I can hear audio on only one side with my earphone. Why?
Symptom
I can hear audio on only one side with my earphone.
Cause
If you hear from only one side with the earphone that came with the cell phone, Sound Balance may be the reason.

Go to Settings > Accessibility and check Sound Balance. Make sure the slider is in the center.
If not, move it left or right to balance the audio.
