So I'm using the CM11 4.4 Kitkat on my Galaxy S4 and recently found out that my proximity sensor isn't working (when I dial the screen goes black and won't turn on until the call is over). I've read many threads about fixing it but I think it's broken. So all I want now is to disable it but there isn't such option in the Cyanogenmod. Is there anyway to disable it, like with a terminal or something?

with root explorer go to system/lib/hw and go all the way to the bottom to the last sensors file. its an so file. long press on it and open in text editor. somewhere in the page almost at the bottom you will see where it says ProximitySensor then on one of those line it should say mEnabled. just rename it to mDisabled, then reboot and the proximity sensor is fixed.

I know this is an old thread but qman66 you are AWESOME! Was going nuts trying to fix the proximity sensor problem. Ran the commands in terminal emulator that recalibrates the sensor, didn't work for me. Blasted the speaker with compressed air, also didn't work for me. But this method allowed me to disable the proximity sensor while still using an AOSP rom. I will send the phone in for warranty eventually, but I thought I was going to have to use a touchwiz rom until then (touchwiz has the option of disabling the proximity sensor in the call menu).
And I read like 5 or 6 different threads dealing with the Galaxy S4 proximity sensor issue and no one else posted this method before.

glad someone found this useful.
While this fixed the call locking problem, it also disables a lot of other hardware sensors. The only one I'd care about is the gyroscope for rotating the camera and watching videos full screen. Any solutions?

Yeah I noticed that, the best solution is to get the proximity sensor fixed in the end. Then you don't have to disable anything. If your lucky it doesn't even need to be replaced, just cleaned. For me I can live with no rotation, because the screen off during calls is a ridiculous PITA by comparison. Also apps can force landscape mode even with the gyroscope not working. I use force landscape for videos through mx player, and mango reader for manga.
I finally broke down and took the phone apart. There were no warranty stickers to break so assuming you don't mess up royally, it shouldn't effect your resale value. All it took was an eye glass screw driver and a q-tip. Once I was inside I tried the can of air first, but didn't help. Swabbed the back of the glass with the q-tip and that finally provided lasting relief.
i9100 proximity sensor doesn't work
Hi to all!
I have the issue with proximity sensor and didn't manage to find a solution in other similar threads!
The matter is that it is always stay as Released.
In the same time in test screen (*#0*#) there are changing reading for PROXIMITY parameter from 2 up to 240 with no ADC parameter at all. Please look for screenshots. PROXIMITY parameter changes its value when I move my finger in front of the sensor, but as I can understand Android doesn't recognize it because of ADC absence.
Moreover I tried to change proximity sensor for working one (from another phone), but it shows the same as mine (with no ADC readings).
After all I think it is software problem, but I don't know how to solve it. I flashed different firmwares (now it is XWMSE NeatROM v.6.4), but nothing helped.
Please assist! Thanks!

Changing the rom isn't going to do anything, even factory roms (I've tried it). If a replacement sensor doesn't fix it for you, then it's going to be hard to fix it yourself. All the posts I've seen so far have cleaned the sensor or replaced the sensor and fixed the problem. Otherwise people like me just turn the sensor off.
You were right, proximity software fix didn't help! But how is it possible to work in this (the same wrong) way with changed sensor? Can it be some main board hardware problem? But it doesn't look like this...

