Hello,
I just repaired a G3 screen and found that now, the G3 only works after the first time you unlock it, when it boots up. It works perfect, but when I press the power button to lock it, then when I press it again, the digitizer doesn't work. No matter if it there's the pattern lock, or anything. Could it be that te proximity sensor is damaged? How can I deactivate it in order to try it?
Thank you

I have tried an app that tests the proximity sensor and it works perfect. I don't know what is happening..
And it works now, trying, after closing and opening the smart cover... But I have to do it everytime I need to use the digitizer... Is strange
Thank you
Does anyone know what happens? Maybe the clue is in settings, but I haven't found anything at this moment.
Any clue?
Not working after hard reset
I've hard reseted the phone, and I have still to close the cover and open it to make the digitizer work. Do you know if installing another ROM will fix the problem?
exact same problem here
Have you found the solution yet?
Had the same problem with my G3, had to send it to warranty repair, cost me 130 euros since I had it fixed with non-official parts, it had to do with the proximity sensor being behind a certain type of glass that didn't allow it to work properly.
To summarize it into two solutions now, either I buy the lg g4 smart cover to bypass the digitizer problem or to send it to warranty and install the original glass back. Will it be the same if I replace the non original glass with original glass from lg myself?
If u could gwt away with using a g4 smart cover on a g3 then id choose that route dude. Download the app offerup and see if anybody local has one. People sell tons of phone cases and accesories u might find one cheap i use this app its where i bought my g3 from for 100 bucks lol

Is it lg or samsung that has this feature where when u use a smart cover only that part of the screen lights up n the other pixels are off to save battery? I read on it a few years back
I think I have solved the problem on my g4. I open back back my phone motherboard and reconnect and test the digitizer for a few times. It seems that my Mainboard is not pushed enough against the digitizer. Right now if I press the back of my phone a bit hard. The problem will appear again. And I need to press the back again for a few times to solve this.
my old boss has a business fixing phones. I use to help em with iphones. Well i had broke my lg g2 n asked em to fix it n he says he dont do Lg g2 g3 or g4 he said he lost so much money doing them because half the time after fixing it the screen wouldnt even power on. He said if it did it wouldnt last longer than the 1 year warranty he offers. Idk why that is because he fixes just about any other phone but LG he didnt mess with.
Verizon VS-986 here.
A couple of days ago, I went into the Camera app to take a picture and it was "stuck" on the selfie camera, and the icon to switch to the main camera was gone. I went back to the home screen and back into Camera, and fiddled with the Modes, and it finally came back. I clicked on it, and the app showed an image for a couple seconds, then froze up. I did a lot of back and forth with it, and sometimes it would show an image for a second and freeze; sometimes it went totally black and froze the app; eventually, after power cycling a few times, it was stuck on the front-facing camera for good, with no icon to swap to the back camera. Basically, at this point, the app had recognized that there WAS NO back camera and didn't even bother presenting the option anymore.
This had all the hallmarks of a hardware problem. Glitchy, intermittent outages, then the hardware simply not recognized anymore. Still, I cleared out caches and searched online and found this article: How to Fix Camera Failed Problem on LG G4 (recomhub.com/blog/how-to-fix-camera-failed-problem-on-lg-g4/), none of which did anything to help. (I'm not rooted/unlocked so I couldn't clear the cache partition like they recommended, though it clearly wouldn't have helped anyway.)
Couple other things that may or may not be relevant: it was VERY hot out (80+ degrees) when then problem started and the phone was hot as a result of it. But it kept happening after cool down.
A crazy other thing that happened was, that evening, after rebooting one last time just to be sure, half the screen turned into rainbow noise during the Verizon logo and stayed that way for several seconds, even into the lock screen. That pushed me over the edge.
I went to a Verizon store and they kindly swapped it out for me. But that was weird and I wanted to put it on the record. Also curious whether anyone else had this problem.
Not that problem, but check out this other thread I started regarding the camera causing the phone to overheat: http://forum.xda-developers.com/showthread.php?t=3142806

