Camera not working after Root and flashing ROM - Samsung Galaxy S7 Questions and Answers

Hello everybody,
today i bought a new Galaxy S7 (Exynos).
Becuase i had Resurrection Remix OS on my previous phone, a Galaxy S5, and since i loved it, i decided to install the S7 version.
So, my first step was to follow this guide to install TWRP and Root:
https://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770
Afterwards i flashed Resurrection Remix OS Rom. But then i discovered that the camera isnt working: As soon as im opening the camera app, the screen stays black and after some seconds either "Can't connect to camera" or "Camera has stopped" is popping into my eyes. Then i tried to install LineageOS, but the result was the same.
I found something on Google to force stop the camera app and deleting cache etc - which i did, but it didnt help.
So i flashed back the Stock Firmware (G930FXXS1DQG4) and camera worked again.
I tried again to install TWRP and the ROM afterwards, but again, camera isnt working.
Can someone help me about? I totally dont want to stick to the S7 Stock Firmware.
Thanks in advance

You probably have the Sony camera sensor, which is not working on AOSP ROMs yet.

Ah ... Well, that's some explanation. Thank you

Looks like there is a solution for the Sony sensor.
Looks like there is a solution for the Sony sensor, if I have read it right. At least for Linage OS (but I haven't installed id yet).
Unfortunately I can' t post outside links here, but look for Lineage OS BUGBASH-729 in google.
Have at look at this for information and what looks like the solution on the problem.
And read through Activity - All.

[HELP] camera freezes with custom roms

help please. the camera works fine with stock roms, but since I flashed DU official 8.1, any intention to take a photo (regardless of camera app) makes the screen freeze (not force close, it just freezes while generating the photo, and the save animation does not play, and no photo is created ) except for the nav bar back and home buttons. this happens with every custom roms I have tried after the first event. I used to think it was a matter of DU rom, but it also happens with mokee, pa, liquidsmooth, mahdi, spirit and pac. I have tried several solutions like flashing cam libs, stock cam apps, reflashing custom rom, flashing custom kernels, but the only method that makes camera apps work again is flashing stock roms through fastboot. I have an xt1032. it only happens with the back camera, photos taken with the front camera are saved as usual and the apps don't freeze. please bring a ray of light into my case, I don't know what else to try.

Go to dhacker's cyanogenmod thread and search for a zip on the last pages. It flashes the stock camera + libs and everything else needed.
I was going through the same things you are and it worked perfectly

Here you go, just flash this zip

I uploaded it for you and everyone else having this problem. Hope it works
thank you, it seems the camera works for now. it is nice that it now receives updates in spite of using a custom rom. however after flashing this zip, dalvik cache for user apps was wiped (without me performing any wipe) and then the theme engine broke. I can't install any theme apks manually, and if I try to install one from the playstore, I get an error notification and the " uninstall" button becomes "install" again. also, themes installed manually appear to be of 0.00MB. I will reflash my current rom and post the results later.
EDIT: clean reflashed and immediately flashed the cam+libs zip. everything works thanks a lot!!

Camera mods on Jesse's Note7 Port for G930F!!

Hello all!
I have recently installed Jesse's N7 port on my G930F with Samsung ISP (camera sensor).
I noticed that other users complained about camera mods not working at all. In my case, everything works pretty well and the camera quality is also impressive! I think it is because I flashed (zeroCamera_s7_v5_exynos) mod after installing the rom. Maybe that would help!
BTW, I have a question. When I was flashing the new version 1.2 of the same rom, the installation process took only 5 seconds (it took 2 mins with the previous 1.1 version). After that, the phone did not pass S7 logo! luckily I had a backup of everything, but now I can not flash the updated version. Any help please?

Camera and Flashlight error in LineageOS 17.1 osprey

So I had installed the latest lineageOS version ( 17.1, android 10, osprey moto g3) from the official website and flashed it correctly, but after some time, I noticed that the torch icon was greyed out in the status bar and any camera app won't work.
The app showed- "Camera stopped working"
Cleared cache, app info, rebooted the phone but nothing seemed to work.
I thought that flashing the ROM again would fix it, I redownloaded the latest lineageOS version, new GApps, and flashed it in the correct way( first wipe then flash), but the issue came back after a few reboots.
So I rebooted again and it got fixed, but I think the issue might spring back.
Is there any fix for this?

Hello members,
Last week i'v also installed the latest lineageOS version ( 17.1, android 10) Gapps nano, on my Samsung A3 2017. With the TWRP tool., Nice ROM!
Unfortionally with the same issue as above, Samsung and other camera app's very often not working, need to reboot to fix that.
The flashlight does not work either then, and much more irritating BlueTooth not working anymore, my A3 always had perfect connection with my Parrot carkit CK3100.
I'v found in several forum some workarounds for this but these do not solve the issues long enough.
But the issues are also found in older releases from LineageOS.
Will there be a update for these mentioned 3 issues?
If not, i need to install another ROM which is not based on LineageOS.
The Cam and BT must work without any problems.
Thank you very much.
Frank.

