Red Light near Proximity sensor Always On - Sony Xperia XZ Questions & Answers

First of all I am not talking about Notification light.
A Red light in proximity sensor next to sony logo is always on when device is connected to wifi, or when connected to mobile data only whrn the arrow indicators appears.
This red light is on even if i disable adaptive brightness.
I am shocked why no one raised this quesrion.
Hence here I am.
I hope this is not intentional by Sony.
Coz ffs i cant get one thing to my mind that how it is helpful. It is rather annoying.
Anyone with a clue pls share.

It's on on my phone as well. It was also like that on my Xperia X

I call it the "I'm watching you." light. I think its the proximity sensor's lazer. I dont think it should be on 24/7, but then there is this "Led light's lifetime depends on how many times they are turned on/off" thing. May be it is some kind of an optimisation?

It definitely has to do with data recieving signals.
But whatever it is for I am concerned about battery life
It is just plain stupid of sony to not recognize this.
Coming from z5 I thought speakers were average on z5, but I doubt XZ even have any speakers at all.
Sound is that bad on XZ. I can barely listen to ringtone and I was sitting right next to the phone. What if we are in the other room or @ some distance? We' ll definitely miss the call.

Disable adaptive brightness and the flickery red dot will go off. I can only see it in a darkened room so it doesn't bother me. I'm looking at the screen lol!

so u say that red light turns on only on lock screen...what happens when u unlock the phone is it still on (red light)? becouse mine is always on except when screen is locked and turned off course and then it turns on again when i turn the screen on...this is how sensor should work... If urs doesnt work that way then go send the phone to waranty... I wouldnt investigate anyomre just go to Sony.

Until yesterday it used to be always on, but now only on the lockscreen. It stays off when I unlock the device.
Why can't we seen to find the real use of that light?
Is it even a feature?

looks like this proximty sensor works that way by having red light turned on...so does ur adaptive brightnes still work after it turns off when u unlock the screen?i feel its faulty sensor!i can share u my experience with Z5...i had white spots on screen so i send it to repair and they replaced the screen but also they managed to break proxity sensor aswell... i actualy laughed out loud how can they be so careless ahhh nwm hope u fix it soon.

Well now I get it, atleast I think so.
Red light stays on if we turn on adaptive brightness.
It also turns on when data packets are being sent to our device (via wifi or mobile data)
But why? That is the main question here.
Previous devices never had this feature, and what diff does this make?
Looks like my adaptive brightness works fine.

Do you mean the light in the attachment?
It should be the infra-red light used by the proximity sensor anmd it is not meant to be seen by human. I can only take this from the camera of another device but I cannot actually see it.
Trust me, if you tries to use the camera of another device to view it, you will see it blinks a lot when the screen is on.

That is exactly what I am talkin about.
It is not supposed to be visible for naked eye until you use a camera.
This one just stays on. Doesn't blink.

OK so looks like im having a camera in my eyes LOL cuz i can see that red dot light constantly turned on...ill see what Sony will say about that.im gonna call waranty just for curiosity.maybe they know something

There may be some variation of the wavelength produced by that LED from device to device, while I cannot see it in my XZ, I can saw it in my last LG device. It won't cause any battery draining problem because either you see it or not, it is still blinking.

My God
This is not a problem
By using this proximity sensor our phone controls the automatic brightness setting.
which is called Adaptive Brightness

hey buddy we all know that but we just want to clarify why some ppl can see the light and some not.... read next time

Xperia X and XZs does this and its annoying, Sony obviously did a bad job in defining what's visible to humans.

Light Sensor not functioning well

Hi, the light sensor on my TP is not as sensitive as it was before, i used the sensor test utility and it reads dark in fair light, and it barely changes values when moving from outdoor to indoor..... my screen protector is partially covering the sensor, i removed it completely but same result, is there a utility to adjust the sensor......... please help
Also having this problem, the light sensor doesn't seem to function at all..
Same here, my sensor doesn't seem to work from what I can tell (is it next to the speaker at top?).

