Help What is the tiny hole next to headphone jack on the top?? Another mic?

taylormah · Apr 4, 2011

I noticed a tiny hole, similar to that of a mic, on the top of GS2. Is it a mic as I am thinking (for noise reduction maybe??) or something else?

Here is a picture:

probably a sound cancelation mic

Hey,

on my phone it looks like there's a tiny little white stone stuck in there. But I'm really not sure. How does it look on your phone? I can't really tell from the picture above...

Any help appreciated. I'm kinda worried that something's stuck in my phone...

It is a sound cancellation microphone, works in parallel with the one on the bottom of the phone.

Yeah, I got that. But does it look like there's a tiny white stone in there on your phone, too? Or is it just a black hole?

Mine Doesn't have any white stone in it, just looks black inside

On the user guide I have it says that it is a "mouthpiece" I presume by that they mean a microphone that is only active when you use the speakerphone feature or record videos. Hope that helps.

Damn. So I guess I have to find a way to get that thing out of there...
Thank you.

Yes, mine is just a black hole too - no white stones. Sorry!

That is the microphone.

If there is some debris (like the white stone mentioned) remove it with a tweezers immediately.

b1ermann · Jul 21, 2011

Ok, I think I really have a problem. The stone is stuck in there. I tried getting it out with a thin needle but that wouldn't work. The stone fits the hole perfectly... Any ideas how I can get it out of there?

You could try a bit of vacuum using your mouth?! May be safer than sticking a pin or something in - it may push it further in? Sounds like it may have happened when you wiped it over - it's not a small piece of packaging foam is it which is actually a good sound insulator :-(

It's for recording audio during video recording and loudspeaker.

Hi guys, and does anyone know what the big hole on the left side is for, the one next to the volume rocker button?

That's for a carry strap.

email manufacture with model and date purchased, maybe it's supposed to be white, but I doubt it.

Then the thread should have been deleted 7 yrs ago!

The information posted years ago might still be relevant for someone. Your post might be helpful as well. I didn't remove it. I did want to advise and inform you that the tread is quite dated being as you are new to the site.
