Proximity sensor problems!

Hi guys,
I dont know if this has already been discussed or if anybody has had the same problem,
The proximity sensor that is supposed to turn off the display while in call only works when i make a call. If i am receiving a call then the display stays on and i end up ending the call accidently will my cheek.
I was wondering if there is a fix or app to sort this out. I am looking for something that purely sorts this problem out and dont really want any other features etc.
Many thanks,
Loz

I cannot replicate this problem. The sensor on my HD2 works perfectly on incoming calls.

no offences but i am sort of hoping others have this problem so im not the only one lol strength in numbers and all that...
can anyone relate to the problem i have, i have searched the settings time amd time again looking for proximity settings to see if it has been disable or something
please help!

hi guys,
i am still having problems with the proximity sensor when i receive a call, can anyone help????????
thanks

There has been a few posts like this in the past, but AFAIK no-one has posted a solution or reason for it happening. I've never had any problems with the proximity sensor on my handset so can't help any either, but I would guess it has something to do with using a screen-protector or possibly the screen being full of smudges right around the sensor.

thanks for the reply
i dont think it is the screen protector im using because it works whenever i make a call, its just when receiving a call it doesnt turn off the display!
does anyone no if there is a fix or reg edit i could do to get it working again?????

Hello,
I have the same bug and I post it yesterday, the screen off when I make a call and stay on when I am getting a call.
My Rom is 1.48.405 from UK, and I have screen protection from HTC with small hole on the sensors.
also when I making a call the screen off but need to turn on when you take the phone far from your head, sometimes it is heppens but sometimes not.
kochavy

When I bought the phone it was 1.43.405 and I upgraded it to 1.48.405.
maybe this is the problem!!
kochavy

just a innocent fact.
I had noticed that when starting to make a phone call the prox. sensor turns off the display but when the connection is made (the fuzzy noise and the first beep) the displays turns on. To reactivate the prox. sens i have to move the phone from my ear and then approach it again (please forgive my bad english) and the display turn off as designed. This issue can lead to the idea that the sensor is broken or malfunction.
I hope it helped

when i make a call the screen turns off straight the way before i have even put the phone to my ear, and to turn the display on i have to press a hard key
i am startin to think it is a proxomity sensor malfunction so hoping for some kind of fix

i dont no it does it automatically but not using the prox sensor, i usually press the back key to turn it back on but the it stays on
there is nothin i can do when i get a call the display always stays on
HTC havent got back to me so i was hoing some one on here would no wat to do!
may someone can help us out?

I will wait for Rom 1.66

yeah me too hopefully that will resolve our problem
ill be checking htc website constantly until the uk rom is released

After two weeks testing I found out that the original screen protector with the two holes for the sensor makes the problems!!!
thake the screen protector out or cut it and the proximity sensor will work perfect.

Screen not going off in a call!!!

Hy all
I have a strange problem with my X10! The will not go off in a call! (or at least most of the times it won't) The sensors should turn the screen off while the phone is to to my ear but most of the time it will not!
There is a hidden menu that have tests for almost every hardware component but the test for the proximity sensor only shows that the sensor is OFF and won't do the test!
Ideas?

The sensor is the little black circle (sort of) above and to the left of the "n"
e.g. Sony Ericsso'n'
Have you tried putting your finger over it during the test?

same problem here i tried the finger-trick doesnt work

I tried it and the test shows ON while my finger is there! So the sensor works properly but why the dialer is not using it to control the screen?

As stated before, if you cover the 'hole', the screen would not react to any of your finger touches. The screen would still be on but would turn off according to your settings (like 30 seconds or 1 minute or whichever). Try it. Call someone, cover the hole and try to hit 'end call' or slide up the keypad and then cover the hole and try to hit numbers.

The purpose of the proximity sensor is to turn the screen off in a call while the phone is to your ear! if i cover the sensor it must turn the screen off! but it doesn't! There is some kind of timeout set to this! The screen will turn off but after some time! this makes the proximity sensor almost useless!

No, it is to disable touchscreen buttons. It will turn off when time you've selected is over and turn on again and enable touch buttons when you take the phone out from your face.
Though i think you're right, it should turn the screen off to save battery, it is silly to have the screen on when you are using it.

Quite right!
I guess the expectations are again set by Apple's standards. Their proximity sensor functions as one would expect.
However the sensor on the X10 does what it was designed to do, and that's to deactivate the touchpad whilst the device is held up to your ear.
The screen timeout is a different setting all together (unfortunately).

