Rear camera/Flashlight not recognized - G3 Q&A, Help & Troubleshooting

My rear camera suddenly stopped working. My phone didn't get any hurt in nowhere, just suddenly it stopped working. I was takin photos since 10 minutes before, I locked the phone and I noticed that Torch tile disappeared. I thought it was a bug and I didn't care anymore. The day before I noticed that even rear camera stopped working, I was trying to take a photo but the "change camera" (from front to rear) disappeared in every camera app I was using, camera apps opened by default with front camera opened. I tried to reflash ROM thinking that it was a ROM problem (even if I was using the same rom since months ago and I've never had any kind of problem), no results. Reflashing everything starting from stock firmware, no results. As a last hope, I tried to replace the rear camera by buying a new one, but the problem it's still here. Could someone that experienced the same problem, tell me where the problem could be? Or maybe some possible fixes, every kind of help is appreciated. Thanks.

Same
I have the exact same problem. After wiping the cache the rear camera is recognised and I am able to take a picture with it (which is not saved into gallery) but about 5 minutes later the option to switch to rear camera has gone and all camera apps (including social media such as snapchat) is stuck on front camera. This leads me to think it's not a hardware problem but rather that of software with which I am running cm13 nightlies that I have updated every day for the past week in the hope it will be patched.

I have this exact same problem on my d855 too..!
Sooooo frustrating, I've been looking everywhere for a fix, tried full factory reset the other day (I'm running full regular stock with no root or anything), and sadly that didn't work either... I'm glad to read someone has tried changing the camera hardware, cos that was I step I've considered taking, but I now know would be a waste of time and money...
But still, the problem persists..!

I don't think that's a software problem simply for one reason: I'm on the same rom and kernel since months and camera worked fine. It stopped working suddenly with no reason.

Yeah now you made me understand why the camera worked for some minutes. I'll try clearing cache after installing new camera module. I'll report the result. Thanks anyway.
Edit: It's not working. At first boot, systemUI doesn't load well, when I reboot everything works fine but rear camera isn't working. Maybe late I'll try with phone's camera. Now I'm using the new one bought some days ago.

same here!!!!! I'm using LOS13.1 on my d855 and i can't fix it... any idea?

What OS are you guys running? Is everyone experiencing the issue on Cm13?
Also try cleaning the camera connections really well.

I have same problem. Although i expirienced it first time on Lineage OS 14.1. Now 30B, but it still not working. I was listening to music through external speakers, and suddenly it stopped working. Music app was "playing" but i couldnt hear anything and when i exit the app my phone just stops working and starts being laggy as hell. Later that day i found out my camera is not working. I tried reattaching cam connector but it did not work...idk if i should order a new camera or it might be a software fix or something

same problem
happened to me after upgrading to 6.0 , downgraded back to 5 with no luck , even opened my phone and released and reconnected the 3 cables inside with no luck at all . don't know what to do

It's "good" to see other people with the same problem as me.
I replaced the camera and it still won't work.

I'm afraid that it might the problem with our motherboard...How can software block our camera even tho all of us fully reinstalled ROMs/Modems etc? It would be awesome if dev would see this and tell us what is the actual cause of this

If you reinstalled the entire OS using a TOT method, no files are left behind. This is more likely a hardware issue.
The Camera module is extremely close to the problematic hot chip on the G3 so it's not impossible something got messed up.

I have a d852 in Canada that doesn't get hot and I'm having this problem too. Going to order a new camera since I know this is a hardware issue. Hopefully fixed the issue. Not cool having no rear camera or flashlight

It's impossible Every G3 gets hot...you either are not heavy user or idk...but every G3 that i've held had the issue of overheating at some point...and indeed it can ruin everything...imagine 120C on your processor...that kills everything around it...idk if my processor got that hot as i've seen in some cases it did on internet, but it did go up to 90ish...and that is too damn hot

FIX ISSUE be Done
Hi all .
Problem method for repair
Issue is easy buy new rear camera D855 or this same conector D820/D821/Nexus5 is this same and all works fine I'm tested on my D855 International

In camea foult You cant turn on flashlight (software thinking camera all time working if camera is broke).
If u tru turn on flashlight he said (on broke camera) " Immpossible turn on flash light when camera work" !!!!!

[Q] Front Facing camera not working?

Hello
I've just received my Note 2 in the mail today, popped in the sim card and booted it up. Works fine and it's awesome.
When i checked out the camera, it launched fine and i was able to take perfect pictures using the rear camera, but when i switched to the front facing camera, it just came up with a warning saying "Kamera Mislykkedes" (Translated it means "Camera Failed") with 1 button saying "Okay" which would just close the camera app.
If i tried to relaunch it, it would stick to try and use the FFC and simply give the warning again and again.
If i go into Applications and clear all data from the Camera app, it would switch back to the rear camera and thus work again.
But i simply cannot get the FFC to work, i also tried downloading "Pudding Camera" off the market, and it does the same.
I found some other people having problems with older Samsung phones, and it can have something to do with some apps not releasing the camera app correctly after usage. But i haven't installed any apps that didn't come with the phone (except Pudding Camera, but it didn't work before that either).
Anyone got an idea? I really really really really don't want to have to send the phone back already because of a hardware issue, so that's why i'm here.

You can try if face unlook works.

Just a guess here but if a factory data reset doesn't fix it, it sounds like a hardware return sorry.

