Are they in the same place in every photo you take?
If so it looks like you may have some kind of contaminates on your lens / sensor.
I'd send it back to HTC and they should fix or replace it for you.
If it was a DSLR you could use a Rocket Blower to try and shift them but I don't think it would do much good on the tiny DHD camera

yes they are. i'll send an email to the shop i bought it in and hear what they say about it

Most likely dust on the sensor. Was it like that when you bought the phone?

Usualy dust on the lenses appear as bigger blurred spots. Those sharp edges on the black spots should mean that there is something wrong with the sensor (dust or a faulty sensor). The fact that they appeared at a later stage is truobleing - it could mean that the sensor is not sealed properly. Have you tried to take a picture at a bright light souse (a lamp for example) to see if they are still visible. If they are that should mean sensor failure. Are they visible while taking the shot or while shooting a video?
Anyway, you should take it for repair, they have to do something for that, but if you are rooted, S-OFF and/or have installed custom ROM, be sure to return your phone to stock condition, because they will void your waranty if they see you have done these things to your DHD.

Hi,
Any news about your problem ? I have the same kind of spots on my Galaxy S and would like to know what causes it...

Hi tkolev! Thanks for the precious info. I have a similar problem with my camera. I see a black patch on a fixed position in images as well as videos. Its just there when I turn my camera on.
Here's my thread.
http://forum.xda-developers.com/showthread.php?t=1403912
FYI When i focus it towards a bright light source, it disappears..

[Q] Is this normal on camera?

I noticed this especily when theres no much light. This is only part of taken picture. With room light, flash...
Also on display, when I wanna take pics those stripes show, dancing going up and down if you know what i mean.
Is this normal for HTC desire camera? I know that quality is not like on real camera offcourse.

I very rarely use the flash, even at night as it's only of any real use on fairly close-up facial images in poor light, and even then it's far from great. I find that a bit of messing around with the settings I can get great pictures in low light conditions.
The best thing that you can do is set the cameras 10 second countdown and sit the phone somewhere in a suitable position to capture the photo. If I'm unable to do this then I'll hold the camera but rest it on a balcony or wall. It's near impossible to get a good shot in low light without doing the above.

Thanks for reply.
I just wanna know if those pinkish lines that showing on display when taking pics are normal? When wanna take pic (doesnt have nothing with flash) on display i see moving lines, espacialy on dark places?
Know that quality of camera isn't great..

Mine doesn't seem to suffer that from what I've seen.

Try cleaning the lenscover. It's not normal really. Could be the CRT's updatefrequency but I doubt it.

I cleaned lenscover, even take pictures without cover. And problem stays.
On bright day , you can't see those lines, maybe it's to much light for them appear.
But when its dark, they shows.
I noticed that those pinkish lines dance more on bottom of the screen , where is mic for talking, and buttons.

Its probably something to do with the kernel. I had something like this when I used Insertcoin Sense 2.1 & 3.0 hybrid.

What you mean about kernel?
Mine is 2.6.32.15-gf5a401c

I didn't do anything to the phone, i bought it this way, so i don't know if anything was installed.
Is it fixable? And how?
If need any more information, im here

Okay, looks like you are using the stock rom and kernel that came with the phone so I don't really know why you would get this kind of problem. To tell you honestly the first thing I did when I got my phone was root it and flash a custom rom so I never really knew how the stock camera performs under low light conditions.
I do however experience this when I used custom Sense roms before.

I bought this phone of seller who sad that he didn't do anything to the phone. And then i found out this
BRAVO PVT3 SHIP S-off

MICROP-051d

It's not rooted (don't see superuser icon?, i think thats how you know it's rooted )
Maybe this have something with camera??

It does say S-OFF so maybe you should reflash the stock RUU just to be sure. You never know what the last user did with it.

But you have to flash downgrader before you flash RUU, because you use one of alpharev's r2 hboots (probably CM7r2) and these ones have an overwrite protection against RUU and OTA.

I had this problem when I flashed a ROM with Sense
As soon as I flashed the CM7, I had no more problems with the camera.

I had this problem when my Desire was stock. I broke the screen and had it replaced. The tech damaged the flex cable when he was replacing the screen which resulted in the funny lines and other camera issues and screen hangs. Luckily another tech seen it when I returned and it was replaced again.
I'd say your trouble is hardware related.

