Why can't the other party hear the voice in the POCO F7 Ultra when playing games?

Thank you for your continued support. The POCO F7 Ultra has undergone strict professional inspection before leaving the factory, so you can feel free about the performance and reliability of your device, knowing that it has been thoroughly tested for quality and functionality.
First, check whether the phone case is blocking the MIC. And then, check whether the MIC hole is dirty. You can try to wipe it gently with a dust-free cloth to remove it. Finally, check if your finger covers the microphone when playing in landscape mode, and try changing the holding method.