Samsung S4 Active w LOS 15.1 (a&Droid 8.1) - how to disable HW sensor(s).
Hi All
Hope some here will help me stay afloat long enough to learn to surf by myself; bit of a noob in this wild ocean here (more of a 'fresh water/indoor pool' kinda dude I guess) - but trying to break out of tis little pond and learn to 'surf'. Anyway, to the point:
1. HW spec
Samsung Galaxy S4 Active
GT - i9295
TWRP 3.3.0-0
Lineage 15.1 20180227 jactivelte
(sometimes with opengapps pico and addonsu15.1 but mostly just LOS and addonsu nothing else)
2. Have the sensors on phone covered up with black electrical tape - all but the notification light are covered and it's gonna stay that way - NOT negotiable!
Obvious Issue: Have the blank screen during phone call problem. Can end calls using power button but I need to use the keypad quite often so need the screen to stay on. How? Ideally want to (SW) disable most if not all hardware sensors - how?
Tried a few fixes but no luck, e.g.:
(a) adding 'the' fix/control many sensors apk no good as not suported under 8.1 (plus want to find out how to do manually myself not use 'hand outs').
(b) edit selected sensor etc ".so" (eg in system hw) files - so far not resulting in the disabled ProximitySensor.
So, I really want to hack this myself at cmd line level, am ok with that (many years IT ops/admin experience in 'fresh water commercial space'). Can mount system using TWRP then adb shell to connect and find and grep for stuff in files but cannot find setttings I need to change to disable sensors for good. Where to look/find more info?
What do I want to achive:
Make calls and have keypad stay on all the time or give me manual option to turn screen on/off with a hw button during call.
How:
I am happy to disable pretty much all sensors (proximity, gyro, compass etc) in system or firmware memory so that I am free from the overlords and really want to be able to use the keypad during calls - and have option to manually turn screen off/on during call would be cool.
Constraint:
Really want to do this from (a) cmd line or (b) edit code/recompile (learning curve) the LOS 15.1 or whatever to disable sensors for good. I will be using this old thing mostly for just call and txt not much else - and cannot be asked to buy an old Nokia handset.
Thanks,

why every build claims to have light sensor works while it doesn't. I tried every build that says light sensor works. Well, that works only If I open an app call "Android Sensor Data", then I can see the light lux changes as well as the screen brightness, once close the app, the system just wont update the light sensor......
can anyone confirmed that it's actually working? like put the phone under a lamp and the screen will have full brightness?
No, it doesn't work properly... WiFi, data, G-sensor, battery, camera aren't good also. Bad luck...

it does work, but not properly. U need to enable "Automatically Blacklight Adjustment" under WinMo before boot into Android. Light Sensor works on fresh reboot, but after using android for awhile, and light sensor not working anymore. To get Light Sensor works again, u need to fresh reboot android again
thanks, will try. I am using chucky droidrom and can't find auto brightness option.

Thank u so much. I finally managed to find the registry key that controls auto brightness in chuckydroidrom, and now auto brightness in android works (for now)
BTW, I am thankful to the developers, however, thought they should clear things out instead of just saying "it works" and omit the part "how".

I open phm registry editor in winmo(included in "tools"), search "backlight" in the current user section, u will find "backlight" under "control panel", there are several keys in it. change "lightDetectOn" to 1 and the screen brightness will change immediately according to ambient light.

PS. after some time, auto backlight stops working..... and I think the sensors still works coz when I open android sensor data, it reads normally, the system just ignore it after a while.
Thanks for the enlightment. How about in the Android,do you change any settings?
didn't change anything, just enable auto brightness.
I am having a problem with my sensor not re-activating the screen when I move away during a call, and when I push any button except to end the call, the phone just disregards it. Is there an app or something similar to reactivate the screen with a button push, or is there something I'm missing?
can anyone help?

Hi !
I'm facing the same problem since I upgraded to ROM 3.14.406.2 (french ROM)
Everything was fine before this upgrade.
What I've found is that while calling, when you put your phone away from your face and that the screen is off, if you put a light near the sensor, the screen turns on again.
I think HTC messed up while configuring the proximity sensor values in this ROM...
kinda annoying indeed !

Just install CHT 2.0 (and CHTE and CHTS ). There you´ll find a lot of toggle switches. One of them is for activating/deactivating the proximity sensor and another one is for relighting the sensor. That helped my HD2
Is there a workaround or fix to the proximity sensor issue when using CyanogenMod 10.1? It doesn't matter which dialer I use, my screen goes blank and I can't get it back on to use the keypad or hang up.

If you are using a screen protector, there is a known issue regarding placement. If the protector cutout is too close to the sensor, it will interfere with the proper operation of the sensor and blank out the screen too easily.
I ran into a similar issue, turns out the tinting on the screen for the sensors had gotten dirty inside and I had to disassemble my phone and clean the sensor Windows. However if you don't like the idea of disassembling your phone, the HTC rezound proximity calibrator app on Google play might be helpful to you. I would try the app first before doing something more extreme.

