Just so you know guys,
My BV8000 pro reboots randomly - with no startup sound.
I don't know why it doesn't - but it doesn't.
It's possibly because I turn the ringer to vibrate only for ringtones, and DND mode overnight... But yeah.
Still - this fault is hideous. I've never had a mobile phone in all of the nearly 20 years i've owned a mobile phone, that regularly reboots itself at seemingly random moments.
