My front cam suddenly started acting wierd. When I take selfies with sky in the background, the sky area is intemsly over exposed and when I focus the sky, the subject and everything else turns completely dark. The exposure balancing is screwed up for some reason. It doesn't matter when you take photos, the sky appears like it is flashing intense light towards the camera making the subject less visible. Even if HDR mode is enabled, the issue persists. Is it a hardware problem or a software problem?
We can clearly see the problem when compared with the results from the rear cam which works finely.

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.
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.

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
Not sure if this applies to other ROMs wtih sense, but on the verizon-deployed ICS OTA the Sense Camera seems to be brain dead if you try to take a normal aspect ratio picture (Read: not widescreen). Verified on another rezound with the same OTA.
Noticed this as the Sense camera defaults to widescreen "8mp" - when you actually get pictures cropped to 6mp. Not caring much for the widescreen anyways, I turned it off. Over the next few weeks, I discovered the previously stellar photo quality start to tend towards overly dark and ill focused - auto focus in particular was brain dead, especially at macro resolutions, where I had previously tested the camera being able to focus perfectly at about 2-3 cm. It'd take me messing with lighting, varying distance, angle, etc, to maybe get it to focus - most of the time it would either stop focusing before or after the ideal focus.
On top of the focus issue, sometimes the exposure calculations would be completely off, usually when there was some light shining at the camera - for instance, from a display. Amazingly terrible, overall. I'm pissed it took me so long to notice and figure out the cause. I was worried it was the camera hardware itself wigging out.
Downloaded another camera app - ICS Camera - and it took pictures just fine at the full 8mp resolution (non-widescreen). Focus and exposure calculations working fine. Oh, and it supports using the volume keys as shutter buttons, which has been something I'd been looking for for some time. Only noted problem is that it does not work as a camera data provider (ie. attaching to a message) - fails for some reason. Otherwise, it's replaced the Sense camera entirely for me.
Attached are pictures of one specific instance. Sun did decide to poke out at the end, but it didn't cause a major difference in the pictures as I was in a shaded area the whole time.
Notes:
HTC-initial is spectacularly bad, even for the addled state the camera was in.
HTC-best is the best i could get the camera to do, mashing autofocus a few times and messing with manual exposure.
HTC-widescreen is the first picture I took with me setting widescreen and everything else default. AF was done once, automatically.
ICSCam is the first picture I took w/ ICS Camera, no settings changed. AF once, automatically.
TLR; Sense 3.6 Camera does not handle 4:3 aspect ratio correctly; AF tends to be poor and exposure off.
Zig zag... That's a very fine analysis of the camera focusing problems I've been having. I've been quite upset with the camera behavior since the ICS update. On GB, the camera functioned remarkably. I'm an avid photographer and even have a Canon DSLR. I was loving the camera on this phone. Never used widescreen. Just stuck with mid-high resolutions but never full 8mp. Sensor has it's limits. Touch focus, just once regardless where I touched...it was clear. Ever since ICS....the camera app lags and the most important thing (Focusing), has gone to s**t. I have to keep touching all over the damn screen just trying to get it to focus on an area I want it And yes, very close shots are hell now. Just last night, I was about to throw the damn phone because it refused to focus on something I used to normally have no problem with. I have no idea what the issue is but it keeps adjusting the exposure level way too bright, sometimes too dark. I'll touch a bright cloud in the background and suddenly the exposure jumps 5 points and burns out the sky. The complete oppositte of what it's supposed to do. Hell frustrating. Has the same focus/exposure problems in Camera360. Yeah, being as bright as it is outside...I was pissed when I got home and found a pic of a cloudy horizon and a canal in front. The entire pic was completely out of focus. The camera AI is so dumb that it habitually withdrawls the focal point to the macro view...even when trying to focus at infinite.
Hmmm.. does one need ROOT for ICS Camera?
I don't think you need root. Here's the link: https://play.google.com/store/apps/details?id=com.moblynx.cameraics&hl=en
Honestly, I'm surprised that HTC managed to break autofocus and auto exposure - when I was looking through android APIs it seemed like those functions were all done below the level at which apps can adjust them. At any rate, using the ICS Camera, autofocus and exposure function just as well as they did on GB, once more. I'm assuming other apps would work fine as well - just something affecting the Sense camera only.
Hmm..it works well. Thanks for the link. Only thing I don't like is it's missing Saturation, Sharpness and Contrasts controls..also missing ISO setting. Tells you image size in megapixels instead of resolution. I haven't actually snapped a pic with it yet so I'll give that a try in a bit. I'm going to give the video recordibg portion a shot and see how the quality fairs out as for sound.
Hi guys, I tried looking everywhere but I haven't been able to find any info about whether or not the wide angle lens has any focus (autofocus) or even touch focus? Or is it fixed at infinity only, with no focus? Or maybe my camera is broken? For example if I put the main camera close to my leg and focus I can clearly see the hairs, but if I do that with the wide angle it is blurry (however things,far away seem clear). If I touch the screen while in wide angle mode the green focus square briefly appears, such as with the main camera, but it does not focus neither does it make the focusing sound.
Also the front camera has no touch focus or autofocus, right? This is driving me crazy, and would appreciate anu feedback so that I know if I should send my phone back for repairs or not. I heard that some G5 phones are suffering from hardware failures regarding the main camera focus, but I want to know if the wide angle supports focusing in the first place. Thanks guys, I really appreciate it!

Hi,
I can see you have already created a thread on this here

so I'm going to close this one up

The cameras on the Mate 10 are great, but would definitely benefit with some more tweaking. The primary camera performs really well and offers fine tuned control over almost all the variables. I've found that the auto-exposure in low light raises the ISO quite a bit and the picture ends up looking fake, plastic and grainy. This can easily be fixed by under-exposing or by lowering the ISO in manual mode, but only with the primary camera. The front camera always seems to expose for the face. There are no controls to set exposure or focus, and there is no manual mode. Although it performs well in good light, the results are poor in low light and the lack of any control restricts any creative photography. For instance, if I move the camera off my face, it exposes for the background but it doesn't lock. The exposure switches back the instant I reframe the shot. Is there any workaround for controlling the front camera besides using another camera app?

I have the same problem, the front facing camera is almost unusable where there is a lot of light.

I have installed open camera, and this app let me lock the exposure of the front facing camera.
any solution found of this? i can hardly use the front camera because of this issue
The front facing camera on the Mate 10 Pro is great for taking outdoor selfies, as long as you want a solid white background behind you. I can't believe more people aren't complaining about this and that there isn't an official fix.
