You are saying Any custom rom i doubt if thats a true statement .
If its that important post in the right section and read the Q&A FAQ post Q12.
Judged by your multiple posts on the subject and your past posts re camera its possible you broke the hardware .
jje
OP doing something wrong... AOSP Camera works on CM10.1 now, and derivatives of course. And even before, simple workarounds like Huawei AOSP Camera worked just fine.
Suggest that OP flashes stock JB (any) and checks camera firmware and updates as necessary, then wipes absolutely everything in a later CWM and re-tries a "custom" ROM.
Re: [IMPORTANT] Camera doesn't work in any custom rom
Camera driver issue is probably the only thing I can think of that force crash the came right at start up, or display messages like "can't connect to camera"

if you are from ICS and then updated to JB maybe its the phone and camera firmware that causes the reboot.
however i haven't experienced before the sudden reboot when opening the camera, it just freezes from what i remember that happened to my phone.
maybe this thread is worth checking for: JB 4.1.2 and Camera Driver
if changing the camera firmware doesn't help, you can try to wipe cache/data, wipe system, wipe dalvik and wipe preload before flashing.
i haven't saw a post like this before so the above suggestions aren't sure to fix your problem but i think its worth trying.
At least you are not getting any errors in your logcat, so just install a stock JB and flash a proper camera firmware and try again.

I tried everything you said but it doesn't work. My Camera Driver is ZH* (I know, it's strange but I can't use any other because if i use other driver doesn't work on stock rom) I can't find other ZH driver...
With the last nighly of CM10.1 camera works. MOD close the thread

I am having this problem for a while now...my camera doesn't work.when i press the icon, camera application launches with the camera buttons and then with the small preview icon on the right side being black.The screen displays what is in front of the camera but the buttons are totally not functioning. If I wait for it, it then says "camera application not responding" then gives me the option to wait or force close.
-rebooting doesn't help
-clearing data doesn't help
-using another camera application (same result)
-The best solution that I came up with is reflashing ROM (wiping everything)
-if that doesnt work, reformatting SD card
sometimes it works..sometimes not
when fixed, it just runs for a couple of weeks then afterwards, the same thing happens again and I am getting tired of it.
So I would like to seek out your help now enlightened members of xda...please help me
PS..this happens on any kind of rom (oxygen and currently LEWA OS)
Anyone out there who can help me? anyone who experiences the same issues?
Do u have any kind of cell tracking application(like androidlost or something) installed on ur phone? Or any other app that uses camera?

The camera work on the official firmware? (V20E) When did you first notice this problem?
Typically, problems arise with the camera when changing kernel ... Try to flash the kernel from Franko

After Flashing Oxygen V2.6, this problem started after several days...was able to resolve thru reflashing rom wiping everything but after several days reoccured.
I am already using LEWAOS M7 and it happened to me twice now.

why dont you get back to stock firmware and see may solve your problem if it is really rom related problem
do a clean install by kdz or lgmdp
Press THANKS button if this guide helps you.
Since we know that CM9 RC2 is too buggy, we are forced to use RC1 instead, until its fixed by Wayland.
This is just for you guys stop once for all asking about etas and other stuff anoying.
Please, after read this, dont make any question about camera, kernel updates or deep sleep.
Follow this and get the RC1 ROM from Maclaw working with 100% camera from RC2, but without its bugs like GPS and Bluetooth not working, SDEXT not recognized etc...
BEFORE you start flashing this, make sure you have enough space on system/app, because libs and camera app from RC2 are bigger than RC1's. Delete some ringtones you dont use or some apps. The same for kernel, the dev says about 4~5 MB free space, i recommend about 7MB, for kernel and camera app. (delete the CMWallpapers apk, it has 7,04MB, and im sure you dont use it)
1st, download Maclaw's CM9 RC1 ROM
DOWNLOAD
If you already have it, skip this step, if you dont, make a full wipe then flash it. Reboot your phone.
2nd, download Nims Kernel 2.1 with Camera app and libs fully fixed from RC2
DOWNLOAD
You don't need to mount this, just flash it. After flash, reboot your phone. If everything was right, the screen "Updating/Starting Apps" should appear. When the system starts, test the Camera app, it should start normally, if you get some FC screen, or "Cannot conect the camera" message, try to re-open the app. This message will appear sometimes, even in 3rd party apps, like Instagram, but is just you re-open it.
3rd, download the lastest Nims Kernel available
DOWNLOAD version 2.2.1 for ICS ROM
This ZIPs files are from this thread, i just put them together for make it easier for you guys.
I'm not responsable if it bricks your phone.
For me and a lot of people it works.
this was what I needed, now I'll change to ics again and finally I definitely thank you very much

If you follow this guide exactly as you put it, you will end in a bootloop just like me.Explain better
Very good work
Well just tried all the steps above but sadly it isn't working .
After I flashed nim's 2.1 kernel the phone boot into system upgrading screen and stuck there , I did a restart and the phone got stuck on a boot loop.
Flashing nim's 2.2 kernel after that didn't helped either ..
Please explain the procedure in more details.
Thanks Devs!

