S4 Microphone Problems

[oafc]

People can't hear anything I say in calls - my microphone doesn't work. However when I go onto speaker mode they can hear me perfect. I can record voice memos and S Voice works fine. What would be the cause of this problem? I have upgraded firmware and done a hard reset. I've also turned noise reduction and extra volume on and off. Is my phone faulty or is there a simple fix to this? Thanks

Is there any way of disabling earSmart?

I noticed I was covering the microphone sometimes while holding the phone... The microphone is on the right side on the galaxy s3, I am a righty so I would hold it on the left side if that makes sense, now I need to get use to holding the right side not the cover the microphone since its on the left side now. I really dislike when company's chance little things like that, no biggie but I need to change my holding habits on it. :-\

I had this issue on one of my phones but only if held it in my left hand. So I looked in the mirror only to find my finger covering the mic.

Hi everyone. My first post and I know this is an old thread, but I had this exact problem with my galaxy s4. Speaker phone worked fine, but when I talked on normal calls no one could hear me.

long story short, I fixed mine and it was very simple.

There is a tiny little hole at the bottom of the phone. Im pretty sure this is the hole for the bottom mic. Somehow some kind of gunk was clogging it up. I took a syringe and dulled the needle (so as to not damage anything.) And I stuck it into the hole just enough to suction out a tiny little piece of gunk that was blocking the hole. After that gunk was cleaned out, it worked like new.

so if you are having trouble with people hearing you during phone calls, yet your speakerphone is working fine, try cleaning out that little hole. Be very careful not to damage anything or push crud further down into the hole. A dull hypodermic needle worked well for me, but again, be very careful.

hope this helps.

It actually helped, my microphone was also stucked with dust

There is a microphone at the top near the earphone and at the bottom to the left of the micro usb plug! These are very small holes and can be easily plugged with dust, food, belly button lint etc. Please be careful cleaning these out because you could damage the microphone.
