Its well known that the Razr Maxx has a speaker problem. I have noticed that with my otter box defender series that the problem is worse. I have tried running my finger from the middle of the phone to the end of the speaker with the otter box on (the known speaker fix) but it does not work. I have had to take off my otter box since I can not use the speaker. Does anyone else have this problem and does anyone have a fix?
