LG G2 Cannot connect to camera

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...).

Help with modems, proximity sensor, camera and auto rotation

Hi
I got a G2 (D802) the other day and so naturally I rooted and installed the latest CM nightly.
I didn't flash any new modems or kernels or anything like that, all I flashed was the ROM, GApps, Xposed binary and SU binary.
I've come across a couple of issues that I'd be really grateful if somebody could help me with!
1) If I use an app that accesses the camera and then exit the app, the camera will no longer work until I perfom a full reboot.
2) Every sensor that shows up in this app is showing readouts of 0 despite me moving the device around, shaking it, waving my hand over it etc. This results in me not being able to use auto-rotation, accidentally hanging up on calls because the screen doesn't turn off, not being able to play games that rely on the accelerometer and many other issues.
I keep seeing posts saying I should flash a different modem but I'm really not sure which one to use! There's about 4 different ones for the D802 and I don't want to brick my new phone by flashing the wrong modem!
All help is really appreciated! Thank you!!

BUMP! help needed!

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

Broken display after trying to install TWRP on D802 with AutoRec?!

Hi guys,
after finally getting a new screen for my D802 (whole other story) I installed it and it worked great. Next step was to update to a newer ROM and Android etc. so I wanted to try out Lineage 14.1.
I got AutoRec to install TWRP, which went fine until it rebooted. The display started showing nothing but white stripes.
Because of anti-spam reasons I can't link to external websites and I can't find any way to upload pictures so I'm cheating with the link and hope that is okay, if not please delete the link and tell me how else I can show you pictures.
PICTURES HERE imgur.com/a/VcLR3
The first two are during the "LG" boot animation, the latter two are when it has loaded up the OS (I assume).
Did I somehow destroy my new display? I've looked around and found similar problems for some obscure ROMs and such, but it was never the whole display but rather just a few lines to the side, nor was it with such a simple, everyday task like AutoRec that seems to be working for a million people.
Is there anything I might be missing?
Assuming the display actually IS broken and I replaced it again, would the current configuration kill the new one as well? Since I don't have even 1% of screen to play with I don't see myself changing anything back to stock or so.
Thank you so much for any help.
Edit: I just found this thread https://forum.xda-developers.com/showthread.php?t=2680948, do you reckon this is my problem? There are no pictures, sadly. And if yes, how on earth can I do anything with no screen?

Just reflash stock kdz

Thank you, I flashed some stock stuff and the display is working again. I would never have thought it was a software issue. Thanks!

Problem with the camera

PLEASE READ!!
Hello everyone! I have been facing a serious problem for a while now. I get a warning when i try to take a picture using the stock camera app. I can actually take one or two photos but then the phone crushes,a warning pops up and then the phone restarts. I searched a lot on the web but i didn't actually find the exact same issue. Many people complained about this and had a black screen whenever they open the camera app. I don't get black screen but the camera app crushes whenever i try to shoot. I tried all the suggested solutions but they were all in vain. The same thing happens with the front and rear camera. I really don't think it is a hardware problem because this happens with the official firmware and the touchwiz based roms. I had the same issue with the resurrection remix camera(no warning,the phone just restarts) but i found solution with lineage os 14.1 camera!! The camera actually works with lineage os. I ve been using it for a while now but we all know that it is so basic and incomparable with the stock camera.
Anyone having the exact same issue?

If it's not a hardware problem, have you tried doing a hard reset?
This will restore your phone to its initial, factory settings. Thus, any third-party apps or issues your phones is having will be erased.
Factory reset steps: https://www.unlockunit.com/blog/how-to-make-a-hard-reset-for-samsung-phones/

I tried all the suggested solutions in the android forums: factory reset,wipe cache,settings reset... None of them worked.

Did you drop this device or sat on it?
Try to take it to a phone repair shop and see if they can fix it.

Install a third party camera app from the play store and try (install few apps cameras) , if it works it's not a hardware issue, if your camera fails again it is passible a hardware problem.

I m sure it is a software problem. How can i fix that? Don't tell me to do a factory reset. I rooted my device. Is there any solution to do through the app systems or something. Can rooting actually help me fix that? How can i access all the camera related system files?
I hope you understand what i m trying to say

Try a free camera app, a custom Rom or just reflash your software with Odin. If the crash still happens it's a hardware bug, sorry.

I tried to flash with odin and use a free camera app. I had the warning in both of them. I tried many costom roms but the only working one is LineageOS 14.1 but the camera is so basic...

I still think this is a weird hardware bug, but try to install zero camera mod, maybe this will fix it somehow, or try a new micro SD.
