Recently, every time that I use my Droid Razr M's speakerphone, it sounds like someone is either underwater or far away. The volume is turned up all the way, the Audio Equalizer is on Vocalizer, there is no dust on the phone or Otterbox Defender Case, and it's never been dropped.
It is 2.5 years old and I use it frequently. To not be able to hear the person I'm talking to is really annoying.
Any suggestions? Did everything except factory reset....probably don't want to do that just yet and nothing that I've done has fixed the issue. Ringtone volume and call volume non speakerphone is great!
