Small rattle noise near the camera

Hi guys... I receive my phone today just like many of you here and noticed if you tap your finger on the back and side of the camera it has a rattling noise like something is loose... I think this is the vibrator, but just wanted to find out if anyone else had experienced it as well and if this is normal?
Ok guys.. after a lot of searching around mainly on the Nexus One forums I can confirm that its normal for your phone to have a little rattle... its the autofocus on the camera..
well I have the same rattling noise... at the beginning I didn't mind it as it was only noticeable when I was tapping the back of the phone.
However in the past 2 weeks I noticed that if I set the in call volume to one of the last loudest 3 levels, I can't even understand the other person, because of that rattling noise...
Anybody experiencing the same thing?

Slight rattle from the phone

If I tap just below the camera on the back cover I can hear a slight rattle, almost like a loose component. You can slightly hear it if you shake the phone but it becomes louder when tapping it.
Does anyone else have this or is it just me?

What you hear is probably the camera lens - the bit that moves inside to focus the subject. Its like it on all phones with this type of lens (had it on HD and HD2).
Thanks. Just wanted to make sure it was meant to be like that and the it isnt faulty.
Its problably the volume rocker, its a bit loose fit. It is the rattle with me..

Build quality?

When I tap my phone on back cover near the camera there is a distinct rattling sound. It's as if there is something loose inside the phone.
Has anyone else noticed this?
Nothing here, for me build quality is superb!
mines nearer to lower left section of back cover behind the home key but only just a minor creak.. to be expected with a plastic construction I guess (waiting for HTC to release a Legend type unibody on Desire)...

Same problem here. I'm going crazy from this sound. It seems that it is something in camera construction (maybe autofocus?) because when I take photos I get the same sound.

It's your camera.
A lot of phones that doesn't have fixed focus will have this issue. It's due to the lence moving inside its housing, creating that rattling sound.
My previous 3gs had it, my desire has it now. Nothing to worry about, but really annoying
-e
Same here. Unfortunately it seems that this is a problem with HTC Desire.
No, its a problem with the cameras HTC uses. My Hero had the same rattle. so did the phone a friend uses. Other brands have the rattle as well.
It's just part of the camera and autofocus. wouldn't exactly call it bad build quality as well...

Thanks for the replies guys.
I had better stop tapping it if it's the camera! LOL
Wasn't sure if I should request exchanget but if they are all the same then no point.
Presumably it's the rattle that lets the camera zoom optically?
My N82 has this too. I'm pretty sure most autofocus camera phones will have this. I certainly don't think its a problem or a build quality issue. Does anyone NOT have that rattle when they sahke there phone upside down?
I have the rattle aswell. Oddly enough I have an LG Viewty with auto and manual focus and it doesn't have the same rattle. My N95 8GB didn't have the rattle either. My digital camera doesn't rattle either when I tap the lense. I'm guessing that it's just because the lense isn't that great.
Some devices are known to have this problem. Is is coming from the camera and is perfectly normal.
No rattles here, however frame of my desire is a bit... bent. You know, that brown part?
I pushed in so it's kinda ok now, but from some angles I can see light leaking out.
Some with trackball, the ball is a bit pushed to the right side, so light leaks out on the left side.
Kinda bummed for that, I mean this is after all quite expensive piece of technology...
EDIT: after some knocking around, there's that rattle, ARGHHHHH
It's the autofocus mech in the camera.

Cause of haptic feedback rattle found

In my particular case, the camera is the culprit. It seems that the black piece inside the metal square chassis rattles when you tap it. When the vibration motor is active, it rattles the camera inside. Just sharing since it seems this issue has popped up a couple times.
Only solution I can think is to take out the black camera piece from the chassis and maybe stuff it a little tighter or order a new replacement, but the camera could be made that way. I'll take it apart again later today to see if there is some space for small paper or something to keep it still.
I've been getting this rattle for awhile now and was wondering what it was. Between the touch screen and bootloop, this is the third strike.
I also have a sound from the sound vibration motor, but its not so much a rattle sound, more of a beeping/squealing sound. Is this normal? Its not very loud but it annoys me when typing in a quiet room. Remember I had the exact same sound on my last LG phone so maybe its an engineering thing or the brand of vibration motor.

I noticed this on the forums too. I listened for this but couldn't find it. If I put my ear really close to the motor I heard a small whine, but it seemed like it was something else rather than the motor because it was constant. I will say the rattle could sound higher pitched to others depending on movement. My sound is a small rattle but I could see how maybe it could vary to a squeaking or squealing noise to some.

This is how mine sounds, mic is right next to the phone so its louder than during normal use. You have this to?

The camera has Optical Image Stabilization. Packing the gaps will stop this working. The rattling is just the camera moving around.

Did you listen to the sound in my video? You have that to? Its mostly when using haptic feedback on home and back buttons and the third button down at the bottom

Does your ear speaker make a noise when you have the rear camera enabled?

So I have sensitive hearing and catch this sort of stuff but wondering if it's normal or some odd defect, despite everything seems to work.
If I open the camera app I hear faint white noise and it seems to come from the ear piece if I put it up to my ear. Almost like if you're on a call but no one is talking and you hear the silent ambient noise.
My only guess is either they seem to share some common power and the speaker is powered with the camera or something is funky on mine.
I did get on a call and open the camera app (it does it at that point still too) just to make sure both worked at same time.
It's not super loud/obvious but in a dead silent room is where I caught it and now know it exist ha.
anyway just wanted to see if anyone else could test that.
Put phone to ear like on a call, not you hear nothing.
Open camera app and put to ear and see if any difference.
Mine has the same hissing sound. But I had to put my ear close to the speaker to be able to hear it. I really don't care since I don't take pictures with my phone near my ear

Yea I think I can live with it just wanted to make sure I wasn't some unique snowflake with this odd issue that later would turn worse because it was a defect.
I guess it's possible to still be one but not being the only one with it eases concerns hah.
Thanks for checking!
Yeah, I hear it too. Must be the OIS ? Probably the small electromagnets in there causing some inteference with the earpiece.
I have that problem too. when i open camera app or switching mode(auto to pro), it make noise and I notice that its camera aperture change then make the noise.
anyone know that problem? it is hardware or software issue.
It´s not a fault - it´s by "design" (why I don´t know thou). It has been like this for many generations of Samsung phones now (atleast S6, S7, S8 & S9).
