Hello,
I just got my nexus 4 yesterday. I have one major problem, when I'm having a phone call, I am not able to turn on the device (to check anything in the phone or even to close the phone call!). If I click the power button, the screen turns on and off instantly as if something is getting close to the proximity sensor.
How can I fix this? (I'm thinking if there is a way to disable the proximity sensor during the call?)
Nexus 4 16GB running stock 4.2.2 (latest)
Do you have a screen protector on it, without the sensor cutout?? i use to have the same issue...but later found out it was due to my screen protector

I do have a screen protection.. I placed it to align perfectly with the camera hole. It's made to be on the sensor so I figured it should not interfere. I'll try cutting a part of it to test.
Problem fixed after removing screen protection. New problem: I need a screen protection now.

Has anyone installed the HC SP300 screen protector - if so does your proximity sensor work.
I noticed today that when i make a call, the device blanks the screen after pressing the send key. Putting it to the face and away does not make the screen come on. I'm guessing its the screen protector as i just did a hard reset and still not working (although it did when i got the phone.
I install the HC Sp300 on my device and the proximity sensor still works fine.
OK thanks.
Guess im going have to remove it to find out if it is the screen protector. If that doesnt work, i guess i have a dead sensor?
I have the same problems. It seems to be working, but with the more light.
I had the problem of the black screen when a call connected.
To solve it, i cut a small section near the 2 small holes in the top left corner.
Now it works as per usual. I think its a case of 'if you dont align the holes on the screen protector precisely', you will get this problem.
hi
As soon as i make a phone call my screen goes off, now on my iphone it used to do this only when the light sensor was covered. to bringthe screen back on I have to press one of the black buttons in the bottom of the phone, is this a fault?
I had this problem after fitting a screen protector. removing it solved the issue for me.
The genuine HTC Screen protectors have 2 holes in for the sensors. I can confirm this does not affect the screen when making a call.
Are you using a screen protector which doesn't have a hole for the proximity sensor etc?
It may be it can't function right as it maybe seeing the protector as something close to the sensor, hence why the screen goes off.
I have a Vidocq screen protection and the phone wake up again when I finish the call...
i tried to search the forum with no results btw
have two cases while receiving/calling with hd2
1. via bluetooth headset - even when the phone is in the pocket some apps starts randomly, even call is disconnected - isn't proximity should cause phone scrren to be blank all time?
2. via the phone - sometimes while talking screen is still dark and pressing eg. home key puts display on. sometimes moving phone away from ear turns screen on.
do you have some or its something with my phone?
I have the same problem, the proximity sensor does not work, I think it works only outside when you have strong light, try it and let me know.
make a call the screen will go off now move it from your face loking up at the sun outside you will see that the screen will turn on.
it works only when I makes a call. when I am getting a call it atays on.

Well you would be wrong then.
It's a proximity sensor, not a light sensor. I just made a call in my darkened room and the proximity sensor functioned flawlessly.
thake the screen protector out or cut it and the proximity sensor will work perfect.

Wow who would've thought that covering up a sensor designed to sense when objects are close to it would impede its functionality.
Your revelation hepled me fix the microphone on my phone. It wasn't working, and then I realized I had my hand over it!
Yes I have had issues even with the original HTC screen protector which has two small holes directly over the sensors. I finally had to remove it.
Cutting the protector I have not been very successful so far. This creates sharp edges and the protector tends to peel off from that point. For the time being I am relying on the fact that the screen on the HD2 is scratch resistant enough that with normal care it would not get scratched. With over 2 months of use without a protector my screen is still scratchless.
IF it is anything to do with the screen protector, then there are plenty out there that don't have this effect.
I've got a protector on my HD2 and have had it there since just after I got it, so just over 2 months now. The screen protector has worked perfectly, even, kochavy, in the dark, because it detects proximity not light.
I suggest removing any screen protectors and seeing if you still have the problem. If you do, send the phone back as faulty. If you don't, get a better screen protector.

do you have the original HTC screen protector with the two holes? there are some protector that does not cover the top of the phone and leave the two sensors out from protection.

No I don't. The one that came with it never please me much, so I bought some better ones.
The protectors I have don't have any holes for the sensors at the top, but like I said, it just works perfectly. There's a lot more to this issue that just the screen protector, as some people have reported that it works perfectly when they ring certain number, but not when they ring others. From what I've read on other threads, this is commonplace for people who are having this problem, so it's obviously not an issue with their screen protectors. It sounds like a software issue to me, but since it can't be identified as such, they should just return their phones as faulty and hope the replacement doesn't have the same issue.
It would be interesting to know if the people with the described issue have upgraded the ROM to 1.66, as this seems to have fixed a whole slew of issues.
Sensor works by reflecting infrared light. There is small IR lamp with IR detector nearby. You can check that by looking at the sensor through some digital camera or camcorder, whose are usually sensitive to this light. Don't forget the phone must be in call, otherwise the sensor is turned off.
I think the sensor itself is OK. But there seems to be some relationship with guess what .. G-sensor ! Once I found the screen just won't go off during call, and it was when I was lying during the call, and I was holding the phone upside down portrait style.
But as I turned the phone to normal position (normal portrait) and back, it started to work with no problem.
I only had problem with proximity sensor once since then .. but rotating the phone up and down helped again.
I think this needs more investigation .. if you encounter the problem try this.
Any thoughts on how to troubleshoot this? I have a Moto X Pure 2015, no hacks/mods/etc, just straight up as it came, but the display does not shut off during a phone call. It is as if the proximity sensor is not working, but I downloaded a test app from the Play Store and it shows that the brightness AND proximity sensor are working fine. I saw some mention of an option in the phone app to enable/disable the proximity sensor but it is not there on this phone.
One additional thought... I saw some things related to bluetooth, and I do have a Zenwatch2... I shut it off, and the screen goes off now.
How messed up is THAT? Any way to fix it?
On mine it was my screen protector combined with my case. The case caused the screen protector to lift slightly at the edge and screen stayed on so I took case off... Bad call, dropped phone, cracked screen. I replaced screen and now use my case without the screen protector.
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
