[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?

Broken screen, stop work front camera

Hey there, past weeks I broke my nexus 5 screen, was broken only it, fully functionally, then I take that to a store to change it. Now I discover that front camera doesn't work more. Tried with whatsapp videocall, duo, camera app, they all crash. Could it be possible that incompatible screen?Thanks

The screen has nothing to do with the camera as the camera connects directly to the motherboard.
Do you get an error that the app can't connect to the camera or the image from the front camera is blank?

@Manexu - What happen next? Did you got it fixed?
I am also facing same issue. On my mobile front camera is not displayed.

Front camera not working after installing custom rom. Please help :(

So I just decided to unblock bootloader, recovery and all that stuff to get on the custom rom.
Have been tried 2 rom: Evolution X and Pixel Exp
The rom seems to be working perfectly fine and the camera app as well but when I switch to the front camera, it just crashes all the time for any camera applications, I can use the camera and toggle the front camera then slide the phone down a bit and actually seeing the camera works through the small light gap appear on the screen but as soon as the slider full slides down, the app just stops right away without any warning.
How do I troubleshoot this ? Does anyone here encounter the same thing ?
I facetime my mother a lot so this really sucks for these recent couple of days already. Should I switch back to og software ?

If your on EvoX and use this camera: https://www.celsoazevedo.com/files/android/google-camera/f/changelog590/
When you slide down your front camera should work immediately.

Just swap back the rom and tried the app. Well it still doesn't work. Its go black screen for a sec and close the application.
None of the application with front camera works as well.
Is this a common thing ?

No, it seems like you are the only one with this problem. If it above does not solve it, I don't know.

This is a known issue. Start the camera, switch to portrait mode, then switch to FFC. It works fine with the latest Google camera port than with the Xiaomi camera. Once the app has crashed, to recover it, dismiss the app from Recents.

I had it too i switched back to stock then i formated from twrp then if you don't know what to do when you dont have an os don't freak out just connect it to the pc and drag and drop the files/rom into the phone install and you should be good to go

P40 pro camera crash on slow motion

Hello everyone I have p40 pro, when I open the camera in the slow motion setting it doesn't work it freezes and shows a black screen. After about 10 seconds it just shut down and when i try to reopen the camera app into the slow motion setting it just shut down. The only way to reopen the app is Go to settings and Clear cache memory from the camera and then when I open the camera it just work normal but cant use slow mo. Also I cannot use the camera lenses X5 and X10 Optical camera zoom it just don't work, it doesn't switch to the camera. It uses the main camera to zoom in from x1.0 till x10.0 . From x10.1 till x50 does nothing. What can i do?

Rear Camera not working after installing MIUI 13.0.8.0

Hello everyone, after years of resolving my issues just by looking here on XDA, it's time that I post an issue with my Poco F2 Pro. Sorry if my english is not correct (i'm from Italy btw).
So, yesterday i got a notification that told me that i could download and install the MIUI latest version (13.0.8.0), and i did it. Later, when I wanted to send a photo i opened the rear camera and "surprise" it wasn't working. Here's what I found out trying some apps:
GCam >> when I open the app, the rear camera comes out but on the screen i see the frontal camera. If I swipe to the rear camera, the app freezes for a bit and then it cloes itself.
Camera's Stock App >> when I open the app, the rear camera comes out but on the screen i see the frontal camera. If I swipe to the rear camera, i visualize the Macro Camera.
Whatsapp >> the app doesn't even give the option to switch to the rear camera (in fact, i think that the app does not detect the rear camera) but i can easily take photos with the frontal camera.
Instagram >> here i have the option to swap to the rear camera but if I do so, the app freezes and it closes itself.
CIT Mode >> when I check for the Rear Camera, i get the error "get the empty or null camera id".
I brought these examples hoping to show that it's not an hardware problem, since before the update I used the phone and the rear camera easy as always, and i think that the update could have compromised or smth the way the phone detects the rear camera. Anybody has the same problem? Or at least anybody knows how to fix that?

Thx i'll try asap, meanwhile i have a question: erasing all Miui camera data means that I lose the photos that I took with the miui camera?

Nope, it's cache and settings.
Also, check permissions, long press camera icon, info/permissions.

This is indeed the solution if the factory reset does not change anything and before to concluded that there is a hardware problem.