Just flash latest stock rom

What did you do to get it fixed? I have a similar problem
I have a galaxy note gt n 7000 (galaxy note I) and had this camera fail problem 4 months ago. I have even bought a front camera module from china but the product still didn´t get here. It takes more than a month for these stuff to come to my house in Brazil. Well, anyway, I had given up on trying to solve the problem (that´s why I bought the module) and I usually flash 3 or 4 roms a month (love to mess). So, then, I flashed the ROM super nexus on my phone and opened the camera normally, because the rear camera never had problems and guess what... when the camera opened I saw my face. Scared to death. kkkk. Now, it´s my fourth day using the rom and the front camera is working nice.
I don´t believe most of the users are having hardware issues. I think there´s something related to JB update because ppl started complaining about these camera errors after the update... but who knows. Hope u all have the same luck I had.
=)

[Q] Camcorder Freezes

Hi
Basically been having this problem for a while now and its starting to bug me. I rooted my phones ago now, and until recenlty the camcorder worked fine on all ROMS, however recently been facing a big problem with it. Every time I launch camcorder on any ROM my phone will freeze and have to take battery out and restart. I unrooted it and installed stock and it worked fine (so it can't be the SD card) re rooted again installed RSK and boom same problem. Does anyone have solutions to this?
Thanks in advance
If I remember correctly, the aroma installer gives you the option to change between two with a warning about one not recording. Also, have you tried another third party app to see if that works? You may also want to try taking the battery cover off and pressing (not too firmly) over the camera window and on the metal sheilding around it. It might have slightly disloged from the upper board but try the software first.
If you start noticing the notification LED, receiver (earspeaker) or camera flash not working as well, then it may need the upper board reconnecting to the main board and you should send it in for repair, but this is a pretty thin possibility, as I said, software first.

[Q] LG G3 Front Camera crash

I love my LG G3 but the front camera has been giving me trouble.
For the first week its great (except my wife keeps borrowing it for selfies haha). Then suddenly the front camera stops working. Trying to activate front camera in any app (I tried LG Camera, Google Camera, Hangouts with Vid call) results in that app locking up for about 10 seconds then crashing back home screen on a pretty usable phone. Do it once more and the whole phone becomes unusable - even long hold power off won;t work, requiring battery extraction to recover it.
I have tried removing data and cache from the camera app and that didn't help.
Tried a software data reset (via the menus), that didn't help.
Just for kicks I enabled ART in developer menu to see if that possibly helped, it didn't (side note: ART seems snappy)
So I am at a loss now, next step after this is hard reset, but I am not optimistic that will achieve anything the soft reset didn't.
Anyone else encountered similar issues?

It didn't. Result seems the same as the menu based reset. Not unexpectedly.
Hi there,
Just got my Lg G3 and all works great but after a while (few hours) the same problem accured...the camera crashed when i switched from rear to front and after that even rear wouldn't work.
I did factory reset...still same problem. Then i focused on my case...i realized that this problem appeared when i installed quick circle cover (it has no wireless charging on the back cover) soo i removed it and installed original. Camera works like a charm now!

Hi There,
Did you manage to resolve this issue with the front camera? I am having the same problem.
Thanks
Guys, do a hard reset..not a soft reset.
Anyways, its seems that there is a problem with the hardware itself since you mentioned that you've tried several camera apps and still force closing. Try bringing it to a service center..you might be able to get a replacement.

Camera frusturating problem

Hey guys,
I have a weired camera problem and I coudn't find anyway to fix it
The camera was working perfectly fine until one day It started being unresponsive sometimes and now I got to the point where it rarely responds!!!
When I open the camera sometimes it just shows black screen and I'm unable to do anything then after about 3 secs phone reboots and sometimes the camera app launches but the viewfinder is just black and sometimes it simply fc's!!!
I tried several camera apps (manul camera....) but in vain!
My first attempt to fix this was deleting data and cache for camera app! then I made a factory reset then I tried updating to android N DP4 and then I rolled back and in vain!!!
Once the camera srops working it will not work again until I reboot the phone and after I reboot it the camera will work for about 5 minutes to 1 hour then the problem starts showing!!!
Hope yo Guys can help me solve the issue I really like the phone and I don't wanna lose it!
Thx in advance!
Sounds like a hardware issue to me. I would send it in for warranty or repairs if possible.
Did you managed to get it fixed? I have the exact same issue. I think it first started happening after the latest security updates. I hope it's not hardware related, this phone just came back from lg repairs for faulty digitizer.
i got the same problem. i just try to install the final version of android 7.0 and hope the problem won't show again...
i'm anyway quite sure it's not a hardware problem, cause when the camera works it works great and shoots perfect photos and videos...i think it's the last security pack update which causes these problems, and maybe the solution will be the new security pack update, of september
I had the same issue, and I simply couldn't fix it by any means. It just started to happen after 3 months of use, and came out of nowhere.
I had to return it, luckily it was amazon......
Really weird.

Wifi and camera issue

Okay, so I'm having some issues with my G3.
1. Issue: Last night i noticed that my rear camera was not working. I was running Lineage OS 14.1. I couldn't rotate from my front camera to rear one, there was no option for that. So, this morning i installed stock MM 30B and i thought that it will work just fine, it could have been a minor software issue..well, it is not working. I also noticed that flashlight is not working either...AND my front facing camera is upside down What in the hell is wrong with that? I've searched for solution but on google but couldn't find it so i started installing apps that leads me to my second issue.
2. Issue: WIFI is SLOW. It took forever to download Facebook app from app store, even though the signal strength was maxed, and my phone was like half meter away from my router...My PC gets 55Mb/s and phone just over 5...
For the camera, i tried to unscrew my device to see if the ribbon cable is not attached properly, but i was unable to find a proper screwdriver...i managed to get 1 screw out, but it was pain in ass so i figured ill take him back instead of continue to take apart my device....
Any advice on this 2 issues? I'd appriciate it

Please reply there. Did the issue occur after you updated your cm13?
