(Video)Proximity Sensor Sensitivity Problem (TMOBUS HD2 vs HD2)

i think my proximity sensor is too sensitive because it ONLY works normal when i am outdoors at direct sunlight, but even when my shadow drops on the sensor it locks the screen, also in shade or in well lit indoors my proximity sensor doesnt work properly either.
i want to know if there is a way to change the SENSITIVITY of PROXIMITY SENSOR at will? i removed the screen protector so there is nothing on the way of the sensor.
also during a call pressing hardware buttons doesn't bring the device back from standby, hardware buttons are lit for a split second and nothing happens. is there any way to use the hardware buttons (except "end call" button of course ) during the call to turn the screen on?
t-mobile us hd2's proximity sensor works fine but mine has a problem, see the video here;
http://www.youtube.com/watch?v=OKCRqFYtLMs
thnx for your help..

Any idea?
Any idea? Does anyone have the same issue? Plz it's a very irritating problem I couldn't find a solution..

I havent own HD2, but eventually I will get it this year.. So, I wondering why you removed screen protector? because of sense Ui wont work with screen protector?

I removed the screen protector because I thought that it blocks the proximity sensor and cause it to malfunction, I searched the forum and some people had the same problem but solved it by removing the screen protector. But it didn't work in my case so I'm looking for a solution.
As you can see on the video the proximity sensor works normal under direct sunlight when i move it to the window, in the room it somehow doesn't work correctly..
(english is not my native language so pls excuse me)

Thank you
Thank you for your creativity with subtraction

Sorry for disturbing again but my problem is killing me i am desperate to find an answer could you pls at least share some ideas or recommend something to do?

İ emailed HTC for the issue and waiting for an answer, if you have any idea pls feel free to share i'm stuck with this annoying problem, thnx..

HTC's response
I do apologize there is no way to change the sensitivity of the proximity sensor on your device. You can try a soft reset by pressing the reset button on the back of the device. If that does not resolve the issue then you may want to do a hard reset on the device. Hard resetting the device will clear off the device and reset everything back to factory settings. You will want to back up your information from the device before doing the hard reset. If the hard reset does not resolve the issue then I suggest contact our support department..........

I guess I'ıı have to get the proximity sensor changed..
I searched eBay for a replacement but couldn't find it there are proximity sensor replacements for iPhones, I wonder if the iPhone's and HD2's sensors are the same?(probably not but I just want to be sure)

Hi a have the same problem. Did you found the solution?

well the promicity censor has nothin to go with light or shadows..it could be a glitch in the Radio or ROM try using a new radio or ROM

How to set Proximity Sensor Threshold on Mango?

Hello fancies!
I'm having some problems with the proximity sensor of my Omnia 7. Basically the values from the proximity sensors are a little bit off the usual and the screen just goes black when answering a phone call ( so I can't hang up anymore, for example ).
I tried the diagnosis menu and the LCD test screen. There I can see the proximity values and understand why the phone is behaving this way, but there is no "SET" button as a lot of guides on the internet say.
My guess is that that button is gone with the update to Mango. Anyone can confirm me that and give me an alternative diagnosis screen where to change the value?
The screen I'm refering to is: *#0*# from the diagnosis screen.
thanks a lot!

up... any ideas?

maybe a dumb question- have you a new screenprotector, with covered
Proximity Sensor

the sensor is in the up-right corner
so maybe holding it with right hand you cover it and screen goes blank
happens to me...

it's not what I asked.
I know where the proximity sensor is and how it behaves, but when I replaced the screen something went wrong and the default low threshold is too low to work properly right now, so I have to set another value.
This was possible on WP7, but apparently it's not in mango. Do you have any idea where I can find that setting on mango?

has anyone got an answer to his question?
it seems that there isn't the set function in the diagnosis mode with mango anymore ..

me too have same problem.i just change my lcd screen after it happen when i make call screen is going black andi can't do anything no any button is not working.
there is any way to set promixty sensor on mango ?
or any app for this ?

flash a pre-mango ROM and change the value in the diagnosis app, I'm not sure if it will stick when you update, but it is certainly worth a try.

You can try reinstalling diagnosis app if you haven't yet. Maybe it works.

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!

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

Torch help

Hello. I recently replaced my nexus 6p screen and now surfer the dreaded proximity sensor problem. On 7.1.2 i was able to use torch when longpressing power button when screen is off. (this is via custom rom function. No tasker) now that ive upgraded to oreo, that function is gone even if the rom supports the feature. Im guessing something to do with prox. Idk. Anyways can someone guide me into making a task profile/task that whenever my screen is locked or off i can use torch while long presing the power button? Thank you so much.

Not sure if you read into it, but the broken proximity sensor problem after screen replacement is likely due to a missing rubber grommet over the prox sensor. It falls off or sticks to the old frame. Can't help with Tasker tho

Bollux. Any other work around while im on lockscreen? I mean i know a big change happend from N to O but that big where i cant utilize torch because of a proximity problem? N didnt do it Why does O have to. :'( i mean even with the broken prox on N i was able to utilize torch while screen was off.

Not sure sorry. I have used Torchie from the play store. If i remember right you turn on torch by pressing both volume buttons

I guess my dream of making this work is crushed. Please delete/close this thread mods. Thank you very much.

Trying to find Xperia Z3 proximity /dev??

I am having issues with my Z3 proximity sensor being activated when it's not supposed to.. e.g. when I receive a call the screen will just go black and I cannot answer the call or even see who is calling me, same when I dial out, I just have to hope the other person hangs up or I have to soft reset my phone with power + vol up until it turns off then restart.
I have tried all the silly apps and none of them work, or they are just bloated with ads etc. and besides I would rather not have to rely on an app for this. I have read in a few places that the proximity sensor is at /dev/cm3602 but only on certain devices, and possibly only on ICS/JB.
Surely there must be a way to disable the proximity sensor via root shell?
I have tried so many things, at first I thought it was a firmware issue, but after trying various ROMs I figured it's not. What confuses me is that the proximity sensor and light sensor are the same sensor, and the light part works fine but the proximity doesn't.
Is there anyone out there who knows anything about this? Has done this before? Or is willing to give me any idea on how to get going in the right direction?
Cheers in advance..
