Noticed the problem in CM-10.1 yesterday. The screen gets completely red/blue noisy in the dark or with covered camera.

Tried again with CM-10.2 today, then with the Sense backup and then with GPe 4.3. Sometimes it's a bit less (just dark red instead of completely red), but it's always there.

Checked EXIF - data for the sense camera was ISO1000; the FV-5 got resized and your ISO value isnt there
[One (M7) Q&A, Help & Troubleshooting] 12rithy:
It is wasn't resize and I just checked that Camera FV-5 didn't save any EXIF metadata. But I was shoot in everything auto. I was shooting about 1 hour last night and no red tint appear in Camera FV-5 viewfinder at all. So it is not the heat problem in my case.

Could people that just got problem after amount use of time test Camera FV-5? It was surprise me because the app didn't help this much in my old unit. My old unit got the problem since the open box day.

The same with Sense Camera. Only Camera FV-5 that different.
[One (M7) Q&A, Help & Troubleshooting] shiningarmor:
so it's software?
[One (M7) Q&A, Help & Troubleshooting] slntdth93:
your FV-5 photo was resized I think - and it lost that ISO value

The lower your ISO value, the darker your image appears (usually) - and as a result, usually less noise
[One (M7) Q&A, Help & Troubleshooting] xmfpdlemalnz@hotmail.com:
For me, if I cover the lens initially and then start the camera, it will stay black - no reddish tint.

However, once the lens been exposed to any light then the reddish tint will happen if lens get covered.

For this reason I think this is a software issue. Plus it only started happening after I upgraded to 4.2.

I used to take pitch black photos with flash all the time and didn't realise this issue when I was on 4.1.

For Samsung phones, they have a separate firmware for camera and once it's updated, it won't change/downgrade regardless what Rom you flash. Sort of like bios update on your computer.

Is there a such thing for HTC phones? Maybe we can compare firmware versions..

Also where does the "sys" come from? mine shows the date I formatted my phone before flashing a rom today but looking at the rom with winrar theres no "sys" folder to flash so is this from hboot or something?
[One (M7) Q&A, Help & Troubleshooting] Riyal:
It's coming from the kernel. The kernel creates all the sys contents. It's called sysctl and it's like the registry of windows.

So months have passed and still no definite answer to this issue. :(

I'll post pictures soon.
[One (M7) Q&A, Help & Troubleshooting] dcemtp1:
So mine was perfectly fine, I would cover the lens and it would be all black. Plus I have the one with a cooler white, not the yellow screen. All was fine and dandy until I read this thread and someone said that if its fine until it sees a little light. After trying it out, mine went red too and I can't get it back to regular anymore lol

The auto iso just gets way to high, anything past 800 and it goes blue then red? I definitely think it's a software problem now.

P.s. I've been totally stock since day one.

There can only be one, the chosen ONE.

I'm very confused.. Yesterday take some pictures...

The second with focus on candle.. simply AMAZING!
[One (M7) Q&A, Help & Troubleshooting] Xerro-Five:
Why are you confused? The second one is less exposed because it's focused on the candle which is why you can see the flame in better detail and why you lost all the detail in the background and so of course noise goes away as well. I guess it depends on what you want to see but any smartphone camera can take the second picture, only the One could take the first so that's the one I would be aiming for.

Do you guys think that HTC removed the optical image stabilization on the One Max for a reason related to our problem?

---------- Post added at 02:10 AM ---------- Previous post was at 02:04 AM ----------

If you live in somewhere cold and don't play games too much, then I think that you should get it. My friend who's in the UK and got the phone earlier than I do never had the purple tint. Even if he covers the lens for too long. I bought mine later in the UK (at same place btw) and the purple tint only started when I moved to a hot country (my home) for good. He wishes not to come home (we live in same country) due to this lol.
[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
Hamdir(for those who know him) bought 3 different One at different times and never had purple tint!

I don't know what to think now.

You are saying ALL One get it sooner or later but some people never had it even after 6 months.

I know a guy who sell phones delivery at home,he said that I can try 1 week the phone,if any fault appear he will replace it,his phones are October/November batches,purple could appear later in 2 or 3 months though.

He also have other brands so I can ask for a swap within a week
[One (M7) Q&A, Help & Troubleshooting] afhum:
It makes me wonder how he managed that. He's so lucky..Yeah I guess some people don't get the purple tint, like my aforementioned friend. He uses his phone normally like I do. Play games often like dead trigger 2. Take photos. Etc. All those things that can warm up the phone.

