This has been happening pre and post Nodo on my focus. If i'm on a phone call for at least a few minutes, then pull the phone away from my head, the phone's display should become active, but it isn't.
Anyone else having this issue or is it time to exchange the phone?
I have the same issue also it seems like I have to press the power button a couple of times to get it back.

I'm also having this issue. Anyone remember if ther were having it pre-Nodo? Just wondering if the update changed something.
Regardless, it's a bit of a PITA.
I experienced this after having to replace a cracked screen. I just recalibrated the proximity sensor with my finger about an inch away and it worked fine.

How did you do that?
Yeah, ditto that - how do recalibrate the sensor?
Samsung Diagnostic App.
http://forum.xda-developers.com/showthread.php?t=839154
I was pecking around the screens months ago, and there was one bank of tests (multi-touch, red, green, blue, white, battery, etc, etc) that allowed setting and viewing the proximity sensor.
I remember playing with moving my hand closer, and further and watching it change from sensed to clear.
Sorry, can't remember which codes now.
I used the Wiki:
http://forum.xda-developers.com/wiki/index.php?title=Samsung_Focus
LCD Test - *#0*#
Ok, mine says No Detection. Is there anyway to set the value?
One other thing to note, about the samsung focus specific update regarding disabling the touch sensitive buttons while in a program, that also isn't working for me either. Not sure if they are related, but thought I'd throw it out there.
And as far as calibrating goes, not sure it would help since the problem only occurs while I'm on a longer phone call. On short ones the proximity sensor works just fine.
If you move your finger closer to the sensor, it should eventually change to Detected. The "set" button at the bottom should set the proximity sensor to the new distance. Mine is around 75.

Mine says No Dectection. It has Prox Sensor: XXX I've taken my entire hand and covered my phone. NOTHING. When I push SET, It says ProxThreshold :0. Is there anyway to set it manually?
samsung focus post nodo
I believe the prox sensor issue is happening post nodo, I have never had this problem prior to the update... I have been able to fix it temporarily by pulling the battery and starting it up... don't know how long the fix works... got to do some testing... I am wondering if its a power thing as the screen wouldnt work when you plugged it in to power and had on a soft surface....
Still nothing. I didn't want to hard reset since I have Chevron installed. For some reason I did four updates on my phone and don't have a single backup. If I hard reset I'm S.O.L. with Twin Blades and other homebrew apps
What value does it show when you press the Reg button?
I've had issues with my earring tapping the screen while I talk and I had it fixed before NoDo, but the values reset when it was installed, they also appear to be different values now as my screen got supper finicky after the update. I was constantly hanging up or scrolling through multiple pages of stuff with my ear and you could see the screen turning on and off. I ran the proximity calibration while holding my hand in front and set to it to 1.
If it shows xx have you tried setting the value with nothing in front of the phone to see if it will at least zero out?

It has a big red box. It says No Detection. Prox Sensor:XXX Do I press Set or Reg?
another thing is wrong
seems like my light sensor is fried as well... I am starting to wonder if it's because of bad placement of the usb port... both lay right in front of the port, can't imagine pluging in and unpluging the phone would help if the sensors are right in front. I can't get either sensors to work anymore, even with a battery pull... does anyone else have this issue? goto the diagnosis menu and type
*#05#
you should be able to run through all the tests, I skip the feedback loop... Start at 1 and work your way through.
My Prox sensor says, no sensor XXX, and my light sensor is stuck with a value and will not change even when I cover the sensor... looks like a warranty replacement... how does this work with a sd card installed, the official WP7 ATT certified 8GB? Anyone else have to do this?

same problem here. seems like those two sensors are burned
Just wanna ask if there is any temporary fix to the proximity sensor of nexus 4.
During calls the screen doesn't turn off when placed close to the face.
I didn't get the chance to test it on stock 4.2 because when i turned my phone on it updated first to 4.2.1. Ever since then it has had proximity sensor not working during calls.
And i have never had any screen protectors on the screen.
Tried many custom ROMS as well but no difference at all.

how about kernals could be a bug in franco.
return it to 100% stock make sure its still doing it under those conditions then if it is contact Google and ask for an RMA this is probably your best course of action. if it has been like this since you pulled it out of the box then contact google right now and tell them the proxmity sensor is clearly broken
I have this issue too, but I'm on CM. Not sure if it's CM being a problem. Can someone on STOCK comment?
BTW as for screen protectors, unless you have a giant bubble or crap on your protector or underneath in the adhesive layer, the proximity sensor should perform fine. Before you blame my screen protector, I downloaded a proximity sensor app to show the readout. The screen protector with no cutout is fine. It's not optimal to have one like that, but the proximity sensor works fine.
isnt there a proximity senor app which lets you test it on the market?

There is.
I've installed and tested.
According to the app results, The proximity sensor seems to know when my hand is on it and when its off it. The value changes from 1.0 to 2.0
It just won't work on phone calls.

It doesn't seem to be a hardware issue.
Sensor tests were made and the proximity sensor picks up when my thumb is placed on it.
Problem is on phone calls alone. Right from stock ROM to CM, PA, Xylon, AOKP, almost all of the ROMs.

