Front Camera - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Yooo. Okay so my front camera just stopped working out if no where. Every time I try and switch to my front camera it will freeze and say camera failed or just stop and I'll have to kill the app. Same with instagram and snapchat. I was on stock when it happened and just now switched to the 4.3 ROM and its doing the same thing.

I'm not having any issues with CM9 so far. Running great. Might be a bad download.
I've tried to reflash three times even the newest release has the problem

Works fine for me.
I flashed it a few hours ago and had no problems with shooting photos or video on either camera.
I tested out the camera quick to see if it worked and I could change settings and also use both the front and rear cameras.
I figured it out, it was a Theme I was using from the play store that was causing the camera options to disappear
Thank you

Camera not working?

So I have had this phone for 5 days now. Everything has been fine but today the camera has randomly stopped working.
When I load the camera app it just shows a black screen with all the usual camera logos.
I have tried accessing the camera from facebook app and its the same. I have also tried from snapchat and in snapchat the front camera works but when I switch to back the app almost locks up.
I have tried restarting the phone several times. I have force closed the camera apk and wiped the cache.
Does this sound like a hardware fault?

Sounds like it, yes. If you are getting no picture from the camera with multiple apps, it must be a hardware fault. Instead of trying to fix the problem yourself, just return the phone under warranty and let Samsung fix it. I'll assume you're still stock? You didn't specify this.
Sent from my GT-I9505 using xda app-developers app
Yes it is still stock.
I phoned up phones4u coz thats where I got the phone from. I have insurance with them so if the phone is ever faulty I get a brand new sealed unit instead of it being repaired.
They advised me first to try a factory reset incase there is a corrupt driver. If not I take it back this afternoon and they will give me a brand new one

Black lines on the camera?

Just wondering if any one else has experienced this problem where occasionally black lines appear across the screen on the camera? Seems like a battery problem to me.. any ideas?
*You can see it the most just after I take a picture
Take a look https://www.youtube.com/watch?v=KglLOKnSSuE&feature=youtube_gdata_player

I couldnt see any black lines in the video
Watch it again maybe it was hard to see if you're viewing the video from a phone because of the orientation on YouTube

Compare these 2 screenshots taken with a half a second gap in between( look at the edges of the screen)
Only seems to do it on the Samsung camera app, I downloaded jb camera from playstore and no problems there but the camera sucks in comparison

That looks remarkably like Interlacing. Using a US model, by any chance?
It's probably just the software re-rendering the live view.

It's the European model I bought it within the UK no one else seems to be having the same problem, it totally ruins video capturing as it shows on the videos :/

And it doesn't happen on other camera apps? That's peculiar.
Have you tried emptying the data and cache of the camera app? Cleared the phone cache? Factory reset?

All of the above, plus do you have any pending software updates available to you? Does it do it everywhere you go? I thought I had a problem with my N2 camera once, but it was actually the florescent lighting in the room.

Omg i just cleared the data/cache in applications manager and then started the camera up again and it's perfect no sign of any more black lines /flickering!
Don't understand how but it worked thanks!
Sent from my SM-N9005 using XDA Premium HD app
I see the lines in the original video! Can I ask what did you use to take that video of the screen? I'm still waiting on the AT&T version, but as soon as it gets in, I'll be looking for that issue as well. The Camera app is probably the most important to me.

Then what I'd do is:
1. Factory reset
2. Reflash ROM
3. Exchange phone

Ya i guess will do that, but a little later. Phone works fine otherwise and honestly i don't even think i will use any of this features, maybe wait for a few months and then get a new one in exchange
It won't work in dark environment, you need to be in good light.
