Hello, I have a problem with my LG G2 VS980 by verizon.
There are two problems depending on preloaded rom
1 The display shuts down immediately when call to someone. (after the conversation has will not turn on)
or
2 When someone call to me, after a conversation I can not unlock the screen (either the knock on, or by power button - appears on the screen and immediately turns off).
I've tested all the roms that are available. The one who runs without problem with the display there is a rom by HeatshiverSX - 4.3.1. The problem is that this rom has problem with the rotation of the screen.
Are you able to tell what's going on? Could someone help / advise? Thanks!
Anyone ?

Did you manage to solve it by now?
If not, it seems that @Bam9 manged to solve it by a firmware update as he reported here.
It seems that there are two similar issues in LG G2 which are both caused by the proximity sensor which causes screen and touch problems during conversations:
The screen stays on and the touch buttons in the dialer (speaker, add call, mute, etc...) aren't responsive.
(This issue was already reported by @athorax here)
The screen turn off and goes blank while in conversation.
(This issue was already reported by @madafis here)
In both of these situations the only quick way to end a call is to pull down the status and notifications bar and hang up from there.
Thanks to @Bam9 and @EtherBoo , who suggested to clear the proximity sensor from the outside and squeeze the top left corner of the phone, I tried to clean it and put some stress on it - and it worked!
I have a glass screen protector (which don't block the proximity sensor), and I am rooted and using CyanogenMod 11 ROM.
I used ioroot to root and AutoRec, which comes with TWRP 2.7.0.0, to install CyanogenMod ROM.
However, going back to stock ROM (in my case, LG G2 D802, it's D80220C) won't help since the issue still exists.
What I'm sure is that it was pretty much okay in the beginning, and the situation became worse and worse - occurring randomly, until it arrived to a situation in which I can't use the phone properly during conversation.
Now that I discovered that I can put some stress on the proximity sensor it seems that I have a hardware rather than a software issue.
So my LG G2 D802 is using a stock Lollipop (5.0.2) ROM from Singapore that I flashed recently, lately my phone sometimes get ghost touches and sometimes the screen stops functioning. So my question is, can it be a software problem rather than hardware? When the screen is unusable, I can swipe to unlock like normal but when unlocked whatever I press doesn't do anything. The vibrate on touch is there but no action.
I am having the same issue. Have you got the solution yet?
Hi there,
i have here an old LG G2 D802 with Custom Rom /BLiss ROM 6.4 on it. The Screen was cracked, so i changed it with a new Front Body Set incl. Display and Digitizer, everything works fine, but when i try to call someone the screen just gets black and doesn't react until the other side from the phone call hangs up. I think it has something to do with the near sensor?! who can help? also i cannot enter the LG Secret Menu with the code "3845#+802" then the screen gets also black and i can only start it new via pressin the ON Button
how can help?
must chek position of the sensor under the glass i have this issue ,but after disassembly the phone and correcting its start work as it should

i recently replaced the lcd and also have the same issue. It detected that my screen is covered so i can't hang on a call because the screen wont turn on.
but suddenly it works when i cleanup the screen with a damp cloth. but sometimes it doesnt work.
I know this thread is super old, but before I start a new one on exactly this - I had to disassemble my phone to replace the audio jack, and since then, my proximity sensor won't work at all. I double checked the flex cable and plug, tested the sensor outside the phone, still nothing. It ONLY works if I put sth white or metal-like exactly 2 mm away from the screen, no nearer, no further. Its super strange and annoying. Was anybody able to solve this?
Edit: LED and ambient light sensor (which is exactly the same sensor) are working! And before the sensor stopped working I did not even touch it at all!
After screen replacement KnockOn (double tap) does not turn on the screen. Screen replaced by specialist. I search this forum and find Hidden Menu. 3845#*722# Proximity sensor seems work. I tried to update touchscreen firmware, but it freezes phone until i take battery away. So phone is working right now, but KnockOn does not turn on screen. What else i can do and how i can update touchscreen firmare?

Are you sure the screen is 100% an LG OEM screen?
