[Q] Proximity Sensor Driving me nuts - Galaxy S 4 Q&A, Help & Troubleshooting

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

Problem with proximity sensor, screen still turns on during calls.

I use a BT headset so I dropped my phone back into the included pouch and then put it into my pockets, yet I suddenly hear key presses during a call! It seems that the proximity sensor sometimes have a problem where if I quickly take the phone away from my face and cover it again, the screen remains lit even when the sensor is covered. Is anyone else having this problem? Its even more annoying that leaving it inside the pouch would still cause this to happen!

to quickly reply, there is no solution of that problem today,
u can use soft like S2U2 or others to lock screen during a call

I have the same problem, the screen stays on while I am getting calls and stay off while making calls.

[Q] Screen crack and blackout after phone call

So my sister who also has an Aria dropper her phone and now there is a huge crack on the screen. She doesn't have insurance so she is trying to find an alternative way to fix it.
Simply replacing the screen would work, but another problem started happening when she cracked the screen. During a phone call, the screen will turn off, as it should, but when the call has ended, the screen stays off and the only way to turn it back on is to either pull out the battery and reboot the phone or to plug it into a charger.
Does anyone know how to solve this problem? Will replacing the screen fix the blackout issue? Or is this phone just trashed forever?
sounds like it destroyed the phone and the proximity sensor. i'm not sure if replacing the screen will fix this.
I actually had the exact same problem after dropping my phone during a call. I noticed that I didn't have to pull the battery to end the call if I held it up super-close to a really bright light (desk lamp, etc).
There were many times when I was on the street (in nyc), and had to find a bright light to hold it up to.
I dropped my Aria right on the corner with the ambient light sensor (in the upper right corner), which shattered the glass right in front of it.
Amazingly enough, after a few weeks, it started to get better and better - and now, nearly 4 months later (yea, i just deal with **** lol), it will hang up cals properly.
I'm actually working on replacing the screen right now, btw

Proximity sensor not registering movement/doesn't turn the screen back on

Hi,
Lately i have been noticing that the proximity sensor on calls on my s5 is not working properly. Once i answer/make a call, when i place the phone in my ear it shuts down the screen but the problem is when i take it away from my ear, the screen doesn't turn back on.
I tried the the testing menus (*#0*# or something like that) and when i placed my finger close to the sensor it detected, going green and vibrating but it doesn't go away from that state.
The only thing that changed was that i applied a glass screen protector a few days ago and im thinking it could be that, but its strange because its only when i back away from the screen that it doesn't register, so i don't know if that or not. Also, the protector is properly aligned and the edges are not on top of the sensor.
Anyone experienced this on their s5?

You have to change the proximity sensor or cancel it(cutting the flat)
I ended up removing the screen protector and it went back to working properly =/ I can't really put it back on now because it attracted specks of dust and it doesn't glue well now =/
Cutting it flat means it deactivate it? Because i find it useful for phone calls

Cutting it means deactivate fully, even in calls display stay on.

[QUESTION] S8 display randomly lights on and vibrates during call

Hi, anyone have issues with galaxy s8 when making/receiving calls ? My S8 was pre-ordered and on the first day of usage im faced with this issue, when making call or receiving phone randomly lights on display (once) and genlty randomly vibrates (as you press home button or nav button), then im take away phone from ear and put it back to ear display turns off, sometimes it keep turned off as normaly but sometimes it lights on again and vibrates, so i have to do previous steps or if ignore that issue than display turns off after some time and when im take away phone from ear to end call phone is locked and display won't light up until press lock button. Also im noticed that when im lock phone or even take it in hand (fingers touches both curved sides of display) phone also gently vibrates and turns from AOD to lock screen, this issue is also randomly. Some times AOD screen suddenly goes bright and than fades like it should be. After two weeks of chatting with samsung and store support im was send it to "service", they tested phone and after 10 days im received phone with status "no problems detected, software reflashed" but issues still not gone. And im can't replace it with new one because store refuses to replace it and says that they don't replace devices with software issues. Now im stuck and don't know what to do.
P.S. in *#0*# menu proximity sensor ADC values randomly keep changing even if nothing is in front of sensor, values are between 79-125 and when completely put finger on sensor values is 16368
Same issue here. Not sure why.
same for me too, international dual sim version s8
I have little bit different issue related to light sensor. My phone doesn't turn off the screen and locks in a pocket or if I close light screen by hands.

I have the same issue (also the oversensitive home button issue too).
I have a similar issue. But my screen never lights up. Neither during a call or when on the desk, for example. But during calls it sometimes vibrates as if I hard pressed the home button even though the screen is still off and I haven't pressed anything with my face, nor have I received any notifications. It doesn't seem to happen once every minute either (some phones notify you of every passing mine during a call).
It's not a big deal for me, just kind of curiously annoying.

Check in settings on ambient display, pocket mode, etc. Or maybe a cache wipe and reboot will solve.
Like Settings-Display-Screen Mode
-Keep screen turned on/off
Thanks to Samsung and Consumer Rights Protection Centre, together we forced store to replace phone. It was a factory deffect, so anyone who has similar problem im advice to replace phone.

Please help! How can I keep screen on during call?

So I broke the screen. replaced it and it worked fine. However i noticed the adhesive wasnt holding it tight enough. so after a few days I pulled the glass up as munch as I could and used some superglue on the top and then clamped down to hold in place. Now no more light is coming through but.. When I make a call as soon as a i press dial the screen turns back regardless of my distance to prox sensor. I'm assuming I got glue on it or broke it.
Eventually I will replace LCD but in the meantime is there any way to simply have the screen stay on during callsly ap?
I tried a few apps which did nothing. I looked for settings but nothing jumped out at me. I swear I have done this before on either an iphone or a much older android device.
Any suggestions would be great appreciated. Right now by using switches under accessibility im able to hang up at last but I cant turn on speaker and not sure how to set that up. So if there isnt a way to keep the display on any suggestions on how to set up so I can hang up and turn on speaker phone in the most effiecient way?
Its gotta be built in the system to keep the display on during calls but maybe not.
Again thanks!

There used to be an Xposed module to disable the proximity sensor on some SoC... But it is VERY SoC dependent from what I understand... And it may not be supported anymore...
Your other alternative would be to disable the proximity sensor in the kernel... I know it CAN be done... But I have no idea how
