Would be cool if we could make something like the wimax notifier from the evo 4g on the 3d using this.
Thank you for your sharing.
Dude that would be amazinggggg! I loved wimax notifier on my og evo
Since this is device specific and doable with software it is more appropriate in the E3D section.
Have you checked the init scripts to see if anything is mentioned in there about it?

its an infared led, unless you can change your dna and grow new eyes you wouldn't be able to see it

Then how did all of us see the glow? And infrared is a red and you can only see it in really dark conditions.
take ANY infrared remote control,turn on you camera and aim it at the camera and press a button.Ive been testing remotes like this for years.

Most of the color cameras I have seen show infrared as blue. Having said that though those cheap infrared leds aren't purely all in the non visible wavelength.
IMO it's pretty obviously the infrared LED used for the proximity sensor. Notice how it is NOT red in the picture taken with the camera - it's purple just like infrared shows up on camera.
The user could have certainly seen it glowing, it may be broken, defective or he has slightly more spectrum-sensitive eyes.
You can try this out if you want. Download Proximity Sensor Finder and it will activate the proximity sensor when you open the app. The light is visible in dark conditions. If you look at the light through the camera, it will be purple and much brighter.

You have to activate the proximity sensor first which can be done through this app: https://market.android.com/details?...xLDEsImNvbS50aWdlcm1vbnN0ZXIucHJveGZpbmRlciJd
or look up "Proximity Sensor Finder" in the android market.

You have to make a call and then you'll see it. When I tried it seemed like a strobe, it was not a steady light.
I would LOVE it if the 3D had a second LED like was found on the 4G. As it is I think the fact that you can't see a notification while charging is a huge oversight.

I have the Cnet mobile review app on my iPod and the third picture down it really looks like there is a notification led! Probaly just light effects when they took the pic but I just found I should share this.

Does it light up? The common confusion is the proximity sensor (or front facing camera) looks very much like a LED at the top except it doesn't give out light

Should qualify that with "visible light" since technically the proximity sensor does emit IR light. Of course, even then visible is more a technical term than a literal one since some people can see the IR light emitted, too.
It really looks like it's lit up.
There is no notification LED.

NoLED to the rescue!
Sadly, there is not LED. HOWEVER, there is a very need app in the store called NoLED. What it essentially does is display dots (or icons) on the screen. And since in our case the note has AMOLED displays it will not consume energy for the black background. I used this app on my SGS2 and loved it. It's a bit buggy at times though!!
hope this helps
Hello,it seems there is no Q&A forum for this device, so here is my doubt:
Although the tech manual for the xperia S from the sony website report a proximity sensor, I fail to find one on my phone.
There seems to be a black oval spot on the glass next to the light sensor as if some sort of sticker can be removed to install the sensor.
The light sensor seems to work, since I've seen the screen go darker and brighter, but when I'm in a call and put the phone in my ear the screen wont shut off like in my old SGS nor will it turn on when I move the phone away from my face.
are your phones like mine? or is mine a defective unit?
I guess ur device has something wrong with it.
By the way; did u place a screen protector?? Coz if u did that may be the problem!
I think the light and proximity sensor are the same.
There is something wrong with your phone,maybe you should try to flash a new firmware.

Hi,
Mine works fine...
Do this:
1>Go to dialpad and type *#*#7378423#*#* (*#*#SERVICE#*#*)
2>A menu pops up in that u will see service tests select that
3>Then scroll down and select Proximity Switch
4>Initially it will display as OFF. Now u place your finger or hand on the Proximity Sensor, then the value of Proximity Switch on the screen will change to ON.
If this is working then the sensor is just fine u need to update the firmware else u need to go and replace the piece IMO though.
Thank you all for the feedback.
I used the service menu to check the sensors ...
indeed the proximity sensor is always off, even when I put my finger on it, it seems someone forgot to remove the black paint from behind the glass, but I will update it anyway to make sure before returning it.

sensor is IR, so darkened window is normal for it. but if it have always closed windows - than its status must be always ON. so, most likely you have faulty sensor (or bug in firmware)

If it was covered by the glass/ cover it would show OFF because the glass doesn't radiate heat like your body does.

Proximity sensor on phones does not react to heat. It have simple IR transmitter, which emits a beam, and IR sensor, which react on reflected beam.

You are right, just tested it and it seems to be a reflective sensor.
thanks for the tips, it was indeed a faulty sensor and they gave me a new phone right away .
I hope I don't get any more problems like a yellow tint :X (knock on wood with fingers crossed)
That I am facing the issue of a blue dot appearing in both rear and front camera of POCO F1 when shooting against the light in low-light. For example shooting a bulb etc. It is pops up even in daylight when the photo is taken against sunlight, but in day it yellow. Is it a defect? Tell me at the earliest so that I raise a replacement request. Official statement would be much welcomed.

