Hello to all...again !!
Recently, i broke the digitizer flex cable and the antenna cable connector so i had to
replace both of them. I did. Antenna works great, digitizer works great..the only problem
is the proximity sensor.
I have disassembled the device several times and if i'm not mistaken the proximity sensor
is on the digitizer's ribbon cable. Is that correct?
Anyway, everytime i make a call, the screen goes black and can't turn it on. No way to NORMALLY turn it on.
the only way i've found that turns on the screen, is if i put the sensor in front of a light i.e a lamp.
Furthermore, when i go in the service menu ( *#*#7378423#*#* ) and do the proximity switch test it defaults to on
when i think it should default to off (because at the time i'm starting the test, there's no obstacle in front of the proximity sensor).
when i move the sensor in front of a light, the test gives me a sound and the value changes from on to off.
So i'm thinking that there is nothing wrong with the hardware. They didn't send me a flawed digitizer, did they ?
Plus, is there any config file or driver responsible for that sensor ?
Also, i searched xda and found this http://www.youtube.com/watch?v=uMk1S90MjbY for motorola defy. Is there
any workaround like this for the neo v?
Thank you very much for your time and assistance.
bump?
The proximity sensor is on the right corner, between front camera and the right corner.
Check again the position of the sensors beneath those two black piece of plastic.
The items are, from the left to right:
- speaker;
- light sensor;
- front camera;
- two viewer for the proximity sensor.
@ciubexx
thank you for your answer.
I checked the sensors and are correctly positioned but the problem persists.
Again, if i put the device under light the sensor seems to work.
Also, i've downloaded "proximity sensor finder" from google play and it seems like
the sensor is constantly covered. I did the test without the front housing and the same
happened again.
Also, i have a problem with the earphone. When the front housing is attached the volume is
very low but when removed, the volume is normal again. What could that be?
Thanks again.
edit: everything solved. disabled the sensor and removed earphone's cover from front housing.

How did you disable proximity sensor?

Right after I replaced the rear camera in my phone it seems like the proximity sensor died as when I try to call the screen immediately turns off and locks until the call has ended.
Proximity sensor finder indicates that there is an object 3cm away but there is nothing actually there and the indicator is just stuck on 3cm.
What should I do?
I'm on cm9 btw.
Bump
Same issue
I have my stock camera and run CM9 AOKP, and I have similar issues with the proximity sensor. I read somewhere that it was an issue with CM in general and always discounted it as such. I did set up volume rocker wake and use that to wake the screen on call.
Do you use facelock? Try disabling it. Its a well known bug in CM9 that effecting proximity sensor...

Using the volume buttons doesn't wake the phone.
Note sure what facelock is.
Thanks for the answers.
my wifes proximity sensor started acting up along with many other problems. this all happened right after the last OTA update. I sent it in to moto for repair. I was suprized i didnt need a reciept. I bought it on cl used. went to motos site and they showed me how to check if warranty was still good
Phone was imported so no warranty is available.

Ok, I figured and putting the proximity sensor really close to a light source makes the screen wakes.
Also, using proximity sensor finder I did see that the proximity sensor responds when putting it really close to the light source.
It seems that while replacing the back camera, the rubber cover of the proximity sensor fell off. Is there any way I can replace it or improvise something that might suite?
Thanks.
Hi,
My gx2 was running cm10 and everything was working fine up until recently when my lcd screen broke.
So I ordered a new one and replaced the broken one, the repair has gone well , also the screen was good. Except there was a problem with the proximity sensor, when i tried to make a call the screen would go black and not switch on again, the only thing I could do was to take out the battery.
So I thought maybe I damaged the proximity sensor somehow while replacing the screen, so I bought a new sensor. The same Problem.
So I thought maybe it was firmware related even though I did not change the firmware and before the screen broke everything was working fine.
I flashed a stock rom, again everything went well , phone was working except the same problem with the proximity sensor.
Anyone know what that could be? Could I have damaged the motherboard somehow, even if that is unlikely because I was always extra careful and patient.

1. You should check if the sensor is really damaged. You can use e.g. Android Sensors app from Play store.
2. If it is broken, then try to disable it in ROM settings. I think there is at least an option in phone/dialer settings.
Maybe that can help.
Good luck !

