Regarding the 3 small holes on the back of the Sensation.
My guess is 2 mics for stereo recording with video and one for noise cancellation for calls.
Any case that blocks these, like the TPU from Amzer, would be a fail.
Is that the purpose of the 3 small holes on the backshell?
As far as I can tell they are for noise cancellation, but sounds feasible to be for recordings.
I thought they are there for the antennas....
Should be easy to figure out. I would but I don't have a Sensation yet.
Block one with something like a piece of tape. Record a video and see if you loose a channel. Repeat the same process for the other 2. If you loose right audio on one, left audio on another an nothing on the third, first two would be for stereo audio and 3rd for noise cancellation.
Antenna! Take the cover off and lose all signal... The hole are how the metal tags are connected to the case, kind of like riveted to the case. Looks like one deliberate hole near the speaker though

Ok. Of course we know the antennas are built into the backshell.
Although, have you ever seen a phone with holes for the antenna?
if you look at the pics at the bottom of this review it'll confirm that their for the rivets holding the antenna contacts. also seems the US version has 1 more contact point than the EU version, by the speaker.

my question is where would the second mic be?
Yup I can confirm the there are two holes that hold the connectors for the antenna (or at least the two coppery parts on the cover. The one near the speaker is just a hole, with plastic underneath it, can't say for sure if this is for a second mic that makes the video stereo..

in the link I posted you can see on the US version that one is also used for an antenna connection. I wonder why the US version has 1 more connection than the EU one.
even the standard HTC produced Sensation rubber cover I bought from the TMO store has all those holes covered except for the one near the camera lense. If I had to guess, I'd say the other holes are purely for the antenna anchors, while the anchor for the lense is also a hole for a mic. That one could certainly be for noise cancellation during phone calls while doubling as a mic for the right stereo channel
If you take off the back cover you can see where every hole is, there is a corresponding antenna anchor point... Why is this in debate?

6 holes in the backcover...
There are 6 holes total in the back cover of the T-Mo version of the HTS Sensation. I can confirm that the rubber cover I bought at a T-Mo store covers every one of those holes except for the one above the camera lens.
Taking the cover off I can see most of them are just anchor connections for the antenna contacts.

Because US one is 4G, maybe?

It's not really 4G, it's HSPA+ like the EU. Yay marketing
I spoke to HTC support and they clarified that obviously they are there for the antennas and also as air vents. The one above the camera and at the very bottom are mics. 2 for stereo recording.
They did say that all holes should be uncovered. Ironic, since the Body Glove case I bought at TMo covers up 4 of the holes, while many online I've noticed do indeed leave those hole uncovered.
Interesting about the air vents. I also have the Body Glove case as well and all the other cases at T-mobile have all the holes covered except the Mic above the camera.
I believe the case mate case actually covers every hole.

Hello,
I want to buy a sensation case but it does not have the proper hole cutcuts on the back. The only cutouts the case has are the camera and the speaker.
if any of you are using a case with only these 2 cutouts, could you tell me if phone signal, 4g signal, mic, speaker, etc or anything else are affected?
greatly appreciated
i havent had a problem with them after on week of use, but just to be safe, i drilled holes where they should be

thanks for the reply, but if you drilled the holes then your case does have all the cutouts
it does now, but for the first week, i didnt have any issues...
i just did it cuz i was bored, and more as a precaution just in case...
mind you i never used the gps or wifi w/o holes...but i bought the 2 pack, one black (drilled), one opaque white (stock)...if you want, i can check the performance, but as it stands, there was no difference...
ive heard that all cases w/o holes are going to be discontinued, but that may have just been verbal diareah in the sensation thread :/
The only sensible answer is it depends on the case material. For any given case the only way to know is to try it. If it works then fine. If not, then drill holes if they're covered.
HTC says the holes should be uncovered, but none of us know exactly why. For a mic it's pretty obvious. For the others who knows. But drilling is easy and cheap, so for most cases a fix shouldn't be a problem.

Does anyone know what the holes actually do?

I haven't seen a diagram showing the function of each one. Some are mics, either for input or noise cancellation. Others are likely antenna related. It's hard to imagine that HTC would go to the trouble of putting them there if they don't serve a useful purpose. Covering some or all may not cause big problems, but it's not likely to help either.
I have the official Tmobile silicone case and it doesn't have any cutout for the little holes...and it seems to be just fine.

