I have a T-Mobile 8320. I am sure I didn't adjust anything. Currently, there is no audible sound coming from the speakerphone whatsoever. My incoming call ringtones won't sound and my speakerphone won't work.
Checked my profiles and they're still the same, meaning nothing is set to mute.
I also tried to use my default media app to play a song using the speakerphone, but no sound. When the speakerphone is off, I can hear the song through the headset, but nothing when pushing the speakerphone button.
Has my speaker phone/external speaker gone capute?
My 8320 is just 6 months old.
