Proximity Sensor help needed!

Hi all,
I think my Proximity sensor is broken..... can one try the following:
*#0588# (Proximity Sensor Test Mode)
And tell me what happens when the sensor is covered?
Also anyone got suggestions on how I can fix this?
Thanks
Tony

It works for me with *#0*# then select sensors and then move your hand close to the phone.
It also works with your code, the phone vibrates and the background changes colour when my hand is 5cm above the sensor.

Can you please tell me what it says in Sensor?
In Proximity Sensor I have:
Proximity Sensor (Min/Avg/Max)
------------------------------------------
PROXIMITY: null ADC: 0 (0,0,1)
and sometimes when I cover the sensor it changes to : ADC: 2 (0, 1, 2)
Thanks

Looks like it is broken ACC 78(83,85,89) with my thumb over the sensor.
The important number is the first number (78). This must go over 10 to register as near at about 5cms , then the background turns green.

Thanks for that. Do you know if it's a firmware (I do have original Firmware on it but had CM7 on it for a while)

Looking like a faulty phone to me. These are hardware sensor tests.

a friend of mine has the same problem. We bought the telephone together but , after 1 month, his proximity sensor stopped working.
We tried the samsung diagnostic tool receiving the same information (ADC reach maximum 4).
we noticed that it stopped working after the change of the rom (with the installation of the clock recover) but I'm sure this is the real cause.
Is there a configuration file where proximity sensor parameter like gain/offset are stored?
Maybe some buggy application has changed these values.

if you have no warrenty, you can buy a replacement sensor, only about £10, it's front cam/sensors in one component

problem fixed!
Using phonetester it took 5 minutes to connect to the sensor (while with my phone it took 1 minute) but once connected , the proximity sensor started to work again also with samsung diagnostic and phone application.

Proximity sensor problem! [SOLVED!]

Hi everyone, welcome to the next thread of mine where I would like to share with you an interesting case of a'faulty' proximity sensor. The issue with the sensor started a few weeks ago (I own my defy for a few months) and the problem I had with it was that sometimes during I was making a call the screen was not being turned off, and more whats more annoying - the screen was never turned on again after finishing the call.
I do not have a screen protector and the screen glass is original.
I downloaded an application that showed the state of the sensor and after a many examinations i found out that many times the sensor does not distinguish between the states of being covered and uncovered.
I tried everything - factory reset, clean installations, different ROMs - nothing helped. The only thing that helped a little was a tweak availale in the CM7 ROM by Quarx (not available in the STABLE CM7 though!) in the screen settings menu -which forced the screen to be turned on after finihing a call, and I could also set the power button to end a call in the accessibility options. So this helped but did not solve my problem.
Fortunately, after many questions asked on so many threads, the user monecafe PMed me with a link to a video where its clrealy shown what is the problem and how easy it is to fix it!
without sayng more - here is the solution for anybody experiencing this issue:

I hope this helps !
& a BIG THANK YOU to monecafe who sent me this video

this is great, very simple solution but...
how will that affect the water resistant feature of our defys?

try turning off auto-brightness
posting to say... try turning off auto-brightness (worked for me)

I used to have this problem. Stable CM7.2 solves this issue for me. I used to get the screen to turn on before by just rubbing the area with the proximity sensor with my thumb as if it was dirty.

i still have this problem. , after the Waterproof failed with my phone ( i dont leave it in water, i just wash it !! the proximity sensor failed too when i make a call screen is black cant see anything..so my question is if i change the screen touch proximity sensor work?? or its on the board ? where is the proximity sensor place?..how can i solve this problem by myself.
i saw the video but not solve the problem..
i back to stock ROM _there_ if i press power button the screen back but in coustoms ROMs the screen off not back till remove the battery!! any software make screen on at call and disible the proximity sensor ?
thank you inadvance

CAN I GET THE TECHNICAL GUIDE(MAP) OF BOARD?

I also have problems with proximity sensor. With pressure on the screen where the sensor is located it is working again.
So I can believe that changing the screw pressure might solve the problem. But what is the initial reason for this? It is not a pressure sensor!

Hello All, I've been using the proximity sensor app on my DHD for quite some time now... LOVE IT ! However, now when I open the app & tap on Start & cover the proximity sensor on the phone, there is NO RESPONSE... Meaning the msg stays FAR... It DOES NOT change to NEAR.... Can anyone help me out ? CHEERS !

Found a possible Solution suggested by a supplier on Amazon;Switch off the phone - Hold power button & volume down button
simultaneously to bootinto factory testmode - use volume swith toscroll thru to 'test report' - select with the home key - scroll down to 'PS calibration' - select it then scroll to 'do calibration' let it do the calibration till it gives OK.Go back to 1st menu & reboot.
Was only partially successful forme, it may work for you.

Is this applicable for Motorola Defy or for the Chinese clone?
I tried this on my Defy running JB 4.1.2. I cannot get into the "factory testmode" even after pressing the VOL down key at boot up.
I just get a screen with an exclamation and the android bot.
Nothing happens after that.
BTW: What size of screw driver should I use to perform the trick in the video posted by the OP.

Not applicable to original defy

Hi guys is there a tweak someone created or exists that can disable the proximity sensor on the s4? Is it possible? My proximity sensor has issues where in a call the screen goes black and doesnt come back on even if i press the home button or the power button and its really frustrating. Ive seen some posts about going into mobile terminal and changing things but i could never figure that out i would like it if someone could explain how i can disable my proximity sensor thank you

Need Help related to proximity sensor

I am using zenphone 2 laser ZE550KL and yesterday my touch pad got crack... and thats why my proximity sensor not working properly as broken glass is on the sensor... so i wnt to disable is completely... i mean it is like my phone doesn't have proximity sensor... any guys help me out here.... the only solution i have in my mind is to open my phone's motherboard and remove the proximity sensor... But i don't wnt to do that... i wnt to fix it by only software... plz help guys.

You should bring your phone to ASUS for glass fixing
If you using LineageOS, go to Settings => Buttons => Turn on End call by Power Button. This may be helping for a time

Dude i don't have problems with calling... but my double tap to wakup not working also when i am using third party apps like messenger imo etc my screen goes completely black... then i have only one option to restart my device

You can find the proximity sensor file in your root folder, maybe if you delete it or renamed it, it will disable the sensor.

Where..