I think I have the same case. Except mine does have one hole cutout above the camera.
Here's my observations that I posted in another thread:
moto211 said:
I've been noticing that most of the cases that are available only have the hole above the camera, even the ones sold by T-Mobile. So, it got me wondering, do the other holes serve any purpose? I took the back cover off and can immediately tell that the hole above the camera serves a purpose since it has a grommeted pass through in the inside housing. So, its good that every case I've seen has that hole cut out. The other four holes have no pass through and appear to only be there as rivet/mount points for the antenna contacts. So, after seeing that, I'm less concerned that even reputable manufacturers like otterbox are not including the other four holes that seemingly serve no active function.

The hole above camera is noise cancelling mic,that is the only important hole,so I had to drill it on my Case Mate Tough.They were the first proper company with hard case for Sensation,so they rushed a little bit with design,others like Otterbox and Seidio are making cases with that hole only.
Guys, EM radiation passes through silicone and plastic. There should be no need for holes on those materials. If you had a case made of metal, then you would need MORE than a hole anyways as EM radiation doesnt radiate in rays...Go into your bathroom and close the door. Plenty of material to be in the way of the EM radiation that is your signal. Still can make calls?
Also, there is no noise cancellation mic. There is no noise cancellation at all on this phone. The second mic is for stereo sound recording. I know alot of you wont agree, but looking up the specs, I found no mention of noise cancellation. (Only stereo sound recording).
If there were noise cancellation, people wouldnt complain about me being in the wind while talking to them. ;-)
Matt
Hmm if i'm not mistaken, two of them are for ventilation, one for noise cancellation mic, and the rest are for the antennas, the one for antennas has no use though, its only there to fasten the connectors.
Hey folks, I was messing with my phone today and inadvertently covered up the left speaker on the bottom which reduced the volume by 90%. I covered the bottom right speaker, no appreciable change.
It looks like the right speaker is full of lint! Any pointers on how to get that out of there? Maybe I should pull the case open rather than jamming needles in there?
Then I was reading this article
http://www.forbes.com/sites/gordonkelly/2014/01/29/nexus-5-review-the-long-term-owners-test/
And it said the Nexus 5 has a mono speaker. Waaaaaiit a second. There are clearly two speaker grills in the bottom. Doesn't that mean stereo sound? I thought I had a lint problem, and now perhaps they're just fake holes?

Nope, just one speaker. The second grill is only for aesthetics. Sucks, I know.
Ghetto!

This thread made me laugh LOL. But on a serious note yes the right grill is a microphone. It's the phones main microphone for say when in a phone call or recording video that's what it uses.
Yes it's funny. There are a million threads about this, yet no one uses search before posting.
I have the white LG G3 and I noticed a speck on the down volume button. It looks like like a tiny pin hole thats in one of the dimples. I was just wondering if there is supposed to be a microphone there or do I just have dirt in the dimple?

Dirt or something in there.. .if its actually a hole you might look into that. the MIC's are at the TOP and BOTTOM of phone. Beside IR BLASTER and the Headphone Jack.

Ok thanks! I know of the microphones at the top and bottom. I guess I need to try to get the dirt out of the dimple.
Hey all. I know the title of this thread is odd, but let me explain. Sadly I dropped my K1 today (never carry a tablet under your arm). Thankfully it was in a case (nothing heavy duty) and didn't fall far, but did land on it's side (left side if you are holding the tablet with the forward facing camera on the top). The screen is fine, but I got worried that something may have happened to the speakers. I downloaded Stereo Test (https://play.google.com/store/apps/details?id=com.jasonfarrell.stereotest&hl=en) to test them and they work, but I noticed something odd. The sound seems to be coming from the speakers on either side of the unit but not the front facing grill. Is this normal?
Yes it is perfectly normal. I have never dropped mine but I have noticed the same thing as well when I am holding the tablet in landscape mode with my hands gripping the sides.
I think the older tablet had holes for the speakers facing towards you when you looked at the tablet but the newer K1 has ports on the ends instead now, so firing side ways?
EDIT ignore me, i can see the holes on the front

Because I'm highly paranoid, can anyone else confirm this? Please?
This is what it looks like under the rubber. Just two holes that the speakers point up to

Can't make out the holes but I do see that there are no speakers underneath the rubber grill. Thanks.
