Wow so even after flashing back to stock you're still getting black screen? I've seen the black screen a few times with miui but not everytime. I was hoping it would be fixed with the final v5.
thats weird. the first time a flashed Miui I had that same problem. I just reflashed the same rom and the problem went away. I have never carried the black screen through multiple roms.
Even I flash back to the stock rom by RSD the black screen can't fixed. I already replaced the camera module but not fixed.
Do you use autokiller memory optimizer? I got black screens when I set it above strict. If you do maybe youd want to lower those settings.
I didn't install the auto killer, But even i flash back to 2.1 stock rom without any tweak apps,it still can't fixed the black screen
Hmm, same issue in several ROMs, sounds like an hardware error.
I have found the following in Loyat Forum:

Help! My camera shutter suddenly closed up and can't open anymore. Is this normal or my phone is screwed?
This is a known issue for xt720. Not all of them though but quite a number have experienced it already where the shutter just completely shut. There's nothing much can be done other than sending it back for warranty... OR you can try this trick. Get a magnet and put its South field close to the shutter. Apparently it will open up. Not sure how true is this but yea.... better than dismantle the whole phone just to find out you really screw the phone up for good...
Maybe this could help...

Hello all,
I'm hoping someone an help with this.
I have already asked a few people, but no-one has been able to solve it just yet. I have faith though.
No matter which ROM I use (was using Vegan initially, then tried TnT Lite and even the stock TnT) when I try to use the camera it seems to "crash". The app loads, and I can interact with the app, but the camera screen seems to crash (colored lines for a split second, then nothing) then goes black. I can still change settings in the camera (such as change to video etc) but the camera screen is just black. When I click the shutter button to take picture, the picture appears at the top right in the little box but is just a green square.
Anyone any ideas?
Does it sound like a software issue? Or hardware?
I'm really hoping software as I don't want my tab to be broken.
I have not tried an nvflash yet, but probably going to do that tonight and fully reset it. Might that help?
Thanks in advance!
Mine was doing something like this. I found out with mine that when I opened the case, the camera had popped out of it's spot and wasn't pointing out the keyhole.
Is your camera locking up (No pre-view picture)?
When I select the camera icon, I see the camera menu in the lower part of the screen and I can even take pictures, however I see a black image instead of the pre-view photo on the screen. This issue goes away by soft resetting the phone; however it usually comes back after few days and the only way to see the pre-view image is by resetting the phone. The strange part is that the camera can actually take pictures but I cannot see the photo before taking it. Have you heard of this issue? The phone works just fine otherwise and I like it a lot.
Thanks,

Are you running stock?
I can't speak for whatever potential issues might be caused by any of the custom roms in circulation, but on a stock phone, obviously it shouldn't be doing that.
I can't imagine what hardware issue would produce intermittent preview-ability that's temporarily remedied by a soft reset, yet still manages to capture the photo itself, but there's a first time for everything.

My stock camera application (and Camera360) and camcorder applications both exhibit this behavior. A soft-reset of the device usually temporarily resolves the issue (i.e. allows me to use the camera for a short period of time). However, after my phone has been on for a while any app that uses the camera just locks up (eventually have to force close or soft-reset).
It is rather annoying. The only information I found seems to indicate that there may be an issue with the API within FroYo itself. Hopefully when we get the update to GingerBread the problem will resolve itself.
I also read something else about something to do with an LED widget that caused someone problems but I'm not using any LED widgets, so I'm not sure what that's referring to.
Hopefully there's a fix out there somewhere or we get the 2.3 update soonish.

