Hey guys, I recently replaced my screen and its all working perfectly except for the proximity sensor. I replaced the screen with a white one so I don't know if that's why its acting funky, but no matter what app to test it I use, it never shows any values for the prox sensor. This leads me to believe its always in the 'on' state, so that when I make a call the screen instantly goes black (thinking that my face is up to it) and doesn't come back on until the call ends. I was just wondering if anyone came across how to fix this maybe with a kernel setting or app, just so I don't have to worry about it anymore.
Thanks for anyone's help in advance!!

Well just in case anyone runs into this problem again, here's how to fix it. After I tried to take it apart again and add scotch tape colored with black sharpie, it didn't seem to do anything. So I went and looked for an app that can do it, and I found 'Rezound proximity sensor calibrator' it allows you to set the threshold of how close an object is to the sensor and will tell you if its triggered (near) or not triggered, (far). Just trial and error the settings until it changes state and test the sensor with a phone call!

When I'm in a call and put the phone to my ear the screen does not turn off instantly. Only after the screen timeout period has reached does the screen goes off. Is this normal?
Hello, and sorry for my english, i have the similar issue, when i put the phone on my ear the screen continue on, only in a few second appear lock the screen. I have another issue: the ambient senson, in darkness and sun light the automatic brightness doesn't change the bright of the screen, only when i enter to the brightness settings and change the bright automatic off and on go right, i believe that is problem of the firmware, my firmware version is the spanish vodafone version. Can i change to the generic firmware via Sonyericsson Update Service software??

I don't think the proximity sensor would switch off your screen instantly. It will ignore all touches to the screen so you wouldn't touch something by mistake. The screen will be off later. Can test it with your fingers on the sensor during a call.

I did that. If the sensor is blocked with my finger or ear the touch can't be used. But the screen turns off quite a bit later than that. I think it's the same screen off settings that you use normally when the phone is unlocked and you don't lock it.
I've notice that my sensor doesn't seem to work. Under the brightness option if I check the "Adjust automatically" the screen still does not adjust the brightness. Also noticed the screen goes dark a minute in on a call, when I move it from my head it does not go bright. Sometime I have to unlock screen if call is longer than a few minutes.
Yep normally proximity sensors (on Nokia, iPhones..etc) turn off the screen immediately when ur face is close. Some examples:

Yeah, that's true. But I know that mine works! It's just not turning off the screen. Don't really know if it's supposed to do that though. But I think so!
Just spoke to vodafone and they are sending me a replacement tomorrow.I doubt that will sort the problem. But its worth s try!

The Proximity sensor works fine. However it works differently from what you would expect:
-When making a phone call the sensor detects your big head and locks the screen (put your finger near the sensor to try it, you won't be able to push any buttons on the screen).
-It only locks the screen. The screen turns off after some time.
-When the screen is off during a call and you remove your head (or finger) from the sensor the display turns on again.
Works fine for me! Don't kill SE because they do it differently then other manufactures, it works just fine.
Well I wish I could disable the proximity sensor right now.
I am trying to make a call without my big head bloking the proximity sensor, as I need to dial a number get trough the switchboard. (right now its lying flat on my desk while I am dialing.. So no head at all, just roof)
and the screen is still locked so I cant press the number 1.
The strange thing it worked when I called SE support, but it doesnt work now.
But right now when I need it, it does not work.

That is indeed strange. I've just tested it several times:
Make a call> Let the screen turn off>remove from my big head>screen turns on >screen is unlocked and I can acces the 'dialer'.
Well as I wrote, sometimes I can do it sometimes I can't.
I will try to clean the proximity sensor (right side of the Sony Ericsson logo)
the next time it happens. Maybe its to over sensitive.
Right now it works to the same number I was trying earlier..

Is it right to assume that the auto brightness is controlled by the proximity sensor. When I change my screen brightness to auto. It goes dull and stays dull.

I think that's another sensor actually.
If i have my phone in sleep mode, and pass my hand across the screen without touching it - it awakens to the lock-screen sometimes.
Is this usual behaviour? Is there a setting to stop this, or is the phone extremely sensitive?
Thanks.

Touching the screen shouldn't wake up the phone, even if you intentionally touches it.
Maybe you have some proximity sensor controled apps running, don't you ?
Do this test: Try to swipe your hand across the screen, far away from the proximity sensor and see if this happens.
If not, now try the opposite.
Does it take a screen shot when this happens?

if you mean that screen automatically turns on without doing anything, then it refers to a recent buggy installed app.
Could be caused by apps that you installed. Try identify the apps 1st.

