Rear camera not working properly - One (M8) Q&A, Help & Troubleshooting

Hello, I've been having this M8 since January 2017 now.
When I got it, it had no issues. After a while, the battery, was faulty, started turning off the phone at random percentages. Got it replaced and was all okay. Now a few weeks ago, the back camera stops working. I thought the hardware was at fault, but a few days later, it works again perfectly. And now it has gone faulty again. Right now, if I take the camera and use the rear cam, it would stay black for about 5 secs and crash to home screen without any message.
The front cam works perfectly.
I've tried a RUU flash. I've tried reconnecting the camera. I've done a ROM change. I've tried safe mode. Tried opening it in landscape and in potrait. Not of any help.
What should I do guys?

So you tried an RUU flash. But what was the results? It installed properly, but still have the camera issue?

Front Facing Camera not working / causes camera app to crash

All,
I noticed yesterday when attempting to use the front facing camera that I get only a black screen, the camera app switches back to rear camera for a moment, then the app closes.
I am not sure when this became an issue as I'm not a selfie kind of guy. The rear camera continues to function just fine.
I have tried the following fixes
wipe data in the camera app
wipe user data
uninstall / reinstall camera update
boot into safe mode
uninstall / reinstall app that utilize the camera
None of the "fixes" have resolved the problem.
Does anyone have a suggestion where to head next?
Phone is S-Off, unlocked, rooted, and running the latest stock ROM.
Should I just say f-it and try a different ROM?
Thanks in advance for any advice!
Update: I flashed LeeDroid ROM this morning and the front facing camera is still not working. Looks like it could be a hardware issue...

yah, that's what it looks like. hope you have warranty.
I have the same issue. Previously when I pressed the swirly-arrows button it tried to switch then locked up and wouldn't do anything until I restarted. Now when I press the button it just spins around and nothing happens. I used catlog reader to find some errors being logged. I posted a thread about it if you're interested.

Camera not working!!!

I have started with the stock ROM, and used cm13, and even updated to the newest fully stock ROM 3.2.4 and to no avail.
The camera app either force closes or nothing shows up on screen. Every once in awhile the front camera will work, but I'll click the icon to switch to the rear camera and no effect, it just stays on fron t camera.
I've tried many third-party apps, I've tried cm camera fix, everything I can think. Clearing data and coach for the app the whole shabang.
Now I'm ordering a brand new camera module and I will see what happens. But any help and any information will be much appreciated thanks
Was it working when you bought it...what did you do to it before it broke?
it definitely seems like a hardware issue, had it been a software issue a custom rom or 3rd party camera might have resolved it and since you have tried many roms and reverted back to stock too so it doesnt look like a software issue.

Funny you should ask, because I honestly don't know when it actually started but I do remember wiping userdata so I could unencrypt my phone and thereafter was when I noticed it no longer worked. Don't know if those 2 things correlate because I flashed back to stock (which is encrypted) and still no luck
Did you solve the camera problem ???

Camera not working

Hello,
so for the past few weeks my camera hasn't been working and I finally decided to ask you guys for help.
It all started when I wanted to try RR but it kept asking for 21C modem so I quickly downloaded one and flashed it. So I checked what I needed and restored Fulmics from the nandroid backup I made, but the camera app stared to just crash and since then I pretty much don't have camera.
What I've tried till now:
Restoring to stock
Flashing Fulmics again
Replacing the camera
Still can't resolve this issue...
By restoring to stock, do you mean flashing a TOT or KDZ file?
If you have done that and still not working you have something broken in your hardware.
Is the front camera working?
I guess you have already tried a different camera app.

Sorry for the late reply. I used the kdz file. The front camera is working. The thing is that yesterday the camera worked for a few minutes just fine. It's strange.

Ummm... sounds strange... maybe your camera is partly broken, did you drop your phone or something before this problem? If so, the camera could have a bad connection to the motherboard or is about to die.

I know right? I've never dropped it. I replaced the camera so I wonder if it can somehow be a software problem...
Just wanted to bump this as I STILL have this problem...
Same issue here, was running fulmics for several months with no issue, then suddenly and out of nowhere my camera app started to fail. At first the front camera looked stretched and weird and some app buttons dissapeared such as flash, but I could still choose front or rear camera and both worked fine. Then it got worse and the button to switch cameras dissapeared completely. I tried re flashing fulmics, tried xenon rom, tried back to stock... nothing so far. I tried booting in safe mode and the camera app gives me the option to choose rear camera but when I press it the app crashes.
I hope someone can find a fix for this!

No software update inbetween? Sounds like a hardware issue, try cleaning your connections and reattaching the Camera tightly.
The camera module is extremely close to the problematic overheating chip in the G3, so it's not impossible something got messed up.
I have Exactly the same problem.. Pleaaase someone give us a solution.. Fulmics ruined our phones
I have that same problem. Resolved?
There were fulmics rum. I decided to replace it with RR rom. The rear camera did not work, the flash did not work.
I installed a different kernel but it was not resolved.
Help plsss

For a few months ago, my M30's front camera doesn't work. Sometimes the rear camera works but when I switch to front, the app freezes and then I've got to close it. I tested front camera by dialling *#0*# but it says FAILED!!
Any solution anyone?

I checked just now, it works fine. I tried various angles. Everything works fine. As I asked, it may be due to some hardware trouble or something triggering it.

I read on Samsung Community that a user with the same camera error had to go to service center and had the motherboard changed. I believe it IS a hardware issue

Yup, does sound like hardware issue. Just FYI, Samsung current charges are exorbitant, and they in some countries FORMAT whole data even for smallest of things, irrespective of hardware or software issues (f***ing idiots). So, please beware of the 2 points.

Question Poco F3 front camera problem

Hi,
I got the F3 about 3 weeks back. I have an issue with the front camera. It works for a few minutes after a reboot. Then it stops working. The camera app shows a black screen, the face unlock doesn't work. It worked fine for the first week and then suddenly it started causing this problem.
I have tried other apps, none work.
Sorry to be the bearer of bad news but this sounds like a hardware issue

Do you have check if you pass the cit test?

Yes. Passed.
The camera has started working.
Will update if the problem recurs.
Thanks a lot.
The problem recurs and CIT also fails.
Most likely a hardware issue as suggested by Robert.

Usually, hardware issue means a definitive failure. This "works/doen't work" is more appropriate for a software issue.
I have the same problem and in CIT the camera recovers and when i use the normal camera again it crashes after some seconds.
