Proximity Sensor Problem 1.61 :-( Is this the issue?

Hi all again,
I must saw I've NEVER had to do so many posting for a single phone... anyway.
I just updated my Leo to 1.61 via a tortuous goldcard process and the proximity sensor is still not working correctly My wife is the main user of the phone and I was watching her while on a call- the screen was on and off like some demented Xmas lights.
I have a theory regarding the problem. It's only my wife who has the problem with the phone, it's seems ok with me (but I don't use it as much!). The phone is very wide, and the proximity sensor is not central. I think that the sensor is missing her ear (she has small ears!). The gap between her ear lobe top and her head is too great for the sensor. I tested the sensor gap with my thumb and it seems to be around 1cm to activate.
The hardware solution is either move the sensor so it's central (that's not going to happen soon) OR increase the sensitivity of it.
Does anyone know how to change the sensitivity of the sensor OR anyway to completely disable the touch screen during a call.

Hmm I can not believe that, I've tested my sensor:
It put the lights out if i come closer that 1,5 cm next to the screen during a call. So it think this is not the source of your problem.
But: I'm running a 1.48 rom...

I had the proximity sensor behaving eratically upon installing a screen protector. Even though I installed the original HTC screen protector which has 2 holes to position exactly over the sensors but even then I had problems. Ever since removing the screen protector everything is okay again.
Just thought if your problem also coincides with installing a screen protector.
Regards

The problem occurs when your hair overlaps the proximity sensor, the light immediately comes on. Stick the phone back to the ear and the proximity sensor works perfectly on time.
p.s. ive long hair and I too faced this problem and figured it out by running a few test as mentioned above ;-)
Hope this helps.

well, I'm having the same problem and It's not caused because of my hair. it just sometimes works and sometimes doesn't. the test I make is using the palm of my hand. if during one call It's not working, it won't work no matter what you do. then if I make a call and its working, I can turn on and off the screen placing my hand in front of the sensor..

I reckon you clear the area around the receiver and try doing a hard reset.
CAUTION: Take an individual back of your data rather than doing a full backup using some software.

same problem
Hi, I have the same random proximity sensor bug problem. During call accidental hang-up happens every day. I have short hair and no screen protector. Is there any solution for this yet? thanks.
I wrote to HTC already, but they claim there is no problem reported. Sory for my English.

Had a similar problem. My proximity sensor is now working fine. Install the 'Proximity Sensor for Screen Off v0.2' cab. Search the forum for the thread.

thanks for tip, hope this little app will "evolve"...

hi,
i had the problem with the proximite, that it is only working when the phone is in portrait mode. when im incall and portrait i can put my finger to the sensor and it is working perfect. when i rotate the display to landscape the sensor does nothing and the display stays on. unfortunatly i turn the phone sometimes on the way to my ear, and so the screen stays on.
i will try now the mentoined .cab and see what it does for me.
regards mad

(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

Problem with proximity sensor

The problem is that the screen will stay off during calls. That means I can't hang up...
The only way to get the screen on is bright light against the sensor.
Is there any way to calibrate the sensor?

I don't think so. But as you say, it's a proximity sensor, so it should measure a distance and not need light to wake the screen. And as far as I know, the light sensor isn't used in calls.
But you could use the key under the screen to hang up

Yes, that's pretty weird actually, but that's how it is...
But no, I can't hang up since there are no hard buttons. Only the touch-sensetive ones, and they don't work when the phone thinks it's at someones ear.

Screen protector and proximity sensor
I have installed on my HD Mini a very good quality screen protector. During phone call my screen became black like my ear is on the phone, but my phone is on the desk ! If I remove the screen protector the proximity sensor come back to work correctly. Any idea how to set-up or adjust proximity sensor sensitivity ?

Me too!
I have this problem too!

Your phones have a screen which is made of really good strong glass. Using a screen protector is useless. I have had a Hero (also a capacitive touchscreen phone) for 6 months and, while I do keep it in a holster, I have rubbed it on my shirt, dropped it and used my finger on it all day long. It still is spotless. Stop wasting money on protectors and just use the phone. And having a protector is bound to screw up the proximity sensor.
As far as it not recognizing that the phone is not against your ear.... that is a matter for the service department to solve since it seems like a hardware fault.

Really strange! I've a screen protector but don't have this problem... the sensor works fine!!!

It's made out of plastic, really easy to make scratch. And it's very fingerprint attractive. So glossy filter is really good solution.

Same problem, proximity sensor work really weird.

Hi guys, I have the same problem on my HTC HD Mini, when you make a call the screen goes black and will not allow to end call. I have to take battery out to make it work again. I was looking at the registry tweaks for HTC HD2 (leo) and am wondering if those tweaks will work on my mini.
Please, if anyone has a solution, put it on here, have even tried replacing the glass to resolve but not working still.

Same problem. I tried an experiment... when i'm in a light room, works. when i'm in a dark room doesn't work. Really stupid... without light doesn't work!!
If you would, try to put the mini under light when is in calling...

In fact, that's quite normal. If you're calling in a dark room, how do you expect that your phone can "see" the difference between the darkness of your ears and the darkness of the room?

