Mid Call Proximity Sensor Problem

Does anyone know if there is a way to adjust the proximity sensor.
It's proving a problem for my wife who uses the phone. When she's on a call the phone is intermittently sensing if she's holding it to her ear.
Hence being a capactive screen, when her cheek brushes the screen during a call the other end either hears DTMF or gets cut off by it touching the end call.
I called her yesterday and kept getting random DTMF digits sent to me, then I got sut off.
I was watching her use the phone and the screen was de-activiting (correctly going blank) for part of the call then coming back on, this would happen several times during one call.
Is this a hardware issue or software bug. Has anyone else suffered this problem?

Also happened to me a few times touching end call wih my cheek, really annoying.

Anyone else having the same problem with the proximity sensor intermittently not working during a call?

I had that problem on the old 1.43 ROM but it was fixed when I upgrade to 1.48.

I have this problem and I constantly have to call back and say sorry to my customers and blame it on the phone...
I have reported several errors to HTC and all i get back is "Take it to the retailer and get it changed, it must be a hw error", annoying as hell
1.48 not yet official in sweden.

TouchLockPro
You can try TouchLockPro, it has an InCallTweak, using the GSensor. Searching for accessing programmatically the Proximity Sensor though, for more options (e.g unlock by Proximity Sensor). It works on HTC Leo, people confirmed.

Thanks ZuinigeRijder.
I've tried the software and I think it might work.
I loaded the software and it worked without any further config I presume that is currect.

Indeed, TouchLockPro detects itself the available sensors and uses the available ones. Of course you can configure detailed things (via pressing the BattClock), but the defaults are already the sensible ones

Thanks again ZuinigeRijder.
Just been doing some more testing and occasionally the screen flashes on for a brief moment during a call. Could it be the proximity sensor trying to turn on the screen? Or is it the G sensor not being very accurate?
In the application is there a way for me to adjust the G-Sensor angles that activate the screen off? i.e. 45+ Degrees activate ??
Or are there any other adjustments I could make during testing??

I found one more problem... I checked it several times....
If u make a call using portrait orientation of phone app (Rotated using BSB Tweak). Proximity sensor doesnt work at all.... i made a while lyin on the bed and no matter wat i tried it wasnt turning off the screen....
Then i kept it in portrait position for a few seconds den proximity started working again...
Is there anyone who can confirm me with this problem.... or is this issue only with my HD2

1.61 is the proximity sensor bug fixed?

Hi,
Had the Leo since launch and it's driving me crazy with it's bugs.
Does anyone know if the following bugs have been fixed in 1.61?
1- Proximity Sensor intermittently not working correctly- I was on a call today and I cut the caller off 3 times.
2- SMS getting stuck in the Outbox.
I've already upgraded once to 1.48 I don't want to upgrade again until I know it's fixed.
I should learn in the future not to buy Version 1 of a product. The leo (HTC HD2) feels more like beta (field trial) 0.8 software.

Well, agree to some extent on the "field trial" feeling...
However, I never had the proximity sensor problem, and since I installed 1.61, the SMS issue did not come back (had it rarely before, though).
Personally, the much better radio which comes with this update is worth the flashing alone... but that´s my personal opinion...

Have you got a screen protector on the leo?
when I use mine, the proximity doesnt work fine and I neet to cut the plastic of the protector of that zone

The proximity sensor also doesn't work with hair. Do you have long hair that covers your ears?
I noticed this when my girlfriend used my phone, the screen just wouldn't go off.

I use 1.48 rom and very strangely i have proximty sensor problems when calling numbers that are not on my carrier network ... don.t whant to report it as a bug but ... strange. Even so, have you tried to disable phone canvas cover? Seems it doesn.t switch on so often when this is disabled (using BSB Tweaks)

well my experience with proximity sensor:
when i just make a call it works fine.
when i use the keypad after making a call (for entering extensions and stuff) the proximity sensor stops working. it happens every single time I use the keypad while in a call. I will soon report this bug to HTC.
I don't have any screen protectors on.

just been testing that, I can't replicate it at all.
start a call, press keypad, enter some digits close keypad, or don't close keypad, proximity sensor works fine.
on 161

I have some strange bug with calling screen.
When I call to somebody and talk more then 5-10 min, then I can't press Disconnect red button.
But sometimes, if I call and don't hold phone near of head, for headset for example, I haven't any problem with screen, all buttons pressed normally.
Very strange behavior.

for me - proximity sensor not working correctly in 1.61 (like in 1.48 too)

Had exactly the same issue with 1.43, didn't notice it *yet* on 1.48. Screen wouldn't dim after entering dtmf.

