Lg g2 proximity sensor - G2 Q&A, Help & Troubleshooting

So my phone turns off right when i turn it on.. I've been lurking around and I've heard its the proximity sensor.. there's an app called phone tester that i got from the play store, it said the P.S. was "far"
Do all the G2s say that or is it just mine cuz it's faulty?

So I'm assuming this thing is a front facing camera?

Does anyone else see the camera thing in the upper left of the G2? Looks like a camera to me.... It's not easy to see but it's there. Sorry if this has been brought up before...
What do you know about the front camera?

That's probably the proximity sensor.

The G2 does not have one. That is the poximity sensor and light sensor I believe.

Uhmmmm.....I don't have a G2 but im pretty shure what your seeing is the proximity sensor for the phones screen to turn off when you put it up to your face.
Nah its light sensor and proximity sensor. Sorry

Filed under wishful thinking
it would have been sweet if it was a camera to do chat and stuff but no, its a sensor
This is exactly what I said when I first received the phone, I was just hoping I was wrong and when we started rooting this device and looked at the internals, we found a FFC.
If it was just empty space, I'm sure one of the hackers here would have installed one just like the Samsung Vibrant.
I'm always amazed at how tolerant this community is of sheer stupidity.

Weird light being emitted from proximity sensor? [Video]

http://youtu.be/8qKYJVnUzwI
I noticed a weird light being emitted from proximity sensor when I entered the stock Samsung messaging app. It looks like it could be an infrared light coming from the sensor, but it's faintly visible to the naked eye. I thought I would take a video of it to show what I'm talking about. It's more apparent in the video than what you actually see. You can see it yourself in a dark room.
Has this been addressed? Does anybody know why this is happening?
isnt it looking to see if you move the phone to your ear in the messaging app so it can do the call feature?
I noticed this on mine last night. It's not like that right now though
I have the Motorola Atrix and when I use the proximity sensor, it does the same thing, glows a very very dim red, only visible in a dark room. Guessing that's how that sensor works in a generic way.

You have the eye tracking on? I just assumed it was that.
SwiftKeyed on my Sprint Galaxy SIII...
Mine does the same thing. It's for the direct call feature for texting. If you turn direct call off in your motion settings you won't see it anymore.

Doh... I feel silly for posting this now... Well, at least we have some sort of visual proof of it?
Haha no worries dude. Really easy to over look the little things! I was curious when I first saw it on mine as well.

I don't think mine's ever done this before and I've enabled smart stay before.
i have that as well...noticed it a few days ago..didn't think much of it
It's direct call for texting. Really it's anything that uses the proximity sensor. Smart stay uses the front facing camera.

Does your G2 rattle when you shake it?

Only noticed this today. The rattle noise seem to come from the upper side of the device, maybe the camera or the sim card area.
I've searched a bit on the net, and saw that the nexus 4 and original Optimus G also suffer from this problem...

Yes it does. They all do. I believe it's a sensor inside the camera. It's supposed to move.

ok so then its not cause i have the vs980 honestly no phone should have loose parts id take it back if you can and see if you have the same problem?
Its the optical image stabilization that is shaking i can confirm it all devices that have this shake!
Mine does. It is very soft and faint. Its the OIS. In all variants.
Yup. Normal. Every camera phone I've every owned does this. I have the VS980 Verizon. It's the camera sensor. It's normal.

I have the Sprint version and it does not rattle no matter what plane I shake it in and no matter how hard or soft I shake it. If it is normal to rattle than I guess I have the broken one. However, I am NOT taking it back for one that does rattle.
My gnex rattle really bad. Lg g2 not. Yes it s camera but I think is rather focus particle than ois
alright yea i can confirm it... it makes a very feint sound i couldnt really hear at first due to backround noise haha sorry if i caused confusion

Add the "knock knock sound" to knock on?

Hey guys, do other G2 variants have this? Im on a vzw g2. I think it would be cool to add knock knock sound when turning the screen on.

i have the att lg g2 and also cant find out how to enable the knock sound. i even asked around here a few times and never get a reply on it. i also thought that my device was not working right .i even called lg and the tech couldnt fighure it out either. they even sent me to pick up a brand new phone at the att store because they said mabe the phone is messed up and all three att guys there coulndt figure it out ..but the att manager had the phone and he said that he has herd the sound on his but coulndt show me .. something weird here with this..mabe its just on the over seas version of the lg idk ..cant seem to get a answer on this
Have to dig into the international roms then I guess.
I swear I have seen people in youtube videos, etc tap tap and get that door knock sound.
What there was never any knock sound in att lg g2 I have been using this phone for the past 2 months idk about international versions

Agreed
+1 for this
Maybe you could add an unlock sound that says "who's there?"

no double tap on / screen replacement /proximity

Hopefully someone can help me out. This is verizon vs980. I needed to replace my screen bc I got a dead zone in the digitizer. In my experiences with screen replacement, replacing just the lcd/ digitizer assembly never goes well, aftermarket double Side tape never holds it to the mid frame like factory. So I opted for a digitizer/lcd/mid frame assembly. Simply swap the guts. Everything went well. After about a week the digitizer began lifting from the mid frame (as though it weren't factory assembled) . Little mad about that bc it's the whole reason I opted for that type of assembly. So I decided to return it. This time,I figured if they're gonna lift like that from the "factory" I might as well save the twenty five bucks and just buy an lcd/digitizer this time and stick it to the mid frame myself. I did. Once I was totally done, everything seemed to be just fine. Then I realized the knock on does not Work, and my proximity sensor was acting up. Didn't worry about the proximity sensor since I'm taking it back a part anyway to send this assembly back bc knock on isn't working... So I sent it back. Got a new one, same issue ! No knock on and proximity sensor is acting up. So , suspecting proximity sensor as culprit I unplugged it. Still no knock on. So I then pulled the proximity from the housing and Used a proximity tester app to test it. When its out of the mid frame, dangling, it works fine (still no knock on) but when I put it back into the midframe housing the proximity sensor registers something in front of it ( no its not glue or tape, digitizer is unattached permanently at this point) confused I looked at pictures I took from that very first assembly that I took before returning. I found there is a black housing trim that I accidentally left in the housing I sent back ! It pops into the midframe, then the sensor pops into that.. I suspect this is why my proximity sensor goes haywire when it's in the assembly, but why is my knock on not working?! That black piece I left in housing ? Bad sensor all together? Coincidentally got two bad digitizers??? Rom? (Tried to different same result) stumped. So to sum it up right now, I have no knock on, and the proximity sensor constantly registers something when it's placed into the housing, but works fine outside the housing.
Did you update touch firmware?
Dial 3845#*8xx# / settings/ update touch firmware
8xx or 9xx according to your model , example 8xx/9xx becomes 802 on g2 d802

No I didn't, I don't have my sim card in to access the dialer. Suppose I could try that, but it worked just fine with the lcd/digitizer/frame assembly. Is this something you're supposed to do after a screen replace?

Your welcome. Your probably the last one I helped with g2. Counting down the hours till I get my g3 this afternoon. Would've kept this baby, but no microsd was always a killer for me.
