Probably a minor thing to worry about but when I power on my Maxx the "droid" sound effect is barely audible. It used to be fairly loud. I wondered if an app was causing this so I did a couple factory resets after the ICS update. After the 2nd reset I only loaded the apps back on that I consider essential. I've seen some posts about clearing the cache from the phone and don't really understand what that is or more importantly is it necessary when doing a factory reset? Maybe its nothing to worry about but I wanted the be sure there isn't an app leaving behind something that can be cleaned up. Thanks in advance!
