[Q] How to disable Proximity sensor in Nexus 4

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 did the same thing. It's a common issue, and that's the typical fix.

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.

Issues After Screen Replacement on G2

So a customer has informed me that they are having issues with their G2 after a screen replacement.
The issues are:
-Screen is blurry (obviously will need a new screen)
-Knock on isn't working.
-When she unlocks the phone it sometimes locks itself again.
-Screen does not wake back up when proximity sensor shuts it off during a call.
I am guessing that all of the issues are to do with the new screen.
Any help would be great.

Did you update the touch firmware for knock on? Maybe the proximity sensor not waking up has to do with the modem. Idk I'm a noob to these things but that's my opinion on what's wrong.

Was/is it a genuine LG screen?

No. It is not a genuine screen. It is an aftermarket screen. I've repaired hundreds and hundreds of phones with third party parts. Never had any issues like this.

the g2 is locked down tighter than apple products. i wouldn't be surprised if the aftermarket screen is a result of all those issues.

Do you have a more detailed reason behind the issues?

Still looking for some info.

it's the proximity sensor. I put a little piece of electricians tape on the pad that pushes the proximity sensor into the phone screen and that solved all my issues. Message me if you have any questions

Hi, I had lots of issues with my proximity sensor too, and I just fixed it. Most of the time the sensor would detect an obstacle at 0cm, preventing knock-on and knock-code, making it very hard to unlock the phone and keeping the screen black during/after calls.
My issue was actually a small pad behind the sensor, that's supposed to push it against the screen: that pad was too thin!
Adding some adhesive tape on that pad solved the issue for good! That pad is on the rear buttons assembly (the one that is hold with 7 screws).
More precision about how to fix:
- remove the rear door.
- remove the 7 screws holding the plastic assembly holding the rear button.
- remove the rear button assembly.
- loot at the rear of that button assembly: on the top left there's a small soft pad that's supposed to push the proximity sensor against the screen.
- add some thick adhesive tape on that pad
- put everything back together: put button assembly in place and clip it, put back 7 screws, clip back rear door.

Agree with the crowd, it's the prox sensor. Same thing happened to me when I replaced a screen recently. The tell tale sign is when making a call, the screen will turn off. This is because it's already sensing that the phone is being held up to the user's face when in fact it's a false positive. I believe there's one of two reasons:
1.) Following screen install, the prox sensor is located an incorrect distance from the small window it looks through. In other words its too close or too far away.
2.) The prox sensor is not correctly centered in the window it looks through and needs slightly tweaked up/down/left/right to be perfectly centered.
I couldn't determine beyond a doubt which one of the above was the case or perhaps both. But after taking it apart a few times and tweaking the position of the sensor, mine started working ok and has now been functional for a few months without issue.

Many thanks on the very detailed instructions. I will try them out tomorrow. What I have noticed though, is that I can see the LED through the proximity sensor window, so it might be a misalignment issue as well. Any suggestions on where to buy a new screen for the G2 ( preferably Aliexpress or ebay).

[Q] Where to buy rubber gasket for proximity sensor?

Hi,
I've recently changed the LCD panel on my Nexus 4, as well as the headphone jack (which includes the proximity sensor) - the screen was broken, and the headphone jack had very noisy output.
After putting it back together, I noticed that the proximity sensor wasn't working - during calls, it would constantly blank out the screen, and there was no way to unblank it (i.e. it seems to permanently think there's something there).
I took it apart again and noticed that the rubber gasket that fits behind the sensor is missing - it must have come off during the repair and gotten lost.
I tried putting some Blu-Tack behind it as a temporary fix, but no change. Now, I'm not so sure the new proximity sensor is working either.
Anyhow, my first question is, where can I buy a replacement rubber gasket? I've done a search online, and I can't seem to find it for sale anywhere?
Is it available as part of another spare part for the Nexus 4?
Cheers,
Victor

I had to replace the screen on my n4 too and fixing the proximity sensor was a pain in the ass. I had the rubber gasket but it was only working when the front panel was not attached as soon as i attached the front panel it stops working i.e. when in call the screen goes off but it doesn't come back on. So what the guy did was to scratch off the two holes on the top left from the inside of the panel. its looks a bit nasty but its working fine now. you might wana try to scratch off a bit neatly. like in a round shape.

I dont know if the gasket is the cause, but I know a case where this exact problem happens : its when u don't push the sensor well enough to fit in its place, cuz it should be near enough, or it'd blank the screen during calls. Try using a flat screw driver, and push the orange part where the sensors are well enough, that should do the work ( don't push haaard or I'll Damage it). I hope that'd help, cuz finding this gasket is hard. And this applies also for the guy who commented, cuz this is the case for him

According to this post:

the LG part number is MBL65457701
I managed to find an eBay seller selling it (original_parts_mobile_99):

I used a small piece of credit card, drilled two holes with t3 screwdriver. Worked like a charm!!!!

