[Q] Proximity Sensor issue - Sony Xperia ZL

Hi everyone, I owe an Xperia Zl and I have a faulty proximity sensor, the issue is noticeable when I make a call, the screen goes black before I put the phone to my ear and stays black as long as the call is going, the screen stays black even after the call ends, I have to push the power button to turn the screen back on.
I entered the service tests with the code *#*#7378423#*#* and the proximity switch is always on, what I noticed is when I squeeze the screen near the proximity switch it works just fine.
Have anyone of you run into this problem and is there a solution to it? I was wondering also is there a proximity sensor calibration menu like the one in Xperia Z Ultra ? you can see it in youtube search for "Smartphone Proximity Sensor (Xperia Z Ultra)".

Hi,
there is something new with my problem, last night I mistakenly flashed a rom reserved for Xperia Z (eXistenZ v4.3.5 ) and to my surprise the proximity sensor was working fine, I did all the possible tests and it was working perfectly, I had to switch back to a rom for Xperia ZL as I noticed that the battery was draining very fast, screen even turned off stayed lit, and I can't control brightness level,etc...and a bunch of others compatibility issue.
So I guess that there's an issue with the calibration of the proximity sensor, I'm not a developer but the proximity sensor code in the rom of Xperia Z works perfectly for my Xperia ZL, I don't know how to exploit this and solve this problem, if anyone is willing to help I'll be more than happy.
thx guyz.

Anyone please help !!!

energy rom's bug?screen light off when calling

I flash energy's rom,it's good.but screen light off when calling makes me crazy.However I press the power button,the screen does not light on.every way i can do (regedit,change light sensor) does not work.
so please ,anybody knows?
You're saying that no matter what you do, the screen will not light up at all during a phone call once the proximity sensor turns turns the screen off?
yeah,you are right,but some rom can light up during a phone call,others can not.I'm crying for this
I've used Energy ROMS, and they were bullet proof, ran perfect, did everything they were supposed to do, like turn the screen off when I help the phone to my ear or had an object within proximity of the sensor, and the screen relit whenever I pulled the phone from my ear or moved an object away from the sensor...if you're saying the screen stays dark and you cant turn it on even with nothing blocking the sensor, then I recommend posting that issue in the Energy ROM thread as there could be a solution...if you're saying the proximity sensor works normally and you'd prefer to deactivate it, I searched around for that for you and didn't find a resolution...you can, however, if the sensor works properly...cover it up all the time (perhaps a small piece of black tape or something)...you'll have to hit the power button one time each time the phone takes or makes a call but the screen will stay lit til you turn it off again, even during a call
thank you Gt247. thank you so much.I think I found the way to resolve my screen's problem
I read a bunch where people were looking for a way to disable the proximity sensor...perhaps if that's what you've done, you could post the solution here in the event those peple are still looking
I have tried some apps to disabled my proximity sensor,but those all do not work,I think it's my phone's hardware problem,I have already decided to open my phone to fix it.
so before I fix this fool sensor ,any knows which app can test the proximity sensor?
just a app to test whether my proximity sensor work normally, any clue?

