When I turn on my BV9000Pro phone at night, awake my whole family. The musical jingle is really loud and troublesome. It would be great if it were released, a firmware update, and this feature was removed. May be in the future?

I already told our software team a few times. The only solution I know until a fix is to insert the headphones before re/start the phone.

Turn off BesLoudness.
Speaker sound volume will be normal and sound is soft and nice.

On BV6000 and BV7000 power on screen was ok but it starts on model BV8000 Pro and you can make some utility on settings to change the welcome/power song. It will be great to mute this logo song.

Thank you
