Anyone else had any issues with their external speaker not working? Speakerphone, any media sounds, ringer sounds - not working. (The normal phone speaker does work though so if I get a call, I can hear through the small speaker at the top of the phone). I've tried turning off bluetooth to make sure it wasn't connected to something, nothing is in the headphone jack, etc. Phone hasn't been dropped or anything - just had the speaker stop working suddenly a few days ago and very frustrating that I can't get any external sounds to work. Relying on vibration for notifications, rings is not very effective for me. Any thoughts, ideas, suggestions would be appreciated! Thanks.
