Ultrasonic Sensor? - Moto Z2 Force Questions & Answers

Kind of a random question but does anyone know if the Moto Display runs off an ultrasonic sensor? Considering there’s only one true proximity sensor I can’t imagine that powers the Moto Display like other moto models. Also if I’m in a well lit room and have the phone set on a counter or something I can hear a pulsing noise from the speaker until something gets close, then it shuts off and Moto Display comes up? Surely nobody has noticed that but I just randomly discovered it and was curious, CPU-Z just says it has a moto glace sensor

red light when in a call (weird)

there is a weird (faint) red light when I'm in a call, anyone know what this is??
(when I take a picture of it using my sensation camera it looks very bright but in real life it is faint like you wouldnt notice it until you look closer)
its there whether screen is on or off, and and if i put my hand over it it just stays lit
is it infrared or something to detect when my ear is near the screen??
My understanding is that is the sensor that tell the phone if your head is next to it or not.
As above, its the proximity sensor for turning the screen off when your face is near the phone.
There are loads of threads on Crackberry about it as their sensor flashes quite noticeably.

Approach gesture

So on my normal Z play, the approach gesture works pretty terrible (I've owned 2 and they were about the same). I have to basically slap or shake it. This is because I believe it uses just the proximity instead of IR sensors.
My question is, does this gesture work good on the Z2 play? Does it have IR sensors like the Z/Z Force?
Thanks!
I don't know if it has IR sensors, but my complaint with the approach on this device is actually that it's TOO sensitive.
Even as I type this, it keeps lighting up like a Christmas tree. I had the moto Z and it was perfectly tuned sensitivity wise, but something is definitely different on the Z2P. Movements that would not cause the og Z to light up keep causing the Z2P to. Hopefully moto allows configuration of the sensitivity level.
@cantsingh In my case it is also very sensitive, and find the way moto display shows notifications pretty useless.
So I just turned off the moto display, and use these free and "open source" apps instead: WaveUp and Glimpse Notifications. With those two apps the screen turns on when notifications arrive and/or when I wave over the motion sensor. The screen turns also on when I take the phone out of the pocket. This works great for me.

How does this phone know it ??? (actually, Moto Display question)

Does anyone here know how does Z2 Play (and also maybe X4, because it's almost equally good at it) know that my hand is "somewhere close to it" so it lights up its display ?
Initially I thought it's only proximity sensor, but I can move my hand toward the phone even from its side, and it "senses" its presence even from a few centimeters to the left or right.
Then I thought it might be the display panel set to some insane sensitivity level, but I really don't know...
Maybe it senses change in the environment around antenna ?
I've seens something about some "ultrasonic sensor" but X4 does not have one (at least it does not say so in its description) but is it used for Moto's "sense" ?
Most Probably the sensor to sense the Hand wave/motion is right under the Fingerprint scanner, just try placing a finger in the air right above the scanner and see

Hello everybody!
I am a person who all the time is looking for how to be more efficient with the battery of your phone I really like to disable GPS and disable the most things you can do and I just bought this LG G7 ThinkYou and I just realize that there is a laser invisible light powered on all the time on your frontal glass of your LGg7 check the video please:
note: THIS LASER LIGHT IS ONLY NOTICIABLE WHEN YOU SEE IT THROUGHT A CAMERA
VIDEO (YOUTUBE): watch?v=HAWa7vrp0Bk
And as you know I am caring if would that consume my battery and how to disable it (1), would that damage my eye vision (2), maybe it will finish life time soon because its all time on (3), what is that used for (4) my others mobiles don't have that (Galaxy Nexus, Sony Z5).

That should be the proximity sensor that checks if the phone is in a pocket so I can't disable the screen off gestures.
Yes, it's a proximity sensor, and it's important against unwanted control and activation of the display during calls or if is in pocket. It's an IR LED that detect the distance to +-5cm. Battery consumption is basically zero. About 10mA thanks to IR. And lifetime is hundreds thousand hours.
On a similar principle works TV control remote (you can see light with camera too if you press button) so it's safe to live.

Oh, I see. When it is in my pocket it should keep unlocked right? Currently I did disable this resource and it keeps flashing for what kind of proximity reason?
Hey I think its about the frontal camera maybe?
Yeah it is similar to the remote control of my TV launching laser when I press a button.
I notice when the back camera is recording also there is a laser light on the back glass.
No, its should be locked. Simple test: cover sensor with finger and do knock knock wake up. Display must stay off.
Laser on Back side Is focus for camera.

Camera dual-led flash

Hi all. There are 2 LEDs, but when flashlight is on, only one (on the top) is active. I thought the second one can be activated when camera is used, but no, it does not help. Any ideas on how and when it should be active? Can someone check this on your device so that I can know whether it is a hardware issue with my phone? Thanks in advance!
It seems that's a kind of light sensor, or infrared led - because it even doesn't shine when I apply external 365nm UV light source.
It's the second light sensor which measures light coming from the back side of the phone. When you shine a strong light directly on this sensor, screen brightness bumps up after a while. It doesn't happen if you cover the sensor by finger. The purpose is to have screen readable when you're holding the phone against bright background (window, TV screen...) and in my experience it's quite a nice feature.
