Anyone notice this strange problem:
After updating to Froyo, about 1/4 of the time when using the camera flash, I get a dark picture. The flash goes off every time it is supposed to, but the camera sensor takes the picture after the flash goes off, resulting in a very dark picture as if the flash was disabled. Take another picture and it usually works.
Happens in stock camera app and 3rd party apps too.
2.2 rooted, stock rom, etc. (Happened before I rooted 2.2)
I've noticed this. What else I've noticed is that the photo may be dark, but it's still very high quality. It isn't grainy and rough like a photo taken without a flash. It leads me to believe that the camera is adjusting the settings to take more of a "true" lighting with high quality.
It's not -- I often take pictures inside a dark bar at night and you care barely see anything on then and it's a noisy mess. I did some more test shots yesterday and it really is really is funny the EXIF data shows the flash being used, even though clearly it wasn't synced up properly.
I also notice that it is usually the first pictures or so when you start the camera. If you take many successive shots, it doesn't happen........
I tried switching from 3mp to 2mp to see if that helps. I find the lens to be pretty low resolution that even 3mp is pushing things.

I'm having a problem in the sense that the camera seems to only take octure after the flash turns off. this is when the flash is set to auto mode. as a result my picture looks darker with the flash on then without. anyone with this problem as well or any ideas what to do

I noticed same thing. Looks weird for me too. No idea how to fix it. The problem not always exist - photos are ok when I shot in total darkness with flash. If i take photo with some light then it looks like after flash turns off.
Anyone else noticed that?
No, this is normal. It reduces the exposure time when flash is on, so that pictures do not get overexposed. Every camera does that.
As a result, you may get darker pictures with flash than without, if you use the flash at times where it's not needed. Just turn the flash off then.
I noticed this too, as in the flash fire and the camera shoots but the image from the preview that remains on screen for a sec if for example you press delete, looks better than the actual photo.
It's like the camera needs to capture the image a few milliseconds quicker or something.
No no no. You all got it COMPLETELY wrong. I already gave you the explanation above.
It takes the picture exactly at the same time that the flash turns on. It does NOT shoot too late.
It just reduces the exposure so that the pictures don't get overexposed. ALL cameras do this!
Sometimes, however, it uses the flash when it should not. These are the times when pictures would turn out better with the flash than without because the flash cannot compensate the reduced exposure time. Just turn off the flash and everything is okay.
This happens with every camera that uses auto flash, but it happens particularly often with mobile phones that have an LED flash. This is more or less normal and you can't do anything about it, except for turning the flash off manually.
Anyone seen or heard anything similar to this? I'll open the camera app to take a picture and the view looks ok. Once I take the picture it comes out discolored, sort of like it has a retro effect on it. It mostly happens when using flash, and once taken the view shows the retro look from then on until I restart the app. I've tried other camera apps and get the same thing.
Ive uploaded two sample pics, the first being an example of any picture I take with flash(and the view I see until the app is closed) and the second is a shot without flash. Even though that picture is of a lit tv, lights on in the room and the kinect sensor pointing at it, that picture discoloration happens in any room with any type of light.
Any ideas? Thanks!

Well, the green discoloration is from the invisible green laser the kinect is giving off, which has likely damaged your camera.
I've heard of this happening with DSLRs.
It was happening well before I put it in the same room as the Kinect though. The 2nd picture shown(without flash) doesn't have the discoloration, and was taken just seconds after the first. Is there something different the camera does when using flash that could be damaged? Seems to take pictures just fine without flash.
are you taking this thru the built in camera app..
Do you have any other camera apps installed are all the camera settings set to stock..
these are things that could effect camera / camera flash quality.. i had similar issue after installing a cam app from market uninstalling that app solved it.
dont remember what app it was sorry
If you are using a case, It may be effecting the flash; I know when I use the stock camera app with flash in a dark room it gives a greenish tint, over the whole photo, when in the case. Taking my tablet out of the case fixes the issue. Probably the thick case bounces my flash across the clear protective glass over the lens. Your picks look a little different though.
When you get the greenish screen, instead of closing the app, try toggling one or all of the three---white balance, color effect, or scene mode and see if the screen reverts to normal.
Just tried changing the settings before and after taking a picture. It seems the discoloration happens only when scene is set on auto and flash is on. Changing from auto to incandescent with flash on takes normal pictures and fixes the screen discoloration. Switching back to a different scene setting and back to auto fixes the discoloration until you take another picture. I'd say it's software related but its happened on 3rd party camera apps.