Is there any information about an upcomming firmware update by HTC? i'm having troubles with loads of bugs atm..
the only time i noticed this problem was after installing PocketShield http://forum.xda-developers.com/showthread.php?t=430541 .... but im sure i did not have this issue before.
I have had 3 touch pro phone's now becuase i had some issues with the screen, but all of the phone's that i had had the same problem with the light sensor, it just doesnt word properly.
We need a rom update!
Try one of the bubble level programs from over on the Diamond apps forum. Sorry I don't know which one and i don't have time to try right now, but it has a light level meter that show how many ansi lumens the sensor is registering.
Just put your finger over the sensor and see if the display dims, then remove your finger and see if it brightens again.
This test works fine on my TP.
not that much result here..

used to work, but not anymore.... i can only notice the screen change when moving from indoor to direct sun light
Go to battery options and turn the light sensor off. You'll see immediately that screen will light up. Turn the light sensor on again and the screen will darken

Clockwork 3.0.2.5 Bug?

Did anyone else notice that their LED will faintly flash red after flashing 3.0.2.5? It has to be real dark, but I can see it flickering. Anyone else?
Not happening with mine in a pitch black room. Might wanna make sure you removed the previous version completely. It's in the options somewhere.

Do you mean the light shows in general?... or only when you are in CWM?
If the former, I am still on 3.0.2.4 and have seen this faint red light myself when on a phone call on occasion. So it would not be a new bug with 3.0.2.5
This is the first time I have noticed it. I tried re-flashing CWR and there is still a faint red light.
Not positive, but I think that's the proximity sensor's light you are seeing. Try to watch it through another phone's camera if you have one handy, the sensor should detect the infra-red (near infra-red?) and it should look brighter.
Just tried it myself and it is indeed the infrared from the proximity sensor that you are seeing. As to why CWR would be using the proximity sensor, that is a whole other issue =)
I also noticed this on my phone then walked over and grabbed my wifes bolt that is stock and not rooted and hers does the same thing. Very faint red flashing light. Hers is stock so it must just be the phone
The infrared sensor will pulse intermittently to see if the phone is near an object or not. To tell if the phone is by your face, upside down, in your pocket, etc.. Don't worry pulses of this sensor don't take much juice at all. I'm just surprised you saw the light at all lol most people wouldn't be able to.
Maybe it's my new glasses
I'm glad it's just not me and/or my rooted phone.
I only get that light to show up when I got Skype running in the background.
faint led flicker in earpiece
mine is doing this too, but I don't have "clockwork"-i don't think. I've noticed that it's not the "main" led, but it is right beside it!
anyone have any ideas about what this could be!?
it is, indeed, skype, and i believe it IS the proximity sensor. why?... i have NO idea, but i feel better now that i know the correlation and that I'm not alone!
I found out the proximity sensor AND Skype was the cause of my battery issues.
Obviously nothing to do with CWM.

Notification LED?

Is there not a notification LED for the Charge? You know, when you get a message or something? My Droid X had an LED indicator light that would flash until the phone was checked. For the life of me I can't seem to find where to enable/disable this? Please help.
It does not have a notification LED, quite disappointing for such a high priced phone. Just like the galaxy S2, even with its insane specs and high praises they still couldn't manage to put a notification LED, I'd rather have that then a front facing camera
You can use the free app NoLED if you would like a way to simulate having a notification LED
The led not being there has been a big con for me but if that's the worst I guess I can live with it. I would not reccomend using led "simulated" apps as your battery life is killed by them because of the screen being in the on state

Ya that is true, I'm also pretty sure it keeps your phone from sleeping since the screen is on which of course means even more battery drain. Just recommending a way to simulate the LED though I'm hoping someone makes an app to just have your back LED(for your camera) do a small flash every 15ish seconds, sure most people set their phones face down but still!
Missed Message Flasher works for me with few complaints.
NOLED I didn't care for.
What are the small circles up at the top of the phone on the right for? Photo sensors of some kind?

