light sensor app like Iphone (incall screen off)

I was wondering if there's a app that allows the screen to turn off when you put the phone to you head? Then when you bring it out and in front of you, it turns back on. My Iphone did that and I loved that feature.

upping cause i'm intersted too

im believe this feature on the iphone is provided by a proximity sensor, you can probable do this with the light sensor but it would only work in the day time bc at night the screen would always be off...

not unless you use the gsensor too? i think if you work with the light sensor and the gsensor..you can get it to work. maybe have it only work when theres a active call.

This is an extremely good idea!

now if I was only a programmer

i'd love to see this feature on my diamond/blackstone too, i always have problems with the cursor jumping somewhere else when taking a note while in call...
theres already a thread about that:
http://forum.xda-developers.com/showthread.php?t=451456

sweet. thanks

I really love that fuction on iPhone as well. I found some program that can adjust the Light Sensor to dim the back light as you want. I never try it but surely not work in the dark. If any news on this issue, pls advise!!

I think the g-sensor is the answer, off course in combination with light sensor. If someone could make an app that would turn off the backlight during an active call AND when phone is in vertical position; this could resolve difficulties with light sensor.

There are a couple out there that attempt to solve the same problem the iPhone does.
One I know of is Touchlock Pro - http://forum.xda-developers.com/showthread.php?t=444215
It is free but it still has a little way to go before it is a polished solution
The other is PocketShield -- http://www.pocketshield.net/
It's not free but I found it so effective for the in-call problem as well as general locking/unlocking that it was worth paying for
I've also, as a developer by trade, played with the light sensor, g-sensor, and stylus sensor APIs and tried to create a basic proof of concept that solved just the in-call problem very well and found that without the approach taken by Pocketshield it just was not reliable enough for me.

All these programms are great software but are nowhere near the iphone solution... like i already said, the problem is e.g. that if you are on the phone and the person on the other end tells you a phonenumber you need to write down - the cursor always jumps to somewhere else as soon as you put your phone back to your ear (and then take it away again ofcourse to continue to notice the number).

ive messed with those apps before with no luch for what i was looking for. Simple app...JUST for incall and end call. light goesout..then comes back in. those other apps are pretty detaild

Very true, but unfortunately this hardware does not have the same sensor as the iPhone so you can only fake it so much.

I'd love to see this developed as well. But just wondering as some have mentioned using the gsensor; what if your laying down using the phone?

any developers out there. this would be awsome. make it simple. only works when the phone is in call. the gsensor sensing the phone from 0-45 degrees and only 0-5% light. seems sorta simple when u look at it like that.

hey everyone. My HTC Touch Pro came with this functionality out of the box. And i really don't like it at all. I think the difference to the iphone is that the screen does not turn back on until the power button is pressed.

My diamond does this already?

mine didnt. very weird.

For what it's worth, S2U2 v.1.42 has an option called "blank screen on call" which essentially disables the touch screen and makes it turn off when a call is connected (both sent and received). To get the screen to turn back on, simply press any hardware button. (Note though that pressing the END button while on a call will end the call as well as turning on the screen.)
I've found this feature to be VERY useful and figured it's as close as we're going to get for the time being .

G-off Display

"Description:
With G-off display you can turn off the screen by rotating and holding the phone upside down and holding it like that for a second.
To save battery while listen to your favorite music, simply point your phone downward, light off. All background processes remain.
Require G-sensor found in the latest HTC devices like Diamond / Pro / HD, etc."
Download

Just what I need! but...
Hi
This is a nice app that i've wanted. I know I could use Changescreen as it has a similar feature, but a standalone like this is more preferable for me...
But I just can't download from Rapidshare...
Is it possible to load the .cab here since its only 345kb? or a mirror to somewhere else...
Anyways, Thanks for pointing this App out...

Works like a Charm!!!!

Installed on my TP doesnt seem to work and no progam icon to make any type of changes?

great idea. tried on my Omnia, works fine. but screen powers on only with Power button

installed on my touch pro, but doesnt seem to do anything any ideas, would really like to have it working am on WM6.5 if that makes any difference...
cheers!

Installed on my Diamond
it's ok

After a call is not working so
only works after soft reset.
Anyone same problem? solution?

Same problem here. I have to kill it with task manager and run it again It's faster then softreset...

Hello
how about battery drain pls?

not working on HTC Rhodium (TP2) - also I can't see it in programs, etc. Do I need to do anything else after install?
I got a question are there any options? like on conference call (when using loud speakers - device is upside down), will it ignore the g-off? Because I am not sure what would happend if I would press POWER BUTTON in the middle of the call just to get the screen back ..

Not working in my Touch Pro, too
Using latest WinMobile 6.5.21935.
I also did a softreset after installation!

