[Q] Red LED problem in Galaxy R - Samsung Galaxy R i9103

My Galaxy R is running on a Omni ROM based on Kitkat. I have noticed that when the screen is off the red LED beside the speaker at the top, turns on and when the screen is on, it goes off. I didn't notice any such change when my GR was on stock ROM.
Is it normal? or does this denotes that something serious? will it affect the battery life?
and lastly....
Is there a way to turn this LED off?
Kindly help.

It's the proximity sensor, it must be turned on on stock too when you have a call.

But it turns on as soon as we turn off screen too and remains on until we unlock screen.

[Q] Light sensor, how to disable it?

how to disable light sensor for optimus 3d?
You mean the light sensor that controls the brightness of your screen or the light sensor that detects when you are in a call and turns off the screen?
I'm pretty sure you can disable the first one by just turning off Auto Brightness. The second one can't be disabled as far as I know.

Well, I was also wondering because when you turn the phone in talking position but away from your ear the screen is still on, when you get close to the ear the screen get off right away...
Can you change the delay on the proximity sensor at all? When I move the phone away from my head it takes a good few seconds for the screen to come back on meaning it takes me about 5-6 seconds at least before I can hit the end call button.

When i'm in a call the screen gets black and just turn on when the call is over

I can't get screen on .. I press off/on button butt doesnt work...Anyone can fix this ?

you're infront of the ligth sensor, between the LG logo and the front-camera. get ouf of there xD
This is perfectly normal behaviour. The screen turns off to prevent your ear from accidentally pressing any of the buttons on screen. When the call ends, bring you phone away from your ear and the proximity sensor will turn your screen back on automatically. If you want the screen to turn on in the middle of the call, just bring it away from your ear. It takes a second or two for the screen to turn back on.
My P920 doesnt work that way ... i'm with gingerbread and when the call starts then the screen goes off and just turn on when the other person ends the call .... if I press the off/on button doesnt work even if i want to turn off the call i can't because the screen dont turn on
It does that on gb also

how can i desativate the sensors ? i have to take off the battery to the phone get back normally
did you cover the screen with some screen protector? they might cover the sensor as well. the sensor it between the front camera and the logo.
well i have download one app that check the sensor and my it's broken or isnt working( i'm with TaizGB) Anyone know how to desativate ?
Increase the minimum CPU speed in your ROM (it's probably set to 300mhz or lower). That will stop this bug from happening.

Flip case - screen off - Any sucess ?

One missing feature of our beloved note it the ability to turn the screen off when closing the cover over the screen.
Also proximity sensor is missing too..
However there are apps that make use of the light sensor to turn off the screen...
I have tested various apps including tasker, locale plugin, smart screen off and so on, which can make use of the light sensor to turn the screen off..
But I find that the light sensor itself is not very sensitive in low light conditions..
Even in a dimly lit room the sensor detects only 0 lux and forces the screen off... Bummer..
Anyone here sucessfully using case close screen off ???????

Ipad and few other devices like nexus 7 makes use of the magnet sensor.. THis is the best way to do it as there is no battery consumption.
Samsung may not have included this as the magnet might interfere with the s pen..

When I load up tasker, it allowed me to create a condition using the magnetic field state. But I'm new to the app and haven't figured out how to use it yet.

Red light near earpiece always on (CM11)

Can anyone help me?

Thats the proximity sensor. Try restarting the phone or make a call and use the sensor, it might turn off.

Red Light near Proximity sensor Always On

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?

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.
