Purple/pink tint camera, what exactly is the fault with? - One (M7) Q&A, Help & Troubleshooting

Is it the camera module or some kind of motherboard?
I'm confused it works well from the freezer and I want to replace the faulty part but don't know what the faulty part is.
Opened it up earlier today only damaged the case slightly and it took 10 mins.

The problem is with the Camera Module. HTC confirmed this as a manufacturing defect, they would have fixed it for free.
Anyway to the best of my knowledge the problem was inadequate heat shielding for the Camera Module. Over time heat from the phones internal components (Processor, Battery etc) damages the lens inside the Camera Module producing the purple hue you see in your images. The warmer the device the worse it looks hence the reason it works ok after being in the freezer.
I sent my to HTC for repair I don't know exactly what they did but it came back good as new and so far the problem has not returned. Maybe they replaced it with an upgraded camera module or the same module but improved the heat shielding. Or maybe they just put the same module back in and the problem will return although I've never heard of it coming back after a HTC repair, only time will tell I suppose.

if you removed the back you can lift the camera and insert a thermal insulator , without having
to take apart everything ; you can put a thin plastic .
i could put a small circular magnet behind the camera myself when i was trying to fix the focus problem ,
there is some room.
Also put your phone in power saver it could help for the high temps.

Thanks for the replys, I did try lifting the camera even inserted something to the back of it and left it hanging out it still had the problem so I guess it just needs replacing May aswell replace the battery while I'm at it!
Thanks again

Quick update, I jjust replaced the camera module and it still has the pink tint now I'm lost anyone have any idea what's going on?

Does anyone know what is going on? perfect camera during the day but still pink/purple at night or dark I thought this would have been fixed after changing the module but obviously not is there anything else i can try?
And for those who have taken apart the camera module whats with the little sensor type thing on the camera modules ribbon? is that where the problem lies? a little square box lies beneath the copper heatshield it looks just like a megapixel sensor but is completely covered up.

Lens extends on camera activation and startup

anyone with this otherwise great device will be familiar that upon boot up and camera activation the lens automatically extends.
Sadly, in my case the lens has broken as a result of
1/apps that activate the camera programatically, pushing itsself out of its car cradle physically damaging the lens assembly
2/ Power on lens extension when held in hand like a phone, lens in palm of hand.
I emailed to samsung and suggested they use a proximity sensor ( very common on phones) mounted on the front of the device ( lens side) to check the path the lens will take during extension is clear, or possibly even using data from the focus beam. I suggested that If it cant extend safely then it should not, rather than risk damage to the motors inside the lens. Samsung could actually apply this to all their cameras.
I also suggested the default on power up should be to not activate the camera app, which extends the lens ( after all this is a hybrid device) it may be possible for devs to alter this behaviour ?
It also occurs to me that developers who make device specific apps for this device could win some serious respect if they used the accelerometer Z reading to ensure the camera wont activate when device is lens down/screen up avoiding the lens causing the phone to do pushups which also bends usb connectors.
I know this belongs in the development forums for this device but I can't access them due to having less that 10 posts. Hope someone can add it for me Many apps can activate the camera programatically, it's worthy of consideration as a lens fix costs $200.00 and is not covered by wararanty.
Better yet, if someone could discover a way to make it NOT startup in the camera app. Then the lens would only come out when I actually run the app.
I admire your enthusiasm for making these suggestions to Samsung but they will fall on deaf ears. The simple and certainly quickest solution is put an extra option in settings "Toggle camera on startup ON/OFF"
Done.
it gets worse
yep, that would solve the startup issue but any app can activate the camera programatically, meaning they can start the camera according to any variable, time, location, force etc.
Initial quote to repair was 150.00, but It also now appears the motherboard is damaged, since it is behind the lens, so now the cost to fix is $450.00, just a few dollars short of its replacement cost.
This device can damage its self without you having to touch it.
Pretty serious problem
That's a bit odd. The same thing happened to me more than once but there seems to be some sort of protection against damage as the lens of my camera goes back in after hitting an obstacle (they only need to monitor the current drawn by the zoom motor).

Interesting, I'm sure that mine does not do that, the motor seems quite strong and pushed as hard as it can, perhaps they rectified it in later versions, I bought mine Christmas 2012 which I assume was the first "model " as such. I get the lens error, but it stays out, only returning when you power it off. funnily enough I'm pretty careful where and how i leave it positioned

Device fell down, camera strange now, sounds familiar, fixable?

My device fell down and now my camera misbehaves.
First all camera apps just crashed, screens black.
Then there were just still pictures, sometimes false color or just one color, like magenta all over the screen.
Sometimes picture split in strange ways, doubled and so on.
Now if I smack the phone with the top softly to some hard underground whilst the cam app is running the camera sometimes works.
Sounds if something is loose to me?
But I looked at disassembly on iFixit and I can not see any cables.
Is it fixable? What do you think?

It is definetly fixable. HTC fixed mine, even tho i was running a custom rom, they didn't care. As for fixing it yourself: It has something to do with the logic board. I heard they could be quite expensive.
Yeah sure the manufactor could fix it, but I have no warranty left and might probably be expensive.
Thought more about fixing myself. Logic board...yep guess the cam sits on it and I have to exchange it.
Maybe not worth it too

Rear camera-hardware detected, yet black image. Camera "bus" malfunctioning?

