[Q] Front and Back Camera and LED stopped working after screen replacment

Hi, I'm having an issue with my Nexus 5 which is that the front and back cameras as well as the back LED no longer seem to function. This happens in the stock Camera app where as soon as it is opened, an 'Unfortunately, Camera has stopped.' message comes up and blackness is shown. This also happens in third party apps such as Snapchat where the message 'Snapchat was unable to open the camera. You may need to restart your device ' comes up. In addition, upon attempting to use Tesla LED, the back facing LED does not turn on.
The likely cause that I can see is the recent screen replacement that took place. I ordered this[1] online which came with a new set of cameras as well as a new screen. I took the motherboard, battery and rear case from the old phone and attached them to the new set of cameras and the new screen.
After performing the replacement, everything else worked except the cameras and the LED.
Upon seeing the issue, I tried swapping out the new rear facing camera (that came with the screen replacement) for the old rear facing camera that was in the old phone (the camera still worked before the replacement). After swapping the rear camera the issue was unchanged.
I have tried the following in terms of software fixes:
-Other camera applications - they crash or are black
-Clear cache and application data for the stock camera app - no effect
-Change to ART - no effect
I would greatly appreciate any help or advice that you can offer.

I'd reinstall stock rom and gapps, if they still don't work you know it's a hardware problem for sure. Then troubleshoot from there.

I factory reset the device and tried the default Google Apps, still having the same issues.
Any suggestions for hardware trouble shooting?

As for hardware trouble shooting, being that you know the original cameras worked, all you can do is check the connections . I'd unplug them and plug them back in.
I'd also try flashing the 4.4 stock camera zip and see if that works.

I tried reattaching all of the physical connections and that did not seem to make a difference.
In regards to flashing the 4.4 stock camera zip, would you be able to give me a little guidance as to how that process would occur?
Thanks so much for your help so far.

You'd need to root, install a custom recovery (twrp), use titanium backup to uninstall camera. Then boot into your custom recovery and install the camera zip.

Sorry for such a long response time.
I updated the phone to 4.4.3.
Interestingly the back facing camera appears to have started working. The default camera application still fails to open, but when I use another application (Snapchat) and have it set to try the backfacing camera first, everything seems to work ok. However, when I switch to front facing the application says that it can't find the camera.
In addition, the back facing LED has begun to work again as well.
Previously, I had switched out the new rear facing camera (that came with the casing) for the old rear facing camera hoping that it might changes things. I recognize retrospectively that my method of testing was flawed as it seems as though regardless of whether one of the cameras is/was working the application would not open.
Hoping that the replacement of the rear facing had caused it to start working, I swapped out the new front facing camera for the old one. Upon testing, the issues with the front facing camera seem to persist.
At this point I'm not sure how to proceed. The lack of functionality of both front facing cameras (the old and the new) would seem to suggest an issue with the connector on the motherboard if the problem were hardware based. I'm not sure, though, if the problem could somehow be in software.
One software phenomenon that I observed is that as soon as I try to use the front facing camera, the back facing camera stops working again requiring the application to be reset. This occurrence has led me to question the causation between the update and the new functionality. It is possible that in my testing of the device before the update, I had simply been opening the front facing camera and upon seeing it fail, and trying the back facing camera and seeing it fail (because I had tried the front facing camera), that I assumed it was not working.
If you have any recommendations on how to proceed I would greatly appreciate hearing them. If not then thanks for all your help.

Any updates mate? Did you made it work ?
I opened my nexus to fix the gps. Everything worked fine, until suddenly gps stopped working. I opened again, remove the fix, still the same.
Then my camera stopped working as well. "Cannot connect to camera" or something like this it gave me.
I've updated from 4.4.4 kitkat to android L latest build, and gps works but the camera app crashes, as well as any other camera on market ( either black screen or crash ).
Any help for me ?
Any answer it will be appreciated.

Same exact issue with front facing camera after glass replacement. Anybody find a fix yet?

Camera Noisy

Hey all,
Since I've installed the latest version of XtreStroLite, I don't know if it is linked or not but now when I start the Camera I have some issue sometimes with the focus and the camera keeps trying to focus continiusly so it makes a lot of noise and the camera is unusable! I have to kill the task and start it again and sometimes after 3-4 tries it works.
Since then I've installed Axis 2 and installed Adam kernel. This issue seems to be fixed but sometimes here and there I still got this issue. (Maybe once every day)
Any idea? Is it linked to the custom firmware or hardware issues?