If you havent already,..... take it outside into Natural sunlight. Set flash to always on(just to test) and every other setting to auto. Take a few test pics. Some close-ups and some landscapes to test the colors. My guess is the outdoor shots will look fine.
I've been having this problem when every few photos, just a plain green picture is taken. And sometimes there are distorted colors. I decided to play around with the settings to check if it changes anything.
I found out that the problem is keeping the focus mode in Continuous Auto focus. Keeping it in this mode apparently has problems which are the green photos, distorted colors, and around 2 seconds of lag between the shutter and the photo being taken.
Keeping it on Auto took off 2 of the problems which were the green photos and distorted colors. But it was still kind of laggy, I think it's supposed to be this way though to have time for it to focus
Putting it on Infinity fixed all of it, I took over 20 photos without any problem or lag.
I don't know why that problem occurred, but it's probably just the camera firmware and not a hardware problem.
Hope I got to help
I have the ATT Galaxy Note 3. I've noticed that my pics are a mix of focused and blurry even when I get the green square.
Yesterday, I went to take a picture and it focused very clearly and offered up the green square. When I tapped the screen while holding it very still to take the picture, it went to focus again and snapped the pic at one of the worst blurry moments instead of waiting another second to get clear again.
It does this on AUTO setting and HDR setting and whether stabilization is on or offer..doesn't matter. It still happens.
A second question, why would the auto-focus leave me with a red square instead of a green one?
Are you using the standard app or another one? I use Camera Zoom Fx. Might be worth a try. Also, for whatever reason, a red box would indicate not in focus, if green indicates focus. I found the Samsung camera app to be terrible.
Don't use the stock app. Use another camera app. ZoomFX, ProCapture, FV5, Shotcontrol... Anything but Stock. Stock is rubbish.
1 problem with stock camera, it doesn't has the option to select macro focus.
Anyone else observing that when they take a pic with the flash on in "medium" light conditions, the photo comes out actually darker than if the flash wasn't even used?
I swear the timing of the flash is bad on my S5. When I tap the button to shoot the photo, the flash turns on and the image on the screen looks bright and good. But then I think the photo is actually taken a split second later after the flash has turned off, and the photo that gets taken is dark as hell. I think I've tried all the combination of settings in the default S5 camera app, and nothing helps.

I haven't seen this with my S5. Unfortunately you didn't elaborate on your camera settings, camera version or other crucial details.
At a guess, and it is only speculation since we don't have your details, you are expecting the flash to act like a fill flash. When the auto mode (which is probably what you are using) probably uses the flash in a conventional manner i.e. a fixed shutter speed (or limited shutter speed range). There are good reasons for that, but the net effect if the subject is outside of the flash range is that little of the flash is reflected back and the (presumably) higher shutter speed lets less total light in resulting in a darker picture.
You can test that thesis by taking some pictures of a subject that is very close to the camera. If the problem goes away with close subjects that implies that the problem is an artifact of using flash for a subject that is too distant for the flash to work with. No flash can work at an unlimited distance which is why people using a flash in a stadium when they are 75 meters from a subject is silly. In this case, flash mode simply isn't appropriate to the situation you are using it in and you'd be farther ahead to use a slower shutter speed, without flash.
It's highly unlikely that a bug would see the shutter opening after the flash.
.
It happens with literally *every* combination of the settings in the camera app (with flash set to "on"). Auto mode, beauty face mode... actually, are there any other modes that I'd use to take a picture of something 3 feet away in a darkish room? I have panorama, "shot & more", virtual tour... those wouldn't be right, correct? So both beauty face and auto, with all the combination of settings... hdr on/off, stabilization on/off, iso at auto and all four "manual" options, all three metering modes... nothing makes a difference.
The problem is the same all the times -- it's not just that the non "subject" areas are dark -- the whole image is dark, just like if you turned off the light in a room and snapped a pic at the moment when the light was still on at 50% brightness as it's turning off. It's super annoying just because of how damn good the image looks on the screen when the photo is being taken... it even seems to "snap" the shot at the right time... the shutter sound goes off and the little border animation happens when the pic is nice and bright. Then I open the actual image and it's garbage.
I was hoping someone might know of some setting in a config file somewhere for a delay between when the flash is triggered and when the camera attempts to capture the image, and that maybe mine got changed somehow to a larger than optimal value.
My wife has an s5, I'll have to test with hers and see if it suffers from the same problem.
Long story short: the camera is using a fast exposure time to keep the subject from being "blown out", i.e. overexposed, when the flash is used. That means that the foreground is going to be sharper but anything in the background will be lost in darkness if the ambient lighting is low. When you leave the flash off, the camera will use a longer exposure time (or shutter speed, if you will) to allow enough light, which also lets more of the background be seen in the picture.
Another thing to consider is that if your screen is set for auto brightness control, you will not have the same brightness when viewing the gallery pictures that you will when looking at the camera view. The camera view is full brightness at all times, but if you're viewing the pictures that you took in the gallery, screen brightness will drop down according to ambient lighting. Photos definitely look dark if you're looking at the gallery by lamp light.

That's interesting stuff, but doesn't really apply to the problem I described (at least the first part... the screen brightness setting stuff is potentially related, but isn't in my case). The exposure time is fine, it's just **when** the exposure starts that is the problem... a little too late, IMO. Really wish there was a way to adjust when it takes the photo in relation to when the flash is fired.
The foreground objects aren't lit up at all. No difference between foreground and background. Sometimes, I'm taking a picture of a t-shirt laying on a flat surface from 2 feet away. Without a flash it looks pretty good, but it's a little dark so I decide to try the flash to see if it'll lighten it up a bit. Instead, it makes it look like I turned out half the lights in the room.... way darker than no flash.
Same here, three friends of mine too.
I'm having the same problem s5 neo
I just figured out how to correct the pics from coming out dark. Go into camera-settings-exposure value-slide to the right to 2.5 or more.My pics come out fine now. Indoor light normal daylight.( with flash off.) I will know more in other settings (places ,situations )if it needs to be tweaked again.
no problems here
my settings are AUTO MODE
flash AUTO
no effets at all
and still i get good shots in night
Power/current draw issue?
Mine was doing this, and I noticed the first flash (ranging) was fine, but the second flash (to illuminate the image when taken) was much weaker. Whilst plugged into charge, repeated low light experiment, and the low light flash illuminated image was fine!! Maybe battery on its way out?
