Buggy FF camera - JVH Rooted + CWM + Voodoo - Galaxy S I9000 Q&A, Help & Troubleshooting

Dear All,
I am having an issues with the front facing camera on my SGS. Seems to be some problem in the kernel. My current kernel is 2.6.35.7#Voodoo and front facing camera is disorted and cutted into 4 or 5 smaller parts.
Please advice, thanks a lot.

Have you tried a different kernel to support your theory ?
I seen this reported in all kernel threads. So its either not a custom kernel issue (even in CF I seen this reported) or its a rom(maybe app?) issue

Strange
I do not have this issue with the stock JVH kernel (unrooted phone). So I assume this must be caused by custom kernel...

Camera not working

Hi, i've got a litte problem.
After flashing my Milestone my camera is not working. I've got a screen but when i am pressing button then my phone got a black screen and I have to remove battery. I don't have this problem with FroYo G.O.T., only with Mods and roms from Brazil. Can anyone help me with my problem?
sorry for my english

Same problem, with camera screen bluring... I've read that it's regard to the kernel, but I've made a rollback to 2.1, and still with problems, any idea?
Ovitz, it would probably be of massive help if you said what ROM you've flashed...
I have Iceandfire CM7, i can't make a movie but i cant make a photo. My camera is fully working with Froyo G.O.T. and stock 2.1
If you go to the CM7 site it says in the list of bugs using the side button for the camera "unleashes hell" I suggest you have a read through the rest of the bug list

My camera can take picture on these ROM but can not play video . Can anyone play video on Ginger cook ROMs?

CWM zip fix for Front Facing Camera?

Hi
Apart from going back to JS8, is there anyone has a fix for the front facing camera orientation or is there a custom rom that fixes it? I'm getting desperate...
Using Fring video test call, the received video is upside down. Tango and Qik are effected too. I'm getting corrupt video recordings from the FFC using Qik.

damain posted a fix and several rom makers ported it over to their roms as fixes and updates
I've been looking for an update or kernel but am a bit of a newbie as regards custom roms etc. Is it possible just to apply a camera fix on the stock JVH ? I do have cf-root.
Have not found a fix for this yet. Is it a gingerbread bug or is it just galaxy s owners are having this issue?

+1, I was using Damians's JVH kernel and his CWM fix worked great. Not sure if it will work with CFroot, most likely not.

p990 cm 7 camera lag.

Hy , I have tried cm 7.1 and cm 7.2 on p990 and on both the cm camera lags in low light conditions , I even tried instaling lejay's costom camera and i get the same result 5-12fps in low light condition(if i use the stock camera ported to cm7 it works great but has lower bit rate) can somebody help my with this? I have research the forum and found out that many use cm 7 camera without any problems.

Try ICS camera from play market, works for me.. Or it might be kernel's fault..
Try to flash another kernel, i think that its the problem
I will try another kernel but i do not think it will make much difference since the camera driver is most likely in the rom not the kernel and even if the faulty driver was in the kernel i doubt that the costom kernles have a diferent camera driver than the stock cyanogen mod.
Why do you want more BPS? 17 is already good... more cause me lag when I record...
Sent 2X faster with my LG
I tryied another kernel and as i expected nothing has change ( the camera driver is in the rom not in the kernel ) i still get lagg in low light with cm7 camera. The main reason i want cm7 is that there is a pach that enables focus in video recording while in stock camera there isn't any.
Can someone that is using cyonogen mod 7 camera confirm to me that he has no lag in video camera recordings ?I mean someone who knows what he is talking about.
I found the issue is that lg did not use the standard android camera libraries, they made other libs for the stock lg camera,The lag issue is because cynogen mod and other market camera aps use the stock rom android libraries located in /system/lib directory libcamera.so and libamce.so that are the stock android rom camera libs , apparently lg camera hardware is not compatible 100% with this android stock libs .If there are people with p990 that have no lag with cynogen mod 7 camera in low light and other camera market apps I would be grateful if he would post the above mentioned libs libcamera.so and libamce.so for my and other to try on our devices.I wonder if i use a g2x rom would it function on my phone or just use there camera libs ?

have you tried the mod made by Kostya?
cam stock mod
http://forum.xda-developers.com/showpost.php?p=21956617&postcount=1639
Is you ask us if we have problems with low fps during a lowlight scene with CM7 - Then yes, yes i do
But the stock camera has been portet to CM7.
The stock lg camera has no support for autofocus.And i found out the real problem for lag is the automatic exposure compensation i am using lgcamera from market and it has exposure compensation options .When i set the exposure compensation to" -" the lag is gone .

