I've had this issue since I got the device at popup in London on 21st July
The proximity sensor only seems to register if skin is actually pressing against the glass where the sensor sits which is bad because unless the top of my ear is in exactly the right place the screen stays on during calls meaning random key presses.
I'm thinking now this is a hardware issue, don't really want to RMA if I can help it.
Does anyone know any way to tweak the sensitivity of the sensor with a setting /line of code etc?
Mate, that does seem like a RMA.
I have no trouble with the proximity sensor. Works fine without touching the glass .
Know that's not what you want to hear but better to get it fixed now instead of investing a few days and still having to RMA....
Extra couple of days suffering and longer to wait return....

Hi all again,
I must saw I've NEVER had to do so many posting for a single phone... anyway.
I just updated my Leo to 1.61 via a tortuous goldcard process and the proximity sensor is still not working correctly My wife is the main user of the phone and I was watching her while on a call- the screen was on and off like some demented Xmas lights.
I have a theory regarding the problem. It's only my wife who has the problem with the phone, it's seems ok with me (but I don't use it as much!). The phone is very wide, and the proximity sensor is not central. I think that the sensor is missing her ear (she has small ears!). The gap between her ear lobe top and her head is too great for the sensor. I tested the sensor gap with my thumb and it seems to be around 1cm to activate.
The hardware solution is either move the sensor so it's central (that's not going to happen soon) OR increase the sensitivity of it.
Does anyone know how to change the sensitivity of the sensor OR anyway to completely disable the touch screen during a call.
Hmm I can not believe that, I've tested my sensor:
It put the lights out if i come closer that 1,5 cm next to the screen during a call. So it think this is not the source of your problem.
But: I'm running a 1.48 rom...
I had the proximity sensor behaving eratically upon installing a screen protector. Even though I installed the original HTC screen protector which has 2 holes to position exactly over the sensors but even then I had problems. Ever since removing the screen protector everything is okay again.
Just thought if your problem also coincides with installing a screen protector.
Regards
The problem occurs when your hair overlaps the proximity sensor, the light immediately comes on. Stick the phone back to the ear and the proximity sensor works perfectly on time.
p.s. ive long hair and I too faced this problem and figured it out by running a few test as mentioned above ;-)
Hope this helps.
well, I'm having the same problem and It's not caused because of my hair. it just sometimes works and sometimes doesn't. the test I make is using the palm of my hand. if during one call It's not working, it won't work no matter what you do. then if I make a call and its working, I can turn on and off the screen placing my hand in front of the sensor..

I reckon you clear the area around the receiver and try doing a hard reset.
CAUTION: Take an individual back of your data rather than doing a full backup using some software.
same problem
Hi, I have the same random proximity sensor bug problem. During call accidental hang-up happens every day. I have short hair and no screen protector. Is there any solution for this yet? thanks.
I wrote to HTC already, but they claim there is no problem reported. Sory for my English.
Had a similar problem. My proximity sensor is now working fine. Install the 'Proximity Sensor for Screen Off v0.2' cab. Search the forum for the thread.
thanks for tip, hope this little app will "evolve"...
hi,
i had the problem with the proximite, that it is only working when the phone is in portrait mode. when im incall and portrait i can put my finger to the sensor and it is working perfect. when i rotate the display to landscape the sensor does nothing and the display stays on. unfortunatly i turn the phone sometimes on the way to my ear, and so the screen stays on.
i will try now the mentoined .cab and see what it does for me.
regards mad
While im in a call on my G2 randomly the call will end or it will get muted or it will go on speaker phone. It seems like there is a proximity sensor or a light sensor in the upper left of the phone and randomly it freaks out mid call and turns on the screen and my cheek hits some of the touch buttons. It is very annoying. Randomly ill be in a conversation with my girlfriend and it will hang up -_-. maybe when we get root access or more api access to that sensor we can turn it down or something like that. Anyone else having a similar problem?

This is a common problem with smartphones that use proximity sensors. Whether or not you get this problem depends on how you hold your phone to your head and possibly whether you have long hair (there is some argument about that). Some phones also do have more problems than others, suggesting it might be related to programming of the proximity sensitivity/hysteresis.
I see. I actually do have long hair... that could be a factor. My hair could be moving across it or moving and it could be triggering the sensor. Maybe once we get root access we can see if there is a way to disable the sensor altogether for calls. I like the auto back light feature but so far in calls it is very annoying. Shouldn't be too hard i think.
One thing I like to do is cover the top part where the sensor is first with my ear / side of my head then place the rest of the phone on the side if my face. So angling it basically, whole process takes about 2 secs. Hope this helps.
fRom Snugs G2 ^.^
I have the same problem too, its annoying. What I do is that I try to keep the sensor area (top left of the phone) as close as possible to my case, also as covered as possible. Kepp the bottom half of the face a little bit away from the face (cheek). - this way you wont set off any on screen buttons if light does get through the sensor.
As the title said, is there?
Cause my DHD performs okay in call, it just that when im just using it normally it sometimes do this weird random clicking on the screen everywhere and lead to my phone unusable until i push power button and unlock again. I just discover that the culprit is the proximity sensor, so i covered it with black electrical tape and for full day i didnt encounter that weird bug again. Ive try to flash to custom roms and to such no luck its still there...
Your phone is faulty. Why don't you just get it replaced .
Just remove the tape and i tried blowing at the proximity sensor, and i think it works. My guess is that the hole in the ear piece is big enough that some dust got in and block the sensor. Im still trying it now and so far so good.
This has been happening pre and post Nodo on my focus. If i'm on a phone call for at least a few minutes, then pull the phone away from my head, the phone's display should become active, but it isn't.
Anyone else having this issue or is it time to exchange the phone?
I have the same issue also it seems like I have to press the power button a couple of times to get it back.
Sent from my SGH-i917 using XDA Windows Phone 7 App
I'm also having this issue. Anyone remember if ther were having it pre-Nodo? Just wondering if the update changed something.
Regardless, it's a bit of a PITA.
I experienced this after having to replace a cracked screen. I just recalibrated the proximity sensor with my finger about an inch away and it worked fine.

