can't connect to camera. - G2 Q&A, Help & Troubleshooting

my lg g2 can't connect to camera and hence force crashes, the front camera works. i replaced the camera by buying a new one, but the issue is still present,
i've noticed something though, when i installed a torch app, the following message comes up - "Due to limitation of your hardware or OS, your device does not support LED Cam light, We will light up your screen at maximum instead."
It also says - "Your LED is being used by another application. We will light up your screen instead."
Any help would be greatly appreciated.
cheers

Try reflash your phone to stock .kdz might help.

thanks the issue is still present in stock kdz
and the same messages pop up with the torch app.

Also as a note, the rear camera also does not work in safe mode.

These would probably a hardware issue then. Since nothing could fix it by meant of software. Did you get a genuine camera module for the replacement? Im afraid its not compatible or at least the module itself is broken. If you happen to consider buying another camera module i would suggest getting G3 camera module as it 100 percent compatible with G2 and also it had a little better spec.

Have you tried running a test with 3845#*802#?

could it be that the replacement camera is faulty? hmmm, i'm not sure. the one i got was genuine though. so im not, i fell inclined to believe it may be the camera flash thats causing these issues.

Sometimes even a perfectly careful assembly could mess up something. Maybe its just a loose cable or shorting something. It could be.

Any solution to it ??? I also have same issue? @salespalace

Turned out to be a hardware issue - despite replacing with a new camera port, still didn't work, - which told me there was an issue with the motherboard. sold the phone off. so no real solution. sorry.

If it's under warranty have it checked/repaired. It may be faulty or the connector may be loose. The danger in replacing the camera yourself is that it may not be the camera but a circuit board fault. If you do not have a warranty and are technically minded I can give a link for changing out or checking connection of the front camera.
Mike
thanks Mike; can I have that link please? where can I buy a new cam?
many thanks

I don't know of a source for the camera off-hand but I'll do some checking.

I have the same problem on my HTC TyTN. Videocalls don't seem to be working anymore (they used to). I've never updated the ROM.
What's odd is that I can't use any of the 2 cameras for videocalls eventhough the main camera works when it comes to taking pictures or making videos.
(I haven't tested the sensor camera since there is no possibility to use it outside of videocalls).
I would think my problem was software related.....
Any idea to fix this?

So far as I'm aware you can only use front cam for video calls. Why you can't make video calls anymore could be troublesome to track down. I suppose a hard reset would be going too far?? (got any full backups? - should have and then these issues are easily solved)
It sounds like the main camera is working normally. The front camera can be used as a regular camera or video recorder and even a web cam. There are a few applications available from Ateksoft that can get these things working for you. The software is not free although they may still have trial versions available:
Coolcamera: http://www.ateksoft.com/
This will also let you know if there are problems with the front camera.
Mike
Thanks for the info!
I've just installed Webcamera trial version. It works with the main camera, however if I choose the front camera, nothings happens (the application seems to not be able to intialize the front camera as it will hang undefinitely...)
I guess my front camera isn't working properly... That sucks as I can't imagine being without my HTC TyTN if I was to send it for repairs (hopefully I don't make that many videocalls).

Mmm.. that's a pity. paersonally I never make video calls but I would be annoyed if I thought it would not work if and when I choose to. Have you tried a hard reset - I know that can be a big hassle if you don't keep full backups but still it would confirm (more or less!) whether it's a hardware fault or not.
Mike
like i sow in other topic this is common problem for many users (within me) , i expect it to be something else than hardware problem ...
same problem here!

[Q] HTC HD2 camera problem, weird color

I'm having a weird color at my HD2 camera.. I'll attach the photo of my HD2 taking picture at something.. does it hardware problem? I've upgraded it to newest official ROM, and even tried SD android build but no luck..
please, I need some help
Looks simular to colours i was getting with mine, I had a mainboard issue i think causing the screen problem like that. I had those colours all the time though. you played with the settings? colour saturation maybe?
nope.. it's just like that.. tried any other setting with no luck..
my friend said it was a camera module error.. and it costs 400K IDR (around USD 40) to fix and replace it..
I have the exact same issue. The color is distorted like that (too much contrast/saturation) no matter if I am in WinMo or Android. I have played around with the settings but cannot get it to look normal. Default settings look like that. And yes I have hard reset several times....
Anyone have any other ideas?
I too have this same issue...I've tried a hard reset and a ROM re-install but the problem still exists...does anyone have a resolution for this issue?
Yes send back to htc for repair.

