About the update, you maybe right.
[MENTION=4386647]Riyal[/MENTION] have ask me to test this stuff back then in 4.1.2 when he 1st discovered this problem and I don't have the issue back then.

after reverting to stock and OTA update to 4.2.2, I've noticed this problem but not sure when it appear.

If I'm not wrong, riyal having this issue since 4.1.2..

there a chance it is hardware issue and a chance software issue, let just hope your work with Riyal will turn out as good magic for us with the problem. :)

[One (M7) Q&A, Help & Troubleshooting] michelsaiful:
All the sensors are made by same manufacturer?

Maybe 20% of them was made in a manufactory and the other 80% in another manufactory. Maybe they are similar but not identical.

So, it can be hardware issue (80%? wtf? maybe low quality components?) or some not optimized kernel/driver side code issue.

[MENTION=4647967]Guich[/MENTION], you're one of the lucky 20%

However, I'll bet a beer that is hardware issue.

(ps: I'll sell mine for an S4)
[One (M7) Q&A, Help & Troubleshooting] michelsaiful:
mmm

if it is a hardware problem (heat that causes some noises or faulty camera sensor) why when I focus in a bright area on dark room the black are black? I mean, if the sensor is too sensitive and generate false color (ultraviolet -> violet) why not in all situations?
[One (M7) Q&A, Help & Troubleshooting] teri.nk79:
hi all!

I repeat once again!

if you have problem with camera, you should go to HTC center.

I and my friend ( >5 because I have club HTC One in Vietnam Asia) have a problem with camera. I and they go to HTC Center. We was replaced new camera.

Now, I and they no problem! Htc One Good Perfect!

I suspect it's a software/firmware thing, not hardware. I used to not have an issue but now after I've updated to the latest firmware and 4.3, I've got full on red screen in the dark.

So I was going to downgrade today to stock Sense and try to figure this out but when I loaded 4.1.2 my touch screen no longer worked! Due to I also upgraded firmware that included new touch drivers, so I guess I'll have to RUU. I hesitate to do this though because because I have trouble transferring my nandroid backup to pc, don't want to loose everything.
[One (M7) Q&A, Help & Troubleshooting] Guich:
If this is an hardware problem, all the One will have this.

And why, in a lot of phone the issue was shown after the update to 4.2.2 or the 4.3?
[One (M7) Q&A, Help & Troubleshooting] Thug_4_Life:
Got my HTC One back yesterday after the repairment. The same problem persists.

They said they replaced the whole camera. At this point, I can only say that this is not a

hardware issue. Very much disappointed though... This phone has cost me a fortune

and I can only expect more.
[One (M7) Q&A, Help & Troubleshooting] onisajo:
the white balance not working as it should..

using auto white function (avisynth filter in avidemux video editor) to easily returns all the black for video and photo without adjusting anything else(color, brightness, saturation. etc)...

so i think it can be fixed / improved with software..
[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
Reasons to believe it is hardware so far:

-Can be induced by heat (physical induction means physical problem)

-On both Google and normal editions

-Independent of batch and factory

-On all versions of OS and firmware

-Worsens with time

-Replacing the sensor temporarily fixes it

-Replaced sensors seem to begin to develop it again with time

-It is well known that some image sensors are more prone to this kind of heat noise

Why do some phones not have it? Could be luck (a few better sensors in an ocean of not so good ones), maybe it hasn't developed yet (we know it gets worse with time), or maybe there's actually more than one problem going on here. The last possibility is interesting because while everyone seems to have the color issue, some aren't as impacted by factors, some have other patterns of noise, etc... It's hard to say.

But I can't imagine it being entirely software given the above. If course there's probably no reason you can't fix a hardware issue like this with software, and we would all be VERY grateful in sure if you were able to do this! So I wish you good luck in working on this my friend!! :D
[One (M7) Q&A, Help & Troubleshooting] mrhahn98:
exactly my points, it seems like a design flaw in the camera itself

alot of people have this problem even before 4.2.2 update.

also for the hardware question, remember the red ring of death on the original Xbox360? not all X360 have it, just most of them, but still, the HOX have problem with flickering screen before, we all thought it was hardware, then it was fixed via a new software calibration, so there's still hope

and have anyone tried the new 4.3 rom yet, is the problem still there ?
[One (M7) Q&A, Help & Troubleshooting] MasterThiefGarrett:
Apparently it's still present in 4.3....
[One (M7) Q&A, Help & Troubleshooting] cangia:
ARHD 20.1, still same issues..
[One (M7) Q&A, Help & Troubleshooting] gustav30:
My personal feeling is that its a problem that can be corrected via kernel and camera libs. Why some are not affected I don't know, but it was proved early on in this thread that making changes to the kernel got rid of the pink/red noise. Granted it introduced some other problems, but I believe at the time everyone thought 4.2.2 was going to solve it, so making changes to the kernel was halted at that time.

