pitch-black photos sometimes? - Nexus S Q&A, Help & Troubleshooting

i'm using the camera to take some photos for ebay... now most of the pics are fine (with the flash firing, everything on auto, 0 exposure), but maybe 1 in 10 will be black. i'm not sure if the flash is mis-firing or what?
is this a 2.3.4 thing or a bug of the nexus s?

Camera Frame Rate - 3 FPS

Go to HKLM/Software/HTC/Camera/Common and change EnableFrameRateInfo to 1
ok now go back to either your camera or video camera and you'll see there's now a little box telling you the frames per second. If you play with it you'll notice that it gets very poor in low light (probably around 3 fps) to slightly better in bright light (15 or so). Either way, these frame rates are probably causing the blurry photos. Not sure of the answer, but this shows the problem. Any one have thoughts on if this is a software or hardware issue or any way to tweak this? If you're getting 3fps then the image needs to be entirely still to not blur...
thanks bugsy. i've tried powering off the screen while in camera mode for 10-15 secs and then turning it back on which seems to reduce some of the camera lag or low framerates and now i can more accurately judge what the difference really was. i went from 3-5 fps, to 15-20 fps.
!
10x for the tip bugsy i never got to 20fps even ouside in day lite so i really
hate the way TP is recording....if you move your hand it records like
crap...found a funny one: while using flash lite the lite is reflecting in the
picture so i try to fix it (take one photo with flash lite in dark and then
take another one with the back cover from TP off ) look in the right side of picture to see the diference ,to fix it i painted with a black marker inside the
phone back cover near camera and flash !!!
any ideas how to fix this? 3 frames per second is a total joke. I can point it at a light and move the camera all over and get 15 fps with all sorts of movement. If I move it to low light I'm at 3fps... 15 is tolerable...3 is almost unusable.

I had noticed that flash reflection too, it really ruined flash shots! Well, I did like you said and took a dark marker and marked the metal part on the inside of the back cover, and now no more crappy flash photos, THANK YOU much for this tip!

10x but not really working for me,but i see that it works for many other people so i think that this have something to do with the battery power then i unchek Auto adjust backlight from power menu then start the camera it shows 8 to 12fps then in 1-2secs it checks it self somehow Auto adjust backlight box automatic and gose back to 3fps .... :-?? so i think the problem is from battery power that camera uses .... !!! (sry for my english )
californiarailroader no need to Thank me mate,i'm really glad i can help xda-developers with something (more or less) !

Dark slow motion video recorder

Has anyone else experience this issue? Every time I go to record a slow motion video the screen gets dark. I can see the video but it's really dim and plays back really dim. This only happens indoors. When I first got the phone I just thought that must be the way it is. However, I installed a particular ROM on my girlfriends phone (HTC Amaze) and it has slow motion video baked into the ROM and it records perfect without dimming itself. Furthermore, it does it in 720p. So there must be a way to fix this in our One S phone's. Someone with enough knowledge please help.
Same thing happens on my One S running on Trickdroid 6.1.0

I noticed it right out of the box. So it has nothing to do with Trickdroid (FYI). But I know there is a way to fix this. I just don't know how to go about it...
Same here. Happened on stock Rom straight out the box. :/

That comes with taking a slo motion video. You need lots of light when taking them. This isn't a DSLR.
When you shoot in slow motion, you are taking pictures quickly. And when you take pictures quickly, light has less time to create an image in your camera. Shoot in lots of light otherwise you'll get the dark and gloomy.
I understand that our phones are no DSLR camera. However, my girlfriend's HTC Amaze can record in slow motion with no low light issues what so ever.. Obviously you didn't read my first post... And it records in 720p slow motion. Better then our One S phones. There is a fix or a camera.apk replacement somewhere. I could use her apk from her ROM but then if I did I'm sure I wouldn't have the "Continuous shoot mode" which I love.
i was using slow motion video thing on my sensation and it was greate one s have a big problem in this case also on new 4.0.4 update too

[Q] Camera Bug

I've been having problems with my back camera.. It can take pictures but randomly only shows a black preview of the picture taken and says "no thumbnail" for that picture or half of the picture shows gray or green colors only and also sometimes force closes.. Front camera works fine and I've already tried different camera apps and different roms but still facing this problem.. I've got no problems using video recording though that's why I think this is really weird..
Hope someone could help me out on this since I've got such an unreliable camera that is randomly usable for taking pictures which is really annoying..
I had same problem when I was on ICS but with front camera. I flashed JB and now it's not even showing black screen, it just crashes
Sent from my Nexus S using xda app-developers app
I finally found out what is triggering my camera not to work properly.. When the device heats up that's when the back camera has issues (maybe since it is located on the upper part of the phone and that's where the phone usually heats up)..
Does anyone have an idea if this is hardware or software related?

