GS3 Mic Problems?

[Anonymous]

Anyone having problems with calls?

I've had my S3 since June last year and it's been fine until yesterday. When making or taking calls, I can hear the caller clearly but they can't hear me.

I've noticed if I hold the phone's mic right against my lips flat in my hand and shout directly into the mic (kind of like an elderly person who's confused about phones would lol) they can fainly hear me but when holding the phone normally and talking normally, the sound is too quiet to pick up.

I've tried Noise cancellation on and off, made sure mute is not activated and tried extra volume on and off. None of it helped,

Any ideas anyone?

I'm guessing there isn't something obvious I'm missing where I may have changed a mic setting somewhere?
