Proximity sensor in Touch HD

I recently read on gsmarena that the touch hd has a proximity sensor for auto turn off.
is this true?
if yes, could we use this sensor to automatically answer a call for example
maybe we can add to the sensory sdk of koushi a class for the proximity sensor.
just a thought

I'm guessing that the "proximity" sensor that has been discussed is actually the light sensor beside the earpiece. This can be used to turn the backlight off when applied to your ear during a call. using this as a means to asnwer a call would not be reliable, and what would happen if the phone is in your pocket etc etc.

i think is just like the iphone when u place it next to ear the it goes off to save battery ?

It doesn't work like the iPhone.
The HD, like all the devices using a Qualcomm chip, is just switching off the screen when a call starts, the phone next to the ear or not. It just doesn't use the light sensor at all during a call.
I asked for a soft that permit the use of the light and G sensor during a call to switch off/on the screen. You'll find more info here : http://forum.xda-developers.com/showthread.php?t=451456

I'm looking for this.. If you find a solution send me a PM, I will do the same

Proximty and resume
The proximty sensor will turn off the screen when places the phone next to your ear. I guess this help to prevent accidental touch on buttons. However, I have a problem with my new Touch Pro2:
When the phone is placed away from your ear, the screen will go back to home instead of previous phone dial pad. When I listen to my voice mail or join a conference, a lot of navigation is needed in order to dial the command buttons.(press a 7 for next, or # for ....)
Any chance to make the screen resume at previous location? My first improvement suggestion to HTC.

Concerning this sensor, funny I thought it was some myth as mine never seemed to work or only half assed. Then after flashing many diff roms and settling on the "energy" Rom I see that much to my pleasent surprise it works perfect, just as intended. This is a fantastic feature and my first device it has actually functioned properly on.

hi
yeh there is a setting somewhere that lets you go straight to home when you turn the device on instead of loading the screen it was already on.
its set to default but you can change it.
i forgot what the app was called though, i think it was possibly an option in hd tweak or something

THERE IS NO proximity sensor in touch hd

However I've been told that "Touch Incall Screen Tweak" does beautifully on the HD and probably it's what you´re asking.

From what I've been reading spec wise I believe your correct, but I cannot explain then why when I make a call with the HD up to my ear the screen goes dark then when I pull it away to input a number from the kp it lights up. Is it the light sensor then? I'll check in the NRG energy ROM forum and search for some info as I'm running his ROM. I love this feature btw and have not noticed it in any other ROM I've tried.

Thanks for the response. Works a treat.

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

Proximity Sensor Problem 1.61 :-( Is this the issue?

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

troubles with proximity sensor

hi all,
i have Some problem with the proximity sensor.
when i lanch a call, first i put the phone near My head, the phone goes black,
but 2 seconds after, when It start tonning (ringing in the speaker) the phone wake up.
if i put It off and back It goes off.
but when the person answer, It's the same thing, the phone wake up. and i must put It off the head and back.
if i dont do this i cut All people 3 or 4 times.
if i receive a call, no problem.
i know some people have already post same problem with proximity sensor, but nobody explain it.
if someone can help me to fix it.
(sorry for my English )

im sorry but I really need help

Hi ! I`m so sorry but I cant help you. The proximity sensor did act strange on me with no obvious reason and I was forced to hard reset ...
Cordialement ,
Sergiu

Even if i hard reset, there is no change.
If i call someone, on each step the phone switch on :
when start ringing ... and after when the person answer ...
is there a registry to edit, or maybe a ROM update ?? im in 1.43
But if i update the ROM i'll loose my orange tv player app

You may try to flash another ROM at your choice ...

I know this might sound a strange question, but do you have long hair?
I only ask as this issue has been raised by a few other people, and most of them have said it either happens with their girlfriends (who have long hair), or that they have long hair.
I have short hair and I literally couldn't be more impressed with the proximity sensor.

lol, no ...
i' ve short hair.
i tried with the finger hidding the proximity sensor, and i can see when the phone start ringing it wake up, and the same thing when the person answer, or answering machin.
so it's a software problem.
i tried to update the ROM, and it says it can't update
maybe because i'm on French Orange ROM .
i'm sure if i can update with RUU rom, it will work fine after

I have this problem occasionally. It seems the proximity sensor somehow cooperates with G-sensor, because last time I had this problem I was lying in bed while calling, and screen simply did not turn of. But when I turned the phone vertically, and back, it started to work. Very strange.

so i upload the ROM to an officialy 1.48 (i have no orange rom and app now)
but still the same problem.
the phone goes black, but wake up when start ringing, and same when the person answer the call
i need help, because each time i cut always the call if my hear touch "end call".
now to keep the call i put it back from my head and back to when start ringing, and i do the same 5 seconds later when the person answer.
and after its ok, the phone stay off
i love this phone, but i'm sad

I guess it's a bug HTC will have to fix at some time. I've read it can happen to all ROMs.
But for the meantime, there's a workaround. You can install S2U2, it's a nice program. and one of its features allows you to choose "blank screen on talk". Never fails. Try it. No more accidental button clicks.

