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...

[Q] Epic 4g w/ Legendary Issues?! Help

Hello... I installed the latest Legendary RC with the included Samauri kernel. I started with a clean wipe. I also installed GO Launcher EX (5x4 on Homescreens).
I LOVE this rom. Very snappy. However, I'm having 2 big issues.
1. The battery indicator has been erratic especially after reboot. It will show 60%, I'll reboot or restart and it will be at 20%. Has anybody else experienced this or is there something I can do to fix it?
2. I had all my home screens setup then when I restart sometimes the screens get messed up. Sometimes I will get repeat widgets and overlapping widgets. I fix it, reboot, and it may or may not get messed up again upon restart. Because it happens on restart I do not know if this is related to the above problem or if there is an incapatibility between GO 5x4 and Legendary?
Any help would be greatly appreciated. This is my first ROM so I'm a complete noob.

Additionally, A video chat using Google Talk has a green screen for my video (the front camera)

Should I reinstall the ROM? Will that mess up any of my apps or data?

I reinstalled the ROM but I have the same issue with the Gtalk Video being solid green for my front facing camera. Any ideas?

Bueller? Bueller?

Let me ask a different question about the front facing camera not working. Is it definitely a ROM issue? I installed a different kernel and that didn't make any difference.

Should I be asking this in a different location?

Screen tearing in launcher on ics ota?

I'm on t mobile nexus with the ota 4.0.3 update running. My install process was wipe, install 2.3.6, wipe, install the ota from one of the guides on xda, reflash recovery, flash su app. I keep getting screen tearing at the bottom of my launcher, and whenever a part of the screen is supposed to get dim (eg when a popup window comes onscreen) the fade animation acts really weird (it will kind of flash/distort). Any advice? Is this a common occurrence? Should I reflash from stock or would flashing a kernel later on solve this? I kind of don't want to have to reconfigure everything again.

Made a youtube video of the problem:
The launcher will (seemingly at random) get really choppy and start to tear at the bottom of the screen. I know it's hard to make out in the video (I couldn't get my camera to focus properly) but it is tearing. It's easiest to see between 0:05 and 0:10.

bump 10char

I can't be the only one to have noticed this. I see it on both my and my friend's nexus s's.

At least you're getting it in certain situations only. I get screen tearing in the lower left corner of the display in every app that uses hardware acceleration.
Using an I9023 running stock 4.0.3.

JellyBelly ROM (CM10) Version 3 Issues

I recently installed the JellyBelly ROM v.3 (CM10) on my EVO Shift. I really appreciate the work that the devs are doing on this ROM. I am posting some bugs I encountered after running the ROM for a day. I hope this info helps make the ROM more stable and polished for the entire community. This is my way of giving back right now. Thanks for all the hard work guys!
Green Box During Boot Screen Bug - During boot the HTC screen with white background is displayed for a few seconds, then the boot animation appears. During the transition between the HTC screen and boot animation you can see the HTC screen turns into a green box and fills the upper 30% of the display for a second or two prior to the boot animation starting. This is not a critical bug, yet it may point to a larger underlying video issue in the system. If nothing else, it could give a poor first impression about the ROM quality due to graphic glitches.
Random Screen Freeze/SOD Bug - For no apparent reason the device would lock up and refuse to respond to touch input or pressing the power button. I was forced to remove the battery several times in order to reboot the device. I was unable to establish exactly what caused the lock up, but I was curious if the CPU settings and clock settings might be to blame?
Camera Green Line Bug - After I took a couple pictures I reviewed them in the Gallery app. I immediately noticed that my pictures all had a green line down the left side. I thought that perhaps the stock Camera app was to blame so I installed CameraZoom, a third party camera app as a replacement to the stock Camera app. The result was that the entire upper half of the images taken with CameraZoom app were solid green. I'm not sure if the driver or the app is to blame for this experience.
Facebook App Crash Bug - The Facebook app refused to launch without crashing for me.
I want to run this ROM as my primary ROM, but these issues, except for the Boot Screen Bug, are show stoppers for me. Keep up the great work. I look forward to version 4!

