I've been getting a weird issue with my proximity sensor on my Note 4. It becomes... I suppose you could call it 'overzealous.' Even when not in a call, waving your finger over it will turn off the screen, no matter what screen it's on, home, lock, a game, Chrome, etc. And it's not just COVERING the sensor, it projects out to just over an inch away from the glass, so when I, say, go to pull down the notifications shade, the screen will turn off. It requires a restart to fix.
Anybody else had this particular issue?
You probably have some app what causing that because normally that sensor is only active during phone call. Possibly gesture control use that sensor too (when enabled). BTW proximity sensor in note 4 is set for 8 cm. It reads value above or below 8 cm but not exact distance.

I there any settings or something to adjust proximity sensor? I was trying to turn off screen covering sensor with thumb, but.. no effect.
Does it need any setting or my phone is faulty?
I noticed the same thing on my phone today.
The proximity sensor doesn't work if you've switched off the Automatically adjust backlight option in Settings>Sound & Display>Backlight. There doesn't seem to be any way around this as the proximity sensor doesn't have its own option.
Are you in a call? You need to be calling/receiving a call for it to work.
I agree, I think you need to be in a call for the proximity sensor to work properly.
For me it works fine. And i don´t hade automatic backlight on.

That's interesting because I can toggle my proximity sensor (whilst in a call) by toggling the automatic backlight. That option must be linked to something else as well.
Screen goes black
I do have the same behavior, when I make a call the phone's screen goes black automatically so if I need to press any key have to press send to get my screen back, then use the keypad, nonsense, is anyone having the same issue ?
for me, the proximity sensor doesn't work at all. I have the automatic backlight setting and yet it still doesn't work. any idea why?
SP300
I just found the solution, I have got the screen protector on "The Original HTC SP300" and is causing the screen to go blank when you do a phone call, If a remove it a little bit from the top left corner and make a call works as spec.
So I've always just accepted there was no lcd notification light.
Today I looked really close and I'm seeing 3 items. From left to right:
1. Proximity sensor (which works really well)
2. WHAT IS THIS?
2. Ambient light sensor
Or are two things used for one function?
1. Proximity sensor
2. Proximity sensor
3. Ambient light sensor.
A proximity sensor is two parts: an infra-red transmitter and a receiver. It measures the amount of light that bounces back to determine how close your face is.

Good to know, thanks.
Well, that was a short thread.

It doesn't look like a proximity sensor, it looks like a camera
Troll ....
I remember reading in a thread somewhere that the lights that are behind the soft keys are all individually lit (you can see it turns off the light of the key you push if you hold your phone sideways and look under your finger) and they were looking to create a code or app that will turn one of them into a notification light our a combination of them to specify different types of notifications.
wish I could remember if I even read it here or not.... Sounds like its doable and a viable alternative to an led, cept prob uses alot more battery
At least one of the three will light up. When I installed SIP Droid to connect to my VoIP server at the office, one of them lit up red as a connection error.
I don't know if it is the proximity sensor or not, but when I go outside my screen just turns off. Whether its in the boot animation or android fully loaded, it just turns off everytime I'm outside. Like the phone is oversensitive to daylight or something. Running cm7 latest nightly and I have tried other nightlies but same issue. Any ideas?

It's not the proximity sensor. Proximity sensor only works when the phone is in call.
You might have meant light sensor, but it can't turn off the screen.
Ok guys my question is this, when i have knockon enabled, if i am covering the proximity sensor, the screen does not turn on. So, am i right to assume that this phone has the proximity sensor always on when knock on is enabled?
That would also mean that using apps with pocket mode(meaning they use the proximity sensor to turn on the screen automatically when you remove the phone from pocket) would have absolutely no extra battery drain because the proximity sensor is already always on. Am i correct?
One of the big issues I have found, mainly with CM based ROMS, is that the option to prevent accidental unlocking seems to be missing/unavailable.
I've been testing various apps and utilities that monitor the proximity sensor, but there is one big issue - they monitor for screen on, but it seems in CM12.1 that the monitoring app doesn't work or get a screen on signal when you're using a lockscreen.
So the solution is not to check for screen on, but check for screen unlock.
I have a TASKER profile set up as follows:
If screen unlocked and proximity sensor on, then turn the screen off.
Works really simply. cover the proximity sensor with a bit of cloth or something and test it - if you double-tap the screen on, or it wakes due to a notification, the screen still goes on. But any subsequent action, eg slide to unlock or click on a notification, triggers the screen unlock flag, and this then checks to see if the proximity sensor is covered, and if it does, it turns the screen off again.
I CAN POST SCREENSHOTS IF ANYONE WANTS FURTHER INFO - BUT I'D SUGGEST GIVING TASKER A GO AND A PLAY ANYWAY, IT'S A BRILLIANT APP.
