Back Camera not working

Hi i am currently using the cyanogen nighlty build from 20160114 and the back camera of my device is not working if i use the default camera app.
Only the front camera is active and working, but there is no button for changing the active camera.
Has some one else problems with the back camera? Could this be a software bug or is the back camera of my device broken?

HTC One M8 rear camera

Hi, my rear camera on my M8 it was working fine until few days ago when it suddenly stopped. In the camera application i am only able to switch between selfie and photo booth. Also, rear flashlight is not working, application is loading infinite. I tried to clear cache/data for camera app, disable/enable, uninstall updates, downloading retrica (it just shows black screen for rear camera). Also, i flash a new RUU MM but the problem is still there, so i guess it is a hardware issue. Anyone had similar problem or any other ideas ? Also, if rear camera is failing flashlight cannot work as standalone ?

After i upgraded to MM the problem was solved. Yesterday the problem returned again. Can anyone help me ? The warranty has expired.

Anyone ?

[Android 9 Root] Front facing Camera can't take photos in other apps.

To start, I'm using stock ROM patched with Magisk. Root is fully working and all that jazz. This is quite a peculiar issue, I don't even know where to start. My A50 (W/Canada) is not able to use the front facing camera to take photos in any app other than the stock camera app. This is important to me as I use Snapchat and Instagram frequently. However, I am only unable to take photos with the front facing camera, videos still work perfectly fine, and the preview of the front facing camera also works perfectly fine. No issues with back camera, everything is fine there. I've tried launching Magisk as core only, and undone all my debloater settings. Every thread I see about camera issues said it's either a hardware issue (which I doubt is the case for me as the camera worked fine before root and still takes videos) or a software/kernel issue in which I should revert to stock. I would really prefer to find a solid solution to this rather than revert to stock, so I've come here hoping maybe somebody can possibly shed some light on something I may have missed out of frustration. The only thing I could think would possibly have an effect was the Magisk Samsung 4k60 Camera module which I uninstalled immediately after as it was crashing the camera app when I opened it. Could it have changed a file permanently?
To recap:
Front facing camera works perfectly as intended in stock camera app.
In any other app that uses Camera (including 3rd party camera HedgeCam) I am able to take videos but not photos.
Front facing camera preview always works fine.
Tried Magisk core only mode and reinstalled all debloated apps.
Snapchat gives error (when taking front facing photo) "Snap capture failed. Please try again." all other apps just freeze on (what would be) the photo/photo preview until I exit or switch out of the app then back in.
Any help is much appreciated, and I can share more information or logs if they'd help.

My camera doesn't focus. Is it a software problem or a hardware problem?

Hello, I have a problem with the Mi6 camera and I want you to help me to know if it's a software problem or hardware problem.
My problem is that my phone camera does not focus. It always seems to be in "macro" mode. I installed LineageOS 17.1 in late April and testing if everything was correct, I noticed that the camera was not focusing. But the last photo I took well (with LineageOS 16) was in mid-March, more than a month earlier. So before I put an issue on Lineage 17.1 or replace the camera module I would like to be sure what the fault is.
What did I find out? I installed the application called CPU Info and it detects 4 cameras: ID0, ID1, ID2 and ID3 (screenshot attached). ID0, ID2 and ID3 are back cameras and ID1 is the front camera. The Open Camera application allows me to select between those 4 cameras. And it turns out that ID0 is the camera that focuses on "macro", ID2 seems to focus on the whole picture in general, but with the ID3 camera the screen freezes. So ID0 is the default camera that the other applicantions are using.
I suspect that ID3 is a virtual camera that should "join" cameras ID0 and ID1 in some way. And this is what is failing. This makes sense?
Is it normal for my mobile to detect 4 cameras? Is there an application that can help me more? Any log I can review? Anything you can do before buying a new camera module?
Xiaomi MI 6 - LineageOS 17.1 - fw: fw_sagit_miui_MI6Global_V11.0.6.0.PCAMIXM - Magisk installed without any modules

I installed Lineage OS 16 and the camera failed too, so I think It's a hardware problem .

Flash Fastboot rom with MiFlash and check the camera. If it fails again it's probably a hardware issue.
Good luck, zaqm

Have you recently changed the screen or any component?
It happened to me a while ago, I still did not focus the camera, but it turns out that it is a problem that the camera block is loose, that is, the metal box where the lenses are located is loose hitting against the protective glass and blocking the function to focus.
It happened to me because the screen I replaced comes with a frame, but the new frame does not have sheets that hold the camera block and therefore causing the failure.
Try to give a few strokes to see if the block is accommodated and you notice that it already focuses again and you can be sure that that is the problem, question of fixing it.
