i have a v300 and myne has that sound as well...the only way i know how to do it is to use a seem editor and mess with ur phone through ur computer...u can adjust what the external screen says when the ur phone is open...increase the volume for the earpiece as well as the external speaker..and stop the moto sound as well as insert different animations on startup and shutdown..it is very complicated though and u need a usb cable...if u want more info let me kno, but i doubt u want to do this **** 😛
