Camera black screen

I get a black screen in Camera, Camcorder,
I'm using the XTv2MIUI ROM.
Anybody can help to fix it. Have install back to the 2.1 stock rom, format the SD ,deleted the 3rd party cam apps. Still can't fix it.

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...

[Solved]
Finally solved by replaced the motherbroad from service center.
Thanks all the comments provided!!!

faux kernal camera crashes?

It is a known issue that faux kernal may cause the phone to freeze up, requiring battery pull and reboot when you press the power button to turn the screen off while using the camera app.
Do others also experience this if the screen turns off on its own due to inactivity time with camera app running on screen? What about if camera app is in background when screen goes or is turned off?
Does faux kernal need a camera fix similar to the one for bricked?
Thanks.

Yes buddy its a known issue that faux kernel freeze phone manytimes,but camera crashes fix is not available,have u wiped cache and dalvik cache before flashing kernel ?

I did superwipe when I installed the kernal as part of the ARHD ROM so I think I am covered there.
My issues seem to occur only if I use the camera app. I was intending to ask if the scenarios I described in the second paragraph of post 1 are part of this issue, when it is experienced by others.

Any comments about whether these scenarios are considered part of the known problem?

Bump.......

Yes , you must use back button to exit the camera so that it is not running in the background. It is a conflict of faux's extreme power management, and htc's camera power management. It probably won't be fixed. Just remember to use back button to leave Camera app. Also, no need to pull battery, just press power+up+down volume and hold all three and after 5 seconds or so, it should restart.

Camera app won't start from home screen.

I'm having an issue (sometimes), when I tap on camera icon at home screen the camera app flashes for a moment and I'm back on home screen. I've tried many times tapping on the icon nonstop, it just quits instantly.
But when I start camera app from all programs list or lock screen, it always starts fine.
Anyone experienced this?
What could cause this?

i had the same problem the other day .. my camera app would not open! it just did exactly what you described .. i even closed all the recent apps to see if it was low memory.. it still didn't work.. but a simple restart of the phone cured it ... not really sure what happened but hasn't happened again yet knock on wood

its probably just android being android .. hahaha no but seriously .. prob just a memory glitch or something

Reboot usually cure most bugs for while, but with this particular one it's interesting, that camera would start if started from lock screen or all apps list after it wouldn't start from home screen. Once it started it then starts fine frome homescreen too.
Very strange.

So yea the camera been acting up a lot lately ... It has happened 3 more times since I last posted on this thread..I have to reboot for it to start working again ... Its soon annoying!!! I missed the moments I needed to capture a pic because of it!! Not sure what the culprit is

Just remove it from your dock and place back...that is alot easier than rebooting and should work fine.

My girlfriend's camera app wouldn't start from the home screen or the app menu. I had to connect it to my computer and rename the DCIM folder and reboot the phone before it worked again.

Upgraded to ruu 1.85 - still same problem.

Same issue here. I will try and open the camera app up and it immediately crashes. It doesn't even really open, it just flashes the camera buttons and goes back to the home screen. It has happened to me at least 10 times since I've purchased the phone.
Restart is the only thing that alleviates the issue. Any ideas? Let's keep this going because it is pretty annoying to have to restart the phone just to use the camera.

But when this happens, have you tried any of these:
1) open app list (middle soft button) and then start the camera from home screen
2) start camera from app list
3) lock the phone with power button, and drag camera icon to the unlock circle.
For me either of the above fix the problem, never had to do reboot...

I posed this in a similar thread in the general section, here is a video of it happening.

Moving out of the dock had no effect, Instagram can still use the camera hardware, but the stock camera app cannot, i wonder if it has ties with the image sense chip and is on all the time and crashes due to something....

I'm also getting this problem. It only happened once in a while at first but has now gradually gotten worse and worse. Now I can't take any pictures with my One X. Even rebooting the phone doesn't fix it. It's funny that the Instagram camera still works perfectly fine though.

[Q] Camera crashing

Hi,
Since last week my camera didn't work well anymore. I used to have no problems but since somewhere last week, my camera would crash my whole phone upon starting. This was with ARHD 6.6.4. Then I flashed 6.6.7, and the problem was still present. So I cleared cache and app data, and still, no working camera.
Yesterday I flashed OrDroid 9.0.0, hoping this would clear the problem, but it didn't. When I click the camera-app (camcorder as well) my phone hangs, and about a minute later reboots itself. When clicking main camera in Z-devicetest the same happens. Using the mirror-app, my phone keeps working and gives a clear image from the front camera.
Any advices?

Well, today my camera worked several times... But I cannot get it running again. I tried lots of different things, wifi on/off, airplane mode on/off, bt on/off, full battery, on wall charger...
I'm afraid it might be a hardware malfunction. Can anybody give some advice?

I used to have a camera problem it used to crash when I opened it. Someone told me to uncheck face detection on the camera settings and it worked. You can try that

I don't think it's a Rom issue, did you uncheck face detection ? If it's the Rom that should do the trick. I'm running ordroid 9.0.0 and I have no problems with the camera. Make sure you uncheck face detection, if it's still giving you trouble it could be a different issue. Check your settings. Could be a problem in settings. This is known to happen if face detection is on. So uncheck it and let us know if that did the trick. Hope this helps. Best wishes!

Well, I thought I found it, but it wasn't the battery. When the batt is full, or nearly full, I haven't had any problems, but when ~<80% my phone just crashes and hangs or reboots...
I did uncheck face recognition and geotagging when it worked, but this hasn't fixed anything.

Are you on a custom kernel or not? I have experienced flashing different roms affects the camera as well.

Bump
Same issue on several different ROMS (Sense and Senseless). Camera will work for a while then freeze and crash to the home screen OR occasionally crash and reboot. This also happens with other camera apps, not just the stock app. If I don't find a solution soon I am going back to the stock ROM.

Just as sudden as the problems appeared, they disappeared... The camera functioned for about 2/3 weeks without any problems, but now last week, all of a sudden, it started crashing my phone again whenever I start the camera app...

Camera broken

I've run into a problem with my camera on the sensation.
Whenever I try to open the app the screen just dimms (slowly but can still interact with it) and then pops back to original settings, the camera itself never starts.
This happened to me on the viper roms (1.1.0 and the new 1.2.0) both with and without camera HQ mods.
tried everything from clean install with full wipe to fixing permissions.
I truly hope it isn't something hardware related.

Absolutely nobody who know3s anything about this problem?
I get an pop up saying "Camera Open Error" "starten Camera mislukt" in dutch
The front camera also seems to have given up doing anything but black screen (tested via mirror app)

I have a problem with my Camera on my sensation taking black pics only camera app I have found to work is Fast Burst Camera. I have tried about 20 different camera apps. Even tried going back to standard ruu

Try posted in the ViperS thread, you'd most likely get a reply there. I've never had anything like that happen to me before.
