Sometimes when I hold my phone in a way that covers the light sensor, the screen turns off. I'm guessing it's a feature like when you hold it up to your face to talk or something, but it can get extremely annoying when it misfires (which it does a lot).
Has anyone else had this issue? I have a white D801 on tmo.
Isn't this a feature of all phones so that you dont accidentally turn it on and dial while it's in your pocket?

Yeah, but it's only supposed to happen when you are calling someone. My G2 is turning off if I cover the ambient light sensor while on the homescreen.
I have just started noticing this on my Verizon G2 with clean rom. It seems to do it the most right after you turn on the screen.

Yup. I'm on stock and it happens the same. If you turn on the screen with your thumb over the sensor, it will turn off again quickly even if you try to unlock it.
When this happens it usually happens when you are in a hurry. Really annoying but the benefit is that this feature does keep the phone off when it is in your pocket knocking about.

Do you folks have the option enabled that turns the screen off if it doesn't detect your eyes on it? That may be the culprit when covering the sensors.

Anyone know how to prevent auto-locking/standby when talking on the phone?
The screen turns off when I'm talking, which I assume is from the light sensor, which is fine, but when I take the handset away from my ear it remains dark or is on lock.

I have the same problem since it was new. Sent it back for repair, and told nothing was wrong with it.
I uninstalled all my apps, but no improvement. shaking and tapping the phone makes the screen flash back on for half a second, but not long enough to press hang up or any keyboard numbers for automated answering systems.
I rooted the phone to see if I could get more control, but haven't found an answer yet.
first, where are you having this problem?
WinMo/Android
and second, it's not the light sensor, it's the proximity sensor.
This might seem like a dumb question, and I just got my MTS 2 days ago, so I'm still learning about it, but at the top of the phone, where the LEDs are, what is the function of the opposite side of where you hear your calls? Is it there for looks or does it have LEDs in there also?
it is the proximity sensor... it is what "locks" the screen so you are not activating it with your cheek while on the phone... it also blacks out the screen when you are on the phone
I've always wondered what this was too... thanks for that information.
it also turns the button lights and keyboard lights on/off at certain light levels...that way when its bright it turns the lights off and when ur in the dark the lights come on...i love it!

that seems to be incorrect because i use the headset and if i lift the phone to a certain angle the phone screen turns off, but when i tilt it back down it turns on again. i will look into this more but from what i have seen it is just there to be a little more symmetrical(would you want a phone with asymmetrical looks to it)

no hes right it IS a proximity sensor...go where theres some light and open the keyboard and see if the keylights are on...if so, try to make it brighter...(shine a flashlight at it or something) and the lights will go off...then put your finger over the sensor and the lights will come on...it works, try it...definitely not just for decoration...what you are experiencing is a perfectly normal effect of the proximity sensor doing what it does...no reason to look into it...
or download "Sensor List" from the market and look, it lists the prox. sensor and its data...put your finger over it and watch the output jump...
or run adb logcat and put your finger over it and itll come up with a entry about the light value changing...

without the headset try calling your voice-mail in a lit room and hold the phone away from you and move it all around an at different angles, you will see it makes no changes but just by putting your thumb over that spot it kills the screen and as soon as you remove your thumb it comes back on... might want to actually do some reading or testing before saying someone is wrong. not only would a quick 5 second test show that it is the light/proximity sensor, or you could try a quick google search
You can also have the left light flash for missed messages.
i was doing some testing and i am retracting my statement, you were correct wulf and i am sorry that i doubted this.
hey it's kewl we all make mistakes
Anyone else have proximity sensor issues on the G2? Ever since I got it, it's been very wonky, even when it was purely stock. The worst problem is often when I take the phone away from my ear it doesn't turn back on, and then it seems that the knock on sensor stops working, and I have to hit the power button. Sometimes when I put the phone to my ear when getting a call the phone goes to sleep and the call gets cut off.
I do have it set to automatically answer the phone when I raise it to my face, so maybe that's an issue. I'll disable that and see if it helps.
Anyone else? I'm kind of bummed as I use my phone as a phone first and having something like the proximity sensor work is absolutely crucial in my phone use.

I've noticed that everything works well with this. Surprisingly so. On the s3 i would always get the black screen issue when pulling away from my ear. Ringtone even lowers as i pick it up. I could never get that to work on my s3. Not that, that matters.

Yes, but not all the time. When it does happen, i can't get the screen to come back on at all until after the call ends. It doesn't do it on every call but when it does it's really bad.
I'm running tge Verzion Clean Rom right now but it did it on the unrooted stock too.
Sometimes I have to knock knock twice in a row to turn on the device. It works well turning off, but on half of the times it won't turn on. Gotta do it twice. Anyone else encounter this?

I do not have that issue, but I have read in a few posts that it can be dependent on where you are knocking on the screen.

