no problems here im just perplexed at the moment
okay this is insane how the heck does my phone know to turn of the screen when im in a call, ONLY when my head is close to it, i held the phone completely still and when i put my head close to it the screen turned off but when i moved away the screen turned on, though it was the accelerometer at first but now i dont know!
It's called a proximity sensor.
HTC and others have put this in many phones to turn the screen off when placed near your head, so you dont press buttons with your ears.
These things will probably do everything for you 5 years from now.
Just place your finger over the top of the phone screen and do it yourself. lol
The proximity sensor is located under the glass in the upper right corner of the phone, above the screen. There's also a light sensor. You can see them if you shine a bright light.

So does anyone know where exactly is the proximity sensor is on the TMOBILE TOUCH PRO 2. theres a website with some cool skins for the Tmobile version of the TOUCH Pro 2 and they have a cutout for it on the top right corner of the earpiece and i was telling them its not there and that its on the left side of the earpiece but i want to know where exactly is it at.
Its on the left side of the ear piece. You can test it by making a call, then put your finger near the left side, above the screen...the screen will shut off.
thanks man i was trying to tell the people at the site that its on the left side of the earpiece and they said their research and development team said its in the top right corner...
i went online and someone mentioned that the exact spot of it is just to the right of the "C" of the htc logo near the top of the phone.
Yep, right behind the HTC logo on the top left of the face of the phone. The sensor on the far left of the earpiece is the ambient light sensor.
So I have a PhantomSkinz screen protector installed, and I've noticed that now when I use the phone in a dimly lit room and make a call, if I pull the phone away from my face, it stays blacked out. I have to turn the light on for it to wake back up.
I'm trying to figure out if this is because of the skin or if my proximity sensor is f-d up. Anyone else experience anything like this, with or without the screen protector?
Haven't tried peeling the protector off yet, but I probably will. I already did a hard reset, thinking that might solve it...
Edit: I pulled off the screen protector, and what do you know! It works perfectly again! Is this just my phone or is anyone else's doing this? If others are having this problem, I'll call PhantomSkinz and suggest that they make a cutout for where the proximity sensor is.
It may quite possibly be the screen protector, I've noticed a small cutout in the top right of screen protectors that are designed for the n1. Correct me if I'm wrong but I believe that is exactly where the proximity sensor is located.
The proximity and light sensors are under the upper-(Edit: left) corner of the glass, above the screen. Most protectors don't seem to take this into account, and cover both.
Negative... the proximity and light sensors are at the top LEFT of the screen. Long story short, I carefully removed the skin, trimmed off the left corner (a bit too much), and reinstalled it. (yes, this can be done even days later if you know what you're doing. )
Anyway, the proximity sensor works fine now. Just wondering if others are having this issue or is my phone wonky?
so (my dense brain is clear) the prox-sensor is on the "top left" of screen (and opposite side of the led) as i look at the screen. . thanks!
you can easily see the 2 holes for the light and proximity sensors in the top left corner if you shine a flashlight at it.

both sensors are on the top left of the screen. the only thing in the top right is the charge LED indicator.
Can someone take a pic of exactly where the sensors are and possibly how they have "edited" their screen protector so it works better?
thanks

appreciate both of your clarifying responses. (now if i can only be convinced that nothing will happen to my phone if i root it! currently tapping the heels of my feet and repeating rooting your phone will not result in defect karma)!

I don't have a camera (except the one on the phone)... but shine a flashlight at the screen's top left region. You'll see two round openings underneath where the sensors are located.
As for modifying a screen protector to work properly... well that requires cutting material off. Either trim off part of the corner, or if you're particularly handy with an exacto knife, try to figure out a way to only cut a couple of circles or a long oval that will leave the sensors exposed. I just hacked off a corner of my PhantomSkinz, to verify if this was the problem... I have a replacement on the way anyway since this one didn't install right.
If you really want to do it right, go with a Seidio, Martin Fields, or other similar clear screen protector, as they won't have this problem.

Just tested in a dimly lit room with the Martin Fields protector which covers the emitter and detector holes. Sensor works as it should.

Yeah, I'm not surprised. I think the Martin Fields and Seidio (and any other "clear" protectors) are the only ones that will work properly without modification.
Btw, would you mind taking some pictures of your screen with the MF protector? Specifically, I'm interested in how it fits. You can post it in the Martin Fields thread in the Accessories subforum.
with my zagg shield the prox works perfect.

Not that I don't believe you, but you tried it in a dimly lit room, right? With the PhantomSkinz, it worked fine when it was brightly lit, or outdoors... just not inside when I have the lights down.
yep just tried it.