How did you do that?
Yeah, ditto that - how do recalibrate the sensor?
Samsung Diagnostic App.
http://forum.xda-developers.com/showthread.php?t=839154
I was pecking around the screens months ago, and there was one bank of tests (multi-touch, red, green, blue, white, battery, etc, etc) that allowed setting and viewing the proximity sensor.
I remember playing with moving my hand closer, and further and watching it change from sensed to clear.
Sorry, can't remember which codes now.
I used the Wiki:
http://forum.xda-developers.com/wiki/index.php?title=Samsung_Focus
LCD Test - *#0*#
Ok, mine says No Detection. Is there anyway to set the value?
One other thing to note, about the samsung focus specific update regarding disabling the touch sensitive buttons while in a program, that also isn't working for me either. Not sure if they are related, but thought I'd throw it out there.
And as far as calibrating goes, not sure it would help since the problem only occurs while I'm on a longer phone call. On short ones the proximity sensor works just fine.
If you move your finger closer to the sensor, it should eventually change to Detected. The "set" button at the bottom should set the proximity sensor to the new distance. Mine is around 75.

Mine says No Dectection. It has Prox Sensor: XXX I've taken my entire hand and covered my phone. NOTHING. When I push SET, It says ProxThreshold :0. Is there anyway to set it manually?
samsung focus post nodo
I believe the prox sensor issue is happening post nodo, I have never had this problem prior to the update... I have been able to fix it temporarily by pulling the battery and starting it up... don't know how long the fix works... got to do some testing... I am wondering if its a power thing as the screen wouldnt work when you plugged it in to power and had on a soft surface....
Still nothing. I didn't want to hard reset since I have Chevron installed. For some reason I did four updates on my phone and don't have a single backup. If I hard reset I'm S.O.L. with Twin Blades and other homebrew apps
What value does it show when you press the Reg button?
I've had issues with my earring tapping the screen while I talk and I had it fixed before NoDo, but the values reset when it was installed, they also appear to be different values now as my screen got supper finicky after the update. I was constantly hanging up or scrolling through multiple pages of stuff with my ear and you could see the screen turning on and off. I ran the proximity calibration while holding my hand in front and set to it to 1.
If it shows xx have you tried setting the value with nothing in front of the phone to see if it will at least zero out?

It has a big red box. It says No Detection. Prox Sensor:XXX Do I press Set or Reg?
another thing is wrong
seems like my light sensor is fried as well... I am starting to wonder if it's because of bad placement of the usb port... both lay right in front of the port, can't imagine pluging in and unpluging the phone would help if the sensors are right in front. I can't get either sensors to work anymore, even with a battery pull... does anyone else have this issue? goto the diagnosis menu and type
*#05#
you should be able to run through all the tests, I skip the feedback loop... Start at 1 and work your way through.
My Prox sensor says, no sensor XXX, and my light sensor is stuck with a value and will not change even when I cover the sensor... looks like a warranty replacement... how does this work with a sd card installed, the official WP7 ATT certified 8GB? Anyone else have to do this?

same problem here. seems like those two sensors are burned
I am currently running:
3.4.0 franco kernel
JOP40D - 4.2.1
And I have a really annoying bug on my nexus4 which I dont know if its just a fault on my phone or if its a setting that I have not configured.
Basically when I call someone the screen automatically switches off and there is no functionality, even when I press the power button the screen doesnt become active, which means I cant push keypad numbers when I am calling a number which has menu options, I cant hang up unless the other person does it first, and I cant put my phone on loudspeaker.
As soon as the call ends the screen becomes active again, Im sure that it has something to do with the camera sensor on the front of the phone because i know most of them detect when you are putting it up to your ear so then it turns off the touchscreen so that you dont acidentally touch the buttons with your face, with mine it just doesnt let you do anything at all when im in a call.
Would much appreciate any advice/help. Thanks in advance :good:
I believe you're referring to the proximity sensor. Do you have a screen protector with no cutout for the sensor or, perhaps, an incredibly oily face?
Agree with estallings15, I modified my screen protector and all has been well.
ahhhhhh right i have never thought to look into that, i assumed that the proximity sensor was just the camera which has a cutout on my screen protector but ive just realised that there is a small sensor on the left of the phone which I now assume is the proximity sensor.
OK i have just took my screen protector off and it works fine now! thanks for pointing that out
Maybe u guys could also help me with the other question that I posted on the q&a section lol :good:
much appreciated