Rear camera-hardware detected, yet black image. Camera "bus" malfunctioning?
Hi
Half a year ago my girlfriend accidentally gave my Z3 Compact a rollercoaster ride in our washing machine (full tour). The screen broke, but it could turn on and everything looked fine (gave no errors) when connecting to HDMI.
Yesterday I received a replacement LCD, which gave it a new life. It seems that everything works except for the rear camera. When opening any camera-app, the HUD is visible, but image is black, and no error. If i switch to front camera, which works, and back to the rear camera, it shows a freezed image of the last image from the front camera.
I checked some debug-apps to see if it detects the camera-module, and it does. If it's connected, alle the specs of the camera is listed, and if disconnected, the module is not listed.
I then got a broken Z3 Compact from a friend, and I tested both rear camera modules in both phones. The modules are working in his phone, both doing the same black screen in mine.
I tried hard reset, PC Companion-repair, updates, clearing camera cache etc., but with no luck.
Do you have any suggestion to how I can fix this?
Do you know where on the motherboard I could look for dirt in relation to some "rear camera bus/chip"?
Thank you for any help!
Edit: And isn't it amazing that this phone works to this extend after 2½ hours in 60 degrees celcius (140 fahrenheit) warm water with soap and 1400rpm? Wow! (Btw., all panels were open, and screen totally broken, so water must have been everywhere in the phone.)
I have a similar issue on my partners z3c after the screen cracked, I have replaced the screen and it works great however the camera shows a black screen. I know the camera module is working as I have tried it in another phone. Having searched for this issue I seen it has effected quite a few others not only those who have opened their phone.
what software you used to debug so I can verify that the phone can also see the camera module
This is happening to me too a year down the line of ownership.
Replaced with new camera from eBay still black screen. Between your experience and mine of both testing the camera we've prices it's not the lens, so what could it be.
Need to fix don't know what to do
The camera module itself may work but the chip which handles the rear camera may be damaged even if the phone works pretty good.
So if the chip or anything else related to the camera is dead, you can even try thousands of camera modules from different phones on YOUR phone, none of them will work.
That's my opinion - guy's who work in electronical industry for 3,5 years now and have seen hunderds of differend kinds of damages on different stuff.
I see what you are saying however it would be nice to have an idea of where any chip/bus is that may be damaged to see if it xan be fixed or is replaceable.

Yes, you are 100% right but there's another thing.
In the present times, in a rush of miniaturization, there's a little chance of such reapair to be profitable. The chip/bus may be damaged but in fact not only one thing may be dead... I'm talking about tiny little resistors, capacitors, diodes, transistors (if there are any on the motherboard...) which are many. I'm not saying it won't be possible to repair the phone but without a proper diagnosis what is damaged... I'd be like looking for a needle in a haysack and everyone can tell you that only replacing the whole motherboard will be worth the time.
But still... this is an interesting case of malfunction... I hope you'll find a solution for this or at least someone else will do it for you for a reasonable price.

Both cameras and Flash doesn't work after drop

Hello everyone, I'd like to say thanks for checking out my thread :good:
About a week ago, I dropped my phone into a ceramic floor with the back facing down. The drop sounded loud however the phone looks intact.
A few checks later, I can confirm the phone is OK, except for both cameras and the flash.
The back camera doesn't work (the Camera app just crashes, Diagnostic shows Camera Not Connected), the front camera doesn't display anything (Diagnostic shows completely black picture) and the flash does not turn on.
I'm currently sourcing parts for testing, but I'm wondering if it's possible that the software may be the cause as well?
Although the phone didn't restart (it still worked fine, minutes before it dropped) I wanted to make sure.
Also, as a double check, I tried OpenCamera and it shows black. There's no "switch camera" option so I think it's showing the front camera.
Once again, thank you for checking my thread
Your motherboard is toast. I have a Z2 with water damage. At first it seemed like the camera module got damaged, but on closer inspection, it has the same problem as your Z3+, all things camera related stopped working. There's no easy fix, you either re-ball whatever chips got loose or replace the motherboard.
Maybe you need to replace only the camera, because I had approximately same problem
I had the same problem, it was enough to replace the camera module for me.
hi I know this is old thread but I just have the same problem,have you fix this?
replace the back camera will solve this problem or must replace both front and back camera?

Question Mi 11 Main camera problem

Hello,
Today I noticed this weird problem with my main camera where a sort of black hue started appearing on every picture I was taking, I made sure that the lens is wiped clean and I even rebooted the phone and the issue is still there. This hue doesn't appear when I switch to the ultra wide camera which is making me think its a hardware issue though I certainly hope it is not. I attached a sample picture, it is not something huge but it is noticeable and it is pissing me off. Has anybody encountered a similar issue before? I only recently got it repaired after the Wi-Fi chip was fried and I'd be seriously bummed if this turned out to be another hardware issue .
Prolly the one who fixed your wifi chip got the inside lense dirty on assembly. It looks like a smudge.
