HTC One camera purple tint possible fix - One (M7) General

Just want to let every developer know, I have a possible way to fix the purple tint.
This is my findings...
When you set your saturation and explosure to -1, the purple tint just gone. But saturation -1 seems too much for the photo. It is ideal to have -0.5 or somthing.
It is nice that if a developer know how to modify the Camera setting and make it default.

Hey,
Tried it on mine and it didn't had that much of a dent.

It definitely has to do something with the saturation..
My resaults:
1. Saturation -2 others 0 - no purple tint but white tint on the sides.
2. Saturation -2 contrast +2 - no purple tint at all and even less white tint! Though i didn't try to snap a photo.
3. Saturation +2 - my screen is ****ing red!!

Or set ISO to 100 and it goes away too.

It's annoying. I had a phone replaced because it had really bad blue and sometimes purple tints in low light pics.
The replacement was fine. I then upgraded to 4.3 (ARHD) with the newest firmware (3.22) and the problem has returned. I still have a nandroid of 4.2.2 so may downgrade.

Funny, i still think this is hardware related, while many people report that at ISO 100 it disappears mine still shows it, even with this trick mine was still pink unless the saturation was at -2 which turns pictures black and white.

It's deft hardware related, not software.. The setting adjustments you talk about might 'lessen' the haze, bit it ruins the picture.. They are bad/wrongly positioned sensors within the phone itself. Unfortunately
*s¡gned

I think it's heat related. Seems that the red /purple gets worse when phone is running hot

Mine is stone cold and it still happens. Since it didn't happen prior to the 4.2.2 update, it definitely isn't a hardware issue.

Firmware related?

I'm fairly sure it is a software issue. I heard somewhere that every camera sensor does this (I think it as in a anandtech podcast) and it is then taken care if in software to make it look good. If this is true then HTC did a pretty bad job of mapping the sensors characteristics.

i havent received the 4.3 OTA update, well im hoping this really aint hardware problem.. hoping too that theyll fix it.

I didn't have it prior to 4.3 so at least in my case I believe it is also software related.

Heat can cause magenta tint to image sensors - this happened also when my DSLR's sensor overheated a bit.
Anyways, I checked mine and seems normal, does not have any tinting - on 4.3 :?

Mine didn't have it at first either. But developed over time.

Yes. My camera was perfectly fine till I updated the firmware. Now it's stuck this way even going back and forth. I don't know if the driver for the camera gets broken or something... It sucks.

Just bought a HTC One Nordic today - it came with firmware 4.1.2 which is now updated to stock 4.2.2 - and I have had alot of purple tint on both firmwares especially on indoor shots - sigh
So much the camera is more or less useless.

Pinkish-red tint on center of camera? (Please try yourself)

Replacement Epic... second screen protector used... and now this?
Please tell me it isn't a bad camera.
This is a white keyboard, yet the center area of the image appears very pink.
This is easiest to see in low light on something white.

http://www.gsmarena.com/a_hardware_fault_causes_htc_hd2_*pink*_camera_issues_confirmed-news-1276.php
which was(/is?) a software issue on the HD2. So is it my ROM/kernel?
...and here http://www.nexusoneforum.net/forum/...-one-camera-issue-cloudy-red-blur-middle.html
Here's the Nexus in an OFFICIAL VIDEO and you can see it from about :10 to :18.
All phones? Are you serious? http://pocketnow.com/thought/clarification-the-pink-spot-syndrome
I've actually found a lot of topics on this, some say it is a software issue, and some say it is hardware... I just wonder if everyone has it, or if I've only started my adventure of returning phones until I get one that actually WORKS. If they are all like this, I'd be disappointed, but not nearly as disappointed as if I have to "roll the dice" again and wait another 3 days and buy another Zagg screen protector.
Changing the white balance to anything but Auto seems to fix this.
Nope. My camera seems to work fine. Took multiple pictures of a white envelope and no color variation at all. Might be your camera or even the lighting conditions of that particular shot that threw it off.
What kind of lighting? It only seems to appear in dim/indoor setting.
Here are three more... all are on Auto white balance, even though the colors seem to change a lot with the light:
Some sunlight (door open, keyboard on floor) - No pink
Indoors + Flash (same place, door shut) - No pink
Indoors (same conditions, no flash) - PINK!
It isn't incapable of showing a pure white, the conditions just have to be ideal.

