Hi,
I recently got the Samsung Galaxy SII and noticed that I'm not getting a clear image from the front facing camera (I'm seeing a bunch of vertical lines). Outdoors the camera is fine, I noticed it occurs indoors (so I'm assuming it's because of low light, although my rooms seem lighted enough) and is more noticeable with a higher screen brightness on the phone and when recording a video. It got me worried enough when I was testing video recording in my room and I was seeing these lines on my face.
I tried searching for answers but couldn't find any, maybe it's because I'm not familiar with camera terminology . Is this what you call a grainy image?
Is this normal? I wasn't expecting quality from the front facing camera anyway, so if other users experience this too then this really isn't much of a problem. The image I uploaded shows the vertical lines I'm talking about. I bumped up the exposure value to get the lines to show more because it looks that bad, sometimes worse, when recording video.
Hopefully this is normal and I'm just being a noob. I don't want any problems on such a great phone! Thank you for any help in advance!
That just looks like noise due to the small sensor, you can try setting the ISO to be locked at 100 to minimise noise. The downside is that shutter speed will be used to compensate so you need to hold the camera steadily.
The phone doesn't let me change the iso for the front facing camera and I can see those lines even before taking the photo or video. I'm just wondering if other users experience this. If not then maybe I need to get it exchanged D:
Thank you for your reply though.
Hi I just got the S3 and I've noticed that my camera is very grainy, much more so than my S2. I've tried fiddling with the settings and can't seem to fix it. I'm wondering, has anyone else has had this and has found a way to fix it? Thanks
Is auto contrast switched off?

Yeah it is. I've tried it with both and it doesn't seem to make much of a difference.
Are the pics at night or day? On my one x the dark images r really grainy. The higher the ISO is set to eg 1200 the grainier they are aswell.
it may be the iso. It was inside but I took a picture of the same scene with both phones and the S3 was very grainy. I think I need to find a mixture of ISO and exposure. At the same time I can't see me getting it to the same level as my S2 which worries me. It's a bit strange.
another thing to check is if the ANTIVIBRATION is set to on
when you set on, you can immediately see (specially in low light) an increment of grain, i think because the antivibration is just a boost of the iso
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

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.!
contrast is not automatic...

automatic contrast does lead to more noise on mine (judging from the preview window)

Yes, In the dark the noise Is more high with automatic contrast...

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
Whenever I shoot macro mode, the pictures come out blurry. I can't even get a good picture of a paper documentation I have on my desk. I tried normal mode, and it also produces poor quality. Anyone else having this problem? I know it's not the megapixels because I always use 3MP on my Note1 and get great usable results.
Also, outside here in Portland we are having great sunny days. I took some shots, but the sky's blue color looks like as if it was mosaic-ed or something. I really wish it had better quality. I know there's a firmware update for the international version that has some changes on the camera performance, but because we have a AT&T crap, we are going to be stuck for a long time.
Overall I love my phone even though there are some quirks such as gaps between the speaker grill and body, and screen/speaker grill are not leveled. Piss-poor quality control even with the awesome uni-body.
Did you try the "text" scene option? I havent had any problems with macro focus

Thinking of buying Alpha.
Photos in Showroom looked sharp but people say in
Lower Light Alpha photos weak, blurry .
However, GSM Arena said in low light HDR and digital stabilization require holding
Phone still for 10 seconds or so .
Has anyone used a Tripod or set the Phone down and used the timer to get
clear non blurry low light photos with Alpha in low light ?
