It's normal. That's just a part of the camera module moving slightly.

It's the auto focus mechanism and that's normal.
OIS lens' have elements in them that are free moving when the voice coils are not energized. So when you shake it the rattle noise you hear is the element moving and reaching its mechanical limits. This is perfectly normal. When the camera is engaged, the voice coils are biased with a small current that keeps the element very steady. This current is modulated according to the movement to counter handheld shake. It allows longer shutter speeds and lower iso values to improve image quality at lower light levels.
OIS on cameras and lenses have settings to turn it OFF so if the camera is on a tripod focused on still object there won't be interference. I wish there was a toggle to turn it off on phone cameras too because loud music can cause the servo to go into full hysteresis (oscillation) making the video almost jelly like when a kickdrum or synthbass hits hard, etc.
Open your camera app and shake the device lightly. You'll notice OIS kicking in
That's the first thing I noticed, once I pulled my S20 Ultra out of the box
See here. IMHO the $1,700 phone (16G,256G) should have this element "parked" when not in use .

Is it normal for the TP2 picture to stutter when trying to take a picture. If there is perfect lighting in the picture there is no stuttering in the picture, but if there is a light source or if it goes from the dark to a light area it stutters badly as it attempts to balance light levels and focus.
Does anyone else have this issue or is this normal?
When you say "stutter" I suppose you mean that your pics come out blurry due to your device shaking in your hands?
This is normal in low light conditions. Since there's not enough light, the camera compensates by slowing the shutter speed to allow more light to pass through the lens. The bad side to this is the slow shutter speed will also exaggerate any camera movement and this translates to blurry photos unless your device is fixed on a stationary object (and your subject is not moving).
yes! that is exactly what I am seeing. Yeah, i did not know that was normal. the screen refresh was so choppy it is hard to take a clear picture in low light. This is my first nice phone ive had and i am not used to all the features. Thanks for explaining that to me, I appriciate it!
You're very welcome, man. Just so you know, this isn't specific to our TP2. It applies for all cameras. Those with a flash would help a bit, but not much if it is really dark.
If you try to take a picture with any camera outdoors at night without a tripod and flash, it'll come out terrible.
I just laughed when I read the TP2 camera was 3.2 with no flash.
I will never use the camera because the pictures will come out looking like crap 90% of the time.
The camera for me is honestly useless. But oh well, the rest of the phone makes up for it.
camera works good with barcorama app. takes decent pics in well lit areas
Weird sound when hitting the back, specifically around the camera this sound is generated, someone else happens to this
Yes, the camera has optical image stabilisation (OIS). This allows camera to physically move. When you tap the phone you will hear the camera moving. This is normal.

No, this phone is only have EIS. OIS is too expensive to be implemented into this phone.
And yes, I also experience this weird noise when there's a bump on the top back cover. Don't know what cause this though
Perhaps the vibration motor? I have the same sound.

Oh ok. I saw a teardown video and the camera did move in it's socket when it was touched. So I still think it's the camera shaking that is making that noise.
All previous phones that i've owned had OIS, and they made the exact same faint 'tick' sound near the camera when phone was bumped.
But i guess it could also be the vibration motor, since it's close by the cameras.
It can't be OIS, can it? I don't notice any stabilization in photo mode and in video mode the stabilization feels like that of EIS
Is anyone having camera issues?
For whatever reason, when I try to take a photo of my dog, the face looks smeared. Roughly 80-90% of the time. While on my iphone it looks great...I'm kinda bummed out about this and wondering if this is either an issue with my unit, or if this is a common thing with Samsung.
Also, just for some more info, I've tried turning on/off hdr, scene optimizer, and whenever I am ready to take a picture, it looks stunning. Then I hit the shutter button, and it turns out like poop. Barely half the quality of what it looked like before I hit the shutter button.
Here are two pics to compare so you can see what I mean. If anyone has any info regarding this please let me know, thanks.

I have always seen this happen on Samsung phones (S8, S9, and S10) when taking pictures in certain lighting situations. Especially inside when taking pictures of a rug or anything slightly fluffy. It is as if it is trying to apply the beauty mode to everything.
Try to get the AF to lock on to the animal's eyes.
A good pro cam can most times; it's a small but high contrast target.
-If you don't grab the eye(s) you lose the shot-
I haven't done any research how this cam's AF works; normally you would point focus AF although it may still target the hair as it's a high contrast target too.
There are a lot of high contrast targets in this shot, the dog's nose, that chair, the dog's hair and the floor boards. Try to limit potential AF targets by keeping the composure simpler and less cluttered with high contrast targets if you intend on capturing a face with the eyes in focus.
Getting closer to the subject makes an AF lock on the eye more likely. Try punching up the yellow focus/tracking square.
Worse with this cam's large aperture it makes for a shallow DOF which means a spot on focus is needed. The aperture setting is fixed so you can't stop it down to something reasonable like f/5.6 however this cam is sharpest at it's fixed aperture. Backing up therefore may help get more of the subject in focus. You need to learn to see through the camera's eye, as it sees rather than your eyes.
It is much more limited than the superb human visual system...
Manual focus is sometimes the only sure fire way to do it. In the pro mode it does have manual focus but lacks the smooth ring control of a good piece of glass found on stand alone cam systems.
A trade off... it's only a smartphone.
First, nice looking dog.
A couple of questions.
What were the lighting conditions?
Was your dog moving?

