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
Hello everyone,
I've the following problem:
When i call someone and the telephone is in a horizontal position the sensor isn't working correctly. When i put my finger on it the display doesn't turn off. If i hold the phone in a vertical position everything works like it should.
Can someone confirm this?
Sorry for my bad english.
Thanks in advance!!

Because nobody could help me and answer my question, I try to explain it better.
It would be very nice if some people could test the following steps:
1. Put the telephone on a desk/table
2. Call a number for example your mailbox
3. Put your finger over the proximity sensor
-> Is your Display turning off or is it staying on ?
This is what i want to know and I thank you for few seconds doing this test
For what it may or may not be worth, covering the sensor with my finger does nothing, but my screen does actually turn off when I've got the phone to my ear.
...and here's the trick: if the phone is held vertically, covering the sensor with my finger works!
Yeah when the phone is vertically - no probs, too.
But try to make a call when you lie in bed
That won't work, but wtf samsung?
In Eclair the sensor works perfect. and it doesn't matter if the telephone is held vertically or horizontally !
With the Skype telephone app, there's no problem.
So i think the Phone.apk is the problem for that.
Is this possible to fix? I can't do this because i am a noob ;-)
But maybe others ?
The sensor is responsible for the Palm Motion (screenshot capture with hand gesture in front of the sensor) and the "Mute/pause" by covering the sensor, doesn't work for me ... I guess it's sensor problem, but It could be also software problem...
Anyway I'm on S4 I9500 (what they call Octa core) I'm rooted (Cofface root) and my Android version is in attached image.
I'll be happy if you guys can check if it works in your device... just go to:
Settings> My device> motion and gestures, then turn on the "PALM MOTION" toggle...
And if you make a gesture above the screen from right to left or left to right and the device does not take a screenshot, you probably also have this problem ...
I'd be happy if you comment here and update us.
By the way - what is Samsung's secret dial-up codes to check the sensors?
Thank you!
By the way, I found some schematics for the I9500 and I see that the left sensor is a light sensor and not proximity/gesture sensor... but anyway, I've activated all Motion and gestures toggles, but Palm motion still doesn't work!
Quick glance does work perfectly and also other Gestures and auto brightness, so I don't understand why the palm motion doesn't work if it uses the same sensors?

Any ideas?
Just so you know, I had a lot of trouble figuring out how to take a screenshot the "gesture" way and, unlike on the SGS3, it seems the side of your palm needs to be physically touching the screen as you swipe from left to right. At least it does for me!
Hi, 10x for your reply...
I tried all variations, but no luck... :\
And Palm mute/pause doesn't work too...

Palm mute/pause doesn't work for me either. Hardly any of the gesture's work well enough to be useful
hhmmm... this is so weird... I tried it on my friend's S4 and everything works great!
I think this is a software problem, I think I'm gonna download the latest Firmware and flush it via odin and check it again on stock version! maybe something messed up when I rooted my phone, or my stock firmware is not the latest one? (chek my attached image) does your device runs the exact same firmware as mine dose?
10x.:good:
Update!:good:
Ok I think I found the problem, for those who have that same problem, relax, probably the hardware is fine, As I assumed, this is a software problem (specific Build I guess) I dialed #*#0* in the Dialer Aoo and it's launched the device sensors debugger... and there you guys can check if the sensors are fine!
I suggest to check these particular sensors:
1. light sensor
2. proximity sensor
3. gesture sensor > Direction
and there you can verify if it's a software issue or hardware issue...
hope this helps somebody.
cheers!

That number doesn't work for me
Ooops...
My mistake, the right number is: *#0*# (star hashtag 0 star hashtag )
good luck !
Your hand has to physically touch the screen. Then both screen shot and mute work

Meltus is right. Your palm needs to cover the screen physically in order to work. As for the screen shot, the palm needs to physically swipe the screen

Hi
My finger print scanner seems to only work about 10% of the time, anyone else had this problem and how do i fix it?

No problem here, way better than the sensor on the Note5. Have you used one before? I wonder if your fingers just don't work well with them.

Go to setting, security, imprint and setup another finger, you can use the same finger if you like. Make sure if you are using a case on the phone that you setup the imprint with the case on. If you setup the imprint with no case, then put a case on your phone, your phone will read your finger differently, therefore it may not work correctly. You scanner should read your finger 9/10 times if not more
if it works that bad, delete all prints and RE DO
mine has yet to fail
i have set up my finger again, the problem im having is that i can access my phone by the power button thus by passing the finger scanner most times. Surely i should only be able to access my phone when my finger print is confirmed.?
You should just be able to use the finger print scanner and not touch the on button at all. About 99% accurate for me.
When you set it up, did you keep moving your finger on the sensor between presses (not during) to make sure it had a good cross section of the finger to recognse?
All is working fine now after the recent security update from google
Hi,
I need to know something. I hope you'd help me.
On the g4 plus, how fingerprint scanning is working? the sensor is excited for finger's sense at all times or only when the phone's held in the hand ie when the phone detects a motion? Asking this 'cause I'm having some weird problem. My sensor doesn't sense my finger at all when I don't hold it in my hand. I just put a finger on the sensor when phone's absolutely still on the ground in sleep mode, not moving. But the sensor was unable to respond. I have to press it harder to make it detect my fingers. Quite irritating.
But the sensor properly detects and senses my fingers when the phone's in my hand. What could be the problem? Is the sensor defective or it's perfectly normal ?
It doesn't work when is horizontal on a table. If you press slightly harder, the phone moves (tilts "up" the top part a little) and it works.
Weird for me to test since I have registered only my thumbs. I never use it like that. On table I see the notifications and if I need to do something about them, I always lift the phone up from the table.
Mine (UK model) works just the same on the desk or in the hand. no added pressure required. maybe try re-doing the finger registration
Are you sure that the phone's in sleep mode when you touch the sensor? Just put the phone on table for 2-3 minutes and then try to touch the sensor without touching anything other than it. Could you please check it again... Can you unlock the phone?

In that case, my replacement for the phone isn't unnecessary.
What I feel like when we move the phone a little then it activate s the FPS and it works fine.
But if the phone is stationary for some time and touching the FPS doesn't unlock.
So I think it's not a problem.
Mine works fine also... but I can't use the finger print sensor to sign in apps or remember passwords on the browser (I use chrome) ... I used to have a Galaxy S6 and it automaticaly asked me If I'd like to use the sensor for this ... but G4 don't.. can anybody help me with that? thanks
