My Lord, how can you turn up the volume when it is low?

1: Turn on mono audio settings.

We can go to the phone "Settings", find "Smart Assistant" and then click "Accessibility", and finally turn on "Mono Audio".

Operation mode: Settings-Smart Assistant-Accessibility-Mono Audio

2. The role of mono audio

This function will combine the two channel sounds of our mobile phone. Generally, a mobile phone has only one channel for putting a speaker. This setting will not only affect the playback of two-channel sound, but will increase the sound of the mobile phone.
