Hi Guys,
Just wondering what your thoughts and experiences are on this:
If I use the Quick Glance Motion mode in the N2... I believe constantly keeps the proximity sensor fired up.
Can this continuous and prolonged use damage the Proximity sensor? I bought my phone outright from CL... so I am not quite covered for replacement with Sprint if that happens, so I wanna be safe than sorry... thanks!
Well, I've not heard of this happening, however there are two parts to the sensor.
There is an IR emitter which is a simple IR LED like you'd find in the front of a remote control. You can verify this is working by looking at the face of your Note 2 with another CMOS based camera such as those on another cell phone. The 1st hole to the right of the speaker at the top of the phone is the IR emitter. You may be able to see a faint red glow from it as well when it's active.
The other sensor isn't as easy to test, the IR receiver which is the 2nd hole to the right of the speaker. One option is to use the built in test mode by going to your dialpad and entering *#7353#
After that its option 11 I believe for the prox sensor test. It's fairly simple to use.
In the end, proximity is a very simple IR light and receiver. nothing fancy to it. It's not out of the realm of possibility, but out of the things that could break on the phone those would be my last guesses.
Good luck!

Thank you aramova, for walking me through this stuff. I have to admit, I have never hear of this sensor going bad due to continuous and prolonged use, but something about the sensor staying red/orange in color, all the time made me think... something could go bad here... guess not, since no one reported this ever...
If anyone else has something different to report here, please share guys... Thank you!

Easy FIX!!!!!
I took a can of compressed air and blew it through the top earpiece grill a few times and Voila, it works great now!!
I actually used a Old perfume can which perfume was over and it was only pressing Gas OFF!!

Is everyone 100% sure that the TMO TP2 doesn't secretly have a front-facing camera? (just like how the HD2 secretly had extra RAM)
I can see the hole, exactly where it is supposed to be in the international version. I'm wondering if there is a camera behind it.. or just a hole...
I just realized that the hole was there after looking very very closely. Its to the right of the speaker that you hold your ear up to.
Just some food for thought
EDIT:
-Oh and its not the proximity sensor, that's on the left side of the front speaker
-And I put my phone on auto-adjust backlight and when I put my finger over it, the backlight doesn't change so I doubt that it is the light-sensor either
i know what ur ralking about i thought that it was for more sound, like a bass or something

Make a phone call and then cover that hole with your finger and see if the screen turns off. My guess is it's the proximity sensor.

the proximity sensor on the tilt 2 and similar touch pro 2's is above the c in htc. if you tilt the light just right you can see it. the european touch pro 2 has the camera where my carrier logo is. im not sure what that is on the tmobile version but i dont think its the camera. or even the proximity sensor.
The front-facing camera on my UK TP2 is a lot further away from the centre of the phone than that.
That is not a camera. That's the light sensor used to auto-adjust the screen brightness.

When I adjust the lighting for only the spot where I think the camera is, my phone does not adjust its backlight...
So you could still be right, but right now I doubt its the light-sensor

Actually it does...try this: hold your thumb over that spot for about 5 seconds, then pull it away...within 2 seconds the screen will probably dim. I just did this test at my desk, under normal flourescent office lights, and that's what happened. I repeated it 3 times with the same results.

no thats not the light sensor. the light sensor is the speaker grill on the right. it looks like a notification led that never lights up. still not sure what that circle is but i have a feeling its nothing.
I was applying my tempered glass screen protector and after everything was done, I did a thorough check to realize that my laser sensor has hairline scratches. Will it affect the focus or performance? It's my first LG phone..
Thank you in advance!
My laser appears to have a few tiny scratches as well.
Highly doubt it will hurt anything. My g3 laser was scratched up and it seemed fine.
I was thinking of polishing the plastic and applying a film protector to get it protected. Any idea if a film would affect the focus? Thank you for the reply.

Anyone got preventive measures to prevent laser focus plastic cover from getting scratches further? Mine is quite scratched up and I'm pretty annoyed by it. I believe it won't affect the focusing speed but it's a flagship phone from LG and yet such thing happens..

The laser cover is soft, cheap plastic. Nothing you can do about it. No, it won't affect the focusing unless you put a giant gash in it that will deflect the beam. Same thing was happening on the G3. Just be careful about it.

Polish it with ABS polishing compound, then put a drop of optical hard lacuqer on it. More trouble than it's worth, IMHO.
Although LG brands it as "laser" it's nothing more than a ray of infrared shot and measured after it bounces off obstacles. So unless the emitter/receptor is REALLY weak, there will be likely no effect on the focus.
Double that with the fact that the camera uses both the "laser" and phase detection to focus, if the "laser" fails to provide focus information the phase detection will do (slower).
Think of it that way: Do you care that much about the scratches on your TV's remote infrared emitter?
Don't worry, your "laser" is fine

I don't think you really know what a laser actually is.
The whole point of the laser-assisted autofocus is to project a tightly focused, coherent beam of light shining in a single direction so that it reflects off the photo subject and nothing else. A non-laser IR diode projects light in a "cone" in all directions, which is useless for focusing the camera. It is a laser by all means, otherwise it would not work at all.
Scratching the cover might diffuse the beam slightly but only a major gash will actually impair it to the point of uselessness (since it will scatter the light in many directions).

