it is a common issue with after market screens and it has to do with the proximity sensor.
check this video on YouTube "Nexus 4 Disassembly Teardown - Screen & Case Replacement - Drop Test Repair LG E960" -- sorry I am not allow to post links yet
if you follow the steps on that video with regards to the proximity sensor, it would be installed correctly and the holes would line up perfectly between the gasket and sensors. However, that doesnt seem to work, you want to now install with the tab facing the other way, you will now see that the holes do not line up correctly and the gasket is partially covering the sensors, dont panic, that is what you want it to look like. This worked for me and for many others.

Hi folks:
Sorry if this problem has been covered before. I ran a search to try to see if I could find someone having this problem and could not find it. This problem started all of a sudden (without any ROM updates or nothing).
This is it: I make a phone call, and immediately after I press "TALK" on the screen, the screen turns itself off, and I don't have access to the keypad, or any of the touchscreen functionality.
I tried pressing all the hardware buttons to see if the screen would come back on, but nothing, it stays off.
Then, when I hang up the call (by pressing "END CALL" on the screen), the screen comes back on and everything is back to normal.
Can anyone offer any clues to solve this? Thanks in advance.
is the phone near something? maybe your ear?
is anything in front of aproximity sensor? (upper left, near speaker)

Nope... I use a BT headset since I got it (this only started happening 2 days ago, and I've used this device for over a month now).
It also happens everywhere (in my room, outside in the street, etc).
Very puzzling... I am thinking of doing a hard reset, but want to see if anyone has had this happen before...
Does it happen when you don't use the headset?
Yes indeed, I had already checked that and ruled out that the headset was causing the issue.
have you recently installed a "screen protector" ? This happened to mine as i hadn't quite got the holes lined up for the proximity sensors.
thanks,

This happened to me as well today. Had the phone for 3 months now and can't say I've noticed it before. I do have a screen protector which also covers the proximity sensor (no holes in that area), but this was like a month ago and I have had no problem accessing the screen during calls until today. I have made a couple of calls after the one I mentioned but didn't remember to check if the problem was still there. Will try to see on the next one
ive been able to just press a face button to bring the screen back up. of course mine turns off when i put it near my ear thats intended. i had an issue where the touchscreen would not work at all durung a call. the screen would be on but only the physical buttons could do anything. a hard reset fixed that
Yeap, coincidentally, I just installed a screen protector and a protective case (darn). I will try this without the case and report back.
Thank you !
Problem solved ..
Been trawling these forums for hours for a registry edit to fix screen blank when making a phone call - LOL - who would have thought it was the cheap plastic case I whacked on the other day!
Hey friends,
I am facing this problem while making calls that as soon as I press call button or receive button(while taking call) the screen turns off n stay that way till the call ends.
I have tried pressing all hardware buttons,even moved the dvp awayfrom me n into direct light but to no avial.though it did turn on once or twice out of twenty times.
Did anyone else experience this? Any suggestions are welcome..

Do you have a screen protector or case that is obscuring the light sensor or proximity sensor? My first guess is that something is obscuring one or both, because during a call the screen being off is a feature.

screen stays black/off during call
The screen stays black during a call and this happens ramdomly. I have a dell venue pro a t mobile phone but it is a pre release so it works on att 3g and all. I have switched the sd card with no improvement. I have ordered a transender 32 gb sd that I haven't received yet. The firmware version 2250.1400.7004.025 hardware is 112.576.2.0 radio soft 2.2.50.14 radio hard 8250. I have been unable to get any of the hardware keys to hang up the phone which if I get voicemail or something means I have to power the phone down to get the dang thing to hang up. Sometimes it works fine but I cant find a commonality software or hardware that causes this. It happens right out of the box so even after a software reset it can happen. Is there any solution for this issue?
I can't understand why the button on top doesn't hang it up.
PS I got this phone for free and I got ripped off LOL
wow just got a replacement phone today and im having this problem, As soon as I go to make a call the screen goes black and cant do anything on screen during the call, so i cant enter my password when checking voicemail
I think it's related to the proximity sensor. When you put the phone close to your head, the screen switches off. When you move it away, it will switch on - most of the time .
If it stays black, have you tried tapping the power button on the top of the phone? It switches the screen on without disconnecting your call.
A coworker got a replacement the other day(they send a refurb) phone and it had the same problem. Had to go through Twitter to get Dell to send him a new retail phone since they had send him 3 refurbs prior and they all had different issues.
This is just a general statement regarding phone proximity sensors. I have had multiple phones made by different manufactures that experience this to some degree (including the Venue Pro). One thing that I have noticed is that if the phone goes from your face directly into a bright light (outside is most common) it will keep the screen shut off but if the sensor is somewhat shaded it will resume normal function.
I got the same problem too and while it may be a proximity sensor problem, it is not controllable on the user's end. Unless the phone call disconnects magically, a battery pull is necessary.
I'm gonna be on my third one soon and I hope that i won't face the same problem.

