So I just happened to notice that the sensor blinks on and off rapidly because I was using my webcams mirror mode and saw it flashing (invisible to the human eye). I cant help but wonder why on earth it is active while the screen is locked? Any thoughts? Or anybody actually know why?
Because it is used as a proximity sensor: the phone senses when it is in your pocket or not so it can change the ring tone volume. I think it is also used as a "mute" sensor when you lay your phone screen down on the table but I am not sure of that.

I've been wondering, would it be possible to make an app that kicks in when you're on a call, that uses the light sensor as a proximity sensor.
The basic idea is, you put the phone to your ear, it blocks light and the screen locks, take it away from your ear, it detects more light, and unlocks the screen so you can enter numbers etc.
I was also thinking instead of being set at specific light levels (less than 50 for off, over 50 for on etc) it could work on a factor of relative brightness, so if it gets 5 times brighter it knows to unlock the screen.
Does this sound possible?
I don't think this can work. What happens during the night?
very old idea
phone must have bio sensor near speaker which touch to ear, so only hardware solving
using light sensor will work only with light, at dark place\time it doesnt work
another way is to make sensitive top of sensor display for touching but other part of display must be blocked
deadend
Tha X1 speaker is right next to the earpice, it's almost part of it, that's why gave me the idea.+As for dark places, that's why I suggested it measures a differennce in brightness, rather than specific values. Obviously at a certain point, it won't detect any change, I guess then the programdetect darkness up until the point of answering the call, and disable itself.
Or maybe there's a way to use the backlight to create a lightsource but have the touch part off...
Brightness would increase as the phone approached the ear, then drop off as it got there, then similar when you take it away.
Actually, based on the intention, I think it would be sufficient if the phone app is active, the screen is on and locked if phone app is inactive. Touching cheeks, etc are all not real problems in my opinion.
xperia tweak
xperiatweak will fix this issue.
I've got a problem that when I phone my screen goes blank without waiting me to put it against my face and then doesn't come back on again without me having to push the power button.
Any ideas where to start looking. I'm using the standard stock 6.5 WWE ROM.
I believe it uses the ambient light sensor on the front of the device to determine when it is against your face. Make sure the sensor is clean and not hidden under an aftermarket case. The TP2 might also use the accelerometer to determine the orientation of the device, in order to complement the light sensor and better determine when you're holding it up against your face.
So I'd go into the settings and calibrate the G-Sensor as well.
Thanks will take a look at that.
Having an Issue with Proximity Sensor (Can only talk on phone with Keyboard extended)
I am having a proximity sensor issue with my Tilt 2. When the proximity sensor kicks in and the screen goes black, the person i am calling doesnt hear my voice. Only when I move the phone away from my ear or extend the keypad so the 'lights stay on' does the other person hear my voice.
What can i do to force the light to stay on even when its up to my face.
where is this sensor located on the front of the phone? I am wondering if my screen protector is causing it. I have no clue
Helo,
Same problem here.
Any help?
Hi pals!
I've been surfing this site for long time. I've had a lot of fun with all the different applications in here and now I've got a request.
I've found some applications for proximity sensor, I've seen those that turn off the screen when detect proximity. But I haven't found the one that turns on the screen once it detects the proximity again.
I'd like to put my Leo on the table and pass my hand in front of the sensor to turn the screen off and pass it once more to turn it on.
Anyone?
When i am on a call 6 times out of 10 my fat cheek hangs up on the other person haha
Is there anyway to turn of the proximity sensor or adjust setting??

There is an app for configuring your proximity sensor, but you need root for that... The solution that works for me is to just move the phone a bit towards your face while talking so that the proximity sensor(the thingy that looks like a led next to your speaker grill, across from the real notification led) actually touches my ear, than the screen turns off...
Hi guys
Since one day , my screen turns dark when having phone call or receiving phone call.
I can't type the keyboard and press the speaker button, which are inconvenient.
I have updated fw to fw_capricorn_miui_MI5S_V9.6.1.0.NAGCNFD_857fde8b41_7.0.zip
I have this issue on different roms including lineage 14 , lineage15, RR,and pixel experience .
Do anyone also have the issue and do anyone know how to solve it.?
My phone drop to ground once which cause screen crack. I am not sure whether this is the root cause.
Many thanks
The phone has on the front a proximity sensor, which is basically a small light sensor that checks if the phone is near the head or not. If it's near the head, it turns the screen of, so that you don't press any buttons while holding the phone to your ear.
I think either your sensor is broken or the crack always brings light to the sensor.

Could I disable this function?
Always disable light sensor or disable when have phone call
I had the same problem I thought the sensor was broken (you can test it with sensors test https://play.google.com/store/apps/details?id=asd.vector.sensor ). But it was ok, it turns out it was firmware related. When I downgraded my firmware the proximity sensor was working again...
Good Luck
