[Q] Camera Shows Black Screen - Galaxy S 4 Q&A, Help & Troubleshooting

Hi,
I have a Galaxy S4 I9505 device. I am running the Imperium ROM 7.0 (i.e. Lollipop).
All this time the Camera application was working just fine. But now from some days when ever i open up the Camera application (Rear Camera) i noticed that the screen showed up Green lines on the screen and then the camera application stopped functioning. The app just used to hang and do absolutely nothing.
And now when I open the camera application the screen is completely dark showing absolutely nothing and doing absolutely nothing.
Solutions that I have tried are as follows:
1. I cleared all the Camera Application cache and it did not help.
2. I Cleared Cache and Dalvik Cache but even that did not help.
3. Tried 2 different ROMS, a. Stock ROM and b. AOSP ROM and found the same camera behaviour.
The front camera is working absolutely fine though.
Any suggestions? I now believe that the Camera Module is dead.
If so has anyone of you replaced your camera module, and would you mind sharing your success story?
Thanks

Seeing a few posts like this
There are quite a few posts like this recently. I tried swapping for a known good camera module and it did not fix my problem. Either this is related to some type of software update from google, or our motherboards are going bad.

rear of camera galaxy s4

Good morning and happy Sunday to all,
after the upgrade via OTA to version 4.4.2 kitkat galaxy s4 rear of the camera no longer works, or has worked better in a month 3 times. I state that I have performed a hard reset before and after upgrading. I tried to install (uninstall ÀThen) also third-party applications to see if it worked in this case but nulla.Ho tried to clear the cache but nothing. On the rare times that worked I noticed that opened handling the camera, but the screen remained black, if I tried to activate the front camera and it worked if I tried to reactivate the rear sometimes worked but all with a lag to be frightening. I do not think it is a hardware problem but software. The'm trying them all but I can not get it to work; another proof that I have done is to use the qrcode reader but nothing works even with quell'app.
I thank those who can give me a hand.

greetings to all

Camera Problem: autofocus reacts only after longer rest

Got a new Note 4 SM-N910C after I replaced my old, as it had display issues (same model). Old and new phone are running 5.0.1., both are rooted. I restored all apps and data from the old phone on the new via Titanium-Backup.
When I open the carema app, or ANY other camera app on the new phone, it won't focus for approximateli 10-15 seconds - afterwards autofocus works snappy and accurately. When I close the camera app and reopen it, sometimes the autofocus reacts immediately, sometimes I have to wait again. After a longer period in which i did not use the camera, the initial lag always occurs.
Same issue when I use the test mode (#0# - Mega cam). In compairison the old model always works perfectly!
Resetting the camera app does not fix the issue. "Shaking" the phone does not fix the issue.
Does anyone know that issue, does anyone hab a suggestion how to solve the problem. I don't know whether this is a hardware (stuck af-motor??) or a software problem.
I thank you for every answer and suggestion in advance.
Are you on the stock ROM now?
Yes, everythin is stock.. just rooted via CF autoroot..
Did you have this problem before you rooted the device?

It's a hardware problem, the camera lens abit loose. Some tried shaking it but only a temporary fix. Bring it to Samsung Service Centre for repair (if still have warranty). Mine had that problem and was fixed by Samsung.
Update:
I restored the device's factory settings, i.e. Recovery - Full Wipe, and flashed the Lollipop 5.0.1. stock rom via Odin. I did not not restore the camera app usting Titanium Backup.
The error still exists. Shaking the device causes no improvement at all and there are no strange noises during focusing detectable. I suspect that it is therefore definitely not a hardware failure.
.. Once again the error description:
If I do not use the camera for some minutes and open any camera app (e.g. native app, instagram, PS-express, whatsapp, Google Kamera, camera pro and also in the test mode (# 0 # - Mega Cam)) the picture is totally blurry and the focus seems to stay in the macro focus. When I try to set the focus point by touching the screen, the focus indicator appears but the focus does not change for approximately 10 seconds (again, in all camera modes and camera apps). After this "initial lag" the camera works perfectly fine. When I close my camera and open it after a short time, it focuses immediately. When I close my camera and open it after a longer time, initial lag occurs again.
This is extremely annoying.
I suspect that the system deactivates the camera ("deep sleep") so when opening the camera a full "initialization" (i.e. error checking, etc.??) is done every time. According to the Application Manager however, the camera app is active and uses the system's Ram when the lag occurs!
Can anyone - under 5.0.1. - confirm this behavior?
Again, I am very grateful for any kind of help and suggestions!
How difficult is replacing the camera? Is it simple?

"Can't connect to camera" problem in my xt1562. HELP!!!

I recently got Aosp Extended and for first two days everything was good, But then my rear camera as well as my flash stopped working.
Flash is also not working...unable to use torch. But front camera is working fine.
I have tried restarting many times and clean cache and data of camera app too..but still nothing. I also opened camera in safe mode but then also it wasn't working.
Plzz.....help me out!

Camera not focusing???

Today in the morning the camera was working just fine, but suddenly the app crashed. And when I started it again all was blurry, and the focus was not working anymore. I tried to clean the app cache, do a factory reset and I even flashed 3 different ROMS and the problem was not solved. Is there anything I can do?
Mine has had issues since new, here is what I do, try at your own risk. Open the camera app and give a good tap on the top of the phone (obviously not too hard). I think the cameras physical hardware sticks sometimes.

Camera Error

Hey y'all, I got the G6 yesterday and had a camera related question. This is a brand new device, fully updated, and when I go to open the camera, a message pops up saying "Camera Error: Camera Unavailable." Does anyone know how I can fix this?
This seems like an app error because the camera works well on Facebook and Snapchat.
settings -apps-camera -clear cache and date reboot-try!
If not working.....if not working.?.RMA
I already did that and I get the same error. I find this odd.
I was wrong. Both Snapchat and Facebook switch between the single and dual lense back cameras. They do not switch to the front camera.

I have the same issue with my LG G6. Have you fixed yours?
I got a new one, only way to fix it.
Im having the same issue after a screen replacement. The people who replaced the screen even boight a new front camera and replaced it with no luck. Also, the screenshot button for the bottom bar is conpletely missing which i find very odd.
That error seems to be the camera unpluged
I mean the phone is made of connections between hardware and the camera is not connected , its an hardware problem that is fixed by open the phone and plug jt in

I have the same issue with my phone. I replaced the cameras and it still gets the error; however, it does come on when I use a barcode reader...?
I also have the same issue (lg g6 - android 9)
When i open stock app for camera i get error "Camera unavailable".
But with other camera apps like Gcam or Open Camera, it works fine.
I flashed with new rom, but the error is still there.
Any ideas???
- i flashed with Android 9... not solved
- i flashed with Android 8... not solved
Hardware problem?
in that case why camera works fine with any other application, except stock?
Software problem?
it should have been solved after flashing two original roms (8 & 9).
The only explanation i can think is that there is hardware problem with 1 of the 2 camera. And maybe with the wide one. And maybe that's why it is not working with stock app. Maybe other camera apps don't require both camera's (normal and wide lens) to be working.
