[Q] Camera Problem: Black Preview, Crashes, and Green Screen Pictures - Android Q&A, Help & Troubleshooting

Hello xda community!
History: Yesterday I bought a jailbroken LG p990 off craigslist. All seemed fine, I could tell the guy had opened it up, but it was put back together nicely, no scratches - basically out of the box.
Problem: When I got home, I tried the camera app, but it kept crashing and timing out. On occasions I could get past the crash but the camera preview was black, and when I took a picture it would just capture a green screen. Now my first inclination was that the camera was broken, but the behavior from the app it's self is puzzling. When I get past the crash, it runs slow is delayed and just does not work properly at all. So what I am wondering is if this can be caused by faulty frimware/kernel after the jailbreak.
My Troubleshooting: I am new to rooting/jailbreaking/rom/kernel flashing so I spent about 6 hours learning as much as I could yesterday. After alot of reading, I figured a flash of the rom/kernel might reset the firmware for the camera app: (similar problem: http://forum.xda-developers.com/showthread.php?t=1841750). Got my self familiar with CWM and flashed a few different ROMs and Kernals onto the phone to no avail. (Dominationm, Cyanogenmod 7).
Other Options: Since I am so new to ROM/Kernel flashing, I may have not chosen the right flash - so I am wondering what might work (if this is the case). Another reason im guessing this isnt working is that when the guy put the phone back together, he didn't connect the camera properly. (I know enough to take a phone apart and put it back together so thats my next venture). *OR* the camera is just broken and I got scammed.
What I need help with from the XDA community: Could someone venture a reason as to why this might be happening? Can a camera's firmware break after jailbreaking or rooting? Is there a ROM/Kernel that can fix this issue or even a patch?
*Interesting link on a patch for similar camera issue with 4.0.4 non stock kernels*: http://forum.xda-developers.com/showthread.php?t=1772931
Phone Info:
Model: LG Optimus 2x

Touch screen glitches.. VERY ANNOYING. Insight anyone??

So here is goes. . Phone has been running great (unlocked). I was running ORFR 2.3.4 (with ram fix) and was on Cherry rom. Its been running steady for about a month or so, and now Im getting these glitches. When Im typing a text message the letter q keeps coming up. When I open up the multitouch app (this rom has the multitouch hack) it will randomly show something touching the top left corner. Kind of like someone is pressing that part of the screen. Then it will go away and will be fine, then it will show up again. I have removed the case, screen protector, etc.etc. Plus I have never dropped the phone. Its been in a Otterbox case since the day it was born.
I dropped the multitouch to 8 instead of 10 thinking that was the issue but it was still doing it. So I reflashed the rom (through cmw) and its still doing it. Tried the 7h3 D/\k rom and its no better. Just have the one bar issue.. great lol.
Do you think going through the reflashing process for the ORFR 2.3.4 should fix the issue? Im starting to think its a hardware issue which is not gonna be good.
Any help will be greatly appreciated!
Sounds like its hardware issue.
I voided my warranty.
Gingerbread Issue
I am having the same problem on Froyo everything worked fine once Gingerbread update came out I know have the q appearing when typing a text as well as random screen freezing. Also if I reboot its fine for a couple of days and then it happens again. If you google gingerbread screen freezes you will see everybody is having this problem. Thanks

Some custom kernels have a problem with the highest resolution for the front camera due to memory allocation. Go to settings / applications / all and clear data for camera.
Load up the camera switch to the front one and check its working.
If it is don't select the highest resolution for the front camera use the middle one.
If that doesn't work maybe another problem.
Please state what rom and kernel versions you are running, more info the better.

Appears to be a S3 problem specificically, camera failure problems. Google ' galaxy s3 camera failed ' and there are numerous reports ranging.
from only a day old out of the box to a couple of weeks. Some reports of total failure, some hardware restart temporarily fixed, some app sharing hardware such as skype hogging the camera.
I think Verizon in the US are saying return for replacement..
Hope this helps.
Having the same problem. I thought it might have been an app I installed - I uninstalled all apps that used the camera. Still no dice. Did a factory reset. Still no dice.
Called Verizon and explained that I'd already tried a factory reset to no avail. The service rep didn't ask me to do anything else. Because I've full device insurance coverage I'm getting a new phone overnighted and should have it no later than 3pm tomorrow.

