CM 10.1 Camera Trouble And Possible Workaround - LG Optimus 4X HD

Can't post yet on android development forum so I'm posting this here.
I noticed some people who have recently flashed cm 10.1 have issue with the camera getting stucked for ~10 seconds before flashing and taking pictures when flash is enabled. Some people don't suffer from this issue however.
This is my observation while using the camera as I have also recently flashed cm: When flash is enabled, using the autofocus feature(touching the screen to focus before hitting the capture button) triggers the ~10second hang. Hitting the capture button immediately however without using autofocus doesn't suffer from the same issue.
Hope this helps someone

[Q] camera no longer working

Hi everybody,
I updated cym to 7.1 a few days ago and since then the camera no longer works. When I click the camera button the first image the camera sees freezes and that's it. I can't focus on anything else and nothing happens until I push the exposure button again and then all I get is a fuzzy, blurry picture of whatever the camera first saw.
Anyone have a solution for this problem or know what's causing it?
Thanks for your help

[Q] Camera screen black, but able to take photos

Hey guys, hope you can help me.
I've been using Cyanogen for a few months and now I face this problem:
When I use the camera, i see a black screen with controls, and can take pictures, however, I see a black screen and not what you expect to see as the view is the camera lens.
I've tried doing a nandroid (just in case camera or something was damaged) a full wipe, applying a rom from scratch and camera works correctly...
I'm guessing it may be an app or some setting bothering.
I don't want to configure everything from start, please help me
More information: this issue seems to happen before installing Motomizer and applying one touch optimization, and if it's uninstalled, problem keeps going
I've found that at the same time I cannot see any video on youtube videos.... maybe it's an overlay video problem?
Anyone?
Solved!
Dear jhonnyx,
I had the exactly same issue and I found it was a Kernel issue.
I was using wrong CF-Root and solved it just by flashing new kernel.
To solve the the problem just flash another kernel for your device, I prefer Siyah or DorimanX.
Hope this will help!

[Q] Camera Unable to Focus

Hi,
I have a H1 and today morning i thought of taking some pictures in my garden. Everything went on fine and then all of a sudden my phone's camera was unable to focus on anything. it just stays blurry. and when in touch to focus it just keeps changing the metering. if i turn the app off for 5 min and turn the camera on again it focuses for a few seconds and then again loses focus.
Could this be a hardware issue or software issue? im running ARHD 7.3 with a stock kernel.
regards

I had tried that among other things like changing kernel and upgrading from arhd 7.2 to 7.3..
.
But I noticed something, my battery was low so I was running at 1ghz and now it's at 50% and the problem has gone... Could be a mix of diff software issues.. Fixed for now though... Whew!!!

I am having exactly this issue..
After a few seconds camera can no longer focus -
Stock T-Mobile UK
Could be due to low power or might also be because of dirt/dust/spec in your camera lens

i fixed the issue buy just putting my phone on charge! it was definitely cause of the low battery. ive programmed setcpu to underclock it to 1ghz when it reached under 25% battery, so that was causing the issue..since then ive not seen the issue crop up again. i highly doubt dust can get in so there shouldnt be any need to panic about it.:good:

hmmmmm....wow i thought it was a custom rom issue..maybe rooting the phone and the installing a cpu governer like daemon or setcpu might help..you try setting minimum frequency to 1.2 and see if that helps..
coz i got myself an O2 version from uk and installed a custom rom on it.. and well one morning it started acting whacky..but putting it on charge helped..it could be possible..i sifted through the other posts and i believe we are the only 2 people who have faced this problem..but had it been a hardware issue it would not have been fixed so easily so im pretty sure its a software bug..
Could be a problem with the camera sensor over heating
Wow is that even possible? I did not know that.. The problem Did come up after I tried some panoramic shots and a few regular pics out in the sun..

T-mobile have offered to replace my phone
And HTC UK have offered to take it for repair..
Not sure which option gives me the quickest turn around.
It's annoying as it works fine from time to time.
That's sad.. Coz I know how it feels to not have your phone with you.. I was lucky then I guess that it got fixed for me automatically.. But dad's theory could be correct about the sensor heating up.. Keeping in mind that it's more sensitive to light in the first place
Sent from my HTC One using xda app-developers app
and the problem is back again i was out with my friends last night and we were testing low light capabilities and the moment i switched to hdr video the camera gave up again... now its not even able to focus after being put on charge.. i tappe the phone a couple of times and it focussed but again failed..you think its a hardware issue
? or a power management issue by the kernel??(tried stock and bulletproof kernels)
Definitely sounds like the sensor overheating. On a lot of dSLR cameras with video and live view, they switch off after a short time to avoid the sensor failing

But I left the phone along overnight and it still had trouble holding focus for too long.. 5 or 6 seconds max... Could there be a possible software issue too coz apart from me only one other person is facing the same issue..

That is why it sounds like hardware fault. If it was software, then more people wold be getting the problem.
Once it has cooled down for about 5-10 mins then it will work again, briefly.
Send back for a replacement, is my recommendation
i cant...i had it imported so its almost impossible to get it replaced..ill have to figure something else out...
Anyone else facing the same issue? it keeps cropping up again and again..

"Camera Failed" after upgrading to KitKat...??

Got a strange issue here. My camera was working fine on JB (stock rom & also on KnoxRaid 2.6). After the kitkat v2 release of Knoxraid I decided to give it a try. Everything is perfect except whenever I open the camera I get "Warning - Camera Failed". I restored back to mj5 thinking it was maybe a hardware thing but no, the camera works perfectly on stock mj5. So I decided to test Knoxraid 2.6 (non kitkat version) and again, camera work fine. I have asked Drakeymcmb what he thinks about the issue, but I think it has even him stumped. He suggested I try the other kitkat rom leaked by designgears. So again I restored back to mj5 and then tried the designgears leak. No luck, camera failed. I have wiped my internal memory and tried everything I can think of. I am hoping maybe someone has run into this issue and knows a fix?? Please help!! Thanks!
Not having any camera failing, but I'm experiencing a pretty substantial lag after taking a photo.
When i hit the shutter button, my screen will say "Processing". If the camera moves AT ALL before the "processing" is done, the picture will be blurry -it almost looks like I've moved the camera during exposure.
Anyone else having this problem?

I notice that as well. I just turn the smart stabilization off and problem solved. Turn it back on when you wanna take pic in the dim light situation and be prepare to hold the phone still.

Were really talking about 2 completely different issues here. I wish my problem was that the camera was too slow, but mine will not load at all...

[Q] Possibly faulty camera. module.

Hello everybody.
I have been having a strange issure with my i9295's camera, and thought I'd get some feedback. For a long time I used the 4.2.2 rooted firmware and everything was fine, but then I broke the screen and replaced it, and decided to try using custom ROMs.
Now, I'm not sure if it is related to me taking the thing apart and putting it back together, or just from using custom ROMs, but the issue seems too convenient to happen on three different versions, with three different stock camera apps.
My problem is now, that whichever stock camera app I try to use, the phone will freeze for 4-5 seconds when taking a photo, and will completely freeze and make the camera inaccessible to any app until I restart if I try to shoot using HDR. I tried some random 4.42 version, Paranoid 4.4.4 and now CM12 5.0. They all had a different type or version of the camera, but all the same issue. Yet I have no issues using CameraZoom FX. I'd just like to be able to use the stock app for it's features and speed.
Is a non-working stock camera a known issue, is it a convenient software bug that happened to be in the exact 3 roms I used, or is there a possibility that I damaged the camera module when I disassembled?
Thanks in advance .