I know how to disable the sensor, when I disable it calling works, but I want the sensor working . The thing is I thought I damaged it while replacing the screen, so I bought a new sensor, but the problem is still there.
android sensor box shows me a value of 0,0
typing in *#0*# and then "sensors" : the screen is always green an the phone is vibrating PROXIMITY: 13
the phonetester app shows Proximity sensor :near
I just figured something out.
The proximity sensor works when I hold the phone against a light source, when i do the *#0*# test and hold it against the light, the screen turns to white and the sensor works as it should( when i hold my hand near it, screen switches green and phone vibrates) , but only as long as it is near the light source.
Could the sensor just not be calibrated correctly? Is there a way to calibrate it?
than you
Hi,
Recently I have replaced my Xperia mini pro's ribbon... May be you all know that this ribbon contains proximity sensor, front camera etc.
After the replacement when I'm making a call screen went black and it dosent turn on when phone is away from the ear.. I have checked on service test menu and proximity sensor is always read as "On"
Does anyone know what should I do???

Bringing this thead up again because I am having the same issue, Proximity sensor set to near all the time... could it be badly placed? I was ever so careful to get it millimetrically perfect..
something must be causing the sensor to read an input all the time. Ever considered there could be some dust below the glass? Try and see what happens when you take the screen assembly away from the sensor. Another cause would be a deffective part (bad ribbon/flex components).
Thank good lord I managed to buy a genuine Sony flex ribbon
Another thread about this stupid sensor.
My screen goes black when I call or answer a call. If I use a headset sometimes randomly the screen comes on or stays on when I answer a call.
The proximity sensor is working. Looking in *#*#7378423#*#* > Service tests > Ambient Light Sensor.
Putting it to a lamp gives a value of 10.0 and putting my finger over the sensor gives 0.0 .
So its working.
This seems to not be rom related if not for the change after Android 4.4. I flashed roms from cm-12.1-20161016-NIGHTLY-togari.zip, AOSP_N_161207_togari.zip and now I am on hybrid_concept_edition_2.0.zip.
I do have a screen protector on. But with a hole for the sensor. Its not dirty in that area. And the sensor worked fine way before I installed it.
This started happening during the last two months or so.
I tried numerus of apps from play store. None did anything. Of course I could force the screen to be on. But with the risk of pushing some buttons when I'm in a call.
My temporary fix so far has been to enable end call with power button
Do you have any idea what to do?
Thank you
I'm facing this same problem, I'm on stock.

yup.. I had mine apart today. But you need to remove the battery in order to flip the motherboard around to get to the connector.
I don't have time for that. Perhaps the battery will explode if I try to remove it..
So I cut a piece of foam plastic to fit around the usb connector so there is a constant pressure applied to the motherboard when screwed down the NFC antenna because there is a screw just around this area that sets the NFC antenna in place.
Hang on. I just made a call just for the sake of it that you answered to my thread and it freakin works!!!!!!!!!!!
I got the idea from this guy/gal: https://forum.xda-developers.com/xp...olution-proximity-sensor-fix-z-ultra-t3595525
Hi,
I have problem with the proximity sensor, that automatically start other calls.
How can i solve the problem?
tks
I don't know if it can be calibrated or there are some rom where it works better, what I do to mitigate the problem is turn off the screen after I answer/start a call.

Why are you convinced it's due to the proximity sensor?
The proximity sensor does nothing during a call other than turn off the screen when the speaker comes close to your ear.

Probably because screen stays on during a call and you do all sort of crazy things with your ears.
Calibrating proximity sensor from my experience does very little to help with this problem.
What @MrCrayon suggested is probably the best solution

So the problem is that it doesn't turn off the screen and touching your face to the display triggers what you don't want.
The proximity sensor of our phone has a very narrow detection area. The space is located in the area below the top speaker outputs (top left). The ear should preferably be attached at this point during a call. So not in the middle of the top edge of the phone as usual. It is definitely uncomfortable. In addition, the sensor is less responsive if the phone is not in a vertical position. The proximity sensor is probably the biggest weakness of this phone.
The best way to check its function is to use the AndroSensor app.