Yes i recently got a new refurbed phone and this problem has arised. Complained to Dell and they are going to send me a Brand new DVP. I see a lot of people having this same issue with the refurbs. Currently Dell is out of new DVP due to them upgraing the firmware, so I have to deal with a broke phone till the end of August. Talk about a dissatisfied customer. Im thinking about selling this brand new unit when I get it, hopefully Toshiba has their device out by then
This is a Proximity Sensor issue. You can fix it though in the EM app. You can adjust the sensor readings and the phone will function like normal. Let me know if you need the values or a step by step!

A step by step would be awesome. I like being able to see the screen during a call.
1) Get the EM app, if you dont have it dial ##634# into the dialer
2) Get into the advanced menu by double tapping the black area and typing in "qwertyuiop"
3) Select "RD test", now enter *#6336# in the box that pops up.
4) Select "Sensors", and the "Proximity Sensor Config"
5) Set the following to these:
LED strength - 1
Diode select - 2
Pulse Count - 43
6) Hit set and then you are good to go!
I have noticed that one of my DVP's needs to have this put in again everytime I reboot the phone, the other saves it. Just an FYI for ya!
I get to step 3 and when i clock on RD test, I am prompted with a white box with blue trim and an X at the top right. can you advise on how to proceed?
Oh yeah, Im sorry I forgot that part. Enter *#6336# as the password.
When I dial *#634# it says thic code is not supported.
What does that mean?
I put in a different number combo before and it put me in the EM screen

Hello! I have recently installed CM9-20120319-NIGHTLY-jordan on my Defy and it seems there's a problem during calls. The proximity sensor is not working (when I'm taking the phone from next to my ear, the screen won't turn on, as it used to before in the CM7). Also, the screen remains black and won't turn on unless the other party hangs up the phone. I need some help about how should I fix this. Thank you!

Ok, I know this is really old, but I just had the same problem and want to document how I fixed it cause this is a top search result for me and I figure it must be for others too. I had observed this behavior just after installing Quarx's CM11 Nightly, and I had assumed that it was a software glitch.
Some months ago I actually managed to crack the glass on my phone, and I had ordered replacement parts. I thought I had just ordered glass, but I got a whole new case that was all shiny and new. So I swapped broken parts for new and went on my merry way. But I did notice that the volume down button was sticky, but I just dealt with it for a while. Recently when I was Rooting and installing CM11, I got frustrated with my volume down button trying to get into the recovery system, so I cracked my case open to take a look at the sticky button. I found a small plastic burr left from the molding process. I sliced it off with a razor and reassembled and thought nothing of it. Happy with my functioning volume down button I proceeded along my merry way.
Now, why was this detail in the story important? Because in between Froyo and CM11 I had inadvertently caused my proximity sensor to malfunction, by tightening the screws too tight when I put it back together. It wasn't CM11; it was me. The fix was easy. Pop off the battery cover and loosen one screw a half a turn at a time until the proximity sensor started working. Pro Tip: Dial into voice mail while trying this so you can have an active call without hassling your brother.
I only know this now because I found this video:
[Achievement Get: Thread Necromancy]
So I dropped my nexus 4 cracking the screen which required me to replace the LCD assembly. After putting it back together and firing it up I noticed that the Auto Rotation (Yes the setting is checked in the settings) and the proximity sensor are not working. I installed Android sensor box and it is getting no reading from the proximity sensor or the gyro sensor. I have taken the phone apart multiple times to ensure everything is connect and everything looks correct. I have also unlocked the phone and have re flashed the stock rom with it not fixing the problem. Any help would be much appreciated.
My wife destroyed her display. Did same but gyro works fine but proxy is the problem. Work around so far is to set power button to end calls becasue screen just goes black when making/receiving calls kind of makes phone useless if you can't see screen.
I too have taken it apart several times and still nothing. Next plan is to find a new sensor unit and replace it.
From what I have been able to see in all my searching the proxy is extremely sensitive any deviation in placement, smuge on unit or display, minor deviation on color of display, screen protector, any interference from skins can affect it so check all those also.
In one of the threads on the Galaxy Nexus there is a patch to turn off sensor and there is mention of app in market that does the same, haven't tried yet have to get phone from wife to try, could be possible solutions also.
Will post back with findings as I get to try them.
Found great app in market Sensor Kinetic Pro shuts off proximity sensor or any other sensor no more problem with black screen after making calls. Still going to try replacing sensor however found it on Amazon less then $5.00.

