Camera stopped working

The camera has stopped working randomly. The only thing I could think of that might of caused it would be the phone some how shut down when it was in my pocket. When I start up the camera app it immediately closes. When I attempt to use Google goggles, it says cannot connect to camera. What can I do?

First off you can give us some more details as to what software you are running. Are you on a stock Sprint ROM? A custom ROM? Did you install any software and then notice this change? Does this happen 100% of the time?

I'm running the stock 2.2 rooted odexed rom. Stock kernel. And haven't installed any new software to cause this...

I've cleared cache, dalvik cache, camera app's cache and it still doesn't work...

No one has any idea? Has this ever happened to anyone else?

It happens to me on both ava stock 2.2 and now netarchys 2.2... I have to wipe everything to get it back for a few hours... it just did it to me again do you have netarchys fps fix?

This is the craziest thing ever. The camera has returned to working after 10 hours of not working. I didn't do anything to get it to return. I will be continuing to monitor the camera to see if it happens again... This is the first time it has ever happen and the first time I've been on a 2.2 Rom for a significant amount of time.

This just barely happened to my phone too! Grrrr!!!
I'm running Fresh.02 + I tried flashing several kernels to see if it would fix it but none of them helped.
kernels I tried, latest versions of: kingX, snap, netarchy
Will try to do a full wipe and flash the stock 2.2 rooted w/o any fancy mods. <--- ok this fixed it!

Does installing the 3D Gallery app cause the Sense camera app to randomly stop working?
I'm getting the same problem again on a different ROM.
UPDATE: I've uninstalled 3D Gallery & cleared data on the Camera app and it still doesn't work.

i am having this same problem. have flashed several roms with no fix. cannot pin point when this happened either. really frustrating. ive done reboots, wipe, you name it.

happened to me

Hi guys
Any luck with this problem? I'm using a rooted xperia neo running [email protected] #2 with an unlocked boot loader - I've used Google goggles many times before and then today its coming up with "Cannot connect to camera. You may need to restart your device" and yet the camera is working because behind this pop up I can see the image that the camera is seeing. I've tried to take a screen shot of this but the screen shot uses the camera and therefore I blanks out the image through the back lens.
I've also uninstalled the app and reinstalled it - cleared all Dalvik cache - as well as moved it to SD and made it a system app - none of these trials have made any difference.

Are you sure there are no problems or known bugs with the rom you are using? Have you tried reflashing your rom? (it might be a pain to do, but something in the rom might have broke and it can help to start fresh).

I never post here but I have had a problem with my phone's camera that I fix by some random thread I found a while ago so I thought I would share what helped me. The thread stated it is something to do with the camera's connection to the phone and sometimes with drops or bumps of the phone it becomes loose. All I had to do was turn the phone face down, put my thumb over the camera and press down with some force. Not enough to break it but just to reseat the connection. After that, restart the phone. I have done this a few times and it has been successful ever time. I hope you guys have the same success.

That is correct, in some cases i have found the camera has come unseated. but it could also be the board.

Camera has stopped working

The camera on my HTC Excalibur has stopped working. It's not just the camera button, because the button still works as SYM. I get absolutely no response when I try to run Camera.exe as well.
I am using 3VO.3.50.033010 ROM. However, I have tried a couple of earlier ROMs and had the same malfunction.
Any help is appreciated.

Probably is hardware , since you have flash other roms and hard reset

hey could you fix the issue? Im having the same problem, I tried using the camera and a pop up came up saying it could not load the camera, i can use the camera since. I already did a softreset...
thanks!

Do a hard reset and see if that helps

Little late, but continuing...
I had almost given up on the issue, but since I found this topic, just wanted to try.
So, my camera stopped working. First, partially, showing this message that it couldn't be loaded, then completely. After all soft and har resets I tried, all ROMs flashed, nothing seems to have helped. Any idea on what I should do? Should I just assume I can't fix it?!

Do you have other problems with the device, e.g. run out of power easily?
Can you still operate WLAN well?
Often the battery of older devices is aging and slowly getting dead.
If not, then:
As already proposed: try hard-rest first.
If you are on a cooked ROM: try with a shipped ROM.
If that does not help you may need to dis-assemble the device (not easy) and clean up the connector from the camera to the PBA. Still not helping: replace the camera - or the device.