I've had the rainbow noise on the right half of the screen show up on boot at the Verizon screen as well. It stayed that way until the lock screen and that's when I powered the phone off, pulled the battery and let the sit for a few minutes. Haven't had the problem in the weeks since I've had the phone though.
The exact thing happened to me. My rear camera will not work at all. And the flashlight also will not work. Tried rebooting, factory resetting it, clearing cache, and took out my battery and still nothing.
I had a Verizon G4 that the rear camera stopped working on. I believe it was caused by a drop. I posted on here about it. For mine it just wouldn't focus anymore. Replacement was very easy, you only need a small Philips head screwdriver, and your fingernail, or plastic tool to remove the connector and pry the camera out which is held in by adhesive.
Replacement OEM part out of a Sprint G4 was under $14 USD on eBay.

Hello,
I have the exact same issue. Do you have a solution ? I dont want to rma anymore, screen coating than bootloop than this, this phone is a true disaster.
Only other thing any one could try is a tot lgup restore if that dont work either more than likely its a hardware failure. I had issues on my g2 with a could not connect to camera from the factory. Found out my stock rom was corrupted from lg toted and worked like new. Did it again a few moths later. Toted avain worked like new. I asume something in the camera files corrupted. Just throwin in my 2 cents.
Hello, thanks for the answer.
I fixed the issue by myself few minutes ago, i simply disconnected than reconnected the rear camera plug to the motherboard.

UHi. I've been on this site for years but have never posted anything. I've got a problem with my 'new' LG G3 D855. I just got it off eBay today.....and I already broke it. I'll start from the beginning.
First, I'm using a Tracfone BYOP sim (AT&T). Back in August I bought an LG G3 D850 (AT&T model) with a cracked screen for $25. It wasn't until November that I replaced the screen for it. Swapped sims, everything worked right away. Headphone jack was broken and the power/volume buttons were slow to respond. Then, I realized it had a bunch of AT&T bloatware, so I tried several different ROMS. The one I liked the best was Fulmics 4.1. (Didn't like any of the later versions with the new layout). Replaced the headphone jack. Worked. Then I replaced the power/volume button ribbon cable. When I did this, the rear camera stopped working, as did the flashlight. I tried replacing the rear camera and that did not help. I got it working once, but only for a couple minutes. I assumed the board was defective and I wanted the FM radio anyway (which I didn't know the D850 variant didn't have when I bought it). So I threw away the board.
Phone two. Instead of replacing the board, I just decided to get another phone for $30 with a cracked screen (also power button was not functioning right). This time it was an LS990 Sprint variant . FM Radio worked, but since it was not a GSM phone, no service. Tried PrimeGSM ROM and got service. Lost the FM radio though with the ROM flash. Eventually gave up on that and now I'm at phone #3.
And now I'm at the D855. Did not have FM Radio with stock MM. Replaced it with Fulmics 4.1. Has service, data, and working FM radio. And this phone was fully functional, looks barely used.....except for one issue. The power/volume buttons don't work too well. Figuring this would happen I ordered the buttons the same day I ordered the phone. I just swapped out the power/volume buttons about 10 minutes ago. Now the rear camera and flashlight don't work. Camera/flashlight was working before I did this. I didn't even touch the camera or the camera connector on this phone. Is there any way to fix this?
Update: The fix was to replace the back housing with a new one. Got a new one for <$10 on ebay. Everything on the phone works like new now. Hope this can help someone else if they ever come across the same issue.
Hello everyone, i have searched everywhere and i couldnt find anything for LG G4 with this problem, there are shuck problems with different models.
Days ago i replaced my LG G4 screen with a new one and the camera had the focusing problem at first. after i reseated the flex cable of it everything was ok forone hour.
After a restart of the phone the rear camera option has desappeared, only front camera is working now.
I have read people had the same problem with LG G3, Nexus and even other brands as Alcatel Motorola and so on.
Does anyone had the same problem, and if can confirm that is software or hardware problem.
