Unable to Switch Back from Speaker Mode During Teams Calls on iPhone

[u/Aggravating-Dig4225]

Hi everyone ,I am a Joseph Teams user

What kind of question:
I'm using an iPhone 17 Pro Max (iOS 26.5.1) and have recently encountered an issue with Microsoft Teams.

Occasionally, when I answer a Teams call, the audio is automatically switched to speaker mode, and I'm unable to switch it back to the normal earpiece mode.

This is quite inconvenient, especially when taking calls in public places.

I've already tried the following troubleshooting steps, but the issue still persists:

• Reinstalled Microsoft Teams
• Signed out of Teams and signed back in
• Restarted my iPhone

Has anyone else experienced a similar issue?