I don't have a screen protector. This solved it for me. Many thanks.
That said, the settings I'm using are a little weird. I have the Low set to 81, and it doesn't seem to matter what the High is set to (currently 100).
This fix works

this totally worked to fixed this same issue I have had. I used to have to go outside on a sunny day for my screen to come on while making a phone call. Once I used this app I was able to get it to come on in a dark room with hardly any light. I may at some point open her up and actually clean the inside of the sensor cover, but for now this worked like a charm.
Thanks for the tip.
One item to note, if you do decide to open your phone and clean the sensor windows, don't clean too aggressively or you will remove the tint from the backside of the glass. Just a tip.
I'm glad you guys have gotten your sensors working again.
I just had this problem today. Previously I never had issues with prox sensor, but just a couple days ago I did a complete wipe (data, cache, dalvik, system and internal SD card) and installed RC1 with a fresh install. The app mentioned above DID fix my issue however I know its a ghetto fix. Before running the app, the proximity sensor would work normally in good light, but not in low light. After running the app it works even in dark light which is great. However, I know its a weird fix. I can actually see the red proximity sensor during calls, when I couldn't previously. I'm glad I got it working, but I know there is something wrong still, and it's definitely ROM related as opposed to hardware because just 2 days earlier it worked fine before the clean install. Hmm..

I’m having a serious issue with my Samsung Galaxy S2 GT-i9100.
I was on stock 4.1.2 (rooted via Siyah kernel v6 b5) probably when the problem occurred. The problem is that whenever I make call, the proximity sensor light up and it make the screen black out even if I’m not holding the phone to my ear or so. It’s just lying on the bed. The screen doesn’t light up and I can’t hang up the call. I just can’t do anything till the other person hang up. Pressing home button and Power button just don’t work to make the screen go on.
P.S: The proximity sensor turns on when I first made a call after a reboot and it didn’t gooff till I restart even it stays on after the call.
I have tried formatting internal sd card and also wipe data/factory reset, clear dalvik cache, clear cache partition, flashed stock rom 4.1.2, flashed nexus 2.0 and even downgraded to official 2.3.5 but it didn’t worked out. I even tried to restore the EFS folder from my old backup but still it didn’t helped.
Here in the screenshot you can see the proximity sensor is active, on the home screen even no call is being made.
Please does anyone know what the issue is because it was working before?
Anyone?

Through testing I have determined that the "phone-going-automatically-to-speakerphone", any time I pull my head more than five inches fro the screen during a call, is due to the proximity sensor. It was not like this before the latest update.
I defeated this by placing a tiny piece of black electrical tape over the proximity sensor.
I would rather just turn the proximity sensor off, or at least turn the "automatically going to speaker phone) function off, but in past requests no one seemed to know how to do that.
So, I am left with just turning off the proximity sensor off.
Anyone know how?
Thanks.

My US998 20G (January 2019 security update) does not have that proximity sensor/automatic speakerphone feature.
I would love that feature, because if I need to check something on my phone during a call, I can keep listening/talking to the person on the call. It's actually a feature you can enable on many custom ROMs, like Resurrection Remix.
I'm curious why you do not like it?

You can try this:

There's also various apps that claim to turn off/disable proximity sensor.
You may be able to enter the H932 hidden menu and turn off the proximity sensor.

See post #1 of the link I included.
The hidden menu has calibration, and other technical features not available to normal people, thus it's called the "hidden menu". Be very careful messing with anything in there, however. One time I screwed up something in there and had to do a Master Reset (got stuck on one LTE band).

That came up when doing Google search for disabling proximity sensor. Some handicapped people need to bring the phone very close to their face without the screen going dark, so that was the suggestion for them on how to turn off proximity sensor. I thought it might work for you also.
What you want to do is very unusual -- turn off proximity sensor to disable a feature only you seem to be complaining about. I'm just trying to give information.
Thank you Chazzmatt! I wasn't trying to seem like I didn't appreciate the help.
For me it doesn't work because I work with my phone and it going automatically into speakerphone ode reveals Private client information to others who may be standing nearby.
But thanks. I figured out how to make it work. I simply places a tiny (one eighth of an inch) piece of black electrical tape over the sensor, and now it's fine.
Thanks again.
