If you notice this phenomenon when using the phone, please refer to the following information:
1. The POCO F7 Pro uses dual stereo speakers, and there will be a stereo centering effect when the phone is placed horizontally;
2. The whole device adopts an asymmetric design with an upper speaker and a two-in-one receiver and a separate BOX for the lower speaker;
3. If you feel that the volume of the upper and lower speakers is inconsistent, please first rule out whether the phone's film, leather case, etc., are blocking the receiver;
4. And confirm whether the position of the phone speaker is dirty. You can try to wipe it gently with a dust-free cloth to remove it;
5. If you are not satisfied with the stereo centering effect when the screen is horizontal or vertical, you can search for [Hearing] in [Settings] and slide the [Audio balance] setting on the interface to adjust the stereo centering effect.
