Posting this in hopes that it will help someone else.
About 2 months ago I started to have problems with the proximity sensor on my N2. When I would answer an incoming call, the screen would go black, and I couldn't get it to come back on, without waiting about 2 minutes or doing a battery pull. After doing a little research, I found an easy method to recalibrate the proximity sensor. This worked well, but it had to be done every time the phone was rebooted. So I set up a gscript.
Recently did a little more research and found a recommendation to use compressed air and blow into speaker grill (where prox sensor is located), to disperse the lint that accumulates from carrying in pocket. This worked like a charm, and solved the problem, completely.
Edit: After several reboots, the data connection issue remains. Sorry if I unintentionally misled anyone. Proximity fix is still ok, though.

Hi everyone,
funny thing happened to my Mozart. Whenever I make a call the screen shuts off like it should, but it doesn't turn on again when i remove it from my ear until the call has ended.
Which works fine if the other person hangs up, but it means I can't hang up. Whenever I reach a voicemail i have to take out the battery to hang up!
First i thought it was a rom issue, i had just gotten my hands on the mango beta when i first noticed it. I thought it might be buggy.
But the problem remains after hard reset and flashing with a different rom (pre-nodo & nodo).
I found out that the sensor still works. The screen is reactivated when i shine a bright light (halogen spot or so) onto it - but only for as long as the source shines onto the sensor, else the screen shuts off again. wierdly enough, direct sunlight doesnt seem to be enough to trigger it anymore.
since i upgraded my phone with a 32GB microSD I guess I'm not eligible for warranty, huh? but im pretty sure it happen long after and i didn't accidently break something while opening the phone.
very weird... any ideas?
I had this problem on the weekend.
I removed the matt screenGUARD, and the problem disapeared.
Also you can reactivate the screen by pressing the on/off button...
thanks for your comments.
unfortunately, I don't use a screen protector and the standby-button doesn't work during a call
I have this problem also, with stock 7392 rom. The sensor seems to work when dialing, but stops a short time after a call is connected.
The power button works for me to turn the screen back on however...
Where is the proximity sensor ?
where on the device is the proximity sensor located?
I have been having difficulty with the screen not switching on during phonecalls and I have to remove battery to end outgoing calls. Pressing the power button doesn't help either. I don't have a screenguard to remove.
The problem started not long after, but not immediately after my daughter dropped the phone down the toilet. It took a few days for the phone to gently dry out and it worked again except for some residual water between the screen and the glass.

The sensor is about 1 cm to the top and right of the htc logo. It's barely visible and it is dark violet. (Or something like that, I am not very good at naming colours.)
Anyway, I sometimes also experience problems with sensitivity with HTC Mozart, mostly during calls, especially when the proximity sensor has been activated. Sometimes the home button freezes after a call... It's a bit annoying.
Did a quick search for this but most posts are on a similar but different issue.
During outgoing calls, the screen rarely, if ever, turns off due to the proximity sensor - I need to manually do it using the screen lock button.
However, with incoming calls, the screen turns off fine (due to the proximity sensor).
For both incoming and outgoing calls, it is often impossible to get the screen to light again once it is off.
Initially I thought my proximity sensor might be faulty, but the proximity sensor works perfectly in the diagnostics app. So it seems to be a software issue.
Is anybody else seeing this issue? Any solutions? I have the latest 1600.2487.8107.12070 update.
EDIT: Seems to be better after a hard reset, still not perfect though.
Same here

I can't replicate your issue. Might be that you are somehow obstructing the proximity sensor with your hand.
Also don't have this issue. I find the proximity sensor to be actually oversensitive at times.
It toggles on as much as 5+cm away.
I've the same problem. I think the problem is due to the placement of the proximity sensor, not software fault. Proximity sensors should be placed as close as possible to the earpiece (i.e. the centre) of the phone, but stupid arse Nokia, with their billions of years in phone design experience, decided to place the sensor in the far-right of the top edge of the phone, so it doesn't register many times. Never ever buying a Nokia phone again, just out of the rage of wasting $500!
Disappointed by Nokia Care
I had a similar issue. Screen blacked out on incoming as well as outgoing calls and would not light up no matter what I do. It would be back to normal once the call was over.
Had to go to Nokia Care. They took my phone for 10 days and sorted the problem. However, they left marks on my sleek handset - chipped off the beautiful polycarbonate - as they probably opened the screen from top side. Also, the battery life has gone down from ~30 hrs to about 14-16 hrs.
Don't feel like going to Nokia care again as I dread what might happen this time around.

