Am I right in saying that there are four IR sensors on this device? I thought I saw one in each corner but lately, whenever I wave my hand over the bottom half of the phone, the screen does not light up.
Yes, if you want to see if they're all working, video record it with another phone or camera, you should see the IR sensors shining.

I tried with an iPhone and nothing came up...
Where is the fourth? Mine only has 3. Bottom two corners and upper right. Mine also does not light up if I wave over the bottom, but I can see the sensors firing, they give off a bit of red light. It's pretty easy to see in the dark, even with a naked eye.
There is only 3 and they are visible with the naked eye. Top right, and bottom corners.

I seem to remember mine working when I passed over the bottom, but now it is not. I can also see them glow red, but they don't seem to work anymore. Did yours ever work?
They never go right. The actual light is invisible to our eyes. You see the red dots when you catch it in certain light. But that's the sensor itself not the light its producing
Yeah my bottoms aren't working either, also if u go into attentive display, it doesn't work for me, the picture never pops up. Anyone care to give it a try, I haven't took the update, didn't know if that was anything for it.

Yup. Maybe an update broke it? I know it worked when I first got the phone then I turned it off.
Edit: they do turn on when I approach the phone. So I know they work.
I hadn't took the update so that's weird, idk hopefully it will be figured out. I see the sensors light up so their working I just can't figure out what's going on, glad its just not my phone.

The red dots go on and off when you move across the bottom of the screen. It's definitely not the sensor itself, because if you hold it in the same angle, the light also goes off.
As far as the bottom of the screen, mine has never lit up my screen by reaching across the bottom. I think the bottom sensors work in conjunction with the gyro, so that when you pick it up it turns on, but the sensors themselves never turn on my phone. If I wave across the upper right one it will though. It's been this way on all 3 Turbos I've had.
The 4th is near the middle on top. You can see them in this video.

The bottom sensors only work in a dark room for me. When the turn on they go bright then dim, and then they will sense my hand. Try it.

I just got a tilt about a week ago and ive noticed that in the middle of the screen there seems to be a purple greenish tint when put against incandescent light. The size of said glint varies in size but i'm unable to see what changes the size. Not sure if its heat or pressure or something. The touch screen works perfectly its just really annoying to always see such an annoying glint.
An interesting discovery is that when i press all four corners of the screen it disappears and when i press in the middle of the little square it seems to spread out. I feel like theres some kind of material or something in the touch screen that is causing this due to pressure. I keep it in a hard case in my pocket so the screen isnt pressed on inadvertently.
I've searched the forum for any answers but i havent seen anything about it. Any response or help would be greatly appreciated. I'll try to get a picture of it up asap but i left my camera at a friends house and dont know when im getting it back...thanks in advanced
~sayazs
Do you see the same "annoying glint" under neon light (not day / sunlight)?
Lots of NOKIA and SONY ERICSSON phones for example get this screen recolorization under direct sunlight - this has nothing to do with the screen being defective but with the plastic above the screen which breaks the light and shows you this colored spots. If you can't see the same spot under direct neon light then this might be the cause.
It is normal that you get color changes while pressing the screen in. First of, you press / bent the protecting plastic and the liquid within the screen which causes the incoming light to break in a different angle, therefore the color changes. (BTW: you shouldn't do that too often, it can cause permanent stains on your screen!).
There sure is the possibility that your screen gets pressure from underneath due bad assembling! If you're still under warranty, try to get a replacement.
yeah you cant see it in day light. but i feel as though there is constant pressure on the screen between the plastic and liquid since the spot is always there and doesnt really go away (unless of course in daylight).
well im thinking im going to go back for a replacement. thanks for the quick answer!
the iphone switches the screen off when it goes to your head then turns back on when u take it away. is there a simple app for this??
Phone lacks the proximity sensor the iPhone has. Fortunately, it has a plethora of other useful features (a keyboard, picture messages, etc.)

