[Q] Dresire S - Proximity Sensor Problem - HTC Desire S

Got a brand new DS couple of days back and....right from opening the box..the first call..proximity sensor is playing up. Most times i have to pull out the battery to end the call.
Tried the following with no result
1) Installed DHD Proximity re-calibrator
2) Factory reset
3) Installed Vitrous Unity 1.27
4) Back to factory rom, blew hard between ear piece and sensors
5) Removed screen protector and tested
I have S- Off and really dont want to go through the pain of visiting HTC. Would greatly appreciate some help here ...as always !

did you press the back button in between the call?
this has happened to me on stock rom only if i press the back button during the call
i haven't tried it on LBC rom yet

I noticed that only half the proximity sensor is visible, the other half is covered by what appears like black plastic part. Is this how it is supposed to be?

My proximity sensor is completely visible.

No..i haven't pressed the back button.

Is it the left sensor of the two sensors?

I have exactly the same problem. The issue seems to be that Desire S proximity sensor active distance is 9cm, when on my older Desire ir is only 1cm.
When working with some Proximity sensor tools, I have discovered, that you need to put your phone like 25cm (have no idea, how many inches) away from any obstacle in 30degree radius. If that is followed, I haven't been able to recreate a battery pull ocasion of sensor failure. However in real life talking, it is impossible to guarantee.
That there must be some sensor configuration possibilities, so that we could decrease sensibility to minimum distance. Such change should solve this sensor bug, as it would be normal operation distance.
Maybe some dev knows, how to play with proximity sensor?

Yeah, I have had this problem a long time with this phone didn't happen that much at first then it became more and more apparent.

Found the problem and solution, it lies with the screen protector, yes it might be transparent but the sensor detects it. Using a sensor testing app from the market it suggested the sensor was covered almost all the time.
So the solution was replace the protector with new one but cut an arc at the top just big enough around the sensor at the top left, easy fix now in call screen is more responsive.

Proximity sensor
I've been having the same issue. I gave my DS to the HTC workshop and they said it was faulty hardware. They will be replacing the system board since the sensor is soldered to it (under waranty).
Before sending it in, I tried a few roms and hacks but it was never resolved. I recommend you visit your local HTC warranty center.

I have the same problem with the proximity. I installed an app called Anyunlock which seems to have solved the problem. It seems to be able to wake it when the screen turns off after a call. The app allows you to unlock with the volume key and replaces the lock screen with its own. I hope this keeps working

broken proximity sensor

So I have been having this issue lately where after calls, my phone's screen wouldn't wake up.
I just discovered that I may have a broken proximity sensor?!?
I've been trying different roms and such to see if it would help and finally decided to download some tools that measure and adjust the proximity sensor and noticed that it will discover "far", then "near", but gets stuck on near.
Can anyone confirm that on their Sensations, it goes back to "far" when your phone is moved away (or you move your finger away)?
What kernel are you using?

Currently, Faux with Revolution. Tries IC with stock as well. Same thing.
The strange thing is that if I restart the sensor app, it will go back to default.
That's weird. I was asking because if I'm not mistaken, bricked kernel was having wake up issues that were fixed on the latest beta.
Would you mind giving me the name of the app that you are using to test the proximity sensor so I can tell you what I'm getting?

Proximity Sensor, Androsensor and proximity recalibrator (doesn't seem to work, which also leads me to believe it may be borked).
What happens in Proximity sensor is that when i cover it, it will report 0, then stay stuck there and says that it's covered. If I restart the app, it seems to reset.
This seems to work correctly for me. The app I am using is AndroSensor, it only shows 2 readings, 0.0 and 3.5 inches, which I assume would be equivalent to near and far. I noticed that if I quickly wave my finger across the sensor, sometimes it will change to 0 and not go back to 3.5. However, if I move my finger over the sensor, wait a half second, and remove my finger, it will always jump back to 3.5.

Yeah. The problem is, mine stays at 0.
May have to restore to factory settings and send to HTC...
Are you wanting the proximity sensor to work as it should, or are you simply wanting the screen to stay lit when on a call? If you just want it to stay lit, install an app called call light. I briefly had a HTC hero, which had no proximity sensor but the screen still went off during calls. That app allowed it to stay on.

I want it working properly. Screen off during calls, and back on when off.

[Q] Soft key backlight?

