Rear Camera Black Screen (Front facing works) - Galaxy S II Q&A, Help & Troubleshooting

Hi
I've been asked to try and sort an issue with the rear camera (main camera) on a family members SGII (I9100P). The rear camera when activated just shows black. I have tried numerous different Kernels and different ROM's. I installed the latest 4.1.2 for the I9100P and the rear camera worked for about 20 minutes and then it went back to displaying black. The front facing camera works fine.
Any ideas on the cause of this or how to fix it?
Thanks in advance.
Regards,
Ross

Quick update. I rooted the phone using this method and now the camera works for a little while and then freezes and "Unknown error by ErrorCallback" comes up on the screen. I exit out and re-enter the camera and the screen is black, but if I then exit out and re-enter, it starts again for a very short while.

Bump - Anyone? I am 'assuming' it is software related as it works for a short while then cuts out.

Bump.

is it possible you accidentally changed some camera settings or camera mode?
Try going to the camera settings menu (bottom left corner of the camera app), scroll that menu all the way out, and pick "reset". This will reset your camera to factory settings. See if the problem still persists.
Or it could be too dark, and auto mode cannot focus. you need to engage night mode. but first try setting reset above.

My guess would be you've switched the macro function on at some point (either deliberately or accidentally) and then forgotten to switch back to auto-focus (I had the same problem with mine until I realised what it was!).
Go to Settings down in the bottom left of the camera screen, then select 'Focus Mode' and change back to 'Auto focus'.
I didnt turn anything on or off, i flashes the firmware to ke7. but it stopped working before i flashed. also i have reset the cam settings tons of times, nothing seems to work. it goes out of focus right after it starts focusing, and then the red bare thing comes up
It is obviously software issues, because its gets perfectly focussed before it goes blurry again
Hmm is it the macro mode issue that I read about?
Never heard anything like what you are describing, sorry.
Please do update this thread if you figure out the issue.
re-flash or update the camera's firmware
+1 to this problem. It's frustating.
I got the same problem. I just give the phone a tap on the back and it starts working again. Its so weird... i'm thinking my camera autofocus is dodgy/stuck
Try Settings >Applications >Manage Aplications > All > Camera > clear DATA
Or are you sure there is no dust on the Lens????? Trying wiping it clean
If both the above Dont work ... I dont you and you dont know me
bump..
have the same issue...
no focus at all in video mode.
i reset the camera setting a few times, delete all data from the camera app, still no luck.
my cam FW is :
cam fw ver : scef02
phone fw ver : tbec28
please advise as this is getting really frustrating...
many thanks.
Samsung I9100 camera focus problem
Hi,
I have the same issue as described above. Perhaps it occured just as I updated to Android version 2.3.3, not sure but could be.
Anyone found a solution to this problem?
auto focus doesn't work correctly out of the box
Hello,
Just got a brand new GSII from Sprint; awesome!! AutoFocus though is CRAZY and possessed!! it will be in focus then go out of focus... non-stop... did this from day one; Running 2.3.4 does not seem to do this with the still camera.
I'm having the same problem. I tried switching roms, going back to stock, nothing helped. Anyone having a solution? It is a software issue, because 3 days ago mine was working for like 5 min..

I had the same problem but disappeared cleaning the lens from the fingerprints and grease
I finally rooted and the flashed Galnet Miui, but then the quality of photos dropped. So I flashed another ROM, same results. So now i restored backup of my original ROM and it got better, but still nowhere near the quality of pre-root.
So I messed up camera for nothing =/
I have the same problem, with one small difference, i dropped the phone in the toilet. Got it dry, changed the camera and now I have this focus problem. In camera mod, if I touch the screen the camera will focus, but it doesn't focus from the moment I start the Camera app. So since the camera don't auto-focus by itself when I go into video mod the image is all blurry.

[Q] How to change camera resoluton to a ported rom?

I ported some rom to my device (star 9770 mtk6577) but all of them have the same problem: front camera not working. As far as i remember by the first time it worked but taking photos at 3Mpx (it should be a 0.3Mpx) but now when i switch to it the screen becomes black as the camera was covered (but it isn't) and the phone becomes slower until i switch to the main camera. The problem is still remaining running a MIUI with the same kernel so i think the problem may be there. Is it possible that the high resolution could have broke down that camera and is there any way to revive it?
EDIT
That wasn't the problem, probably the front camera is detached from the electric contacts and it don't work properly. In fact sometimes when I press on the camera it begins to work.

Sharkfin doesn't rise for taking selfie

My Reno 10x zoom phone has a strange issue. When I turn on camera it shows rear viewfinder at the same time the shark fin (front camera) pops out. But when I change to front camera for a selfie shot the shark fin closes and the screen goes black. I don't know how to fix this issue. Any help would be much appreciated.

Sounds like you've got the phone facing the wrong way!!!
Of not....then there's a software issue.
Try:
1. Turning the camera around (LOL)
Or
2. Deleting camera cache and storage
Then
3. Restarting device. Check

I did clear the cache and did software update to android 10. Still no change. With the rear camera out of the three only wide angle camera works at all the different settings. Oit doesn't switch ot the main camera or the periscope.

And there's nothing preventing it from rising? Anything stuck in the sides stopping it coming out (dirt, sand, etc)?
