Why are the upper and lower speakers of the POCO M7 Pro 5G different in volume?

Thank you for your support of Xiaomi products.
If the sound volume is different between upper and lower speakers of the phone, please refer to the following details:
1. The POCO M7 Pro 5G is equipped with asymmetrical stereo speakers, designed to provide an immersive audio experience;
2. However, due to the intentional structural differences between the upper and lower speakers—such as size, positioning, and internal components—the sound output will not be perfectly balanced, and you will notice a slight inconsistency in volume between the two speakers;
3. This variation is a result of the hardware design and is completely normal. It does not indicate a defect or quality issue, and the overall stereo sound performance remains clear and enjoyable for everyday use. This phenomenon is not a quality problem of the product, please feel free to use it.
