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

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?

Screen locks immediately during calls - proximity sensor not working?

I have two SGS4's. On one, when I place a call, the call screen stays on and it turns off when I raise it to my ear. It then turns on when I pull it away.
On the other, as soon as I place I call the screen goes dark. The only way to get it back is to push the power button and unlock the phone.
The "Turn screen off during a call" setting is set on both phones.
Anyone have any idea what is causing this? Next step is to do a wipe, but that just sucks.
I'm on stock and not rooted.
Thanks!

Sadly I have the same issue on mine but not my wifes.... hope somebody knows something or maybe the rumored update thats going to be coming out will have a fix?? I dunno...

Have you tried doing a reset yet? I'm hesitant since it's a pain to restore everything the way I like it. Definitely a weekend task.

Nope, mine is naked for now. I'll have to do a reset today/tomorrow and see if that solves my issue. If not, I'm taking back to the store for an exchange. It's only been a couple of weeks.

To late for me to take it back but suppose to be a update coming soon that does alot of fixes so we will see Good luck like I said reset I did notice fixed it a bit let me know how it goes I'm threw sprint just curious if you have them only reason I ask if it's just a carrier issue with software or something I doubt it but just figured to see who you had lol

That's what I was looking for!
Sure enough,the proximity sensor was always on and wouldn't go off.
I'm with T-Mobile and they have a 30 return/exchange policy if you buy it outright, which I had, so it only took about 10 minutes for them to exchange it!
Thanks for the testing code! XDA comes through once again!

Same problem when I'm making a call, the screen goes blank when I put it to my head and when I remove it nothing happens.
I tried *#7353# and the proximity sensor goes of but will not stop..
I'm currently rooted, could it solve the problem to go back to stock?

I have had the same problem over the last 3 weeks and decided to take a gamble. I tightened up all the screws on the device and squeezed real hard on the area where the prox sensor is and poof... it works. I have no idea what was up but I feel like the sensor is loose and the pressure resolved the issue. Many other post have talked about cleaning the area over the prox real good and it works but I think its the pressure that is actually fixing the issue. Anyone else have any ideas? Sorry if this was posted incorrectly, I have never posted before but I felt this issue is a PITA.

I have i9500. Unrooted with latest OTA update installed (Build XXUBMG1).
I've been having the same problem with proximity sensor. When proximity sensor is enabled during phone calls (both regular calls and Viber calls), the screen is disabled. Also, my screen sometimes remains on during the call until I place it to my ear and sometimes it turns off immediately during the call. It wasn't always like this, but I can't remember when it started happening, but I suspect it was since the last OTA update.
I've searched around online and have noticed several comments.
Apparently this is an issue with several Galaxy models over the years (sorry, I lost the reference) and this thread: http://forum.xda-developers.com/showthread.php?t=2208440&page=2 mentions Galaxy Note 2 and SGS3 having the issue where there is something wrong with the threshold setting in the calibration settings. Mine appears to have the same issue where it always reads 0cm (i.e. always covered). However this thread also suggests a fix to input some code to adjust the calibration if your phone is rooted.
One suggestion is there is a misalignment of the sensor and so it might be partially covered by the phone's front fascia, causing the sensor to always read as covered or "1" or 0cm. But looking carefully at mine, it looks centred dead-on.
This thread http://forum.xda-developers.com/showthread.php?t=2417401 indicates that the sensor is always on as can be seen through a digital camera LCD (but not with your naked eye). I've tried this with my DSLR and confirmed this also happens with mine, even when the option is set to turn it off during calls, and also even when air gesture (which uses the prox sensor) is turned off. Not sure if this affects the problem or not though.
Can't remember where I read this, but someone mentioned that when shining a bright light over the phone, it works. So I downloaded two sensor apps from Google Play: Android Sensor Box, and Proximity Sensor Finder. And also used the inbuilt *#7353* feature. All three report that my proximity sensor is always reading that something is constantly covering it..... EXCEPT when a bright light (the sun works) is shining on the light sensor - not the proximity sensor. I tested this by using a torch on both sensors. When blocking light from the light sensor, the problem persists, but not when I allow the light to shine on the sensor. So it appears that they both act in unison.
Similar issue with air gestures, which used to work when my phone was new, even in relatively ambient light (but obviously not in a dark room), but now doesn't under similar conditions, and again... EXCEPT when a bright light is shining on the light sensor, or when I'm out in the sun.
Anyway, I'm not willing to root my phone at this point, just to try the fix suggested in http://forum.xda-developers.com/showthread.php?t=2208440&page=2 (my phone was bought overseas and returning it wouldn't be convenient for me). And since this wasn't always a problem with my phone, I suspect it is a software problem related to one of the recent OTA updates.
Edit: After further testing, it seems that air gestures use the front camera as well as the light and proximity sensors.