It's actually the Happy Hacking Pro 2.
The Nexus among many other phone had the 'pink dot' effect.
I noticed this was most common if you have Auto-White on, and quickly open the camera and snap a picture.
The red dot would come up at first when the camera was opened, but once the camera focuses, the pink dot disappears.
Its mainly has to do with the focusing of the lenses I think....
from a epic Galaxy far, far away.
...so does anyone else see this on the Epic? The one site seems to think it's a phenomenon in all cheap digital cameras.

Thanks dito33. Changing the white balance makes photo color looks not so natural (in my point of view). I know lighting will help, but not in indoor low-light environment. I just want my SGS2 to be my first perfect android phone. BTW, i am a bit disappointed with the Pink Spot issue on SGS2 which cost me over 500 pound, not 50 pound.
Still thinking whether looking into exchange my phone to other brand/model or just keep it.
I went looking through all my photos, and can't find that pink tint in any of them. The one thing on this camera that I find annoying is when shooting video, everything will get a green-ish hue to it for a minute, and then for no reason go back to normal.

Ah! This is software related.

This has been an issue since I got the phone
Also, before I make a video, I let the camera go for 20 seconds, then it'll say "recording failed", let it go for another minute or so to see if it fails again. If it doesn't, I'll then go ahead and make a video. This happens on queue every time.
A friend of mine has this exact issue on his fascinate since day one.
he's rooted, but has not tried custom roms yet.

[Q] What Does A Nexus Without Backlight Bleed Look Like?

I've seen numerous complaints about backlight bleeding, and a few pictures of what terrible backlight bleeding looks like.
However, I've not seen any pictures of either little or none backlight bleeding. Does anyone have a picture (or can someone who has a good Nexus 10 take a picture) of a Nexus 10 with none/low backlight bleeding?
I think it'd be a good reference for those hunting for a good Nexus 10. I'm in the camp that doesn't believe there is such a thing as NO backlight bleeding, but I want to see what is deemed "acceptable" by most so that I know if my Nexus 10 is "return worthy" or not.
Here are a few pictures of mine with its backlight bleed. I'm not sure if this is considered as good as it gets or if I should take it back and try for better?
100% brightness, white backlight bleeding in red, dark patch underneath the front camera in blue:

Another picture without the markings in the way:
Sort of an inverted picture to help show the trouble spots a bit better:
I would say that mine is almost same as yours, I don't have that much light bleed on top of the screen ( close to the camera lens )
I have 2 more days to decide if I return or not, this is my second unit, first one was even worse than I have now. Fortunately bought in Staples, so I just walk in store and exchanged it. Hope more people will post their screens. Thank you for this post.
I'm bumping this thread hoping someone would post a nexus 10 without any or minimal backlight bleeding. I'm planning to buy next week and I want to know if its worth it. I'm from the Philippines and consumer protection laws aren't great here and I'd probably get stuck with what I will get. Thanks in advance!
Here's a pic of my Nexus 10 app drawer. Pic was taken in a dark room with max brightness.

Pinkish tint

My phone is having this pinkish tint issue. I can observe this issue on white text and also while watching videos. I want to know whether this is a software issue or the hardware one. If it is hardware issue, I can apply for DOA for a new one. Please advise.

if you are having pink tint in some part of the screen at 0 brighntess then id suggest you to doa it. if you are talking about smearing then its not an issue.
There are several S4 thread covering this ... at the moment it hard to tell if it's HW or SW. Try to read some of the threads and see if the symptoms fits on your device

YES and NO.
IMO this is how AMOLED works and Samsung must find a way to calibrate screen in a way that we can have "real" black with minimal smear, and they just didn't this right yet.
Pink tint in part of the screen is faulty HW
Equally distributed pink tint is SW

Hey guys, finally went to customer care and convinced them about the pink tint. As they didn't have another S4 with them to compare, I told them to compare the whites with S3. There was this bluish tint in S3 and mine with this pink tint. So lot of difference there with these Amoled displays. I got the DOA finally and went back to the shop where I bought the phone. They gave a new one in exchange for this.
But the new one is also showing the same issue with the pinkish tint (for the whole display). I am worried now whether this issue is there for the initial batches or this is a software issue which can be resolved in the future update.