This is perfectly normal.
Most camera lenses when pointed at a light source cause a light orb or ghost flare. Here are some links that explain this.

Hey, have this phone from yesterday, europe dual sim version. How is for you the 3d face unlock?
I feel it's often inaccurate and in these cases it it does not unlock the phone.
Also, when i am in a dark room wit a good light behind me it's often inaccurate and, again, in these cases it it does not unlock the phone always.
In fact, if you try to register your face in this last condition you will see the face very very dark and this is a problem obviously for the face unlock.
I remember this last same "dark" problem also with the P20 Pro sensor.
What you think? Any solutions? Maybe in next updates?

just dont register your face in bad lighting conditions where it cannot be registered properly. I dont understand your problem tbh. Face unlock is a combination of the infrared thing and the camera.... if you use your phone while sitting in front of a bright light you cannot expect it to work. its like having wet or dirty fingers and comlpaining fingerprint isnt working.

With my iphone x in the SAME condition the face unlock works ALWAYS instantly, so i can see the difference.

Well if you register your face in good lighting and the unlock does not work in good lighting then there is probably something wrong. You should contact huawei about that.
If you are trying to create a bad lighting condition on purpose and then it doesnt work I am not sure why you do this. There is no point. If you are in everyday live, like in a bar or pub and the lighting is bad you have to expect that face unlock is not going to be the most reliable. Its that simple. Sitting at home and trying to push it to its limits does not benefit you at all.
It is not as secure nor the same technology as face ID so there is no point in comparing them. If FaceID is better you have to accept it. No update can change the hardware.... maybe it will be optimized but it is not going to improve by 100%.
Surely ambient light has nothing to do with the face unlock method used here, as the camera is searching for an IR dot pattern. If anything, I'd expect it to work better in the dark.

It works in good light but it's not accurate like FaceID or also other 2D unlock tried until now. It's not accurate, for example, when I'm sitting in an armchair often it wants certain angles to unlock, etc..
I can understand your point about create "bad light condition". Until few days ago i had a One Plus 6 with 2D face unlock, but not only it, and in the same Mate 20 conditions i had no one single problem with angles or light behind me! Maybe it's a bit hard to explain..

In fact it is the same thing that I thought! "Better in the dark", but in the evening when there is an artificial light behind me, sitting in an armchair, the unlock starts to have a bit of difficulty. And instead it should be the opposite, it should work better.
In this situation if i try to register my face in fact i see my face really dark cause the light behind me goes exactly on the sensor. Same thing with P20 Pro sensor. Only with Huawei i have seen this "problem". Nor with Samsung, nor with One Plus nor with Pocophone, etc..
It's really strange.
Check the software/EMUI problem thread, see if anyone else is reporting it. Otherwise, it's news to me.

for comparison. I just tested bad lighting with my mate 10 pro... worked just fine... immediate unlock
i am not sure about the IR thing. it should definately work with no light but i am not sure if it is able to "work against" light. if your light sends out inrared wavelengths it will definately interfere with the IR projector. I am pretty sure though it sends out infrared wavelengths since it gets hot.... heat=infrared light (that how heat cameras work).

Apple were the first to introduce dot-mapping (or whatever they call the technology) to scan all areas, from left to right, of the face. The android versions on phones is more watered down...but it seems Huawei are using their own software of facial mapping which I imagine is designed to work the same as Face ID on Apple...but as there's some bugs with the pre-releases, I'd potentially wait and update the phone in 3-4 weeks to see if it resolve the issue.

It was perfect in my "condition" with mate 10 pro with light behind me and against the cam. Because it used only the frontal cam! When i tried to register my face with Mate 10 in "my condition" my face was no dark and clearly visible!
This IS a big difference and here there is an "error" starting from P20 Pro to Mate 20 Pro.

Yes, completely agree with you.
But i have a little doubt, this last comes from P20 PRO, also this with light behind me and against the sensor shows me my face all "dark" and obviously no update "fixed" this. I remember with this phone in my situation was IMPOSSIBLE use the 2D face unlock.
Idk honestly if an update here can improve this kind of sensor. I hope!

Facial recognition evidently hates sunlight. If your face is side on to the sun it won't work, you have to either be in shadow or directly in the sun. The fingerprint scanner I'm also finding to be very hit and miss. I have just been out using it to take some photos, lost count of the number of times both methods of unlocking didn't work.

Edit...
It seems to me like a directional or sensor spread issue,
If i hold the phone level with my eyes and head straight (straight neck) it works perfectly, if i'm at my desk with it in my hand looking down at it then it doesn't. If i raise my head and phone vertical as its giving me the 'recognising face' message then it unlocks just as i hit vertical/straight neck.
Problem is i look a t**t raising my phone every time i want to unlock it (looks like i'm checking myself out in a vanity mirror!!)
Had the iPhone XS before this and it worked flawlessly head down or not.
Can someone else who is having issues test this theory?
Edit......
