My GF and I are very annoyed at this problem. When you tilt the phone on it's side, lik eholding it with your shoulder the phone will turn on. It just so happens that your phone's mute button will be on your cheek and we mute each other.
Is there anyway to stop this? Thank you guys in advance.
Are u sure u are not "uncovering" the light proximity sensor when u tilt it. Its very sensitive, and I have noticed it get turned on when the phone gets an inch or more away from ear exposing the light sensor to any form of light.
While on the phone with my girlfriend at night this happens a lot. Because it is so dark, any movement I do will cause the screen to turn on and I have to hit the button to turn it off.
Just try vto keep it glued to your face :/

Yeah I'm sure. The feature is suppose to be for when you set the phone on your desktop the screen will turn on so you can hit speaker or end the call.

Umm simple work around, get something opaque and stick it over the light sensor with something that won't leave a residue so you can take it off when your call is over?
obviously some people fail to understand how this works. there is a light sensor for screen brightness and a proximity sensor. it is the proximity sensor that detects your face and turns off the screen. the light sensor is not involved in this process. what is happening is that the i9000 roms have default android 2.2 settings that force the proximity sensor to be ignored in certain orientations, i dont know about the new att updates but the 2.1 roms had the overrided from samsung. i tried to fix it in tasker but tasker lacks the option to power off the screen, it can go to lock screen instead which may be acceptable for some. there may be a different way to do this in tasker but i need to experiment more.
there is no external workaround for this as it is not the proximity sensor being uncovered that causes most problems but the phones orientation. any workaround or fix must be done with software or a change in a file somewhere.
I am sorry, and have been humbled •_•

This is correct. In simple terms the orientation sensor takes presidence over the proximity sensor. So if you turn the phone on its back while on the phone, the screen will turn on.
There are no fixes for it that I'm aware of.
How abt keeping auto-rotation off all the time, and turning it on only when needed, as a work around?

It's not linked to auto-rotation unfortunately, Its just something that we have to live with.
Man... wish there could be one but sounds like there can't be.

Ever since my 4x HD was new I've noticed a problem, but it's getting so annoying now I finally thought I should do something about it, and I've contacted LG with a view to sending it off for repair:
When I remove the phone from my ear the proximity sensor usually fails to wake the screen back up, meaning I have no controls to end the call with. Occasionally swiping my finger over the sensors at the top of the screen wake it up, but mostly it takes several attempts, and presses of the screen lock button.
SO annoying when you are leaving someone a voicemail and it's still recording, all they hear at the end of the message is the muffled swipe of a finger and me muttering and swearing at the phone as it carries on recording for another 30 seconds or so!!
Anyone else have this issue??

Mine doesn't awake in the end of calls too... but I thought it was normal
We have an option where we can use "Power button" to turn off calls...
I didn't knew that the proximity sensor was suppose to wake up the disply...
Hi Rudeas,
Glad it's not just me!
Where is the option to use the power button to end calls?

Maybe a really daft question, but I presume you haven't put a screen protector on that covers the sensor? Stone of the cheap protectors do and that would stop it working properly.
Good thinking, but no, I don't have a.screen protector or anything over It.
To test and eventually to calibrate the proximity sensor, you can use hidden menu (dial 3845#*880#) -> Device Test -> All Auto Test Menu Full -> ALC / Proximity Test.
You can even test the "auto brightness mode" (to test also the light sensor) and "enable proximity wakeLock" (to simulate a call).
To test the sensor just put a finger near the sensor.
There is also a "Calibration" feature to calibrate the sensor if needed.

Wow italianquadcore! That is amazing! Firstly I could see by putting my finger over the sensor how poorly it was working. Often it wouldn't notice I had taken my finger away- then I pressed calibrate, and now it notices instantly, every time!!
Thanks loads, I'm assuming it's fixed now!

Italianquadcore is a lifesaver, right?

Thanx a lot, yah it was a screen protector giving trouble to sensor.
Hi everyone.
I've just bought myself P880 as well. But had the same problem as author. However, the fix to calibrate via hidden menu didn't help at all. My sensor doesn't react at all, however, when I am using a hardware test it shows sensor is present.
Do you think there is something wrong with sensor itself, or there might be some android might have failed to initialize driver?
Thanks in advance!
Mine wasn't fixed by the calibration for long. It soon got worse again, I actually damaged my headphone socket (using a really big headphone plug through an 3.5mm adapter, then accidentally knocking it) and ended up buying a new part from etradesupply.com for about £17. The headphone socket is the same component that contains the proximity sensor, so replacing that fixed it.
I had phoned LG, but as I had bought my p880 from german amazon they said they wouldn't have covered me even if it had been a warranty problem (So much for Europe being somehow unified!) so I had to risk taking my phone apart myself!

Using the hiddenmenu gives me an app crash on v20a when hitting device test, Any fix for that?

It works with V20A without any problems (just tested). Please check if you disabled something, regarding hidden menu or some other related items, in app management.
Thank you italianquadcore!
That solved my issue as well...
Is there such a code for CM?

Hi Guyz,
My friend dropped his nexus one on the floor and from then on he is facing a weird problem. When he receives a call, when the sensor is turned on, the screen never comes back and it remains black. The only option is to pull out the battery and i suppose the drop has made proximity sensor faulty. He is not a rooted user. Is there any menthod to disable proximity sensor without rooting ? If not how can i fix it after rooting ? Any build.prop changes ?
Thanks,
karthik

hey Karthikus , I know this is not a new post, I would like to know if you solved your friends's problem, I have exactly the same, I used a couple of apps to disable the proximity sensor but still no luck, by the way I have the cyanogen mod 7 in my nexus now. the phone is a beauty, but its kinda annoying to have to remove the battery after a few calls, also I'm using a bluetooth headset, wich kinda minimizes the problem, but still not happy. please let me know , or not, I'm planning to build a disable sensors app myself in case I can't fixit. oh, and I tried all the other solutions I could find in google, like cleaning the sensors, (I dismantled the phone already) and enabling other ways to bring the screen up using other methods like trackball press or menu press. no way, still there. so please let me know. if still relevant.
thank you.
my touchscreen got cracked and i had to install a new screen assembly and probably the new screen has some problem with proximity sensor or while installing the proximity sensor got covered by the adhesive finally the proximity sensor shows up as always ON. i want to disable this completely. so how do i do this in z1. iam using the new kitkat build. the gsm.proximity.enable=false in build.prop isnt working. hardware disabler app dosent scan anything in / directory. and ive tried using xprivacy to block phone app from accessing the sensors it wont work either..as soon as i make a call the screen goes off the only way to get my screen on is when the other caller hangs up and the call has completely ended.
someone help me plz
I gave my phone to the service center because the CPU got damaged along with the screen.
After that the proximity sensor doesn't work properly. Whenever I call someone it switches off the screen and I can't wake up the screen. I gotta wait for the other person to hung up the phone. I deleted my APDS9702 driver to disable the Proximity Sensor but still it dosen't work. Any solutions?
