[One (M7) Q&A, Help & Troubleshooting] akpe:
AFAIK warranty is covered by manufacturing date.

As for the green tint issue, on a previous discussion with HTC Greece they told me it's a software issue which was supposed to be fixed with the Sense 6 update, and specifically, the (then) new firmware. If you updated to Sense 6/4.4.2 or Sense 6/5.0.1 and green tint is still there, then it's caused by something else.

Good thing is that they seem to be aware of the problem, at least HTC, don't know about their service. Just take a few camera shots for them describing it and you should be good to go. Either they will fix it for you, or replace your device.
[One (M7) Q&A, Help & Troubleshooting] renevp2:
Yep, I really was hoping it would get fixed with the Sense 6/Android Lollipop 5.0.2 update a few weeks ago, but it unfortunately didn't. I'm even about to print some examples for them (hah), pictures look horrendous in some occasions.

And yes, I'm glad to know my warranty doesn't run out until June. (figured out my manufacturing date over chahtc.com )

[One (M7) Q&A, Help & Troubleshooting] cyrusct82:
Don't know. But that I was thinking too.

Some says that the OIS is separated from camera. But technically I don't see how because is one module. I don't see another module in front of camera.

[One (M7) Q&A, Help & Troubleshooting] gustav30:
OIS was not removed. I own both an M8 and an M7 that had its sensor replaced with the OV model last year due to purple tint. Trust me, when I take pics with the M7 it is very stable in my hand, as opposed to M8 with same sensor. Especially video recording.

I believe the OIS is a physical chamber the sensor sits in, as opposed to EIS which is built into the sensor itself.

hi, i recently bought a new camera module from aliexpress for my m7 because of the purple pictures.

I got this model from the shop: (there are 2 codes on the camera)

13p1bs402

m:442b1.0 (or m1442b1.0 not sure if it's a "1" or a ":" )

However, this one didn't work at all! The phone didn't recognize it.

(I have a htc one m7 801N)

So, i ordered one from a different aliexpress shop, which had this numbers:

13p1bs402

y1425b1.0

This ones worked! No purple screen..So, even it says 13p1bs402, it is not a guarantee it will work!

I think maybe your model number (801N etc) has something to do with it..or the camera i received was broken, that could also be the case of course.)

Btw, i have Lollipop with ViperOne 8.0

Have you tried your new camera with Android, different from Lollipop?

[One (M7) Q&A, Help & Troubleshooting] solefero69:
To make the point of the situation : there are 2 kind of problem

1) If you cover your camera sensor it stays black until he saw a source of light, then the purple noise come out.

2)If you cover you camera sensor you can immediately see purple noise even if isn't exposed to any light.

I think that the one is software and the second it's hardware. What do you think about guys?
[One (M7) Q&A, Help & Troubleshooting] chrisyng:
In my opinion they are both hardware.. the first situation would have gone red eventually once the sensor warmed up.. the second situation, the sensor is already warmed up and will show red right away..

If have you root, could you please share you cam libs with us so someone can try them and see if is a software problem?
[One (M7) Q&A, Help & Troubleshooting] ingenious247:
Ok so I did some testing and this is my hypothesis. Our camera's low light sensors are very aggressive - in the absence of light the sensor adjusts to a different color spectrum based on the amount of light it senses.

If their is a minor absence of visible light, it will choose violet because that is at the top of the visible spectrum and allows the shortest wavelengths to be captured. However if the available light source is too low for this wavelength the camera will not "see" images clearly. Then it will choose blue, which supports the 2nd shortest wavelength in low light. If the sensor detects compete darkness (such as setting your phone screen up with the camera facing down blocking all available light), it will choose red because that color is at the very bottom of the visible spectrum and allows the longest wavelengths of light. This is why you will see a shade of pink to bright red as the sensor adjusts to complete darkness. (This is why red is used for "night mode" in various apps)

I conducted multiple tests in various low light settings to confirm my suspicions. I then researched on the internet to make sure I was correct in my assumption with regard to the light spectrum. Link is below.

I don't think we have defective cameras. We have really sensitive sensors. In some extreme cases I'm sure the sensor might be defective, but for the most part this is probably how ultrapixel cameras function and are able to capture better low light photos.

http://science-edu.larc.nasa.gov/EDDOCS/Wavelengths_for_Colors.html

---------- Post added at 07:55 PM ---------- Previous post was at 07:13 PM ----------

Oh and btw heat is very closely related to the red spectrum of light and yes I do believe it will emit enough wavelengths in that spectrum to activate the sensor and make it switch to red. Another hypothesis yes but warranted imo.

*Update - you can perform a simple version of my test with your own palm.

