We are investigating a Microsoft Teams audio issue on a Samsung Galaxy A36 and would like to know if this is a known issue or if anyone has seen similar behaviour.

Environment

  • Device: Samsung Galaxy A36
  • OS: Android 16 / One UI 8.5
  • Teams Version: 1416/2026.27.011
  • Multiple Wi‑Fi networks tested (office and home)
  • Issue occurs on different access points and internet connections

Problem** **Description

When making Teams calls using the Android Teams app and the phone's built-in microphone, the remote party reports that the user's voice is:

  • Crackly
  • Muffled
  • Low pitched
  • Difficult to understand

The user does not hear any issues themselves. The problem only affects the transmitted audio heard by the other participant.

Troubleshooting** **Performed

✅ Battery optimisation disabled for Teams

✅ Wi‑Fi power saving disabled

✅ Teams noise suppression disabled

✅ Teams cache cleared

✅ Teams Developer Preview enabled

✅ Tested on multiple Wi‑Fi networks (office and home)

✅ Tested on 2.4 GHz Wi‑Fi

✅ Reproduced on multiple outbound Teams calls

Results
Scenario Result
Teams app + Wi‑Fi + built-in microphone Poor audio
Teams app + Wi‑Fi + Bluetooth headset microphone Good audio
Teams app + Mobile Data + built-in microphone Good audio
Teams via Edge browser + Wi‑Fi + built-in microphone Good audio

Because the same device microphone works correctly in both the Edge browser and on mobile data, and a Bluetooth microphone works correctly within the Teams app, the issue appears to be specific to the Teams Android app when using the handset microphone over Wi‑Fi.

Questions

  1. Is this a known issue with Teams Android on Samsung Galaxy A36 devices?
  2. Has anyone seen similar behaviour with One UI 8.5 or Android 16?
  3. Are there any Teams media, audio-processing, codec, or Wi‑Fi-related settings that could explain why only the handset microphone path is affected?

Any suggestions would be appreciated.

    Hi Simon,

    Thank you for providing such detailed test results. The comparison between the built-in microphone, Bluetooth headset, Wi-Fi, mobile data, and Teams in Edge is particularly helpful in narrowing down the issue.

    At this time, I could not find any official Microsoft documentation confirming this as a known issue specifically affecting the Samsung Galaxy A36, Android 16, or One UI 8.5. Therefore, I would not classify it as a known issue at this stage.

    Since the built-in microphone works correctly when using Teams through Edge over Wi-Fi and when using the Teams app over mobile data, the microphone itself does not appear to be the general cause. Based on your testing, the behavior seems to occur specifically when the Teams Android app uses the phone's built-in microphone over Wi-Fi.

    Since you have already completed extensive application and network troubleshooting, I would suggest trying the following:

    1. Make sure both the Teams app and your Samsung device software are fully up to date.
    2. Completely uninstall Teams, restart the phone, and then reinstall Teams from Google Play. This provides a cleaner test than clearing the app cache alone.
    3. If available on your device, temporarily disable Samsung audio-processing features such as Dolby Atmos, Adapt Sound, voice effects, or other microphone/audio enhancements, and test another Teams call.
    4. If the issue persists, I recommend asking your IT administrator to open a support request with Microsoft. When submitting the case, include the Teams version, Android and One UI versions, the time of an affected call, participant information, and the comparison results you provided above. This information may help Microsoft Support investigate the issue further. For more information, please refer to: Get support - Microsoft 365 admin

    In the meantime, based on your testing, using a Bluetooth headset, mobile data, or Teams through Edge may serve as practical workarounds.

    I hope this helps point you in the right direction. If you have any further questions or updates, please feel free to let me know.

    Best regards.

    Hi @Simon Laffoley same problem in our company. We have heart that the next firmware update of Samsung should solve the problem. It was scheduled for this month, now it is postponed to January. And bad news it is not clear if the installed Android version will get the update in January. We either must look for new device for our company or we pray and hope that A36 and A27 will get the promised update.

    Hi Kristen

    I completely factory reset the phone ad did the absolute minimum to get teams on and working. Its on Latest OS update and Teams. I have tried disabling Dolby Atmos, and all the other microphone/audio features, and the Teams call was still poor.

    I can see from the answer from @bdiepold that it could well be a Samsung firmware problem that will not be resolved this year. We will next try a non-samsung device, like a mid-range Oneplus or Poco to see if it is manufacturer specific.

    I'll update here in the next week or so with any news

    Thanks for the info
