Not always but at random times when I receive a text or a call the screen would stay black and wouldn't allow me to receive the call etc. The rings would keep going but the screen stays black. I am using Cyanogenmod latest nightly and AGNi kernel. Is there any way to fix this?
But if I give some time, the screen is back up. Happens during and after calls too. It's not a regular thing but it would happen randomly once a day or so.
It sounds as though the screen sensor isn't detecting the call. I know this is a common issue in a few lollipop based roms. One reason I personally haven't stayed on an LP rom. I believe that you can change certain settings in the build.prop file but as to what they are exactly I'm not familiar. You would need to search a few sites to confirm.

I am a new android owner. When I make a phone call the proximity sensor turns the screen off... great, no accidental screen pressing. However, when I finish the phone call or take the phone away from my ear... I get the lock screen. Why? Why doesn't the screen just go back on to whatever screen was on before the phone call... like the dial pad.
I find this annoying. To hang up a phone call, I have to unlock the screen first.
What phone are you using? Software version etc and are you rooted? This doesn't happen to me so it's not a general android issue.

I have the Moto Droid X. Running CyanogenMod 7.1. Also using exDialer as a dialer replacement.
Does it happen with the stock dialer? If not that's your answer

Yep it happened with the stock dialer on ICS and it is happening with JB as well. I am really surprised it doesn't bother more people. What is most annoying is that, I initiated a new call and put my phone to my ear to only that the call did not even establish (e.g., due to network iss ue) and when I want to place the call again, it is already locked. It is definitely due to the proximity sensor, as the same thing doesn't happen if i never put the phone to my ear and just keep watching the screen to confirm that the call did get established (and started ringing).

If you are rooted, disable your Proximity Sensor in a call. To do so, add following line to /system/build.prop file:
Code:
gsm.proximity.enable=false
.
Plus, make sure to make screen timeout period long. You can use Widgetsoid app (or, other toggle apps) to make it infinite.

I have display timeout set to 2 minutes, so that can't be the problem, as the whole experience when the call is not connected only takes 10 or 15 seconds to complete. However I have security setting to lock the screen in 5 seconds after the display goes to sleep. Perhaps that is somehow related, so I just increased it to 30 seconds, I will see if the problem goes away.
I've searched with several different search strings and haven't found an answer to this question, so here goes;
When I place a call and bring the phone to my ear the screen turns off (dims?). At the end of the call after I bring the phone away from my ear, it takes several seconds for the screen to turn back on, sometimes it doesn't turn back on unless I press the power button.
First, is this the normal behavior for the phone app on the I777?
Second, is there a setting somewhere to change the delay for the "screen on after a call" (I know there is a setting in settings-display for screen time-out).
I hate to make the comparison, but on my iPhone (No flaming please, I'm reformed) the screen turned off and on very quickly and I just wonder what I need to do to get that kind of response on the SG2, during the phone call.
BTW, I'm running UnNamed 2.2.1 (Gingerbread 2.3x) with Entropy's kernel.
Thanks for any help.
Clean your screen.
You using a case? Maybe it's partially blocking the proximity sensor.

Ironically I had the same experience in UnNamed to I assumed it was just the nature of GB. It may very well have been as I don't have that issue with ICS based ROMS. And I like the dialer better to boot.

OK,
I'm in the throes of upgrading to an ICS ROM, so maybe I'll just go ahead and see if that fixes the problem.
Thanks for the answers
I think its a sensor issue having to due with how long it waits to scan again after light levels are changed. No idea what stock settings are but I can say I don't have a problem with it on AOKP.
Hi guys.I have a problem with my LG G2 D802.When I answer a call or make a call,the screen goes blank and the touch doesn't work anymore.I can't do anything else on the phone.The conversation is normal and anything else seems to be ok.Please help! Thank you.
If I answer a call,the screen goes blank,I can speak normally:After the call even the other person finishes the conversation,I still can't do anything on the phone,because the screen stays blank.If I have another call this will awake the screen and it will work normally,I mean,I can take the call,answer and speak on the phone but with the screen blank again. and so on.To have the phone back to normal,I have to reboot it by switching the phone off and on again. Very strange.This happened after I unlocked the phone ,probably because I left the SIM card in ?!!! Any possible advice/solution? I tried soft and hard/factory reset with no results.