If I were you, I'd refuse the take back the handset and ask for a replacement. It's unacceptable that Nokia Care damage your handset.
Yea... I should have done that. But I didn't notice it then and was more busy checking whether the screen issues was solved. Don't think they will entertain a request for the same now... I will try though.
Rezound is S-0ff.
Makes calls and allows view of keypad during calls fine with G-Bread.
However;
Did latest ICS leak, and phone won't stay lit AT ALL during calls.
Can't press "3" now because I can't see it anymore. Sometimes have to
pull the battery to get out of a call.
Last nite late I reinstalled my last nandroid of GB after doing 2.01RUU.
And now the proximity sensor is fine again.
Do any of you ROMmers have an idea, or is this specific to 1 phone?
A lot of people have reported issues with dust in the sensor, me being one of them. I piped my phone open to recolor the softkeys, and cleaned out the sensor while I was in there. Now it works great. Maybe it is just a difference in the way the two use the sensor? Try blowing it out with compressed air.
if could be that the rom you are using has a ro.rill that may delay blackscreen i was testing my rezound today and figered that out

I did the exact same thing and it worked. After I installed ViperRez the phone would sometimes stay lit going towards my ear, then go dark when I took it away. Pretty much opposite the way it's supposed to LOL. Then I read (on XDA) about dust getting in the sensor area, just below the earpiece speaker just below the speaker and a little to the left of the Verizon V logo. I wiped it clean, then when I got home I CAREFULLY blew it out with compressed air, and that did the trick. I haven't had the problem since.
I noted each time I make a call, the display immediately turned black. It auto turn black without me even taking up the hone up to my ears. I needed to press the power switch to have the display lit up again. Is this a proximity sensor defect ??
Same issue

Yea I'm dealing with the same issue on my at&t model, it's definitely a proximity sensor issue. Also, I find that the proximity sensor functions relatively OK outside of the phone app when I'm on a call in terms of lighting of fading to black...I haven't found a fix yet, hopefully it's a software issue though somethings telling my it's not... Just another defect in a long line of LG phones as of late

I have a same issue but clean the proximity sensor and it will work. The proximity sensor is next to the speaker. Clean with your t-shirt or jeans.

I've cleaned it several times to no avail
I have noticed occasional "quirkiness" while in the phone app, but not to the point of requiring a battery pull. Example, connected via Bluetooth, while plugged to a charger in a call, no way to wake the phone without pulling the charger.

Thank you. Thank you. Your proposed solution works very well. Now no more this problem. Had never thought the sensor could be dirty or blocked over time. I had the phone only about 2 months
Problem update
Okay, I've found new info on the proximity sensor problem. Firstly, I noticed that my proximity sensor still works with the second screen, if I cover it up when my screen is off it goes black and comes back on when I remove my finger. Secondly, if I was on the phone but not actually in the phone app it would behave normally sometimes. Now today I found out that when I'm in the phone app, if I'm talking on the phone through the speaker the screen does not go black, as soon as I take it off speaker, the screen goes immediately blank. Still have not found a fix, but just more info that may help define what the actual problem is.
anyone have any update on this? this issue seems to be getting worse for me
Same issue, drives me nuts. This phone is a disappointment to me overall. Have an S7 on pre-order with Verizon. Can't wait to get my hands on it!
Had same issue just happen on the AT&T LG Escape 2. (Yes I know its a year since this thread was started)
It was the proximity sensor but the "T-shirt wipe" method didn't work for me.
What I did realize there was some gunk on the sensor, and I used a cotton swab (Q-tip) with alcohol and rubbed it till it was visibly clear of gunk. Now it works fine again..

Turn of Gestures
Was facing the same issue
Went into settings

Turn of both gestures auto answer and flip to silence
Another thread about this stupid sensor.
My screen goes black when I call or answer a call. If I use a headset sometimes randomly the screen comes on or stays on when I answer a call.
The proximity sensor is working. Looking in *#*#7378423#*#* > Service tests > Ambient Light Sensor.
Putting it to a lamp gives a value of 10.0 and putting my finger over the sensor gives 0.0 .
So its working.
This seems to not be rom related if not for the change after Android 4.4. I flashed roms from cm-12.1-20161016-NIGHTLY-togari.zip, AOSP_N_161207_togari.zip and now I am on hybrid_concept_edition_2.0.zip.
I do have a screen protector on. But with a hole for the sensor. Its not dirty in that area. And the sensor worked fine way before I installed it.
This started happening during the last two months or so.
I tried numerus of apps from play store. None did anything. Of course I could force the screen to be on. But with the risk of pushing some buttons when I'm in a call.
My temporary fix so far has been to enable end call with power button
Do you have any idea what to do?
Thank you
I'm facing this same problem, I'm on stock.

yup.. I had mine apart today. But you need to remove the battery in order to flip the motherboard around to get to the connector.
I don't have time for that. Perhaps the battery will explode if I try to remove it..
So I cut a piece of foam plastic to fit around the usb connector so there is a constant pressure applied to the motherboard when screwed down the NFC antenna because there is a screw just around this area that sets the NFC antenna in place.
Hang on. I just made a call just for the sake of it that you answered to my thread and it freakin works!!!!!!!!!!!
I got the idea from this guy/gal: https://forum.xda-developers.com/xp...olution-proximity-sensor-fix-z-ultra-t3595525
