is this possible in WM phones, when you take the phone outa ur ear the screen lights comes on? just curious

I don't think there is a WM phone right now that has this ability, however most WM phone are set to turn off display automatically after few seconds when a call begins, and it turns on auto when you finish the call.
I just don't get the point of wasting the battery to power the IR sensor just to turn off the screen when its near your ear! when the OS can do that job in an easy way.
I'm not saying it's not cool thing to have , but it's not necessary.
cheers mate

Phones with light sensors can do this, such as the diamond.

Please ask your questions in the Q&A Section of the forums.
Touch HD/Blackstone has a proximity sensor, like the oh-so 'lovely' (ugh) iPhone.

Solving problems that don't exist, one stupid app at a time.

yes there are wm phones with proximity and light sensors such as the the diamond/light, touch pro or fuze/light, touch HD/I think prox. the lg invite has a proximity sensor, I think the omnia has a prox too.
I think the light sensor is more versatile because u can have your phone adjusts it's backlight according to the amount of light around it.

Well, I wouldn't exactly say that. It has happened to me a couple of times that I accidentally ended a call with my cheek or by shifting the phone from one hand to the other and accidentally touching the screen. I have a Blue Angel, which is not exactly a small piece of equipment so changing hands during a long call is kind of a must (if you don't have a BT headset that is)...
Not a bad concept, however, duke911 has a good point. You can do this by software without having to have the IR, which is a pretty good drain in the battery, on all the time. Maybe a small script to change the lead time between the time the phone call starts and the time it takes for the screen to turn off. I don't know jack about programming but it doesn't seem like a difficult task...

Please move this discussion to the Q&A section

small hole next to the camera - what is it?

Hi!
if anyone wondered what are that little hole marked on the photograph?
Found in all versions Defy / Defy +
and it is not a second microphone

i hadnt noticed it till you put up this topic! :S
does anyone know what that is? now even i'm curious!lol

now i am curious TOO....

I gees it's the 2nd microphone, which is used for noise canceling.

Don't know what it is but it's not the noise canceling mic. That is located under the screw on the top right (when looking at the back with the battery cover off), there is actually a hole in the battery cover for noise cancellation mic.

Well its right in the middle of the phone, maybe its used during manufacturing?

I always thought it was the motion sensor myself.

Hole for a HW reset ???
Hi all,
While using my new defy+ with a CM10 rom, it was seriously blocked, without any capability to recover it, no USB, no boot, nothing could wake it up again
I decided to disassemble it, and found out that behind this hole was a kind of button
Isn't it a HW reset button ?
this question because once reassembled, my Defy booted again, came up to life again
Any idea, confirmation about this ?
regards and thank's to all of your contributions

Well it might be 18months late but It looks like a tiny external antenna socket or test connection, presumably used for setup and testing by factory/repair depot, judging by this picture:

Its a microphone used to record sounds while taking videos.
Try tapping the hole when recording videos and tapping the hole at the bottom.of the phone and see when you hear the tappjng noise

Did you try tapping it though?
I did try tapping it and it isn't the microphone! with the back cover removed and in record video mode I tapped the middle hole and the hole to the right, clearly the mic is on the right hand side just under the screw (where the hole in the back cover is, oddly enough) It would make no sense to have a mic made of brass and with no hole in the back cover for it to receive sounds.
On the picture above you can even see the mic has a little orange rubber seal around it, it's the square rubber just below the round orange rubber screw hole.

Yes i did try tapping it. I did it long ago to see what it was

hi, this hole is for water detector.
The detector is only a small paper which change color in contact with water.

[SOLVED] Faulty proximity sensor - hardware fix

Caution: not-so-skilled people ask for help to more skilled friends !!!
How a proximity sensor works:
Basically there is a modulated infrared emitter and a correspondent IR receiver. When the modulated light is reaching the receiver, the sensor will become active.
In the mobile phones, the structure is built like in the below drawing. When an object is close enough, the reflected modulated light will be captured by the sensor and it will activate it.

