both on Tmobile and no issues w/speakerphone.

Welcome to Android Central! Are you using a case? If so, does it happen without the case?

Also, see if there's a Noise Reduction option in the Phone app's settings.
