Proximity Issues - Verizon Samsung Galaxy S 4

I believe my proximity sensor is broken. I cannot use the screen during a call, it stays black the entire time regardless of what buttons I press. After a call ends the screen will stay black and I have to battery pull to turn the screen back on. How can I disable this sensor??

All you have to do is get a can of compressed air and blow into the earpiece to get dust out of the sensor every time this happens. It seems to be a relatively common problem.

I thought mine was broken too until I did this. Sprayed air in the ear piece for about 5 seconds and now it works again.

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.

Nope I have nothing on the screen its as it came
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"

I asked my local dealer, i will receive a new device tomorrow.

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 :-(

What was the outcome. Did the lights turn off?

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...

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] In-call screen blackout issue. Help please!

I'm hoping someone has a solution to this very annoying issue I'm having with my Note 2.
It's Verizon - stock - 4.1.2
When I dial a phone number and put the phone to my ear the screen goes black - as it should. But when I move the phone away from my ear the screen doesn't come back on. It stays blacked out and I can't get it to come back on with the home or even the power button.
This means I can't hang up, I can't put the phone on speakerphone mode, I can't use the touchtone pad to navigate through menus. It's made my phone a real pain in the arse.
Anyone have any thoughts on what to do or what's going wrong?:fingers-crossed:
A couple things I'm thinking... Try pulling out your spen when it happens.. Do a battery pull if nothing else.. It might be the proximity censor... Do you have a screen protector on it?

I'll try the s-pen, maybe that will work.
I've got a screen protector, but it's the same one I've had on since I first bought the phone months ago. I've pulled the battery several time, it's the only way to hang up!
I too think it's the proximity censor, which sucks because I don't want to trade in my phone for some refurb that's gone through God knows what.
Good luck...those were the only things I could think of. ..

Check your case and your screen protector. and clean the proximity sensor. Know it sounds weird, but have problems before with screen protectors getting oil on them when placed to the ear and the sensor thinking you are still close. Also lighting from cases makes the sensor go fruity. Not a science but worth a check.

THANKS! I used the compressed air method - I blew it through the ear hole and open the back of the phone and blew it through any openings I saw. Now the sensor works perfectly again. :highfive::highfive:

Does anyone have issues with proximity sensor during calls?

Never noticed this on any other phone before but when I'm on a call, the screen sometimes fails to turn off and I end up activating the notification panel with my fat face and accidentally toggling different settings.
Phone bought from HK and running. 475 without any modifications. Any help greatly appreciated.

i have the same problem too but mine is a little bit different. my proximity sensor is always on. once i answer a call my screen automatically turns off and i have too wait for the caller to hang up before my screen turns on back
Ok I figured out what was happening in my situation. The phone is so big I didn't know where to hold it next to my ear. After a bit of experimenting, I've now found the optimal position.
A bit silly but I'd thought I'd share my stupidity in case someone out there is like me.

This is normally caused by a screen protector covering the proximity sensor try to remove the protector and try again.

Screen issues during call connect

My power button broke on my phone and so I purchased what was described as a "pulled from working phone" circuit board with power ribbon. Now when a call connects my screen automatically turns off. Depending on which ROM I either can do nothing until the call disconnects or I can press the power button and the screen turns on.
Anybody have any ideas on how to stop the madness. It is quite frustrating.
It sounds like a proximity sensor issue. It would be up there next to the power cable ribbon. Can you check to see if it isn't being obstructed or loose?

It is more of a software issue. I was using CM12 and when a call connected the screen would turn off and would not come back on until the call disconnected and if the screen was off and a call came in the screen would not turn on and you could not make it come on. I am now using Sense Six from Santod. Screen still turns off when a call connects but the power turns it back on and with an incoming call the screen actually turns on. Thank you for posting though.

When the sensor recognizes "near" it will have the screen shut off during a call. That is why I suggest it is the sensor. Also you having the issue after you dealing with hardware near the sensor seems it is more than likely hardware than software.
Hitting the power button on some roms will turn the screen on and override the "near/far" of the sensor. Do a search for "rezound proximity sensor calibrator" on Google Play. Check to see if you are getting near/far correctly.
Edit: https://play.google.com/store/apps/details?id=com.incredicontrol.ProxSensorCalibrator just checked and it does show near/far for my phone correctly. This app works for pretty much all HTC phones to calibrate the prox sensor.

Well... I certainly stand corrected... Thank you very much. Now if I could get it right. It started out as 68 and I think like 12 and I have had to crank it down to 41 for my screen to not turn off when the call connects but then it does not cut off when putting the phone to my head. Why would this happen... Is my phone just old?

You would have to play with the settings. Best bet would be putting your finger over the sensor while in the app and scale it until you see near, then put finger away and see if it shows far. Be sure to check the option to "set on boot" when you get it perfect.

I am not sure this thing is working right. It never changes what it says. It always says Near and doesn't matter which I change while I put my thumb over the sensor. That is wrong... Right???

Yes, that is right, something is going on. You could have something covering the sensor when you put the power button ribbon in. At least we have checked and see the issue is most likely hardware. It has been awhile since I took my DNA apart, and can't again as it got lost in the mail, so I cannot check to see if the ribbon goes by the sensor.

Screen times out when on speakerphone

Am I missing a setting to shut this feature off?
It's extremely annoying that the screen goes off while talking on speakerphone.
My Note 5 never did this.

Do you have a screen protector on and does it cover the proximity sensor? Or are you describing that went on speakers phone at some point the screen times out? Like 30 seconds for example.

No screen protector.
No case on the device.
Screen timeout is set for 10 minutes.
When using speakerphone screen shuts off after 30 seconds.