I had the same issue and tried factory reset, 3rd party camera apps. nothing worked even updated camera firmware and phone firmware still black screen with camera fail. I took off the battery cover, removed the battery, removed the phillips screws in back. carefully popped off back housing and the camera flex cable is right there. i simply unclipped and reconnected it and made sure the camera was seated tight by pushing on it.(carefully as not to damage lcd). I will say i have no warranty because i bought second hand but the are no void stickers over screws so no way to tell its been opened. camera works perfect now. I repair phones as a hobby and remebered the galaxy one having a speaker issue just like it. anyway worth a shot or if you have a warranty just get a replacement but it took me about 3 minutes,
Camera fail
I would like to update the post with my findings:
Since my last post, I did a warranty exchange on the phone. Upon receiving the new one, I reverted the broken one back to stock through the tutorial on XDA (using a prev leak bootchain, ODIN flash, etc).
All went flawlessly, and after reverted to pure stock, the camera worked again. I re-rooted and re-flashed a variety of ROMs (ASOP & TW). camera worked fine through all of it. It wasn't until I did play store updates that things went bad. After the updates the camera stopped working again. So Once again I flashed back to stock. Camera worked again. I felt comfortable doing this as I could re-produce the problem and solution.
After fooling with app updates etc I determined that the Google Talk / Goog Hangouts update was the culprit. Once that was installled the camera was inaccessible. I have since not taken that update (been a few weeks now) and all is still fine.
moral of the story to folks out there, watch out for the Hangouts update. I dont have any more info than that. Just wanted to share.

I would just like to share my experience, it may help someone... I also had this problem and fixed similar to desc. above... I had taken apart phone and cleaned out mostly all of my connectors because of water damage/corrosion issues.. I suppose I had bent the cam ribbons slightly out of place... this in turn, for some reason maybe somebody with more knowledge can answer, caused the phone to no longer power up or show any sign of life... I could not figure out and ended up paying my deductable for new phone... I knew it was specifically related to me removing the cam because I had already cleaned and got phone to a working state, but the cam didnt work so I took apart again cleaned cam port and voilà my phone stopped powering up completely... wtf! sooooo I just recently went back after reading above, and dramatically bent the cam ribbons to make sure contact was good... now everything works.. ya live and learn

No no I sent the refurb one back to vzw. Had a lot of bad luck with factory refurbs.
i know this may be a necro thread, but I just had the same issue and I solved it by replacing the front facing camera/prox sensor assembly. tried new main cameras first but when those didn't fix it I replaced the front facing and everything worked fine.

Use the Touchwiz JELLYBEAN 4.1.2 VERSION
I'm brand new to this forum, but my uncle has been a member since 2008 and says you guys are the best when it comes to helping with problems for Android.
I'm having the camera issue, as well, and it spans across all camera apps, snapchat, Skype, etc. I just now discovered the front facing camera works when before it wouldn't even let me switch to it, making me think both cameras were dead. I've tried a different ROM, kernel, battery pulls, rebooting, everything in the list. I even dismantled my phone and pressed the connection in a bit, and still no luck. (Thankfully I didn't completely wreck my phone, though.) I'm trying switching from a different developer now, since I was using the only two TouchWiz ROMs I could find for my Cricket d2cri, both by the same guy. I'm hoping against hope it's an issue with the guy's programming and that it's not a sudden hardware failure after nearly a year of having the phone.
If anyone happens across this thread and has any ideas that haven't been said as to what I can do, please, throw me a message or respond to the thread. What good is a phone without a camera these days?

I am having the same issue, and I did try many things: revert to stock, changing kernel, try other camera apps, wiping camera app datas, Still nothing, if someone can help with other method please.
I got "camera fail" after i flashed ArchiDroid 1.7.2 coming from PAC nightly. Then flashed ArchiDroid 2.2.4 and camera got fixed. All flashes where clean
In my experience, custom ROMs and kernels can also cause this issue. I flashed a different custom ROM and voila, my camera was working again

hi I was having the same problem with my camera and I installed 3rd party camera software and the camera seem to work using this. I used camera mx
Camera faillled warning
I HAVE THE PROBLEM OF CAMERA FAIL WARNING IN S5 SENSATION ROM
I AM USING S3 Gt i9300 IS THERE ANY SOLUTION FOR THIS PROBLEM
THE CAMERA DOESNT WORK ONLY IN S5 SENSATION ROM
That is usually caused after flashing a custom kernel without having opened the camera app at least once with the stock kernel.
Go back to stock kernel, open the camera and it should work. Now flash the custom kernel and don't do a factory reset or you'll be in the same again
Which kernel you using? If you on 4.4.2 i recommended Archi Kernel.

[Q] Help with camera issue

I got this issue on my s2 that is set up with the latest cyanogen rom
Happened all of a sudden randomly when i tried to take a pic i noticed it like that. Front camera works fine.
I have tried:
Factory reset
Different roms / kernels
hitting it...ye i know it probably doesn't help but everyone tries this!
The reason why i'm posting here is because I was almost 100% certain that it's a hardware issue but there was a kernel I installed that actually let me use the camera for about 1 or 2 minutes before it broke down again and that gave me doubt about the hardware thing so i'm asking you guys maybe someone can help.

(Sorry, new user cant post outside links but i have to show you the picture to understand my problem)
Is it blank screen or is giving you an error message?
If you think it's hardware, flash a stock ROM and see if it's not working as well.
If it is, reflash CM.

