Hi,
I am using red lense defy and CM10. When I use the dialer to call others, the screen will be automatically turned off and I have no way to lit it again during the call. Thus I cannot enter the choices for languages when calling these automatic voice machines. After the call, it will be lit again.
I used to have CM7 on this defy. The dialer worked pretty well. However, Skype on CM7 had the same problem. Now I can use the keyword while using Skype, but the dialer fails...
Who knows a possible cause for this?
Ok I've found the problem by myself. The proximity sensor is not working well. After cleaning the screen it works now.
However, is there a way to disable to proximity sensor in case it is malfunctioning?
Please ask all questions in the Q&A section. Thread moved there.
proximity sensor prob
my defy's screen is turned off during calling/answ. ok, its normal.
but i have no way to get the screen on again!! even not after the call has ended. the red light rom sensor keeps on glowing. i have to re-install battery.
i updated to cm7.2 yesterday. evrything is just awesome!!
before that i was on 2.2.2 official.
also my device's proximity sensor is not working well. between the range of 0 to 100cm, it shows 0 everytime.
same problem during call was there in 2.2.2, but i was always able to glow my screen.
pls help me with this. any way disable the functioning of proximity sensor?
Screen protector?
I know this thread is old but in case somebody stumbles across it like I did. I fought with this problem for about 2 weeks and finally pinned down my cause. I buy large protector sheets for tablets and cut my own to fit my defy. Works not bad. First time I ever forgot to peel the cover layer and got this problem. Before getting too crazy with programming, try removing your screen protector or at least the dummy layer that you remove after install. http://forum.xda-developers.com/images/smilies/eek.gif
I found this topic about the design flaw:
http://forum.xda-developers.com/showthread.php?t=2129140&highlight=proximity
I've seen it myself, when I was reassembling my phone. Hardware design for that particular part is absolutely HORRIBLE.
It happened after changing the motherboard on my phone. In-call screen turns off immediately and doesn't turn on until the call ends.
Proximity sensor seems to work OK when it is out of its place on the phone, but after placing it back, the path is blocked somehow.
I got a spare part to interchange, but it behaves the exact same way the previous did.
There is a rubber gasket, it fits nicely and holds sensors in place, but it might block the sensor. Without the rubber gasket, sensors are not fixed in place and they work inconsistently.
I am curious, if it is a special way it is assembled, or I am a dumb ass can't figure out how to place it properly.
Please help, otherwise it would be great to know, if there is a way to turn it off in software. Thanks.

Tasker can turn off your proximity sensor while on call.. I think some custom roms also have that feature..
Would be great.
u can use proximity disabler
i lost the rubber thing when i changed the screen!!
i followed these two methods
i used proximity disabler from xposed framework to stop the proximity sensor
you can get that from
http://repo.xposed.info/module/com.mrchandler.disableprox
or follow this tutorial
or
i fixed that using a small cardboard an made two holes exactly infront of the sensor
and that fixed my proximity sensor for my nexus 4 and even made a video for the same you can check that at
Hello all, I know this issue has been raised before but there hasn't been a fix. I'm currently facing trouble putting my G2 in a waterproof ziploc bag because of the proximity sensor. It detects that something is in front of the phone and doesn't allow me to turn it on. I can't knock-knock to turn it on. The moment I turn it on using the back button the screen will time-out. This is a feature of the phone, not a defect. I want to know how to disable it. Please, if anyone knows how to do it, tell me! Your help will be much appreciated!
Edit: if you want to replicate the problem try putting your finger on top of the front camera - the phone will not turn on when knock-knock
Android App Disabler
I have found an app that may help, but I do not know how to use it! If anyone knows how please tell me!

Wierd, I just experienced what you are talking about by testing it out. If the phone is already on and being used and you cover the proximity sensor it doesn't turn off, but, if it is covered as you turn the phone on it will immediately turn itself back off. Even if you use the button and try to swipe the screen quickly it doesn't prevent the phone from turning off automatically.
Unfortunately, I am not able to help you with this problem as it is fay beyond my limited knowledge of linux/android etc. However, maybe this reply will cause someone who can help you with an easy solution.
One thing that would almost certainly fix it would be to switch to one of the alternatives rom not based on the stock LG software/kernel like Cynogen Mod or Android Open Source Project, etc. Those roms use a different kernel and also a standardized version of android that is open source. So the sensor problem will likely not be an issue, however, I believe you lose either knock on or knock off functionality with Cynogen Mod, not sure which one as I am still running LG based rom.
Some people prefer the open source alternatives to the LG rom, so, you might even like it better than the LG setup. However, it will require some effort/reading to learn how to root your phone. Then to flash your particular model of G2 with a custom recovery and then to install a rom/kernel. It is not that hard though, you just have to acquire the knowledge to avoid bricking your phone by doing something foolish.