You might do something wrong...
you dont need to mount system for flashing this zips....
Try to make a full wipe and flash RC1 again, reboot as normal. After that flash cam app and libs with nims kernel 2.1. Reboot again.
Then flash Nims kernel 2.2
Just for guarantee, after you wipe install RC1, delete somethings you dont use in system/app, because cam app is biggest than RC1's.
Some screens of this working properly
Nice tips, thanks. Can I ask you a question??? Does this ROM drains battery much??? The last time I use it, it drains like hell. I need to know if it still drains battery so I can apply your tips

Well got this thing working , Thanks @jmendes.
Edit : After using this ROM for a while I found out that deep sleep isn't working .. ( google location was off )
For me deep sleep works until i take some 5 pics... after that the camera stops and i need to re-open it. Then deep sleep sucks as well :c

ROM stays unchanged. If you had use RC1 when it was out, it keeps the same way. Obviously, battery will drain faster than CM7, but it just need some adjustments by the devs, hope itll fixed in Wayland's release
It might even "work" (not sure if the need for closing and re-opening the camera app several times means fully working...) but I doubt the quality of the pictures will be as good as in a GB based ROM.
For me or anyone who uses the camera sometimes and don't want crappy quality pictures, any ICS or JB ROM shouldn't be considered for now. In fact, without OpenMax drivers I guess we'll never see camera working properly on Galaxy Ace running ICS and JB

Jesus Christ! Fully working for our situation means a app who opens and take a photo with auto focus, flash working properly, with all configurations available with a gallery without bugs AND apps 3rd party accessing camera drivers! It's known that it has a lot of bugs, but its better than an app that just take pictures and break deep sleep resource. Everybody knows that OpenMax drivers wont be release for us, and a camcoder wont be available either, bbut they are really working hard to give us a decent camera. The quality is the same on GB. As you said, "shouldnt be considered for now" so dont use it. If you think it's not worth it, stay with your 2.3 version.

Hmm, you said that flash is working properly ... is the LED working for flashlight apps as well in this ROM ? Last time I tested CM9, it wasn't working and flashlight is very very useful, can't live without it. If yes, I'll try it.
By "camera working properly" I meant taking photos with good quality, and auto-focus and flash both working. That is enough. I did'nt say "fully working".

Go until Wayland's CM9 topic and you will see that for this he will need to put a modified app for flashlight working. But still works.
And yes, the quality keeps as in GB. With auto focus, flash and cam modes working rightly
Hi,
So I am a huge fan of Android and the development community here
I don't like Apple at all, however I keep having to switch back- because their product is far more stable
Now- I'm using rXtreme v12, and nobody else using the ROM is encountering the of crashes I am having. I've uninstalled some mod's (like CRT-off) and several app's I felt may have caused it. I'm not using any theme's, and I'm not running NovoLauncher.
Crash= phone reboots instantly (no warning) then freezes at startup. Battery remove required.
The only evidence I can link to the crashes (phone worked perfectly until this began happening):
The stock browser began to 'forget' me- Google asking me to sign in at the home page even if I haven't exited the browser, and my never rebooting to my browsing sessions.
Otherwise the crashes are completely random- pressing the back button whilst listening to music, responding to a message, closing an application etc. They occur 1-3 times a day.
I had an 8GB MicroSD card, and I've just replaced it with a brand new 64GB one- so I don't think this is the problem.
I've read through the freezing thread, and I am based on the "most stable/crash free build (XXBMF1).
I've been using it (well, without a SIM card because I can't afford to be using an unstable phone as it's for business) for about 3 months, and I've been through multiple versions of the rom, and done countless wipe's, and re-installs.
Is there some error logging app I can installed to try and narrow down this issue? What else can I try?
define "crash". provide a logcat. Google it for a guide
Do you mean that the entire phone crashes and reboots, or just a particular message pops up

Im not ready to give up on this rom yet- a vert last resort
I use this ROM for these features:
- Supports LogMeIn
- Supports MultiWindow
- Long hold button light/music changer volume buttons
- Battery saving features
- S tweaks (volume boost)
- Titanium backup
- Mega Bass beats
So the browser issue I mentioned (how it doesnt store my sessions, or remember im logged in with google)- does that not link to some other problem?

there are other Roms that support some of those and if you mod then there are mods for 5 of all what you said though i don't know what Logmeln is as for the browser you could simple use another one

I've got a copy of LogCat and I'm recording. I guess all I can do is wait for the error? I'm trying to force it somehow.
Try another rom all this stuff you want you can get easy using/flashing some mods or download from playstore. Do some research on what you like really in a rom not just a part of it and flash it.
In your world I would be considered crazy, in my world too but they know me here at least.
So nobody can make any link my browser issues with my crashes? Please try. Before I switch roms can we figure out this problem first?
I've just wiped and installed a full new rom (rextreme 12 using jkay) and the stock browser still keeps asking me to sign in, and doesnt remember sessions! Very frustrating... surely if nobody else has this problem- it means something is wrong. Please help

It looks like I've resolved it myself.
I installed rXtreme 12, but this time I used jkay (not samsung stock). What is this- the kernel?
So far it's been a bout 4 days of heavy use, and no crashes. My browser still doesn't remember my sessions, but I'll just have to find an alternative.
Does jkay still have the battery optimization built into this rom?
Help please!
I flahed the last rom of sniper killer and when the phone ask for the pin...the keys doesn´t appear,you see nothing in box of PIN, but though you press the correct key when you finally press accept...the phone says "pin incorrect..retry.. (or so)..". I have wasted the three tries...and after started to ask me for the PUK
with the same procedure (pressing corect puk but no appearing what keys are you pressing)....I have wated two..and only left 7 tries.
I have stopped..because I don´t know what to do! If I follow I will waste all oportunities of inserting the PUK!
