Whenever I am recording video it seems to be constantly going in and out of focus. Any idea what I'm doing wrong?
Care to expand so we can help?

You couldn't ask both your questions in one thread? Post some examples.
I'm not sure what else to say besides it oscillates constantly, meaning fractions of a second.

I don't think they should be in the same thread because they are different issues. Perhaps they are related, but then it would be do to a hardware issue.
What's the preferred means of posting examples?
If your having problems with both stills and videos, then it is likely related. You can attach jpg files to your post. You can upload vids to YouTube and post the links here.
Here are a few example shots.
The 1st shot is with the camera settings at default. The 2nd shot has anti-shake on. The 3rd shot has auto-contrast enabled.
As you can see they are all grainy and blurry even though I'm taking an image of something that is not moving.
The light produced from an overhead halogen. However, the pictures turn out similar under standard incandescent, fluorescent, or any other non-natural lighting. Also I tried out several other settings without any improvement (e.g. setting white balance to incandescent, setting the scene to party indoor, using macro focus instead of auto, etc.).
That's sensor grain. It happens when there is insufficient light as the sensor has to work harder to expose the scene and it heats up. Also, since the scene is so dim the camera is using a slower shutter speed, which results in some camera shake that causes a less sharp photo. Can you take a pic with the flash on? Also, if you are expecting Canon-level photography from this (or any cell phone camera) expect to be disappointed more often than not.

Cool, thanks so far. I will try it with the flash on. I have taken pictures in a lot of indoor light and if anything is moving the whole image is blurry. Sometimes it looks like the air is shimmering.
Perhaps what I need to do is to use something other than auto ISO?

Nope, just like Miami_Son said, auto flash will make the difference. That or bright enough lighting. Try it during the day time.

Like I said, in low light the camera will pick a slower shutter speed, which causes camera shake and blur of anything moving. What seems well lit to the eye is different for a camera sensor. Either use flash or turn on more lights. You can try turning up the ISO, but that can also increase grain.
Record video in 720p and the autofocus issues should go away.
Ok, it seems like every picture taken under the conditions mentioned above(sorry forgot to write them: natural light, inside my room, pretty much a well lit room, besides the fact i didn't turn on the lights) and everything else set on auto, have the same result. I get either a blurry shot, without the antishake option and a noisy one, when having antishake on.
Also i would like to mention, that this particular behaviour happens in a rather well lit environment. The only time i get acceptable results is when i go out and shoot in the natural sunlight.
Is this normal?
You didn't list any conditions above.
Let me just add some examples, maybe you will understand what i'm talking about a little bit better
1. camera ics+
2. camera zoom fx
3. stock samsung camera
4. lg camera pro
Your iso settings are wrong. Change it to auto.

As i already mentioned, my iso settings are set to auto. Any ideas?
i m having same issues, suddenly, the in door shots are coming with horrible noise
Sent from my GT-I9300 using xda premium
it's normal for a cell phone camera - or any type of small sensor camera, actually
Well then, why other camera apps shoot a little bit better? My old Samsung Omnia was a better shooter in this regard. Also, could you provide some photos too?
Scratch.
You edited your post.

I did, but my iso is always on auto nevertheless
I would try three things:
- Set ISO manually. I don't have an S3, but with my S2 I get the best results by setting ISO manually.
- Turn antishake off. In general, electronic stabilization adds noise (unlike mechanical/optical stabilization which does not add noise).
- Try to hold the phone a still as possible while taking the picture.
That said, keep in mind that any small sensor camera like what you have in any phone is not going to perform well without good lighting. However the S3 should be one of the best of the phone cameras.
yes u r right that while using antishake option it produces noise thats y its off by default!! and u r wrong that it is blurry bcoz if antishake is off my gs3 takes noise free perfect pictures its has a gud BSI sensor (Cmos) try not to shake ur hands while taking pic.!

my first gs3 phone's pictures were immaculate in doors and out, but i had overheating issues so i got a replacement...this new phones camera does this...too much noise, didn't have that with the first phone the replacement phones case came damaged so i'm hoping to exchange it once more...hopefully the next phone won't have this camera problem....
I have the same issue, I've been comparing the pics with my S2 and results are really bad indoor, except with flash. much better than S2 with flash! im really puzzled
I had posted here my cam firmware version, I'm wondering if it's the camera app or else

okay....i am not sure whether you guys have knowledge about photography
exposure is measured by 3 component
ISO, shutter speed, and aperture
as long you have sufficient light (outdoor during daylight), lowest ISO will be used by the camera and it results no noise
ISO --- sensitivity to light
you will have noise or sometimes blur in door or low light situation...
that is because aperture of camera has opened wide then it results other two components compensate to maintain proper exposure
that will increase higher ISO (more noise) and shutter speed is slower to get more light ...
hope this explains why

