Proximity sensor is not working - Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin

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?)

Need help on disable proximity sensor TP2

Hi
how can i disable the proximity sensor on my HTC Touch Pro 2, windows mobile 6.1 ?
I use a screen lock app that dims the screen during calls but when coming near proximity sensor during call, the screen is turned on again - a real pain.
Please if any onw have an advice to shut it off cpmpletely or when i am on bluetooth i would be really happy for some help
PS i thought paroximitysensor was supposed to disable when tp2 is connected to bluetooth - but its not ??
thanks
Nolan
no one ?
regards nolan
having the exact same issue. I found a cab called TurnOffTheLight but haven't had a chance to try it yet.
For me, it would be better if the proximity sensor was off permanently, if possible.

Hi
could you test teh cab and tell us here if that can turn of permanemtly the proximity sensor ?
regards Nolan
TurnOffTheLight works to turn off the backlighting but as soon as you move the phone the proximity sensor kicks in again.
in the app called Advanced Config there is a category for adjusting the threshold of the Light Sensor. Unfortunately I have no idea how to adjust it (it is at 0 now) and/or if adjusting this would affect the proximity sensor. Can someone comment on this?

Proximity Sensor behavior and solution
I am a late comer to this bb! Hey,I thought all the bugs would be worked out by now! My keyboard did not work right, .... and I have had several other problems with the touchpro2. What are the Chinese doing over there? I had programmed many embedded units and microprocessor systems, but, really, how can they mass produce units like these? Too many cooks in the soup? They are leaving their quality control to the general community.
My problem was I use my gps for bicycling, and if I place it in the support case, the proximity sensor would shut off the screen, even though I was not placing a call. The screen would blank and not come back on. I noticed there was no problem if the physical keyboard was opened and also if the unit were held horizontally. It did this all the time, regardless of the app running.
There are two sensors at the top of the unit: proximity sensor and light sensor. This is a problem with the proximity sensor, at the left.
So I just placed duct tape over it. Now it does not blank.

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 acting weird

Hello,
Since lately, my proximity sensor has been acting kinda weird...
I replaced the camera PCB (where the proximity sensor, camera, headphone, etc. are located), because I thought my proximity sensor was broken (when I recieved a call, I couldn't hang-up(screen went black)). Now I've replaced the sensor, it became one weird thing. When I get a call, I can answer it, and leave the screen on (as long as nothing is in "reach" of the proximity sensor). But as soon as something is in reach of the sensor (cheek, finger, face, whatever), the screen turns black, and won't turn off until the other person ends the call.
I tested this with a app called Z-device test, and with the proximity sensor it shows me that when there is nothing in reach, it says there's nothing (like it should), but as soon as I run my finger across the sensor, it says something is directly above the sensor, and even if I remove my finger, it still keeps telling me this... What to do about this?
same here..almost
i'm experiencing the same problem...but with one difference...
when removing the finger, the sensor just needs some 5 to 10 seconds to detect that there's nothing in front of it anymore...
happend after flashing LeeDroid R5

Proximity Sensor fix

Hello,
after I spent hours with fixing my HTC Desire I wanna share how I made it!
First of all I had the problem that the screen turned of when I started a call.
I checked if the sensor is still working by using a really bright flashlight. ( I just pointed on the place where the sensor is)
The screen turned on again.
So i noticed it cant be broken cause it still responds.
I opened the whole phone (instructions from youtube) and cleaned the sensor and also the window of the sensor. (That was not the point why it was broken)
The seat for the sensor is covered by a small glassy plastic thing, and maybe it went old or whatever but I just removed this plastic thing and now all works fine again.
And for all who dont know the proximity sensor is the one which is closer to the HTC-Logo.
Maybe it helps you.

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