Hmmm...
This is the first thread I've come across that brings up this problem.
My stock (rooted) phone, my mom's stock phone, and my dad's stock phone have never encountered an issue like this, but then again, maybe we were the three lucky ones...
EDIT:
That's not to say you guys are crazy... maybe we just haven't had the right combo of circumstances to expose the problem/bug on our phones.
Now that I think more about it, I did have an issue when I ran barcode scanner once, about a month ago. That of course uses the camera. As soon as it identified the barcode, and I pressed the 'search web' button, it just froze (image still visible), but the back key/screen input was unresponsive. The only thing that worked was the home button, which, instead of going to the home screen, displayed the screen you see when you are about to end a call with someone on your phone. Thing is, I hadn't made a single call that day. That screen was also unresponsive, but when I pushed the home button again, it finally got to the home screen.
I then went into manage apps in settings and FC'd barcode scanner and the dialer/phone, just in case. I even uninstalled barcode scanner because I thought it might have a phone-specific bug that I didn't want to deal with.
I don't know if there's any correlation between the yours/OP's issue, but it sounds like it's ****ed up in a similar way. FWIW.

I think I managed to fix mine by wiping my dalvik cache. On the downside, my current drain used to be around 5 when my phone was in standby and now it is around 45. On the upside, I haven't had a problem with the camera or camcorder since then.

Mine ended up being a hardware issue. Phone was exchanged with at&t. Haven't had an issue with the camera since.
Just wanted to update for the OP.

Hi,
I have this wierd problem with my sensation. I found out that if i have my camera on and it falls a sleep it wont unlock any more. no ring nothing.buttons glow but a solid black screen. The only way out is a battery pull.
It's with photo camera and video camera mode. no other apps suffer fom this.
I've tried other roms but nothing. I currently run ARHD 3.6.7
I found out on accident but it is realy annoying me now
Any of u with the same problem or ideas?
known issue with kernel. not sure which kernels. try keepscreen app to keep screen awake if using camera so it doesnt freeze
https://market.android.com/details?id=com.tni.KeepScreenLite&hl=en
Yeah, it's bricked kernel. Doesn't matter what version you use, it seems to keep on happening randomly.

Hi,
Go into Bricked Kernel post, there is a .zip file called, CAM-FIX.zip
Flash that, magic will happen =]
Thanks guys, I've all ready flashed an other kernel and it works all fine now.
CAM-FIX.zip on the other hand is only for sense 3.5 and I really prefer sense 3.0
The camfix patch is so the camera can even function in the first place, it does not fix this issue. Without the camfix, if you try to use the camera the screen just goes black and the phone freezes. This issue however is an intermittent one, where sometimes when you exit the camera you get the black screen and freeze. Doesn't happen all the time, but it's definitely the kernel at fault.
To the OP, if in your case it's only happening once the screen times out, you could always use tasker to make it not timeout when using that app?

Hey guys ever since I got my nexus 5, randomly my camera app just don't load up the camera. I open the app, and its just black. Sometimes, it'll show a green screen with graphical defect lines all over the place. I use snapchat a lot too, and snap chat will give me an error saying to restart the app because the camera failed. But once I reboot the camera works all over again. Its just annoying because sometimes I really want to take a picture but it just doesn't open up and I have to wait for it to reboot, then take it. It did this on stock, so I rooted it and flashed Franco's kernel on the stock rom to see if that would fix it. I still get the same problem. Is this normal or do I just have a defective phone? I feel like something inside my phone is loose when I shake it, holding the bottons so I know those aren't the reason.

I'm facing an issue with my camera which I couldn't find anything about via a web search. So I would like to know if anyone experienced something similar?
I'm running the stock rom and didn't tinker with the phone.
Since yesterday my rear camera is really slow an only slowing blurred images. The whole phone seems to be running really slow and unable to handle the data. Switching to the front camera takes ages but once it's active it's working normally.
If I try to use the camera several times I end up with a black preview image. A reboot returns the camera to the previous laggy state.
Changing to a different camera app yields the same behavior. Could be an issue with the latest patch for Android 12 I i installed around the same time or my hardware is fried...

I would try a system reset if possible, I know its a pain but if it works problem solved, You could also try going back to a different build via android flash tool , just a couple of ideas although extreme ,would narrow it down even more to a hardware issue over corrupt software. Hth

I feared that I would have to do this. Factory reset and flashing an older version didn't help.
Now I can hear that something is moving inside when I shake the phone. Time to crack it open and have a look.
Thanks for the suggestions.
