[Q] Camera not working on non stock ROM

I have a known camera issue in which I cannot solve.
My camera does not work. Any app that tries to get to the camera fails.
I know that is not an hardware issue because on stock ROM the camera works.
Crash report:
java.lang.RuntimeException: startPreview failed
at android.hardware.Camera.startPreview(Native Method)
at com.android.camera.AndroidCameraManagerImpl$CameraHandler.handleMessage(AndroidCameraManagerImpl.java:261)

NOTES ַ& UPDATES
- I updated my firmware to NE4 so I cant install CM11
- I noticed that on CWM recovery its asks to ROOT my phone if I dont have one. This ROOT makes to phone to not detect the camera even on stock ROM.
- I used S3Rx_UCUFNE4_AROMA_11-9-14 to install the stock ROM. The camera wont work until I removed the KNOX app.
- I have tried to install ROM cm-10.2.1-d2att_for_NE4 and its the same problem
- Installing different kernels make my phone stuck on bootloop.
- The camera worked for one time only on CM10 after enabling " temp unroot" and than remove it in superuser app. But after this its not working.
Here is that things that I have tried:
- I checked to camera with no SD card so that gallery is empty.
- I updated my firmware from UCUFNE4 to UCUFNE4.
- I have installed different camera apps.

IDEAS
I think that the problem is with the kernel or something with the ROOT.
Any room expect the stock one have broken camera.
I WILL GIVE BIG DONATION TO THE ONE WHO WILL SOLVE THIS ISSUE

There is a corrupt image or video file in your gallery that is preventing the camera from connecting. Look in your gallery for any recent files that just show a black square for their thumbnail and then delete them.
After that, clear data for your camera app and maybe even restart your phone just to be safe. It should work.

Have you tried to revert all OS updates and flash original stock with odin and then root and install cm11 ?

I tried various of the recommended fixes , nothing worked for me, but installing the nexus camera from the google play somehow fixed the problem and my camera works again

Facebook messenger freezing on front camera

Hi,
I have recently flashed a new ROM onto my SMT700 which was mostly successful however I am having a problem where the camera freezes as soon as the call starts. I am also unable to take live photos using the app. No other app is having this problem. I have tried using older versions of the messenger app and that seems to have fixed the issue with live photos however the video call problem is still there. I have tried reflashing the ROM and even downgrading to a 6.0 ROM (current is a 7.0) but nothing has fixed this issue. I cannot go back to stock since my backup is broken (I cannot see any partition options in twrp when attempting to restore) so I am currently stuck with this problem. I am also unable to download the stock firmware as every browser I have keeps failing to download it from ant site (SamMobile etc). Any help would be appreciated

Camera Playground feature not working?

Does anyone have this problem? Updated today to the new camera version and discovered the new playground option does not work, when launched it just sits there and does nothing. Quitting the app causes all subsequent launches of the camera app to display no images on screen through the lens just a big block of grey. Only a hardboot will restore the camera functions. I did an uninstall of all updates to go back to the November system version and the Arc Core function reacts the same way. Anybody have any similar experience?
Running the November security updates with stock kernel and only Magisk 17.3 applied.

I installed the new camera today - Playground works just fine. No issues at all. I am running a custom kernel - not sure if that matters - (Franken Kernel 5.1) and all is good.... sorry you are having issues - have you tried to clear cache/Data on camera APK to see if that helps?
Good Luck...

Tried all of that, even went so far as to do a complete factory reset and wipe to see if it would work on a completely stock system but still no go. Maybe I have a bad AR chip or something.

Reapply your animation serrings
If Google playground has stopped working, active your animation settings on your phone. This fixed it for me!!

Issues with ARCore related apps

Wondering if anyone here may have a suggestion. For the past few months I have not been able to use anything ARCore related on my Pixel 3XL. Camera modes that use it (slow mo and playground), Measure app, etc. all crash immediately. The camera functions normally otherwise. I first noticed it when I went into the Beta program for Q, but for all I know it was happening before.
Things i have tried so far:
Reboot
Factory Reset
Complete re-install of Android 10
Complete re-install of Android 10 without restoring backups
Complete re-install of Android P without restoring backups
The only thing I can think is that I replaced a broken screen. Could I have damaged something while I had the phone open that is causing ARCore failures?

Latest OTA Update to Pixel 3a killed the camera!

I accepted the latest OTA update for lineage. After the reboot my camera app shows a black screen for the main camera and crashes after a few seconds.
What I've tried:
Messing with the camera app, permissions etc.
Trying other camera apps, same problem.
Rebooting.
Since I wanted to see what grapheneOS was like I tried installing that.
Same problem....?
Okay so then I thought they might be sharing the same camera driver. So I installed...
The latest Google factory image.
Then I tried reverting to Android 11 (everything was 12 before)
Main camera is still dead. Selfie camera works.
