i hadnt noticed it till you put up this topic! :S
does anyone know what that is? now even i'm curious!lol

now i am curious TOO....

I gees it's the 2nd microphone, which is used for noise canceling.

Don't know what it is but it's not the noise canceling mic. That is located under the screw on the top right (when looking at the back with the battery cover off), there is actually a hole in the battery cover for noise cancellation mic.

Well its right in the middle of the phone, maybe its used during manufacturing?

I always thought it was the motion sensor myself.

Hole for a HW reset ???
Hi all,
While using my new defy+ with a CM10 rom, it was seriously blocked, without any capability to recover it, no USB, no boot, nothing could wake it up again
I decided to disassemble it, and found out that behind this hole was a kind of button
Isn't it a HW reset button ?
this question because once reassembled, my Defy booted again, came up to life again
Any idea, confirmation about this ?
regards and thank's to all of your contributions

Well it might be 18months late but It looks like a tiny external antenna socket or test connection, presumably used for setup and testing by factory/repair depot, judging by this picture:

Its a microphone used to record sounds while taking videos.
Try tapping the hole when recording videos and tapping the hole at the bottom.of the phone and see when you hear the tappjng noise

Did you try tapping it though?
I did try tapping it and it isn't the microphone! with the back cover removed and in record video mode I tapped the middle hole and the hole to the right, clearly the mic is on the right hand side just under the screw (where the hole in the back cover is, oddly enough) It would make no sense to have a mic made of brass and with no hole in the back cover for it to receive sounds.
On the picture above you can even see the mic has a little orange rubber seal around it, it's the square rubber just below the round orange rubber screw hole.

Yes i did try tapping it. I did it long ago to see what it was

hi, this hole is for water detector.
The detector is only a small paper which change color in contact with water.

[SOLVED] Faulty proximity sensor - hardware fix

Caution: not-so-skilled people ask for help to more skilled friends !!!
How a proximity sensor works:
Basically there is a modulated infrared emitter and a correspondent IR receiver. When the modulated light is reaching the receiver, the sensor will become active.
In the mobile phones, the structure is built like in the below drawing. When an object is close enough, the reflected modulated light will be captured by the sensor and it will activate it.

The problem in some phones is that for various reasons the sensor is hyper-sensitive. This should be translated to sensor becoming active when an outside object is even fairly far from the glass surface. But the problem is exactly the glass surface. The sensor is so sensitive it will catch even the refracted light from the glass (remember optics studied in school ?). Some of the light emitted by the emitter will be refracted from the very glass body back to the receiver.
The temporary fix was to "rub" the sensor area while in a call and suddenly the sensor was acting normally. This was caused by the fact that all that reflected light (from the finger) was supersaturating the sensor so, when obstacle was removed, the sensor was no longer hyper-sensitive, at least until the next power-up (next call).
The solution I tested (and apparently it works) is to create some sort of a light attenuator to place in front of the proximity sensor, but under the glass. Well .. the idea came to me while fixing an old remote control .
I'll let the pictures below to speak (thousand words for each ... pretty long story ) ... click on thumbnails for full 1200x800 size.
In case you are applying the mod, please leave a word here, so me (and others) will know the outcome.
I had not even a proximity misfire since I implemented this (roughly 48 ours ago) .
The opened phone (you will fond on the web lots of HOW-TO's about dismantling the defy):
The front case and the board - parts of interest:
Close-up:
Filler material :
"Attenuator" mounted:
View with the phone assembled back:

This seems really promising, I'll give it a try when I can find a suitable translucent material and post the results.

Very cool!
The proximity sensor is actually a part of the motherboard, interesting.
So in my case that my proximity sensor is broken and my LED is permanently on, the only way to fix it would be getting a new motheborad, in another words a new phone. Right?

