Thanks, I just have to back to stock.

I've been reading some tutorials, but I think all of them are a little old and must dowgrade hboot (I am currently on 1.57 with most recent firmware and radio, etc).

Any suggestion of tutorial for this situation?
[One (M7) General] cyrusct82:
If you look back some pages you will see that I have the exact same results as you. Even at 45°C my purple is not increasing. So I decided to not send it for now.

My phone is bought on March 2014 and the warranty ends on 2016 so I have time to test it. Don't know for you.
[One (M7) General] Skanob:
[MENTION=3751048]bor3d2damax[/MENTION], based on the video (with the guy putting his finger behind the camera), his finger acted as a heat sink. This could confirm that there is problem with the camera module controlling the heat, if any.

The heatsink gel (thermal compound/paste) if I got it correctly, acts as a connector to transfer the heat from the host (CPU/camera module) to the heatsink, efficiently. So having only the heatsink gel won't be enough, can you trying putting on a heatsink (any kind)?

I think the solution is to find a way to divert that heat AWAY from the camera module. Add a couple layer of copper/thermal tape? Or increase the size of the copper/thermal tape at the back of the camera module? Re-shape the copper/thermal tape (and divert the heat somewhere)?

Probably, the principle of a heatsink of a CPU processor on a computer will be applicable. If you notice, most, third-party, heatsinks have aluminum or alloy (I need to be corrected with these, too lazy to do google) then a copper material in them. Both being a combination of fastest transfer of heat from the CPU, then efficiency of releasing the heat. Google will be helpful.
[One (M7) General] skinniezinho:
In fact this phones takes fine photos, only sometimes has this.

This one is from August 2013 I guess, so I have warranty till August 2015.

My biggest fear is that with the increasing number of repairs they start to put the "replaced" sensors back again..
[One (M7) General] cyrusct82:
They cannot repair a damaged sensor and put it back in a phone they throw away after replacing it.

And is replaced with another sensor the Omnivision OV one not the ST one (that for some have the green tint).

So my opinion is to wait if you have still that much warranty. Why send it in service for nothing maybe will appear another problem or the tint will increase and you will be forced to send it.
[One (M7) General] bor3d2damax:
[MENTION=3686133]Skanob[/MENTION] thanks for the help man. Im going to try some of these. If not I'll just buy an HTC One for parts and see if the camera works. This is crazy, why wont they just own up to it?
[One (M7) General] b99721:
Is this a pink spot in the middle?

Though my sensor file says OV 4688, I gave my phone for service in India for correcting green tint esp when using flash, and this pink spot began appearing after it (not that green tint is solved - OTA overwrote the calib file and now its back to square one). Is it possible that they installed the defective st sensor in a bid to correct green tint (in flash) and somehow manually changed the sensor file to display OV? Or is this all in my mind? Totally ocd. ￼

German tech support

Hello,

I have the problem of the purple spots in my camera.

I have read that this is a hardware problem. I bought my phone trough amazon.de. Im traveling to Germany and I would like to get it fixed. Does anyone know how long the German tech service could take to fix that? I will be for 2 weeks for business.

is necessary revert the phone to stock? Im on ARHD 71.

Thanks!

[MENTION=3751048]bor3d2damax[/MENTION], any updates..?
[One (M7) General] bududroid:
Actually my purple tint issue is worst... I notice its related on heat issue

As for now I just using my phone only for music and power saver on so the temp is not hot the purple tint is not that worst..

I have FA37 and have the red tint/screen when placed down on a table. The red/purple only shows up in my pics in real low light situations so far.
[One (M7) General] Theshawty:
I don't believe this can be fixed by having it repaired.
[One (M7) General] Prophet16:
It's definitely a heat issue. I tested it out to see for myself. I let the phone sleep for a bit, tested the camera facing the table, there was no tint. I then turned the brightness on max, started playing Dead Trigger 2 for a bit, the phone was getting hotter, tested the camera, and the tint was extremely bad. The entire screen was pure red, actually calling it a "tint" wouldn't even sound right. Next I put the phone in the fridge for a bit with a fiber cloth covering the camera, and I could see the redness going away slowly as the phone got colder. I think the only "fix" is to keep the phone cool prior to taking a night shot, but who plans out when they're going to take a picture in the dark. This is pathetic.
[One (M7) General] croppz:
Yeah it sucks how it has panned out. I've wanted this phone for so long and finally get it and then I find out about this. Still an amazing device and not a deal breaker for me since I don't take a ton of night shots. I can see how it would really annoy other people though.

