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!!
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.
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.
Hi, question: i have a Note 10+ with all updates and updated via adb to Android 10 but my fingerprint scanner is still really awful. I have seen all yt video, seen all tuto on how to set the fingerprint but nothing!
Still awful, especially when finger is a bit wet. Is there a solution or is it better change the phone?
Maybe it is the way you registerd your fingerprints, my fingerprint sensor is accurate all the time
Are you using a screen protector? Mine sucks too. I have a glass one with the thin area in the glad over the sensor and I have used privacy film and it's ehh. It works perfect with nothing on it. Try turning the touch sensitivity up in settings and maybe re-register the print again.

(The touch sensibility have nothing to do with the fingerprint sensor though.)
Maybe they finger print again but dont press to hard
Upside down

You probably have, but try registering your fingers upside down and side ways.. and register loads of times with the same finger you mainly use, im sure you know all this though
It's awful, specially compared to the OnePlus6T

, no, it is not, mine as many others work just fine, the fingerprint sensor for whatever reason doesn't work the same for all, odd, but not a so uncommon issue, and this happens among all brands
I partially blame the size of the sensor as well as the way they guide users through the enrollment process. The standard android fingerprint enrollment process, as i've experienced on my HTC U11 and Razer Phone 2, prompts for more finger edge samples. I actually went through the process on the Note as the software prompts and had mixed results. I then just decided to hit the sensor randomly with some overlap to give it a better overall picture of my finger as opposed to a bunch of samples of the same spot and then a few variants.
If you shine a flashlight at the screen you'll see the sensor size. It is a short rectangle that doesn't seem to cover the area that the fingerprint icon covers. I have an amFilm whitestone-style screen protector and while there is a slight difference, the stock experience was also not that great. I would recommend you try to figure out how you ACTUALLY use the fingerprint unlock. I noticed that while i'm enrolling i'm focusing on pushing with my fingers dead-on, in practice i actually use just the upper right corner of my thumb (if you're looking at the fingernail top-down). When I realized that I trained it with that in mind and it did perform better.
There was mention of the ones in the One Plus devices, which are actually different in that they are optical. Because they light up and read optically they have a more controlled environment than what the ultrasonic sensor on the Samsung phones. I can see someone with a deeper fingerprint patten be able to get better results vs someone with a very faint fingerprint. On oneplus devices though it would just be a different picture, but i'm thinking on an ultrasonic sensor there might not be enough peak and valley information to pass the threshold. Maybe samsung can make the pattern require less data points to match to unlock, but that would also mean it is less secure.
Bottom line is that while the tech has the potential to be more secure than optical under glass, it still has a little ways to go but it is serviceable once you get to it. I don't have big hands so i have to hold the phone in a very specific way to get a good grip on it. Once i figured that out, training the sensor again did yield better results.
I have the same problem. In sorry you haven't received a resolution, especially from Samsung who manufactured the Galaxy Note 10 Plus. I'm believe they were aware that it did not work with many 3rd party cases with protected screen covers. No matter how you register with screen off or on, the reader is intermittent and doesn't work with the cover. I hope you get the resolution as it will solve my issue as well.
The fingerprint registration process seems very glitchy too but after having experienced an awful 40% success rate with waking the phone using my fingerprint I deleted all the stored prints and started again. The secret is in storing decent prints so keep doing this until the phone unlocks with a 90%+ success rate like mine does now.
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.
