[Q] [q] Back camera not working - black screen - Galaxy S II Q&A, Help & Troubleshooting

Hi, I just found out that my back camera is not working.
I've already tried this:
- hard reset
- format usb
- replaced camera.apk
- removed sd card
- reflashed the same rom (2.3.4)
- flashed ics (4.0.3)
This didn't help. Camera just doesn't work, stock camera app and any other camera app. Also the led light doesn't work. Movie with exactly same problem: http://www.youtube.com/watch?v=EKSdZbPQYqY&feature=g-hist&context=G2e8e3d1AHT3h97QABAA
Is it hardware problem (two days ago phone got wet, but not much ) or is there anything else I can try?

Sounds like the actual camera is broken.

Thanks for the reply. It is hardware issue - connection problem, will try to fix it tomorrow

Actually it might not be.
Since my last post i had the exact same problem after deleting something in titanium backup
I dont know the exact thing i deleted as i used batch delete
I restored my backup from CWM and it worked fine

In my case it was the connection problem. I just disconnected and connected back the camera and it's working fine now. I discovered this by pressing hard the back of the phone (sim card area) and camera was working while I was pressing.

[Q] Vibrate function doesn't work anymore, hardware issue

My SGS2 stopped vibrating. Tried flashing, un-rooting, restoring stock and factory settings. None of these worked.
I am inclined to think that it is a hardware problem.
Has anyone else been dealing with issue? I read some posts on XDA regarding this matter but they were software related as opposed to hardware. Can anyone post instructions on how to fix it or provide any solutions for this issue?
If its hardware, why not flash stock, remove binary flash count with USB jig, and return for warranty?

Cannot get jig in Palestine. Bought the phone from the UK. Sending it back will be problematic. I will look for a repair shop.
Thanks for the quick reply
That's a "bummer" (bad luck). You could make a jig, but as you said that it would be problematic to return. Hope you can sort it easily. Sorry, can't think of anything of use right now.

hey there,
i got the same problem. no more vibrating at all. not with calls or notifications and not as haptic feedback. it started today (was still working in the morning), though i did not drop the phone or anything.
i am still hoping too find that it's a sw-problem. but all potential solutions i find do not help. so i guess i have to contact samsung.
but before i do that i have to get rid of all "hacking".
could you plz tell me what i have to do?
i have now cm9 20120402 nightly.
but i still have a cwm-recovery-backup of the original touchwiz (gingerbread).
-so first i make a backup of my current rom via cwm and of all my apps via titanium and store everything on my pc.
-i flash my touchwiz-backup
-i get one of those: http://www.amazon.de/s/ref=nb_sb_no...ld-keywords=Samsung+Galaxy+S2+USB+Jig&x=0&y=0 , plug it in, wait til its done and remove it again.
after that, samsung will never know i "messed" with the phone??
or do i have to consider/do something else?
tyvm!!

I have the same issue.
When I was on my stock 2.3.5, I found a workaround:
- go into test mode (dial *#0*#)
- find the vibrate button, when you press it, it shouldn't work like you expect
- go back
- plug in your headphones and push the cable a bit to the left
- test vibrate again - this time it should work
- pull the cable out while vibrating, still pushed to the left, vibrations should stay on
I know it sounds crazy but it seems the hardware part that controls the vibrations is near to the jack port - excessive use of headphones, like it was case, must have damaged it somehow.
However, now I'm on CM9, so no test mode for me, I'm achieving the same effect by bashing the back button, so I get semi-constant vibration. I know, It's ridiculous.
Have the same problem here, I think it's software related because the shut down vibration stopped working when I flashed CM9 ICS, I can't remember if it was working anywhere else though. But now I'm back to 2.3.5 and it's not working at all. Did a Factory Reset, Cleaned Cache before and after the flash. Also used the Jig to reset my counter. Any clues?
I am experiencing the same issue.
Yesterday, I downgraded from 4.0.3 back to 2.3.5 as I was having a lot of problems with ICS. Now, my phone works fine again except for the fact that it does not vibrate anymore. (Which it did fine in 4.0.3 and before in 2.3.5)
I tried the trick Lechium06 mentioned in this thread but that did not work for me.
Anyone else having this issue? More important, anyone have a solution???