Ressurection Remix on A8

Hello everyone,
I am creating this post because I would like to know if someone has already installed Ressurection Remix on a Galaxy A8 ?
I saw some tutorials that are explaining this is possible,but when I go to the Ressurection Remix official download page, I cannot find which file is specific to the galaxy A8. Actually, I have some difficulties to understand the files names : Raphael, Sakura, Jason,... Are theses names code names for différents phones ?
I may add that the bootloader of my phone is unlocked, and I am using TWRP to flash zip files.
I didn't treblelize my phone thought.
If you have some other custom rom suggestions, please do not hesitate to advise me.
You can install RR through GSI, by this link
You will have to trebelize your device
Because it's a gsi android 10, you can use vendor quack
Treble Guide
Vendor Quack
Thanks for your reply. Yes I saw that it was possible to treblelize the phone, to install other rom like the very famous lineage os.
But I am little bit hesitant about this procedure : is everything working well with the phone after a treblelization ? Has anyone tried this method?

Treblizing the phone itself does not cause any problem rather it enables you to install different GSIs. Regarding GSIs, each have there own bugs and you have to find them on the GSI thread if available or if they have telegram or github support.
Hey, just made an account to respond to this as I just discovered there are per-device pages on these forums and saw this post, I have done exactly that and been running it for 2+ years now, so far I have had no majour problems wih it, the only majour caviat is that after trebblimg it and installing resurrection remix It seems to freeze when trying to display the charging animation if the phone is off and it plugged in, it still charges without any problems, tho to boot it when in this situation you need to force shut it down using the volume_down + lock buttons and then immidiately after use volume_up + lock buttons to boot into recovery, then you can boot to the normal system from there, I have a TWRP recovery but I think the stock one also allows to resume booting the normal system.
In these last months I had a few weird bugs like the screen brightness beeing locked to automatic but that went away after a reboot and only happened 1 time.
I also installed magisk and a few other small tweaks and things and everything works great, also all resurrection remix customization options.
Actually in the last few months something broke because the safetynet checks fail for the ctsProfile, (most apps like my banking app tho still work fine by using magisk hide (i think it's because the safetynet basicIntegrity check still succeds) and the update page seems also broken (tho no idea about when this broke exactly as I haven't checked it in years), everything else is still fine tho, I might try re-flashing it to update to the new majour resurrection remix when i have time and the will to backup and move everything, something could have corrupted or maybe an update broke it, no idea.
My phone reports resurrection remix 7.0.2 and Android 9.
Hope this is still helpful.

Stock camera app not working

Hello,
I got a big issue on my Mi 10 Ultra, the stock camera is not wanting to work anymore.
It's black only and then refuses to launch (see screenshot attached).
I've tried third party apps but quality is not as good and I can't use all the camera modules. I've bought the 10 Ultra for it's cameras and really want to keep using it. (I do a lot of macrophotography and the 10 Ultra is amazing for this but only on the wide angle module.)
Did someone encountered the same issue ?
I've tried installing GCam but I do not managed to install apks. Theres an issue during the package analysis... (I've tried all GCam apks I could find here.)
I'm on stock EU OS with TWRP and I just activated root to try to solve the issue.
Sorry for bad english and french screenshots
EDIT: Every camera is working in the CIT hardware tests, I think it's software but I resetted the phone and nothing changed.

stock EU OS ?
you mean Xiaomi Eu ROM?
If the code name is CAS,there are chinesse firmware only.
maybe try that
Use this tool https://forum.xda-developers.com/t/flash-tool-guide-use-xiaomi-flash-tool.4262425/
Unroot before and dont relock the bootloader.
Thanks for the answer

I got the Xiaomi.EU ROM as it was shipped with. It has a TWRP recovery from when I rooted it and got Magisk installed.
My MIUI 12 version is V12.0.15.0.QJJCNXM (stable).

I understand this is a tutorial to change my ROM, which is not what I'm searching for as the ROM works really well. Plus I only see the CAS on this thread's links which is the chinese ROM.
Not sure what you meant.
My bootloader was locked all the time, I just unlocked it during my testing but it did not change anything.

Now in the tests, my 5x telephoto camera does not respond, so I think it's an hardware issue, but I don't think the camera is broken so I'd like to found people with the same experience.
I don't think changing the recovery will solve the problem.
Plus I like having TWRP

Flash this rom to be sure
Mi 10 Ultra ChinaStableFastbootV13.0.4.0.SJJCNXM
Just to be sure of something, I did a test. Thanks for answering all my messages but what I need and want now is info or a way to debunk the issue.
I wont flash a ROM in a language I don't understand on the phone I use every day just to test something.
I already tried resetting the phone (including dalvik cache iirc) and it did not change anything.
Plus I would need a PC and a flashing tool, this would take a lot of time...
Finally, the issue did not came with a ROM change, the actual ROM is stable.
Edit : I changed the camera module, everything works perfectly
According to my repair shop, Xiaomis are just unreliable.
