I have LGG3 D855 MM stock rom, before I've had fulmics rom and that's when the problem started happening, figured a clean wipe and going back to stock rom would solve the issue but it didn't.
Flashlight won't work, tried other camera apps but it always fails.
Sometimes the camera starts working for a fraction of a second then it seizes to work and freezes the whole phone making it restart.
Figured it might be a hardware problem, but can a hardware problem with the camera freeze the phone? I don't really know, sorry.
Can anyone please help?
Update 1: Tried re-rooting the device and installing fulmics rom, still no luck, tried installing V10 camera app, nothing new.
Update 2: Front camera works sometimes but the image seems stretched, also it crashes after seconds and goes to black screen then freezes the whole phone sometimes making it restart by itself.
Tried the force stop and clearing cache and data trick in both camera and gallery and still no luck.
sounds like a hardware issue like a bad mainboard or connections loose or something, did the phone get wet? have u checked the camera connections with phone apart?

I've actually replaced the rear camera but am still having the same problem only without the phone restarting, maybe it's a problem with some wiring I guess? Any suggestions please?
Also, the phone never got wet.

i noticed a strange problem after i did the following:
1- Configure Face lock for the device and it's working normally
2- connect the device to PC.
3- after using the device normally for about 5 min restart it while connecting to the pc.
i'm not able to unlock it using the face lock anymore as the Front camera isn't working gives black screen even after restart!!! the back one as well!!!
i made data factory reset (twice) and the camera is back to normal.
has anybody been there or tried this before??
this happened to me 2 times after doing the same above steps.
can somebody help
in which mode do you connect your phone to the PC? If its harddrive, the issue might be that the camera cannot access the phone's memory and will not allow you to take picture.

of course not harddrive!
it's only in 'charge only' mode
also if it was like you said, after restart it should be back to normal but it doesn't
and its not about taking a photo, its about the camera itself doesn't work gives me black screen only.
This is the most similar thread I've found to my problem.
I noticed today that my camera isn't working anymore. When I'm starting any camera app the screen is black for a while(some ui elements are still visible). After ~10 sec the screen is covered in multicolored stripes. (cant link image since I'm a new user :/ )
The last time I remember it working was when using front facing camera in skype.
I have tried a couple of other apps, restarted and factory reset the phone with no results.

So many threads about proximity sensor problems, but none of them with the right answer...
I have this problem with my Sensor were everytime I reboot my phone or do a Factory reset using recovery,
EVERYTHING starts to work normal. It last for about 5 minutes when the screen no longer turns off when I get a call and get it close to my ears.
I dont know what it is i've tried different Roms and going back to ICS but the problem keeps showing after some time. There must be some Gnex users with the same problem and yet there isnt a solution... perhaps is a hardware problem? maybe not because each time yo reboot or factory reset... the problem goes away. Any help will be appreciated.
Hi!
I brought my Xperia Play phone USED two years ago and I've never had any problems with it.
However, recently, the phone has started to freeze itself in "screensaver" mode (Where the screen goes black after 15 seconds and locks the phone), but the screen won't light up no matter which button I press. I've had to restart the phone every time this happens.
It's been behaving strange at start up as well, as it sometimes take 20 minutes just for it to turn on, while on other occasions, it won't turn on at all!
Is this problem caused by the battery, or is it the hardware?
Is it with stock firmware?

Yes.
I've never modded it or installed custom firmware/apps.
Have you tried factory resetting it?