So...
well, as you mentioned, my battery is easily out of power, but i guess the problem is the cellphone cause the two last batteries i recently bought have no difference in performance to the one that came with the phone itself. after 8h it usually discharges completely. disassembling is something i'm not sure i'm doing, but, thanks for your reply!

I747m screen problem...please help!

Ive searched everywhere and can't seem to find anyone with a solution. Ive found a post with the same problem but no solution.
So yesterday my s3 started having problems waking up. Meaning when I lock it usually you bring up the lock screen by pressing the power button or home button. Problem is when I press either one, screen doesnt come on. The buttons do. If I tap the screen I can hear the ripple effect but the screen doesnt light up. I have to keep locking and unlocking till it finally works. Averege of about 6 tries. When I get a call most of the time the screen doesnt come on either. I can still answer since I know where the slider is. When I do turn it on everything works perfect. No flickering or any other issues. When it boots it works perfect...never fails. Just when I lock it.
I tried restoring already, thinking its a software issue...still does it. What piece of hardware could cause this? I'm stumped. Please any advice would be great.
I'm not rooted and running 4.1.1 oem rogers software.

My guess is that you have something draining all your RAM or being hard on your CPU. When you restored, did you factory reset?
You might have to backup your stuff, factory reset. Test it, if it still does it, bring it up with Rogers for a replacement. If it doesn't, reinstall your stuff until you find the culprit.
You could troubleshoot it also by uninstalling the latest apps you installed.

Like I said...Already did a factory reset. Meaning All apps were gone. Started fresh. Even without going through the first setup (setting up google account etc etc) if I lock the phone its hard to wakeup.
Phone is out of warranty so no go there....
I'm just not understanding what is causing it. I know the screen is fine...buttons are fine...everything points at a software problem. I found a post from a while back where someone was having the same problem....no solution was posted though. I even took the phone apart last night thinking a bad connection or something...disconnected the screen and reconnected it...didn't do anything.
If the screen was going bad wouldn't I have issues all the time? Once I wakeup the phone it works perfect...no flickering or anything. When it boots (which I've done like 30 times between today and yesterday) the screen has come on every single time perfectly fine. Everything tells me it's software related...but after doing a factory reset and running original firmware it seems as though it must be a hardware issue...but which component.
I know the phone wakes up when I press the buttons...I can see the menu and back buttons light up...and if I tap the screen the ripple sound is there...just the screen doesn't wake up....till I try a few more times....very frustrating.
Thanks Again for trying...if anyone has any ideas....greatly appreciated. I'll try and find original Rogers firmware and install with odin...see if that works....

Sounds indeed like software issue. I'm not so sure what would cause it on stock rogers though.
Either way, you can find the stock ROM on sammobile.com or on this thread: http://forum.xda-developers.com/showthread.php?t=1822308
You'll need Odin to flash it. (It doesn't trigger the flash counter)

Did you buy your phone with a credit card? Some cc's have warranty built in. Mine doubles what the manufacturer offers.

Thanks for the link. I will try it tonight and post the results. Really hoping it works.

I downloaded the newest firmware. 4.1.2 official rogers. Problem persists. Must be a hardware issue. Thing is what could cause this? Is it the screen...is it the gpu? I imagine if its gpu the phone is only good for parts as I imagine its part of the motherboard. Oh well...might be getting the s4 sooner then planned.

If you're down for a little test, you could try with a custom ROM.
Use the link I gave you and flash pre-rooted Rogers' ROM. From there, install TWRP (or cwm) using goomanager (from the Play Store) and flash a custom ROM as per their instructions (Don't forget the Gapps).
Before anything though, make a backup
Never know, might save you some time on that S4.

Thanks. I might try it. Dont think I have too much to lose at this point. I always try and keep my phones nice so that when I get a new one I can sell the old one for good money to help offset the cost. This really messes with that system as the phone isn't worth much now...just bought an extended battery too...was planning to keep it for at least another 6 months.
Sent from my SGH-I747M using xda app-developers app

So just a quick update. For no apparent reason the phone started working fine again. It now turns on and off just fine. I'm not going to mess around with it anymore. That's really bizzare. I'll give it a couple days and will report back if it continuous to work fine or if the problem comes back. Thanks for the input.

