[One (M7) Q&A, Help & Troubleshooting] ac3kill:
I believe they are talking about about the 3.17 firmware HTC killed the low light photo ablility in the firmware to try and stop the purple blue and red tint. I currently have the issue and the new firmware does make it better but kills the low light and mine already doesnt focus like it should.

I can open camera up and see at night time for a split second before their patch kicks in and it goes all black removing the blue. That spilit second of being able to see is how the low light photo should be but because their is so much blue static it turns it all black to where you can't see anything without flash. Where as you should be able to take a low light photo without flash and it come out good. Unless the update is a miracle and 3.17 4.3 is just a test base and no where near the final

We will all need to send our phones in for new camera.

I have been calling HTC and att almost daily to work something out. They all just tell me wait for the update then send it in. And I wanna be like I already have the update android 4.3 and my camera is still crap but can't because it's not officialy out and we don't know if that's the final one or not. I take it that's why this thread has died recently. Everyone is waiting for the update. I think we are all gonna have to send out phones in though
[One (M7) Q&A, Help & Troubleshooting] Florin82:
Well, it is only normal everybody is waiting to see what the update brings since it is the only official and non-service implying variant. I think most people here will settle for purple free pictures even if we lose the night time advantage instead of having to go to the service - which is a nightmare in some places. Anyway it has become clear that this first generation Ultrapixel tech is a bit of a fail probably due to poor quality of production of the camera module - there have also been lots of people complaining about daytime pictures (blurriness, lack of focus...). Guess HTC didn't manage to correct this situation which i am sure they knew existed from the very beggining but it was too late to change anything. Anyway, i'm still keeping this phone since i consider it to be great even f it is a bit of a fail in the camera department - new ideas like these come with a certain risk. For some lucky one's it payed off if they got a good camera module.
[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
The final update of 4.3 should roll this week.

Let's hope the fix is included or at least they clearly say officially that a definitive fix will come and will be the ETA.

limiting the iso to 200 is not gonna fix it as after a while even at 100 the purple begins specially on the borders

[One (M7) Q&A, Help & Troubleshooting] slashas69:
Tried and 101 time we repeat it is not related to the camera app...
[One (M7) Q&A, Help & Troubleshooting] dagrim1:
Depends on what you expect. Getting good low-light shots for me means I can actually shoot pics when there is little light. At first the camera was making things way to bright for my liking (and introducing the blue/purple/red tints at the same time) and now, when the image is darker, it actually reflects reality better in my opinion. The brightness was partially accomplished by increasing ISO to 1600 or 2000 or somethign... which I would hardly ever want as it produces a lot of noise at the same time.

I'm not expecting to be able to shoot things I can't even see with my own eyes, I expect I can shoot a realistic picture in a darker environment and that's what I was expecting from this Ultrapixel stuff. Making the pixels larger, allowing more light to enter, reducing the need of extremely high ISO (and as a result noise) or long shutter times (and as a result movement blur).

I now see I can shoot pictures with ISO 400, and a shutter time of 1/10th of a second which can actually come out pretty decent. And that's all I would expect from a phone.

By the way, I also own(ed) a Lumia920 so I am actually pretty spoiled by the it's camera which takes excellent low light images.

[One (M7) Q&A, Help & Troubleshooting] the_eclectic1:
You are right. Sadly G2 & S4 too plasticky. But Z1 is like Nexus 4 with glass back. Possibility of breaking glass doubled in front & back. Also finger print magnet on the back. Aluminium has its drawbacks too. It's easily dented/scratched.

Perhaps titanium would be nice! Stronger than steel yet lighter. But expensive! Tough material choices for a designer.

How to set the shutter speed on the camera HTC One?
[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
From my more then 10 years experience with phones and smartphones,the best material is rubber,I think the SE K800's back was made of a soft rubber.

It's better looking than ordinary plastic.

It's better in hand feeling and give excellent grip.

Can't scratch permanently (just rub with your finger it and it goes),can't dent,brake nor chip!

[One (M7) Q&A, Help & Troubleshooting] Ali812:
I switched from ViperOne 2.6.0 to ARHD 21.0 (full wipe before flashing). Since ARHD 21.0 is based off of the leaked AT&T firmware it includes HTC's software "fix" that they have been talking about. As long as you switch to a ROM with base 3.17 (like InsertCoin I believe) you SHOULD get this "fix" but keep in mind that it hasn't heavily improved for everyone who has tried.
[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
You don't have to update the Bootloader to 3.17 before using a 3.17 rom?
[One (M7) Q&A, Help & Troubleshooting] Ali812:
Have you tried the new firmware yet yourself? I was skeptical on the low light performance but it's still very impressive. Take a picture through the new firmware and take the same picture with another phone like an iPhone or Galaxy S4, the low light performance is still VERY good in the new firmware when compared to other phones (I'm not sure how it was before since I constantly had the purple tint when trying to take low-light photos), so no this fix does not kill the low-light ability of the phone, at least not for my experience.

That being said the software fix could use some more tinkering to make it better, it's a step in the right direction but if this is their final fix I will be heavily disappointed considering how long everyone has been waiting for the OTA update.