Sent from my HTC One
[One (M7) General] phylosoph:
Maybe they can cut the aluminum foil and make it end before it comes near the camera so camera won't get as hot as it used to be?
[One (M7) General] blackhumor918:
probably the temperature is just right.
[One (M7) General] aceonetwothree:
HTC have really stuffed this up, probably never going back to HTC after this
[One (M7) General] jonnyaas:
New Sensor!

UPDATE: got my HTC One back today from the UK repair centre. No purple tint issue! Checked the sensor version to see if they had changed it or whether it was a temp fix and it seems they have - the date on it is 2013-09-24 and i got my phone in June (SH35 May batch) so hopefully it stays fixed! Being that this sensor was made in September is it likely to be a fixed batch?
[One (M7) General] gustav30:
I think you'll be the September batch tester!
[One (M7) General] Theshawty:
Hmm. Interesting twist. I now not only have the red tint, blue tint and purple tint, I now have a turqoise-ish tint as well. As I've always said, the more the merrier!
[One (M7) General] Galactus:
I'll be sending mine in for repair soonish. Just waiting to get a spare device in the mean time from a mate and off she goes.
[One (M7) General] Theshawty:
I don't have a spare device lol so I'm keeping it as it is. Also can it really be fixed anyway?
[One (M7) General] Galactus:
Wouldn't say fixed is the appropriate word, more like replace. Whilst the issue is more than likely heat, i think a new sensor should stop this from happening. Most reports indicate that it happened over time which would suggest that the heat has probably made the sensor more sensitive to heat from prolonged burning. Even more so because the phone had to go through summer lol, poor thing
[One (M7) General] swiftgs:
I don't think all the sensors have the heat issue. My sensor seems not to be affected by heat at all. I run the antutu stability teat twice making the phone really hot. Battery according to antutu 47 degrees and still have zero problems. Clear black image. (see the taken photos topic for samples.

sensor type is: st vd6869(1.0) cinesensor 2013-06-18 on a res HTC one with 4.3 and sense 5.5
[One (M7) General] Galactus:
It's quite possible they upgraded their sensors after a while
[One (M7) General] sauprankul:
So is it wise to send my phone in now even though HTCs official stance is that its software related?
[One (M7) General] io53:
I also seem to have a bunch of colors in poor lightning. Even when I take pictures outside with below zero degrees it's some sort of blue everywhere.

I'm sure a lot of it i could be removed in software, but I doubt they will do it tbh.
[One (M7) General] Xerro-Five:
Yes
[One (M7) General] bor3d2damax:
Heatsink gel didn't work and neither did putting my finger on the sensor so for me it isn't a heat issue. Looking to buy a new sensor or just sell the phone for parts. If anyone is interested in it just pm me. I'll have it up on eBay in a week. It's a shame that this can't be fixed out of warranty.
[One (M7) General] Master Bricker:
HTC replaced my HTC One for free due to the purple tint issue, but when it came back I had that red hue effect in the middle like the one in your picture. I called HTC customer service 4 different times, and got 3 different answers. Long story short, they suggested that if i want it fixed then the only method is go through HTC repair center.

If you are returning the phone back to Amazon they probably won't care what rom/mod you have on your phone. But if you are sending it back to HTC you better make sure you remove the tampered flag from your Bootloader. I had a friend that had their warranty service rejected due to this issue.
[One (M7) General] Alaadragonfire:
Just for you to make sure it isn't a heating thing , put it in the freezer / fridge for a couple of minutes until it gets down to 15-18 Celsius and check the camera , my HTC have the same thing and when I cool it down the tint is gone!
[One (M7) General] bor3d2damax:
yes but is it gone forever?
[One (M7) General] SchmilK:
I just did a rapid replacement on my unit. This was a picture of a black bracket I am 3d printing in front of a black server rack in a highly lit data center which was the tipping point of getting my phone replaced under warranty.

