My EVO is too loud on both speaker and bluetooth headset. I have all volumes turned all the way down, including the headset. Sometimes on the headset it ramps up all by itself, then goes back down. In the two years I had my Instinct (I know) the headset never did this. Using the phone only the speaker sometimes distorts on a call it's so loud. Phone is unrooted. I've applied all updates. I've adjusted all settings. Any ideas? Thanks!
