Hello!
Today, I tried to solve a problem with proximity sensor in my G2, which did not work at all. When calling and putting the phone to my ear, the screen didn't turn off, resulting in a lot of accidentaly declined calls. I assumed it was because the inner piece of glass in front of the sensor was dirty and foggy, so I used a tutorial (/watch?v=hPFBA24dR1w) to disassemble the phone and clean the sensor.
At first I discovered that the front LED and proximity sensor hadn't been plugged in, so I fixed that and tried to turn on my phone. This fixed my LED, which I thought was broken for a long time, however didn't fix the proximity sensor.
So I went back into the internals, disassembled the phone completely and cleaned the glass in front of the proximity sensor. Then I plugged all the cables back in. However, when trying to power the phone back on, the screen doesn't turn on.
The blue LED is flashing during the startup, and after several seconds the back notification starts flashing too. When holding the power button, the phone vibrates normally, so the phone seems to be working fine, except for the screen.
I went back to check all the cables, which seem to be connected fine (I can send a photo if needed). I noticed that when I press the power button, I can see some light through tiny holes in the back. Then I noticed the screen turns to a bit lighter shade of black when powered on. I assume the touch screen is working too, because when I try to double tap the screen, the front LED flashes.
I'd like to ask for your help. Is there anything I can try right now?
Thank you very much, and sorry for the long post.

I've been having a really strange issue with my barely two month old Galaxy Note 3. The proximity sensor has been acting really strange lately - it can easily detect when it is being covered, but can't detect when it isn't. Say I am in the middle of a call and I put my phone up to my ear... the screen turns off. If I remove the phone from my ear, it stays off, and won't turn back on unless I hit a physical button. This just started happening, and I have no idea what is causing it. I used a test app and it claims I am 0cm away from the phone (even though it's on the table and I'm at least a foot away). I tried cleaning the sensor, but that didn't do anything. I do have a screen protector, but it is at least a centimeter below the proximity sensor. Air view still works fine. The phone is rooted with Root De La Vega, and I had Wanam Exposed, but I removed it in hopes of fixing the problem. Also, I'm pretty sure there use to be a tiny blue led that checked the proximity, but it doesn't appear to be there anymore (I don't see it turn on). I really don't know what to do, should I RMA the device?
Hey
My proximity sensor keeps stuffing up. When I make a call, and put the phone to my ear , it turns off the screen but when I release the phone from my ear, the phone screens remains off and I cannot access the phone untill the other party hangs up
This is a real pain when they do not answer and their voicemail comes on and I need to leave a message. I have to turn off my phone when this happens
I have fixed this but it only remains fixed for about a day
I have cleaned it, blown in the area where the proximity sensor sits with a straw ( did not have air compressor can) worked for about a couple of days then it stuffs up again
Not sure what the hell I can do to fix it now.. Buy a new sensor? I have a screen protector but there is a cut out where the ear goes
Go into settings, accessibility, then tick 'The power key ends calls' It won't turn off the screen.
I had that problem, I took the sensor out and wiped it, seems to be fine now. I saw a video online to help me, not got the link readily at hand though
I have replaced the screen, LCD and frame on my VS980 due to dead sections of the screen. There were no problems swapping everything over to the new frame. The phone seemed to be working perfectly until I went into a dark room. When I am in a room with little to no light knock on does not work and if I press the power button the screen times out while I am swiping the home screen. Which component will cause this problem? I double checked each piece before reassembly and everything appeared to be properly installed.
Have you tried the motion sensor calibration? For me i press the power and volume down button quickly and it unlocks. Have you update the touch firmware?
I did the motion sensor calibration and it didn't help. the dialer codes I have found for the vs980 don't get me into the service menu.
I dont know for sure but i think its the hardware problem as in replacing the new LCD and all, but ya that be expensive to buy new ones just after buying a new one. If it still have warranty maybe replacing it perhaps. If the service menu dont work, i dunno.
Your proximity sensor may not be plugged in all the way.
How does the phone work while making a call?
Test it first. If the screen stays on during a call while the phone is held to your face, open it back up and double check all connections.
Unplug and replug the screen, digitizer connections, selfie cam and proxy sensor connections then test again.
The proximity sensor which is top left when looking at the front display. Smush and/or rub with your finger, then try to unlock again. I have to do this frequently.

I want my second screen to be on when the main screen is off. Second screen works fine when main screen is on. When I turn off the main screen, the second screen changes for a split second (you know how it changes to signature/time?) and then goes black. BUT it still works. From memory, I can swipe to quick toggles and turn on/off my flashlight and it works. But the second screen stays black.
This started after I replaced my cracked screen. After swapping it with a replacement, I was having a bunch of issues with the proximity sensor (second screen off when main is off, knock on wouldn't work, fingerprint wouldn't work, sensor app always said 0cm). I fixed these by moving over the little rubber gasket from my old screen, but the second screen still doesn’t work.
Second screen daily timeout is disabled. I wiped dalvik/cache from recovery. Rebooted multiple times. Opened it back up and reconnected the display ribbon cable. Tested the display and sensors from the hidden service menu.
Any advice?? I'd like to troubleshoot further before doing a hard reset (I have so many mods installed lol). This second screen is why I haven't upgraded the phone yet...
You forgot to put the rubber gasket for the proximity sensor back in. Without it, you'll see exactly the problems you are now. Search eBay for LG V20 Rubber Gasket Holder and you'll see the part I'm talking about. If you put it back in it will fix these issues. It's a common problem with the LG V20 screen repair.

Hello guys,
I've got a problem, starting yesterday, my Samsung S10 Plus (G975F on ASJG firmware) has some touch screen issues and proximity sensor issues.
What is happening is that when I start a call and I place my phone near ear, it turns the screen off, but when I move it from my ear, it stays off. This issue started yesterday.
I removed the screen protector, did factory reset via ODIN (flashed clean firmware with factory reset).
The test on star#77692# works (proxy sensor test), when I place my finger it turns on, when I lift it it turns off.
Thank you for your help!
perhaps try cleaning the screen. I hear there is a number you can dial to run system tests but I am not sure if it.

Just to finish the thread.
I had to replace the screen due to the fact a brand new phone (3 months old) had its display unglued somehow and the issues I described started to appear.
Now everything works...huge dissapointment in Samsung screen quality.
