Houseing noise? - Xiaomi Mi A1 Questions & Answers

I noticed some noise, not software relating, whenever I leave it on table, bed or something else, ( I do not throw it) I noticed a slightly noise coming from camera and sensor area. I thought that the side volume button, which is a bit loose, does the noise, but I pressed both of them an the noise is there.
If I tap slightly on camera/sensor corner I can hear some kind of like something is loose inside of it.
Has anyone noticed? Or has the same problem?
Thank you.

Probably the phone vibration motor. I noticed it too, mainly when I put my phone down on hard surface. It was more or less present on my previous phones too, so I guess it's normal.

Thanks for reply. I thought that in might comes from the lens.

You are right, noise comes from around the lenses. I've just checked the tear down photos and vibration motor is located near the usb port on the opposite side. So...I don't know what could be the reason

The sound is due to the Camera Lens Barrel required to operate the Auto Focus function. So basically, there are moving parts in the lenses, which are adjusting focus depending on how far the object is from your phone so the pictures are sharp.
Camera module is fitted with a “Stopper” to limit the Lens Unit movement within the space for the Camera module. When the Lens and Stopper touch, when shaking the phone, a slight noise may occur.
That means it's perfectly normal

I was not wrong thinking about Camera Lens.
Thanks for making clear and detailed explication.

Xperia X1-somethink grumble inside??

Hi i have question.In me Sony Ericsson xperia X1 from first day somethink rattling in side.Exactly in high side ceel phone (around picture camera lens)If i only litle shake with this cell phone you can easy hear this ratttling.You have this problem with your Xperia???i makc phone call to sony ericsson technic today and he said.This rattling is regular.if you have any experience let me now please?Thank you.
Dont worry, it is for all the X1.
There was a thread here for the same "isue"
it's one of the buttons...
Rattling
No it not one of the buttons im sure about this this rattling is inside the cell phone.
it's the lens
Hi,
that noise you hear is the lens in a certain focus position.
I found, that in a certain position the lens it moves and makes noise.
After using a program called QuickMark, my lens keeps moving and to fix it I've to open the camera and press the camera button till it moves the lens for changing the focus.
After that, no more noise.
There are actually two different sources for the rattling noise.
If you shake you your phone up/down in it's horizontal position you will hear the lens. If you shake it up/down in it's vertical position, you will hear the supporting wheels for the sliding mechanism.
I dont think its the support wheels for the sliding mechanism, i beleive its the touch D pad that makes the rattling noise
Try holding the touch D pad and shaking it - the rattling noise will be significantly lower (considering the camera rattling)

I thought that too at first, but by holding the touch pad you also give the screen part of the phone a press enough to letting the wheels rest on the keyboard part, thus lowering the noise. When not pressing the two parts together, the wheels have no contact to the keyboard part, which give them free movement to rattle.
really?, I'm pretty sure its the Dpad, try wedging like a bit of paper between the touchpad and Dpad keys [thick enough to stop the touchpad from moving] then try shaking - rattling solved for me . . .

Nah, not for me.
Conclusion: we have three rattling noises depending on the individual phone. Mine is the supporting wheels and the camera lens, not the touchpad. Yours the opposite.
Glad I'm not having all three of them. On the other hand, it really doesn't bother me, just curious where the noise originates from.
i just notice that mine was doing the same thing 2day. actually i just heard it.
for it its the wheel. cuz at first i dunno wat it is. but then i got a pin and held the wheel down and then shook it again but then no rattle occur.
is this normal?????
i kinda want to get it fix since it did cost alot. and i only had this phone for like 20 days...
it is the sliding mechanism, try pressing the 2 parts of your x together (closing the gap between the screen and the KB) then shake it again, you will find it's gone.
check here for more info

well by pressing down on it it does stop for the time that im holding it down.
but is there a way to fully solve this loose wheel on the sliding mechanism?
i don't think so,
soon you will forget it's there, don't worry
lols yea...i hope so...i just spend soo much on it...i dun want it to just "fall apart" lols
but thanks for the info
It's the camerabutton. Touch it..it's a little loose.
Lol
Who actually shook their phone hard enough to hear this? I just shook mine and I can hear what is said to be te lens but is quite possibly the d-pad, and what is certainly the tiny rattle of the little slider wheels.
Barely noticable, especially since I don't go around shaking my Xperia.

loose part sound when shaking topaz

not sure if this is normal, just noticed that when I shake my topaz I'll hear a small ticking sound, like some part fell loose inside.
Is this normal or that's part of the the G-sensor thing?
anyone else having the same problem?
I've got the same thing going on. It might be normal, but i have no idea whats making the noise.
I think that is just the vibrate motor, since my Pure does the same thing.
I just shook mine fairly vigorously then, and no sound whatsoever.
when i shake mine i can only hear low ticking sound that cames from power button.
The power button is a little loose and it can be shaked by front to back direction with finger as well.
but when i shake d2 with holding power button, there is no sound.
Stop shaking it!
Hi
Not a sound from mine, no matter how vigorously I shake it.
I would stop shaking it if I were you - if it's working, don't tempt fate!
Cheers!

thanks, yep I think it's the power button that's making the noise. no more sound if I put finger on top of it.
gravity sensors in most devices usually have a little rattle to them, it's completely normal.
The only normal sound the topaz makes while being shaked is the lens of the autofocus camera.
There`s been a topic about the exact same thing already.
Yes it is the lens. Take a picture and listen very carfully: when the picture is taken you will here a soft clicking/ticking sound (same sound it makes when shaking the phone).
the clicking he means/meant is the power button. most d2 users will know this.
Whatever it is that's making the sound, I agree it's normal. I have a Pure and a Topaz and they both do the exact same thing. I can get it to sound by lightly tapping on the back cover up by the camera lens.