I'm rooted but no idea how to disable proximity sensor

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.

Interseting... My screen broke so I had it replaced and its been having an issue ever since. Also, I don't use it for calls. It is just sitting on a mount in my car most of the day running a few car apps. But it is in airplane mode basically all day lol.

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..

Mi 9T Proximity Sensor Issue

Is there anyone else encountering the same issue with me?
I realize my proximity was not working when the screen wont turn off during the call when using the earpiece. I did went into the CIT and performed the proximity sensor test and the proximity sensor seems not even reacting.
Is there any chances that it could be the tempered glass screen protector affecting the sensor to work normally? I found that the phone is eventually something they called it "Virtual Proximity Sensor" so i kinda clueless on fixing this.

Mine is working through the glass.

Apply all the updates, happened the same to me until i applied system updates.

The reason of it is you glass protection.

Works for me. Unless I am in another app whole in call

I face the same problem

The proximity sensor seems to be located on the top right (next to earpiece) literally invisible to at least my eyes. Make sure you have no bubbles in that area from screen protector install and if there's a smudge from your fingerprint it might block the sensor thinking it is placed near your ear. So clean it if it doesn't work properly. Maybe screen protectors with black borders like the Nillkin one require 100% accuracy when applying them?
I do have a line all the way around my phone where my screen protector has and will not stick to the phone.
Can't comment on plastic screen protectors.

I have the same issue on my MI9T Pro. Tested with CIT (4 times click on kernel version appear this tool to check the hardware). First time the sensor worked fine (5.0 to 0.0), second time it was stuck on 0.0
Then I reboot the phone and it has fixed by itself, but this is a recurrent issue, I couldn't solve. Someone knows the real solution?

I have the same problem , i don t know if is a software problem , i think is more a hardware problem . The sensor worked fine ( i think ) until i installed a temperd glass . When i put the glass " perfect " the sensor not worked ...then i moved the glass down , and is working , but not 100 % . In call i must find a position , an in my pocket not seek to work . I use a Wozinsky Super Tough for Xiaomi Mi 9T & Mi 9T Pro, Full Screen, Full Glue.
For me screen protection is very important , and i make thia compromise for now . I Hope to find a better temperd glass !

+1 for the proximity sensor problems... I had 10.3.15, now chaned over 10.3.11 and the same. I have screen protector from Samsung A50. Sensor is going off when I make a call, and didn't came back when I put the phone down.
This is not happening every time, but once in a day/two...

No problem in K20. Using back cover and .2mm plastic screen protector

I think the problem is with temperd glass , mine have black border and i think that is the problem !!

I have the same issue. But I noticed this only happens for the incoming calls and not for the outgoing also I noticed when this happen it's like sensor doesn't wakes up but I have to say that I have screen protector also. I read in a forum from Spain that several users have the same issue even without screen protector.

For the incoming calls, I notice a lot of times that the phone/smart watch is ringing, but the screen is not turning on. Even when I unlock the phone can see that someone is calling...

Screen protector
I have the same issue. I have a tempered glass with black frame too. The proximity sensor doesn't work when the glass is on. It is a really strange issue.

I have the same issue. I have a Xiaomi mi 9t pro and my proximity and light sensor don't work (same component)
But I have a theory. Like many I have installed a tempered glass previously but I removed it some weeks ago because of a crack. But I didn't replace it with a new one.
But who else used the (included) oil to remove the halo effect around the screen protector?
I used it but I think some oil seeped in the speaker grill and this maybe gives errors on the contacts of the proximity and light sensor!? The sensor is nearby the speaker grill.

I have the same problem... Have phone about a month, I've put glass the same day I bought the phone... Does anyone know where is the problem?

All i can tell you all is how to apply these screen protectors, because at the end of the day it is NOT a hardware issue. (sure, maybe a hardware flaw when using it with an accessory such as a protector)
The best method imo is to use tape or the sticky stickers that should come with the pack, so you end up creating a hinge that should always "close" at the same exact spot when you "open and close it".
Only then should you continue to peel of the film after thoroughly but gently wiping off the dust and marks especially near the proximity sensor. Make sure the phone is "naked" and that you do this in the least dusty environment. Do not waste any time after peeling off the sticker but do not rush and risk messing up the allignment. It should be an even gap/space all the way round of the phone. If you feel like you did everything right and it still doesn't work then next time move the screen protectors ever so slightly downwards.
Refer to my first post on the first page to see my phone's screen protector installed. Guess I can take some clearer pictures and show you. Have used the phone with three cases and zero problems apart from smudging the sensor with my ear a few times.
My first post using text formatting lol

I briefly had your issue, i simply cleaned the top speaker grill.

Can confirm, tampered glass with black borders cause this problem. I removed it and now it works flawlessly.