Since I have not seen it posted elsewhere, HTC offers advanced replacement for $29 with next day shipping. Got my new device on 4.3 with hboot 1.55 and was back in business immediately and have a replacement phone with no dings or dents and 0 signs of purple tint anywhere.
[One (M7) General] Master Bricker:
I think he was referring to a temp fix. There is no way I am bring a mini-fridge with me everywhere I go. :D

For those with HTC One that display purple/red tint right away after being in deep sleep this method will not work for them.
[One (M7) General] bor3d2damax:
Lol I figured. I'm ditching this phone anyway. Just gonna sell it for parts
[One (M7) General] Theshawty:
Smart move. I wish I could do the same but being unemployed doesn't really allow such expenses.
[One (M7) General] alangrig:
Anyway I don't see any alternative for now.
[One (M7) General] elpicard:
I bought it like a year ago (sep'13) I think that the amazon option is off the table, right?

Any friend from Deutschland?
[One (M7) General] Master Bricker:
That is a bit sad to hear, but I understand your decision. The HTC One M7 is an extraordinary phone with a serious flaw for "some." While I envy those with perfect HTC One M7 cameras, I too had one of those units with massive purple tint issue.

I think HTC grossly underestimated the importance of selfies and having a perfect camera in today's phones. :cyclops:

Yes, I believe so. Not sure if you are in the USA, but 30-days is the standard here and after that you got to deal directly with HTC.
[One (M7) General] Silentknight101:
HI, im looking at doing what you did to an M7, a couple of questions though,

can you tell me what P/N you bought off Ebay?

also, could you tell me what is the new camera sensor info you have on your phone? Via, SYS/ANDROID_CAMERA>SENSOR

Thanks
[One (M7) General] rocky_mountain:
Thanks for some of these tips! my m7 is fairly new, decreasing saturation helped, but I don't think it completely got rid of the the purple
[One (M7) General] ondris:
Hi !

I just received my HTC One back Today.

I wanted to show you two pics (before and after) in same light conditions:

Just in case some people hesitate to send it to repair! The pictures speak for themselves. :)
[One (M7) General] SpineSurgery:
Sent my phone to Poland (from Croatia). They only replaced camera (not whole phone) and sent it back. Expecting it in few days.

P.S.

They also changed mainboard. Should I get new 24 month warranty now?
[One (M7) General] cyrusct82:
no, you will not receive 24 months. I've sent my Moto Defy for warranty something like 8 times (changed 8 mainboards) they even changed the device but the warranty was like the first phone I bought.
[One (M7) General] Osama Zabin:
Most probably no,you will not get another 24 months.

I send for repair and they replaced the phone for me, for some reason they extended the warranty for 4 or 5 months, not sure if it was a mistake or intentionally extended.

Better you check with them.

Note:

I'm sending my phone back for sensor replacement, as it wasn't fixed first time.
[One (M7) General] Skanob:
any knows where to get the OmniVision camera module?

---------- Post added at 10:01 AM ---------- Previous post was at 09:25 AM ----------

Still worth a try mate.

Have you seen this?

Link to the post: http://xdaforums.com/showpost.php?p=49221114&postcount=498

Quick and revised to "common sense" google translation from the Google Translate app for Android:

There might still be a silver lining here..

Still, the principle of heatsink (aluminium + copper combination) applies here and heat redirection/dissipation to somewhere.

I am looking to get these done myself but I am still waiting for my 2 batteries that I've ordered online. I got 2 M7s here with bloated/inflated battery. Once I have received those, then I'll play around with it. As of now, as you are the current one that can play around with the phone, I'm getting my hopes up on you [MENTION=3751048]bor3d2damax[/MENTION].