Mine is stock and during calls it usually goes to my settings menu and changes my clock setting. When I get off the phone, screen is blank and I hit power button to end call. Still annoying at times when the clock changes.
any luck with finding a fix for the proximity sensor? Mine never works when I'm in a phone call. I have to either wait for the call to end or reset the phone by holding the power button to end the call.

I think it's a bug and not a hardware issue. Perhaps one of the other reason for having a new factory image soon.

Yes I think the fact that the app testing showed the sensor working so it points to software. Something is missing when the phone is in a call its not connecting to turn off. I thing Jellybean was flawed in many ways. My drop down brightness slider doesn't work for me nor auto brightness its OK for me cause I don't use either but still makes me mad.

Same problem here. Nexus 4. Stock Android 4.2.1. No screen protector installed.
While I'm in a call - the proximity sensor seems to work, as the screen goes dark... but at the end of the call when removing the phone away from my face, the screen does not come back on - making it impossible to hang up on the call (unless the caller on the other end hangs up first). It also makes it difficult to impossible to switch to and from speakerphone in the middle of a call.
Pushing the power button when this happens doesn't wake the screen either... sometimes it flashes but then goes black again. It doesn't happen on every call... maybe 75% of the time it does happen though. I've installed the proximity sensor app and it seems to recognize "covered" and "uncovered" states correctly when I cover the sensor at the top left corner of the phone while not in a call... so I'm thinking this is actually a software issue with the sensor and not a hardware issue. Drives me nuts though.
I've set "accessibility settings" to have the power button hang up calls as a temporary workaround... we'll see how that works.

Having the exact same issue here too on stock ROM.
Good idea on the accessibility settings! Will work until/if they fix it..
Also no screen protector.
I had the opposite problem to this where my screen would stay off during a call and I have to force restart to regain control.
Turns out it was the rubbish screen protector causing the issue. This was quickly fixed by cutting the screen protector so that the sensor was uncovered.

It was the same fix for mine when I first got my bse it worked fine for about a week but then over time it got worse. It was the screen protector just that lil bit worth of it wear caused enough blockage of the sensor. I got some new bse's and they now have a cutout for the proximity sensor and are screen optimized.

I do not have that issue, but I have read in a few posts that it can be dependent on where you are knocking on the screen.

I think the biggest issue is knock speed.... mine works damn near 100% when I slowed down some, and knock slower like it showes at the end of the G2 commercials....
I think it's partially related to the proximity sensor. There are times when I can't get the knock on to work at all and when I hit the power button the screen shuts right back off.
Usually a few swipes over the sensor makes it work again. Sometimes I'll go in and turn the Knock On gesture off and back on and then it seems to work great for a while too.

This is my exact problem. The phone just decides it doesn't want to wake up with knock-on...but after I press the power button, it only turns on for half a second and it's out again. I never tried swiping over the sensor, but hopefully it works because it's mighty annoying when it does it during a call!
I wonder if there's a fix for this?

this, if you are trying to do it like you did on the nokia n9 or nokia 8800 then it won't work
slow deliberate knocks are the only way
waiting on the g2 to arrive, but on my review unit, knock knock wouldn't respond correctly if i left the phone on the table, but if i picked it up, it would work nothing scientific here just an experience of one person and one prototype
I had the same issue... What fixed it is: 1. I found that the screen protector was hindering it somewhat. 2. Go to settings->display->screen-off effect-> and change it to simple. This REALLY seemed to help. Let us know!

I did notice it does seem to behave better when set to simple for the screen off animation.
My screen protector does have a cutout around the sensors. Keeping the sensor area clean enough to qualify as having OCD does seem to make it work properly the first time, every time. Maybe it's overly sensitive?
Edit: Scratch that. 30 seconds later it's behaving erratically again. Maybe it's not the fact that it's clean, but the swiping over the sensor that temporarily resolves it.
it also seems to work much better when knocking at the top of the screen where the statusbar would be.
So I ended up swapping the phone out over the weekend for a new one and now everything seems to work just fine. Seems to indicate that it's not a software problem, but rather a hardware issue with the proximity sensor.
Guys if your covering the sensors when turing the device screen on it will turn right back of on you. It's a feature LG implemented so the device wouldnt wake up in your pockets. Don't cover the sensors.
Need a little example? Grab your phone and cover the sensors and knock knock knock.You can knock till the cows come home but it will not turn on. Same thing goes for the power button but its a little delayed and will turn the screen on for half a sec and turn right back off. Practice not to do this because your phone isn't broken. There is actually a thread on this deep in the forums somewhere but its been forgotten now.

This is true however there are indications of problems with the proximity sensor as well. Some of the devices are behaving as if tree sensor is covered even when it's not.

Thanks for this.. Very insightful.. I tried it immediately LOL
I had the same issue. I have no case or screen protector on, and was not covering the sensor when trying to wake the phone. For some reason though, knocking wouldn't wake the phone, and pressing the power button would only turn the screen on for a few seconds. I want even given enough time to get past the unlock screen. I went into the store and they are sending me a replacement that should come in later this week. It doesn't happen all the time. It is much more noticeable after receiving a call though.

