Rear camera turn black when use it - Xperia Z3 Compact Q&A, Help & Troubleshooting

Rear camera turn black when use it - Xperia Z3 Compact Q&A, Help & Troubleshooting

Whenever I try to use the rear camera the display turns black while only showing the HUD. The HUD works fine, but the camera doesn't work at all. Nothing is blocking it either.
When switching camera modes (to manual mode for example), an error pops up saying that the "camera is not available"
IMPORTANT NOTE: The front facing camera is working perfectly fine.
Things I tried to do (aside from shipping it for repair):
1. Android repair via the PC companion software
2. Internal reset
3. Safe mode
4. Clearing cache files for the built-in camera app
5. Installing an alternative camera app (the built-in one was disabled)
6. downgrade and upgrade
7.change camera for new one (tested)

I had same situation with regular Z3. Someone brings it to service where I'm working and my first think was camera fault but changing camera didn't fix it. Near camera connection You can see some small capacitors, we call it filters. It looks like capacitors but it's soldered not only on opposite sides but 2 points on both sides. In regular Z3 there was 5 elements like this to change and after that camera starts working. I don't remember how exactly it's made in Z3c but it's really possible that it's the same issue and same way to fix it.
One more thing, if You can check one one more camera to exclude camera itself cause most issues like this are caused by faulty camera. I had many phones (most Z1 and Z1c) with this issue and changing camera always was the solution.
Good luck.

Same Here. Need help too.
Sent from my D5803 using XDA Free mobile app

I have three cameras and two z3c, I interchange camera and phone and always the same result

At this moment I don't have any Z3c to disassembly (except mu own but under warranty) to check where those capacitors are but if You could take a picture of camera connector on motherboard and near area I can mark which one should change.

Main camera not working
I have the same issue with my Z3 compact. The issue started happening on the 11th month of my one year warranty, I sent it for repair (14 business days y + shipping time back and forth). It came back with the same issue. Sent it back right away. After another three weeks without my phone, I got it back. Guess what? EXACT SAME ISSUE!
I called their support line explaining what happened, the guy told me that there is nothing they can do about it since my warranty expired. Of course they didn't have in consideration that I sent my phone before it expired and it took about seven weeks back and forth. There wasn't any sort of damage on my phone, was never dropped or damaged in any way, I never submerged it even if in theory, that would be ok. The report said "it has reviewed the functioning of the unit, unfortunately the defect is in the PCB so it is not able to undergo repairs to it."
The guy on the phone told me what he thought the report meant. It means there is damage on the main board(not caused by me) and the one year warranty manufacturer warranty department won't repair it. Maybe, if I had bought the 2 year "extended" warranty, they could do something about it. I asked if the issue is that my one year warranty was expired or if it is something that they just don't fix unless you get the "extended" warranty. He couldn't answer me and the only thing he said was "is there anything else I can help you with?"
From what I understood, there are two completely different departments, the one year manufacturer warranty that only cover some things. Not even sure what, because if it's broken screen, water damage or any physical abuse, they won't fix it. If it's a problem with the main board or PCB, they won't fix it either. It is a mystery to me what gets fixed in that department. The other department is the 2 year extended warranty. I'm not sure what they are willing to fix there, but from what they guy on the phone told me, it's more than the one year regular warranty.
Long story short, after two trips to FedEx, at least 8 hours total on phone calls, more than 7 weeks without my phone, I ended where I started. Sorry Sony, never again. Worst customer support I have ever experienced.

At this photo I can see only 4 of this capacitors and marked it, maybe it should be four or one I missed cause quality. Anyway regular Z3 has 5 like this and after changing all 5 camera start working again. You can desolder it from most Sony phones, I used capacitors from MK16 (Xperia Pro). So find some Sony board with capacitors like this and ask someone with good hot air solder station (if You don't have one) to change it.

Any news to this problem? I bought used Z3C with black rear camera problem because it was cheap. (Yes, the front facing camera is working perfectly fine). So far I have only tried software fixes and obviously they didn't help. I ordered new camera module from ebay and I'm now waiting for it. Has anyone tried soldering new capacitors if the new camera module doesn't help?
EDIT: Here is another thead with same problem: http://forum.xda-developers.com/z3-compact/help/rear-camera-hardware-detected-black-t3231509

As I said I've done it only in regular Z3 but If You gonna try give me some info is this solution is also working in Z3c case.

I'm still waiting for new camera module. If the new module is not working I will try soldering new capacitors. I will keep you up to date here .

Any news??

Completely forgot to post this, hope it help someone. I made the same thing with black camera on my Z3c. After I broke audio port in my Z3c and had to send it to warranty I took my gf phone, Z3c also. I restored my TWRP backup to her phone and all except camera was working. Camera was completely black but only main, front was OK. After that I was afraid that it's another hardware problem like Yours but after reflashing to stock problem gone. I repeated it few times to check if I'm right and I was. After flashing backup from another phone even without TA and Kernel backup there is a problem with camera.
So I was wrong saying it's only hardware problem. If anyone still has this issue and didn't reflashed his phone check it first.