Samsung applies way to much noise reduction destroying the details of a photo. This is why it appears like that. Also, there's nasty shutter lag with the stock cam...so you press the shutter to take the pic but it doesn't happen right away simply because hdr is always on no matter if you have the switch off or not. Basically Samsung have rendered there stock camera useless. Get the latest GCam port from arnova....all problems solved.
Hi! When I'm switching between cameras modes I can hear and feel a little noise and vibration, Anyone knows if are they part of the UI or the cameras have some moving parts?
Thanks!
Optical image stabilization. I believe one or two of it's rear cams have this.
Yup, it is indeed the image of stabilizer that is shaking around
Wow I didn't expect this sound from the stabilizer, at least now I know is not a problem
Thanks!
Also auto focus moves the lens in and out, so its a combination of both systems de-energising and the lens bouncing back to it's free floating position.
It's the OIS, every OIS rattles, the bigger the sensor/lens, the louder the noise. Watch this video for more information. Pixel 6 Pros periscope lens has a relatively "loud" rattle noise, as has the S21 Ultra as another example.
You can also try it out with previous phones: Shake it harder than you normally would, and you will be able to hear the same noise, just a tad more quiet.

What's funny is that when power is applied to the OIS, such as when you open the camera app the OIS doesn't rattle as it moves to stabilise your picture. On my S21U, the OIS always was always powered so it wouldn't rattle even when the cam was off(Samsung probably did this as people were returning the phone thinking it was faulty) but this caused a wakelock and battery drain and people were complaining. On one of the last updates I had before I sold the phone, they removed this so the OIS started to rattle again when the cam wasn't being used.
I've have the phone since October.
Mine made no noise from launch until today. I do not think it's to be making a clunky rattle. Not heard anything about this but found a few threads where Google just says it's normal because the camera has moving parts. I have had many cameras with moving parts that did not start to rattle after 5 or 6 months.
Just picking it up made the noise and just turning it over as well.
Anyone get a fix or replacement?
Mine sounds like it has a few marbles in it when I shake it. Ditto for the S22 ultra but not as noticeable. When the OIS isn't active, the lens can move. To keep it parked would require a constant current draw.

They ALL make the ratting noise when you shake them because of the stabilizer in the camera. It's totally normal. Yours did it from the day you bought it but you probably haven't noticed until now.
It is the lens elements in the periscope assembly so it is a bit louder than normal but all OIS lenses rattle if you shake them hard enough.
Samsung even have a page dedicated to it. https://www.samsung.com/sg/support/...of-the-device-when-shaking-your-galaxy-phone/

This.
Now, some OIS are prone to rattle more, usually on bigger sensors/especially with a periscope lenns.
You can also shake any of your older phones (Iphones, Pixels, Samsungs, whatever). They will ALL make a rattling noise (as long as they have an OIS), if you shake them and hold it close to your ears. Most "older" phones with smaller sensors/OIS are just much more quiet in that regard.
It's absolutely normal for your Pixel (6) to have a rattling sound when you shake the phone.
Mind also, that this is a potential weak point. If you rattle the phone too hard for too long, it's possible for the OIS to break. Now that will usually never happen in a normal usecase, but I've seen several reports of motorbike owners over the years and their OIS problems, since the constant bumping (they used their phones for navigation) with high speed (100 km/h +), thundering over potholes and the likes, permanently damaged the OIS. It is, after all, a moving part. And all moving parts can break.
Now, I do not know how "hard" your rattle is. Your text said that this "developed" over the months. That should NOT happen. So they question is: Did the rattle really increase, or did you just become aware of it?
If it "changed" or "increased" it is indeed possible that something changed/broke (you can test the OIS functioning by making a simple video and seeing if the stabilization kicks in).
You can try to find out if it's the "normal" OIS rattle sound by going into the camera and forcing the different lenses (zoom in or out), whilst slightly shaking the phone. If the zoom kicks in (periscope lens) the "heavy" rattle should effectively disappear. If that is not the case, it's rather likely that something broke at your end.
Thing is the rattle in mine goes away when i don't think about it and it only comes back when people remind me it rattles.
Got my pixel 6 pro on 29th march I just shook it by ear and can hear a rattle

If the camera app is open the rattle goes away as the bias current applied to the coil is fighting movement.
Interesting tidbit when using a video camera with stabilized lens on a moving ship we have to disable stability (when camera is on tripod) or the rocking of the ship causes the stabilizer to hunt and the image itself moves slightly which looks very similar to a motion picture scene on a ship where it is intentional to give the viewer the feeling of the ship rocking. This with professional gear with large lenses, not sure if it would affect phone cams though.
Put it on 4x zoom and you wont hear the rattle.
It's normal