I saw something similar on CM9 thread, they said it could be a "bad flash", not a corrupted rom but the lack of proper cleanup before and after the flash. But I cleaned up everything before and after and I don't like reconfiguring the whole phone again for nothing.
it happend again.
dont recall what i did or if i did something last time at all. but it worked for over a year now. and now, my sgs2 doesnt vibrate at all, i tried all possible settings, tested with z-device and rebooted. nothing.
apprechiate any hint!
thx!!

AW: [Q] Vibrate function doesn't work anymore, hardware issue
since i had that before, i ruled out a hardware issue. it happend when i played with the system settings. but as i sayed, i tried to reverse everything i did. now after i updated to 0206 and wiped cache and dalvik, still no vibration.
is there anything i could have missed?
is there a possibility to reset all settings to default without deleting all my data?
thx,

I assume since your posting in xda developers that you are rooted?
If so, just back up data with titanium backup app and factory reset, setup system and then restore USER apps and data only.

Did you install another rom?
My vibration for example didn't work with some cm10.1 nightlies
it started in cm10.1 20130203. then i tried wipe cache and dalvik. nothing. then i updated to 0206 (wiped cache and dalvik again) > still nothing. went to bed. got up. everything ok! its vibration again! i am 100% sure, it did not work, when i left it on my desk last night. this morning, i checked for missed calls and it took a moment until i realized: i got haptik feedback back on patternunlock and keystrokes! checked ringtone-vibration: fine as well!
dont ask me how! would still like to know for myself.
thx,
kws
AW: [Q] Vibrate function doesn't work anymore, hardware issue
call me stupid!
suddenly this evening my phone stopped vibrating again. then i realized: quiet hours! i turned off haptik feedback at night.
could slap myself. at least ill find this thread again, next time i screw it again....

[Q] [Problem] Camera doesn't work.

My camera all of the sudden stopped working the other day. Whenever I try to use it, the screen goes black then force closes after a few minutes. I tried to download a few other camera apps and nothing happened. Currently running with no root and I don't want to root it until the camera is fixed, unless that would help fix it.

If you're on a 100% stock ROM with no changes and no root access with a camera that stopped working, there are very few things which can be done.
The only real solution would be to clear out the specific stock camera application's data directory. Not sure if this is possible w/o having to clear all the data.
I'd suggest the following steps in this order:
1) Manage applications under settings is where to look to clear out the specific Camera application data in hopes that only something was corrupted. Reboot and test.
2) Wipe all data on the device. Reboot and test.
3) If none of these worked, personally, I would return/exchange the stock device for another one as at this point, it would definitely seem to be hardware related.
An alternative route would be to gain root access and look into switch kernels/ROMs, but this could end up being a dead end if the issue is hardware related.
The only good/not so bad news is I've never seen the camera completely stop working on any of these devices .. at least not yet. So hopefully this issue is not hardware related! Good luck!
I cleared out the camera information and it worked the second I restarted my phone. Thank you!
That happened to me to, nothing I tried worked. Was good that I had ESRP. The Sprint store replacement the phone in lieu of just fixing the camera

Sometimes it's nice for them to just fix your phone and not give you a refurb. My sprint store seems to screw ur phone up when they fix it lol.
In the past when I was on the evo they swapped my screen out and broke my volume buttons. Then they just gave me a refurb.
Same thing happened to me. Suddenly, it doesn't work. Oddly enough, the Front Face camera does work by using the Mirror app. But the Rear camera does not respond when launching the Camera app.
I already tried switching ROMs, switching kernels, factory defaults, and nothing worked. Might be a hardware issue. I just hope it can be fixed without replacing my phone. It would suck having a replacement phone with HBOOT v1.50...

galaxy s3 camera problem

since new camera never worked i upgraded stock firmware made a factory reset but the problem is still there, the camera keeps a black screen freezes, buttons dont work and sometimes it says "camera fail"
would it be a hardware issue?
The camera should work with stock (out-of-the-box) firmware. You did the right thing and flashed newer firmware and also factory reset.
That should have fixed it if it was firmware issue...........
Rooting and installing any custom firmware would be a waste of time.
It's obviously a hardware issue, so re-flash the original firmware and return it for replacement asap.

