Hello. My BV9500 Pro is releasing, since some months ago, the sound from both speakers (earpiece and rear loudspeaker) while it should only come out from the rear loudspeaker. While making a regular call, there's not a problem, the earpiece works fine and the proximity sensor too. The problem is coming while listening to music or watching a video, the sound is coming from the earpiece and the loudspeaker at the same time, like as if it'd be stereo mode. I can't modify this output from the Configuration. Does anyone have a clue about it?

You can have a try to reset the sound: Go to the dial interface and dial "*#87#".
Or you can contact our professional after-sales directly.

Hello. Thanks for your fast reply. Unfortunately, once I dial *#87# nothing happens, it's not taking me to any menu or action. Are you sure that's the right ussd code?
