Not the one to eject the sim. There is another hole, is that another mic?

Yep, for noise cancelling. See specs:
- Active noise cancellation with dedicated mic

The hole in cases on back top right corner is for what?

Does anyone know what the hole is for on the top right corner on the back of the GN? Images below. You can also search for cases on Ebay and it is on all of them.
Noise-cancellation mic.

I don't see a mic hole on any of those pictures. And if you look at the second picture, it almost looks like a camera.
No GN I've seen so far has a mic in that location and that would be a pretty bad location for it.

Oh, yeah, a camera, that's it... No clue what that big ole thing an inch away is, but that tiny hole that you didn't even see - yeah that's a camera...
And please do tell why that would be a horrible location for a mic?

I never said it was a camera. I said whatever is behind that hole in the second picture just looks like one, alright? Cool.
And if you are on speaker phone and you place your phone down the noise cancelling mic is obstructed. Not that hard to realize honestly. Also, many people put their index finger on the top right of the phone when they hold it to their ear.

If you put the phone down in the way you describe you would also be obstructing the speaker... Most people set the phone with the speaker up for that.
I cannot fathom holding my phone in a way that obstructs that mic, however, even if i did, I would still have a regular phone call...

What's odd about it?
If it is a noise cancellation mic then its in the perfect position so I would back that theory. Up against the ear it would pick up surrounding sounds to minimize external sounds, in speakerphone operation (screen face down) it would act the same way and as the phone is quite long very few people would put their finger over the top of the phone to obstruct it.
Mark.
I think its the speaker.

Between the click of the light and the start of a dream.
Its probably the barometer. I'm surprised I am the first person to say it.

You don't need a dedicated hole for the barometer. Any whole anywhere would do.

The barometer doesn't need a hole. It can just be inside the phone. It doesn't need a specific port to measure pressure. The pressure in the phone is the same as outside the phone, and there are plenty of ports on the phone already (the inside obviously isn't air tight).

LOL. That would be awesome, but the hole is way too small for the lanyard though
and it would need 2 holes for that
And its at the wrong end of the phone lol.
Mark.
just for reference, on the SGS2
the mic is at the bottom, and the noise cancellation mic is at the top, pretty close to where the opening of the GN case is showing
so i wouldn't be surprised if there's really a NC Mic in that location
after all it's just a pin hole, i don't think those pics are high quality enough to show it

Tiny Hole On Top Left of Phone?

So, I might of been quite tired and not concentrated when this happened...
But, I was removing my SIM when I realised that I was actually inserting the SIM opening tool into the tiny hole in the top left not the top right. Does anyone know what this hole is exactly for?
I was thinking it was either a microphone (wrong end of phone?) or some sort of water damage detection hole?
Either way it definitely didn't open my SIM slot

I believe it is another mic for stereo video and background noise cancelling when phoning

i personally think its a mic for calls to help when on loud speaker
that would be the secondary microphone for noise cancellation
Thanks for your help guys, I just hope me prodding it with the HTC Sim tool has not broken it haha...
I too wasn't concentrating in the store when they were giving me the sim, i'm pretty sure it's a reset button as the phone restarted when I poked a paperclip in the wrong hole.
I did exactly the same thing yesterday. Wasn't concentrating properly. I pushed it in pretty hard too. Have you noticed any problems since in call quality or video sound?

Noticed that many say the hole is for a microphone. After searching I cannot find that mentioned by HTC anywhere.
However beneath that hole is a push button switch.
I don't what it is for and am willing to try, however recently my phone decided to become a brick, so after that is fixed...... :good:
little hole
its is a mic i damaged my bottom one so i opened my hox to repair and its the very same as the mic i replaced

My First thought too !

[Q] What are the 2 tiny holes on the SGN2?

Hello. What are the two tiny holes symmetrically placed at the top and bottom of the Galaxy Note II? I'm having a International GT-N7100.
The top one is situated just right to the ear-phone jack. The bottom one is to the left of the USB port. (When looking at the unit from the front aspect.)
Thanks for any information.
both are mic
Thanks for the information.

[Q] No sound in call

Hey guys,
I am having problems with a htc one x after repairing the display and digitiser.
First of all the repaired worked like it should but I noticed the top and bottom speakers didn't work afterwards... So I opened it up again and noticed that I placed a piece off tape over some connectors of the speakers at the bottom, so I removed it and i had sound again, but now for some reason there is no sound while calling... Anybody knows if the call speaker is the same as top speaker and which connectors are used for the call speakers? Cause there is no sound at all... Although the other side of the call does here everything, so the mic is doing fine.
Greetings

Nvm, problem solves, i forgot to take out the earphone from the old casing for the screen and place it in the new casing

Microphone placement on international version?

I have the 4gb / 64GB dual SIM version, and it seems 99% of the cases I buy do not have the microphone hole in the correct spot, it blocks the microphone. Is the microphone placement different on the dual sim G7 power? The only case (out of 6 or 7 I've tried) that has correct microphone placement actually has 2 holes over there, one of which is correctly positioned on the microphone.
* deleted *
excuse me ?
I just used a dremmel tool to grind the hole bigger to open it up over the mic hole.
Wow, drill holes. Mine's from Brazil, it's to the left of the charging port. Not that it matters after 10 months.