Thanks a lot for the tips but i think there should be a way to disable the proximity sensor on the stock rom. If all else fail then i will try and install custom rom like the ones you mentioned.

Yes, it would have been a nice feature for them to include, I wonder if they just overlooked it. That being said, I'm not sure if there is anyway to do it on the stock rom. Hopefully for you it will be possible in time. Good luck!
I can confirm that CM11 is not affected. I put it in a baggy and it will still respond to all input.

Really? That is good news! Sorry but im to custom roms - is aosp or paranoid android rom based on cm11? I believe those are one of the best custom roms for android. I might install one of them soon.

I think you meant AOKP? But either way, AOKP, PA, and CM are all AOSP based ROMs. Just different paths. PA has some really great features right now, but lacks a couple tiny things that keep me on CM11.
If you're looking for a no frills mostly stable ROM CM11 is probably the best choice, plus Delta updates make it pain free.

I get some here and there, nothing major. Delta updates take the nightly, and process it to pull only the changes, so you get about an 11mb update instead of a 150+ mb update. Its all in an app.

Working
i have a g2 d802 and i have tried the script workaround and is fine, but when i do put the phone next to my ear the screen remains on and does not go off, is this something i can chhange?
is there another workaround?
i am using Cm11
Had the same problem.
Great temporary fix: right after you unlock the screen hit the volume button once or twice. Not a permanent fix but it works for the time being.
It usually blacks back out because something is wrong with the proximity sensor next to the front camera. Either it's covered partially, dirty, a screen protector is peeling off over it, etc. I've read that some people have problems with the screen not coming back on during calls because the proximity sensor is messed up. Some said to use a high powered suction vacuum and put it up against the screen to get debris out of the cracks or simply try wiping it clean if there's something on it. Hopefully it works!

Oh god, I just permanently fixed my proximity sensor \o/
So I had the issue where the proximity sensor would detect something near it, making it hard to wake up the phone (screen getting dark after half a second, as the phone thinks it's still in my pocket) or keeping the screen dark after a call.
An app displaying the proximity sensor output was showing the sensor always reporting 0cm when it's not working, and 5cm when it's fine.
If your get "no data" in a test app, then sorry you have another issue. Probably a dead sensor. If you do get the sensor always returning an obstacle at 0cm, keep reading!
I also noticed that pressing on the screen around the sensor kind of made it work. So I thought for a while my screen was slightly off, maybe slightly unglued.
But it's the opposite: it's actually the sensor that was moving a bit, thus getting too far from the screen surface - and detecting the screen as the obstacle. Just by a ridiculously small amount.
Now THE FIX:
I switched off the phone, and removed the SIM and the rear door,
I removed the 7 screws holding the top plastic plate and buttons
On the rear of that plastic plate with the buttons, there's a small soft pad that pushes on the sensor to hold it against the screen: that's your target! That pad is just a tad too thin.
I've put a very small piece of adhesive tape (I used a slightly thick double-face white tape, maybe a tenth of a millimeter) on that pad,
Then I put everything back together and... the sensor now works! All the time! And the knock-on too of course.
I can't post a picture of the pad below the button assembly. But if you look for "OEM Part - AT&T LG D800 G2 (WHITE) Rear Back Housing + Buttons + Camera Lens" on ebay, and look at the 2nd picture, the pad is the fully black rectangle on the top left, on the right of the empty black rectangle and below the half-circle small opening (probably for the light sensor).

proximity sensor issue
i had the same issue for my lg g2 . when i searched the internet for solution , all i got was to install proximity sensor disablers , rooting apps to disable them . i have solved the issue interms of hardware . the solution goes :
1 . go watch a youtube video of teardown of lg g2
2. in the video there will be showing a plug that connects the sensor to the circuit board.
3 . pick up a screw driver , open the casing of ur phone
4. unplug the connection between the board and the sensor
5. put everything right back
6 PROBLEMO SOLVED BAYBE
thank me
Just in case someone searched and finds this thread - the easiest way to disable the proximity sensor on any rom/kernel is to go through Xposed and this module: http://repo.xposed.info/module/com.mrchandler.disableprox
Works on 4.4, 5.0.2, Cloudy's rom, Dorimanx's kernel...
Big Thanks!!!

