microphone
The microphone is not working in any kinds of phone calls. They can call but I can't hear any sounds from the other and vise versa. Also if I record video, there's no sound. And some of the my mobile applications that needs microphone doesn't work and the app/s collapse. I also reset all settings but still nothing happened. I don't know what to do. I hope someone can help me with my concern.