A lot of pepople are having the issue even with october sensors..

http://xdaforums.com/showthread.php?p=47909120#post47909120

Its a heat problem, and im sure it cant be fixed without change the design of the phone itself, thats why HTC is "repairing" and not replacing the phone, and thats why every HTC you try out have this problem eventually (event the launch ones), the only difference is how much heat can take the sensor they put in your device.

And let's face it, the common user wont even notice this problem, they must think is "normal" and just live with it, and turn a light on.

---------- Post added at 04:29 PM ---------- Previous post was at 04:23 PM ----------

The key is: The temperature in the country of those people who do not have any problems.

In my expermientation I saw that only 1°C of difference can make the tint appear.

Also, if I just turn up the air aconditioner of my office, and set the temperature in very cold (17-18) the phone NEVER shows red tint.

Yesterday was a very hot day on my country (30°C) and the red tint was present almost all the time.
[One (M7) Q&A, Help & Troubleshooting] ERamseth:
OK so Just to close the loop on this. I got my phone back and it seems to work great. No tint of any kind. The sensor date is 9-22. HDR Video looks ok as well.

And with the one that say that another with a phone repaired has the problem again, it was the new cinesensor?
[One (M7) Q&A, Help & Troubleshooting] patpatforxda:
Problem realky gets worse with TIME. Could be realted with SW and kernels and daily usage. Of course with heat, it's given. But it just gets WORSE.

Got this phone in June. Low light was okay although completely blocking the camera gives purple tint with grid lines.

3 months later, low light capability has worn off. Even indoor shots with good lighting, extremely good lighting, will give purple borders.

Months later, waited for the 4.3 "fix", negative. And I just noticed, coincidentally right after my 4.3 update, I am sure the grid lines got worse on indoor shots with decent lighting. And yesterday we went to an outing and realized that the grid lines even appear on DAYLIGHT SHOTS. Example is attached.

Grid lines would appear depending on where I tap to set the exposure. But this was a spontaneous shot. Captured with settings all on auto. I did not tap anywhere.

Even shots with GOOD LIGHTING ARE NOW AFFECTED.
[One (M7) Q&A, Help & Troubleshooting] ddearce:
How is your weather where you are? is hot? how much?.

The problem appears after you reach 34.5C° (95-94F), you can check the temp of your phone dialing *#*#4636*#*# and then choose battery.

This problem is called "amp noise", and is electrical interference to the sensor, the sensor has a bad shielding.

If they just keep replacing the same sensor (same model, same shielding) the problem WILL come back after some use and degradation of the shielding.

You can correct (sort of) this noise using exposure-controller apps, like Camera FV-5.

To reduce the heat from the phone, and have more time to make a shot or record a video, you can set power save mode on, and limit the CPU.

All of this can HELP but not fix the camera, even replacing the sensors will NOT fix this issue until HTC improves the shielding of the sensor.

This can be helped via FW also, but its a longshot, maybe with 4.4? some people reported to having the problem almost fixed with that.
[One (M7) Q&A, Help & Troubleshooting] UgXvibe:
I have to disagree here.. My first brand new One was taking low light purple pictures the night i bought it, less than 6 hours and i had hardly used it. My second new One was good for about 10 days and the problem started so i sent the second one in for warranty camera replacement. Its been a month or so and the camera is performing admirably (And believe me, this phone has been thoroughly tested by me).

Whether it was the newer camera or added shielding it is fixed and HTC knows how to fix it. Whether the 'authorized' HTC service centers are doing what they are supposed to is another story. I can confirm that someone at that Houston, TX repair place is doing it right.
[One (M7) Q&A, Help & Troubleshooting] ddearce:
Are you aware of the plenty of reports of people who got the sensor replaced and got this problem again 3 or 4 months later?

The time will vary for sure, depends on the use of the camera, the weather, and the user itself.

If in my country was winter right now, I will never gonna find out this, 'cause here we have 8 months of cold, below 16C°, and the phone under 34C° performs great.

High ISO in a phone is a bad idea, little room and so much hot and noise.

The Galaxy S4 have only 800 ISO max, and that's for a reason.

PD: Im not blaming the techs at houston, or any techs, it's a matter of costs and bussiness. Maybe the problem is the motherboard, or the design itself, and it's too expensive to totally fix it, who knows, but i know for sure, that ISO +800 in a phone is gonna be tricky, and that is why this problem is happening again to people who got the sensor replaced, from all over the world, and in differents time-frames.