Definitely is dependent on the proximity sensor. If i just have my thumb on the edge of the phone by the sensor it will display this problem. Even with my finger a half to one inch above it will do this. I will be paying close attention to the proximity sensor from now on when it doesn't work. Still have a few days to return and thought i had an issue but maybe not.

As long as you tap twice the same place it's working fine. If distance between first and second tap is greater than 1 - 1.5 cm it won't work.
Got the same problem on my d802...when i left the phone on my table for 2-3min it wont wake up on first knock knock even power key wake it up for 1sec after auto turn off again....even with no screen protector....i noticed that sometimes there is a delay about 5-10sec after knock knock and screen turns on....other thing i noticed when i knock on immediently after turning off it works 100%....BUT i also noticed when i knock on after a while it turns on and i can unlock got vibration and sound of the unlock but i cant see anything. Screen looks like its off but when i look closely i can hardly see widgets and when i set effect to tv out i can see the effect by pressing the power button...when i press the power button again screen turns on like normal...i noticed sometimes on a rerboot the lg bootlogo disapears the led is working an showing all colors but the boot animation is gone like the screen is off at the bootup...dont know why after the bootup the pin lock screen is showing up normal....sorry for my english^^

The screen is supposed to go black when you make a call--or, rather, when you place the phone to your ear. There is a "proximity detector" along the top edge of the screen, and it detects your ear when your ear gets close. The phone then turns off the screen sensors so that your ear or your cheek doesn't push any buttons while you are talking, and turns off the screen illumination for aesthetic reasons. However, the proximity detector is supposed to cause the screen to turn back on when you remove the phone from your ear. That isn't happening for you. When it didn't happen for me, I took it to the shop. The tech said the proximity detector was broken, and ordered a new one. But replacing the proximity detector didn't help. He finally disabled the sensor so that proximity was never detected. that worked.
This story does not have a happy ending for me. The phone worked for a couple of days. Then I tried to reboot, and it went in to a boot loop. None of the standard cures for a boot loop is helping me. I doubt if the two problems are connected.
Proximity sensor turns off screen when you put it to your ear to avoid your skin touching the "End call" button or something else

Ok, was worth a shot...
Then you must likely have a faulty proximity sensor, as stated previously.
Download an app, like AndroSensor, and see what the output for the proximity sensor reads. When nothing is covering the sensor (top left corner) it should read 5 cm/2 inch, or something similar. If it reads 0, it's busted...

Hmm... The plot thickens...

I have the same issue. In my case, the proximity sensor may have been broken or blocked by dust.
My "temporary" solution is using the power button to disconnect calls. While using a Bluetooth headset, the screen can be turned on. I hope there is a better solution.

I bought a used V20 with a defective screen. I change it, everything work for fine, but i notice a strange behaviour with the second screen.
The second screen is always on and i can unlock it by only touching the finger print sensor. BUT at night (or in the dark), the second screen turn off and i need to press 2 times on the power button to wake the phone.
The Knock On feature doesn't work too in the dark.
The light sensor seems to work correctly.
I would love to post a video but i can't......
This is an issue or it is normal ??
Thanks for your help !
Sounds like Doze.
I don't find anything related to Doze or "standby" about this screen.
check "daily timeout" on Show when main screen off. Seem u turn this function on at night

Sounds like there is an issue with the proximity sensor (not light sensor).
It's setup to turn the second screen off as well as disable knock on if the phone is in your pocket. Even during daylight hours if you put your finger within an inch of the sensor when the main screen is off, it should trigger it.
It seems your sensor may just be messed up.

There are a few apps on the play store you can try to fix it if you are rooted. You could also try a sensor app to see if the proximity sensor is showing feedback properly although you might need to be rooted for the apps to show the proximity sensor properly (not sure). My note 4 had a hardware test in the service menu not sure how to do it on V20 though.
Same Issue
Edit: Resolved the issue. Please read this post. There is a small rubber gasket-type thing that sits in the hole of the phone's frame where the proximity sensor is positioned. That rubber gasket was not included with my replacement screen. I pulled the rubber piece out of my original, broken screen, and installed it into my replacement screen. I am no longer having issues with the phone in the dark.
I am experiencing the same issue. I have a T-Mobile LG v20 (H918) and I cracked the screen last week. I ordered a replacement LCD assembly and installed it myself. Everything works fine during the day or in a well lit room, but at night, in a dark room, I experience all of the issues you are reporting. I am finding other posts online with our same issue, but as of yet, no resolution.
Even though the second screen is set to always be on, at night, in a dark room, it turns off almost immediately after locking the phone. It is almost as if the phone is in a "deep sleep" or something, because the following also occurs:
Knock On will not wake the phone
Fingerprint sensor will not wake the phone
Even connecting to the phone via AirDroid / AirMirror the phone doesn't wake
Need to press the power button multiple times to wake phone
Providing a light source immediately turns on second screen and resolves all issues