[Q] Samsung S3 Camera Fail

I tried searching the forum, all i found were people telling each other to take out the battery or send it back to samsung...
if you find a link that covers my problem, i humbly apologize please direct me to the thread.
okay:
i bought an s3 off kijiji (craigslist equiv) the camera does not work.
I click the camera app, app loads, picture is black, then a dialog box saying camera has failed pops up, app crashes. Repeat.
So I bought a new rear camera, i put it in and guess what! same problem.
I tried every software thing i could think of (post and pre new camera). I tried different roms, CM/PA/STOCK Mod, no luck.
I tried going into the firmware service menu with a touchwiz rom and making the two firmware numbers match as in this thread:
http://forum.xda-developers.com/showthread.php?t=2006128
I tried going into app settings stopping the camera app and clearing the cache.
Now i am out of ideas and i seek better men/women to help me.
I have a new camera, i just bought, and the old camera.
oh before i forget: I saw the old camera work only once since i bought it, it loaded up randomly and was all glitchy green lines running down the picture. It loaded up with the front facing camera part which to me worked fine, then when i went to rear camera it did the glitchy ****.
sorry if my post is hard to read, im tired, and frustrated with this thing.
the phone is sitting here all dissassembled waiting for the next step.
are there any diagnostic tools i can dl that checks the motherboard and each camera (front, and back) individually?

nothing huh?

Sounds like hardware failure to me man,. sorry to say it. Have you used odin to bring you back to full stock? did the device come rooted?

There are 2 tests you could do (though they're probably the same). This requires you to be on a stock ROM.
From the dialler, enter:
*#0*# General Test Mode
*#7353# Quick Test Menu
Then, the choices are obvious.

Look at the board closely. Examine the traces on the board coming from the camera connections and where the camera connectors plug into the board for any signs of a white powdery substance. Dendrites will form on circuit boards and short out the associated electronics. If you don't have a warranty, it would be worth it to get some high grade isopropal alcohol and give the board a good rinse. You may even scrub the affected area with a good clean tooth brush and then flush it again. Let it dry thoroughly and then reassembly it. It would help to get some of that canned air and blow it off as well. I've had that work more than once on delicate electronics that have gone south.

using odin to bring back to full stock is the only thing ive yet to try.
When i got the phone it wasn't rooted.
I guess the last thing i will do is try the new camera with ODIN stock.
i really doubt it would make a difference.

that is the first thing i did actually. i was afraid it may of been water damage. the phone is taken apart infront of me right now. I dont see any sign of white spots. it looks clean as a whistle.
I really dont understand why its still failing even with a new camera.
DO any of you know weather If only the front camera fails will the entire camera app fail?
Also the front camera and the proximity sensor are tied together as one unit. and the proximity sensor works fine.
also ive mentioned that ive seen the camera work once. so ....I just dont know...

It's either a hardware problem (other than the camera itself), or it's a software problem. I would revert to stock & run one of the hardware tests I mentioned previously. That should rule in or out a software cause.

Update:
I used :
http://forum.xda-developers.com/showthread.php?t=2363882&highlight=unroot
to unroot and go full stock...
still nothing.
i did those tests from *#7353# Quick Test Menu
it fails on both rear and front camera..And the REAR camera is the new one?!?!?! wtf.
does anyone know if one camera does not work they both dont? (since i replaced my rear camera, it may of been the front camera this whole time that didnt work.) i wish i was rich so i can buy another phone to test my hardware with.
do you think its a mainboard problem? - i guess thats all that is left.....

I experienced the same problem last few days. It started the next day I rooted the phone. I tried all the ways I found on the net, none worked for me. I even formatted the internal drive. Problem was still there.
Then I flashed Task650's AOKP rom and surprisingly the camera started to work. So I guess it maybe as stated in the forum, the driver, for some reason, was not in the correct folder. I guess flash any 4.2.2 rom will fix the problem. I am now running on liquid rom. Hope this can be a little help?

ive been on 4.2.2 PA

out of pure desperation i tried this method.
and it did not work same old message
either
gallery has failed
failed to open camera
worth mentioning:
when i am in stock rom, there is a feature that detects your eyes to make sure the screen should stay on. It works. It says it uses front camera to achive this functionality but...alas my camera does not work.
What can i do to help you help me.
im totally at a loss for words i dunno what to do

I was experiencing the problem last week on Stock Rogers ROM 4.1.1.
I tried restarting, battery pulls, formatting and taking apart the phone to disconnect/reconnect the camera.
Nothing worked and I was convinced it was a hardware problem.
As a last resort I flashed the stock Rogers 4.1.2 update and the camera started working again.
I flashed back to 4.1.1 and the camera stopped. Not sure what was causing the problem though.