Are you using a screen protector?
I used to have the same issue. But once I remove the screen protector the screen turns back on straight after a phone call.
I believe that the proximity sensor is confused and is affected by having an object pasted over it.
so if someone could experiment with just removing he corner of the screen protector to avoid the sensor, you will not have a issue.
I am using the mini with a screen protector and it has been fine in my pocket...but I am not saying you should try!
My 2 cents!

its made of carbonized whatever mixture just like any other capacitive screen and no theres no way to scratch that thing, iam wearing it in a pocket together with my keys since i bought it and theres no single scratch there, yet the fingerprint thing is very annoying indeed but thats because the material of the screen is very very close to glass.

The lcd and digitiser have been replaced and there is no screen protector on the device. I purchased the lcd and digitiser as a complete unit so as not to have any issues.
The seller reassures me that the product was brand new and had been fully tested. I no longer have the old pieces to test against but this problem seems quite common from the threads on here and gsm forum.
Any solutions or ideas for resolution greatly appreciated, near to pulling all my hair out!!!!!!!!

I have screen protector and I do not have any problem with sensor. Everything works great..

i have the same problem as you.. when i am in a call i cant end it because my screen is black all the time.the only solution i found is when i call i turn the speaker on.please help us
p.s where on the screen is the proximity sensor??

Yes I know... I meant that only works in bright light conditions, such as directly under a lamp or sunlight. in a room or just the shade does not work. So it's "only"a matter of adjusting the sensitivity of the light sensor. I do not even understand how it can be made this "proximity sensor", all I know is that it works with light. Rather, there is a program like the shake'n wake can use?

I have this annoying problem, too.
But I have to say: I have NO screen protectror, and: the divece was repaired by arvato-Services after a broken display. And I didn't have this problem before!
Sometimes i seems to help to puff serveral times into the loudspeeker, so that the screen returns and I'm able tu hang up the call. But sometimes it doesn't works, and if I had spoken to a mailbox (and the other end didn't hang up, so that i MUST hang up) the last solution was to remove the battery.
If there is a way to disable the sensor (i.e. in the registry)?
kind regards

Ye same thing, Mine will only bring the screen back during a call if it is under a very bright light.
Any ideas yet?

[Q] Screen goes black when I make a call

My nexus 4 Lollipop 5.1 Seems to have a problem when I make a call. I hit the phone symbol, select the number I want to call from my requent call list. I hit the dial button and make the call........ The problem comes when I go to end the call the screen goes black such that I can end the call. I just have a black screen........
Does anyone out there have any idea whats happening and what the fix may be?
Thanks for any help

Remove your screen protector.

The screen is supposed to go black when you make a call--or, rather, when you place the phone to your ear. There is a "proximity detector" along the top edge of the screen, and it detects your ear when your ear gets close. The phone then turns off the screen sensors so that your ear or your cheek doesn't push any buttons while you are talking, and turns off the screen illumination for aesthetic reasons. However, the proximity detector is supposed to cause the screen to turn back on when you remove the phone from your ear. That isn't happening for you. When it didn't happen for me, I took it to the shop. The tech said the proximity detector was broken, and ordered a new one. But replacing the proximity detector didn't help. He finally disabled the sensor so that proximity was never detected. that worked.
This story does not have a happy ending for me. The phone worked for a couple of days. Then I tried to reboot, and it went in to a boot loop. None of the standard cures for a boot loop is helping me. I doubt if the two problems are connected.

Proximity sensor turns off screen when you put it to your ear to avoid your skin touching the "End call" button or something else

Ok, was worth a shot...
Then you must likely have a faulty proximity sensor, as stated previously.
Download an app, like AndroSensor, and see what the output for the proximity sensor reads. When nothing is covering the sensor (top left corner) it should read 5 cm/2 inch, or something similar. If it reads 0, it's busted...

I did as you suggested and the results say 2" uncovered 0 when covered

Hmm... The plot thickens...
That means you have a working proximity sensor. No idea what it could be then.

I'll keep looking for a solution.......... It's a pain especially if if I have to respond to a VM and hit a Number.......

I have the same issue. In my case, the proximity sensor may have been broken or blocked by dust.
My "temporary" solution is using the power button to disconnect calls. While using a Bluetooth headset, the screen can be turned on. I hope there is a better solution.

Please help! How can I keep screen on during call?

So I broke the screen. replaced it and it worked fine. However i noticed the adhesive wasnt holding it tight enough. so after a few days I pulled the glass up as munch as I could and used some superglue on the top and then clamped down to hold in place. Now no more light is coming through but.. When I make a call as soon as a i press dial the screen turns back regardless of my distance to prox sensor. I'm assuming I got glue on it or broke it.
Eventually I will replace LCD but in the meantime is there any way to simply have the screen stay on during callsly ap?
I tried a few apps which did nothing. I looked for settings but nothing jumped out at me. I swear I have done this before on either an iphone or a much older android device.
Any suggestions would be great appreciated. Right now by using switches under accessibility im able to hang up at last but I cant turn on speaker and not sure how to set that up. So if there isnt a way to keep the display on any suggestions on how to set up so I can hang up and turn on speaker phone in the most effiecient way?
Its gotta be built in the system to keep the display on during calls but maybe not.
Again thanks!

There used to be an Xposed module to disable the proximity sensor on some SoC... But it is VERY SoC dependent from what I understand... And it may not be supported anymore...
Your other alternative would be to disable the proximity sensor in the kernel... I know it CAN be done... But I have no idea how