Weirdest Nexus 7 screen issue

Ok i dont have much light bleed from the edges of the screen, i dont have (so far) screen separation, but on the other side, i have one weird issue with the screen, this issue just started about 4 days after purchase. Now I see some light (you read well) coming in the form of two little filaments, very short about a quarter of an inch, separated by black, now these light filaments are on the left side of the screen about in the middle, But they do not show where the screen is, they are on the black bezel, in vertical fashion, aligned to the screen about halfway from where the screen ends and the side begins, right smack in the middle of the black bezel, i believe that is the right word.
My question is obvious, what could this be??? ps. i know it is light coming from these cracks or whatever they are because when i turn up the brightness these spost appear brighter as well.
I am not sure i have explained the problem too well, taking pictures might not help....this is my issue, im asking you all for you help..
Thanks
Daniel

I've had the same issue. Strange light bleed from underneath the black bezel under the screen:

(This issue isn't visible in this photo. I marked where it is located).
Today i received my Nexus 7 from ASUS Repair Centre in Poland. They replaced the whole screen (LCD+Touch+Silver bezel) due to screen lifting. Now i don't have any lifting and this strange light bleed.

Did you resolve the light issue by sending the tablet to asus for the screen liftin problem? is it fixed now? could the light issue be a sign of a screen lifting problem in progress that is gonna manifest soon? i just dont know wether to think this is a big problem or a small one..

As I wrote earlier:
"Now i don't have any lifting and this strange light bleed." - after screen replacement.

No, I don't think so. That strange light bleeding was "out of the box". My screen started lifting after 1-2 weeks.

[Q] Replacing the notification light diffuser

I repaired my N4 yesterday with a new screen/digitizer/frame and everything seems to be working fine, except that it's missing the light diffuser in front of the notification light and some kind of white rubber thingy. Do you guys know if I can transfer those from the old frame, I couldn't find any resource about this.

of course you can, just use black 3m double sided tape on perimeter of diffuser to be sure it will hold in place .

OK but I don'tknow how to remove the part from the old frame...

it's simple piece of plastic with adhesive to hold it on digitizer glass, just use something like knife to separate from glass ...

I really don't see how it's done though and I'm afraid I'll damage something... If anyone has a video, that would be useful.

You have mounted your screen assembly in phone front frame already and don't have access to back side of glass ? then I think it's too late to ask about light diffuser ...

But I bought the lcd/digitizer/frame pre-assembled...

just remove your old broken lcd from frame and you will see where that white plastic piece must be glued...

I think I will. I just want to be able to put it on the new one without screwing anything up!

problem is that this white plastic must be applied to back side off digitizer glass before mounting glass in the frame ... Now i think only you can do - try to put that white plastic through the hole in frame where notification led is mounted ...

i also forgot to change the diffuser from the old glass. What i used instead was the white piece from te side of the paper foil (in picture), that i cut to desired shape and sticked it in place with 1mm adhesive tape. It looks great, maybe better than the originalone.

Can you tell with more details how you did it? You had to disassembly the screen from the frame? You had to take out and put new adhesive strips on the frame? Thanks in advance.

I used the white strip and cutted small rectangle that fitted. Then i put adhesive tape around and sticked it to place. Thats all

[Q] Nexus 4 Back Cover not fitting in properly

Hey guys
So recently, I removed the back cover of my nexus 4 and did the power button fix, which said to put something like a small piece of paper on top of the lock button, and I did the fix and the button is working perfectly now
But now I have a new problem, after putting back the back cover in, all the sides snap back and taper in like normal, except the bottom side. At the bottom where the microUSB is, there is a line of space where the cover and the chrome meets and it looks horrible. For some reason the bottom isnt snapping in properly, because if i press on top of the cover near the microUSB port then I can feel it snap in, but it will snap out again by itself. Is there some sort of tab or something I need to pull out from the phone so it snaps in properly or something?
Can someone please help me with this? It's really ruining the feel of the phone & making it look old
Here are some photos to give perspective:

Thank You!
EDIT: When I take the screws out and push the bottom sides together the gap closes significantly, but as soon as I screw back the screws in then the gap becomes as big as the photo again...wtf? I think i'll have to use my N4 without the screws

You didn't crossthread the screws, did you?
The screws themselves screw into 2 metal posts that are on the back cover. It seems to me like maybe your screws aren't hitting the holes in those posts, but instead are missing and pushing it them out. Maybe something loose got in your case and is preventing it from closing down tightly, It could be something foreign, or it could be the antenna wire isn't nested between the battery and the frame, or if you completely disassembled the internals, perhaps something isn't snapped down all the way. But it definitely sounds like the screws are missing the holes in the posts, and instead your screws are going inbetween the top of the posts and the back cover, pushing it out and creating that gap.