To add on to that the phone also goes to sleep when the call is connected and its just a matter of pressing the power button to get it to wake up again.
mine doesnt
Well mine has always went black when it goes up to my ear, but it would be nice if it came back on when removed from my ear.. although we dont have a proximity sensor, i dont see why it coulnt work with the gsensor/accelerometer. all it would have to do is go on when the phone is put back in the upright position

is it possible to in fact use the light sensor? it obviously recognizes something when it turns off, maybe write up something saying "when dark below 'x' threshold, turn off screen. when bright above threshold, screen on. you would have to press the screen somewhat snugly to your face, but it sure beats nothing.

It should be possible, but no one has done anything with the light sensor of turning it back on. I'm thinking that the polling of the light sensor turns off when the screen is in standby. If we can somehow get that to work in only incall (so it doesn't have battery issues), then it should work, when it goes from little light to more light, it should act as close to phone to far away from phone.
One could even use 2 sensors for it? Maybe the Light-Sensor and the G-Sensor. So when u bring the phone to your ear the light gets dark an the position upright. (the phone turns the screen off) And as soon as it get brighter and the position is change to normal (whatever that is ) it turns back on.
I reall would love to write something like that. But so far i have no clue of writing anything for that phone. Does anyone know a tutorial for writing software for a pda?
Thx
Come on guys this would be soooo great

It doesn't actually do that when you put it up to your ear. It's a WinMo setting to put the phone in standby after a call is launched or received. What you preceive as behavior is actually a timing thing.
The guy from pocket shield managed to combine these two sensors, g-sensor and light sensor, to work together as locking/unlocking behavior.
maybe some g-sensor and lumos code can handle this thing... and create one cab solution here...
if some one could write this code it would be an AWESOME addition to the Phone. I would personaly love this as im sure many others would.
Thanks.

So the IR sensors on the phone, the ones that are on each corner of the phone and detect movement so that it lights up the active display. Has anyone noticed this? When i wave my hands over the bottom ones, the screen doesn't light up, but if i wave my hand over the top one, it does. Does this mean my bottom ones aren't working? It hasn't really been a real problem, and I'm exchanging my phone for a different color anyway, but wondering if other can recreate this or if it is actually an issue.
Should only take a quick wave of your hand over the bottom bezel of the phone to see if the display turns on. Someone please take a second to let me know.
You have to be a certain height above the lower sensors for it to activate. I have the same issue.
I also have to look at the screen just right to make the screen stay on. Many times it starts to dim while I am reading and I have to adjust the phone. I also have to wave fairly high up to turn it on.

I could be wrong but I believe you have to wave your hand completely over the display for it to function properly. So its not unintentionally turning on with every movement near it. The command is a hand wave over the display, not the bottom of the phone. So I believe its working as designed.

I can make it activate by waving over the bottom half, but only when I do it a few inches above the screen.

i can activate the sensors when approaching from the upper part of the screen.
But not from the lower half (sensors below the display).
when seen in very dark room i see all the sensors (upper two and lower two) light up red.
i know that when the upper part of the phone is covered ,the sensors don't work because if the proximity sensor senses dark then it means ur phone is in ur pocket.
should i get a replacement . (really worried)
i did reinstall the moto app, it didn't help.
My Moto X has the same issue.
Edit, covering the top sensor may make the phone think it is in a pocket. I can wave over the bottom of the phone with no response though.

There's nothing wrong with your phone- the "sensors" at the bottom are just flashers and the actual IR receiver is in the top of the phone, so if you wave your hand too close to the bottom the receiver won't be able to pick it up.
Only the top right one wakes the device on mine.
I really doubt it's the IR. I believe it's the camera waking the device.

Why would you doubt something that is explicitly stated by the manufacturer? The IR sensor's sole purpose is for gestures, one of which is to show the Active Display.
Only top right corner wakes my phone
I don't think you have a problem. Try this:
If u simply wave at the top sensors, from any direction, the screen turns on.
For the lower sensors, try a bunch of different movements and you'll realize that when you reach for your phone (that means, moving your hand down and approaching the phone from the bottom part) the bottom sensors work.
My theory: the top sensors detect any movements, specially wave (from side to side) movement. The bottom ones detct the "reaching for" movement... If i remember correctly, the little demo you get inside Moto app tells you you can view notification by waving right above the screen or right before you grab the smartphone... isn't it exactly that which we are discussing?
Taking a shot in the dark here, but try going to the "Moto" app, hit the little gear icon top right and select actions. Then select "Wave to silence".
Now test it out, try swiping just above the top sensor (leaving the bottom sensors unused). Now try vise-versa (swipe across the bottom sensors while leaving the top unused). Notice how the wave action DOESN'T work when you isolate the sensors in this way. Now try swiping just above both of them with either your hand or with two fingers, one swiping the bottom and one swiping the top at the same time, you'll notice that DOES work. I think the only time all the sensors are used is for the action of waving to silence calls and things of that nature. When it comes to Moto Display and showing notifications, I'm pretty sure it's programmed to only use the top right sensor, as it wouldn't need three sensors to detect movement. Though I'm not sure why all three sensors come on when the display is off.