After almost a week trying to solve this, your answer hit right on the spot! I found it funny how the roms not based on stock LG's are not affected by this issue, but all of the LG's ones (I've tried 4 LG's stock roms and CloudyG2) so I've always assume this was a SW issue (and probably can be addressed via SW) so when I get to your answer saying that could be fix tearing the phone apart I was reluctant to do so, but as I've told you guys I was desperate. On a sidenote, the Stock JB ROM is not affected by this, but it is death slow for this times.
BTW, I've wanted to have a ROM that had the LG's camera app (any version) since the ones that came on the CM ROMs wasn't really good enough for my taste, so now I'm rocking the CloudyG2 3.2 ROM with any issues so far.
Your fix gave my phone some solid 6 more moths of life! (at least!) THANK YOU!
So i recently upgraded to Lollipop but my proximity sensor is broken. I used an app called Proximity Screen off lite but it is not working on latest android lollipop. So now when i make a call my screen goes dark until the call is disconnected from other party. same is the case with incoming call. Please help
I was in the same situation as you last weekend. Unfortunately, there's no way to get around it in software that I know of. I even went as far as developing an app from scratch to duplicate Proximity Screen Off Lite's functionality, but ended up hitting a road block on the OS level. Another option that would've worked pre-5.0 was to use an xposed mod to disable the proximity sensor, but of course that doesn't work in 5.0 now. Hopefully someone else can chime in with a software solution that I couldn't figure out.
Did you replace your phone's screen by any chance?

I replaced the original screen with an after-market one as well, and that's what caused my proximity sensor issue. There is a good chance your proximity sensor is actually working perfectly, but the after-market screen is blocking it from reading a "far" value. If you're comfortable with taking your phone apart, you could fix it without replacing anything. There were two things that I did to fix mine, but I'm not sure which of the two actually did the trick. 1) I repositioned the sensor so that it sits further away from the glass, and 2) I scratched off the black paint on the back side of the glass around the two clear sensor holes. Obviously you should attempt option 1 first, because the second option is permanent and will damage the aesthetics of your phone. Others have reported success with option 1, by gluing a thin spacer with two holes to the front of the sensor, but I did not have any luck with it when I tried initially. You will find that it helps a lot to do this while the phone is on, and you can see the results of your changes immediately with the Proximity Sensor Finder app.
Edit: Before you attempt any of the fixes, you should verify that your sensor is in fact working by pointing it away from the phone after opening up the back.
I had the same problem, I gave up on a software fix and I ended up taking the phone apart and fixing it outright. It's not too difficult, all you need is a plastic tool to open the case and a T5 and a 00 screwdriver.
There's a good youtube video (I can't link - see /watch?v=AZDAIgwbXk4) showing how to do it. Skip the battery section, you can keep that in place. At 9:00 he indicates where the proximity sensor and light sensor are. Take the small rubber gasket that covers the two sensors, and flip it around so that the larger hole is over the proximity sensor. Put it back together and turn it on, it should work perfectly.
Also, in the interim, you may wish to have your phone end calls with the power button, it can be found under accessibility settings. At least that way you won't be stuck waiting for the other party to pick up or hang up.

I had the same problem, solved by a thin plastic sheat that I drilled two holes in and then cut to the right size.
I placed the plastic part in the bottom of the hole, where to fit the sensor. I also shaved of aboute 1 mm on the part that presses the sensor from the back.
( I hade already taken the blackish film away in a own attempt to fix the problem, at least the light sensor seems to meassure more accurat)
Hi all, I've similar problem on my LG G2 D802. I have tempered glass with covered prox. On KK everything was OK, but unfortunately Lollipop has much more intensivity on prox
and I had the same issue as you, I mean - turned screen while I maked call and vice versa. Moreover, I can't get in to the service menu on LP (AOSP 5.1.1).
I bought new tempered glass with uncovered prox but fortunately Xposed has working old module: Disable proximity sensor.
I don't know about what module you guys talked about but this module works very well.
I tried installing the xposed framework but that threw a little notice saying it wasnt going to work. I looked for apps ont he app store but that didnt work as well..
Any ideas on how to disable the proximity sensor so when I turn the screen on it doesnt turn right back off?
Any help is greatly appreciated.
the issue might be your proximity sensor's alignment. it might not have aligned properly. there is a small black rubber holder to hold the proximity sensor. may be you might be missing it or might have loosen it. you can easily fix/align it, if you can open the back cover.
you can install a custom rom to overcome this sudden screen off issue. but when you taking a call your screen will be turning off until other user disconnect the call..
I suggest you fix/align the proximity sensor..
P.S:
There is a small troubleshooting step you can do to see whether your proximity sensor has a slight alignment issue. get a torch or good direct light source and point it directly at proximity sensor. if you can turn your screen on while pointing that light towards proximity sensor, you should have a very small alignment issue. there are plenty of proximity sensor test apps on play store too.

that makes sense.. you also replced front housing too right? that's where that rubber proximity sensor holder attached.. if you replace original front housing with aftermarket housing that rubber holder probably won't come with it. most of the repair technicians don't know this.. if you still have the old front housing you should be able to recover it and attach to your new housing..
p. s:
or you should be able to buy it.

Honestly, if its possible I'd rather just disable it completely. I'd rather not open the phone up again if I don't have to and I will never use it for calls anyway.

if you're not using your g2 for calls, I'd recommend flashing a custom aosp rom. so you wouldn't get in to this sudden screen off issue while unlocking it..