Somewhat comforted to see others are also having the same problem... I recently replaced my nexus 4 screen only to have my proximity sensor fail on me too. Interestingly enough, i disassembled my phone multiple times to test if the sensor still works, turns out it does, but it is super sensitive. In my first experiment I had the sensor dangling out of the socket to see if it was still receptive to light, it worked perfectly - I used my hand as a 'face-simulator' to test for sensitivity. I then tried to place it back in the rubber grommet with the grommet seated firmly in the socket and what I found was that it worked, so long as there was only limited pressure on the enclosure. For example, it only works when there are no adjacent screws (for the plastic motherboard cover) applying pressure in the nearby area. I thought I could live with that, but then I tried putting the rear plastic cover back on and,... back to square one, dead screen on-call. I figure it has something to do with either pressure sensitivity or perhaps the pressure from the screws or the rear cover pushes the sensor too close to the glass?
Anyway I'd be keen to see if replacing the audio jack will actually fix the problem, any of you guys had any success with that? Meanwhile i'm going to just use the power button for ending calls. Any tips for how to use the speakerphone during a call?
Cheers fellas.
New sensor arrived yesterday changed out my wife's non functioning sensor and new one working great. Old sensor was bad !!!! She had dropped the phone several times and last accident she unintentionally threw it. Suggest no one do that

I put a case on mine and it started working. It always would work if i put a bit of pressure on different parts of the phone. So im not sure if bad contact on sensor or if more some type of alignment issue. But it does work now. speakerphone is terrible since cracked screen tho..
Hello guys! After a long search on the recent questions in this amazing forum I couldn't find anything similar to my girlfriend problem...
Her Nexus 4 was just fine until the update to 4.3.. After that it started to show a problem during/after calls, the screen turns black completely (even when is not near the face or anything) and its impossible to do anything with the phone after that. Power button doesn't work, and there is only two ways to get the phone working again: the other person hang up the call.. or to hard press the power button until the restart...
I tried already to change for a 4.3 ROM and now I changed it to a 4.2.2 ROM... any idea or suggestions to a possible solution?
Thanks a lot guys!
I too recently had this problem. There was a simple fix after dealing with it a couple of days. My 4yo daughter had been playing with my phone after which I started having the problem. What I found was one of her hairs had become stuck in the bumper and was resting on the screen over the proximity sensor. Once I cleared that, no more problem.
The sensor is on the upper left of the screen.

If You use screen protector and it goes over sensors, than will be the reason of Your problem. Just remove it.
It could be the 4.3 update. I didn't have any such issues until the update and then they began. AndroSensor confirms that no matter what, proximity sensor is at 0.
Any thoughts on what to do short of RMA?

I can assure you its your screen guard that is creating an occlusion for your sensor on top left. Remove it and it will definitely work.

Not sure if I mentioned it earlier (perhaps in another thread) - no screen guard. That wasn't the issue. Finally, I changed the proximity sensor itself, all bueno. No RMA which means avoiding a bunch of hassles (namely new phone, data xfer, etc).
