Thank you for your support of Xiaomi products. The Xiaomi 15 is designed to provide an immersive gaming experience and uses multiple microphones (top and bottom) for voice input during gaming sessions. These microphones work together to capture your voice clearly, ensuring high-quality communication while you play.
However, if the microphone holes are occasionally blocked or partially obstructed during gaming (for example, by fingers or other objects), it can lead to fluctuations in voice transmission, such as the recipient hearing no sound or experiencing friction noises. This is a normal phenomenon and is related to how the microphones are positioned and how they capture sound during movement or specific gestures in the game.
