LG G2 Cannot connect to camera - G2 Q&A, Help & Troubleshooting

Had this phone for about 1 week now. Everything been fine until today. I tried to take a few pictures, but I couldn't. Received an a pop up with "Cannot connect to camera" I'm not sure what's causing this issue, I cleared the data/cache on it and still occurs. Is there any solution to this issue?
Thank you.

I have exactly the same situation.. But it's weird - ported LGCamera works without errors, other apps (market or aosp based) throw error. Sometime clear app data help, but only sometimes..
It could be hardware problem?

I've had this happen when I was on an older CM11 nightly.I did have to preform a clean install to fix the problem.

18/03? It didn't helped.. I was testing old and newest ROMs - same situation I think it could be some hardware problem - currently I have version from Singapore build at 02/2014
EDIT#1
Weird.. I will go back to stock - test, then install custom ROM.. Something go wrong - when I'm using ported LGCamera.apk in CM/Slim/PA it's working, other camera apps - don't..

I guess I found out the issue of why it was being caused. I also have a Nexus 5 and both had the APP Flashlight by Go Launcher. Seems to me when I downloaded and used it couple of times it caused my camera not to work on both phone. Uninstalled it and now it's working fine with now issues. I'm not sure if you guys also have a flashlight app, but maybe you can give it a try.

I got a replacement g2 from my insuarance and from the box mine done the same thing i tried every app i could find one day i flashed a diffrent rom and was bored. Clicked on my cam and it worked went back to my stock backup for my updatez and it wouldnt connect found out its was a software isse broken software from the factory i put a new stock rooted rom on and good as new. Mine was down. For about a month whrn i notticex what was wrong i thouvht i had a hardware failure but it wasnt there is always a chance of a bad cam but also some app like certain flashlights do take over your hardware if uve rooted and the phone is new goback stock unroot and have swapped

I'm on stock KK right now = 0 problems, so I think it's not hardware. LG camera and other apps always working fine.
Now I will go back to AOSP and test apps again

Hello,
Did you go back to aosp ? Is the camera ok now ?
Thanks

Here's a thought. After a new rom anybody feel there is a dial pad code to bridge the connection gap.

help, question

THANKS,I got the same problem and after I deleted the Go Flashlight the camera worked again!

Same issue. Go flashlight solved thanks to this thread.

Having similar issue. Flashed a new bootstack and camera stopped working. Factory reset, fresh install tot, then kdz, then cloudy g3. Camera still force closes and other camera apps can't connect. I can take one picture after a fresh install (which I did three times flashing from tot...).

Camera force close

I am having some trouble getting the camera working on a mytouch3g I have been working on. I have Engineering SPL 1.33.2004 installed with CM-recovery 1.4 installed. Have tried several 32B roms but always get a force close. Have wiped, restored nandroid backup, used clean sd, and even tried pushing the stock camera and 3rd party camera apps. Is there something I'm missing? I have rooted a few Dreams, but this is the first Sapphire I have dealt with. Any suggestions?
try flashing the stock mytouch rom. its on here some where. if that works then just try a cyanogen rom. i refer the 4.0.4 rom. if this works then you had corrupt files on dl. if this is the case then try using a dif os. if continues then your sd and or file reader is trying to filter content. so use something else. let me know. rockin...
Thanks for the reply. I have tried cm 4.0.4 as well as several of the 32B roms from the Sapphire board. In fact 4.0.4 is what I flashed it to as soon as I finished the rooting process the first time. The camera worked fine that night, but has since crapped out. None combo of roms/spl/radio seem to do any good. Even wiped, and unrooted w/ sappimg.nbh and started over a time or two. Then I read earlier someone on the Dream board had a similar problem, and fixed it by re-formatting SD. So I gave that a shot (even used a different SD that is known to work fine) but still no luck.
So now I have put the phone back to stock. I figured since every partition we change by rooting has been wiped and rewirtten to it's original state, it's best to just call it a hardware issue & have t-mo swap it out. I don't see anyone else having these kind of issues on here. So I'm thinking this phone must have met the floor somewhere between the time I flashed it and the time camera issues started. Nothing else can seem to explain it. Hopefully I'll have better luck with the next one.