Hi, I have bit different symptoms.
My back camera is working fine but I have problems with my front camera.
When I use my front camera it shows very darker screen than other GS3.
Also, when I want to switch from front to back camera it lags and switches after 5 seconds.
Sometimes it gives me error message when switching and it kicks me out to the home screen.
I don't know what is wrong.
I did the factory reset and the symptoms were still there.
When I reflashe the phone the symptoms are gone but it appears later.
I thought it was caused by one of the apps so deleted all the apps I have one by one.
Did not work out.
Will this be a hardware problem?

[Q] Camera app wont launch

2 days ago my Camera app stopped working either through the hardware button or software all it does is play the opening app animation and return back to the previous screen. Ive tried soft and hard resets of the phone and now ive even reflashed it via NCS to no avail. Now at this point youd think it would be a hardware thing, but apps like "panorama" and "smart shoot" still work and so do all the other camera apps ive downloaded. Anyone managed to fix this?
You seem to be the only one whom has had this issue and reported it. So no, no fix as of now since you are alone on this one.
same here

same thing happened to my phone since yesterday and I've tried hard reset but nothing changes.. Camera only works through smartshoot and if I try to open it just using the original app, or use the camera button, it just won't open and turn back to the home screen

I have exactly the same problem. After 5 days of perfect use of everything, the phone overheated, drained completely within a couple of hours and now it has a permanent problem with the camera: either black screen when launching the camera app, or if it launches, pink stripes and frozen app after 10-15 seconds. It cannot be just a random problem on one device. I've seen the same description of the problem on various forums.
Has Nokia responded on this?
The funny thing is that I live in Greece, the device was bought during a trip abroad and it's not covered by warranty! Regarding Nokia's amazing support policy I have written details at my blog nextbeta.com.
(I'm not a smartphone user that cannot understand what is a bug and what is a hardware problem, 8 years MVP for Mobile Devices and founder of the Greek Mobillity Club in 2001...)
Have you flashed the newest ROM or an older version? Perhaps you might want to try it with the Release ROM to see if that fixes things. Aside from that I fear your only option is to turn it in at a service center and let them figure out what is wrong.
Given that the Flash rewrites the whole system it somehow has to be connected with the hardware.

[Q] First I lost the camera, now the external speaker...

[Updated]
I recently put CM 11 on my Verizon S4. Everything was working fine. I decided to update to a more recent nightly (likely last weekend). After the update, my camera doesn't work any more. When I go in to the camera it shows a blank screen for the camera image, freezes for a while and then a popup says that the Camera Failed! After googling, I tried restoring the previous CM 11 image that worked previously. I tried wiping the cache, force closing the app and clearing cache and data, I re-flashed the original Samsung image, I did a factory reset. Nothing worked to restore the camera. I went in today to a phone repair shop and they replaced the camera module. That didn't help - it still didn't work. Thankfully they didn't charge me anything for their time which was really nice of them. I get home and restored the CM 11 backup of the working image. The camera still doesn't work and now the external speakers don't work for media files. I was afraid that it was something forgotten to be reconnected by the repair shop, but I can hear the phone ring when I make a call. (I haven't received a call yet so I don't know if it is only on outgoing calls).
Can anyone point me to help or resources for how I can diagnose and hopefully fix these problems? My phone is falling apart and I don't know what to do!

[Update] I solved the camera problem by restoring a backup of the original TW rom. This seems similar to a problem I had with dubbsy's rom where the GPS wouldn't work some times after a flash and required restoring the touchwiz rom to get it to work and then re-flashing the custom rom. Once the camera started working again with the original rom it continues to work with the OctOS rom. Strange but at least it works.
The external speaker was resolved by taking it back to the repair shop. He switched the external speaker module with one from another S4. Putting it back together it worked, but when he put back in all the screws and closed things up it didn't work again. Finally loosening a few screws, getting it to work and then retightening solved it. I don't think it was the original speaker module, but something about opening it up and closing it back up caused the speaker not to work at all. Now it does and I can hear the ringer and notifications agin.