Screen displaying wrong things

Hello, I got a serious problem with my Galaxy S..
something must be wrong here, when I'm on ICS, photos are displayed like they had a very poor quality or something like that..
I'm running SlimICS and tried devil kernel with and without Voodoo color, this didn't change anything.. even when I changed the VC values..
When I start my phone, at the point of boot up when the devil kernel boot screen appears, it first appears usual and within a second changes to some strange view, like you can see on the photos...
http://db.tt/qIhJejyu
these are pictures of the devil kernel boot screen, the other photos are pictures viewed on the phone. I hope you can help me
when using other kernels/roms(ics) the same thing appears so it's not kernel related
am I maybe posting in the wrong section?
can nobody help me?
Looks like a VC issue, have you tried some stock/custom GB roms?

GB is fine, but I want to have ICS goodness
ICS rom without VC has the same problem... I also tried Devil without VC...
But on GB rom it is OK? ... maybe you should try clean install of Slim ICS, that means - flash stock 2.3.6 jw5 (link to gb flash kit is in ics333 thread in development section), root it, flash newest cm9 nightly, and then slim ics and kernel, first try semaphore, then devil3 ...
yes, it's perfectly fine in GB..
already did this 100 times
Maybe you are doing something wrong if not, it may be a hw problem, but I don't think so...
don't know whats wrong with the device, ...#
EDIT: Okay, I guess I got it, as this device is pretty new, I got it replaced due to a warranty case, I think it has a newer display or something, which isn't supported by the drivers used in all AOSP based roms (CM7 also doesn't work)... pretty bad
Interesting... don't you have a Galaxy SL? It is SGS but with normal TFT screen, not with SuperAMOLED...
No, I don't have this ****..
Real SAMOLED I9000

I'm facing the same problem. With GB kernel it looks fine, but with any ICS or JB kernel colors go really wrong
It's the first time I see it.
Any idea?
Seems to be a driver issue
I am having this issue too.
There is a video in youtube titled "CM9 on Samsung i9000 framebuffer bug ('blue color bug')" showing the same issue.
In the comments they say it's a problem with framebuffer (fb) driver.
I have been taking a look to Samsung's kernel fb for tl2796 lcd panel (which I suspect it's ours) and there is a feature called ACL which is missing in CyanogenMod's fb driver. This feature seems to perform some colour corrections.
I am willing to solve this issue but I have no knowledge about kernel drivers nor graphics drivers. I have been reading about it in different manuals and articles but I'm still lost.
I would thank any developer to point me to the right documents to learn how to solve this issue.
Maybe pawtip or stratosk could help.

[Q] camera failed, downgrade to 2.2

Hi good afternoon,
I have red some forums for my SGT p1000, but never found answer to my question.
I have tried several ROM (4.04, 4.1.1) but still can't find the one with good camera. While opening the camera, it always crashed "Camera not responding". Also, tried some application from Google Play as advised in other forums but they still failed. stucked at camera initialising"
I also restocked using Overcome safe method.. tried the camera, and it also indcates "Camera failed".. I am not sure what have happened since I came from 2.2 ROM wiith the camera working flawlessly.
Can someone give me an instruction on how to downgrade to 2.2 and link to official 2.2 ROMs..
Thanks and really appreciate if someone could help
why don't you just use the overcome gb stock safe method that you used before.
it will be an official GB JQ1 rom.
why must it be a 2.2 ?
Edit: didn't read that you said overcome stock safe also has camera failed.
strange.

no, it's not just sound but the camera won't open.. that's why I want to try 2.2 to check if my camera app would be fine.
BTW, what JellyBean ROM are you using?
I'm using SCH-I800 (gtab verizon) and I'm stuck with camera not working. Error : camera has stopped.
I'm tried 2 rom : cm 9.1 p1c and aokp milestone 6.
Anyone got issue same me?
MDP issues
Could MDP issues crash camera hardware??
Could changing ROM from an MDP to a non-MDP crash the camera drivers??
hope anyone could clear things.. thanks in advance

I've had the same type of problem on my vzw tab. I played around with CM9 and the app would crash if using the flash. Right now I'm on an unofficial "beta kang" gb 2.3.5 ROM and the camera almost completely works, except it crashes if I try to use the front camera in video mode. (The front camera works for snapshots, and it works in other apps like Skype). The stock roms seem to be the only ones that have a 100 percent correct working camera. There are rooted stock roms out there, so I'd suggest one of those.