Thx a lot i'll try it (try to find it before )
maybe someone can make a soft to have a slide to unlock while calling ??!!
but i'll try your soft and tell you

same problem with my hd2....despite I tryied several rom on several build.
just a hint: don't activate "sms wakeup" (BSB allows that), because if u receive a message during a call, display will activate again!
It's a big issue, coz I cut many calls or I push buttons during a call...
I need a cab to lock the screen during a call!

ok i try S2U2, but difficult to configure...
always the same thing.
i found that not all numbers bug !!
i try a friends and all is ok, but my wife or my mother or others it bug
i dont know why some work and other not
i some one can help me trying configure S2U2 ???
or a cab just maybe to slide unlock while calling, something like that.
are we only 2 with that bug ????

it's not about the number u call, it's about simple casistic! try to recall the same number once the black screen doesn't work...try and it's gonna work! it's how sensor application works....just when it wants!
everythin was right with the resistive screen, but the capacitive one needs to a different lock.

i test sevral times on the sames numbers.
always my friend number 1 work nice, and all others not
it's very strange !

after call, press windows key and then lock pad.... I am doing this now cause of occasional problems....

yep, its a way...
but it's so strange.
i see when i try to call a home phone all is ok.
and some operators just bug the proximity sensor !!??!!??
So strange.
i just try another rom (an english one) but the same thing
and i have some trouble to make a god configuration for S2U2
so still no solutions... thats too bad

Hi all,
I come back to you to explain the situation now.
I call the orange center for smartphone, and i explain my troubles, it was last thursday.
So they change my phone last friday.
I tried directly, and exactly the same problem.
i called them again, and explain again, then they change it an other time.
This morning they come change it for the 2nd time, i try directly again,
then the same thing. alwayes the same problem.
so i call them again, and they say someone call me in this week to talk about the trouble.
i try other orange sim card, and same problem.
so in all my contact list, i've only 2 numbers which there is no trouble.
For all others numbers, the phone wake up each time.
PS : the orange service has nobody instead of me who have this trouble
anyone have a solution ????

proximity problems
Hi,
i also have the proximity sensor problem (or rather wife has)
HTC HD2 on UK o2 operator ROM
as i said, wife has a problem of screen activating during calls, it has not happened to me yet ?
noticed she always holds the phone to her left ear (wont change sides she says), i hold it to the right ear !
really need a fix for this as she threw it at me tonight as she cut off a really important call ! !

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.

Unintended taps during call: how to prevent them?

Hi!
I"m not the only having the problem: during a call unintended taps takes place while screen waking up is not registered during the call. So, you see, I'm not sure a proximity sensor is the reason of the problem as far as screen is kept turned off.
I have tried to reproduce the issue by fingers, but wasn't lucky.
Have you any ideas how to eliminate the problem?
I mean not-rooted official up-to-date stock firmware use case.
And, by the way, I haven't found proximity sensor calibration in service menu for A1. Is it placed somewhere into another place?

That happens to me all the time too.

Yup, me too. While in call I sometimes unknowingly turn on the flashlight and probably look like an idiot. ?

With the rn3p I would constantly end up muted. With mi a1 the problem is much less although I've noticed that numbers are still pressed. I've learned over time to switch to keypad so when something gets touched it's not the mute and at worst the other person receives some key tones.

I also have this problem a lot. I mute myself 9/10. To bypass to problem, I just lock the screen before placing it against my ear.

Yes, a simple soutions is just when you call someone, imidiately press power button to lock the screen (no password or fingerprint requred to unlock)

That's what I've been doing. That and pushing the top part of the mobile on my face just to make sure. lol
Oh and use the Feedback app and send it to xiaomi and hope they fix it on the next update.

i had this problem too, has it been fixed in the latest of updates? its a really annoying bug.

You must be doing something wrong. This issue "must" have been in all smartphone operating systems in the world, if what you are saying is the truth.
There's no way to drop the call, or press anything while you are calling someone. The proximity sensor doesn't allow turning on the screen when it's close to an object. The gyroscope also turns off the screen when you rotate the phone vertically during a call.
But all I can say is that it's not a bug, this is how is your phone knows when you are in a call, and you put your phone to your ear, or when you use your "speaker", and so the phone knows it's supposed to used it's speaker to transfer voice through the call.
Beside my poor English, try to move your phone a bit vertically before putting it close to your ear.

same problem here, also disabling ambient display... i also tested proximity sensor with some apps and it seems ok

I have that problem too from the beginning. None of the updates came up with a solution

Same here: I mute, turn on the flashlight or even open apps sometimes with my face. And thanks for the input @SmallTarzan but i know how to operate a smartphone and did not have any similar problems for the last five years. Apart from that annoying bug it's a great phone.

Wow, i dont know of this bug since i'm using custom rom from very beginning.
Try to make a call then use your hand to cover top part of the phone, screen doesn't lock??

I am having this issue too and it is really annoying

And still nobody came up with a solution???
It's easy to understand why it happens.
Proximity activates while you're in a call, but apparently the touchscreen digitizer remains working (even though the screen is off). Touching the digitizer with your ears or cheeks activates different actions while you think your screen is locked.
I can't believe how this issue is not fixed yet! That's a shame!
Same applies for the network fluctuation issues. You need to either choose 3G or 4G to avoid loosing your data connection.
Xiaomi that's more than LAME! You need to be ashamed of yourselves.

It happens to me quite often, although not always.
It's more frequent during long calls. If the call lasts for less than a minute or so, it doesn't happen.
Proximity sensor works, and screen turns off as soon as I put it at my ear.
Keyboard is off and not responding for a while. Then, all of a sudden the phone comes alive.
In my case it's not the torch. What I activate unknowingly is the handsfree loudspeaker, which can be even more embarrassing, sometimes.
Maybe it's because I am left-handed.
In an attempt to have the proximity sensor fully covered by my face, I tried to make calls by holding the phone with my right hand, but to no avail, after some time the screen wakes up regardless of everything.

Happens to me too. Although I did notice some differences regarding the position of the phone on my ear or which side of my head I put the phone on, I started pressing the power button long ago to turn the screen off. It may not be ideal, but it takes care of it.
