Just got off the phone with a HTC Tech support guy and was told it might be fixed with a software update, but it also could be a hardware issue and I could send it in if I wanted to.

Anyone else get the feeling HTC is going to botch the handling of this issue?
[One (M7) Q&A, Help & Troubleshooting] LeClair:
Local service and representation HTC (my country) not know about this issue.

I send them to this topic XDA + this video on YT (not mine):

HTC should write whether it is software or hardware problem.

At yesterday's e-mail I do not have an answer.

[One (M7) Q&A, Help & Troubleshooting] Marco.t...:
I think we have to contact HTC's Headquarter / Development not the local once cause in my opinion they are not well informed and they have no technical background.

Almost everyone of us gets different answers. The issue is not known, software problem, hardware problem.......
[One (M7) Q&A, Help & Troubleshooting] Guich:
There is an article in an italian blog where they quoted an htc post.

This post said that HTC are knowing this problem and this will be solved via an OTA because is a software problem.

This problem is caused by the libs and the kernel, that the contrast and the color value isn't right.

All this info are by HTC Italia that send an e-mail to that Italian Blog.

So, if you won't trust me no prob, but i advise to wait for an update by HTC.

p.s. Riyal and Me are very busy atm and we can't try to solve the issue.

For who want the article, this is avaible here.

Peace & Love!

Edit:

Another info: all the people that have the issue, try to use zoe and see if the issue there is.

For all my friend that have tried this, they didn't have the issue!
[One (M7) Q&A, Help & Troubleshooting] UgXvibe:
I got excited for a minute. Put the phone face down in camera mode. Did the usual purple thing. Without moving the phone I went to Zoe and the screen went black!

Unfortunately, after a few minutes of playing with Zoe it started doing the same thing. Not as bad but still there. :(
[One (M7) Q&A, Help & Troubleshooting] chrisyng:
Zoes do not show the issue because they are actually taken in mp4 video mode, which means they do not increase the iso.. increasing the iso causes the sensor sensitivity to increase which causes the pink noise. If you are getting pink noise in zoe mode then your sensor is in worse shape then others.

There is so much misinformation in this thread now that it's getting silly...

If you think you are going to modify the kernel or other files to fix this issue, please learn how an image sensor works first.
[One (M7) Q&A, Help & Troubleshooting] Guich:
We know how to an image sensor works.

But all people can use zoe for the photo that they like without the purple noise ;)

And, as htc said, it's an issue caused by the contrast of the color in low light.

It's software, not hardware.
[One (M7) Q&A, Help & Troubleshooting] chrisyng:
If it is software, why do some people with the same software claim to no have the problem?
[One (M7) Q&A, Help & Troubleshooting] Guich:
HTC confirmed this.

With a software fix we can fix the prob.

Also some of my friend have this prob and other not.

A group of beta tester of some rom have this, and other not.

And, why the issue is born after the 4.2.2 update?

It's a libs/kernel issue, not an hardware issue, because a lot of people send the Phone to the htc's assistance an they received a phone with the same prob.
[One (M7) Q&A, Help & Troubleshooting] gerrya:
Purple stripes

Mine actually shows perfect black when I cover the lens, but in very low light I get purple stripes,like tiger stripes, mostly in one corner of the screen. Like others it must be heat because it does not do it all the time. It also appears that in low light if the subject matter is light in color its not there but darker colors bring it out more on mine.
[One (M7) Q&A, Help & Troubleshooting] chrisyng:
HTC has not confirmed this.. HTC has told people it is software and has told others it is hardware..

Getting the phone back with the same problem does not prove it is software, it could indicate the type of sensor they are using is flawed .

I have had this issue since 4.1.2 and have since been through 4.2.2 and 4.3 ..many people in this thread have the issue are still on 4.1.2 stock unrooted...

People have stated they received a repaired phone which went bad again after a few weeks.. if it is software, how does software go "bad" after a few weeks?

I guess there is no use in arguing, it will solve nothing. The only way I feel HTC will "fix" this via software is by sacrificing the ability to take low light photos.. that would be unacceptable. I was willing to buy a 4 megapixel camera for it's low light ability.. without the low light ability it become just a 4 megapixel camera in a world of other phones at 12+ megapixel..
[One (M7) Q&A, Help & Troubleshooting] bl4ckdr4gon:
Has anyone ever tried this?

Scene should be a dark area, with a single source or light(but not enough to light up the place)

When you click focus on the dark area, pink tink comes out. Well at least for me!

When you click focus on the light source, everything else is pitch black as it focuses on the light.
[One (M7) Q&A, Help & Troubleshooting] Guich:
I can do a good photo in low light.

And my phone is perfect...

Ah, my friend bought an one 5 days ago, no issue his phone, and this is manufacted in August...

So, i don't think is hardware.

