When receiving or making calls the phone turns off when it approaches the ear. I understand the reason and like this function - so prefer not to uncheck this. I also understand the proximity sensor should turn the screen back on when the phone leaves my face (this used to happen).
Now, the phone stays black the moment the call is dialed or answered. I can press any button on the phone and it stays off. This presents a few problems 1) I can't dial through menu IVR menus, 2) I can't hang up calls (had to pull battery a couple of times), and 3) cannot due things like mute/unmute.
How can I get it, that if the screen is off and I press a button then the screen turns of (or the proximity sensor to work correctly).
Again, this used to work just fine - it's only recent (no changes to the phone have been made). The screen is clean so nothing is blocking the sensor.
Thanks
chances are you have a bad proximity sensor. I had the exact same symptoms and luckily still within the 30-day exchange. Try downloading android sensor box and test the sensor. I think the sensor wasn't glued tight because If i squeeze the sensor for a good 15 secs, it will work correctly; however, the symptom will return within a few minutes.

That answers that question. I am not within 30 day period, but within 1 year and have warranty.
Thank you!

Hi guys,
Ill start with saying that my english is veryy bad
But my problem is:
I quess my light sensor on my hd2 is almost defect.
why?
When i start a call (or got an incoming call) the screen turns black
(as its suppose to be when you hold it to your ear)
But it turns black all the time, no matter how i hold it.
So i did a quick test, i called a number, and took a very bright light (100w) just next to the sensor. and after that, it doenst turn black for the first time!
So the sensor isnt working correctly anymore?
It is since my telephone has gone back to the shop for a new screen.
Can i make it better with software? Cause it works.. But only with a very bright light.... Or do i need to get back to the shop?
thnx
try a soft reboot and then if needed a hard reboot/factory reset. don't forget to back up the phone first as it wipes the phone
Sorry, i was forgotten to say:
Ive tried different roms, and even Android. Results are always the same!
That is an odd problem. Especially since the ambient light sensor is not what is used to black out the screen during calls. That would be the proximity sensor.
If you look very carefully just to the left of the speaker at the top of the phone you will see the proximity sensor. Do you have a case on your phone that may be blocking/interfering with this sensor? Do you hold your phone in a way that your fingers or hand may be close to this sensor?
Another thing to try is put the call on speaker phone, this should disable the proximity sensor and keep the screen on. If it does not then you may potentially have a hardware issue.
I haven't got something blocking the sensor. But because my screen was broken, they placed another one. (And since then it happend)
Ok, i did some tests..
I cleaned the screen very proper. And i was sure there was no spat of dust or whatever. so i called again.. And it worked properly!
But.. When i put my finger on the sensor.. (So its not 100% clean anymore) it turns black again. So its veeeeery sensitive..
When i turn on the speaker.. It doesnt turn black..
So conclusion:
It turns back way to fast. Only when the screen is 100% clean, and there is enough light in the room.. It works properly..
Aren't there any settings for windows or android to change the sensitivity? Cause this is very annoying..

Not that I'm aware of. It sounds like they didn't do a proper job of replacing the screen. The ammount of light in the room should have no impact on the screen turning on/off. Also, my screen is often quite filthy and I've never had that trip the proximity sensor. It is possible that the sensor was moved or misaligned during the repair.
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.
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
Call
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
