Re-calibrate Proximity Sensor - Xperia Z2 Q&A, Help & Troubleshooting

Hi! The proximity sensor no longer works, so no Ambient Light Sensor, etc. I tried doing the test in the service menu (Proximity sensor no longer an option) but tapping "Ambient Light Sensor" displays a toast notification "This device does not support the function." I'm currently on eXistenZ 4.0.0 and AndroPlusKernel v14. Bootloader is unlocked. Problem started after I REFLASHED eXistenZ. Everything was working before, but I wanted to change an option and reflashed the Aroma installer for eXistenZ.
Repairing via Sony PC Companion does not work, nor thus flashing any firmware and wiping all data. I've read on different forums that sometimes flashing roms does this, and can be fixed by recalibrating the sensor.

Note that the above is for Samsung. I tried browsing to that location via Total Commander but there is no "/proximity_sensor". Do you guys have that? If so, mind uploading it so I'll try pushing it to my phone? There's also a calibration menu for Xperia Z I think that when bringing up said menu from *#*#SERVICE#*#*, you'd simply tap proximity sensor and it'd be fixed.
Any suggestions (aside from taking it back for warranty, since I bought this from the gray market) would be helpful!

[Q]Working Light Sensor

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...

why every chef says it's working then? Really confused, I tried at least 4 builds tonight, frustrating.....
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.
Lets just be thankful that we got android running on our phone...if you must have auto light, use winmo...

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 googled all night, read carefully every 1st post in every build, couldnot find anything related, that's why I asked
Thanks again to every contributor

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.
launch android
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.

proximity sensor is not working v20c P500

on the sensor firmware blunt, the screen turns off it is not possible to disable the incoming call, is sent in direct sunlight, or bright light from the lamp sensor works.
on V20c 2.3.3 proximity sensor is not working officially release
on version 2.2.1 v10g sensor works correctly)
on version 2.3.4 CM7, Void forever works

how fix it? disable?
up 22.07.2011
in v20e Proximity sensor is working but randomly, random screen fades out, then turn on, turn off during a call.
And why did you have to post in this section?
I have similar problem - with v20c proximity sensor during the call is switching screen on and off randomly (even when phone is on the desk). But in hidden menu test everything is ok. I don't have this problem in any froyo roms, or cm7.
Unfortunately, LG f*ck*d update to Gingerbread, many users have problems and are waiting for a good custom roms.
To end calls turn on ending with power button - settings > accessibility > power button ends call

I have exactly the same. Perhaps phone application is poorly calibrated with sensor. Like everything in this official update.
I'm not having this issue on v20g. However, I have the following added to my build.prop (thanks to Noejn)

[Q]Proximity Sensor doesn't work anymore

So here is the story.
I flashed CM Mini 10 with the proper Kernel etc. Since then my proximity sensor stoped workin. This means no landscape on any app nor any activity on compas apps or apps that use the proximity sensor. (ALTHOUGH Proximity Lock App seemed to be working. The screen turned off while covering the sensor)
After that i decided (it was a decision which had to do with the whole daily use and stability of the rom) to go back to Mini CM 7. So i flashed the proper Kernel and the rom. Everething works fine except the proximity sensor.
Any help would be appreciated.

It's not the proximity sensor, that only detects if something (you) is close to the phone, so it can turn off the screen and prevent accidentail touches when you're in the call. It's the motion sensor that is not working properly

Proximity Sensor Issue!

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?
I think you should replace the sensor....it's just 3-4 dollars,and it comes with the front camera and light sensor(AIO)

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!

[Q] Galaxy S4 Proximity Sensor disable

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?

bump!
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.

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,
iHAL8999.999... (hi dave...)