If I receive another DOA, I have to go to the same shop for exchange for a new one. I guess they have received this faulty batch and I would get the same issue with the new one again. Thinking of going to customer care and telling them to replace only the display as it will be still under warranty instead of getting the whole phone replaced in which case I am afraid I will receive another faulty one.

I had this problem with my ATT model
the hot spot in the center usually happens with cmos cameras looking at flat gray colors (like a gray floor)
It might be a bad sensor like we had on the m7. The sensors temps would skyrocket and cause colored noise or something to that expent. Have the phone cool down by turning it off for awhile and when u turn it on launch the camera and see if the pink tint is there. If it appears a few moments after it might be the same issue.

No, They are not doing this just for camera failed error phones. They replaced S5 (exynos version) which had exactly this issue. Pink smudg / hue over entire picture. Even in some moderately lit areas without any grey objects.
In the dark, yes, it does get noisy and blue/purplish on all S5s. But this should not happen in daylight. But it is on some units. I talked to the service supervisor when initially the desk clerk refused to acknowledge the issue. But they indeed had memo from Samsung to either replace the camera units or the phones (those who claimed DOA) if customers complained about this issue.
This is not usual chromatic aberration issue. This is different. It is not happening only on the edges. It is like there is some filter in front of your entire lens. I wish I had saved those images to show what the issue is. I ended up returning the phone in the end. Getting new one in couple of weeks.

Camera problem: red/blue/purple noise in low light photos

Same story from M7 continues with M8. Taking pictures in low light has red/blue/purple noise/tint.

You can clearly see on video and picture heat shielding starts degrading, thus parts of the heat transfers to sensor.
Mine M8 produced in May 2014, serial number HT45.
Sensor is Omnivision OV4688 4M.
You can check sensor via file manager, no root is required.
For example, in Solid explorer:
Choose System Root - Sys - android_camera - sensor - open as - Text file - SE TextEditor.
Please report if you anyone has such issue.

And no, having a definately Defect unit/device does NOT count as comparison or example.
Use your warranty, and let it repair / get exchanged for another device --> problem solved.
No magic unicorn will appear and fix it. Your camera sensor is defect, nothing more, nothing less. Thats what warranty is for.
Don't have this issue here and my phone gets HOT. This is also why we have warranties and insurance. Non htc phones break when dropped, run like crap, or have other issues like built like a mcdonalds toy.
This thread is a non issue in my book.
No issue here. If the M8 would have the same issue as the M7 did we would have heard of it by now from many more users. You just have bad luck I guess and got a bad unit.
It only happens when it's using an ISO of 3200.
When I set the ISO manually, even at 1600 there is no trace if it.

This is a "issue" with GAIN. If you take ANY sensor and maximise the gain (ISO) you will get more noise and these artefacts.
Even my DSL has the same problem with 12800 iso and total black. There will be dots and stuff all over the image. Especially with noise reduction on low or even dissabled.
ISO is just a mather of removing more or less noise from the sensory data. Consider it a radio, maximising the volume will make it hum and other things, stuff that you wont notice with sensible volume/gain. Nothing is free of noise and camera sensors are analog and take in noise and IR-radiation esp if the phone is warm. You can prevent this noise appearing but then you get worse performance in Low SNR (signal-to-noise ratio) situation - like dark images.

Not as bad as m7. I see a little in very specific low light shots.

So is this an issue or not? :/
Last time i got my m7 replaced (about 3-4 months ago) this issue was fixed, so this problem would be gone with m8?
So anyone else having this issue? I was really interested in buying this phone.
no
This blue hue is in Galaxy S5 in very low light. Smartphone cameras have a limit. M7 had a genuine problem. M8 doesn't. Let's just STOP making up an issue when it isn't.

Mine's ov4688 4m too (March 2014) got from Rogers(Canada) but doesn't have any issues at all...you should probably return yours mate and ask for another one

I shot plenty and post before night or low light photo. No such issue as you mention.
Thank you so much guys for clearing things out. I am going for the M8.
