Both screens turn off from time to time - LG V10 Q&A, Help & Troubleshooting

Hello. I have weird problem on my Lg V10 H901. On 2 to 3 days it happens for both screens to turn off, and you can't wake up the phone with double touch or with power button. And I'm sure that the phone is working because I can feel vibration feedback when I press and hold power button to go in to power menu. The cure is to pull off the battery and put back on and start the phone. For two or three times it happens to show white screen with little colored dots on it when you power on the phone. Otherwise the phone works normal. . No glitches, no heating, nothing. It just go off when it sits on desk and won't came back till you pull off the battery. I don't believe it's a screen because when it happens the both screens go off. Could it be the motherboard, processor or memory, or it's something wrong with proximity and light sensor? Any suggestions?

I had this problem as well until my proximity and light sensor completely stopped working. The sensor is not detected anymore but the issue stopped after.
I don't know about the cause but it could be because of proximity and light sensor.

Thanks for the reply. I am suspecting proximity and light sensor also. I am thinking to order a new one, it's like 9$.

By the way, I feel it is better without proximity and light sensor. Many problems were fixed after it was obsolete.

I am used to automatic light. Anyway I have ordered a sensor from eBay for 6,50$ so we will see.

[Q] Sensor issues?

Hello there,
Recently I had my digitizer replaced and since then, I am having very weird thing with the screen turning off as soon as I am making a phone call. I thought it was a light sensor but in winmo it seems to be working fine, makes the screen brighter or darker depending on light. I hope I was able to explain what the problem is.
What could it be?

Doesn't that basically mean your proximity sensor is working correctly?
The proximity sensor turns off the screen during a call when it senses something close to the sensor.

Have you checked your battery contacts (pins) when the battery is removed? If they are bent, they could lead to weird screen/phone shut-downs.
Did you replace the digitizer by yourself? Or did you have someone else (like a professional) replace it for you? Something might have happened to the electrical wiring, or there might be some small piece of dirt/object that got stuck in front of the proximity sensor.
Best wishes -- I hope you get this resolved.
Hi,
Digitizer had been fitted by technician, I said the same to him that its some sort of physical issue causing the screen to go off whilst making a call. Bathe suggested its a software problem. However, if somebody came across with this sort of issue please let me know how to fix it.

I've been having this issue myself for a while now, after first installing the latest norwegian rom straight from htc, and now using the energy rom. I haven't had any hardware in the phone replaced tho.

Strange behavior when dialling

Hi I have just got a HTC radar as a company phone and am getting some odd behavior when dialling
Sometimes it works like expected other times when I press call the screen goes off and will not come back on no matter what I do until the other end pick the call up
Now that's not so bad until you call voicemail when nothing makes screen come on ie tried moving away from anything (in case proximity sensor turning it off ) tried the on/off button volume even camera button nothing works so I can't press option 1/2 etc
Only way I can end the call is to remove bottom cap and take sim card out
This happens on around 50% of all calls and is really bugging me , if its connected to a bluetooth car kit ,the car kit can end it ok
Everytime on bt kit the screen goes off with pressing call
Anyone else having this problem?

Nope, mine works perfect. Sad to hear tho...
Had that problem with my dell venue pro. Its a fix for it that I found under the dell venue pro forums of xda. Not sure if u can get the same access for the htc

Do you have a screen protector? If so it could be one of poor quality and is interfering with your screen. Remove it if you got it. Also it can mess up your ambient light sensor/proximity sensor.

Have reset device still the same I'm guessing it has a problem , sad to say but HTC aren't impressing me lately even thinking of replacing my sensation with a galaxy nexus soon :-(

I'm having the same issue too. But i do have it all the time, with every single call i make.
Lets test something here:
Grab a flashlight and turn it on
Cover the light sensor in the upper left with your finger and make sure the 3 capacitive buttons light up.
Uncover them
Now shine the flash light directly into the light sensor
Did the lights turn off? If not get your phone replaced. If they did then you or something is covering the light sensor. The light sensor can turn the screen off at around 1".
I wrote to HTC, they replied after 1-2 hours:
"this is a functional problem caused by a sensor inside the phone" ... "if you can please do get a replacement phone if you have just bought the phone"

Tried this but nothing happens while call is active , I rang someone today got their voicemail I left a message but after my message I couldn't end the call I had to connect it to my car kit and use that to end the call
Time for a new handset here as well I think :-(

For me, the light turned off. In fact I do not need to shine a torchlight. If I cover the top part of the display the 3 capacitive buttons light up. If I uncover, the light disappear. Any ideas? The screen is turning off every time I make a call.
That tests the ambient light sensor(s) - most phones have 2 or 3 - but it doesn't test the proximity sensor... (because the button lights should be tied to the ambient).
Either way, I have not heard of this issue, though HTC has pushed out a firmware update over zune for the Titan recently. I'd recommend to check that, and if there is no update/doesn't fix, then replace the phone.

