Why is the receiver volume on the POCO F7 Pro low on a call in handheld mode?

Thank you for your support of Xiaomi products. Mobile phones undergo strict professional inspection before leaving the factory, so you can use them with confidence.
To improve the experience, you can try the following:
1. Check if the phone's protective case or film is blocking the MIC. Remove the case and test the microphone again;
2. Check whether the MIC hole is dirty or blocked. It is recommended to use the volume+ button to confirm the sound volume during a call;
3. When making a call, adjust the position of the phone so that the receiver is closer to your ear. Try to hold the phone at a different angle;
4. If you're using your left hand to hold the phone and the receiver feels off, try switching to your right hand. This can help align the receiver with your ear more effectively.
