Do you also experience the same issue as ours? I believe it's a miscalibration. Or probably an issue with image sense chipset of HTC. Did any of you guys already tried directly ask HTC about this issue?

Anyways could I ask you guys the build number of your phones?

[MENTION=5235636]VictorCozmei[/MENTION]

Considering that this phone should boast low light capabilities I think this is not a normal behavior. What we should do is ask directly HTC if this is solved through software or hardware. As far as I know not all people here experience this issue else we could seen alot more posts about this.
[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
Well yeah, that's what I was getting at lol. Even right now for example it's dark and the blacks can turn blue and/or red. Again I don't think this is a problem but rather a normal behavior of image sensors (at least in my experience) so I haven't made any complaints or inquiries.

Some users doesn't have that annoying red/blue tint on their devices even when covered.

Here's mine

And here's from another user
[One (M7) Q&A, Help & Troubleshooting] VictorC:
[MENTION=4386647]Riyal[/MENTION]

Mine doesn't get red when i cover the camera with my hand and take a picture (or if i put it on the table with the camera down). Its black, but at night time and in extremely very low light it goes to red... If it finds a little more light than the black areas get blue, blueish or purple... And it gets very hard to focus for a proper shot, even if i point it towards a light source like a lamp post.

I took a photo with my hand fully covering the camera and it turned out black. I compared it to the one posted on the other thread by the other user, the one who uploaded his black photo for you so you could see the exif data.

Compared, mine was taken with ISO 400, the other user's photo was ISO 2000 ... Mine had thew birghtness -2.163531, his was -4.48546

What does yours say?
[One (M7) Q&A, Help & Troubleshooting] Riyal:
Mine is also saying 2000 ISO and brightness(based on properties detail on windows 7) 4.28472

This only mean 1 thing... Our phone's sensor is either uncalibrated or is just way too aggressive in collecting light.

I can only recreate a pitch black result by covering the camera if my I manually set my ISO to 400 or 200. Setting it to 800, 1600 or Auto shows up the reddish tint.

I already contacted HTC about this and sent a sample screenshot. Now let's see what they can tell.

[MENTION=883405]Professional[/MENTION] photographers

What do you think this is? color temperature issue? Gain issue? I can modify these values in the kernel if someone can confirm me what might be the real issue is.
[One (M7) Q&A, Help & Troubleshooting] VictorC:
[MENTION=4386647]Riyal[/MENTION]

I tried again to take some shots with my hand closely covering the camera.... One picture was purple, the other one was red... In both ISO was 2000...

-4.4 in brightness
[One (M7) Q&A, Help & Troubleshooting] Riyal:
Well I guess all I could say is.... Welcome to the club! lol! Now with so many users having this issue I don't know if it's indeed an issue or not. Is this the downside of having 300% more light in a low pixel resolution camera?

---------- Post added at 04:36 PM ---------- Previous post was at 04:26 PM ----------

By the way I'm gonna go to our local telecom provider later since they have display units of HTC One here. I'll take a look and see if it also has the issue. Last time I checked it was a May build so it's a new batch.

*Hope it gets the same result to ease my mind*

I'm really gonna fret out if it's a hardware issue as I have to ship the device back to europe from asia just to get it fixed/replaced >.<
[One (M7) Q&A, Help & Troubleshooting] VictorC:
I'm looking at the anandtech review and I don't see this problem in their night shots... For example, this picture ( http://images.anandtech.com/reviews/gadgets/HTC/HTCOne/cameracomp/bench-HTC One.jpg ) was taken on full auto and it returned an ISO of 531 1/15s and all that was supposed to be black was black...

If I try something like that... I'll most certainly get an 1/7s and an ISO-2000... :(
[One (M7) Q&A, Help & Troubleshooting] Riyal:
I don't think so... Look at the light in the area it's way to evenly spread out for yours to become reddish believe me I have tried it. For the photo to become reddish you basically need to have a very limited light source(candle in a completely dark room) for the sides to become reddish.
[One (M7) Q&A, Help & Troubleshooting] Floris2310:
+1 on the above stated issues. When I cover the lens, the image turns red because iso shoots up. However when I manually set the iso lower (say 100), then the image is just plain black.

I honestly do not think this is a defect of some kind but rather normal behaviour with high iso settings. But when someone can take a pitch black picture with the lens covered on iso 2000 than we will have a problem ;)
[One (M7) Q&A, Help & Troubleshooting] VictorC:
I've tried taking photos in similar scenarios like the one on the anadtech site and my result was a photo with blue and purple-ish noise instead of the black that appears in their photos. All on auto on my device -> ISO 2000, 1/7s, blue instead of black areas
[One (M7) Q&A, Help & Troubleshooting] Riyal:
I was thinking the same as you before someone gave me this pitch black result.

I'm pretty sure I could get exactly the same results with my phone. Even just a single street light is enough to remove the reddish tint on the camera. However what I find odd is flourescent lights can't remove it.

Confirmed! We have a weird sensor on our devices. I manage to play with another HTC One in a store here in our place and it's indeed having perfect pitch black images :(
[One (M7) Q&A, Help & Troubleshooting] Floris2310:
damn, bad news then. Probably a stupid question but did you check the ISO settings on the device?

There are two possible scenarios here:

1) We have a sensor which is acting weird/broken

2) There is something wrong with the ISO selection and it typically takes an ISO to high which causes the red image

I think (read: hope) the second option is more likely and the good news is that this would probably be a software rather than hardware issue.

Anyway, thanks [MENTION=4386647]Riyal[/MENTION] for checking this!
[One (M7) Q&A, Help & Troubleshooting] VictorC:
[MENTION=4386647]Riyal[/MENTION]

This is horrible :crying: @#$%!

If this is truly confirmed and there are a number of One's out there with broken sensors, than I think this thread should be renamed so that all users know about this problem. Maybe some of them, looking to buy the One, can do the camera test before purchasing a faulty unit!

I just got my One and I'm falling in love with it and now I have to take it back and be without it... :rolleyes: More over, the great HTC-partner service we have here doesn't not know the meaning of the word "replacement" and they will most surely try to open and fix it (oh the horror!!) ...
[One (M7) Q&A, Help & Troubleshooting] Floris2310:
I would wait a little longer before returning the device. The 4.2.2 update is just around the corner and I have read somewhere that there are some camera improvements. Perhaps the issue is fixed with the update. If it's a software problem that is.

Waiting for comparison after update to 4.2.2.

Also, what I have noticed is that on the top photo (faulty one) that device on the wall (AC or whatever it is) has that bright blue light.

Looks like it may be the case that the camera tried to tune to it resulting in making everything blue. The comparison photo has that light red.
[One (M7) Q&A, Help & Troubleshooting] buzz33:
That blue/red light is ok, that is setup box from ip tv and on first picture is turned on (blue) and on another one is turned off (red) :)

---------- Post added at 01:22 PM ---------- Previous post was at 01:09 PM ----------

And yes, I upgraded android to 4.2.2 and everything seems to be fine... Camera is working flawlessly, even it have more features now, like AE and AF lock....

Interesting, booth devices was built in May.
[One (M7) Q&A, Help & Troubleshooting] Ciebiada:
I wasn't indicating that the camera made that red light appear blue, quite opposite. I think that blue light may be partially the reason the dark area was rendered blue :). Anyway, good to hear that 4.2.2 update didn't break anything for you.

To contribute to the thread I may add that I definitely didn't notice anything suspicious regarding camera at 4.1, even after upgrade to 4.2. Now after reading threads like this one, I have noticed that when trying to shoot in a very, very dark room with no light source the image is getting more red and red like it tried to do something but it couldn't.

In my opinion this is how the camera software works, apparently HTC made big effort to make the camera do wonders in low light condititions, and what we are seeing is exactly that. Probably some of the sensors are worse than others at capturing enough light and the software is making it red/blue.

[One (M7) Q&A, Help & Troubleshooting] sallam5010:
SO I was comparing my HTC one with my friends last night ! When I noticed my other friends HTC one low light shots are really bad ! So I took both phones put it on their camera faces down completely dark place ! And here's the results both on 4.2.2 but the red pinky pic token from device got the latest OTA which ends with .2 and it's serial number is HT367XXXXXX.. the other pure black is my device 4.2.2 also but ends with .1 and it's serial number is FA33XXXXXXX..

I believe that would be bad calibration for dark spots in low light maybe ?

Just thought I'd share this with all. I bought a new HTC One on September 20th. Had a bad phone with the defective camera.

[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
A fix can't come with a simple rom update,or else any third party app could work without purple issue.

You have to flash the FW(bootloader and co) as well because only this can update the eprom of the camera chip.

The One and One X have special chip for the camera,if the fault is really software wise,and as we saw 3rd app camera apps have also purple issues then we can conclude the problem is with a bug in the camera chip itself.

A reprogramming of the eprom should help then and it needs a deep flash situation like a bootloader flashing process.

So in conclusion don't expect any change with a simple rom flashing

I would be cautious with that LG G2. I am not going to lie, the screen, the thin bezel, specs, all looks sweet, but on the other hand you can clearly see they took Samsung's approach on it. Which is to max the specs and put features packed hideous software in it.

I wouldn't even consider it unless I was sure it will run AOSP flawlessly. HTC tricked us here and there with the One (boom sound, camera, gapless design) but it is still quite well thought phone, and as a bonus you have a choice between AOSP and Sense, which for the first time doesn't look like a software crafted by kids in the garage.
[One (M7) Q&A, Help & Troubleshooting] opher50:
Exactly... That's the worst mistake HTC could make.

First Telling everyone that they would fix the camera problem with the next update, and now after taiwani's report it didn't help they silently remove the camera fix from the list.

I can tell you further than that, I dont know what have they done but it became worse.. Before the update with ISO 100/200 and even 400 it would look pretty fine I guess, Now? iso 200 is purple like a diamond.

Strangely enough, the 3.18 update did fix my tinting problem (running on a brand new HTC One Red FA38, with fw 2.24, so the "fix" was in kernel and not in fw).

It completely eradicating the "camera on desk" test problem in which before the update after 5 seconds the screen would flood with red-purplish static, now it just remains black even after 3 minutes. It also hugely impoved low-light performance.

All shots on auto

I know that these are not direct comparisons, but trust me when I say that the lighting conditions are more or less the same (or in advance for the "before" pics, as they were taken on a clean full moon night, whereas the "after" were taken on a dark, cloudy night). Again, as the images can be deceiving, these are all taken on really poor lighting, despite the fact that they seem to be taken on a well-lit street, as One's camera captures a lot of light (actually, when I took these pictures I could see a lot more on the viewfinder than my my bare eyes)

And as a last note, HTC did not lock the iso, like many were speculating. The pictures taken after the update were shot on auto and the iso was automatically set to 2000.