If your on the new 4.1.2 bootloaders and running 4.1.1 the rear cam won't work, flash the old lk3 bootloaders.

It looks like a software problem
I had the same problem.
Rear and front Camera gave SOMETIMES "Camera Faild" error.
It looks like a software problem which uses the camera or the flash.
Many users saying that the problem is resolved after signin out from Skype.
For me the case was the Flashligt software. You can try to find out which software can be the cause.
I hope this is the problem and you all will find out the software which causes the error.

No solution Camera failed Samsung s3
I still have a problem with my Samsung i535 s3 camera failed .
I've tried all the options of the application manager app stop clear cache , install 2nd app app to run CAMERA and nothing. I even replaced the physical camera from another vorking S3 i747 and again nothing , reset wipe cache system start from scratch and still no go.Changed proximity sensor still no go, another SS3 Basically had to swap parts and test it to no good
Don ` t have a micro sd card , and I spent 3 days at various forums to find out how to fix the problem .
S3 is not under warranty and service shop could not help me. I deleted all the apps that use the camera as Skype and flashlight and again nothing , Camera failed .
Otherwise my S3 i535 runs on stock rom not rooted and hasn ` t been updated stilruns on 4.1.2 didn ` t go for 4.3 update . Everjthing else Works fine ekcept camera.Somebod

Camera not detected at all

So issue started as follows:
a. For a few days, I've noticed that camera will give very blurry photos and videos. I tried a few things (including cleaning laser/camera lens with a cloth), but it wouldn't work.
b. Decided to restart phone today and see if that helps (turn off and on right?)
c. I now get error "Unable to start the camera" when I tap on the camera app.
I have tried the following:
a. install 3rd party app - won't work
b. restart phone (multiple times) - won't work
c. clear data/clear cache, disable, enable, remove permissions and allow permissions for Camera app - won't work
d. reboot phone in safe mode - won't work
e. Go into diagnostic mode using #*#*3434*#*# to test camera. Guess what, there are no options to test camera!
f. Go into diagnostic mode and test flashlight. Flashlight won't turn on anymore. Also, I found that the system's flashlight app is gone.
All this leads me to believe that for some reason the phone is not detecting the camera hardware anymore. I'm out of ideas. I bought the phone overseas, and local HTC told me to return it overseas or pay a handling fee of $100 and they'll look at it, but will probably not be able to do anything anyway.
Phone is just a bit over 1 month old.
Any ideas?

I'm having the same problem. I'm rooted on unlocked HTC 10 on stock 2.41.617.3. I'm S-On. I've tried force stop and delete cache and data. Tried safe mode and tried a 3rd party camera app. I just got by phone back from HTC to repair the camera and it worked before flashing the January security update and rooting it. Afterwards, I now get "unable to start the camera"

So, I completely wiped data and reset factory settings, but camera still wouldn't start.
Flashed phone back to Taiwanese version, and it's now working, but original issues are back, i.e. blurry camera that can't focus on anything. I restarted phone a few times to see if it would go back to "unable to start the camera", but it's still working, just blurry and unable to focus. I'm still going through the various updates now. Have notification for Nougat. will try that and test camera again.
[UPDATE]
Interesting update: So, I upgraded to Nougat just now, and after restarting, I tested camera, it's not working anymore. Here's my speculation: 1) camera module (hardware) is broken/fkd up/stuffed, but only partly? Whereas Android 6 will let it work, but blurry and no focus, Android 7 just won't let it work at all. That's just my theory that makes a little sense atm. Anyone else?

I think you are correct, i would send it for warranty (if you still have that)
Good luck !

I did a hard reset and the camera started working again.

Lucky! Is yours ANY blurry or is it fully functional? Also, if it stops working again, check whether your flashlight works (mine wouldn't/isn't).

It was blurry when I purchased it used. That's why I sent it back to HTC since it was under warranty. It looked like it was a bad auto focus module, although HTC never said so. Fixed and was working well, then today (after the reset I posted about), then today it stopped working. I'm going to RUU tonightor tomorrowand install apps one by one. It seems to be softwa rerelated.