And i trust at htc Italy.
[One (M7) Q&A, Help & Troubleshooting] chrisyng:
So by your logic, and what you have posted in this thread, you believe that you and your friend somehow managed to get HTC ones that have special "beta" software that allows your cameras to function correctly and that it has nothing to do with hardware.

[One (M7) Q&A, Help & Troubleshooting] Guich:
No.

I'm talking about the issue isn't hardware like a partition of a cracked camera by manufacter as someone said in this thread ;)

Because my phone was built in March, and i don't have the prob, other yes.

However, why this issue is shown up after the 4.2.2 release to a lot of people?

Before the update how many people have this issue?

I'm talking because a lot of people and htc Italy said that this is an software issue that can be solved via software update.

But, if for you i'm a noob, trust you, no prob :)

[One (M7) Q&A, Help & Troubleshooting] UgXvibe:
This pic was taken in the same spot but focus on the tv (light source). The blacks around the tv are perfect. I believe this is a software issue. If it was hardware you'd think there would be some kind of discoloration in the dark areas.
[One (M7) Q&A, Help & Troubleshooting] bl4ckdr4gon:
Exactly my point.
[One (M7) Q&A, Help & Troubleshooting] Ali812:
I feel like this is definitely a software issue despite many people being told by their local HTC centres that it's hardware. I took two pictures in the same position with the exact same lighting and got different results, all depending on where the focus was.

First picture:

http://i.imgur.com/wyI4PME.jpg

This picture shows the obvious red/purple tint that is well documented in low light situations as this one, in this picture I had the focus aimed towards the door in the middle of the photo, resulting in noise being drawn into the sensor as the focus was aimed at a source with almost no light being emitted (since the light from the photo is emitted from the surroundings of the door that is in focus).

Second picture:

http://i.imgur.com/4BjLU3G.jpg

This picture is much better quality in my opinion, it's not perfect as there is still some tint visible nor is it the quality I expect from a fully functional low light camera, but it's better than nothing. Same photo as the first one except I aimed the focus on the bag lying on the floor near the table, this caused the focus to be closer to a light-emitting source (the laptop) and reduce red/purple noise. Had I focused the camera on the laptop itself the exposure levels would have changed to just display the laptop's light itself and emit all other surroundings into complete pitch black (minus a bit of light coming from the side of the photo which is from my closet door that is not pictured in either of these photos).

All in all, my educated guess suggests that this problem is fixable via a firmware update without having to cap ISO or white balance, how long it takes or how HTC goes about fixing it is beyond our control but it's better than knowing that it's a hardware issue.

Hope this sheds light for some people.
[One (M7) Q&A, Help & Troubleshooting] ctiantolentino:
Yesterday I went to the HTC service center here in the Philippines and they said it is a hardware issue not software. I've also received an email from them today saying that the new components needed to repair the camera has been ordered from Taiwan already and will be arriving after 10 days before they fix my phone. It's fine with me to wait 10 days if indeed it is a hardware issue or not anyway the new 4.3 software update is only a few weeks away as well first for the US then for us with the International variants right after. Either way I'm just hoping for the best and this camera issue fixed asap. :)
[One (M7) Q&A, Help & Troubleshooting] bl4ckdr4gon:

Sure no probs will keep you guys posted. You can still bring yours to the only HTC service center in Makati even though you got yours from a different retail store as I did. Just bring your phone and the original receipt. You won't be needing to leave your phone with them right away as they will just get your contact details and the info of the phone and they will just contact you once the parts comes in. Go for it.
[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
It's not a matter of low light only but ISO levels,if you focused on the TV light the ISO is surely limited to max 200 while if you focus on a dark area the ISO will go up to 1600.

If ISO levels are making the purple tint it would mean either the camera module voltage is wrong or the white balance is crazy and needs calibration.

So again I say it's 50/50 chances it's hardware or software
[One (M7) Q&A, Help & Troubleshooting] slashas69:
Focus trick just reduces ISO check photo details and you will see it is avarage 200, compared with purple which should be around 1600-2000...
[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
I get purple at 600-800 ISO but of course the more you increase ISO the more you get purple.

[One (M7) Q&A, Help & Troubleshooting] Igor6661:
exactly what I have and many others, but Guich keeps telling it's software error. it's hardware and there is no doubt about it, not a second.

it's just the way sensor has damaged, some have all screen purple, some like we do, like something have melted...

and it didn't come after 4.2.2, many people have it on 4.1.2.

4.2.2 came just before heat wave in europe so maybe that accelerated the issue.

IMO software fix can only "camouflage" the issue, not fix it. or can make good unit not to brake, but once faulty, always faulty.

HTC quality control is equivalent to nameless cheap Chinese brands.

Can't believe I wasted months exchanging one after another. If it's not the gap, it's the camera, if not camera, it's the screen. What a joke.

Needless to say, I won't be buying another HTC device ever again. Won't recommend it to anyone.

