[Q] Dresire S - Proximity Sensor Problem

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.

Top left of the screen in opposite place to led, if you tily screen under light you should see the sensor reflect back at you

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

How can I disable my proximity sensor?

So I dropped my nexus 5 and the top part of the screen cracked so that the proximity sensor either no longer works or a crack is now covering it (I think its the latter) so that when I'm in a call the screen will black out as if I'm holding it up to my face no matter what even if I tap the power button. Is there anyway to disable it so that the screen is always on during calls? Im on android 4.4.4 and so far I haven't found any solutions yet other than maybe rooting my phone and disabling the hardware itself. Any other solutions?

I don't think it is possible without root, but why don't you root your nexus? it's easy enough and will fix your problem

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.

Mother managed to break proximity sensor

My mom managed to crack her screen and hence break the proximity sensor and when it's in a call (did tests to verify it is broken), the screen doesn't turn on at all. Is there a way to turn the screen on during call feature off without rooting? At least some kind of temp fix until we have time to get it replaced? Everything else in the phone works great. It's running stock.

Anyone else having this problem?

When I try to pull down the notification bar on the right the screen goes black. Also turns off the always on display. I'm assuming it's something with the Proximity sensor. Tired of all the little bugs and problems with this phone. I’m returning it. Just curious if anybody else is having this problem.

No, mine isn't doing that. You might have a dud.

I've had that happen on my Pixel 2 XL. Only once or twice and restart fixed it every time.

It's definitely the prox sensor. Always On Display shuts off when the phone is in your pocket or face down, which is detected by the proximity sensor, so that's totally normal. As far as it happening on the home screen, it seems like the phone thinks you're in a call, which would use the proximity sensor to turn the screen off near your head. I would reboot as @jimv1983 suggested and see if that works.
Are you using a screen protector? Sometimes those can cause issues with the proximity sensor, but usually it just causes the screen to shut off and not come back on during a call as it senses the protector at all times instead of your face.

I had a case with a built-in screen protector on it and I thought that might be what was causing it but after taking it off it still did it. Weird thing though once I put it on the wireless charger it stop doing it. Hasn’t done it all day even with case on. Weird. Still thinking about taking it back to Best Buy and swapping it out.

I've had a similar issue where the proximity sensor will not deactivate as long as a call is going (can't hangup, can't unlock, can't speaker phone, can't mute, etc.). I have to wait for the other person to hang up. Get an automated robo-call you accidentally answered....oh well, guess you have to listen to them. I have never been so angry at a phone as I am with this one. Especially as expensive as it is. I absolutely would NOT have bought this phone if I knew ahead of time how aggravating this would be! Thinking of sending it back. BUYERS BEWARE!

Had this very issue with my pixel XL and blowing on the top speaker grille of dust with compressed air solved it.
But if this is out of the box that sucks. It should not be like that. My pixel was approaching two years when that happened.
