Can you please quickly look at the top ear piece and tell me if you can see some flat metal thing partially under the speaker grill mesh? is that normal?
thanks

well I haven't ripped one if these apart yet but my guess is that they had to suspend the speakers in their own little chamber in order for the acoustics to work with the waterproofing. I think that metal thing is the speaker itself.
I have gone through 4 Z3s for one reason or another and all had the same appearing top speakers so I'm guessing it's normal.
I can see the same with mine so I'm guessing it is normal for these devices

I have replaced 3 Z3s (Cosmetic defects) on my 4th, I can say its normal it's on every one I have seen.
Same here on my Z3.

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.
http://www.slashgear.com/t-mobile-sensation-4g-review-03156640/
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.

So I've been trying to figure out what all the holes on the back are for. I'm sure one is a Mic but what about the rest? Thanks

The one at the very bottom is a mic hole The 2 towards the bottom and the 3 one the top are rivet holes for the antenna connections holes but the one on the very top also acts as a hole for the stereo mic and noise cancellation. .

The 2 holes towards the bottom of the case seem unnecessary, leading me to believe that they could potentially be a water detection system. In the event that the phone gets dropped in water, these two holes would be some of the first areas to get wet, it would be pretty easy to detect a short between the two pins and disable the electronics inside if such a situation is detected, possibly saving your device from permanent damage.
Now I haven't tested this theory, mainly because I wouldn't want the device to log such a situation if that is how it works, but it would be relatively simple to test if anyone is willing to give it a go .
Most holes on back are where the copper connectors are under the cover..
Breathing holes I assume..
this topic has been covered a plethora of times!

Exactly...
I contacted HTC the day I got this phone....
Straight from the horses mouth....they are antenna rivets AND vent holes.
why is that ??? why holes ?? i havnt seen this sh*t on any other phone!!!!
thats ugly

And this is why I suggested that perhaps they may be specifically designed for water detection, it would be trivial to have the hardware shut itself off if there is no resistance between the two leads to prevent permanent water damage... Just my two cents.
so, couldn't someone put a paper clip or needle in there whilst the cover is on the phone to see if it turns it off?
Hi, I've been lurking the dev section for about six months and have a rooted ds which has sampled many of the great roms available but it has developed an issue, when I make or receive a call the buzzing/vibration makes it difficult to hear the other person. When I look at the grill covering the ear speaker it looks like I can see debris behind it glistening which makes me think metal filings? This would be consistant with me working with metal in my job and accumulating filings/flakes in my pockets. Any ideas how I can get them out guys?
Thanks.

The only thing i can think of without dismantling the phone, is to turn it off, take the battery out, then pass a stronger magnet than the one in the speaker, over the grill. It may take some time but maybe you could coax them out that way. Unless the filings are non ferrous of course. In which case it may need taking apart.

I may have to give that a try, would the magnet not damage the phone? What I don't understand is how they got in there as there are two that can be seen that are about 2-3 mm in size.

I can't guarantee what effect the magnet would have, which is why I would turn phone off and remove battery first. The speaker itself has a magnet in as all speakers do, so in theory there should be nothing in that area of the phone that is susceptible to magetic ill effects.
If there are pieces in there too large to come back through the grill then the magnet is not going to be any good. I'd guess they've found their way in through the headphone socket then.
In which case I'd recommend taking it to a phone shop to be dismantled and cleaned out, else you'll be limited to using a hands-free kit or the speaker phone to taking calls. Plus the last thing you want are metal filings rattling around a circuit board! I know it's closing the gate after the horse has bolted, but if you get it cleaned out, I'd recommend getting this case...
http://www.amazon.co.uk/Otterbox-Commuter-Case-HTC-Desire/dp/B0043QE6SE
It offers fantastic protection, and features rubber plugs to cover the USB and headphone sockets which will prevent the phone getting full of bits from your pocket again.
Ok, thanks for the advice

I got some bits of dust in my grille. Any good way of getting then out beside air duster?
I just blow on it till they get out.

I wouldn't blow on it, or into it. It'll just force the crud up against the speaker. I had to replace the ear speaker on my old Rezound because of this.
I have a somewhat more critical situation than pocket lint or fleece fuzz, however. I run a machine shop, and there's constantly metal chips, shavings and filings that get EVERYWHERE. I put my phone to my ear the other day, and scratched my ear because there was a steel chip poking out of one of the holes. I found a solution, though... just dragging a pair of steel tweezers past the holes causes it to be magnetized by the speaker, and it draws any metal out of the holes. I've only had the M8 for two weeks, and I couldn't believe how much crud had already found its way into those tiny holes. And, I'm really careful with my phone!
Try a tooth brush my gf used it on her one x+ and it worked like a charm.
Man, I'd just vacuum that sh*t out lol! If you have a small computer vacuum, that would work perfect.
Cover one end of the speaker grill (to the left of the specks) and blow air/use an airduster on the right side of the specks, and the air trapped on top of the speaker (but still under the grill) should force the specks out of your grill.
-OR-
Play some high volume bass-filled music with your phone upside down but raised from whatever surface you have it on.
Both of these have worked for me, do hopefully one with be of help to you.

Since around a week ago, my z3 got water contact. It was not submerged but it was just a water splash. After that bottom speaker sound very quiet. When i do service test the bottom speaker is very quiet. Also loudspeaker calls are very quiet since it only used the bottom speaker for that. I tried everything from putting silica gel on top of the speaker, putting it on rice to cleaning with alcohol. Do anyone experiencing the same? Should i be worried now or there's a chance it would go away. I can't have warranty since this unit was a grey unit

Then better get it replaced my best suggestion, u can give as argument that water came inside the devices speakers and it don't go something like that, at least they can repair but give good arguments