Stand in a room with fairly bright artificial light (from light bulbs for best effect, old school or new low energy bulbs) and bring the palm of your hand close to the camera, about 2-1/2 inches away, and hold it there. The image will develop a violet tint within one to three seconds, progressing to blue, and as you bring your hand all the way in, pink to red within another few seconds.

*edits for various Swype-o's and corrections.

Hmm that doesn't look like the aviary I'm using at all... I'm at a loss as to what's going on here. Would you like me to try and get you the apk for the one I use?
[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
Yes I agree with you pretty much 100% on this, good researching :) it seems to me as well that the sensors are just very sensitive (which is also part of the reason the low light performance is so much better than others), there's no way IMO that so many sensors in so many batches would all be "malfunctioning" per se. They're just not behaving as we expect.

I can now also confirm that temperature is a huge factor in this issue (for my phone it seems to be the only factor) thanks to a brilliant suggestion by [MENTION=2135799]evilmastr[/MENTION]

I have a cold room at work so I did some testing. I pre-chilled the phone to 5 degrees C in the room and then started taking pictures. Temperatures are reported by GSam for the battery.

1. Flat on table, 5 degrees, no noise present

2. Flat on table, 9 degrees, 1 min camera and screen on, still no noise (looks exactly the same)

3. I continued to leave the camera and phone on for 5 min. The temperature stayed at 9 degrees and there was no noise.

4. Take a low light picture while still in the room. No noise (the red color is because of the lighting and white balance). Sorry it's not in focus...

5. Put flat on table outside the cold room, 9 degrees, again no noise.

6. Wait for phone to heat up to normal, 29 degrees, 10min later put flat on table, NOISE!

7. Return to cold room to take the same low light picture, 29 degrees, typical blue noise.

So it's pretty clear to me that heat is causing the issue, which also clearly means this issue is hardware in such cases. Too bad "heat" for this sensor is normal operating temperature... :sly:

Anyway, I'm still satisfied with just fixing the pictures after, quick and easy :) I don't think I'll be trying to get a new phone.
[One (M7) Q&A, Help & Troubleshooting] evilmastr:

[One (M7) Q&A, Help & Troubleshooting] chrisyng:
The reason some phones seem less sensitive to the heat is because there is no way to accurately measure heat of the image sensor... Everyones phone use is different.. and some people may have apps running in the background that could keep the phone at higher temps due to an awake cpu and not even know it..

The fact is as I have stated from the beginning.. the sensor gets pink noise due to heat.. everyone's sensor will do this.. at the light levels the camera starts to go pink if you back down the iso levels you can get cleaner images at the expense of the darkness of your images... However even if you back down to 100 iso to get rid of the noise at a particular light level, your image will not be as dark as images that come off a different phone without an UltraPixel sensor..

Are our phones broken? No... Are our sensors broken? No... Are the sensors flawed? Yes.... When the sensor is cool, it can take a very good low light picture at 2000iso .. when the sensor is hot, 2000 iso is very noisy and pink.. that is a flaw that we all have to live with... A flaw some people may never encounter because of their specific use of their camera phone

[One (M7) Q&A, Help & Troubleshooting] Bravoexo:
I would just lock the AE/AF if I'm taking a pic of something pretty dark...dark enough to trigger the sensor to go up to ISO 2000 if I left it on AutoISO. But then agian, I do not think there's any real need to take a pic of something that dark in the first place...

HTC should tame the Auto Exposure via software that it detects the read/blue wavelength too often...and brings it back down to a reasonable expectation of exposure that it doesn't flare all over with purple tint...
[One (M7) Q&A, Help & Troubleshooting] evilmastr:
I didn't know how to lock Auto exposure/focus. So if anyone wonders, here's how you do it! :) Long press where you want to lock the exposure and focus. Simple as that, lol.

T9'd from the darkest M7.
[One (M7) Q&A, Help & Troubleshooting] Bravoexo:
Right, normally if I want to take a pic of a dimly lit room, I lock the exposure to the brightest spot in the scene, or take a lock of exposure from a bright light source first, then point it back to the composition of the pic that you'd want. if the highlights are enough around the pic, then you'd avoid the problem, and still get a pic with enough highlights ...

Unfortunately, focus is also locked, so hopefully you lock the exposure at a light source almost at the distance of the final composition of the pic ... with enough of those with highlights come into focus.

HTC should allow AE lock, AF lock and Metering available as touch options in the next software update... wishful thinking.
[One (M7) Q&A, Help & Troubleshooting] evilmastr:

smart, it certainly made a difference, another observation when not in video , flash almost or fully eliminates the clouds, locking the AE results in out of focus everything else tho, as for the finger test well i don't think anyone wants to do that unless for testing purpose still the issue is there :(