I dont think you understand that I have S3 and S2 with me and test them under the exactly same conditions and results are very different from all the tests of S3 on the web which clearly show that S3 takes better pics.
hm....it's hard to explain...unless you have DSLR and know how to do manual setting...
besides i am referring this to OP thread,NoOneCanHelpMe why there is camera blur and noise
So ive been using my xperia s for 4 months now and ive noticed that the camera capabilities is really close to perfect when taking pictures under very good lighting conditions but under low light, the exmor r is really bad.. I always end up getting either noisy, grainy, and blurry pictures.
whenever i switch to night mode and take a picture on low lighting environment, everytime the camera locks on ( green square thing) i see a very sharp and perfect pic. But as i snap it, the picture that comes out is not even half as good. And whats worst is that 4 out 5 shots are blurry. i dont know if this is a software issue or hardware. Im currently on ics. 452 firmware.
You can clearly see a perfect picture when you half press using night mode. But as you press it all the way, its a whole different pic. Is this a bug? Also, im really struggling at times taking still shots. The problem doesnt occur under good lighting conditions thats why im suspecting its probably a software bug. Anybody experiencing the same?
Search the forums, its a well known fault. Doesn't seem to be a fix that I've seen unfortunately.
Sent from my HP Touchpad via xda app.
Yea, I have the same problem, try using 3rd party apps, like FV-5 Camera, and try using as low ISO setting as possible to get perfetct pictures at night, but you must hold your hand still, I really don't like XS camera since it's not as good as SONY says, but apps make it better
Multi autofocus makes it a bit better for me also in low light.
i think it will be better if you use touch focus
Hi guys...
How is everyone?
Kindly see the following two pics.
When the focus is on the tubelight the screen goes all yellow and thus the resulting pic as well.
but when I covered the tube light with my hand IT returns to normal the actual colour that is there.
Do any of you guys have this problem how should I get my unit replaced?
Is this even a problem or normal white balance stuff?

It's plainly not a problem.
You may find a similarly serious "fault" where your photo comes out black if you cover the lens with your finger while taking the shot

Sorry, didn't mean to sound so chippy. The fact of it is though that this is not a problem. The phone's software adjusts depending on lighting conditions so when you change the lighting it's gonna change its behaviour. Go take some pics in daylight and other real world conditions if you want to confirm whether it's operating correctly. You can always find ways to catch these algorithms out with artificial situations

I didn't wanna run out of my replacement period and then realise that I should have acted
Yes, this is not a problem, a reviewer showed how the camera reacted when photo was taken from two different angles, at one angle green color was dominant while on different angle it was not.

If you happen to still have your Poco, this condition is NOT a hardware nor a white balance problem on Poco. This is a normal behaviour of the flourescent lighting especially when the camera is using fast shutter speed. The yellowing is a phenomenon in which the camera captures the lower portion of the flicker curve, in laymans term, when the light has just turned ON and is not on its peak power yet.
But why was it using fast shutter speed? It should use low shutter speed!
You have a camera with a sensor that can capture huge amount of light at a given intensity and has the capability to use fast shutter speed in order to not blind itself (to not overblown the image). If you ever do use a slower shutter speed, there is a huge probability of the image of being overblown or for the moving subjects to have trails. You could still make some few adjustments in manual mode.
But my old smartphone renders the proper white color!
It is true, it renders white colors because it might be having a lower aperture, smaller sensor or even smaller photocells. To put it simply, it is using slower shutter speeds because it is what it can do and it is doing well with flourescent. It is not being blinded by the light because its camera configuration is not advanced enough to capture more light on a given amount of intensity, does slow shutter speed.
Put this into your mind: At a given constant white balance, a magnetic ballast flourescent lamp will still emit yellow tint/cast whenever the camera is using fast shutter speed. This is NOT an issue of the camera itself but a limitation of of the light source itself because advanced camera systems were now fast enough to capture its low power phase/state.
This phenomenon DOES show on full flrame cameras ie Nikon D90 and Canon Rebel XSI 450d, due to them having bigger sensors therefore using even more faster shutter speed. This doesn't mean that they're defective.
This phenomenon DOES NOT show on high frequency lamps such as midrange LEDs and mostly Flourescents with electronic ballast.

Thanks for the explanation! I'm having some problems in places with that type of lights but not when pointing to them, just taking a normal picture, same picture can have that yellow tint, or not, just changing from one camera to the other one or moving around the photo a little bit....
I have an Xperia 1 iv but whenever I use the camera on something that is quite close, the screen starts flickering and flashing a blueish colour.
Is this a fault?

Nah, that's rgb sensor measuring the distance or something.
Point another camera at your Xperia 's and you will see this thing glowing.

It's so irritating. Is there anyway to stop it? I find the flickering very uncomfortable to view.
I'm used to Samsung smartphones. Never come across this before.
It seems to take ages to take a photo compared to the Samsung Galaxy S8 Plus I was used to. Why does it take so long?

Not sure how to disable this, as stock camera's autofocus is depending on this sensor. Google camera is not using this, but it's half broken, so I suggest to wait for devs to make a proper config, but I advice you not to bother, as this flickering is rgb sensor highlighting the environment while measuring the depth and it's only for half a second
to establish a proper focus.
As for long time to take a photo, I assume you are using basic mode and device may decide to either use a slow shutter speed or/and hdr based on the light conditions, hence the long time to make a shot.
Experiment with manual modes, phone is capable to take 20 photos per second.
Switch to S mode for example and put a high shutter speed, it will adjust the iso for you automatically if full manual mode is too much for you. This phone is like driving a manual car, no fancy AI to do the job for you like they have on Samsung. Might be challenging at first, but once you figure it out , you gonna make amazing photos.
If this is not related to settings, clear photo app's data and reboot the phone. I had this issue after experimenting with google camera, stock app was not saving photo at all.