I'm thinking they are sensors to detect light and adjust your screen brightness and I know one of them detects when your face is in front of the phone while on a call to prevent the screen from staying on..

[Q]Two LEDs on the front of phone?

There are two leds on the front of my inspire i obviously know what the one that is under the speaker mesh is for (lights up during notifications) But what is the one to the right for? Iv never seen it light up and i searched and couldnt find any thing about it.
Im basically just wondering, Thanks for any help in advance.
It is a proximitiy sensor, turns the screen off while your in a call. So while its up against your ear, you dont press buttons with your face.
Not 100% on this but Im guessing its used for the automatic screen brightness.
Oh ok, I honestly didnt even think of that lol. It just looks so much like an LED to me atleast lol.
Thanks for the quick answer.

Verizon LG V50 Proximity sensor problem... maybe

Greetings.
I just picked up the Verizon variant of the V50 and have a question, hopefully someone with a V50 can help me out. My proximity sensor, which is supposed to only be active during phone calls to shut off the screen, seems to be responding to darkness. If I'm in a lit room and the screen is locked, the phone shows the "Always on Display" like normal. However, if I turn off the lights, the screen goes black, the fingerprint sensor does not respond to touch and I have to press the power button multiple times to get the screen to activate. If I turn the light back on in the room, the AOD comes back on and the fingerprint sensor responds to touch.
I took a trip to my local vzw store hoping they would have a V50 on display to test this since I don't know if this is a phone feature or a defect. I'd hate to go through the hassle of swapping phones only to have the new one do it too.
I do have a screen protector on the phone but it is not covering the proximity sensor.
Can anyone with a V50 test theirs to see what happens and let me know? I'd appreciate it.
I just tested this on a Verizon LG V50. Almost pitch black while on a call:
- Screen blanks when I put it up to my ear
- Screen lights up when I pull it away.

Mine works fine when I'm on a call, it's when I'm not on a call. What if you have it just sitting on a table and you turn off lights and make it completely dark in the room? Does the aod turn off or stay on?

Or try this. Have it sitting face up on a table with the AOD on and put your finger over the earpiece/proximity sensor area. Does the display turn off? Mine does and I don't think it should. My V30 didn't.

Sorry, it was late when I responded and I neglected to mention that.
When not on a call, in pitch black, covering the screen doe not blank it out. Only when on a call does it blank when you cover the proximity sensor.

I appreciate your help. What about in regularly lit room? With phone showing the always on display, if you cover earpiece area, does display turn off or stay on? On mine, just sitting on a table in a lit room, and it's showing the clock on the aod, if I cover the earpiece display turns off. Sounds like I might have a defective device.

OK....Let me apologize once more. I missed the AOD part.
AOD turns off when covered regardless of light or dark environment. You want this to happen. The regular home screen does not blank except during a phone call.
You want the AOD to blank such as putting it in your pocket. This is an OLED and they burn. I have a Galaxy S8 where you can see that I used Waze a LOT. I would say that this behavior is normal.
Sorry about the confusion and missing where you asked for AOD.

No problem, thanks for your help. Can I ask one more thing? With the AOD on, with phone sitting face up with no obstructions anywhere and you make it pitch black in the room WITHOUT covering or touching the sensor. Does the AOD stay lit up or turn off?
In that scenario the AOD stays on.
Went in to a room with AOD on. Turned lights off....AOD stays on.
Turned the lights back on and then off to test. It stayed on.
As soon as I cover the proximity sensor with my hand, it turns off.

I have the same problem. And I have already discovered that it is clearly a failure of the proximity sensor since with a sensor testing application it tells me that I have an obstacle 0cm from the screen. Have you managed to fix it?

Try this. Ensure there is no screen protector over the selfie camera. Either cut a relief or use a pre cut protector for v50s/g8x. It worked for me.
Try this; ensure there is no screen protector over the selfie camera. Either cut out/relief that area, use a precut V50S/G8X protector OR no protector at all. It worked for me.
Well this is most common issues with low level refurbs.
Please use this App - it will fix the issue.