Not the expectation set by Apple. It's expectation for any right minded individual.
SE software is just well known as one of the worst top players in the industry.
FFS, they spent all the time on DRM, lock the phone, developing battery hungry useless software on 1.6 rather than push out 2.1 asap, that tells you something.

Why not go through the Manual once before abusing Company left - right.....
Let me copy and paste it for you guys........
Sensors
Your phone has two built-in sensors – a light sensor and a proximity sensor. The light sensor is used for automatic LCD backlight control. The proximity sensor turns the touch screen off when your face touches the screen. This prevents you from unintentionally activating phone functions when you are engaged in a call.

Yes and this is plain stupid use of the sensor! Take the HD2 for instance! Its proximity sensor turns the screen off the second you take the phone to your ear! This is done with every HTC device having the sensor! It is just misused on the X10! I hope that somebody here would correct this with a little program some day!

This is the main problem with us ,,, we start to compare and complain rather than think why did SE will give two sensors instead of one.
Answer is not known to me but this much I know they know better than us.
If you think you know better, be my guest and throw some knowledge here. I am new to Android but not to SE.

So im new to the forums, but I was having a problem with the proximity sensor...
As stated in a lot of threads, the proximity sensor does work and will "lock" the screen so that once your face is near the screen it will not allow any clicking of the buttons.
Also the screen is supposed to turn off about 15sec into the call. Mine turned off, but then all of a sudden turned on again...this would happen repeatedly.
I found out the solution...it seems advance task killer was not allowing the screen to turn off.
I had auto kill enabled and set it to when the phone was locked to kill apps.
I turned off auto kill, and everything seems to be working fine with the screen and proximity sensor now..
hope this helps anyone having this issue!

thx, same problem here !!

so its pretty clear none of us know the answer to this, but yet we're still bashing each other. LOL! ppl let's get constructive, we dont have the answers so lets accept the fact and seek help some where else.

o2 Germany told me, that Sony Ericsson will bring us an update within the next 4 weeks to all devices.
It will be an update with alot of bug fixes (e.g. proximity sensor ) and speed improvements.
So, be cool. Sony Ericsson is working on that and with Eclair in autumn, our battery will perform very well.

Proximity sensor problem! [SOLVED!]

Hi everyone, welcome to the next thread of mine where I would like to share with you an interesting case of a'faulty' proximity sensor. The issue with the sensor started a few weeks ago (I own my defy for a few months) and the problem I had with it was that sometimes during I was making a call the screen was not being turned off, and more whats more annoying - the screen was never turned on again after finishing the call.
I do not have a screen protector and the screen glass is original.
I downloaded an application that showed the state of the sensor and after a many examinations i found out that many times the sensor does not distinguish between the states of being covered and uncovered.
I tried everything - factory reset, clean installations, different ROMs - nothing helped. The only thing that helped a little was a tweak availale in the CM7 ROM by Quarx (not available in the STABLE CM7 though!) in the screen settings menu -which forced the screen to be turned on after finihing a call, and I could also set the power button to end a call in the accessibility options. So this helped but did not solve my problem.
Fortunately, after many questions asked on so many threads, the user monecafe PMed me with a link to a video where its clrealy shown what is the problem and how easy it is to fix it!
without sayng more - here is the solution for anybody experiencing this issue:
http://youtu.be/uMk1S90MjbY
I hope this helps !
& a BIG THANK YOU to monecafe who sent me this video

this is great, very simple solution but...
how will that affect the water resistant feature of our defys?

try turning off auto-brightness
posting to say... try turning off auto-brightness (worked for me)

I used to have this problem. Stable CM7.2 solves this issue for me. I used to get the screen to turn on before by just rubbing the area with the proximity sensor with my thumb as if it was dirty.

i still have this problem. , after the Waterproof failed with my phone ( i dont leave it in water, i just wash it !! the proximity sensor failed too when i make a call screen is black cant see anything..so my question is if i change the screen touch proximity sensor work?? or its on the board ? where is the proximity sensor place?..how can i solve this problem by myself.
i saw the video but not solve the problem..
i back to stock ROM _there_ if i press power button the screen back but in coustoms ROMs the screen off not back till remove the battery!! any software make screen on at call and disible the proximity sensor ?
thank you inadvance

CAN I GET THE TECHNICAL GUIDE(MAP) OF BOARD?

I also have problems with proximity sensor. With pressure on the screen where the sensor is located it is working again.
So I can believe that changing the screw pressure might solve the problem. But what is the initial reason for this? It is not a pressure sensor!

Hello All, I've been using the proximity sensor app on my DHD for quite some time now... LOVE IT ! However, now when I open the app & tap on Start & cover the proximity sensor on the phone, there is NO RESPONSE... Meaning the msg stays FAR... It DOES NOT change to NEAR.... Can anyone help me out ? CHEERS !