The lights for my three softkeys don't always turn on, unless i cover the front cam/light sensor with my finger. any way to fix this so that the backlight turns on when i'm using the phone?

its automatic with light sensor
yeah, i get that...
but, i'm sitting in complete darkness right now, and the soft key lights aren't coming on. the only way it does is if i cover the front camera with my finger.
does that mean it's faulty? or is there something i can do to make the lights come on when they're supposed to?
Mine are hit or miss. Most of the time I find myself covering the sensor like you said. Didn't see an option to adjust sensitivity or anything. Pretty lame.
I noticed this too. They should make settings option to be selected by user...miss the perfection of the NEXUS one

I think it is faulty, my key light is on whenever the surrounding light condition is poor. Don't think there is a setting for this but I might miss something here.
Bottom line, if you fully checked the setting cannot find anything, just exchange it.
Mine also seem to be inconsistent. Sometimes they come on immediately (like they should), sometimes I have to open an app, and sometimes they won't come on at all.
One wacky theory that I have is that the sensor is getting tricked by the reflection of the screen from my glasses. It may be in my head, but I feel like the issue comes up less when I am wearing contacts.
Maybe a solution
Have you tried this one? I did on my cm9-ed U8160, maybe it works on your devices too.
Mine are perfect, never have to cover the proximity sensor. Probably just a thing with different batches of devices. Got mine early summer around June.

Screen Turns Off While on Phone

Title says it all. Its a very odd glitch. If i call someone, unless i quickly exit the phone app, my screen turns black but my call will continue. I cant turn the screen back on until the call is ended and i have to pull the battery. It happens regardless of what rom im on. Any help? Thanks in advance everyone

Have your cleaned your sensor in the front of your phone.

No, what is/how do i do that?
Edit: I also have a ghost armor/ slick wrap sort of thing on the front of the phone. Is that the reason?

I would try removing that skin, it could be blocking the proximity sensor. I had the same problem on a galaxy nexus. I tried clearing phone app data, reboots, factory resets. In the end had to send it in on warranty because the sensor was bad.

Its weird though because the screen only turns off if the app i am running and xcan interact with is the phone application. If i use firefox or anything else while making the call everything is hunky dory.

Try using an app that shows sensor readings. I like to use Elixir2 which has a sensor section. When viewing the proximity sensor readings, it should indicate "Far" when nothing is activating the sensor, and "Near" if you cover the sensor (with your finger or whatever). If it reads Near without you purposely tripping the sensor, your protector could be covering it or something else is wrong.

Yeah try this. Problem with my phone was intermittent, clearing the phone app data seemed to fix it but it always came back.
Just out of curiosity did you ever install an app called facebook contacts?
Sent from my SCH-I535
Not an app besides messenger and the actual fb app persay, but i did sync them to my contacts
Sent from my SCH-I535 using Tapatalk 2
The app was actually facebook contact sync. It's a third party app and I had originally thought it may of had something to do with the problem. That's why I asked.
I don't think it's a software problem because you said it happens on all of the roms you've tried. My nexus was stock and I did several factory resets, even waited for the jellybean update. Nothing I did was ever a permanent fix.
So I think either something is blocking the sensor i.e. dirt or the screen protector, or the sensor is bad.

My proximity sensor went bad after I replaced a screen lens by heating up and unglue technique. I turned it off in the phone app, and now it's fine, but for me it's very irritating that I have a high-end device which is somewhat broken, so I started researching what's wrong and how to fix.
It does work, I tested it by enabling hidden menu ( *#22745927 ) and then diagnostic mode ( *#0*# ) + click "Sensors". It does show proximity sensor at ADC 16 or more (I think it triggers at 15, so always on). When I bring the hand to the sensor, ADC goes to 100, so the sensor is somewhat working, but it always does sense something which isn't there, which is causing it to misfire. I have another good S3, and ADC value on it is 0 or 1 when nothing is in front of it, so my sensor could clearly be better.
I have no idea what ADC is, by the way
I have another broken front panel laying around, so I took the phone apart and replaced a sensor with the one from that panel. I did see a slight improvement, which is: ADB value went down to 11-12, so the sensor was not ALWAYS in triggered state, but clearly still no bueno.
What I'm going to do now is get a new item and try replacing with a new one. It's not overly expensive, like 10 bucks when shipped from china (search for "Front Facing Camera s3" on ebay). Should that be a success, I will post my results here.
I also am not sure if it is possible to recalibrate sensor to not trigger if ADC value is, say, below 20 and such. I would imagine there could be a configurable value. Somewhere this value of 15 is coming from, isn't it? So, idk, if some guru here is reading this post, maybe could advise where to go to configure it
Not to keep this thread alive or anything, but I gave my dad my old phone and he complained to me a few days later that the screen kept going off as well so I met him only to find out that he had the case on wrong and it was blocking the proximity sensor. He definitely is not cut out for a smart phone.