Interestingly it's my wife who uses the phone and she has long hair- that fits in with the previous posting
Why does the proximity sensor not work with long hair!!! She still has the phone close to her ear. I can watch her during a call and the screen lights up and activates on and off. I'm not too sure if there are two bugs here- one is radio cutoff, and the other a proximity sensor issue.
I called her a few times over the last day- and cut offs are quite regular.
Previously I used to get various DTMF digits sent down the line as well from her cheek touching the screen, but not now.
I'll give this phone a few more weeks before it get sent back.
FYI- I do not use a screen protector.

With regards to the proximity sensor... I'm on the LEO with a WWE 1.48 rom (experienced the same thing with the original 1.43). Like you all say, it is still a bit flaky at best, though did improve with 1.48. However I find myself doing a little work around...
(to note: I do have the official screen protector attached on as well - it has 2 little holes for the sensors in the film)
• Make or receive a call
• Drop the “virtual” guard
• Enable loud speaker mode / Disable loud speaker mode
• Talk/Listen to your call
Hey presto... you should find the proximity sensor working again. (Got it down to a fine art... the other end doesn’t even realise)

Me too ! Im on 1.43 WWE ROM

i upgraded 1.61 and noticed the proximity bug once yesterday
the only time it happend was when I was ON a call and had another one coming in (call waiting) ... so once i switched over to the other caller, my proximity sensor stopped working
No idea why...but i tried it again 10 minutes later and it worked.
So its intermittent...pretty annoying though
I hope HTC is aware of the problem

I think not... Its getting really annoying

Do you thing the original screen protector from HTC make all the problems with the proxi,ity sensor?
I have the same problem with this sensor, I am not sure which hole the is proximity semsor?

thake the screen protector out or cut it and the proximity sensor will work perfect

[Q] End call screen freeze - solution?

I keep having this problem with almost every build I try in my TMO HD2. When holding the phone, as soon as I make a call, the screen goes black. When I end the call using the hardware button, the keypad lights come on and the screen is non responsive until I plug in the charger. Solution?

I too have this problem but not that bad.After ending the call the screen stays black for 3-4 seconds, but it is still irritating.

Well mine stays black until I insert the charger which renders any of the builds with the issue completley unusable.

this is already known problem, especialy with DesireHD build it gets worst. there is no solution yet, as I understood, but several workarounds, for example discussed in this thread
http://forum.xda-developers.com/showthread.php?t=835127

I always say it but maybe trying a different build would work?

Do you have BsB Tweaks installed? If so, this problem is caused by having the "Tap Time" tweak set to "on". I was having this issue and read about the fix somewhere (might have been here). I set "Tap Time" to "off" and.... immediate and permanent (so far, about a week) fix.

EndCall - black screen freez
same problem here... please help me !
i had installed on my hd2 DL.Desire.v4.31.44.12 and it's worked fine for a wile but now i tryed the last version of dl desire and a gingerbread build but the problem didn't disapear. I reinstalled radio that is version 2.15.50.14 but .. nothing seams to work
I need your help guys !
Sorry for my bad english.
I was curious to see if in wmo it is the same problem, but no... in wmo works fine.
it's strange that at first fresh install of dl.desire everything was ok, but now it isn't. I've reinstalled magldr but with the same results.
It doesen't work.
I think it is something with the proximity sensor, because when i turn on the speaker and the screen is on i can end the call with no problem and no freeze.
the only solution i have for now to unfreeze the screen is to plug in the charger cable in the device.