Cool... thanks man. So far it's just the PhantomSkinz and Skinomi that has been confirmed throw off the proximity sensor.
I've got the Phantom Skinz screen protector and am noticing no problems with proximity on the Nexus One. I did set the skin to be flush with the bottom of the screen rather than the top (the skin does appear to be about 1.5mm short), could this be the reason I'm not experiencing the proximity issue, even in a low light room?

It definitely could be... I had mine flush with the top prior to removing it. Either way, I think these screen protectors should be cut to cover the entire screen. I messaged PhantomSkinz Guru to suggest that he/she inquire about fixing the size issue and maybe getting a small cutout to the proximity/ambient light sensor area. I imagine a nice elongated oval, like those on phones where the speaker is on the screen, would work well.
Is this with full body or just screen protector?
Just the screen protector on mine.
This might seem like a dumb question, and I just got my MTS 2 days ago, so I'm still learning about it, but at the top of the phone, where the LEDs are, what is the function of the opposite side of where you hear your calls? Is it there for looks or does it have LEDs in there also?
it is the proximity sensor... it is what "locks" the screen so you are not activating it with your cheek while on the phone... it also blacks out the screen when you are on the phone
I've always wondered what this was too... thanks for that information.
it also turns the button lights and keyboard lights on/off at certain light levels...that way when its bright it turns the lights off and when ur in the dark the lights come on...i love it!

that seems to be incorrect because i use the headset and if i lift the phone to a certain angle the phone screen turns off, but when i tilt it back down it turns on again. i will look into this more but from what i have seen it is just there to be a little more symmetrical(would you want a phone with asymmetrical looks to it)

no hes right it IS a proximity sensor...go where theres some light and open the keyboard and see if the keylights are on...if so, try to make it brighter...(shine a flashlight at it or something) and the lights will go off...then put your finger over the sensor and the lights will come on...it works, try it...definitely not just for decoration...what you are experiencing is a perfectly normal effect of the proximity sensor doing what it does...no reason to look into it...
or download "Sensor List" from the market and look, it lists the prox. sensor and its data...put your finger over it and watch the output jump...
or run adb logcat and put your finger over it and itll come up with a entry about the light value changing...

without the headset try calling your voice-mail in a lit room and hold the phone away from you and move it all around an at different angles, you will see it makes no changes but just by putting your thumb over that spot it kills the screen and as soon as you remove your thumb it comes back on... might want to actually do some reading or testing before saying someone is wrong. not only would a quick 5 second test show that it is the light/proximity sensor, or you could try a quick google search
You can also have the left light flash for missed messages.
i was doing some testing and i am retracting my statement, you were correct wulf and i am sorry that i doubted this.
hey it's kewl we all make mistakes
what feature is this? when i put the phone near my face the screen goes blank and when i move it away from my face the menu lights up, pretty cool. anyone know how it works?
Not sure of the technical aspects, but I've heard it has a sensor - much like a car has headlight sensor. When it gets dark, the headlights go on, when it's daylight, headlights shut off. Phone is the opposite, dark to your face - light off, pulled away from face, lights up. I agree, cool feature - helps to conserve battery a little bit too.
It's a proximity sensor. The screen turns off so that it doesn't accidently register the screen touching your face as a touch input (aka your face touches the 'end call' button while in the middle of talking).
Lol all phones have done this using a proximity sensor for about 4 years now;-). It's nice though! Otherwise your cheek would press all kinds of buttons during a phone call, likely the end button as one of them.
These have been around for about six years now on mobiles.
Yes, this is nothing new on phones. If you're interested, look very closely at the phone's front, to the left of the speaker as you look at it. Opposite side of the camera lens. You may have to tilt it a bit, and bright light will help. You'll see two very small transluscent spots. One is the light sensor, the other is the proximity sensor.
Anyone else having an issue with the screen remaining off during a phone call? Screen won't come on during the call, won't even come on from the power button being pressed... So I basically can't even hang up a call on my end without rebooting...
Let me guess: you have a screen protector on the phone that doesn't have the proximity sensor cutout (below the right side of the top speaker)

I'm also having the same problem. Yes I've applied screen guard. But it has nothing above the display. Proximity is very far from the screen guard layer.

I'm having the same problem. Mine did have a cut out but its in the wrong place. If you put a light onbylur screen when it's off you can see where you sensors are. For now I use power button ends call until my new screen protector comes with the right cut out! You do can turn that on it accessibly