---------- Post added at 10:29 AM ---------- Previous post was at 10:01 AM ----------

anything similar to this camera module (2 ICs in the front-bottom of the camera module, very visible), is the higher the chance that its the ST Camera Module:

http://www.parts4repair.com/4mp-back-camera-for-htc-one/

This COULD BE the OmniVision camera module (camera has a different (metalic) cover), but I haven't confirmed. Check out the difference of the two.

http://www.etradesupply.com/oem-htc-one-rear-facing-camera.html

I would need someone to confirm or contact the resellers.
[One (M7) General] bor3d2damax:
[MENTION=3686133]Skanob[/MENTION] thanks for the response I'm looking into getting a camera but I'm not sure if the sensor had the problem or the lens. Don't want to spend money on a camera to find out it's the sensor
[One (M7) General] hazeline:
The purple tint camera issue is really the camera module itself, I had my mainboard and camera module replaced after I had sent in to HTC for repair. I recommend those whose phone are still under warranty, send your phone in to HTC for them to replace your camera module.
[One (M7) General] Fidelcastrol:
Anyone sent phone for this problem with unlocked bootloader and custom ROM ? Did it cause any trouble ?
[One (M7) General] bor3d2damax:
If you live in the US I suggest locking everything and going back to stock. I sent mine s off only and they returned it unfixed.

About the mainboard issue. I guess that's out of the question then since I doubt people sell the main board alone. Maybe I can get a busted HTC one for parts and fix mine up. But I rather switch back to my droid DNA. If I can get it working on freaking tmobile.

ok so my phone is out of warranty and i have the really annoying purple tint issue . Can anyone suggest camera tweaks for low light/night time captures such as changing the ISO, Exposure, Contrast, Saturation etc . In Sense 5.0 and 5.5 , putting the ISO value to 100 somewhat fixed the tint but in Sense 6 there is no option to set ISO at 100, can anyone suggest settings for Sense 6 camera which may improve the situation. Thanks
[One (M7) General] MasterThiefGarrett:
How is it out of warranty?

You have 2 years warranty, and if you've unlocked the bootloader and rooted it, there are ways to undo that ;)
[One (M7) General] Fidelcastrol:
And there we go, I'm now One-less as it's back to Cordon for warranty services regarding this annoying problem !

Will keep you guys updated.

Phone was rooted/bootloader unlocked/s-off...will be trying to S-OFF it again when it's back :)

[One (M7) General] drbibber:

[One (M7) General] drbibber:
i WAS s-off before sending it in... but in the process of making it s-on again to make it stock for my warranty, i accidentally flashed latest rom with hboot 1.56 and now i cannot get s-off again... im so sad...:crying:

(i get the 'Whelp it doest work on your device never ever' message in firewater...)
[One (M7) General] Fidelcastrol:
Weird, some people with hboot 1.57 succeed into S-OFFing their devices. Maybe you should try to install CM, as suggested in the firewater thread. Weird nonetheless.
[One (M7) General] twerg:
Any ideas why my M7 that is perfect condition and operating in perfect way for the camera under 4.4.2 Sense 5.5 is now having purple tint in low light photos imeditely after updating the the latest Australian Vodafone update to Sense 6?

Also when i chnage white balance I get a full on change of colour of the screen, full orange, full red, full blue etc.

I did not have this issue with Sense 5.5 on the same day prior to updating to Sense 6...
[One (M7) General] ankanb:
Heat maybe? The issue is dependant on heat. Did you get your sensor changed since it is a hardware issue?
[One (M7) General] twerg:
NO, should not be related to that at all. Sensor has not been replaced. I have 2 M7 Ones, this one has been perfect since days 1, the second One is a referb unit that is effected by the camera modual issue.

My good One did not experience this until updated to Sense 6, has only occured since then and I have not used the phone that much since
[One (M7) General] matekaneve:
With the sense 6 update first the purple tint issue became a bit better for me. I managed to take some good low light shots. However after couple of days of use it got extreme... I could not see anything but pink and purple color all over the place, even if flash was used. That's when decided to send it in for repair.

EDIT: Could anyone tell me how long it takes to get the phone back? Mine was picked up by UPS on Thursday afternoon and was delivered on Friday at 10am according to the UPS website. It was "Left at store" and "Signed by CASTLE". However when I track the device by using the code I received from htc it still states they are awaiting for device. (BTW I'm in the UK)
[One (M7) General] Fidelcastrol:
Around 10 days or 2 weeks.