Where did you read that ISO will be locked to something as ridiculously low as 200? 200 limits A LOT of light, it would make any phone camera useless. Also if you're getting purple on even something as low as 100 ISO (it's practically nothing, try taking a low light picture with 100 ISO you won't be able to see anything) then your camera is definitely damaged, before using 3.17 firmware I would have all black when the camera was on a flat surface for up to 400 ISO.

I don't think this fix contains a software fix that locks the ISO to a certain value but better calibrates what ISO to use in low-light. My results vary in ISO depending on the photo I take. I get ISO as high as 2000 with no tint and as low as 400 depending on the picture. Wait till the update or try out the leak, if it's not a viable fix then send your phone in for repair because from what you're saying your camera is in worse condition than most people here (except for the purple wave club).

I didn't need to update the bootloader. I simply flashed the ROM and it did the trick.

I'm still S-ON, I've been able to update to newer firmware ROMs with no issues despite people saying I need to be S-OFF (I tried S-OFF using revone and it said it was successful but bootloader still said it was S-ON).
[One (M7) Q&A, Help & Troubleshooting] the_eclectic1:
I had the SE K800 before. Great camera for its time.

Pros:

Rubber has excellent in hand feel. Chip/scratch resistant.

Cons:

Susceptibility to degradation. Depending on how long you plan to keep the device and where you live, rubber degrades over time, more so in a hot climate. I live in the tropics and the rubberised material will eventually turn sticky/gooey. :(

I've been using HTC devices since 2004 during the time of WM2002 and 2003 up to now. I like how HTCs are designed, how they can do things that other phones cant, and I like even Sense better than others. But if this camera issue doesnt get fixed, I might just start looking for another brand for my next phone.

[One (M7) Q&A, Help & Troubleshooting] the_eclectic1:
I know what you mean. HTC designs were nice, and they were always innovating. My first HTC was the Hero and since 4 years ago till now I owned 9 HTC phones plus a few others. But the One has been very poor with quality control issues with the gaps, now the camera. I still like this design esp with Boomsound. But I think even now there are still gap issues on some of the Ones, 5 months after launch! For a premium product it's a big fail. I was looking forward to the One Max, but now? I'm not so sure.

I updated the phone firmware from 1.29 to 3.17 this weekend and moved to the new ARHD 21 and I see no improvement in the camera on my phone. Pictures are still consistently purple in any less than optimal lighting situation. I'm not confident this 3.17 is the "fix" that HTC intends to release.
[One (M7) Q&A, Help & Troubleshooting] JBernardo10:
I smell a hardware issue... I got the phone last week and it has this problem as well! I'm afraid of replacing it though since all the phones on my carrier might be of the same batch... I'm just wondering, is it possible to correct this issue by color correcting the photo afterwards? This has nothing to do with this phone but in the Battlefield 3 game there was a way to "remove" the blue tint the game has by color correcting every frame before displaying it to the screen. Don't know if this could be a solution in the htc one though...
[One (M7) Q&A, Help & Troubleshooting] UgXvibe:
I have had a little success using Photo Editor by dev.Mcgyver in the Play Store. You lose a little detail in the pic but using the Color Levels adjustment you can lower the red and blue a little to lessen the purple a bit, also lowered the overall Hue a bit. I'd rather have the phone make these correction and then some...

[One (M7) Q&A, Help & Troubleshooting] Unklejoe:
I was thinking, maybe this could be fixed by a black calibration. Basically, you take an image with the sensor completely covered and record the image. You then apply a correction until you get an equal value for RGB. You then use this as a mask for every image taken from the sensor. Obviously this would have to be implemented by HTC in order to be seamless

Just a thought

I'm afraid you are right. Looking at the results from the taiwanese update we can say it is a hardware issue that might be hidden with software tweaks but only for those who don't have a badly damaged camera - in that situation not even the software tweak works. And we still don't know if those who get the better results after the update won't acquire progressively the red tint issue again...it's a "lose-lose" situation.

We will see in the next couple of days, after the update, the full extent of the problem and where we can go from there. I don't want to say "I told you so" but there were way too many signs that it was primarily a hardware problem, software could not have explained all those problems...Oh well, seems like HTC is on the path of making a tradition out of failed features/hardware, someone at the company seems to be doing a pretty lousy job each year...

[One (M7) Q&A, Help & Troubleshooting] uzman1243:
Here's our test: Produced some interesting results.

We had 10 HTC one phones with 32gb and 64gb versions, varying manufacture dates and varying colors (if that mattered) - all of them brand new.

Initially, there was no purplish tint in low light. The phones were distributed and pretty much all of them were used in the similar way.

We got the phones back after exactly 45 days. This is what we found:

7 HTC one phones had the tint issue and 3 didn't. This is what was fascinating though:

When the 7 HTC ones with the issue was compared to the 3 without we found that:

a) They had a lower amplitude - the quality was the same but the loudness was weaker with the 7 HTC ones with the tint. The difference was noticeable. (note that the volume was put on max in all phones and the same song was used).

b) The HTC ones with the tint issue also had a weaker power button.

So it looks like people with the tint issue also face other minor problems.

We are still recording the data with information like the manufacture date. I will post the data as soon as we finish documenting.

What you should know is that this problem, we believe, is more of a hardware issue and 4.3 will only minimize it but not eliminate it.

If you have HTC care in your country we suggest you keep complaining until you get the correct phone. The problem is that this issue has not got enough attention from major sites like androidcentral and so on. Even HTC wont publicly admit it.'
