What if the volume of Gionee's mobile phone is low?

First, the volume is low when talking;

Press the Volume+key during a call to turn the volume to the maximum. If not, it is the receiver's own problem. I suggest repairing it.

Two: when playing music, the volume is low;

Turn on the music, play a song at will, and turn the volume to the maximum;

Go back to the main page and click "Settings";

Find "More Settings" and click Enter;

Click "Accessibility";

Turn on "Mono Audio" and immediately feel that the volume of the mobile phone has doubled.

PS: This function will combine the dual-channel volume of the mobile phone when playing music. Because mobile phones generally have only one external speaker, it does not affect the dual-channel playback, but has the effect of increasing the external volume.