I actually had this same issue. my g2 is rooted, but running the stock rom. it has a screen protector but nothing else that would impede the sensors.
I found that this issue never took place in well lit areas. but if at night sitting i a poorly lit room I would go to swipe the scree it would unlock for a second or two and then lock back up. in talking with a friend. I found that the g2 has in set so in the proximity of a pocket or something dark the screen dims back so as to not allow you to mistakenly hit ay button ( i.e. butt dial) i figured my proximity sensor near the ear piece was dirty and causing much less light then there actually was. at the time there wast a firmware update ( which I have now gotten) and was desperately seeking help.
I finally got the firmware update VS98012B and it seems to have solved the issue I ( and you) was having. I would see what version you are running now and then update to the aforementioned and see if that solves your problem.
PM me and let me know what road you decide to travel and if for some reason it doesn't help you we shall figure it out.
Blank Screen
I am having sort of the same issue. But mine is wether in a well lit room or dark room it doesn't matter.
I noticed that it usually happens when i receive a call, after the conversation when i hang up it does not go back to the home screen. all i get is a blank screen. the only way i can get it to generate the home screen again is by pulling down the status bar and going into the general settings and clicking home button again.
during this blank screen i can still see the status bar, and when i bring down the status bar i can see the nav buttons but they are unresponsive.
I also noticed this takes place sometimes after closing an app (noticed on netflix)
I am rooted on stock rom and TWRP recovery. Phone Model [LS-980 Sprint]
I immediately rooted so dont know if issue was there before root.
SOMEONE PLEASE HELP.

I decided to open the phone and check the proximity sensor.I unplugged the proximity sensor ribbon and guess what:IT WORKS.without the functions of the proximity sensor and LED.But at least,I have the keypad and the screen on during a conversation.I have even the knock-knock function.Probably,I will use it like that until a kit-kat update will be available.Thanks for your answer.
VS980 Black Screen
I have a customer phone that I replaced the LCD and Digitizer on. The new screen works fine but...now when a SIM Card is in the phone and I dial out a thin horizontal line appears in the middle of the screen and then the screen goes black.
If I remove the SIM card and place a call, the phone gives me the standard "Emergency Calls Only" and goes back to the dial pad.
The SIM Card is not activated but it is recognized by the phone.
Has anyone else had this issue? I tried a factory restore with no luck.

Hi,
I have the same issue , my screen turns black when calling or receiving calls , i m not really good with my hands... so do you know other solutions to disable the proximity sensor ?
thanks
Same issue here - LG G2 screen turn off and goes blank during conversations
I have exactly the same issue - LG G2 D802 screen turn off and goes blank during conversations.
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!
Another issue which I also have and is also caused by the proximity sensor is that the screen stays on and the touch buttons in the dialer aren't responsive - which means we can't switch to speaker, add a call, mute, etc... However, the main touch / navigation button (home, back and menu buttons in the bottom of the screen) are responsive, in addition to the status bar.
(This issue was already reported by @athorax 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.
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 for you it was a software issue?
Is your sensor working until today with no issues?

I'm also rooted and with TWRP.
Did it happened before you rooted?
Did you used ioroot to root andAutoRec to have TWRP?
You see, I'm really trying to find the similarities between us all in order to solve this issue...

We already have KitKat based firmware update. For me it's D80220C.
For you it might be already D80220D. Use this link to check your version, and replace the IMEI in the end of it with your IMEI.

When you place the call you do hear that the call is made?
If so - then you have exactly the same issue.
What is your model, what ROM are you using, and did you root your phone?
I have LG G2, unable to make call. The signal strength is fine. I have tried reinserting the sim. but i am able to receive calls. when i make a call the dialup screen come up and call ended automatically. Any Help
About half the time I go to make a call the screen dims (like it should), however, the call screen never comes back up. Sometimes I can return to the homescreen, but when I go back into the dialer and hit either return to call in progress or bring up dialpad, it just returns to the homescreen. This makes it impossible to end the call by myself. Is this a known issue with a known fix? I haven't been able to find anything on it. Is there another KitKat rom that doesn't have this problem?
