I have a Droid X and my husband has the X2. Recently, his notification and ringtone volumes have been so low, he has been missing his calls. I've double checked to see if the volume is all the way up, and it is. Media, notification, ringtone volume is all the way up. Still, too quiet, even when switching to other ringtones. I tried powering it off and removing the batter, re-inserting and powering back on, but it did not fix the problem. Is there a way to troubleshoot this?