Found a possible Solution suggested by a supplier on Amazon;Switch off the phone - Hold power button & volume down button
simultaneously to bootinto factory testmode - use volume swith toscroll thru to 'test report' - select with the home key - scroll down to 'PS calibration' - select it then scroll to 'do calibration' let it do the calibration till it gives OK.Go back to 1st menu & reboot.
Was only partially successful forme, it may work for you.

Is this applicable for Motorola Defy or for the Chinese clone?
I tried this on my Defy running JB 4.1.2. I cannot get into the "factory testmode" even after pressing the VOL down key at boot up.
I just get a screen with an exclamation and the android bot.
Nothing happens after that.
BTW: What size of screw driver should I use to perform the trick in the video posted by the OP.

Not applicable to original defy

Screen turns black during call, but then won't turn back on?

On my AT&T Galaxy S4, when I make a call the screen goes black when my face is next to the phone. This is good.
However, when I take my face away the screen will NOT turn back on. If I hit the [Power] or [Home] buttons, it will sometimes turn back on, but often times it requires several presses or requires me to wait several seconds until the phone turns back on.
I've tested this on stock and several ROMs...
Does anybody else have this problem?
If so, how do I fix it?

Pick up a can of compressed air and blow in the earphone. Sure enough the proximity sensor works perfectly now. I have solved this problem doing this. Tell me something

You can test your proximity sensor readings here. It should turn the screen green and vibrate the phone constantly while your hand is in proximity. You can also see the numerical readings. The sensor works to about 6 inches.
If its not acting right, then you need to use faux kernel or you have a hardware failure.
If it is acting right, then use a better rom.

I seem to be having this issue on stock rom. When I bring my hand close to the sensor in diagnostic mode it goes green...but it doesn't stop when I remove my hand and there's nothing nearby. This seems to mirror the experience...where the phone goes black during a call, but doesn't wake up when it's removed.

Yes, exactly!
I've flashed back to stock and tried that test screen. The sensor is OK at first, then I move my hand over it and it turns green and stays that way even after I remove my hand.
It seems like the sensor is half-working but gets stuck in the "on" position...

that sucks. i guess its time to contact samsung about warranty. just make sure theres no dirt on the sensor or anything

This is exactly what I done only I used a straw and I blew down it like hell and it cleared the problem. My phone was due to be returned to be fixed under warranty today but I tried a last ditch attempt and with the straw and blowing down it into the earpiece (aimed slightly towards the proximity sensor) I managed to sort the problem. It seems a little dirt or dust gets on the sensor and makes it malfunction.
Give it a whirl to see if it will work

[Q] Screen goes black when I make a call

My nexus 4 Lollipop 5.1 Seems to have a problem when I make a call. I hit the phone symbol, select the number I want to call from my requent call list. I hit the dial button and make the call........ The problem comes when I go to end the call the screen goes black such that I can end the call. I just have a black screen........
Does anyone out there have any idea whats happening and what the fix may be?
Thanks for any help

Remove your screen protector.

The screen is supposed to go black when you make a call--or, rather, when you place the phone to your ear. There is a "proximity detector" along the top edge of the screen, and it detects your ear when your ear gets close. The phone then turns off the screen sensors so that your ear or your cheek doesn't push any buttons while you are talking, and turns off the screen illumination for aesthetic reasons. However, the proximity detector is supposed to cause the screen to turn back on when you remove the phone from your ear. That isn't happening for you. When it didn't happen for me, I took it to the shop. The tech said the proximity detector was broken, and ordered a new one. But replacing the proximity detector didn't help. He finally disabled the sensor so that proximity was never detected. that worked.
This story does not have a happy ending for me. The phone worked for a couple of days. Then I tried to reboot, and it went in to a boot loop. None of the standard cures for a boot loop is helping me. I doubt if the two problems are connected.

Proximity sensor turns off screen when you put it to your ear to avoid your skin touching the "End call" button or something else

Ok, was worth a shot...
Then you must likely have a faulty proximity sensor, as stated previously.
Download an app, like AndroSensor, and see what the output for the proximity sensor reads. When nothing is covering the sensor (top left corner) it should read 5 cm/2 inch, or something similar. If it reads 0, it's busted...

Hmm... The plot thickens...
That means you have a working proximity sensor. No idea what it could be then.

I have the same issue. In my case, the proximity sensor may have been broken or blocked by dust.
My "temporary" solution is using the power button to disconnect calls. While using a Bluetooth headset, the screen can be turned on. I hope there is a better solution.