Thanks for answers.
So you think is fixable that way?
But unfortunatly I can't do downgrade, and flash RUU, because my computer restarts sometime (something to do with motherboard), so I'll have to wait to get other computer for about month and then try do downgrade.
I'm afraid that will restart in middle of process, and brick phone or something. If phone can be broke that way???? If not I'll do downgrade right away..

I don't have any other problem with display. As i read, you have?
Only when I start camera it show those moving lines, on taken picture when there is light you almost can't notice them.

Yes but only when using the camera. Lines, image off centre weird colours and sometimes just freezing when running any camera app.
It could be software related bit I thought I'd share what my problem was in case it was useful.

Hey, have you checked the ISO on the camera settings? Very high ISO can cause that problem...try Auto or 100.

Yes i tried to change ISO settings. Problem stays.
I also found out when sometime i take close up photo with flash, i don't see those lines, photo is clean...

Pink spot at the center of every captured picture and video !

I have just noticed that there is pink spot on the camera
the attached file shows a picture of a white wall .is there anybody else who has the same problem?do you think it's a software or hardware problem ?

I seem to remember there being an issue with pink spots in the center of photos in some phones. I'd take it back to the store & exchange it if you're within your 2 weeks, otherwise call T-Mo & see about getting a warranty replacement.

too late to exchange? If not.. I dont know why you're still online and not in the store lol

it's too late i have had this phone for a month now,and just noticed this problem ,
been distracted with the faulty screen (vertical lines and blobs) for that issue i had to send the phone to samsung repair,
and now i have to deal with this issue,I don't even like to use this phone anymore !
so disappointed with samsung

so Does everybody think that it's a hardware problem ?
I just found out that the 1st device i got which i had to exchange because of the screen blobs had the same camera issue(pink patch at the center of the picture)while i was reviewing the pictures taken by that phone !

I only notice this issue with a reflection of natural light and no flash. Are you taking the picture with flash?

That's the white wall with Auto everything, no flash under fluorescent lights.

the reddish picture is no flash with fluorescent setting for white balance.
The one with bright spot is auto everything with flash on a white wall under fluorescent lights. I think the problem is with the software tries to adjust the white balance.

Deng you I just took a picture against a white wall and I have that issue also good thing I just got the phone a week ago,

Try the miui cam.apk on your phone and see if it makes a different.

i just performed a test and think others should try this. I noticed you guys took a pic of a white background or wall so i did same thing regular lighting no flash, and aimed at the wall i also seen the pinkish spot but as i panned my phone around it would fade away then come back as i panned. so then i took a still shot with flash off and had the same result as op. then i did the same thing with flash on and no pink spot at all. so i definitely think its a lighting condition that makes our phones show this weird shade or color. more light = no pink spot. but its weird cuz it seems to only happen on lighter backgrounds like a white wall and such. because that is the only time i ever noticed this anomoly. and ive took a **** load of pics of my 1yr old boy, and girls

i honestly dont see it as a big deal as this phone takes great pics

I used the miui cam still there , idk the issues on this phone are small and idk how I really feel about it haha I've only had this phone a week so far, came from a non issue g2x wich I was lucky

I see the pink spots at the center of the pictures under the day light ,and those spots turn greenish with the florescent light at night !
I think that affect the pictures quality ,
not sure what to do

Look here: http://pocketnow.com/thought/clarification-the-pink-spot-syndrome
Also note that sometimes it's green instead of pink.
I'm much more concerned about the blobs and lines.

The key difference is this camera issue can most likely be fixed in software, but the blobs/lines is probably a hardware issue.

Camera Fault - Yellow tint in corners during the shot and in the pics ?

Hey all,
I'm new to the forum. Did a search for this but did not get any hits.
I had an issue with one corner of my screen perpetually displaying a yellow tint while using the main camera that also translated onto the actual pictures.
Didnt see this on the front camera. So I assumed this is a one of hardware issue.
The dealer had the phone replaced 2 days after I bought it with a new piece (Part of their 7 Days - No questions asked guarantee). So far the issue hasn't surfaced.
I've tweeted HTC, but haven't got a response yet. Here is a pic with the tint in the top right corner - pic.twitter.com/epsvQRlP
Has anyone experienced the same issue. I know I've already got a replacement but in case this crops up again. I just wanted to make sure that this is a hardware fault.
Awaiting your thoughts / experiences.
Cheers.

well the yellow tints appeared on mine after 3 days of use. I replaced it with a new one. Thats all i can say, Some other people faced the same issue but told me that they waited for another week and the tints seemed to dissapear after some days.