Again, there is only one actual sensor, the rest are just flashers, like little LEDs. The flashers send out IR, and the sensor picks it up. What this means, is if the sensor doesn't see your hand (ie, when your hand is only near the bottom of your phone) it's not going to activate anything. The IR flashers essentially bathe your hand in IR light, and the sensor is the component that actually sees it. Make sense?

I've read the same statement in some technical review.
Can't really remember which ones.
Don't replace your moto X. He's fine.
I've noticed on mine, the bottom two are easily visible in the dark, whereas the top right is barely visible, and the top left isn't visible at all.
I'm not sure if this is affecting the performance or not.

i did. The top left one doesn't light up at all, unlike the bottom two. This leads me to believe it's non-functioning.
I never noticed it before, but two tiny red dots appeared on each of the bottom corners in the capacitative button area. It looked like some kind of led, but they were very dim. I tested it and it looks like they appear when the micro-usb is partially in. Has anyone else seem them or know what they are?
I noticed them too. I thought they were sensors for the active display so when you reach for the phone it senses your movement and lights up the display. Not sure though, just a guess.

Yeah, your guess is spot on.
I do believe they are infrared sensors (hence why you can slightly see them in the dark as red-colored dots), and they are pulsing constantly to detect any reflection that would indicate an approaching hand.
You are correct, there are actually 3 of them, two on the bottom and one on the upper right corner.

Not in each corner actually. The bottom two and upper right. The 4th one is next to the proximity sensor and FFC. I saw it in a video posted on here before. Regarding the sensors that is.
Interesting.
Did not realize that feature was driven by IR sensors.
How do they tell the difference between an approaching hand, and being pressed up against your leg in your pocket?
The software is able to detect whether or not it is in your pocket based off of either the light sensor, IR sensors or possibly a combination of the two.

Wouldn't the motion sensor come into play in determining if it's your pocket?
I believe "Pocket mode" is determined principally by the "proximity sensor" - the same sensor that determines when the phone is against your cheek during a phone call and turns the screen off. When pocket mode is enabled, the "active display" is disabled, so it doesn't display notifications when it is in your pocket. I believe the pocket mode also disables the ir sensors, so it isn't trying to determine if you are reaching for your phone.

Correct. Cover the proximity sensor and give it a try. Shake the phone and wave your other hand, it won't turn on.

I could've swore I seen info about the v40 having a notification led. Does it have one or no?
I'm asking because a recent video I saw, stated it didn't have one.
Hehh, it doesn't. And I just noticed this after having the phone for 2 weeks.
It does have edge lighting when its locked/off tho. And that is really neat.

True, but who now-a-days doesn't automatically check their phone when they pick it up. Light or no light? Its instinct - at least for me - to pick up the phone and hit the screen to open it and look at my notifications.

Ok bro whatever that works for you. Lg 40 is not for you. Good luck
I've got a 1 year old now, and try to keep my phone usage to a minimum with her around, not to mention protecting my new LG from her grip.
My phone sits on the counter, and unless I see the notification light, I keep it out of the way. I've missed tons of messages, some concerning time related issues, since I'm not one of those "pick up the phone every 3 seconds millennial" types.
I never thought they'd take the LED away, so I didn't even check before I bought it.
Too late for me.
From my understanding none of the v-series had led notification light.. My last lg phone with notification light was the lg g2
Except with apps like Light Flow, the light means very particular things. Certain contacts, certain apps, etc. can all be seen from across the room or in the dark, where the AoD requires focusing and being nearby.