Is my sensor working properly then? I have a screen protector installed. Is that the problem? I have not tried taking off the protector yet.
You should try that. Some cheap screen protectors can mess with it. I know this was the case with some protectors on the dell venue pro early on.

o.0!? The proximity sensor is normally a led rangefinder in the infrared frequencies. Light sensor could cause lots of false positives...
Sent from my SGH-i937 using Board Express
Fixed the problem. You must remove the clear stock screen protector...it distorts the sensor.
I've been saying that all along
I did a test. Peeled off a bit of the screen protector, enough to expose the sensor. Made a call. The screen didn't blank. So it's the screen protector.
Hi guys I have just recently bought a Radar from bay and im having the same problem, but this time there is no screen protector.
If I cant get a refund form the seller, can I get a warranty repair seeing as though im a second owner?
Cheers

[Q] Proximity sensor

Right after I replaced the rear camera in my phone it seems like the proximity sensor died as when I try to call the screen immediately turns off and locks until the call has ended.
Proximity sensor finder indicates that there is an object 3cm away but there is nothing actually there and the indicator is just stuck on 3cm.
What should I do?
I'm on cm9 btw.
Bump
Same issue
I have my stock camera and run CM9 AOKP, and I have similar issues with the proximity sensor. I read somewhere that it was an issue with CM in general and always discounted it as such. I did set up volume rocker wake and use that to wake the screen on call.
Do you use facelock? Try disabling it. Its a well known bug in CM9 that effecting proximity sensor...
Sent from my MB860 using xda premium
Using the volume buttons doesn't wake the phone.
Note sure what facelock is.
Thanks for the answers.
my wifes proximity sensor started acting up along with many other problems. this all happened right after the last OTA update. I sent it in to moto for repair. I was suprized i didnt need a reciept. I bought it on cl used. went to motos site and they showed me how to check if warranty was still good
Phone was imported so no warranty is available.

Ok, I figured and putting the proximity sensor really close to a light source makes the screen wakes.
Also, using proximity sensor finder I did see that the proximity sensor responds when putting it really close to the light source.
It seems that while replacing the back camera, the rubber cover of the proximity sensor fell off. Is there any way I can replace it or improvise something that might suite?
Thanks.

[Q] Please help me ...

Basically, out with my daughter at the beach today and dropped my phone in the only tiny shallow pool of water around!
It was in there for about a second at most, coz I grabbed it out SUPER fast, gave it a shake, blew all over it, wiped it down on my nice dry top I had on etc.
2 big nasty gashes in the screen, but luckily I had a screen protector on!
But, they were really nasty looking things and just couldn't pluck up the courage to take off the screen protector until I got home, as I was 100% convinced screen was gonna have at least a couple nasty scratched bits etc.
However, got home, took off protector...PHEW, screen was still in perfect condition, so was the bodywork/chassis as I had a case mate on it.
Everything seems fine with the phone, apart from to the left of where it says 'htc' the is a constant red light that stays on no mater what.
I think this is the proximity sensor?
Any ideas how I can get this light to go off and stay off??
Really guys, ANY help would be sooooo much appreciated.
Thanks
Matt
Yes, on the right of the htc bezel is the proximity sensor. Even if your daughter dropped the phone, I don't think this affected the sensor. Does it stay on even if you turn the phone off? If not then I am sure some app is using it.

On the LEFT side of the htc bezel there is a red light that stays on, but if I turn the phone off, then the light goes off.
It's only happened since I dropped it in water today.
Any ideas?

But it sounds really weird that a damage could cause it. Seriously. Please ensure there is no app running in the background which reads data from the proximity sensor. One time I was using some app, don't remember the name, never mind. It had an option to make use of the proximity sensor. Even if I turned it off, the proximity sensor was on all the time. Disabling the app/uninstalling it fixed my problem.

I know what you mean, the app is Called Viber and some users used to experience that using that app.
I've never used Viber and have checked all other apps. No result.
I downloaded Elixr 2 from the market and ran the Proximity Test.
Don't know What it means, but here is a screenshot of the result:

Any more really is super appreciated.

Just wait until you make a phone call, then you're whole world is going to go upside down.... with my proximity sensor on my X+ I grabbed an app called Rezound Proximity sensor adjust the PS1_CANC (Low_Threshold) value. My X+ is set to 95
hope this helps you.

When I make or receive calls, the screen acts perfectly as it should.
Goes dark when it's at my ear, the lights up when I pull it away from my ear, just the damn proximity light is on all the time draining my battery.
Anyway to turn it off?

nope, do you use the other sensors?
you can rename or nuke the following file, note that the rotation/prox/light sensors will be toasted after
adb shell
su
rm system/lib/hw/sensors.enrc2b.so
or to move it replace the rm to mv so do this mv system/lib/hw/sensors.enrc2b.so system/lib/hw/sensors.enrc2b.so.old

Phone display turns black with phone call ??

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 ??

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..
