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

| 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
- Is this a known issue with Teams Android on Samsung Galaxy A36 devices?
- Has anyone seen similar behaviour with One UI 8.5 or Android 16?
- 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.
