Main camera not working - Nexus 5 Q&A, Help & Troubleshooting

Hello
The camera on my nexus 5 stopped working three days ago. I used a CAF CM rom then.
First the Google Camera app crashed every time I tried to launch it and any other camera-related apps said "Can't connect to camera".
I wiped the chache through TWRP restarted the phone, the camera worked at first try, but at second try it crashed again.
Then today I reinstalled the stock 6.0.1 from the Google site with full wipe.
Now Google Camera app says "Can't connect to camera" and every other app automatically uses the front facing camera without having the option to change it.
May it be a hardware related error? Would replacing the camera module help?
P.S (the data in the signature below are really old)

Liquidsmooth 2.37 camera problem

I just recently flashed Liquidsmooth 2.37 on my galaxy s3 along with the gapps. Everything is working fine except the camera. Whenever I'd go to my camera, it crashes and says "Gallery has stopped". Help please!
Same here. It worked fine yesterday but today suddenly crashing. All around good ROM but for this
EDIT: did you happen to set storage to external SD?
I see camera problems as well with third party apps like Instagram and Camera 360. Trying to take a photo with the front facing camera in either app causes my phone to reboot instantly.
Same problem
Me too, the camera worked at first and now it force closes every time, also with 3rd party apps.
I tried installing quickpic and that didn't work.
I don't have an sd card (is this a problem?)
i really like this rom! please help if anyone figured this out?

broken camera?

Hi guys,
I've owned a Pixel 2 since Dec/17 (bought i the UK... so no warranty in Italy), two days ago I started having some trouble when using camera: phone hangs, camera can't get focus... but in the beginning a simple reboot fixed the problem...
This is until yesterday night, when the error worsened: now each time I start Camera application it force closes, even if I launch third party camera apps they crash...
So I tried clearing cache and data for Camera app, but still no luck.
I then tried to factory reset my phone, and reflash full factory image, but I'm still getting the error... sometimes the camera works but it's a rare event.
Has anyone ever experienced this issue? Is there a reset for the camera hw?
thanks

Years ago, I had the exact same problem with my S4. After trying all of the things you have, and a few others, I used the dialer code for the hardware test menu and found that the front camera had failed. Got a new one off Amazon, installed it, and everything was back to normal. I honestly don't know what, if there even is one, the code is for the Pixel 2, but I believe there are some apps that will do the same thing.
camera was broken... tried times and time to reset recovery and so on...
but the solution was to ask Google support, they replaced my Pixel 2 with a brand new one (full sealed box)
i was used to Samsung and tought it would be impossible...
Point for Google.

Solution for the "Cannot connect to Camera" issue?

As my N5 was getting slower and slower, I did a factory reset but later decided to flash Resurrection Remix Pie as it seemed fast as well. That fact turned out to be true, however, after the custom ROM had been installed, the Camera wasn't working anymore (the App said "Cannot connect to Camera").
I experienced the issue with my previous N5 from time to time, after I installed a Custom ROM, the issue didn't go away anymore.
I know that in some cases, rebooting, a factory reset or checking the camera connection to the hardware helps... But the first two options didn't work out, and why should the camera connection be bad after flashing a Custom ROM. Also, I tried various camera apps but the problem remains.
Therefore, I'd like to know, if there is a software solution to this issue after almost 6 years.
Reading your post, I assume the camera NEVER worked after you flashed the ROM, right? Strange... I am on the same ROM, I have installed a GCamera 3.2 app apart from the camera app that comes with the ROM. I get occasional "can't connect to camera" errors on both, but usually a reboot fixes the issue. Try a Google Camera 3.2 apk and see if it works. If not, I guess it is a ROM issue, and maybe you should do a clean install again. Are you rooted? Because for some reason this ROM does not play well with Magisk, when they are installed together at once. I ran into some minor issues myself (see here: https://forum.xda-developers.com/showpost.php?p=79599654&postcount=686).

Nokia 8 - Can't connect to camera problem

Hello,
on Nokia 8 when camera is launched, the camera app falls with error "Can't connect to camera'. It's happening after factory reset on absolutely clean phone.
I think it's not a hardware problem because after restarting phone, the first launch of camera is working but when I press home button and open camera app again, error appears .
It's not about bad app, because this is also happening with Whatsapp, Instagram, GCam, whatever.
Phone has the latest update.
Is there any help for this issue? Are there any Nokia 8 owners with same issue?
Thank you very much.
Hello all,
Since 2 weeks the same problem with my Nokia 8 / 128GB; TA-1012
Camera firmware: V100.0098.01 / V020.0072.01
After it first occurred I did a factory reset and I was able to make pictures from all apps.
Then I could make a number of pictures after each other.
From today making only one picture is possible, then it says: Camera error; can't connect to camera. After restarting the phone I am able to make one picture, just as @gibby1 .
Please help.
Thanks,
Hans
Update: After the last time switching the phone off-on I am able to make unlimited pictures/videos, with both normal and selfie camera, from various apps. We will see how this developes.

Galaxy S7 error message camera app still doesen't work irregulary

Hello, I have a problem with the camera on the Galaxy S7. Previously I had a custom rom for one ui 2.5 and there the problem was that the camera stopped working irregularly (error message the application still stops working. I changed to another custom and it is exactly the same. Restart helps ( fixes the fault for a while), but sometimes the camera is needed suddenly and does not really want to reset the phone Do you have any ideas what this could be? I did clear data and cache but it didn't help