I'm hoping now that going back to look at the kernel more closely will help. And thankful for Geich and Riyal for taking the time with this.
[One (M7) Q&A, Help & Troubleshooting] shaaXo:
Anyone investigated how autofocus affects the problem? I can clearly the red noise effects effen in plain daylight during autofocus and when shooting a picture without using touch to focus beforehand, the noise is present is most of the dark shots. When focussing first and shooting slightly after autofocus, the pictures are perfect...

Some other people have no noise during the autofocus process but when the image is focused the noise appears.
[One (M7) Q&A, Help & Troubleshooting] cocori002:
I think the purple photos are because the sensor receive much light and burns the sensor, Hence cell phones repaired at few weeks again have the issue.

And yes, can be a software bug.

OMG poll results:

82% have the issue.

17% is very lucky.
[One (M7) Q&A, Help & Troubleshooting] reycharlesconrad:
Hi. Can you please confirm below:

1. After the repair, did HTC reset your phones like it is new and that you have to set it up all over again?

2. After all the repair done, has anyone in your group tried to flash a custom kernel and ROM again like 4.2.2 or 4.3 leaked ROMS? If yes, can you confirm if they did not have the purple issue back?

Maybe by answering above we can try to get a clearer picture if this is really hardware or software issue.

Meantime, I got myself a Butterfly S and it doesn't have this issue. My one has so much worse pink even if flash is on in dark pictures.

As for me whenever it's dark, I just set flash on. Well at least it can take clear pictures in the dark. And I don't use camera that much, but it is somehow bothering.

Charles, you have a good point there.
[One (M7) Q&A, Help & Troubleshooting] htcm7:
I think the problem are in software and hardware.

I suspect, sensitivity on camera's sensor on HTC One not all the same. That is why, using same software, some has a purple tint and others doesn't have.

Probably if there is a software for user to calibrate sensitivity on camera could fix the problem.

Htc will repair the camera if I unlocked the phone with htcdev or the warranty is void?
[One (M7) Q&A, Help & Troubleshooting] gustav30:
If you have done s-off with revone, relock the phone via revone. HTC doesn't know you've unlocked via htcdev, only that you requested a token to unlock.

So if you use revone to relock before sending in, you should he good.

Hi,

I've received my HTC One yesterday and I have to say it's a beauty and it's fast. But it's also suffering from the faulty cam sensor, and it would be a showstopper for me if that's not fixable. I just sold my Samsung Galaxy S3 because I don't accept faulty HW for €600 (it had the 'insane chip'), and now I get this :(.

I did not read all 80+ pages, so if the answer has already been posted I'm sorry, but is there anyone who had the sensor replaced by a decent one, and is still problem free after let's say 1 month? Did you use HDR? Did you upgrade to the latest HTC firmware?

I'll probably ask a refund tomorrow morning, I don't have a good feeling after reading this thread.. How on earth can HTC release it like that and advertise the supreme cam capabilities? :( #acceptanceTesting?! #somebodyShouldBeFired

Diederick
[One (M7) Q&A, Help & Troubleshooting] yanggame:
My camera was fixed after...

1. I spoke to 2 different technical support representatives to request a repair

2. I spoke to 3 different technical support representatives because the repair facility couldn't find the problem, which is unbelievable because the problem was obvious and all you have to do is just open the camera app, put it on the desk, then the screen will became purple in 2 seconds.

I got my camera back, and I also found they're some little tiny scratches, chips, and a dent. So I have to contact HTC to fight this low quality repair service and ask HTC repair it again. This is very long process. I spent 3 weeks to send my phone to HTC and get it back. I guess I have to wait another 3 weeks to get it back to be again.
[One (M7) Q&A, Help & Troubleshooting] ahmedhzaki:
I own two ones. Both had this issue. I called the service center here in egypt. He asked me to rest the phone for 20 minutes and then try again and see if the pink colour presists. One did actually become flawless. Thank God while the other still had the problem. Thought i shouldd share my ecperience. I seem to think its a software problem as the one without a problem has the 4.1.2 installed. I also noticed it worsens with time after a few seconds it turns completely pink. I also have this question how much did it cost you to repair this issue ?

When I made the report about my wife's HTC ONE has purple tints, HTC Indonesia said they know of the problem and that the spare parts were already on the way from Taiwan, but 10 days later, still no news from them. Flagship phone with no locally available spare parts. How nice.

God knows how long I'm gonna have to wait. Bottom line? This is going to be my second and last HTC phone. Hope Huawei eats them up. At least their svc centre here is so much better.

If anyone from HTC is reading this, just to let you know, HTC Indonesia is doing a S*** after sales job. Do a search on local forums and you'll see so many complains about defective products. They bought a phone, few months later, it goes into servicing for 2-3 months. Now don't get me wrong, defectiveness happens, but BE RESPONSIBLE FOR IT and BE QUICK ABOUT IT!!!