I find this when there is a strong breeze across the phone...
Read this somewhere it seems it maybe to do with static discharge. Dunno how true it is it doesn't happen to me. Are you Raiden by any chance?

I'm currently using the latest version of clean rom. Lately I have noticed that sometimes when I grab my phone without waking it up, there is kind of a light that comes on towards the top of the screen and it displays missed calls and missed texts the light stays on for a few seconds then fades away by itself. What makes this wierd is I have not been able to force this to happen and sometimes it does it and sometimes it doesnt. This happens prior to me waking up the phone when the screen is black. I think it might have something to do with a motion sensor. Any ideas on what feature this is.

It's called QuickGlance and can be found under Settings --> Motion. The way to activate it is to reach for your phone while it lies flat, covering the sensors in the top-right corner, you can pull your hand back and it'll show up. Interesting thing, if you use an app that forces auto-rotation, such as rotation locker or what have you, you can get the QuickGlance screen to show up in landscape.
hi all
i have spent almost 2 days for an answer , no luck
my problem is
my phone s3 lte . screen turns of as soon as i obstruct the front camera and the 2 sensors area . it was ok before , since few days it started doing this . now i cant take screen shot pictures by moving my palm across the screen for example , not sure what this is due to
any help please .?
You've posted in the wrong section, questions go in q&a section -those for the i9305 stand more chance of a reply that won't brick your phone in the special q&a for LTE phones.
Report your own post and ask for it to be moved.
Having said all that, you've probably got a corrupt framework or a hardware fault. Flash a fresh official stock rom after a factory reset to test. If it's still the same then send for repair.
Is this when in a call sorry to ask noob question just curious if your covering the proximity sensor

Screen Blanks out on Galaxy tab
I ran this test and your screen is only supposed to change color from white to green during the test. My screen blanks out completely during the test.
Not sure if the sensor is bad or if it is a software or and OS issue yet.

Need advice.
I just received a SM-T705Y, KitKat. When I am in only some applications not all, the screen shuts completely off when my finger passes over the two sensors/camera near the word "SAMSUNG" at the top of the device. I have tested the cause and done it repeatedly by putting a small piece of black electrical tape on the sensor.
With the tape on the sensor, the screen never shuts off. The screen then will come back on several seconds after I remove my finger/tape from the sensor. Also, I do not have to actually touch the sensor to get the screen to turn off. But it activates the lock screen when it does turn off. ANNOYING !!!
My SM-T705Y is not rooted. It is in developer mode.
I think its the sensor that turns the screen off when you take a phone call is still stuck on ???
I have the phone proximity sensor turned off in: Settings> When I'm the phone screen The screen stays on.
Auto adjust screen tone : ON
Auto brightness is off
I have the "Smart Stay" turned off in: Settings>Device>Display.
Screen timeout set to 10 minutes. Screen mode set to "AMOLED Cinema"
I have restarted, not rebooted the SM-T705Y

The proximity sensor is located there. That's why you have that issue. It's normal behaviour.
If you are trying to turn the screen off during calls there is an option to do so in either calls settings or display settings.
If you move the phone away from your head it will turn the screen on. It's a proximity sensor, thats its job!.

Fix
I have same problem with my samsung and I fix it!
Just close all recently used app (press button next to menu button and close all) and you will have normal screen..... Looks like some app, especially call app make problem and activating proximity sensor. So one more time close all recently used app, press button next to menu button and close all app....
Good Luck!

Hi,
I've just had my screen replaced on the LG G5. However, post screen replacement I am facing the following problems:
- As soon as I dial a number the screen goes black and locks itself. I need to press the button at the back to unlock the screen.
- If i make a call using whatsapp, as soon as I hit dial the screen locks itself
I checked and it looks like my proximity sensor is not working. In the apps that I use to test it, it either just reads '0" for the proximity sensor or "NEAR".
Anyone else faced similar issues or have a solution?
I just had my screen/frame replaced and am having the same problem. Tap to wake rarely works and while making a call the display stays on while phone is to my ear. Did you find a fix?
I fixed my problem doing some Googling. I can't post the link to the thread but Google "LG G5 Proximity Sensor Reddit mobile repair".
"I had a similar problem. I replaced my display/frame myself and the tap to wake function rarely worked and the phone display would stay lit when held to my ear. Following the advice here, I found that there was a rubber grommet around the prox sensor window on the old screen that I hadn't transferred over. It's very hard to see and almost looks like it is molded into the frame. I dug it out with some tweezers and transferred it over and it is back to normal."
