Phone display keeps coming on during calls

Has anyone noticed their phone likes to turn itself on during phone calls as the phone touches your head?
I thought that could be fixed with Advanced Configuration Tool and these options:
◦Phone sleep during call
◦Fast sleep during call
But they both are gone. They were there on my Kaiser. Any ideas?

It's supposed to turn off due to the proximity sensor. I'm using a T-Mobile USA TP2 and it turns off as it touches my ear. One way you can test this, if you haven't already, is to call a phone, then as it is in progress, lay the phone with the screen up, and put your finger across the top of the facade of the phone (cover the top area where the earpiece is). When I do that, in order to replicate my ear towards the phone, the proximity sensor blanks the screen.
As for the AC tool settings you mentioned, I've never touched those, so mine are on the default settings.

Hey, wow! You're right! When the device is against my ear, the display is out. As soon as I pull it away, even slightly, it turns it on!
I'm simple, I know. My wife tells me that all the time.

It's okay, when I first got my TP2, I encountered the same thing you thought was a problem. Then I saw a video online demonstrating proximity sensors and the guy on the video put his finger along the top/speaker area of the device and the screen turned off. I replicated his actions on my TP2 and realized that the proximity sensor activates when something is touching it or gets fairly close to it. BTW, we're all simple; we just excel in different ways!

LOL, me and the wife learning this stuff too. Hey, heres another (which i just created a post for), GO rub a magnet on the face of the phone while the screen is OFF, right over the tiny keypad. If you have a soft case with magnet in the flat, go see the funky result

Well since I'm already here and I don't want to search for that post (sorry to the Mods since this is irrelevant for this thread), I can answer that too. It's already a well-known issue. The magnet tricks the phone into thinking either the keyboard and/or the stylus is being opened/taken out. However, it is more accepted that the phone is being tricked into the keyboard being opened. There's a registry edit posted on these forums that can fix that, but the downside is if you want the screen to turn on when the keyboard opens, it will no longer turn on without having to press the screen wake-up button.
I'm just using the Slide2Unlock v.204 for WVGA devices. It keeps the phone locked even if the screen turns on. When I slide my phone into my magnet-clasped holster, it sometimes turns on. It's just a habit for me now to check the screen once it's in the holster, so I can turn the screen off if it woke up by itself.

Proximity Sensor

Hey i don't know if this deserves its own thread or not, but i think it'd be pretty cool if the proximity sensor on the Touch Pro 2 could be used like those on blackberries, that when you put the phone in your pocket or a case with the screen on the screen would automatically turn off then turn back on when you took it out. Don't know if this would be possible but it is a really cool concept. Thanks

blackberries turn on cause theres a little magnet in the cases that turn on and off the screen. i dont think any blackberries have a proximity sensor. the storm is the only one with a touch screen to accidentally hit but you have to click it to do anything, and if your pushing a bb hard enough into your face to make the screen click, you deserve the have it push random buttons.

oh ok, that kinda sucks, still be kinda cool if it could be done though

i was wondering if theres some way to change the sensitivity or distance of the proximity sensor, i notice when my wife was using the phone the screen would turn on and off randomly i guess because of the way she was holding it to her ear, then i started noticing through the corner of my eye that my phone was doing this as well, it must think i've pulled it away from my ear when it senses different cavities in my ear, i'd like to turn it up to an extra 1/2" or so when i do hold the phone to my ear i know for certain it stays off, and when i really do pull it away from my head the screen wakes up. has anyone found the settings for this yet? i'm running juicy rom and my wife has mightyrom

you could have it that way but you would need to disable the power off after x minutes. then all you would need to do is keep the proximity sensor enabled

Changescreen has an option under the advanced settings to suspend the phone when it's placed face down or in your pocket (as long as its put in your pocket upside down). It doesn't turn back on when you pick it up or take it out of your pocket though, you have to hit the suspend button for that. I'd reccomend checking it out.
Oh ya it also does screen rotation via the G-sensor.

I'm not sure if Changescreen actually uses the proximity sensor. It will shut off the screen even if you turn it upside down in the air. And I have found on numerous occasions that it still leaves the screen on in your pocket, which is too bad because it's handy to have.

Try PocketShield. It will automatically shut the screen off when put in your pocket or case. There is a free and paid version.

I'm with t0mmyr on this issue.
I too find that when having been on a call, my screen can end up with started apps, on the programs page, etc.
I too think that a 'tweak' on the proximity sensor will go a long way to fixing this issue. The trick is to find exactly what to tweak and this is where we need a little guru-like guidence.......!!!

theres a few interesting keys in hklm\software\htc\proximity. i wont mess with them. i wouldnt like the screen to turn on every time i pick my phone off a table or something.

Thx for the heads-up
I looked into them but with no result.
There must surely be a way to 'fiddle' with the range..?
Cheers
Jabberoo

i dont think there is a boost on range. i think the emitter intensity is fixed and would require hardware tinkering to make reflections on object brighter for the receiving sensor.

Actually I played with it a little and realized that it does in fact use the proximty sensor and g sensor. It just seems to bug up some times (or it just might be my device)

Not just yours mine does this as well. I make sure I don't move the phone away from my ear at all but if it is a long call it always seems that either the notification bar or the start button got pressed during the call. It is driving me nuts. I had a program written by someone on XDA for my Fuze that worked awesome called touch in-call screen tweak I want that functionality with the tilt 2

TouchLockPro has InCallTweak built in. See youtube video in the link. And recently also has added ZoomBar unlock. And it is *FREE*

Face Recognition App

Do you think someone will make an app that will detect your face and unlock the phone now that we have a front facing camera. Also what is the motion sensor used for?

That'd be awesome

Sweet. Hopefully it's hacked with front camera access and the ability to enable it by holding the volume rocker to do the scan. Hopefully you don't wake up one day looking really ugly.