I picked up a Verizon One yesterday and immediately noticed the purple tinting issue. I remembered that DPReview now has a mobile section so I went back to their HTC One review and was looking for areas where they call out the tinting. I came across the following at this point in the review http://connect.dpreview.com/post/8068966118/htc-one-camera-review?page=6

and further down in the conclusion

I know this more or less what we've been speculating but the fact that a very well respected camera review site is calling out the issue as being software is a bit comforting. This also confirms some people speculating that it's situation dependent as they have posted images where it was good and ones where it was bad in the same lighting. I think that even with a return the issue is still going to be present and if it's not it will eventually show up.

For the hell of it, I also decided to look into the purple issue that is known on the iPhone 5 to see if this is the same thing but DPReview put the kibash on that saying:

And I agree here, if you look at the flare on the iPhone versus what's happening with the One it's two different things.

[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
Nice find, but your interpretation is slightly off. What these posts are describing is a phenomenon that happens with specific HARDWARE ("wide angle lenses whose exit pupils are close to the sensor" - this is in fact exactly what we have in this phone). Their description is very clearly about hardware. As I have said before, this noise issue is in no way unique to this sensor, I've seen it elsewhere where I work, just not in phones before. Also as I have said before, this hardware problem can be fixed by software by 'ignoring' the noise. The noise will still be there, but it won't show up in our pictures. So it fixes it without addressing the underlying hardware issue.

As for people comparing pictures taken focusing on a light source, that tells you nothing about this issue. Focusing on a light source drops the exposure (both iso and shutter speed change) meaning obviously you won't get noise. What people are interpreting from these results is "hmm, it seems like the noise is inconsistent, sometimes it's there sometimes it's not, so that must mean it's a software problem because hardware can't be inconsistent like that." But that's completely wrong, if you took a thousand pictures focused on the light source they would all be ok, just like a thousand not focused on the light source would all have noise (assuming you could focus on the same spot perfectly every time ;))

OT, but yes, the IP5 flaring is different, that's the sapphire lens refracting strong light in such a way as to bring out the purple wavelengths, it has nothing to do with the sensor. Our problem is the sensor.
[One (M7) Q&A, Help & Troubleshooting] mariorenz:
I'm pretty sure it's a sw bug due to HDR persistence even after its deactivation (even with related voltage bug, if we want to see it from a techincal point of view). Indeed, I've have this problem only starting from 2-3 weeks ago and not before (I've to say it has operated in hot environments even in the previous weeks). Maybe the HDR activation gradually increases the problem even when deactivated and that could explain the fact in the first weeks I didn't face the problem. If my guess is correct, a sw correction will solve the problem, probably at 100%.

Similar problems here. I've had my Developer Edition One since early May and noticed this problem in early July but didn't think too much of it. It wasn't until my phone ruined a bunch of shots with a group of friends in a bar that I decided to look for a fix.

If I turn the camera on and set the camera face down on the couch I can see as the pink starts to fade in from the corners of the display. Sometimes it will flash between pink and blue. Zoe mode shows the same deal. A square grid pattern is visible in the noise. I can't be sure but I feel like the problem is worse when the phone is warm. Lastly, even with decent lighting conditions I get some blue tint along the top and especially bottom edge when taking portrait-oriented photographs.

Anyone out there with the Dev Edition have any success with a return/repair?

Attached photos taking with default settings, auto ISO (100 doesn't help much)

I've had a replacement a couple of weeks and just started getting this today just after dev unlock and flashing the GE ROM. I went back to stock to check it out and still there. Probably just coincidence, but pretty disappointed. It happens mostly in light conditions that arent good for most phone cameras but this is supposed to be good in low light so I feel ripped off.
[One (M7) Q&A, Help & Troubleshooting] Riyal:
Chill out guys... The real issue here is the white balance configuration of the camera. Some sensors were configured to have intense white balance leading to the pink tint issue.

To those who are debating if it's hardware of software issue then I say it is both.

It is hardware because the issue is not related to android OS nor kernel but within the camera module itself. But it is also software issue because the problem here is located in the hardcoded eFuse in the camera module which is unmodifyable once encoded.

But it should be fixable by recalibrating the white balance by overriding or balancing the efuse data in the module.

What is eFuse = eFuse is a type of independent firmware stored in a ROM on each microchip that's handling all the request sent by the OS to the module.

The issue is not directly related to the ISO. It's only triggered on high ISO because the device is programmed to scale up the white balance dark colors are detected by the sensor. To test this try adjusting your white balance to a fixed value and use the camera again in any ISO you want. You would notice that the issue is gone. But this still isn't a solution since adjusting your white balance to anything would make the picture look warmer or cooler than normal.

Yep white balance is responsible for tint in most situtations.

The One like the OneX before it,has a special chip for the camera,we can't modify it because protected by HTC codes but HTC techs can modify it as they want.

I think HTC found a way to get rid of the tint but they are trying it in any situation possible over weeks so they can be sure the fix is permanent.

At least I hope so :eek:
