[One (M7) Q&A, Help & Troubleshooting] jargalus:
yesterday i got my phone back from the service. 1st thing i have checked was the camera, of course. Perfect. NO blue, no pink just pure black. It is a joy to take pictures now. In the initial request i asked them to fix the gap from the speakers as well so now i was checking it and its, again, perfect. I have to admit that im very satisfied with the job that they did. Btw, camera lens are from 11.11 and they replaced the whole back cover of the phone not just the camera module.

Now the bad part. They gave the phone with 1 dead/stuck pixel in the middle of the screen. Im sure it wasnt there since before sending it to service i was running the screen test. Anyway ill give it 2 3 days to see if its really bothering me and if i can ill try to convince them to fully change the phone.

Im always amazed at how you guys can see one dead pixel out of 2 million. The one has more pixels than "retina" displays. And you guys can spot single ones. You guys must eat a lot of carrots.

On a serious note, if you can see it, it's probably not a pixel. Maybe dust. And I never understood the point of those pixel testing apps. If I can't see it then it isn't there as far as I'm concerned. Its as if youre actually LOOKING for something to be wrong. Are there apps to check your tvs too? How do you guys survive without a tv checker app?

Some pictures, cinesensor 2013/10/16

Serial no HT3B

Have the tint issue in low light in HDR mode.. Speakers are all right, the volume difference is a firmware issue. Build quality is almost perfect, the screen is slightly raised against the speakers, so you can feel it while swiping down. The camera sensor is slightly recessed into the back of the body, giving it more protection than before. Lock button recessed too (sadly), but otherwise it's OK. I think I have a dead pixel in the bottom right corner, but whatever. I'm done with repairing/replacing my phone..

I can ask for money any time, but for me HTC ONE is still the best. I've tried Note 3, LG G2, my wife owns Nexus 5 and so one. Still HTC ONE the best. So I'll keep exchanging until get the best one from HTC ONE.

HTC ONE set new high standards:

Front speakers

Low light performance

Best audio mics

Unibody

[One (M7) Q&A, Help & Troubleshooting] ac3kill:
That's crazy to hear the sharp sensor has the same pink issue . I was about to send mine back in till I read this above my camera is perfect pure blacks no tint just the occasional pink center in low light photos without flash if it's happening on your sharp sensor and my cinesensor 10-17 it has to be software

No biggie though only appears in certain lighting and I can always turn flash on to solve it on my phone so bot sending in for this unless it gets worse deff not going without my one for 2 weeks again

I'm happy with camera. I do get a flicker in color sometimes in low light but it rarely happens and think it had to do with certain kinds of light even then if I'm patient it corrects itself an I can get a wonderful picture def not sending this in for pink if sharp sensor has It also I'm thinking software on this problem maybe sensor calibration

[One (M7) Q&A, Help & Troubleshooting] alangrig:
The risk is only related with inappropriate repair. Changing only sensor doesn't resolve issue. All related camera parts should be replaced: cooling+shielding+camera module. That's what supposed to be I implemented. Mine H1's first sensor was produced in April and was issue free. Pink tint only appeared in Full HD HDR. Service center change twice camera module. Both modules were from Sharp and latest ones, but problem was not resolved. So the conclusion is obvious.

Finally, I rejected any further repair and replaced H1 for a new unit made in November 2013. Yes, new unit has incorporated camera module from Sharp, but still black areas in Full HD HDR in low light resulted in pink and red tint.

Claim all related part to be replaced.

Yes I am fully aware and have tested more than those scenarios. It seems like we have a oversaturated device in our hands. I noticed in the other HTC One the pictures were yellowish(warm) and colors are not as bright as ours.

I'm also in that situation. I purchased the device from Europe and I live in asia imagine the hassle I would need to get it fixed/replaced.

[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
After reading the posts here and trying more things on my phone, I'm 90% sure it's just an ISO utilization issue. Look at all the posts confirming that the red is in pictures taken higher than ISO1600. To confirm I manually set the ISO to each of the settings 100,200,400,800,1600 and repeated my tests. The red didn't show up until 1600 even when completely dark as before.

This could be easily fixed by an update.
[One (M7) Q&A, Help & Troubleshooting] VictorC:
[MENTION=5223921]Xerro-Five[/MENTION] [MENTION=4386647]Riyal[/MENTION]

I tend to agree with this, somehow... but It doesn't explain why some shots appear red and others don't, using the same ISO.

For example - the pictures below... They're both shot in the same lightning condition and both on full auto ->

- fist image, ISO 2000 and red all over because I steadied for the shot,

- the second shot - full auto and ISO 2000, but taken in the first 3-4 seconds, right after the focus was set... If i had waited longer, the redness would have set in...
[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
I can't say if this is the sole reason or not, but I've noticed that situation too which I attributed to the sensor trying desperately to collect more light. Meaning that initially the effect is minimal because it hasn't had a chance to build up noise yet, but then the high ISO combined with the longer exposure times would later lead to noise. Trouble is I'm not sure how to test that to prove or disprove it... All I could do was observe that increasing the exposure time worsened the effect and lowering it helped. But I can only lower it to -2 which was not enough to stop the red.

This could also be a unique issue of "ultrapixels" I don't remember off hand how the dimensions of these pixels compare to a dslr sensor etc... But you know, new tech and all :confused:

---------- Post added at 02:28 PM ---------- Previous post was at 02:24 PM ----------

The one thing we know for sure is that the color is noise. Which is why I still believe it's just an optimization issue that can be resolved by update.
[One (M7) Q&A, Help & Troubleshooting] VictorC:
I took some time tonight and shot some comparisons pictures with the One and my old One X and the results made me relax a little about the quality of the camera in low and very (I mean very !) low light.

It may be just an ISO setting error that could be fixed with an update and not necessarily mean that the camera sensor is faulty like [MENTION=5223921]Xerro-Five[/MENTION] said.

But... Still, i just cannot manage to capture a photo with a perfect (or near perfect) black as the ones in some tech reviews (EX: Anandtech's review of the One) . There is some difference in colors between auto mode and night shot (See below)

Compared to my old One X - it obliterates it in very low light. It just captures more light and more detail, admittedly turning more dark stuff into blueish noise. But see for yourself...

->>> For this picture there was an orange light post a bit far away from my position and a faint green neon on one building closer... The sky was reddish from the city lights...

And now some One to One (X) shots :)
[One (M7) Q&A, Help & Troubleshooting] Ardmanz:
I have the same issue but not all the time and it's difficult to recreate.

What I did notice is that I can see it on the phone before I take the shot (it doesn't look normal then I take the pic and it's weird). I will do some more testing on mine and report back.

Mine still has the 1.28 firmware btw.
[One (M7) Q&A, Help & Troubleshooting] VictorC:
[MENTION=4323911]Ardmanz[/MENTION] Please do some testing if you can :) We are all here (I think) on the 1.29 ...

[MENTION=5235636]VictorCozmei[/MENTION]

But if this is a software issue others should have the same results as we have the same hardware. Or probably HTC One is using different sensors? But I dig it already up to the kernel level and all I can see is the ST VD8689 sensor driver.

Good news! Been messing with tweaking the sensor drivers since yesterday and look at the results! :good:

Took it from my device just now and covered the camera with my hand :D

Check the exif info :laugh:

Still not perfect yet though but we're close!

Any professional photographer there good in playing with BGR gain values?

I am not good with these apparently all my adjustments so far are a fail.

1st attempt = grey with a little pink and full of white powdery noise.

2nd attempt = full grey and full of white powdery noise.

3rd attempt = almost perfect bat very2x dark!

I need to balance the red and blue gains but still maintain the white balance.

Please note I am tweaking the sensor driver directly in the kernel. So for this fix to work you need to flash a custom kernel.
[One (M7) Q&A, Help & Troubleshooting] Riyal:
Another update guys! I already resolved the dark issue problem now is when taking pictures in daylight it's somehow greenish now :(

I really need someone with knowledge about this as I'm just blindly inputting random values.

Anyway I'm off from now and back to my previous kernel... Gonna get back on this some other time.
[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
I admire your determination, I really do :thumbup:

However I would save yourself the headache for now and at least wait it out for this week as there's been a lot of talk of a 4.2.18 update hitting our phones shortly. It's my understanding that some in EU already have it. There's a pretty solid chance they tweaked the calibration so it may fix the issue.

Also adjusting the gain is a losing battle for this IMO because gain, unlike hue or saturation changes the other colors as well (as you saw with the inadvertent shift to green by dropping the red - that's exactly what you would expect to happen). If you dropped blue it would turn yellow and so on. Also since it's noise, the gain won't solve the real underlying issue.

Hopefully you're correct. But the issue is in our sensors and not thru software. If HTC calibrates the software other users without this issue would be affected.

But since this can be fixed by software hopefully they can workaround the issue. But recieving a negative response from them about this issue I am assuming they haven't recieve any reports yet and am really doubtful this will be fixed on the next update. And like I said I already tried the 4.2.2 update that was leaked and it was not fixed yet.

S4 of my friend cant take a shot like my second pictures.. Try and retry more time.. I'm confused because, with only ( low) Light from candle, there aren't purple/red issues..
[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
Interesting, I'm not sure why the s4 couldn't do that, I've taken similar pictures with my old iPhone and I've seen similar pictures taken with the s4 in reviewers articles. Perhaps I don't have a good sense for the lighting conditions in the room aside from the candle.

But a candle is not a low light scenario when you focus on it, it's a light source after all. If you focus on the light source, the camera will auto adjust the exposure settings to best suit your point of interest and more or less ignore the rest if it's functioning normally. That's why the candle is overexposed in the first picture and the background is underexposed in the second. This means the iso will be lowered (should be at least) because you need lower iso for bright objects, and as we have all seen in this forum lowering iso prevents the color issue because there is no noise.

[One (M7) Q&A, Help & Troubleshooting] chrisyng:
After much testing with my phone, I've come to the conclusion that the cause of my pink noise issue is the sensor overheating.

If I don't use the camera and let the phone come to idle temperature, the moment I launch the camera app in low light situations, I can get terrific shots.. but after a few minutes, the pictures get hazy and the blue/red noise start to take over... If you exit the camera app and allow the sensor to cool, then open up the app again, the noise disappears until the phone starts to heat up again...

There are some extra factors that cause the phone to heat up quickly effecting quality. The camera app put the screen at 100% brightness... This causes the phones temperature to raise quickly allowing for the sensor to heat up quicker.

I also have a adhesive protector covering the back of my phone + have the phone in a poetic athmosphere case.... These 2 items act like an insulator and lowers the phones ability to shed excess heat quickly..

Perhaps this is why people who have sent their phone off for repair have been reporting that the cameras worked for a bit, but then went back the pink screens after.