Been without my phone since 17/06...wouldn't imagine I'd miss it so much ! Especially ZOE, as my 6 months old kid is doing new things everyday and I love to capture the moment :)
[One (M7) General] Theshawty:
Took four days for me.
[One (M7) General] neosic:
Wait so is HTC paying for shipping on camera fixes now? Last time I tried, they expected me to pay. Didn't end up doing it because I needed my phone and didn't have a replacement at the time.
[One (M7) General] matekaneve:
If your phone is under warranty it doesn't cost you a penny. Here in UK UPS come to collect the phone and will deliver it. If you send the device in and they say your phone is not under warranty because of "this and that reason" then you decide if you go ahead with the repair or not, but you will be charged. You also have to pay an approximately £27 shipping cost to get you phone back.
[One (M7) General] Mathman85:
It depends on which option you choose.

First option is to send the phone to them and they'll repair the problem and send it back. This costs nothing at all for the customer but can take up to 10 business days.

Second option is expedited shipping and a replacement device--you send your phone, they send a replacement when they receive yours. Four-ish day turnaround time, and this costs $20 (more if your phone is damaged or rooted or anything).

Third option (if it's within 6 months of the original purchase) is for them to send you a replacement and a prepaid label so you can send your phone back. Pending inspection to verify you haven't destroyed or rooted the phone, this costs $30.
[One (M7) General] misternazri:
Can i just go to other ordinary repair shop to repair my phone? Maybe just give the camera module and ask them to replace?
[One (M7) General] mdiaz33685:
I had to replace both my wife and mine in Feb, cause that purple tint, it was more at low light issue, and yes after a couple days it got worse for low light.. I have tmobile insurance so I just had them switch for $5 bucks each... then I sold one on ebay, and sold the other to my uncle, he had no issues since then,

You can send it to HTC, and they should fix it for free, I believe under the 1 year warranty... they will replace the camera, if I remember correct....
[One (M7) General] eoinzy:
I got mine back today after 6 WEEKS!!

Anyway, the purple tint issue is fixed and my sensor reads "ov ov4688 4M".
[One (M7) General] matekaneve:
I'm still waiting for mine. HTC tracking site states repair is finished and it's already shipped. However ups tracking code shows nothing yet... Hoping it will be with me soon...

Advanced RMA

I'm in the US and I went with the "Advanced RMA" option. I received mine two days after calling HTC and then completing the credit card info form on their website. It was possible to receive it the next day but I'm guessing it depended on whether they already had a replacement device prepped to ship or not. They sent it to me UPS next day. My replacement device doesn't exhibit the purple tint problem, either.

The sensor file shows:

ov ov4688 4m
[One (M7) General] matekaneve:
Just an update on my experience with UK repair centre. I received my phone back, immediately checked the sensor and it is the ov ov4688 4m. The phone is fine however came back with fingerprints and was quite dirty in the back. There is only one issue. There is a small gap at the voume rocker. It works fine, but the small gap bothers me. However I don't want to send it back again as I'm quite concerned I will get a replacement device with other issues. So I just have to live with that little gap... :( Otherwise the phone is fine and a camera seems ok.
[One (M7) General] alangrig:
Because of this gap, I've mine 6 times to Poland SC. They couldn't fix it.
[One (M7) General] Osama Zabin:
Not only at UK, here also in middle east, I got a second replacement for my phone, finally it has the ov sensor, it's brand new, but has two gaps, upper left and lower right corners. So two corners with Zero gap, and two with few millimetres gap.

I remember that there were many complaints regarding these gaps one year back when the phone was released,even before addressing the camera tint issue.

I'll not send it back to service centre. Seems it's difficult to get perfect HTC One,first two phones were having tint and perfect build quality, third one has the OV module but with lower build quality.
[One (M7) General] matekaneve:
I forgot to mention in case somebody is still hasitant, I sent the phone in with stock rom and "relocked" bootloader. It was never questioned.