I think the biggest issue is knock speed.... mine works damn near 100% when I slowed down some, and knock slower like it showes at the end of the G2 commercials....
I think it's partially related to the proximity sensor. There are times when I can't get the knock on to work at all and when I hit the power button the screen shuts right back off.
Usually a few swipes over the sensor makes it work again. Sometimes I'll go in and turn the Knock On gesture off and back on and then it seems to work great for a while too.

This is my exact problem. The phone just decides it doesn't want to wake up with knock-on...but after I press the power button, it only turns on for half a second and it's out again. I never tried swiping over the sensor, but hopefully it works because it's mighty annoying when it does it during a call!
I wonder if there's a fix for this?

this, if you are trying to do it like you did on the nokia n9 or nokia 8800 then it won't work
slow deliberate knocks are the only way
waiting on the g2 to arrive, but on my review unit, knock knock wouldn't respond correctly if i left the phone on the table, but if i picked it up, it would work nothing scientific here just an experience of one person and one prototype
I had the same issue... What fixed it is: 1. I found that the screen protector was hindering it somewhat. 2. Go to settings->display->screen-off effect-> and change it to simple. This REALLY seemed to help. Let us know!

I did notice it does seem to behave better when set to simple for the screen off animation.
My screen protector does have a cutout around the sensors. Keeping the sensor area clean enough to qualify as having OCD does seem to make it work properly the first time, every time. Maybe it's overly sensitive?
Edit: Scratch that. 30 seconds later it's behaving erratically again. Maybe it's not the fact that it's clean, but the swiping over the sensor that temporarily resolves it.
it also seems to work much better when knocking at the top of the screen where the statusbar would be.
So I ended up swapping the phone out over the weekend for a new one and now everything seems to work just fine. Seems to indicate that it's not a software problem, but rather a hardware issue with the proximity sensor.
Guys if your covering the sensors when turing the device screen on it will turn right back of on you. It's a feature LG implemented so the device wouldnt wake up in your pockets. Don't cover the sensors.
Need a little example? Grab your phone and cover the sensors and knock knock knock.You can knock till the cows come home but it will not turn on. Same thing goes for the power button but its a little delayed and will turn the screen on for half a sec and turn right back off. Practice not to do this because your phone isn't broken. There is actually a thread on this deep in the forums somewhere but its been forgotten now.

This is true however there are indications of problems with the proximity sensor as well. Some of the devices are behaving as if tree sensor is covered even when it's not.

Thanks for this.. Very insightful.. I tried it immediately LOL
I had the same issue. I have no case or screen protector on, and was not covering the sensor when trying to wake the phone. For some reason though, knocking wouldn't wake the phone, and pressing the power button would only turn the screen on for a few seconds. I want even given enough time to get past the unlock screen. I went into the store and they are sending me a replacement that should come in later this week. It doesn't happen all the time. It is much more noticeable after receiving a call though.

Definitely is dependent on the proximity sensor. If i just have my thumb on the edge of the phone by the sensor it will display this problem. Even with my finger a half to one inch above it will do this. I will be paying close attention to the proximity sensor from now on when it doesn't work. Still have a few days to return and thought i had an issue but maybe not.

sometimes its also greasy fingers, at least in my case, rarely though
As long as you tap twice the same place it's working fine. If distance between first and second tap is greater than 1 - 1.5 cm it won't work.
Got the same problem on my d802...when i left the phone on my table for 2-3min it wont wake up on first knock knock even power key wake it up for 1sec after auto turn off again....even with no screen protector....i noticed that sometimes there is a delay about 5-10sec after knock knock and screen turns on....other thing i noticed when i knock on immediently after turning off it works 100%....BUT i also noticed when i knock on after a while it turns on and i can unlock got vibration and sound of the unlock but i cant see anything. Screen looks like its off but when i look closely i can hardly see widgets and when i set effect to tv out i can see the effect by pressing the power button...when i press the power button again screen turns on like normal...i noticed sometimes on a rerboot the lg bootlogo disapears the led is working an showing all colors but the boot animation is gone like the screen is off at the bootup...dont know why after the bootup the pin lock screen is showing up normal....sorry for my english^^
I went to the Moto app and turned off the ambient display and I've noticed that for the past 12 hours my screen hasn't been lighting up anytime I jiggle the phone
That's basically what it's supposed to do. The screen will turn on and display the clock and notifications whenever you pick it up. It'll turn off once you put it back down.
i realize that but it was causing my screen to turn on when i wouldnt be touching it or when it was in the dashboard holster.

That's because it relies on the gyro to detect when you're lifting up the phone. Sometimes, when you unintentionally move the phone, the gyro triggers the ambient display.
Its not a perfect system, and a lot of work needs to go into it, but for most users its fine. Best part? You can turn it off if you don't like it.
Cheers.
