Lg Vs980 Proximity Sensor and Dropped calls - G2 Q&A, Help & Troubleshooting

Hey guys, just wanted to start by saying hi, I've used XDA for trouble shooting and reference for a year or so since I've gotten into custom ROMs and rooting etc. I'd still consider myself quite a novice so I apologize in advance if I don't supply appropriate information.
Before getting my vs980 I had a ls980 with the exact same issue (only I was running cm12 nightly). When going into a call the screen blacks out, so obviously you can't use speaker mode or if your in a phone tree you can't enter numbered extensions etc. My research suggested that the proximity sensor was at fault, and with the use of several apps found the proximity sensor not working. I tried to turn off the sensor with exposed sensor disable app and it wouldn't work. The only difference from the ls980 to the vs980 is that now my calls drop randomly without notice. I am now running cm13 nighty and I'm not completely sure the black out issue and the dropped calls are connected. Has anyone found a work around for the proximity sensor black out? I would love if their was an option for this. Please let me know if an further info can help. I also experience random restarts with cm13, but one problem at a time.

Screen going off during call or when call is over on G2 VS980

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.

[Q] In-Call dialer unresponsive...

So I have seen this issue on multiple forums, across multiple roms/devices, but can't seem to find any solution.
I have a LG G2 on VZW (VS980) currently running AOKP 5/24 nightly (but I have had this issue for months now).
When I make a call, the in-call dialer interface is completely unresponsive. I can't hang up, open the dial pad, speaker phone, mute, etc... the only way I can hang up is to hit the back navigation button and then pull down the notification and hang up that way. I am running PA micro gapps, but I have had the same problem with other gapps as well.
Does anyone else have this problem or has found a solution?
Bump. Really looking for any ideas on how to fix this.
I'm in the same boat here. Would really appreciate if someone could provide a fix.

I fixed my issues by flashing the "Google Dialer" in this thread
Same issue - can't use the touch keys in the dialer while in conversation in LG G2

Thanks a lot for posting your workaround.
I have exactly the same issue - I can't use the touch keys in the dialer while in conversation in LG G2 D802 (Intl).
However, the Google Dialer is an old app that got replaced by Hangouts Dialer.
Did you switch to Hangouts Dialer, or you stayed on KitKat 4.4.2 with the old Google Dialer from the post you provided?
By the way, I posted issue CYAN-6090 in the CyanogenMod JIRA in order to try and get resolution to this issue.
Are there any other users with this issue?
Did you solve it somehow?
note: sorry for not posting links. I have that annoying new user limitation...

[Q] What mod allows you to disable the in-call proximity sensor?

Hi everyone,
Long story short, I got a used Nexus 4 off someone, everything works perfectly except the proximity sensor. During a call the screen blacks out and doesn't come back unless I hard reset the phone to hang up. I figured out it was a problem with the proximity sensor. Upon reading these forums and many other articles on Google about taking off the screen protector (which I don't have) and swapping the rubber "sensor" holder holes, I decided to open the phone up and take a look.
It appears that my phone is missing the rubber piece to hold the proximity and light sensors in place, making the sensor unusable and causing many issues with making calls. I've tried playing around with it using other peoples' suggestions and nothing has worked. I've decided to just find a way to disable the proximity sensor instead during a call, as I'll be quite satisfied with just a simple software fix.
Right now I am using Proximity Screen OFF to keep the screen on, but it drains my battery pretty hard. I was thinking to just flash my phone with a mod that allows me to turn the proximity sensor off during a call.
Any suggestions as to which mod contains this feature?
Thank you.

[solved] Screen Blacked out after making a call?

Hello,
I have the i9505 and i have flashed it with [ROM]【4.4.4】Google Play Edition 07-17-2014 - Pure Nexus Edition build now available by @Danvdh and i absolutely love this ROM and works like a charm but there is one thing i am having issue with and i cannot say its a bug as looked over his thread but no one has mention it. i can comment or post in the developer thread due to the number of posts i have, however i come here to ask for help.
When I make a phone call, my screen goes completely black and when i try wake the screen up, it would take multiple times and sometimes i have to take the battery out. The call somehow runs in the background, so if i managed to wake the phone, i have to pull the notification down fast to hang up and this is pain in the neck.
I suspected it could be the proximity sensor in my phone, i have no cover or screen protector, i cleaned the screen and still the same. so i ran few tests to check the sensor. phone detects the sensor but it doesn't do anything.
Thank you in advance
after many research, i have found the issue and its fixed.

you will need to reset the proximity sensor depending on the values. i can say all working now

Disabling the proximity sensor

Hi guys,
Was wondering if it was possible to disable my proximity sensor? The reason I ask is because since I dropped my phone a couple of weeks ago, it does weird things.
When I try to call someone the proximity sensor registers 8cm (give or take as this is an example) but when I put my face to the phone, it latches on 0cm and never resets to another value. Thus keeping the screen blank.
Same outcome happens when someone calls me.
I'm currently using Lineage OS 14.1 (Android 7.1.1) on the Samsung S5 (SM-G900F klte). I'd rather disable the sensor if it means regaining control of the phone during calls.
Thanks guys!
Bump