Can you post a photo indicating the issue?

Compare the top right corner near the couch and curtains to the bottom left. The room was evenly lit.

I had yellow tint when I used the flash, but this only happened withthe flash returned and got a replacement still yellow not as bad but had gps probs so replaced that on 3rd started off yellow with flash but now when I wait for the metering to settle down seems to be ok so seems third time lucky for me

Lets hope the second times a charm for me. And if there is a recurrence, it happens before the 7 days are up....
I'm interested to know what the experience was like from someone who had the issue go away after a couple of days. It kinda sounds like a break-in period for the camera sensor (similar to buysing a new car).... Has it completely vanished after repeated use ?

Can you take a picture of pure white background e.g. like wall, sky?
Sent from my HTC One X using XDA

need a couple of pictures to see the problem! one picture doesnt help

My newest one x has this problem, any improvement with the latest ota?

I only see a yellow tint with shots taken indoors. Outside they are just fine.

My One X got the yellow problem when using the led flash. Comparing to my old desire, the flash in one X is more yellowish. It may be able to be rectified through software updates, setting the correct white balance for the LED flash. Hope HTC will solve that through the next update

try camera options, image adjustments, saturation set on -1

got the yellow **** when shooting with flash me too... without flash the pic looks ok, but when flash is on, skin become yellow, very ugly

I think your problem is linked to the white balance which is ****ed up.
I take some screenshots of the camera app phone with different white balance option like bellow:
The photos is taken without flash in front of my wall which is normally white.
Only the auto option is OK for me, the other options shows my wall yellowish or blueish.
I don't know if it is caused by the Eternity's kernel in my phone, have you have the same issues ?
Edit: No I didn't painted my wall in yellow or blue

same problem for me ... when I use flash it shows yellow photo ...I asked in service station but they say this phone is not to take pics in dark.. not ready to change phone.

Ok, I took some pictures outside and I can conclude the white balance option should be used at outdoor condition.
There are a few differences on the white which can be colder or warmer between the photos but not as strong as the screenshots above.

this is bull****... my sensation is making normal photos with the flash, no yellow ****, its something wrong with the one x...
just installed CM9 to check if it is something about the libs, but the issue is the same with CM9... so its not rom related.

tried with different white balance settings, but it does not help the flash issue... :/

Camera flash issues

I find that the camera flash is inconsistent when taking photos and makes flash photos appear muddy or white balance is off because the camera is not taking the picture at the right time. Examples below.
No flash

Using the app flashlight forcing the light to stay on during capturing
As you can see there is a quality difference but i wonder if any one else has this or if there is a fix ???.

Bumbide bumb

Great question, but I believe flash is handled by the Imagechip, so it's probably a driver issue, therefore if there is no setting exposed in the camera app to fix this, then the only fix can come from HTC.

My photos with flash are always yellowish.

@Op,
Reason is simple.
Flash on a smartphone or any other device doesn't make sense to my opinion.
Maybe for some situations it will work but for most it won't on a tiny device with such a small flashlight.
Why do you think pro camera's have external flashes?
In most situations it's better to use the camera without flash.
The only reason you need a flash is to shoot a moving object in low light conditions to get it sharp.
The object should be very close as it isn't possible to have a flash light so strong (with such a tiny bulp) that it can cover a distance further then one meter or more.
Actualy I don't know what the maximum distance is with the flash on hox but everything after this distance will be dark because the light stops in a couple of milliseconds.
If the object isn't moving you don't need a flash, only a slower shutter or larger diafragma to catch the subject in low light condition.
It would be cool if HTC would make a socket for external flash in any futher device. :laugh:

If i'm not mistaken from what HTC said this is the first smartphones implemented with smart flash. The auto-flash's brightness is auto-adjustable accordingly on the object distances and enviroment brightness. They only mentions this on MVC, but not on ads. Wondering why, maybe could lead to IP issues.
Please note that I am not commenting on the photos quality, just telling what I know.. Pretty interesting features, you may try it yourself..

That the white balance is off is very logical.
Or did u change the balance before taking the shot..

Yea your right but some people make use of that, like sometimes i might want to go out to my car at night to take a picture of a book or anything impartcular or when im out with my girlfriend in th dark and we take pictures together real close. I do understand however it does nothing for widespread shots.

The white balance is off because the camera misfired at the wrong time and captured the light at its weakest output.