The problem in some phones is that for various reasons the sensor is hyper-sensitive. This should be translated to sensor becoming active when an outside object is even fairly far from the glass surface. But the problem is exactly the glass surface. The sensor is so sensitive it will catch even the refracted light from the glass (remember optics studied in school ?). Some of the light emitted by the emitter will be refracted from the very glass body back to the receiver.
The temporary fix was to "rub" the sensor area while in a call and suddenly the sensor was acting normally. This was caused by the fact that all that reflected light (from the finger) was supersaturating the sensor so, when obstacle was removed, the sensor was no longer hyper-sensitive, at least until the next power-up (next call).
The solution I tested (and apparently it works) is to create some sort of a light attenuator to place in front of the proximity sensor, but under the glass. Well .. the idea came to me while fixing an old remote control .
I'll let the pictures below to speak (thousand words for each ... pretty long story ) ... click on thumbnails for full 1200x800 size.
In case you are applying the mod, please leave a word here, so me (and others) will know the outcome.
I had not even a proximity misfire since I implemented this (roughly 48 ours ago) .
The opened phone (you will fond on the web lots of HOW-TO's about dismantling the defy):
The front case and the board - parts of interest:
Close-up:
Filler material :
"Attenuator" mounted:
View with the phone assembled back:

This seems really promising, I'll give it a try when I can find a suitable translucent material and post the results.

Very cool!
The proximity sensor is actually a part of the motherboard, interesting.
So in my case that my proximity sensor is broken and my LED is permanently on, the only way to fix it would be getting a new motheborad, in another words a new phone. Right?

A surprising fix for Proximity sensor problems

Hi there,
Quickly after installing a new screen protector sheet on my Motorola Defy, I discovered that it is causing my proximity sensor to be next to useless.
By peeling off the screen protector off the proximity sensor I verified the source of the problem. (The sensor worked properly without the protector sheet on it.)
I used a black permanent marker to mark out the proximity sensor area, to cut out a little window through the protector sheet with a knife.
Drum roll please, we arrive to the part where Newton got an apple to his head and Archimedes ran naked out of his house yelling "Eureka!",
The black permanent marker fixed the problem. once I painted over the proximity sensor (On the screen protector sheet of course!!), It started working fine again. Yeah. Weird.
Yes, Yes, I know, this is life changing information for many of us who just couldn't hang up after dialing the wrong phone number because of sensor problems...

wow.. epic fail on the part of the screen protector maker. did you bring this to their attention? good thing it has an easy, albeit, chinsy fix!

Long ago, I discovered something similar on the myTouch 3G Slide. That phone has a small rubber box cover over the proximity sensor, with a small hole for the sensor to peek through. When I changed the flex ribbon cable, the sensor wasn't working anymore. I eventually realized that on the old cable, there was that small rubber box over the sensor, & the new cable didn't have that. I put the rubber box over the sensor, & now it worked again. It seems that if the sensor is left wide open, it won't work right. I notice that on newer phones, the sensor is usually encased in its own little box in the housing. I guess they need most light around it blocked off in order to work right.

-nah, just a cheapie on ebay

This is a well known fix for the proximity sensor issues with aftermarket replacement iPhone glass that doesn't have dark enough tint over the sensor.. (cheap import products not oem) good to know it works in this case too.

Proximity sensor...

Hello.
I would like to ask about the operation of the proximity sensor in S20 (Exynos).
It sometimes happens to me during a call that the display does not go out when I hold it to my ear.
It's really few times, but it will happen.
Does the proximity sensor work at 100% or is it a defect?

When you are at a call, you'll see the top part of the screen flickering next to the front camera.
Thats the proximity sensor. Put a finger there to see if the screen goes dark.
If it does its working fine.
If it doesn't it's defective.

When I move the phone, the sensor flashes, when I don't move the phone, it does not flash, but the display goes out, but sometimes it happens that it doesn't go out until the next movement.
When I select the code *#77692#, the sensor still flashes and works at 100%.
When making a phone call, the sensor flashes only in motion, the pixel does not flash at rest, a lot of people have written to me that they have it the same.

Try going to settings- advanced features- motions and features. Then disable the lift to wake phone. That might be causing the problem.
