Camera stopped working ("cannot connect to camera")

Hello everyone,
I bought a few weeks ago from amazon this phone: LG G4 H815 5.5-Inch Factory Unlocked Smartphone (Metallic Gold) - International Stock (No Warranty)
I know it says no warranty but I have to try. The thing is that yesterday, out of nowhere, the camera stopped working. Whenever I open the app it shows the buttons but the screen remains black. After a couple of minutes it shows the message "Cannot connect to camera".
I tried the following without success:
-Stopping the app and clearing the cache and data
-Rebooting in safe mode
-Disabling Nuplayer in the developer options
-Factory reset
Please help.
Thank you!!

mines h811 too.. well its not the infamos MB hardware failure.. as that will not boot phone... i suggest to get it repair. where did you get it..? as i see you from another country.. did you flash refurbished i=option??
I got the same issue and had to take it to service center to get it repaired. Since mine was under warranty the repair was done for free. I was told they replaced the board.

lg g3 no service detected !

Hi everyone
i have an lg g3 d855 EU working just fine for 1 year and a half ,
And lately when i upgrade to Marshmallow and then i stated flashing a different custom roms and they all work fine!
But a week ago I got a strange problem! A sudden msg appear for few second and then phone keep rebooting:
“Mobile network will be unavailable until you restart with a valid sim card”
I’ve done a lot of research and tried them all but still the same probe:
-put a piece of paper on the top of the sim cad
-replace the sim card
- Factory reset
-flashed android 5 the original kdz file got from official lg firmware using my IMEI
-....
So I decided to get it to a technician!
-so he replaced the sim card reader with a new one! After that the phone went just fine for 4 days and then the problem come back, so I get it back to him, so he replaced the reader with second new one and he told me that the reader is not the problem and is 100% working so when I put the sim card and reboot it ask me for "pin code" but when I after put the pin code, the phone keep searching for signal for few second than it stay no service at all.
the technician sad that there is some file in lg g3 responsible for the service detection and stuff like that only be obtained from another working lg g3 and only solution is that he can get those fil from a working lg g3 and put it into my phone and he told me it will be working again for sure !
So please guys help me I’m stuck !! Is there anyone know something about these files or their names?? And if he can provide me them I’ll be so grateful. :good:
Haven't seen this problem before. A file issue? Perhaps do another complete factory reset then do a complete wipe flash of the global rom, using the LG flash tool. Get the rom here http://forum.xda-developers.com/lg-g3/general/lg-g3-android-marshmallow-discussions-t3216143
I use that rom so there shouldn't be any issues. Hope this helps

No signal or emergency calls only After upgrading or flashing ROM LG G4

Hi all,
I bought an LG G4 from Aliexpress Two months Ago, I think it's an LG G4 H815T (hong kong version) It was working perfectly until I decided to upgrade the firmware (to android 6) with LG bridge and since I made this action, I could not get signal on the phone (most of the time) and some times I get full bar signal but only emergency calls are allowed.
I tried also to downgrade to android 5 again but with no succes (I tried all possible roms and for all variants)
the strange thing is that the phone was working quite good so I'm sure that it's not a hardware problem.
Can any one please tell How can I fix that?
thanks in advance
Does any one faced the same issue before ?
Same here
I don't know if you are talking about the same issue but this occurred for me randomly. Before restart used to fix it but now nothing helps, also when I search for carrier it says your sim card can't connect to any or something like this although I have full signal bar :|
Same issue with mine
Try to restart the phone when it's connected to a power-supply or a running computer, it works for me
Same issue with
My problem is the same please help me?
thanks...
My LG G4 H818P also have the same problem.
Hope there is a solution for this.

LG G3 VS985 No Sim Card Detected.

Hey guys. I have a Verizon LG G3 running Resurrection Remix Nougat 7.1.1_r9 Nightly build. Before I was running this ROM I was running CM12 and then one day my phone said no sim card detected. I went back to stock and updated and I still had the same issue. I am now on Resurrection and my phone was fixed for a little bit. Then it stopped working. Then it worked. Now it has stopped again and only came on once yesterday randomly when my wifi wouldn't connect (I restarted my phone). I have tried just about everything I could. I got a new sim card from Verizon, I cleaned the sim tray and did not notice any damage to the tray (all pins are in contact). I'm at a brick wall right now and could use some help. Thanks!
I have the same issue with my LG g3 vs985 . With the same rom also . When I press on cellular networks in settings, it says that "com.android.phone has stopped " . I've cleared cache and data of com.android.phone app and it still the same problem. I need help . Thanks .

It would be better to flash this custom rom ; it's working perfectly ; just wait a moment until it recognise the sim card ; this Cr droid rom is based on android 7.1 and it comes also with night light . Now , the problem is solved for me !! :good:
go to the " androidfilehost " website and search for this " crDroidAndroid-7.1-20161029-vs985 " then download the zip file
enjoy !!
I have a weird issue with my vs985 it takes too much time to boot up.. some time it boots and some time it does not boot.. i had to pull out battery fot 20 or more minutes .. i dony know either its software are hardware issue . may be some one experienced this issue .. is there anyone who know about this issue .. i need help...

You have to install any ROM, but before you have to Unlock the Bootloader
