    It's the sensor for the air gestures and what not, if you turn them all of and look at it, it won't be there. Atleast that is the case for mine.

    The sensors to the right if the earpiece are supposed to be a proximity sensor, which shuts off the display and touch screen when you're on the phone.

    I don't think they blink, though. Are you sure that your not just seeing the status LED in the dark?

    When charging, a red led turns on and then turns green when fully charged. Maybe that it the red light you are seeing.

    The red light on the front of the phone near the top-left?

    That's the low-battery/battery charging LED.

    It turns GREEN when fully charged and blinks BLUE if you have any notifications. If your battery is low, it'll blink RED. It'll stay solid RED when charging until it's fully charged also.

    I'm not talking about the LED light on the left. talking about the 1st sensor on the right of the ear piece.

    I notice you are in Ultra Power Savings in that image and with 92% battery charge your image shows only 1.7 days left on standby. Mine is at 94% and shows 11.70 days left on standby.

    Something is wrong aside from that led light in the upper right. Call your carrier or Samsung tech support.

    I agree. But that light from the proximity sensor is worrying me. I know one of those holes is an IR EMITTER, and the other is an IR RECEIVER. But the key is that it's infrared. You shouldn't be able to see it at all. Perhaps you have superhuman vision? :-D

    I have had my s5 for a few months and only just noticed the same thing tonight. I have no idea why it suddenly came on and it doesn't seem to turn off. Has anyone figured out what the light is and what it's for?

    I just tried shutting down my phone and re starting it which got rid of the red light.

    Hi everyone.
    I think I know the solution. It is the proximity sensor and that feint red light should be there and it means that you have something on like Air Gestures etc. I am getting an S5 soon but even on my S3 it comes on when making calls cause as you know when you are calling, the screen goes off near your ear. It's perfectly fine and you shouldn't be worried. If you want to check what I am saying, just switch off ALL Air Gestures etc. and it should go off.

    I have been noticing the same thing the past couple weeks and it is never when I am talking on the phone. It randomly comes on and then sometimes flashes. Then it goes away after a long time and I'll notice it's on again.

    Did any one actually figure out what this is? Mine has the red dot on all the time regardless of whether air gestures are on or not. My husbands Galaxy s5 also has the red dot and he never has air gestures on. The red light has been on since I bought the phone in April.

    Hello,
    I have managed to turn de red light on from the sensor on an Galaxy S4.This is how I done it.I have called from another phone the S4 and answered.While in call, minimised the call and opened gallery and tapped on a random picture.After tapping the picture the red light is on and you can also make gestures while in call.If you turn the gestures off the light is no loger there, but the in call screen work on and off like it should.The same thing is with my S5.There also are some infrared sensors that you can see slight red in the dark coming out of them.

    That happens on mine when I'm in contacts or in a text message but that is because I have the "direct call" feature enabled which is the thing that will call the contact currently displayed. The proximity sensor turns on to see if I put the phone to my face

    I have none of these options on in the first place and I double checked, the light remains.

    I really don't care about the light being on, I just want to know why it's on......my curiosity kills. -.-

    It could very well be the infrared sensor. Xbox one has a bunch that shine red and appear to blink when you move your head. If you grab another smartphone or a digital camera, go in dark room with minimal light. Point the camera at your device. If you see a purple beam on the screen from this red light than it is your IR sensor. Make sure to point the red light directly into camera.

    after 3 weeks, i finally solved this.

    PROXIMITY SENSOR LIGHT IS NOT SUPPOSED TO BE ON ALL THE TIME. that just drains ur battery

    So I took my galaxy s5 for repairs and the idiots flashed it with a different stock. Got home and this annoying proximity sensor just wont quit. Blinking, blinking. Restart didnt work. No viber installed. All air gestures off. I noticed that after restart it will stay off but comes on after i make a call. I knew this was not normal behaviour since it worked ok before the repair, same settings, same apps.

    Solution is that u have an app running that is using air gestures. U need to find it. For me it was an ir remote app that had the air gestures feature on. Dont know why it wasnt on before.

    this is what i did
    1. Make sure the proximity sensor is blinking like it is not supposed to do.
    2. Go to app manager
    3. Check running apps
    4. Stop the apps one by one and see if the red light goes off. Check light after each stop. Try non-native apps

    *******Death to the proximity sensor light****

    I think that red light is a camera to spy on people. ..lol

    The IR emitter-receiver (commonly referred to as an "IR Blaster") is actually on the top/edge of the phone, where the earphone jack is. The only light on the top/face of the phone is the notification LED. This does flash discreetly unless you have it turned of in all notifications.

    Has anyone seen the updated app permissions for fb and think it might have something to do with that? I have the same problem and Im just throwing ideas out here, but fb and messenger (the app) have permission to record and use your cameras whenever they like...might be why my battery always seems to be dying so quickly..

    Default Re: Anyone else notice " red light " in sensor on S5?

    The IR- blaster is located at the top of phone next to the mic same corner as the headphone jack. Then there is the LED notification light, proximity sensor, ambient light sensor, and front facing camera. The faint red light you are seeing is coming from the proximity sensor. If you have gestures on then that light will most likely be on. If you don't have gestures enabled but still see the light then some other app is using the proximity sensor(which is taking up precious battery life). You have to go to the application manager and force close suspected apps one by one to find the culprit. 😀

    Fb needs to get their **** together lol. Their both so slow on my s5 and have way too many permissions... Although I think the camera permission is for fb to access the camera when we want to take a picture thru msnger.