@Chamelleon yes it's somehow a software problem (if we could say that ). For me i did fix it.
I did a Nandroid backup for my black Z3 compact (camera works properly) an restored it on my new White Z3 compact (also camera woks fine). after restoring the white z3c rear camera shows black screen, the front one is good.
=> i did a format factory reset : didn't work.
=> flashed a TFT file : didn't work.
=> flashed a D5803_23.4.A.1.232_Customized FR.ftf : IT WORKS !
and then i remembered that my phone was from "SFR" , a french network provider.
i hope this helps also

Edit: too new account, would be nice if a mod unlocks the posting of the direct image links and fixes the links - I think they are useful as this is a common problem and i already invested hours translating russian and documenting my research nobody else should have to do it
for me it was a hardware problem after dropping it.. I even changed the camera module.
Did some reseach, russian sites have some input:
Layout1: directupload.net/file/d/4472/9andayji_jpg.htm
Layout2: directupload.net/file/d/4472/vzvgbqqo_jpg.htm
It was loose, but when i tried to push it down with a hot metal to "solder" it, at some point it jumped away and was lost because it is so tiny!
Missing part: directupload.net/file/d/4472/qmut35qt_jpg.htm
The russian site suggest this soldering of bridges, however its not clear to me if they mean one of this electronic pieces (4pins each) or also the lower one.
Russian: directupload.net/file/d/4472/ag43kmda_jpg.htm
The question is now how these (likely) filters (because so close to the camera have to be bridges, it seemed to have worked for some russians:
Pins: directupload.net/file/d/4472/k86j53hr_png.htm
Not sure if there are 4 indipendend pins or if for those small footprints of electronic devices they use only the edges and then they have the same signal.
I was not able to see any text written on those two things, however i didnt have any magnifying glass.

So I changed my camera because I thought it was a hardware failure (tried every other method before: going back to stock, wiping camera files etc.) and it STILL is black. Did you have any success with your camera?

Try flashing stock ROM based on your country as i mentioned up.

Me not (also changed the HW cam), the guys on the russian site yes (even with other similar sony).
Just check if there is something loose, maybe you are lucky and its a software problem *fingers crossed*. To me it happend exactly after dropping (and changing the screen which went without problems) so I was quite sure its HW based.

Hi basmok,
First off thanks for the research and for the pictures!
I have a similar story, phone was dropped, rear camera won't work, tried different ROMs without any luck then took phone apart and saw that one of the four tiny capacitors
just fell off and now it's MIA...
The last pic from your post (directupload.net/file/d/4472/k86j53hr_png.htm) which I assume shows the soldering of the bridge doesn't seem to work...
Do you still have that pic?
Also did you make any progress on the camera fix or gave up?
Thanks,
Ati

You were lucky, they were already in the recycle bin and deleted on the camera. Best I could do picturewise, i dont have a macro lens. Here we go, added all to imgurl so hopefully they survive longer: http://imgur.com/a/Of1DY
And no, didnt make any progress as i dont know what component they are. Normally all components have lasered some code but not sure if its just too tiny for my eyes or if they dont have it. I was a bit unlucky as i didnt have a soldering tool, so i tried it by pushing the pin down with a paperclip which i headed with a lighter --- well it jumped away and was not the best approach

[Q] Camera, LED, headphones not working. Hardware issues?

My girlfriend's N1 has gradually developed some problems. At first the headphones were not being recognized properly. Then camera stopped working. Now that I've taken a look at it the flash light does not work either. If you call someone, 4 times out of 5 the screen goes blank and you cannot end the call. Sometimes this happens when receiving calls as well.
I was using CM7 before and no additional apps were installed. Tried with or without SD card, rebooting, resetting to factory defaults, putting another ROM, restoring to factory ROM.
The symptoms:
- any camera app starts with a black screen and later throws wait/close dialog
- flashlight apps seem to work but no light is coming out
- headphones do not get recognized, tried 4 brands, compressed air, pushing, pulling, pressing. Not a lint issue.
- immediately after pressing a call I get a black screen which I can come out of by pressing a random combination of keys
I tried moving the camera and LED modules with my finger but nothing happened.
Everything else works: calls, trackball with led, bluetooth, wifi.

I had a similar problem with the flash and camera and it was fixed when I swapped out the main board which also has all the ports your having problems with

That sounds unfortunate because the original seller has now closed the shop: site is offline, amazon and ebay products are delisted, does not respond to email.
Even worse, I'm located in Germany and bought the phone here, but I don't really speak the language well enough to contact consumer protection authority and even the HTC support site is all in German. Original box and warranty are in my home country. Sounds like a recipe for disaster.
I've written a mail to HTC support since GooglePhone has closed shop as well.
Since I'm still on a rant, touchscreen has been acting up since day one, upon heating it registers wrong touches, but this is already a known issue.
It was a nice phone while it lasted, but in hindsight I wouldn't recommend it to anyone anymore. It still looks like new fwiw.

same problem

Hardware
Its hardware issue caused mayb y dropping the N1
so try to replacing ur main board or mayb u can get it repaired if u have a good engineer around u
Thank If my reply helps u ..