Lots to hope for LOL
It would be nice to have the camera key on the side though. There already a couple of face "detection" apps out there, not recognition though. Photofunia, in market, takes face and puts in various backrounds, works well

One example of the motion sensor is that when someone calls you, the Evo quiets the ringtone when it detects you've moved your phone with the intent to pick up the call.

It's actually a proximity sensor, used to turn the screen off when it's held close to your face. The feature of the ringer quieting on pickup uses the accelerometer.

So what does the motion sensor do?

I think he means "accelerometer" when he says "motion sensor"

The Light sensor via front of HD2 disables touchscreen of device when held close to face! The motion sensor is used for screen rotate and other apps that work well with phone positioning commands!

The light sensor has nothing to do with disabling the touch screen. Its used to change the auto brightness of the display. The screen shuts off when on the phone because its turned upright.
Well that's how it works on the evo. So I would think the same for hd2 that u mentioned in a evo thread...

It is turned off via proximity sensor not accelerometer

Ahh, but u can hold the phone next to u and the screen won't come on till u tilt the phone horizontal...anyway its not the light sensor...And yes a face recog app would be very cool to have...

People, people! Please!
1) Accelerometer: Used to detect changes in movement. Used primarily in Android for apps such as Bump, or to rotate the screen, or games such as Teeter and racing simulators (tilt phone like you're turning the steering wheel, etc.) Also known as the motion sensor.
2) Light sensor: Used to detect ambient light so that when the phone's brightness is set to automatic, it knows to increase or decrease the brightness of the screen appropriately.
3) Proximity sensor: Used to detect if something is near the speaker and of the phone. Mainly it is used to turn off the screen and touch input when it detects something near its front, and a call is in progress (aka, detects the side of your head near it, so your cheek doesn't accidentally push any buttons).
As for the facial recognition, yes, that would be nice, but what happens when you get a haircut? Put on glasses? Have a zit? Get a black eye? Swollen lip? Sunburn? Grow/shave a beard/mustache/etc.? That's the problem with these kinds of software, and why all computers that have facial recognition will always have a password or some other kind of backup authentication.
Questions?

no... asus laptops have the face recognition systems and it works GReAT!!! no problems whatsoever... but thats b/c u can put sooo many pictures and set the sensitivity of the security on the camera... its pretty sweet

It's also a laptop and you still have the password login as a backup. Believe me, I used to cell them and had to reset the password every other day because bratty little kids came in and thought they were smart and tough by setting the camera login to themselves making some disgusting face, and the password to "toughguy" or "password".

Wow!!!!!!
is this app out yet? Couldnt find it on the market..

*This was posted from my Evo 4G using Tapatalkpro! Great app, if you want to browse and post through many dfferent forums*

Would be pretty great!
Lol at the misinformation, thanks for clearing that up for our slower folk.
This is definitely gonna happen sooner or later.
It would need a backup method of course but if made properly it would be more general and little things wouldn't change the outcome.
I was thinking this...
You take 3 pictures the first time you open the app.
It merges them, aligns the face and sets a gaussian blur to smooth and remove imperfections.
Then it cuts out things like hair and eyebrows leaving behind the static parts of your face such as eye shape, nose, mouth, jawline and cheekbones.
It basically takes the 3 specific pictures of your face, and generalizes them, while keeping them relatable to every future pic.
I think its called interpolation, which gives you the perfect identifier, ultimately being used to recognize you.
Of course a setting would be needed to change how similar the face needs to be before being granted access but theres no reason it wouldn't work.
My other going thought is an app that learns as you go but it won't work as well.

nope again!

iTS AN OK thought of how it works but my HD2 can be of any position even flat down and as long as I am in a call and i put my finger over the light sensor (same as face, ear being close to sensor not letting hardly any light get to it)
the screen disables! I think many of you may not have the HD2 if ya didn't know that, don't let internet chat and gossip get in the way of the truth, truth is within the device when holding it, not hear-say. Also why would the accelerometer have anything to do with disabling screen when in an upright position? If one was to lay down in bed chatting on fone, my HD2 would un-disable screen... Try an app called mToolbox, it emulates what light sensor and motion sensor can be used for. I would say, light sensor can be more useful in many more apps than motion, motion works great with changing screen from portrait to landscape and movement in games.. An app to control ps3 via bluetooth using HD2's accelerometer feature would be useful, but for now, i have tweaked it to off, I have many older WinMo's and find using the screen orientation key much more faster and when i need it, it gets annoying when the screen changes at unwanted times and no matter how you calibrate any accelerometer, there are flaws to it depending on what situation one is in when holding the device (fone must be upright again to go back to portrait if fone was laying down) sorry for the long babble but I'm certain that the light sensor own's the screen shut-off feature on the HD2 for sure.. Quote me again any time!

Proximity Sensor Adjustment

I was having trouble with my face turning speakerphone on or hanging up the call.
Turns out the Rezound proximity sensor adjustment app works on the HTC One as well. Made the sensor turn the screen off from further away and all problems solved.

Did you try my settings? Is the app showing the NEAR/FAR toggle change from farther away? The only way I see you holding it wrong is if the sensor is looking past your head completely. Sensor is in the top left corner of the phone.

I've always had the problem where when I'm done with a call and pull the phone away from my face, the screen doesn't come back on. Happens 99% of the time.

Screen off during call

Just a noob question, does our zl's screen does not turn off during call specifically when you put your phone near the ear? Mine's not turning off.

The answer is your proximity sensor has been disabled , so you must try uninstall the 3rd app what made it disable

i had the same problem, but it was not always (sometimes).
After the full hard reset it become very better, but not ideal.
Sometimes i feel that my ear pushing the numbers while talking )))) maybe it global problem of model?