[Q] burst camera sucks

This was suppose to be one of the main features for this phone.
When you start to take burst pics it only flashes for the first pic then no flash for the rest, then all but the first pic look dark and crappy.
Is this normal? Or is my phone defective?

I don't think the flash could keep up with it.

it's normal, it was the same on my One X
If you want decent camera performance, buy a camera, no phone is going to be able to give you what you are looking for. If a phone could fire the flash successfully in burst mode the battery would be flat in minutes.
Use a different camera app then, that can have the flash(LED) turned on all the time. ZoomFX is capable of doing just that.
As others have said already, if you want such advanced features as a stroboscope, you will have to pay a lot of money for a good system camera.
Even my, at the time, expensive(~4500sek, google it for currency exchange) H2 isnt capable of flashing the flash fast enough for burst fotos.

[Q] Camera Issues when led flash on.

Hello, i'm from Colombia and my english is not that good.
But i'll try.
27th Dec 2012 i bough and HTC One X at&t from Amazon, got delivered by Jan12 Saturday 2013 about 15:00 hours, retrieved, unboxing bla bla bla, i was testing the device, i came with ICS 4.0.4, Sense 4 and RUU 2.20, everything was working fine, data, wifi, screen, sound, but, when i was about to try the LED Flash of the Camera (to find out if it has AF Assist Lamp, witch it hasn't) i found a very weird artifact
This is it, i took 2 photos to a paper on a tablet.
The left one <-- was taken with LED Flash On (NOT AUTO, ON) and the right one --> was taken with it off (OFF, NOT AUTO)
This is so frustrating, practically there is no way to take photos with flash, is not a hardware issue (i think cuz when i record a video and take a photo while recording with LED LIGHT ON, the photo is fine, there is no such artifact), another way was changing the auto whitebalance to fluorescent and the photo becomes a little decent, and i thoght that i can handlet it, but no, when on Instagram, Facebook Cam, Cymera, etc. There is no sense Cam interface to take Photos while recording a video, neither the auto white balance option to get rigde of the "sephie like effect" so, i decided to change the ROM just to try:
Tried Vyper XL 3.0 and 2.4 and was the same ****, so i decided to reflash the device back to stock with and RUU 2.20, right now it has OEM ROM with Bootloader relocked and no root. and is in the same that was when i got it.
So, the Q are:
Is there another person who has experience the same issue?
Is there a way to fix it? Since i think it is a software problem, maybe yes maybe not.
Thanks.
I was thinking about sending back to LA for Warranty but... It will cost me $74 and a month of waiting.
i searched on Google and here but found nothing.
UP (?)
I don't think there is anything to "fix" here, and the camera is basically working as intended. It looks like just a matter of taking a picture of a completely white frame combined with the flash, which is throwing off the white balance. I'm sure there a plenty of other color/light combinations that will similarly result in odd white balance results. Its just a computer algorithm that is trying to interpret the lighting conditions and guess the "best" white balance, and its not going to be correct all the time.
You've already found the workaround, which is to either turn off the flash, or change the white balance manually. Or you might be able to fix the color after the fact with the built-in editing feature or 3rd party apps. I certainly wouldn't suggest warranty service, and don't think it will fix the problem anyway.
Flash isn't recommended for macro/close range shots, anyway. You get unsightly reflections like the one in your example. Even aside from the "sepia" tone, your second (no flash) example just plain looks better in every way. So why even use the flash, unless you for some reason have a need to regularly take photos of documents in low light, requiring a flash?

Wtf? xd
I have also a Infuse 4G, 8 Mpx too, LED Flash, and the results with the Flash on, no matter if it's needed or not, are as it should be.
But this? here are two more examples, and i just took about 50 pictures, all with the LED On, and the sephie tone is everywhere, from a bathroom with zero light to outside, with sunlight, and even blocking the LED light with the finger.
This is so frustrating. I hope that is there a fix .
Another factor may be that the white balance by default is significantly "over-saturated", presumably by HTC to make colors more vivid and "pop" more. This could be why you are seeing this effect on this phone, when you don't on other phones or digital cameras.
But the latest photos you posted look pretty funky. Also, I've also tried to duplicate the effect by taking a picture of a printed page, and can't get the sepia tint. In fact, my photos actually look more white with the flash (more of a yellowish tint with flash off). These factors make me re-think my previous statement that it is working the way its supposed to.
Does the yellowish tint happen with subjects farther away too? Such as taking a picture of a person or landscape?
Defect with the camera? Maybe.
A "fix" aside from repair or exchange? Doubtful. The fact this issue persists across multiple ROMs suggests it may be a hardware problem.

Yes, no matter what, if the flash is On, the "sephia like effect" persist

I have tried Viper XL 2.4 and 3.0 but not with CM 10 or AOSP ROMs.

Couldn't hurt to try a AOSP-based ROM. ViperXL uses a different camera from stock 2.20 firmware, although its a newer version of the Sense camera.