Hello
When I star the camera it makes some noise. Like moving parts on a normal camera . A rather worring noise.
If I have the camera app open and if I tap near the camera lens the noise reproduces .
I have all normal no root nothing . Done several resets.
If u have anu news please tell me
Sorry for English.
Sent from my SM-G920F using XDA Free mobile app

Everything is working fine now but I used to have some issues for sure, the noise was lasting forever until I close the camera

working/not working rear camera

Hi, I need your advice. I have a Flex 2 17 months old. There was version 6.0.1 20C. I tried without a SIM card and memory card. Suddently my camera stopped working. It turns on, but the black image, it starts working the moment the front and rear camera, stucks after a few seconds and camera stopped responding. Sometimes Works and I take some pictures, but is not possible to turn on the flashlight. I tried to downgrade to 5.1.1, did a complete wipe, switched to root, but the symptoms are more or less always the same. Currently flashed 6.0.1. Anything else what to try? Thus it seems as a soft issue

its hw issue
this happens from time to time on my flex 2 . The camera module became lose and it shows error or its just black screen.You can solve this issue by slapping hard your phone few times against your leg.. not a great solution but works. the screen must face to your leg. or you can take it appart and reconect the camera module. i hope i helped .

Rear camera stopped working randomly

Yesterday, I could use my rear camera normally without problems. Now every app that uses the rear camera (Camera, Snapchat, etc.) crashes instatnly without giving chance to switch to front facing camera. Tried factory reset like a million times without any luck. What could be the possible reason and how can i get it back to work ?
HTC U11 Life Android One 8.1.0 (EU/PL) 32 GB

Same problem here...any fix for this?

same problem here, any solutions?

add another person. My wife's u11 just stopped working no matter the resets, forced RUU updates (stock) and everything.
Spoke to HTC they said they'd fix it but said they have no timetable on when they'd return it! They're falling apart.

This is U11 life thread and not u11, and its related to a not working camera module and not the whole device. For HTC repair i can tell you it takes something between 3 and 12 months to get the device back. No joke you can read about these long repair times a lot online.

same issue here. No fix but to confirm it's a hardware issue, I use Google voice commands to say "Take a selfie" - which launches the camera app with the front facing camera selected.
If that works fine, then it is likely a hardware issue with the rear camera, you can contact HTC, though your mileage may vary.
If front-facing camera is also not working, that could indicate a software issue you could try resetting the camera settings back to default. Other possible causes might be the disk / sd card where photos are being stored when camera is launched....

Back camera stopped working completely here, no picture, just black and the camera app closes after 5 sec. Resetting camera app did not help. Other camera app (open camera) has the same problem.
Front camera works from “long tap / selfie cam”

Rear Camera + Flashlight keeps getting disabled... Why ???

I have had no issues at all for almost an year with this phone. I was running oreo ever since I bought this phone. Suddenly, a day or two before upgrading it to pie 9.0, I found out in my Snapchat app that there was no back camera sign. First I thought, some weird snap update, but then I found out in system Camera app, it was even not showing the back camera. Whenever I would click on the rear camera sign from the top in Camera app, it would keep on swapping to the frontal secondary camera and then back to the primary frontal camera but no back camera was working. Also I found out that my Flashlight icon is hardened or greyed out, like it's been disabled forcefully. I can make it work using some other app, but it is frustrating why this is happening.
Now I am on android 9, rooted, and this problem keeps on coming and going. At times the back camera won't even work or open with the error "Camera not working" etc. Sometimes, the back camera would work but with only 3 weirded resolutions, like 12MP, 16MP, and some other. and the video mode will be extremely large or zoomed in at 16MP. Suddenly, the camera will start working normally again with all the perfect default resolutions. I tried everything from SAFE MODE to CLEARING THE CAM APP, RESETTING THE APP, but nothing works. All it seems like that camera has suddenly came to life and has a self-consciousness and a mood which it is controlling itself. Sometimes it wants to work and at times, it simply just gets disabled. Any idea what could be the problem? I am rooted using MAGISK.

Simular camera problems with Lenovo tab v7
I have a Lenovo tab v7 with almost the same problems, the rear camera wont work but occasionally the front camera works and the flash LED is dead.
Running Android 9 Pie as well, but not rooted yet.
Any ideas about what we can do about it, is the camera hardware due to be replaced?

It suddenly started happening almost a month ago, I was on oreo 8 and then upgraded to pie 9 but the problem persisted. It kept working for few days and then started to make problems again. I tried to read many forums for android users with the same problem but still haven't found a single complete fix for this problem other than that the rear camera needs to be refixed. But I am finding it hard to believe that even if camera was getting bad, there is no point of FlashLight getting greyed out/disable from the notification bar. It seems more like some kind of a process is not releasing the rear camera and flashlight module/process.
