Proximity sensor problem - Zenfone 2 Laser Q&A, Help & Troubleshooting

On all the noughat roms i've used i'm having an issue with the proximity sensor.
The problem is, whenever I call someone or pick up a call the screen goes black.
I changes the settings so that pressing the power button cuts the call, but i can't put the call on speaker cause i can never see the caller screen, because of this problem.
Please help.
Thanks.

Also i'd like to mention that I've tried the method in which you push a reconciled apk through ADB. This method used to work, but that stopped working.

proximity sensor issue when calling

Hey guys.
Its starting to bug me more and more that sometimes the proximity sensor on the HD2 when in call mode it does not shut the screen off.
this means that i some how have managed to enter the mode to switch my phone on to flight mode mid conversation.
i notice it happens more when the battery is getting low (less than 15%).
its an issue as when i am talking to customers, i end up speaking to myself for a few seconds before i realise my phone has turned itself in to flight mode
has anyone else had this problem ?
proximity sensor when receiving calls
Hi adam
I have been having the same problem, when i make a call the screen goes off, but when i receive a call it stays on. I have tried putting my finger over the proximity sensor but this doesn't make any difference. Its starting to piss me off having to close everything that has been opened by my ear while on the phone.
Hopefully someone can come up with a solution for this.
Hi, I have that problem randomly both when reciveing and making calls. The workaround I do is when making a call I press dial and the put it in speaker mode until I can hear ring tones then I switch back from speaker mode. This works everytime. I would, of course, like to have it working as it should but for now....

Last time I had the problem turning the phone upside down and back helped. G-sensor seemed to affect screen blanking. But I didn't have the problem for some time.
Well I had the problem today, but I dropped the call unintentionally before I noticed, so I could not check this theory.
hi,
for me the sensor stops working when the phone application is in landscape mode, because i hold the phone more like landscape then protrait. so after i figured this out i make sure to hold the phone in protrait bevore moving it to my ear, since then the proximite sensor is working fine for me.

[Q] Screen won't turn on after a call ends

Hey,
I have a weird issue with the proximity sensor.
When I answer a call, the screen turns off as usual, however, every now and then the screen won't turn on after the call ends. The phone is still responsive however, and pressing the power button simply gives the lock sound.
I'm using CyanogenMod 6.1 Nightly 85 but I'm fairly certain it's happened before on other roms as well.
Any ideas?
That Problem I've sometimes too! Dont know to fix it...

[SOLVED] cannot hang up during call

I noticed this problem:
when i start a call, my screen become black and i cannot hang-up the call.
anyone with same problem?
another little question:
i have a time-limited data plan (40H /month) is there a way to know if my HD2/WP7 phone is connected or not? or a way to control my data connection?
thank you!
I have the same issue. If I hold the proximity sensor directly to a bright light source the screen comes back on but I'm not always near a bright light source. I've been making calls on my bluetooth headset because that has a hardware hang-up button. If someone could work out how to hook up the hd2 hang-up button this would be a massive help...
EDIT: i make some test, plese discard this post (test result in post #5)
I'm not sure about yours, but after I finish my call I just remove my phone from my ear then the screen show up . Regardless where I am (dim or bright place) the screen responds to the movement of the phone away from my ear .
ok, i make some other test.
confirmed, we have some problem with proximity sensors.
when i make a call, the screen become black. immediately, witoutn anything else.
wen i remove the phone from my ear the screen will NOT come up UNLESS the other part hang up.
for example: if the other part use an answering machine, i am able to record my message, but the screen DOES NOT comes up when i remove it from my ear.
if the other part is a friend, and HE hang up the call, my screens lights up, again, sayng "call ended". then return to the home screen.
if i'm in-call, and i expose the phone to a bright light, the screen comes back too, sowhing all in-call options (speaker activation keypad, and some other things)
Just press the normal hang up button and that should act as the power button to bring the screen back on...

during call this button doesn't do nothing.... already try with all button..
i just play with registry entries, some are interesting.
HKLM\Drivers\Builtin\Proximity
ScreenOffDebounceTime DWORD:50 (Decimal value)
ScreenOffThreshold DWORD:256 (Decimal value)
But i cannot figure how they affect screen (i try to change their value with no effect)
update:
seems i fix it!!!
after an UPGRADE (hehehe) to winMo 6.5, i realize that problem still exist.
then i remove a portion of the screen protextor and proximity sensors works again!
even if i use original HTC screen protector... :\

I've tried that already but it didn't work for me. I did have my screen replaced so I wonder if the problem started then...
Same to me... Is this a replaced screen issue?
Strange one this...the red button (bottom right of the 5 physical buttons) just brings the screen to life for me and should work I would have thought regardless if screen is replaced.
hey guys i am facing a problem too with my tmous hd2...i have dual booted it..when i make a call in android or win7 proximity sensor doesnt turn off the screen at all.....so i end calls without my knowledge and intent.....anyone facing similar issues??? anybody knows any solution???

[Q] Can u tell me what the file of controlling Proximity sensor,tks in abvance==

what is HD2' file of controlling Proximity sensor,Can u tell me the detail ?tks in abvance==
My English is very bad,Many do not understand
I also have problem...
Hello, I would also like to know the answer to this or if someone knows how to disable the proximity sensor
I have problem with the latest builds, currently I am using BOYPPC_SHIFTPDA Ginger.S. Almost everytime I start dialing the screen goes black and the phone locks. I can finish the call but the phone remains locked - black screen with the buttons light on.
I manage to wake it by calling myself from another phone and and sending busytone or by pluging in USB.
I managed to be able to wake the phone up with a program called Sanity. But I still cannot wake the phone during the call, for example to send DTMF tone.
This seems to be connected with the proximity sensor. When I check the status it isn't giving any values, or sometime gives some random values. I think it isn't broken because sometimes it works well.
I haven't had this problem with MIUI builds.
So probably removing the proximity sensor drivers would solve it
also have the same problem. Ending a call makes my phone keep its screen turned off... Until i find a lamp wehere i can holde the sensor under it so that it turns on the screen again.
I'd just like to have an option so that the screen doesn't turn off in a call. I mean it must be possible to deactivate the sensor...
Just press the middle button - the win flag button - and the screen goes on again.
not easy as that the phone doesn't react at all. Hardware keys lighten up but screen stays black. Looks funny when you search for a bright light source just to use your phone again after a phone call .

[Q] Can't access phone during call, need help!

Whenever I start or answer a phone call, my screen goes black and will not turn on until the other person hangs up. I just recently found on my ROM that I can set the power button to end the call so I have been using that, but I cannot use the keypad to type passwords and it is very frustrating. Any ideas on what could be wrong? I am currently using the Black Edition PACRom for the s4, but the problem also happened when using the standard cyanogenmod. I am thinking that maybe the proximity sensor is screwed up but I am just very frustrated about it. Any help would be great!

I think it is the proximity sensor, I had the same issue and what I did is to replace the glass and making some enlargement near the proximity sensor in order to have more blank space around.
you can see it in the photo.
With stock rom, things goes find, now the screen goes black only if i place it on my ear, but with custom rom, i can not hang up calls even if i press the hang up button, call still continuing.
Sorry, if my english is bad, i am a french speaking.