[Q] [HELP] Jiayu G3N Touchscreen Issues

I've got a Jiayu G3N (s501 Chip) and there's this issue that started yesterday, where there's a half-inch horizontal area about 3/4 down my screen that doesn't respond to touch. It's kind of like this one, but mine's horizontal:
http://www.youtube.c...ed/zIuDN8A2rGs
I've had this issue before where the keyboard goes unresponsive, but a simple back-reload of the keyboard fixed it, (might be unrelated) but this same area has now been permanently unresponsive and not just the keyboard.
What happened was I've had a friend with a faulty SD Card, and he tried it on my phone to see if it works and it's not his phone's SD Slot at fault. The process took us a few Boot-Poweroff sequence, and in the last one it's where I noticed that area was not responding to touch any longer. (This could not have been the reason - or, it's the bootup - poweroff sequence was the one that did the damage, but not quite sure)
I was on Lolfisch v1.0 at the time. Tried rolling back to stock ICS using SP Flash Tool, formatted my own MicroSD Card, still nothing. It's at this point I'm considering doing an RMA with Merimobiles, so I've contacted them about it. The rep told me to email the Tech Support, and of course I did. They said they'd honor the one year warranty they have if it's indeed hardware issue, as they are still in process of looking for an update that can possibly fix that issue (I doubt there is any update, since my Stock ROM is the last and only Official ROM Jiayu released for the G3N) I got my phone last April - so two months into use and I got this damage.
Details of my Stock ROM:
Baseband: Maui.11AMD.W12.22.SP.V5.2012/07/2 20:13
Kernel : 3.0.13 [email protected] #1 SMP Preemt Sat Feb 23 07:13:56 CST 2013
Build : G3N 20130223-071508
Anyways, I still have the issues with stock ROM. Tried Lolfisch one again, and still the same thing. From ICS to JB back and forth, still no joy. Tried it with and without SD Card, still nothing. All the possibilities of anything software-related I've tried so it's definitely Hardware issue (probably Digitizer)
Anybody got the same issue? I will update the community on how this goes, as well as how Merimobiles deals with this kinds of issues and their RMA procedures.
TIA
UPDATE: Now there's another half-inch unresponsive area just a few lines above the original one. The phone just sat on my table, and when I unlocked it, I noticed a new unresponsive area. The phone's just degrading each day.
UPDATE 2: Now there are a lot more unresponsive areas and has even extended to my capacitive buttons..RMA is here, 2 months to get it back..

Hello,
I'm having the same problem. How did you solve yours? Changing the digitizer seems to be the only option.

The first time it happened, Jiayu replaced the entire handset..
2nd time, it's still here with me and still broken..
and yes, seems like replacing the digitizer is the only solution..
maybe Jiayu cheaped out in this material since the entire phone's materials are great, including the battery..

Tablet Z LTE : Camera not available / connected

Hi there !
Tablet was pure stock , not even rooted when suddenly I couldn't start camera. It would say something that would translate to english like that " Error: camera is not available " or " Error: camera is not connected" .
I already tried:
- Using OTA to update to 4.2.2
- Flashing 4.2.2 using flash tool
- Unlocking bootloader and flashing P.A.C ROM.
- Wiping cache/dalvik cache/ fixing permissions/ wiping everything
- Downgrading to 4.1.1 original Japanese FTF.
- Rooting it and installing DOOMkernel
Nothing helped, still same error, which plaguages nearly every xperia phone/tablet...
I seem to havethe same problem
I have the exact same problem as your tablet, and mine is the 16 gb wifi model (Unlocked, rooted), The camera stooped working a few days ago, while i was running CM11, i assumed it was Kit kat, but the camera was working fine up until it randomly stooped working, so i reverted back to stock 4.2.2 (Flashed the SGP311FR 10.3.1.C.0.136 via Flashtool) and the problem is still there.
Im praying that it isnt hardware damage, due to the roms ive been using, and hope that its definitely software related. Im going to try ubuntu touch now, to see if a completely different os will make it work.
Do not worry guys. I had the exact same problem a few months ago with my SGP321. I tried all the things that you have mentioned above and still did not manage to get the camera working. You will have to be a bit adventurous to solve this issue. It involves opening the back panel of the tablet. There is an official teardown video somewhere on the Sony website which will give you an idea how to open it.
There is a very thin cable that connects the camera on the mainboard. It has probably gone loose. I had dropped my Tab a few times so maybe it must have become loose. Upon opening the back panel I saw that the cable was a bit loose. So i just snapped it back in place and voila the camera turned on. The only headache is that the back panel does not 'feel' waterproof anymore because it was opened. But i managed to glue it back again and since 3-4 months there have been no issues. Hope this helps! :good:
It worked
Thanks aashayjardosh
its quite a easy fix, the camera cable was not clipped in, so it must of fell out due to force (dropped, or thrown). i can say, im quite happy, not only did i fix my tablets camera, but i got to see the insides for myself , for now, i wont be dipping this thing into water any time soon, not untill i get some propper water resistant glue, and properly seal it.