I'm sure it will work if you go to android 6, but it will be blurry. It won't work after you restart in android 7. That's my experience

My wife's 10 was having this issue. Neither a factory reset nor an RUU helped. But randomly it just started working for her. There were app updates from Google for photos and chrome but I have no idea if they're related but nothing else changed. Really strange!
Edit: a day later the camera is not working again.

I've been experiencing the very same problem and the only thing that helps is hard reset or RUU. It doesn't always work on the first try, but after 3-4 attempts the camera starts working perfectly for a period of time -- sometimes a week, sometimes a month and a half (my personal record, which was set a few days ago, when camera died again). Then I always have one day of the focus getting disabled followed by a complete shutdown with all the symptoms described by OP (no flashlight icon, 'unable to start' message). Has anyone found a permanent solution to this problem?

I have the same problem with my htc

I have the same problem on a non-rooted Verizon HTC 10... the camera app won't open, the flashlight won't work, the camera shortcuts disappeared from the top Nougat menu, and any other app I try says it can't find the camera.
I'm unable to find any troubleshooting or debugging methods yet... any suggestions? I have Android Studio but I haven't learned much of it, I'm wondering if Developer mode or the Studio USB debugging can help...

A few things that seem to have helped some people are:
removing SD card and restarting the phone without it;
clearing camera app's cache;
uninstalling all 3rd party apps that might be interfering with the camera;
RUU-ing the phone with an official firmware (you don't need root or S-OFF for that, as long as you don't try to downgrade from Nougat to Marshmallow).
Nothing but the last method worked for me. Though it doesn't do the trick every time and even when it does, it is only a temporary solution, as the problem keeps popping up again after a while. Last time the camera in my HTC 10 started working without any software interference from my side: I went on a hike in cold weather and, as I hypothesise, something about it (temperature differential? pressure change?) restored camera functionality for a couple of weeks, after which it died again. This incident led me to believe that this is a hardware problem and the camera module simply isn't securely connected to the motherboard in our phones or something. My wild guess is that RUUing might sometimes help simply because of the heat rewriting firmware produces.

Oh *smack* sorry I forgot to mention that I already tried clearing the camera app's cache, wiping cache from recovery menu, and factory resetting the phone.
I think it's a hardware issue since I think it got a little wet from sprinklers and I read the phone isn't water resistant, and also that the camera module is flaky anyways... Verizon accidentally cancelled my insurance without telling me and I haven't seen yet that HTC covers it on warranty.
I'll try these other things you suggest, but do you think it would be worth trying to have HTC repair it? It'll be worth it for $350 or less, or I could try a local shop, though I think they'd just do the same thing I would (research it on Google, buy the necessary repair parts, then painstakingly fix it), but I've seen in repair videos that this phone is very fragile and difficult to work with, so I'm not sure all that time and effort would even be worth just buying a new version outright, and I'd like the phone to work for the eclipse!.

Same Problem here, since Saturday... [emoji85]

I actually went to a repair shop about a month ago and was told that they were certain part replacement would leave significant marks on the metal body =/ If you carry the phone in a full case, I guess this should not be a big problem. AFAIK, an official HTC repair shop would just replace the phone under warranty in cases like this due to how low simplicity of disassembly was on designers' priority list when 10 was being sketched out, but you're saying Verizon canceled your warranty?

I also face this unable to start camera.
My software no is 2.51.617.11
I live in Myanmar (Burma). No one know this problem including HTC Myanmar.

Apparently there are a handful of us who have faulty cameras. Haven't heard anything from HTC. I have tried everything listed here and more. No luck. The only way my camera works is on older firmware (1.9.xxx.xx) and running Marshmallow.

well my htc 10 started playing up today, camera wont start when you touch the camera app on the screen..ive had this phone for 9 months , my warranty expires in march 2019, ive tried all the above methods none worked, phoned HTC uk up and they said to send it in..i hope they replace it with another unit ?..if they do replace it with another unit will the wrranty be transferred over to that, ie expire in march 2019? i also noticed that the flashlight app doesnt work it just says on screen "loading"..

I have the exact same problem, tried all the suggestions, but still it says 'Unable to start camera'. I even opened up the phone, and replaced the camera with another HTC 10 which had water damage. Problem still exists, which leads me to believe that the camera isn't the issue, it might be the mainboard it's connected to in combination with Nougat? The other case can be that the broken phone I got the camera from might have the same problem.... allthough I think that's unlikely. I'd like to order another camera to make sure its not that, but can't really find one. Anyone got any further with this issue?
