Question Mi 11 Main camera problem - Xiaomi Mi 11

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.

Camera glitches?

Hello. I received my handset on Saturday morning from P4U and have been very impressed so far, especially compared to my experience with the One X last year where I had to swap 3 handsets before finding one without a major problem.
I have noticed however a possible glitch with the camera. When using the camera outside in bright sunlight I sometimes get glitches on the screen in the form of a jumping/rippling effect which is sometimes accompanied by a faint crackling/clicking notice. On one occasion it would not focus at all, with the screen rippling the whole time and refusing to focus. Following turning off and on again I have not had the problem to the same same degree, although it does happen occasionally with maybe just one of two ripples before the image on the screen settles down. The issue does not seem to arise in other scenarios (indoors, etc). Had I not had the situation where the camera could not focus at all I would just have put it down to the particular way that the camera focuses
Also I noticed that when the issue was most pronounced, I was standing outside our house in a bad/poor mobile reception area, just on fringe of out Wifi connection within the house. The phone was also set to auto update and was trying to do so. Could this therefore be some sort if interference issue interfering with the camera sensor or imaging chip?
Hs anyone else experienced anything similar? I am very pleased with the handset so if this is standard I would not exchange it. However if this is an indication that I have a dodgy camera module or imaging chip I would want to do something about it now.
Many thanks.
Just tried to use the camera to take photos at the theatre in combination of dark foreground and bright background. Camera struggled to focus on a number of occasions, with repeated clicking and pulsing/ripples on the screen as before. Never seen anything like it with a digital camera. Might be something to do with ultrapixel technology but it can't be right can it? Any ideas? Looks like an exchange may be necessary...
Reminds me of another thread...you should check out this thread : http://forum.xda-developers.com/showthread.php?t=2196059
Might be the same problem.
Thanks - I had seen that one too. Not the same effect, but I have seen that issue as well.
I called P4U today and got given a swap code to exchange the handset in-store, which I did earlier today. Not had a chance to test the new one, but hopefully it won't have the same issue as I have not seen anyone else complain about it before.

Do you have a video clip to show the ripple effect you have mention?

[Front Camera] bugged after the 4.3 upgrade

Hi All,
I was wondering if anyone else expect similar or same issue as I do.
I recently updated to 4.3 soft No: 3.62.401.1
Today I was in need of using the front facing camera and when i switched from main camera ( which works perfectly fine) the front camera shows purple'ish lines from top to bottom in horizontal view, they are all over the screen and I can just about make out some shapes behind them.
Front camera functions work and I did test the camera when i got the phone and it was working perfectly fine as well.
I havent drop the phone nor hit it with anything, there are no viable marks on the front camera as well.
I wonder if this is due to software or not ?
Anyone could shed some light on this issue ?
Many Thanks
Kind Regards
I don't have that issue, but I swear since updating to 4.3 the Front facing camera has ****tier resolution or something, waaay more noise going on even in the brightest light - whereas before it was crisp and sharp. Hangouts video calls now look like **** too..
tnx mate
well I'm now thinking if I should get my phone replaced, I got extended warranty on it with insurance so I could get it fixed/replaced in no time.
Still wondering if this not a software issue or not.
I forgot to mention that I have a carrier free version with sim unlocked in factory.
I really think they messed up the FFC by trying to "software fix" their purple tint issue on the back cam
Something they did to the way the software runs the cameras screwed up the clarity and created new issues. That's my guess

Purple/pink tint camera, what exactly is the fault with?

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.

Nexus 6 Camera - Blurry in landscape only

My Nexus 6 seems to have an issue from day one and is still present with the 5.0.1 update and the most recent camera update. I'm unlocked and unencrypted.
When using the camera, any camera app, the viewfinder and ultimately the photo/video comes out blurry when shooting in landscape. If i shoot in portrait, the viewfinder and the photos are sharp.
In landscape is starts clear and sharp and then quickly changes to being blurry. Even resting the phone on a still surface it is always blurry. Lighting conditions or shooting mode don't make any difference.
I attached two photos showing the difference, both handheld.
It's almost like something is wrong with the OIS in landscape. Hardware issue?
did you touch to focus or did you just point and shoot?

touch to focus... it actually begins to focus and then it looks like the sensor is shaking on the screen and shows up in the photos. I have no issues at all when in portrait mode.
This even happens when the camera is sitting on a still surface so its not my hand shaking.
This is with the camera sitting stationary on my desk and a 10/sec timer
mine did the exact same thing. the OIS never fully settles due to a hardware defect. i got a new one from T-Mo and returned my defective one and the problem has gone away.

Thanks for the info and helping verify its a hardware issue. guess I will be calling T-MO then. Where they hard to convince in replacing it?

i was lucky to call and complain about it within the 14 day buyers remorse period so they could send me a brand new one instead of a possible refurbished one, but it was like pulling teeth with them. i had to explain that it was a hardware issue several times before they agreed to send me another one. after several phone calls later in the next few days, i finally got someone who was willing to do it then and there while on the phone.
good luck :good:
I have about the same problem with my more then 1 year old Nexus 6. After my nexus 6 fell of my bed (with a tpu case and no visible damage) it seems that i can only get the camera to properly focus while holding it at 90 degrees (so with the camera sensor towards my right hand) and while holding it at 180 degrees (so upside down) 0 and 270 degrees (camera towards left hand) the camera focusses, during the focussing it's focused for like a fraction of second and then the blurriness/vibration starts, in both camera and video mode.
So thanks for this topic, i guess i'm ordering a replacement camera module.
Replacing the camera module has fixed my focusing problem. The module itself was around 13 dollars on aliexpress. For anyone that's facing focussing/ois problems with the camera, you can easily replace the module yourself.

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.