Sent from my ADR6400L using XDA Premium App
I have the exact same problem.. is it related to the google goggles app? Because my camera works fine before I tried the app.. (my device is htc desire hd but having the same issue)
It did turn out to be a faulty camera module which was fixed under HTC's 2 year warranty

same with me.. only in my case, it's not covered by warranty, and I fix it for around $50..
i have the same problem. and it was also fine at first and stopped working after google goggles. anyone find a solution besides sending it back?
I have same problem with my phone.Maybe to try another camera app. My phone is currently dissembled so I cant test.
Anyone find solution?
Oke I tested my camera more when m phone is assembled. The closest to normal photos I was getting when I was pressing screen in camera area. I always get same picture as first photo in this post. And when I switch to android Froyo 1.5 system I get pink color when run camera.
So people what do you suggest?
What part should I change?
Whole camera or just this square camera module?
Or any other solution...
Grateful!
Please if anyone know solution for this problem and gives me answer.
What replacement parts do I need? Should I change all camera related part or just this came module (looks like little cube) or maybe flex cable??

"Camera Busy" error after update

Hello, I just bought a Moto X Play XT1563 used that has the camera problem.
When you open the camera app it returns the error "Camera busy. Can not start the camera. If this happens again, restart your phone."
The former owner of the handset, informed me that this happened after he upgraded the system.
I already took a technical assistance, the rear camera was changed but nothing solved.
I've tried all the tutorials and tips I found on the internet.
I'm still hoping to be a problem with the system.
Can anyone give me a light, or idea of what that might be?
I'm attaching the dmesg.log (kernel log, I'm currently with CoffeeKernel v2) which is returning some errors on the part of the camera.
I thank you.
Sorry, message has been translated.
same problem here.. anyone knows how to solve this?
Did u ever edited build.prop for any reason??if yes,just remove the lines u have added or restore the original build.prop file.

After some test I think the problem is something with the front camera, when I mount the front camera sometimes work but not ever, in fact when I remove the front camera the main camera allways work. I verified the grounds but I not found nothing.
Another option it's a problem with the firmware.

When you removed the front, did the flash (led) work again?
Mine currently does not work at all, not even the flashlight.
Maybe a solution
Guys, I've found that the problem in my phone was the flat of flash. It was a little to far from contacts . So I removed the clue in it's back and added a little piece of plastic. And assembled the phone again. It worked just like a charm.
I hope it helps you. (Sorry by the bad English)

I just disassembled the phone, disconnected back camera cables and reconnected againg (remember to pull the locker down after reconnect) , I needed to do it 2 times because the first attempt did'nt work. YOu can try the camera witthout put the screws. Reassembled and now no errors!

I've done a little mod and resolved my problem. The led's connectors were not touching correctly the connectors of the board.
I corrected it by sticking a little piece of plastic below the connectors of "middle frame", so it became a little popped out and solved the problem.
I hope have helped you guys.

No. The blue one. I've lifted a little the connectors and put a plastic piece below it.
The first time the piece, got loose, the second time I used a dual face tape, to put it together.

LG V20 H990DS front camera not working

The front camera on my phone does not work at all. If I chose the front camera, the phone tries to witch to it for about 3 seconds, then it just switches to the wide-angle back-camera.
Is there a solution for this?
The phone model is D990HS which I bought fron eglobacentral.
Can it be that they flashed a wrong ROM on it before sending it even though the phone was supposed to be new?

Yes, it was a hardware problem. I changed the front facing camera and the issue was gone. I boight the front facing camera from aliexpress for about 8usd, I think. replacing it was easy too. There is instruction for disassemblying an LG V20 on youtube .

Rear camera issues/not detected

Hello Team,
I've had my Essential Ph-1 for several years and loved it. Recently I replaced the battery with no issues. However, I notice that since replacing the battery, the stock camera app would not launch with an error initializing the camera, and it said to restart the phone. Rebooting the phone made no difference.
I opened the device back up and carefully checked all the wires and connections, and they're all tight and nothing looks cut, cracked, or disconnected. I tried a third party camera app (OpenCamera), and it worked fine on the front facing camera, but the rear camera was in black and white only. Since then I have tried factory resetting and re-flashing the firmware, and now the front camera works (in third party app) but the rear camera is not even recognized and I don't get an option to swap cameras.
Any suggestions? Is there anything I can check to troubleshoot this further?
TIA!

As it's happened at the same time as battery replacement you'd have to think the two are related. Possible try a "simulated battery pull" to ensure camera is powered down, that is a force restart, press power button & vol driven together for 15secs (I think). If this doesn't work try disconnect/reconnect any components related to camera. Only other thing I can think of is the camera or related component has received ESD damage form static electricity (most likely a diode or small IC), maybe you can find a cheap bricked or damaged phone for spares, if camera module expensive, assuming it's the camera.
Appreciate the response. I think you're right. I've forced restarted and flashed it back to stock, and while the stock camera doesn't work, I found that if I use a third party app (such as OpenCamera) the rear camera works in Greyscale only (not in Color).

hummmm ... Yes, hard to say for sure boat seems like some hardware issue on the color camera, hope you can find a simple fix.
Appreciate the followup. After looking farther. I see there is a hairline crack in the camera. I bought a parts EssentialPH1 off of eBay for ~$50 and will give swapping them a shot.