UPDATE: I bought a brand new sensor/camera block, and same issue there: minimum ADB is ~12. So, it's glass. It is possible that the sensor openings are either slightly shifted, or too dark.
Anyone knows how to configure the threshold value?

Proximity Sensor intermittent

First time poster, though been a regular lurker.
It seems I have a slightly dodgy proximity sensor. Have checked with one of the proximity sensor apps and while the sensor detects if I have my hand over it, it is very unreliable when I take my hand off. It can take from anywhere from 1 to 30 seconds or sometimes never.
While ive been through other threads where people have a completely failed sensor, does anyone have this intermittent problem. Also is this a hardware or software issue.
Im currently htc-dev unlocked running Pacman v15.0.
Out there is a tool for recalibrating the sensor, but you would need to be S-OFF I think and it's done with a service tool (a special PG88DIAG.nbh)
Let me know if you are willing to try it, but it is VERY dangerous if you do the wrong things.
I had the exact problem from the very beginning. Got a phone and the very next day had a screen protector applied. For a few days proximity sensor created problems. The screen would go black when the call started, but until the call did not end, there was no way to bring the screen back. So, I used an app just like yourself to check and saw the same thing happening. Ultimately read extensively and realised it was due to screen protector. Took a scissor and cut off the protector above the sensor. A few months later when I had a new protector (of a different company) applied the same problem reappeared, so I had to cut it off from the top. Except that this time around I was sort of expecting it. I hope this help! :fingers-crossed:
I had the same problem and it continued no matter whether i remove the protector or cut the portion....im unable to most awesome ROM's.......only n sense 4.0 im able to re turn on the screen using power button.if there a way to completely disable this turn off during calls irrespective of the ROM its highly appreciated......
Looking forward for the solution

An update to my situation.. I ordered a new proximity sensor on e-bay and have replaced the same on my phone now. While I was at it, I cleaned up the window as it was pretty grimy and could have been the source of trouble. Also cleaned up the contacts with Isopropyl alcohol. End result.. Im still having the same problem!!
Im pretty sure now that its not a hardware problem and has to do with the calibration. What I have noticed that the sensor works fine in bright sunlight but not when there is less light around. Also am not using a screen guard!
Would it be possible to guide me to the right tools to recalibrate please?
Sorry, I haven't done this myself, but I'll search a bit how it's done by HTC.
They are using a special holding station where the devices are calibrated.

Proximity sensor doesn't work during phone calls

My screen goes black when I am in a phone call and it does not turn on unless I hold the power button or something like that. I have already went to the proximity settings to test that it is working.
Any ideas?
Firmware version? Seems to be a bug in last firmwares. Also had this issue some time. Now it seems to be gone.

.In the process of backing up my phone atm to try a factory reset. I'm on latest T-mobile version though.
How did you fix yours?
Bump. Anyone? Is there a fix or is my sensor faulty? Because if it is I can still send it back in for a replacement. Sometimes it will work fine, and sometimes it won't.
I've got similar problem. When sensor is activated, it's keeping activated even if nothing is in front of sensor, so I have to wait for other side to end a call.. any suggestions?
EDIT: problem solved-> I just cleaned the glass on proximity sensor, maybe some dust was there

I also have a problem with phone's proximity sensor. With me, it shows some signs of work right after i boot up the phone. In service menu (*#*#7378423#*#*) -> Proximity switch starts with On value and then goes Off, On, Off, On.. a cycle of at least one minute. The interesting thing is when i cover the sensor it stays On, which means it detects its working. I suppose the sensor is faulty, as I tried several suggested methods to resolve this issue: pressing firmly on top of the sensor, factory resets, reinstalling the software with Sony's PC software kit, some applications from Google market, etc. None of them helped.
As I bought my phone 2nd hand, I see the upper speaker is pressed on its left side a little bit, as if the phone was dropped exactly on this spot at the speaker (which I find is almost impossible, as the front panel is perfect without scratches or anything) or somehow it was pushed with some sharp object. I explained this as it might have a link with the proximity sensor issue, or it may not be connected to it, not sure.