I know very well what a laser is, thank you very much
http://www.anandtech.com/show/8062/a-closer-look-at-the-g3s-ir-laser-auto-focus-system
A "perfect" laser would be actually counter-productive, for unless you have a sort of "crosshair" on your viewfinder to mark the focusing point, you may very well have your phone focus on the tree behind your beautiful significant other, just because your subject is not in the laser's line of sight.
It is actually necessary for this concept to work that the beam is conic. Here, see this image from LG's own keynote: http://androidspin.com/wp-content/uploads/2014/05/LG-G3-Laser-Autofocus.png
If it was a super-focus laser, would they represent it as a conic, albeit very narrow, beam?
They don't need a "perfect" laser emitter to work out their concept. Granted, they need a narrow beam to avoid interference and allow an accurate measure of the scene being captured but a perfect laser beam (perfectly coherent, single direction light) would just do more harm than good. This is not used for sniper rifle or whatever, it's used for focusing on a scene.
Scratches will maybe deviate a portion of the beam a little but the majority of it, unless the window is completely buffed, will still serve its purpose. I'm strongly guessing that the way it works is: Send a burst, receive reflectionS (plural because there will be more than one) and apply some algorithm that'll define the most appropriate distance to focus on, based on the collection of durations from the receiver.
So I have a question on this topic. Since its supposed to be infrared, on a remote, you cant see anything being emitted unless you look at the emitters through a camera or something. When I have my camera on my G4 on, I can see a tiny red red light shining. Can anyone else actually see the red light being emitted? Just making sure mine's not defective.

I can see it too. Very much like you can see the IR emitter of your TV remote, except it's more focused here so even more noticable. Your device's fine
More on why we can "see" infrared in certain conditions even though it's out of the visible spectrum: http://phys.org/news/2014-12-human-eye-invisible-infrared.html
You'll notice that the "laser" is pulsing rapidly, which is the required condition to trick the eye into "seeing" the beam.
Guys I noticed a couple weeks ago, if I tap on the back of the phone, right behind the top speaker, it makes a noise. Sounds like something loose in there. Anybody else hear this, or is it unique to mine? (maybe warranty issue)
having the same noise

Maybe hardware related then, thanks damn66
Same noise here. Glad it's not just mine.
a small consensus seems to attribute this to the camera auto-focus mechanism. it should 'clear up' when the camera is in use.
also noted that the same thing happens with a 6P (from nextbit forums)... sounds like a reasonable explanation.
Bringing this thread back from the dead because I have a similar noise. I found it's the lense covering the flashlight. The lense moves a little when I tap it with my fingernail and/or if I shake the top of the phone. Anyone else having this issue? When I turn on the flashlight, only the top LED lights up. I just got my Nextbit Robin. Thanks.

The bottom LED lights only light up when using the flash on the camera app and taking a photo. The lens for the dual tone flash shouldn't move though.
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.
First time with an in screen finger print scanner. It seems the Pixel 6 turns on at maximum brightness (regardless of the screens brightness) a circle under your finger as you unlock. This is very bright in a dark or dim room, causing my finger to glow bright red, sure I can see bone!
As I understand it the finger print scanner is just a capacitive scanner under the screen, so not something that "sees" justifying the bright light, so why is this happening? Is it just something Google thinks looks cool without giving much thought to it, or does it have a purpose?
I'd really like to get it toned down so it's not so jarring in a dark room when using at night, but see no settings to allow this, is there a way to change it?
Struggling to see how this is any better than a rear fingerprint scanner.
It's not capacitive, lel. How would that work? It's hidden under the display.
It's an optical fingerprint scanner. And optics means it requires light to function.
There are three main systems in smartphones: Capacitative, optical and ultrasonic. Google opted for an optical sensor on the Pixel 6 (pro).
Without light, the system can't work. It requires a combination of light and dark.
A capacitative fingerprint scanner uses an array of tiny capacitor circuits to cllect data. How would you exchange/store electrical charge, if a glass panel is between the scanner and your finger? It's just not possible, from a simple physical conditions standpoint.
It's working as intended.
Besides, it's simply NOT better than a rear fingerprint scanner. The old Pixel rear scanner was beatiful and just worked. In a dream world, the Pixel 6 would have faceunlock AND a rear fingerprint scanner, so we can enjoy unlocking with ease at home and use the fingerprint scanner whenever we wear a mask in public.
But, we are not in an optimal world.

Many thanks, I did Google it after posting and found it was a CCD device so optical, should have done that first! I thought it just worked the same as the rear ones but just placed under the glass. Everyday is a school day, guess I will just have to use a pincode when its dark.
Must say I find the rear scanners much easier and natural to use, I don't see these personally as any improvement.

You're welcome. I agree with you here, I liked the Pixel 2 and 3 scanner at the back, with a case on you just had this "easy" resting and finding place with your finger. It just "moved" naturally into the hole and unlocking was never a problem.
Sadly, Google decided to opt for another solution.
I edited my previous post btw with some more info about scanners, maybe you will find it useful.
I think it's a shame that Google doesn't use the latest technology for its fingerprint sensor. Google developed the Tensor chipset in collaboration with Samsung. Why didn't you just adopt the ultrasound technology for the fingerprint sensor from Samsung? In my opinion, this technology would be a perfect fit for the Pixel 6. Has it probably got too expensive for Google or Samsung doesn't want to share the technology (yet) with others? In any case, it's a shame.

Maybe it had something to do with the supply situation, many parts are only hard to come by.
Pixel 7 next year got to have a reason to upgrade. I can see the return of a rear or ultrasonic in display + face unlock as a feature heavily marketed lol
Google is trying to stay up to date with the cool kids. That optical sensor is a gimmick nobody asked for. It's not nearly as fast or precise as the rear one. But hey, at least it's "cool".

I believe what's supposed to be potentially better about them is that they don't take up as much space in the phone, making more room for other things (like the huge batttery). I could be wrong about that.

It is my theory that they have an agreement with Samsung to not make their phones "too good" (gimp them), in exchange (and money) Samsung provides them some parts. For that matter, Samsung could've just refused to license certain technology to Google. I'm glad at least the storage is UFS 3.1, from Samsung.
I suspected it was more for looks. Trying to make themselves look more mainstream.