Problemes on LG F320L help

Hello
I just get a LG G2 F320L, but for three days I noticed a few things that do not work:
the camera or the rear camera; his makes me fuzzy images, even when I want to film a video, the video shakes, even if I want to take a picture, the rear camera shakes alone, I tried to lower ISO, quality, mode, but not many changes, when I'm close to the subject or the object that I want to photograph, his pass! but when he is away, it is a problem (if the images are attached)
Here are some pictures when I take a picture of something that is near

when I take a picture that is a bit far, I notice that tremble as if the lens

brief when I want to shoot a picture normally I find great difficulty, although the green rectangles appear, the picture is blurred, as if the lens vibrates
Up plz

Looks like a hardware defect or Parkinson's. Maybe you could try taking a picture using a stand/table and place the phone carefully against something like a book to take a perfectly still picture?
I tried what you said but the camera shakes alone,

I bought f320k model from aliexpres and I have the same problem. I had before d802 and camera has been much much better.
I had the fuzzy and shaked pictures problem too, but I figured that the problem is the magnet of the speaker... The camera has its own magnets to control the lens, but the speaker magnet is very close, so this "interference" causes that the camera dont focuses properly... My fix was put a layer between the camera module and the speaker, and now the camera works like new!

Camera/video image seems to lag when phone is moved...

[I searched for this on the forums -- apologies if it's already been answered.]
I'm photographing/videoing through a kaleidoscope. Beautiful results with fixed shooting, but a problem when moving the phone. I made a small rig for the phone and a prismatic kaleidoscope (one with a glass element at the end), so that it's locked in place directly in front of the rear lens, and is completely rigid with respect to the phone -- no relative movement. (In other words, the phone and scope are part of a fixed unit.) THEN... when I hold the rig, and point it around the room, the image seems to lag slightly behind the movement, almost as if there's an inertia in the filming. (For example: start off motionless -- wonderful picture. Then move the camera upwards -- the image shifts up, but when I stop moving the phone, the image then continues moving slightly. It's always in the same direction as the original direction of movement.
I notice this with the camera mode too: hold it still in your hands, and then move it smoothly upwards. When you stop moving, the image keeps moving a little longer.
Is this some kind of damping on the camera, to stop jerky movements? Is there a way to turn it off? It makes locked-off filming of the kaleidoscope image almost impossible (or at least, it looks pretty poor, as though it were hand-held).
If anyone has any ideas / solutions, I'd be grateful; in every other respect the filming on the camera is superb.

Update -- a weird parallax effect (without the parallax)!
Hi --
Looking into this in more detail... here's an experiment to try. And if you can explain why it happens, I'll be impressed.
Hold the phone up, in camera mode, pointing at a distant wall, say, and hold a pencil to one side of the phone so that it partly sticks into the shot. (Angle the pencil so that it's pointing away from you, then try to focus on its tip.) With grid lines turned on, and keeping the pencil as still as possible, relative to the phone, move the phone gently from side to side.
The pencil MOVES relative to the gridlines, swaying back and forth (and up and down too if you move vertically), even though you aren't changing the position of the pencil relative to the camera by one millimetre!!!
What is going on? Why is the camera software (it has to be in software) doing this?
(I have a video of this to which I can post a link, if people don't believe me!)
I doubt there's a solution to the effect, but I'm intrigued to know why it happens (and immensely frustrated).
AND I've just discovered that it doesn't happen on a colleague's S5 !! did Samsung change the way in which the software works?
Peter
i believe this is the OIS feature of the camera. I don't know if it can be disabled though

Rear Camera Clicking Noise

I am experiencing clicking noise when I shift between front and rear camera, changing between modes for rear camera. It's a fairly loud noise, at least the loudest I have heard for all the smartphones I have owned since a decade ago.
This is weird because the noise seem to start on my 2nd day of owning the phone. Don't think I notice it yesterday.
Any of you experiencing the same?
THis is completely normal. It's just the aperture opening and closing quickly.
If you look closely at the middle camera while switching between front and rear camera (just swipe up on the screen while looking at the rear camera), you'll see the aperture quickly close then open again. That's the sound you're hearing. Nothing to be worried about.

If camera aperture closes n open hundreds of times per day will it cause physical damage? As it has physical components?
Coz i use snapchat a lot
And whenever i open snapchat it ll open close the aperture shutter.
Yes, the aperture operating sound is unusually loud.