Problem Solved
I just cleaned the proximity sensor and it's working great. No freeze no black screen.

I have the same problem.

If you have the original screen protector with the 2 holes from htc, try to clean the sensors with a soft microfiber.
I didn't had this problem untill i replaced my screen protector with the htc screen protector. (the 2 little holes are exposed to dust and dirt, and when you remove the phone from your ear the sensor doesn't respond because of dirt. I think in android the voltage for sensors is a little bit lower than wmo, and that makes the sensor less responsive)
Sorry for my english.

install from android market ADW launcher....make it default home screen...try this one too..

Solution
Everything difficult-is easier)
Just clean dust on the sreen,where sensor is situated.

[Q] Disable Proximity Sensor

Hi,
is there an option for android-HD2s to disable the proximity sensor? I'm sick of the behavior of my device that the screen doesn't turn on again after making a phone call, taking out battery isn't a very useful option...
I already tried the Recalibrator for the sensor (originally for DesireHD), it worked for a few days but now again i've got the problem...
Therefore i'd rather have the screen turned on during the phone call, than having a blocked phone after the call..,
Do you know a solution?

hi, I guess you are using Desire HD rom. If is so I fully understand you. Those build s avery big and laggy. After trying many,many rom s Iwent to this one>http://forum.xda-developers.com/showthread.php?t=931126
The screen turns on , everything work s fine. And it is crazy fast. Believe me, you will love android after this.

the best DHD Rom is Core Droid, in 1.3 the sensor was good, but in the actual 1.4 its bad again, try it when the next version is out. its very fast and nice skinned, also always good updates like the controls widget in the notifications bar.

Are we talking about the rom for hd2??is there anyone who can help us on the same problem?

I do this that way http://forum.xda-developers.com/showpost.php?p=16008095&postcount=4

No Wake-up after phone call

Still tested different NAND-Android Roms on my HD2 but got still a problem. If i make a phone call and the screen turns black while calling i press the endkey to end the phone call. But instead of turning on the device, the screen stays black and i need to pull the battery and restart the phone.
If i make a phone call and use the free speaking funktion, while the screen don't turn off, i got no problem when ending the phone call.
I don't know what the problem could be, but it seems, that the thing has to do with the sensor who turns the screen on and off. But i don't know if this is the problem and/or know how to fix this problem. Like i said, i tested different Android Roms formated the SD-Card, deleted cache and all the stuff, but nothing fixed this problem. :-(

28 Views and no one with this problem? :-(

There are 2 other threads discussing this issue already. Here is one.
http://forum.xda-developers.com/showthread.php?t=946012
Issue lies with the light/proximity sensor. Could be defective hardware. Could be incorrect sensor drivers. Could be dirty sensors. I have yet to take mine apart to check for dirt on sensors. Blowing into the led/earpiece opening seemed to help. I notice if it doesn't come back on I can hold a very bright light (ex: cigarette lighter) about an inch away and the screen comes on as long as the lighter is lit. Sometimes it stays on.

thanks for your answer. seems to be more things to test and maybe solve this problem. Thanks!

THANK YOU Agoattamer!
Your link helped me to solve the problem! I just cutted a little piece of my screen protector, where the proximity sensor is, and got no more freezes after the phone calls! The screen protector still got two holes for the light and proximity sensor, but this seemed not to be big enough. Anyway, thank you a lot for your post!

I also tried a a lot of different NAND ROM and I had also this problem and I can't use Android efficiently. Now I am using hyperdroid ROM ( first GBX now CM). With this ROM and sanity app (from market, with correct settings you can find with trying) I almost solve this problem. ( probability of 95 % I don't get this error)

hey guys! i found the solution goin through the market!
download an app called "Sanity" theres a free version in the regular android market.
go to the settings > general > check "Reverse Proximity" (This will give you some warning about not using it if you DONT have a buggy proximity sensor). Check it anyways. Then go back to preferences then click "Proximity" scroll down and uncheck Turn off screen and leave leave the Turn on screen checked. this will force your phone to stay on during calls so that it never has to go through the proximity phase of calls this no more black screens. Hope this was helpful ^_^
