Had the same problem.
Great temporary fix: right after you unlock the screen hit the volume button once or twice. Not a permanent fix but it works for the time being.
It usually blacks back out because something is wrong with the proximity sensor next to the front camera. Either it's covered partially, dirty, a screen protector is peeling off over it, etc. I've read that some people have problems with the screen not coming back on during calls because the proximity sensor is messed up. Some said to use a high powered suction vacuum and put it up against the screen to get debris out of the cracks or simply try wiping it clean if there's something on it. Hopefully it works!

Oh god, I just permanently fixed my proximity sensor \o/

So I had the issue where the proximity sensor would detect something near it, making it hard to wake up the phone (screen getting dark after half a second, as the phone thinks it's still in my pocket) or keeping the screen dark after a call.
An app displaying the proximity sensor output was showing the sensor always reporting 0cm when it's not working, and 5cm when it's fine.
If your get "no data" in a test app, then sorry you have another issue. Probably a dead sensor. If you do get the sensor always returning an obstacle at 0cm, keep reading!


I also noticed that pressing on the screen around the sensor kind of made it work. So I thought for a while my screen was slightly off, maybe slightly unglued.


But it's the opposite: it's actually the sensor that was moving a bit, thus getting too far from the screen surface - and detecting the screen as the obstacle. Just by a ridiculously small amount.

Now THE FIX:
  • I switched off the phone, and removed the SIM and the rear door,
  • I removed the 7 screws holding the top plastic plate and buttons
  • On the rear of that plastic plate with the buttons, there's a small soft pad that pushes on the sensor to hold it against the screen: that's your target! That pad is just a tad too thin.
  • I've put a very small piece of adhesive tape (I used a slightly thick double-face white tape, maybe a tenth of a millimeter) on that pad,
  • Then I put everything back together and... the sensor now works! All the time! And the knock-on too of course.

I can't post a picture of the pad below the button assembly. But if you look for "OEM Part - AT&T LG D800 G2 (WHITE) Rear Back Housing + Buttons + Camera Lens" on ebay, and look at the 2nd picture, the pad is the fully black rectangle on the top left, on the right of the empty black rectangle and below the half-circle small opening (probably for the light sensor).

Plug proximity sensor issue
i had the same issue for my lg g2 . when i searched the internet for solution , all i got was to install proximity sensor disablers , rooting apps to disable them . i have solved the issue interms of hardware . the solution goes :

1 . go watch a youtube video of teardown of lg g2
2. in the video there will be showing a plug that connects the sensor to the circuit board.
3 . pick up a screw driver , open the casing of ur phone
4. unplug the connection between the board and the sensor
5. put everything right back
6 PROBLEMO SOLVED BAYBE

thank me

Just in case someone searched and finds this thread - the easiest way to disable the proximity sensor on any rom/kernel is to go through Xposed and this module: http://repo.xposed.info/module/com.m...er.disableprox
Works on 4.4, 5.0.2, Cloudy's rom, Dorimanx's kernel...

After almost a week trying to solve this, your answer hit right on the spot! I found it funny how the roms not based on stock LG's are not affected by this issue, but all of the LG's ones (I've tried 4 LG's stock roms and CloudyG2) so I've always assume this was a SW issue (and probably can be addressed via SW) so when I get to your answer saying that could be fix tearing the phone apart I was reluctant to do so, but as I've told you guys I was desperate. On a sidenote, the Stock JB ROM is not affected by this, but it is death slow for this times.

BTW, I've wanted to have a ROM that had the LG's camera app (any version) since the ones that came on the CM ROMs wasn't really good enough for my taste, so now I'm rocking the CloudyG2 3.2 ROM with any issues so far.

Your fix gave my phone some solid 6 more moths of life! (at least!) THANK YOU!