Just as an update, the issue with all these phones is the ribbon cable connecting headphone jack, camera, proximity sensor and perhaps [front] speaker. It's probably an easy replacement and the part cost is around 25-40$. The cellphone repair guy said that he has done it a lot of times for this phone type, so it's probably a production/engineering issue.

[Q] Problem with flash

I have this issue that makes the photos taken in low light conditions (totally dark sometimes) with the flash on have a white and sometimes blue hue on the right side of the image. I don't have any case/ screen protector on the back side of my phone and the lens is absolutely clean. I've called the guys at Sony Xperia support and they told me to use the diagnostic tool to see if the camera and the flash were working and asked me to repair my phone with PC companion software update. Even after going through all of this there seems to be no change whatsoever Has anyone else had this problem with their xperia z1?

You have the same problem with the camera like many already reported.
Same here: http://forum.xda-developers.com/showthread.php?t=2613386
I also had the same problem and like many said to me, I telling this to you, learn how to use the camera on the phone.
I know this seems rude and I agree with you and I also do not agree about that because I don't spend a lot of money to waste my time to set up the Camera properly to avoid white ghost on my pictures, specially when I use iAuto Mode.
So what is the main reason and problem here? Like I already said this many times, the flash is too close to the lens. Technically nobody can said I am wrong if I said that because all we know if the flash will be more distanced from the lens we will get better pictures. Not all the users have this problem too, let's clarified here.
Now the solution is just only one, with some options you can avoid that and try different method to avoid the white/blurry shadows on your pictures. Many posted different type of solution and different settings so I can suggest to you only one thing, try and find the right options by your self, good reason to understand how working the camera too.

thank you. Will see what the guys at the service center are going to say when i take my phone to them.

Took it to the service center where they told me that they would install the "Original" Software ( a thing only they would have according to them) and that it would take 2 DAYS to download it. they didn't even listen to me when i said that i repaired the thing with pc companion. Whenever i have a problem, these guys seem to think that flashing their ORIGINAL firmware would magically solve all the problems.
EDIT : Got a new phone after they replaced mine and even the new one has the same problem. Guess the person who decided not to put a flash in z ultra was a genius

[Q] Camera stopped working after screen replacement

Hello guys,
As the title says, I replaced my P880 screen because it had an awful crack on it. The thing is that after I changed it, back in my house I tried to take a picture, but it said that it couldn't connect to the camera, or something like that. This had happened to me before, so I restarted the phone and nothing, so after reading some blogs (no one exactly related to the camera problem) I decided to make a full wipe of my phone and restoring it to factory settings. Always hopefully, it didn't work so I realized that the guy who made the replacement might have forgotten to reconnect the camera socket (is that the correct name?), but I can't take it to the service center to get it fixed because they are closed on saturdays and I can't go on monday because I'm leaving the country for a few weeks.
So I was wondering if I can make this check in my house, which tools would I need and, the most important thing, what and where should I check that is connected to the mainboard.
Thank you very much in advance, really hope someone can help, as I need the camera :/

Check my repair thread in the general section. I list all the tools needed and am pretty sure you only need to remove the back plate covering the motherboard. The camera module should have a cable, follow it and make sure it is pressed in all the way.

Random black spot in camera

So I went to take a picture today and noticed a black mark on my camera (not the actual one bjt when I open it) I looked st the physical camera and its clean no searches marks or dirty. I cleaned it anyway and the mark persisted. I've tried 4 camera apps, 5 backups (Nandroid) and I can't figure out why it's there. It only showed up this morning and I'm out of ideas.
Does anyone else have this issue, or has anyone had this happen to them before?
I'm going to call moto for a RMA later tonight but I wanted to check here first. There's a picture down below of the issue its in the upper left corner. Enjoy the random poorly taken photos of the issue.
Edit: this issue doesn't exist in video mode, so it must be a software problem. Ill try restoring to stock and see if the issue persists.

Have you contacted the developer of the ROM you're using? Try looking through the forum of it and see if this is an issue for others as well. Other than that, re-flashing the rom would seem to be the best course.

I have the exact same problem before on my Xperia Z camera. It was the camera sensor, probably dust. Had to send my phone in to have the camera module changed.
Edit : I guess you better RMA your phone.

I was hoping I wouldn't have to RMA it, but its rather annoying when I take pictures. I'll give moto a call on Monday.

Just noticed this random black spot on mine as well. Came here to see if I was alone.

I tried everything from flashing the stock image to cleaning the lens with my old DSLR lens cleaning kit. The spot wouldn't go away so I RMA'd it.

So did you get the phone replaced?

same thing happened to me but i had a larger one. already got a replacement (new seal) and sent the old one back today. Just waiting for my reimbursement deductible.

No Audio after screen replacement

Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!

you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<

Little update,
Just connected a bluetooth speaker,No any sound nothing..

Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!

Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!

Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.

That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...

have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month

Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all

found the schematic here

now on the journey to repair this stupid mistake, lol
any help from someone who are an expert in this thing will be really appreaciated

Yeah, tried it before, and the audio chip is gone
Perhaps something wrong with the audio chip, will try to replace the IC tomorrow
