Why are the upper and lower speakers of the REDMI Note 14 5G different in volume?

Thank you for your support of Xiaomi products. The REDMI Note 14 5G has undergone strict professional inspection before leaving the factory, so you can use it with confidence. It is designed with asymmetrical stereo speakers. The structural design of the upper and lower speakers is different, resulting in inconsistent sound volume. The volume balance setting in the system is not be adjusted to the optimal state, which can also cause inconsistent volume between the upper and lower speakers. This is a normal phenomenon. It does not affect the normal use of other functions of the phone.