My proximity sensor works - when I go into diagnostic, it goes green when I bring a hand near the sensor - my issue is that it doesn't seem to notice when I remove my hand and there no longer is anything proximal - until I hit the back button to exit the test. Other than blowing out the earphone jack, does anyone have a suggestion?
Thx.

Proximity sensor
I had problem with proximity sensor in my galaxy s3 mini but my rear camera had error and fc also.I tried everything and nothing work.Finaly I open device and disconect camera and connect it again and camera started to work.But for my suprise proximity sensor now works perfect and I did not touch it.I can't explain what happend but I am happy.

I guess what it comes down to is.....for some you can reset the sensor, for some they can blow it out with compressed air, but others actually have to take apart their phone to fix this issue.

hi
i have the same problem. any solution guys ?
( BTW - im on NB3 INS firmware )

I think I summarized the available solutions just before your post. There is no single thing which always works, you'll need to go through and see which fixes yours. This happens primarily because of hardware, with the sensor getting dirty - so it comes down to how invasive the procedure to clean it.

HOw to solve, none of this works. How cann i clean proximity?

I'm rooted but no idea how to disable proximity sensor

I tried installing the xposed framework but that threw a little notice saying it wasnt going to work. I looked for apps ont he app store but that didnt work as well..
Any ideas on how to disable the proximity sensor so when I turn the screen on it doesnt turn right back off?
Any help is greatly appreciated.

the issue might be your proximity sensor's alignment. it might not have aligned properly. there is a small black rubber holder to hold the proximity sensor. may be you might be missing it or might have loosen it. you can easily fix/align it, if you can open the back cover.
you can install a custom rom to overcome this sudden screen off issue. but when you taking a call your screen will be turning off until other user disconnect the call..
I suggest you fix/align the proximity sensor..
P.S:
There is a small troubleshooting step you can do to see whether your proximity sensor has a slight alignment issue. get a torch or good direct light source and point it directly at proximity sensor. if you can turn your screen on while pointing that light towards proximity sensor, you should have a very small alignment issue. there are plenty of proximity sensor test apps on play store too.

that makes sense.. you also replced front housing too right? that's where that rubber proximity sensor holder attached.. if you replace original front housing with aftermarket housing that rubber holder probably won't come with it. most of the repair technicians don't know this.. if you still have the old front housing you should be able to recover it and attach to your new housing..

Honestly, if its possible I'd rather just disable it completely. I'd rather not open the phone up again if I don't have to and I will never use it for calls anyway.

Poco M3 - Proximity sensor error after lcd change

Hello everyone
I have just changed my Poco M3 's lcd screen (I bought one with the frame already glued to it).
When I turn it back on, There is random messages like "remove your hand from in front of the screen", and when I make a call, the screen remains black, and we can't have access to the screen, in short, the proximity sensor has a problem.
This problem sometimes happened before I changed the screen, but it is constant now.
Does Anyone know if this is a known issue?
Can you help me locate this proximity sensor ?
Is there a plug I did'nt connected correctly, or is it inside the screen?
Can the sensor functions be disabled? In the call settings, I couldn't find how...
If the proximity sensor is really defective, should the sensor allways detec something, or should it detect nothing?
Thank you

Yes.
I had the same issue.
In all the tutorials in you tube they noy showing the rubber part that laying between the proximity sensor and the screen.
So when you are replacing the screen and use a screen with a frame, you need to move the bottom and the top boards from the old frame to the new one, and when you are doing thay there is this tinny rubber, that is probably pop's out when you are pulling the top electric board and you not even know it.
I just realized that it missing until I gave up, and start to clean my working area, and suddenly I sat it.
You can sent me email to [email protected],
I can help you

Hi, thanks for the answer, I just figured this out yesterday, and now mine works too!!!

Try to disable pocket mode in lockscreen setting ...

Thanks for your answer, but my problem is solved, look at Edital1981 post.