The boot animation thing happens even when there is no boot animation... All the others I have fixed except Facebook, working on that at the moment. Once that is fixed v4 will be up... Facebook seems to be taking up way more RAM than it should The camera line is caused by the 4.2 camera, I took it out and replaced it with 4.1 camera. BTW I got your message, but was unable to respond to it.

Been running this since V2 came out and have seen your issues as well. When the screen locks up I just wait for a minute or so and the current app stops and doesn't require battery pull. Can't wait for those fixes.

Thanks for the info. What was causing the phone to stop responding to input and how did you fix it? Also, do you have a complete list of outstanding bugs that have been reported so far?

Actually you got all the bugs reported except Netflix... I got Facebook working, but now wifi won't turn on
The main issue with JB on the Shift IMO is RAM dispersion, which is mainly what I am working on.

Great info! Also meant to ask, why are there two flashlight applications installed? Why is Flipboard installed by default? Seems like Flipboard is kind of an odd default app.

Because it is a work in progress (I was testing them and forgot to remove one), and flipboard works better than Facebook

Yes, but you'll soon have those issues fixed I'm sure. Looking forward to v4.

Got Facebook fixed, but I don't like how much performance I am having to give up to keep it from crashing... I'm hoping there is a perfect median, I just haven't found it yet. I have noticed quite a bit of difference between launchers also. This is my first dive into JB, so it's been a learning process. Got one more thing to try tonight.

I have had issues with the keyboard. on V3 Im not sure how it will work out with the V4. In most cases i would have to hold the . Shift button instead of just tapping it one to cap a letter. and then it resumes to lower case letters. ive also had to Hold FN to Create symbols instead of tapping just once. to make that symbol. over all it is a great rom i do have by far great expectations of it . i will re-flash once. some of those kinks are out such as the green line on the photos. as far as 4g goes i can careless about it considering the fact that i have no 4g in my local area .
As far as FB Goes i never use it ( Its a relationship killer ) xD
None the less keep up the great work on Deving the Rom .
I look forward to future updates. and maybe a keyboard fix. where it was like originally having it .
( Also random Closing of the browser . Ive had a few on V3 . But as i said im not sure what V4 will have in store for me. )

v4 is up and most of said bugs have been eliminated:sly:
You can post any v4 issues here if you change the title of the thread.

[Q] Skyrocket Camera not working properly (App is freezing/crashing)

I've been having camera issues with my Skyrocket for a while now. About 1/4 the times I start up my camera app, it will display what the camera is seeing, but none of the user interface is there. No option buttons, no focus rectangle - nothing. If I try to hit the back button, it lags out for a while and will usually (after 30+ seconds) tell me that the camera app is not responding. If I hit the Home button, it takes me back home, but opening the camera app again will still show the camera's view without the UI.
If I follow this guy's suggestion, it does work.
http://david.feinzeig.com/blog/2012...galaxy-s-ii-or-other-samsung-android-devices/
However, this process is tedious and time consuming, especially if this is happening 1/4 the times I use my camera. I use my camera a lot on my phone, and this has been a huge PITA. This might just be speculation on my part, but I don't recall having this issue before rooting my phone. I was hoping that by upgrading from Seanz ICS to [4.1.2] [UCLL3] Stock Debloat it would solve my problem, but unfortunately it hasn't.
Does anyone know of a more permanent way of preventing the camera app from crashing so frequently?

I just wanted to bump this one final time to see if anyone had any suggestions for me. I still have no clue why it's failing to boot the camera's UI sometimes, but it is extremely annoying and I would appreciate any help, suggestions, or even hypotheses at this point.

return to stock with odin and see if that cures it, wipe before and after returning to stock ics, if its still a prob then its hardware failure
edit: or an app that youre installing is interfering wth the camera, or sdcard issues

Download ICS Camera from the Play Store. Works great even when stock camera isn't. I don't know why.

I'll give those a shot and see what comes of it. Thank you for the help.