Hate to say bro, but ya has to be hardware. Everyone has messed with cam software and had success. So you have done right and reverted to stock. Send that bad boy back and get a newer exchange. Sadly to say my orig. spl was broke and had to send back. I tried talkin tmobile service techs thru the steps but they only were like "ahhhh ummm" lol. do the dew and get a newer hardware softer g2. fosho. . . . .
Yeah that's what I figured. At least the folks at t-mobile didn't give much hassle. It was within the 14 days so they were pretty quick to agree to the swap out. New one will be here next week, and I'll give it another go. Thanks for the help.

[Q] Both cameras not working

Bought an S4 last week. Everything looked good, I tested the sound, vibrate, gps etc and it all checked out. However, stupid me didn't check the camera (I know I know).
So the whole phone seems to run fine, but the camera (front and back) can't be accessed by stock or 3rd party applications. (Usually "warning Camera Failed" or something similar). I've factory reset, cleared cache and everything. I even installed the nandroid backup from a working phone, but the camera gives the same issue.
Because it's both cameras I thought it had to be software, but after all the resets and cache clears I'm starting to lean toward hardware.
Can someone give me an idea where to start? Would it be camera connectors or motherboard? Is there a sensor that may be causing this? I'd like to get an idea before I start gutting my phone.
Thanks.
Try this if it works for you?

If this does not help, clear RAM with a ram cleaner and try starting the app again?
If that does not help either..flash stock rom via oding
If that does not help..turn the phone off..charge till 100%..turn the phone on..clear the ram..and start camera..
Sent from my GT-I9500 using XDA Free mobile app
Had this same issue a while back. What solved it for me was to re-flash the stock firmware. I too tried a nandroid backup, it didn't work but the flash did.
Turns out it was software related.
I installed a few stock firmwares that didn't fix anything. I didn't want to wait the 2 hours to download for free from Sammobile.com, but eventually i bit the bullet and got the appropriate (latest) version of my phone. After the reboot it was solved.
Granted, I tried many different firmwares, and some had the same name as the official firmware that i downloaded from sammobile but it did the trick.
Thanks for the pointers

waiting for some help
Flash the ROM again to fix your WiFi. While the ROM may help, I believe your camera problem is a hardware issue. You'll have to replace the camera module.

ok i just updated 5.0.1 . and how to flash rom via odin?
Flashing a custom ROM won't help fix your WiFi. You need to flash a stock ROM through Odin, and there are threads in the S4 forums which explain how to flash a ROM. Please use the search engine to find it.
Same Problem...
Just noticed this problem 3-4 days ago. I've done a factory reset and also tested a known working rear camera in my phone - I still get an updating firmware message or can't connect to camera message when I open the camera app. Also, the flashlight won't work and disappears from the pull-down menu in Lollipop. I'm unrooted on an I9505G (GPE S4) running 5.0. Not having any other issues with the phone and have tried re-seating the rear camera on the pins over a dozen times. Cleared cache /data from the camera app, uninstalled upadates, etc. I'm stuck. My best guess is either the board, or software related and I haven't figured it out.
With the OP, once firmware had been ruled out as a problem, the only thing remaining would be a motherboard issue. He had already replaced his camera module.
i just want my camera to work no matter wifi work or not. i m stock lollipop
so kindly suggest me something for camera. btw today i will try to flash ro
Take your S4 in for service. If you've updated the ROM and still do not have a working camera, you have a problem with the motherboard, not the camera module.

