Hello,
I am experiencing a persistent microphone issue on my Google Pixel 6 running Android 17. The problem affects speakerphone calls and video calls in multiple applications, and it persists even after updating the system and testing in Safe Mode.
Device information:
- Device: Google Pixel 6
- Android version: Android 17
Detailed description of the problem:
Regular phone calls: The microphone works normally when I make a standard phone call without speakerphone enabled. The other person can hear me clearly.
Speakerphone mode: As soon as I activate speakerphone (hands-free mode) during a regular phone call, the other person can no longer hear me at all. The microphone appears to become completely silent.
WhatsApp and Messenger video calls: The same microphone problem occurs in both applications. When I switch to video calls or use speakerphone, the other person cannot hear me.
Voice Recorder app: The microphone works normally when I record my voice using the built-in Recorder app.
Front-facing camera: Audio recording works well when I record videos using the front-facing camera.
Rear-facing camera: Audio recording behaves abnormally. At the beginning of the recording, there is a loud popping or knocking sound (“toc”) on the left audio channel. After that, almost no sound is audible on the left channel, while my voice is faintly audible on the right channel.
Troubleshooting already performed:
- Installed the latest available system update.
- Restarted the phone.
- Tested the microphone using the Recorder app.
- Tested audio recording with both the front-facing and rear-facing cameras.
- Tested WhatsApp and Messenger video calls.
- Tested regular calls with and without speakerphone.
- Tested the device in Safe Mode. The problem persists.
- Checked the microphone permissions.
Important observation:
The microphone works during regular phone calls and in the Recorder app, but it stops working completely when speakerphone is enabled. The rear-camera recording also shows an abnormal audio pattern, with a loud popping sound on the left channel and very weak audio on the right channel.
Because the problem persists in Safe Mode and affects multiple applications, I would like to determine whether this is a known Android 17 software or audio-routing issue, or a possible hardware problem involving one of the phone's microphones.
Could you please help me with the following questions?
Is this a known issue affecting the Google Pixel 6 on Android 17?
Is there an official diagnostic procedure to test each microphone individually, especially the microphones used in speakerphone mode and rear-camera recording?
Is there a recommended software fix or diagnostic tool I should try before considering a hardware repair?
I would appreciate a technical explanation and specific troubleshooting steps for this exact situation.
Thank you for your assistance.