Yes, but it didn't fix it. The problem still occurs.
tldr: Black screen, no display, everything works "under" (I can answer the phone etc). Not a flex cable problem because occurs randomly, regardless of the slider being open or closed. The problem also occurs during boot up, so rather not a software problem.
I think I have something similiar. Everything was fine until a few days ago the screen didn't want to unlock..or at least I thought it was that.
Basically the phone sometimes works OK but sometimes if I turn off (lock) the screen, it won't go back. To be precise, the phone works and if someone calls me I can pick it up moving the finger where the slider should be, it's just the display doesn't turn on. Same goes for booting, bootloader logo etc, so IMO it's not a software problem.
Strange thing is that it just randomly pops back, sometimes when I move the gamepad slider, sometimes when I put in a jack cable or if I hard reset the phone (remove battery). I've had problems with the flex cable in the past and this time I know that it's not it (no difference if I open/close the slider).
My guess would be some power supply or LCD driver IC issues, because the screen stops working almost everytime if I put the phone into the dock. Moreover, if the screen doesn't work, the orange charging LED is not working (green and blue are OK). The moment the screen starts working, the orange charging LED starts working too.
it's very strange but I'm used to electronics doing strange stuff. Just wondering if I should give a try disassembling the phone and trying to fix it or just buy a new one or something?
I might add that I have bought a new battery ~3 months ago, but it's been working fine to this point. I have tried if the same problem occurs with the old/original battery and it's the same.
well, any ideas?
edit: This video shows something very similiar (except the backlight): https://www.youtube.com/watch?v=m4p0-kv1cxA
Same problem. And I guess this guy has it too.

Hi, I don't know if this has been mentioned anywhere and yes i know the bootloop issue is a big problem but i wondered if anyone else has been semi-successful like me. First off the other day my phone rebooted and ended up in a bootloop except the screen never goes completely blank it just dims and comes back on. I did a hard reset and it starts working again for a few days. Then when i connect to wifi it will reboot all of a sudden and be fine until it reboots again and i have to hard reset for another few days. sometimes when looping it will get to the updating apps screen then when it finishes it loops again.
Is this the standard bootloop or does it seem like something different?
Sorry if this is just another repeat of an old issue it just seems to be slightly different from what i have read about the bootloop caused by the known hardware issue. Also the first 3 digits of the serial are 507 if this helps.

Maybe yours is jut preparing for proper bootloop maybe the pins on the bigger qualcomm chip still connect to the motherboard from time to time so you manage to get it booting. Though I wouldn't call it a working device so I would suggest you to start working with LG to have it fixed.

flash stock firmware and then try it for weeks if it happens then hardware is damaged..

Dont play around with it too much it might get permanently bricked ur best option now is to flash a lollipop kdz root it then apply the disable core method to working it again ofcourse the phone will be slow ...or u could just send it to lg for replacement or repair...check youtube for disable core method for g4
I have just plugged it into Lg bridge and run the update error recovery. It hasn't rebooted when connecting to wifi yet but if it does I'm just going to phone LG to sort out a repair and buy a temp phone to use while that happens. I just don't want to do anything that could affect warranty although usually, the warranty would be out the window on day 1 with me
It just seems weird that every time I have seen it reboot it was when it connected to wifi.
Hey guys,
trying to fix this LG G4 which has problems with sound. There is no sound at all...
Tried to factory reset but that didnt help, even re-installed stock rom with LG Bridge in Download mode using the "software update error" method.
The bootloader is unlocked if that matters..
Important info: After factory reset the volume is at ~50% .. i can turn it up and down (but no sound) but when you turn off the volume completeley and turn it back up it starts to hang and system crashes (force close "system" and the ui restarts).
Even over the headphones there is no sound.
Any ideas? How can i return it to 100% stock (relock bootloader and flash EVERYTHING including the bootloader n ****?)
nobody have an idea? I dont think its the hardware - even headphones give no sound at all...
MAYBE if its hardware then it must be the sound chip itself.. but the phone looks pristine

If the issue persists after a factory reset and reflashing the stock ROM, it can't be anything other than hardware, sorry.

It actually is/was hardware related:
After flashing it for the 100th time without a difference (no sound, logcat reporting /proc/asound is missing) I figured it has to be the audio chip. So I teared it up again (luckily i didnt put the screws back in yet) I used my heating gun to heat up the audio chip and put everything together again. AND... tadaa there was sound!
It went away after the first boot though - so i gave it some extra heat. =)
now it seems stable so far...
aaand its gone ... again
so after heating it up some more audio is back for good - lets hope this lasts.
For those who are also affected:
The audio chip is the small black chip in the top right corner on the upper side of board. It seems that there is a small battery close to it - at least it looks like one. Be careful not to heat up the battery too much.