Oneplus Two Camera issues ... Hell lot of Issues

M facing really weird issue with Oneplus Two Camera.
1) Sometimes not frequently when I open camera app the screen is black and it crashes with an error stating "Camera unknown error".
At tht time if I use other camera apps i.e. Snapchat, Google camera ,etc..they show black screen too.
Even Flash doesn't work at tht time.
So I hve to restart to solve the problem.
2) When in a dark room or so, when I take picture with flash mode on...the camera screen goes blank and I hve to lock and unlock it to solve the problem. But if happens again when I take another shot.
Is there any solution ? Do I hve to worry ? Is it hardware or software problem and if its a software prob...will it damage my camera hardware or any other ?
I really love this phone ...so even minute errors bugs me
Do I need to replace? ...I don't want to spend my time replacing it coz I hve already replaced it ...I mean ..I bought it from Amazon India and due to a small dent on my OPT on the right upper corner I replaced it and it took me 15 days with lot of calling at Amazon ...so I don't want to do all tht again
Please help
I am on Oxygen OS 2.1.0
Rooted
Titanium restored from a backup of my previous phone I.e. Nexus 4 <--- is this causing the prob in any case?
Have you tried doing a factory reset? Did this happen on OxygenOS 2.0.1? Have you tried other camera applications (google camera) to see if the issue is software related? Do you have a custom recovery?

I am rooted
with custom recovery (TWRP)
Oxygen OS 2.1.0
Nope i didn't try factory reset
and yes when tht problem happens all camera using apps hve black screen after reboot everything works
I own that device too and I am not facing any such issues but here is a fix -
If you are rooted clean flashy the ROM
Non rooted -
Wipe cache partition from stock recivery
And most likely I think the problem is titanium backup of previous phone
DARK SIDE™

i just flashed exodus, stock kernel, opengapps, reistalled my titanium backup, and everything works, no camera issue. so i doubt it's a titanium problem, either... but sorry, no idea how to help
Even after factory reset
Not rooted phone. Did factory reset in recovery mode and tried third party camera apps also, still problem persist
This happens for my OPT too. Whenever I try to take a shot in the dark, it just froze. Until I lock and unlock it again. Weird!
I have met the issue 2 as well. When I take picture under dark environment, the screen will be dark and I have to unlock it again. I am using oxygen 2.1 stock camera app. So I think it should be software bug.
One plus 2 camera issue
I was also facing the same issue but now it is resolved.
Steps. Before clicking a pic in dark just maximize your brightnessto 100% and off the optimization of screen in display.then click a pic..the screen wont get dark..and tje picture will be clicked.i hope it will be resolved in future updates with low and automatic brightness too

Camera not working after root/xposed

I have an XT1644. I rooted it and installed Xposed about a week ago. Out of nowhere, today the camera no longer works. I have not installed any new apps or done anything else to the phone. When I open up the camera, the image is all black and the onscreen buttons are not responsive. I have to wait a bit and then it says "camera error camera must be restarted". I have rebooted into safemode and factory reset and the problem persists. Anybody have any idea whats going on?

I flashed stock and that fixed it, but then I again rooted and the problem returned. If I boot into "factory mode" the camera works. On safe mode it doesn't, so I'm guessing it's not a hardware problem.
i had this problem yesterday.
Rooted no problems, Installed Xposed stable version, and then out of the blue after 1 day my camera wasn't working.
Even after i disabled the modules it still was not working.
I had to restore a backup i made the night before....

I fixed it by flashing the newest stock firmware. The old stock firmware was not only messing up the camera, but other things as well. Ever since I did that, I've had 0 problems. Rooted and Xposed have been working just fine for weeks. Give it a shot.
roygbiv859, where do you get the "latest firmware" and how to flash it?
I am hitting this problem and my phone says software is already up to date. Same thing as you guys -- camera and flashlight only work in factory mode.
I have Xposed and root as well, but I remember things used to be working all together.
I noticed that in "factory mode" cellular network does not work, and battery never charges, otherwise I do not really mind running in that mode.
I saw a version number "MPJ24.139-48" at bottom of status page, is that the firmware number? Looks like I am already on the latest.