You don't need any app to test the proximity sensor , just turn on your screen , and cover the sensor with your finger . If your proximity sensor works normally , screen will be off . When you remove your finger in seconds , the screen will be turned on again .
I think you can disable the proximity sensor simply by removing the shortcut in the "startup" folder , and restart .
If I misunderstood your words , ignore me pls ~
thanks pcgg.I have tested my proximity sensor,it seems not notice my finger,the screen always on.
I have not found the proximity sensor shortcut in my startup folder,here is the file list in my startup folder:
DeviceLockXT.lnk
LockDevice.lnk
SpbMobileShell.lnk
so could you tell me which lnk is the proximity sensor?I can't find the file about what you say by the name
It seems that there is not priximity sensor app in your phone ....
While there is an app called "Rhodium setting tool" in mine , and it has a option under the menu "phone" named "Light Sensor" . If I turn it on , screen will auto turn off during a call .
Maybe you can try that ?
Well , I must say that I did misunderstood your words ... I thought you were complaining an app called "Proximity Sensor" . I found it in the "Jackos" ROM ... Sorry for misleading you .
You can try that app "Rhodium setting tool" . If it can not work , I will have no idea about it .
thanks pcgg.
I have already try the light sensor,I have tried many apps those can control the light sensor,but those don't work at all,at last I get a conclusion that is proximity sensor has a higher priority than the light sensor,proximity sensor can decide whether the screen can turn itself on or off.
my rom now is seeM_ZA's simplicity rom 21916,I'm now ready to flash jackos'r rom.whether it works ,I will tell you the result later
Any of the two, i suspect the first:
- you probably have some dirt inside your phone, at top left corner where the digitizer has a semi transparent glass for the proximity sensor (you hardly see it without disassembling screen)
- the proximity sensor is KO, you have to replace flex to cure it (about 35$ on eBay)
Once i replaced the digitizer on a TP2 and a little drop of glue went near the window of proximity sensor, it didn't work at all till i disassembled all again, cleared the the glue around the window letting again enough light to enter the sensor.

proximity sensor don't work help :(

Hey, after on moth from buying my HTC ONE X now the proximity sensor is not working and the screen turn to black when making a phone call and a small red light are working above the screen, but it works very good under the sun .... any help please??!!
* I removed the screen protector but still not working
THANKS
Peoples here are just viewing no answers?!!
Proximity sensor is used to turn off the screen during a phone call if your screen goes off during a call when you put the phone on your ear that means that the proximity sensor works
Sent from my HTC One X using xda premium
do you mean you cant answer calls because of the proximity sensor turning the phone screen off?
You posted this question around august last year. No solution then, probably not gonna work now after 7 months........why didn't you take action then if i may ask ? You where on the viper x rom it didn't work then also ? Now back on stock ( i helped you find the boot img ? Still no good sensor ?
:S
I have this problem also... sensor don't work... some solution?

Proximity sensor is not working

Hello all
I have replaced a broken touchscreen with the new one (bought on ebay). Everything seemed to be working fine but when I make a call or someone is calling me I see a black screen as display is turned off (just like it does when you put your smartphone to your ear).
I tested all sensors and saw that proximity sensor is always showing "0" so I can understand why display is turned off. It just thinks that it's closed by something
Can someone tell me how this could be? As I see there are 2 sensors on the one cable: Light and proximity. Light sensor is working ok, but proximity is always showing zero "0". Can someone tell me is this a common situation while replacing a touchscreen (could I just break the sensor somehow) or I might missed some details while i replaced this touchscreen?
Can I test the sensor somehow without touchscreen? (pull it off the touchscreen and try to close/open it by the hand?)

dark screen when have phone call

Hi guys
Since one day , my screen turns dark when having phone call or receiving phone call.
I can't type the keyboard and press the speaker button, which are inconvenient.
I have updated fw to fw_capricorn_miui_MI5S_V9.6.1.0.NAGCNFD_857fde8b41_7.0.zip
I have this issue on different roms including lineage 14 , lineage15, RR,and pixel experience .
Do anyone also have the issue and do anyone know how to solve it.?
My phone drop to ground once which cause screen crack. I am not sure whether this is the root cause.
Many thanks
The phone has on the front a proximity sensor, which is basically a small light sensor that checks if the phone is near the head or not. If it's near the head, it turns the screen of, so that you don't press any buttons while holding the phone to your ear.
I think either your sensor is broken or the crack always brings light to the sensor.

Could I disable this function?
Always disable light sensor or disable when have phone call
I had the same problem I thought the sensor was broken (you can test it with sensors test https://play.google.com/store/apps/details?id=asd.vector.sensor ). But it was ok, it turns out it was firmware related. When I downgraded my firmware the proximity sensor was working again...
Good Luck