Amp noise happens to every camera, even the most expensives, the longer you got the camera on

Wanna do a test? just go to a low lighted room, and turn on your camera and set the ISO at its highest (1600 i think?), and just focus something, but make sure that the corners of your camera are in a dark spot and wait, but do not let the camera go in sleep mode, we want to have ful exposition, and test how fast the sensor will heat up.

Most of the cameras, after 15 minutes or so, wil show some blue-purple amp noise in the corners, that is normal.

If your phone, after 5 minutes or less starts to show purple-blueish spots on the corners, then it's not properly shielded/heat protected, and that duration will go down with time.

PD: If you live in a cold country its obvious that the test will be affected.

Sorry for my english, its not my prim language.

PD2: The explanation of why the screen will turn all purple/red when you cover the lens or enter a dark room is simple, is 'cause the phone, when detects no light at all, it will set the ISO to the max, in order to get some light, that makes the sensor heat up really fast, and if hets up, and had a bad shielding then the noise happens.

The 4.3 "fix" just make this mechanism work backwards, now when the phone detects a lot of dark, or complety dark, it sets iso to 100, to prevent overheating.

And thats why also some users experiment some "flashing" like a disco in some low light conditions after the 4.3 fix, 'cause the phone says:

-OH SHT! THERE IS NO LIGHT NO LIGHT! I MUST TURN ISO 100, MUST FIX THIS HEAT!

but then detects light

-OH WAIT! THERES SOME LIGHT HERE! LETS RAISE UP THE ISO!

but then you just move the phone a little to the left and...

-OH NO! DARK AGAIN, LOWER THE ISO NAO!!

Result: flashing screen disco madness xD
[One (M7) Q&A, Help & Troubleshooting] lorddavid:
yeah, but, you must see if the sensor of those who the camera fails, is the newer version. I will test mine tomorrow that my phone comes back *only 1 day shipping) and I hope that they replace my camera *forgot to ask them an invoice of what they did). I read that they replace the manufacture of the camera, so, maybe the people who has problem after warranty repair have an old camera ?
[One (M7) Q&A, Help & Troubleshooting] vegetaleb:
I created a topic on another forum to see if there are people without the purple tint because when I read this thread it looks like all the One are affected,and in only 3 hours I got about 6 people claiming they never had any purple tint even with an April unit.

So I wonder if this thread here is negative about the camera because all people in the world who have this issue are posting here and people who don't will never come here and vote or say they don't have issues.

The nightmare yesterday at HTC Lebanon when we opened 3 different One and all 3 were having this issue made me wonder if they didn't deliberately send the bad units to my country hoping people here are not aware of it,or because they are old batches the purple tint had plenty of time to awaken :eek:

Too bad Butterfly S doesn't have a good XDA support,though it's the same sensor.

Damn Peter Chou why did you take this ultrapixel risk?

Got my phone been today from the AU (kddi) shop in Tokyo, first thing I did before signing off on the repairs was download ES and check the CineSensor version. 2012-9-15. They also replaced the casing which was a bit chipped (dropped it the day I was gonna buy a case lol). All for free. But then I pay insurance on phone bill...

So far so good.. Hoping the new sensors will hold up over time.
[One (M7) Q&A, Help & Troubleshooting] ddearce:
The date of the phone doesnt matter, is the date of the sensor who does, my phone was manufactured 1° of october and had the tint problem, and the sensor date is 2013-07.

They are using the same old sensors in the new units, they dont care, if they have millions of them already purchased they wont throw them away.

The only temporary fix is to get a new sensor module, from november, there are reports of people with october sensors faulty too.

And look, this problem is happening since june, they KNOW since june, my phone was manufactured in october and still has the problem.. they just dont care, they will keep using the old sensors until they run out of them, and after that maybe, and just maybe, they will look for better ones.

But again, i bet this has nothing to do with sensor quality, but with shieldind and heat problems, that cant be fixed in a cheap way.

Nice explanation, but could you elaborate on why that duration will go down with time?

I mean yeah, I can imagine dust and all the factors increasing the heat inside the device with time, but I guess you have something else in mind.

Also could you link me to the guys for which the issue reappeared? Except the guy mentioned lately. I am asking because people are just people, and as well as most are not even realizing there is any issue at all, those guys might have tested the camera very briefly, maybe weather in their country has changed, or even they installed a firmware update that heats their phone a little more...
