Prox Sensor - EVO 4G Q&A, Help & Troubleshooting

Hey everyone!
My phone just started doing this today: During a phone call, screen shuts off when phone gets close to my face, as intended. But it doesn't turn back on when I pull it away. I usually have to pull the battery.
Downloaded an app to test the prox sensor. It shows a change when i put my hand it front of it, but never changes state when I move it away.
Any idea what could be causing this / possible fixes?

Proximity sensor and phone

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?

[Q] Phone Call Proximity Sensor

Noticed recently that When a phone call is in progress, the screen will go black no matter what and to get it to come back i have to manual hit the top power button.
I first noticed it with energy rom. When autobacklight was enabled, their was no getting back to screen at all. Disabling autobacklight at least allowed me to get the screen back after clicking the power button.
I switched to core cell rom and noticed the same issue, however, i can manually turn the screen on again even if autobacklight is enabled.
I have no further problems with the proximity sensor, just this one.
Is their perhaps some sort of proximity app that i could use to diagnose whether this is a hardware problem or software problem?
Ok, I had a similar issue, where the phone screen would turn off as soon as the "send" button was pressed, and the only way to turn it back on was either hanging up, or waiting till it felt like coming back on.
My proximity sensor was stuck "on". I could see the sensor status in the registry (don't remember offhand the reg entry, but it's a live reading of the sensor, 1 or 0). I installed "Proximity Sensor for Screen Off v0.2" from http://forum.xda-developers.com/showthread.php?t=624206
That was a mistake on my part, though... then the screen wouldn't come back on! It took some real finagling to get the screen on.
To fix it (temporary? permanent? dunno...) I waved a small neodymium magnet over the sensor (near the ear speaker). I have no clue why that worked. I don't know why it stopped. I *definitely* don't know if that's the issue you are having. But it's worth a shot
I've never had this issue after many different iterations of the Energy ROM.
Do you run Task29 when you flash ROMs?
Yeah i always task29. I don't believe it is the rom since i have tried another rom and the problem persisted. I tried the magnet idea but it didn't work. It was a refrigerator magnet though so i didn't expect it to. Anything else that requires the prox. sensor to work, has no problems and that is why this is weird to me.

[Q] Disable proximity sensor/Button to wake up screen

Hey guys.
I have a desire which has been dropped and the screen in the top left corner cracked. The proximity sensor is damaged, and I can test with various apps that this is indeed broken.
Now, when I get or make a call, the screen turns off, but since the proximity sensor isn't working, it's not turning on again when I move the phone away from my ear. So I wanted to know if anyone knew of a way of either completely disabling the feature, or a way of manually "waking" the screen again, by using any of the hard-buttons?
Thanks
what happens.. when you press power button
Sometimes it comes on, but mostly it doesn't... Regardless of which button I press...
I have read somwhere.. that by blowing some air over that part.. may clear any blocakge.. and proximity sensor works fine.. just try this .. use any vaccume cleaner.. and blow some air over sensor part..
And if that doesnt work.. search for this app in market "'Proximity Screen Off' ".. it might help you.
Yeah, I read that too... Tried blowing with compressed air even. The sensor is dead :/
Try this app.. it will switch your proximity sesor off after call ended.. its not mine just found. you might wanna try this

Hy, i have got the same problem !

Problems with Pixel 2XL detecting my face against it on a call.

Is anyone else having issues recently with their pixel 2XL being able to detect their face against it on a call.
Sometimes I'll be on a call and feel my phone vibrate and when I peek at the screen, I can see the screen is on and it's on a random page like my alarm settings, because my cheek pushed against a button on the home screen for example.
Also, when pulling the unit away from my face sometimes the unit doesn't light back up and i have to push the physical on button to get it to turn on.
Or even worse this week, I've noticed that after my phone doesn't light back up when I pull it away from my face and I try to turn it back on with the on button, it doesn't work... the screen never turns back on, I have to double push the button to get the camera to pop up and then dismiss it to get back to the home screen.
It's getting pretty frustrating. Has anyone had this issue? Anything I can look into to fix this?
I`ve been having this random issues with the proximity sensor and my phone not able to charge with the stock charger.
The proximity sensor is right by the ear piece so if you have your ear touching first it should, in theory, turn off the screen before your cheek touches the screen. Personally, I don't have my cheek touching at all while on a call but I have a slim face.

Download a sensor test app and check for proximity sensor. I had a similar issue some time back. Reboot fixed it for me.

Samsung Smart Stay kept my screen awake, sometimes....

I noticed that when I turn on Smart Stay, I get this weird bug whereby when I rest my phone on the table face up after using it on my pc table, it just never turns the screen off.
Until I pick it up again, swipe or let it look at my face for a while and put it back on the table, then it will turn off again, as it should.
Does anybody else experience this?