You don't see it. But it is there. Go to the Program Files and the directory with the same name. Click once on it, and tune the device upside down. It will switch it off.Not ON again.
You can link to it.

origin of g-off display
Beware! I am NOT the programmer. I don't know who is either. I just found it.
btw ChangeScreen has a "display off" option too.

worked on the tilt 2
it needs dot net compact framework 3.5 and then it loads on startup... closing the title bar that comes up doesn't seem to stop it from working. however, having said this, i can't say that perhaps the tilt 2 didn't have the behavior before i installed this... it took me a while to realize that upside down doesn't mean face down, which is what i had wanted. but having said that, turning it upside down works great because you can put it in your pocket upside down (which basically you might do anyway).
also, indeed, to get it back on, one has to push the power button. but that's good in case the device moves out of tolerance for downward position it won't be going on and off unintentionally--except that even after the screen is already off it will keep executing--i know this because it vibrates when the screen goes off as well, and if i take it out of upside down position and then put it back without turning screen on again, it will vibrate again. this said, walking with it in a pocket didn't seem to keep triggering it, so overall this is a really cool hack.
now for figuring out why my t2 doesn't turn its speakerphone on when placed face down during a call (i was thinking face down should always turn the screen off by way of proximity sensor--which does work on my device because during a call holding finger over ear speaker turns off the display--just doesn't turn speaker on). wait... just realized... if it did then it would have to assume that just putting it to the ear should turn on speaker. so, i'd say what we have here is a challenge... integrate the proximity sensing with the g-sensor to always turn off the display when face down on a flat, reasonably level surface-- and during a call turn on the speaker too.
if this can be done, then combined with the g-off existing functionality it'd be really sweet--i wouldn't have to turn it upside down _before_ placing it flat on a table while listening to music. and the proximity could help make it less worrysome to just automatically turn the screen back on when picked up.

sorry for the duplicate post above--tried to edit, then hit save by accident
edit... i just tried screenchange and it in theory seems to do exactly what i want, but in practice, with 2.78 and any sensitivity level and appropriate no light option checked, it turns off the display even if there is light (and lots of it to be sure). i hold the device upside down above my head and the display goes off. i'm not covering the proximity sensor. my proximity sensor does work when in a phone call. i tried rebooting. i think the proximity sensor may be off somehow on my device...maybe htc only wants it on in a phone call? i will have to see if screenchange will work right with the device in a phone call... further posts will go over with screenchange.
btw, regarding the forum... its annoying that my edit made a whole new post in the first place.

cool！！！thanks

proximity sensor speed on Leo?

Just wondering, how fast does the proximity sensor react? Does it turn on also when u move it away from ur ear?
In my HD, its pretty slow, and if i remember correctly i even had to install an aditional cab to make it turn back on.. I remember using an iphone and the second i took it away from my ear, before i had a chance to have the device in eye sight, the screen was on already..
how is this with the leo?

Your HD doesnt have a proximity sensor, it uses a light sensor? I think.
The HD2 one is PERFECT! put the to you ear, screens off instantly, take it away and the screen comes back on.

I would echo the fact that the sensor is perfect on the HD2. In fact, I think it's even a little better than 'instant'. For example, if I switch ears quickly, the screen doesn't turn on (exactly what I want), but if I take the phone away from my ear, by the time I've focused my eyes on the screen, it's on and ready for input. Works like a charm!

I'm not sure I'd say it's perfect. For instance, mine doesn't seem to work in the dark (i.e. in a dark room, outside at night, etc.) which is exactly the time I'd like it to work the most.

good to know that!
on the HD i have to wait a good 1-2 seconds for it to turn on, and its annoying what ur ready to go and input something, but u actually are waiting for the screen to turn on..
closer to the Leo..

My (old!) HD is slow too and I gave up trying to use the screen blanking because it also turned off and stopped me from entering key presses to access menu items in the call systems - even when away from my face.
My HD2 is faultless . Works exactly as designed as far as I can see and I have had many phones. If you are considering the HD2 then I would have no hesitation in recommending it.

im not evaluating, it was just out of curiosity, the only thing stopping me from getting the HD2 since day 1 is my current economical status .. im a phone lover also but its still good to know what its improved since the HD.

Screen not going off in a call!!!

Hy all
I have a strange problem with my X10! The will not go off in a call! (or at least most of the times it won't) The sensors should turn the screen off while the phone is to to my ear but most of the time it will not!
There is a hidden menu that have tests for almost every hardware component but the test for the proximity sensor only shows that the sensor is OFF and won't do the test!
Ideas?

The sensor is the little black circle (sort of) above and to the left of the "n"
e.g. Sony Ericsso'n'
Have you tried putting your finger over it during the test?

same problem here i tried the finger-trick doesnt work

I tried it and the test shows ON while my finger is there! So the sensor works properly but why the dialer is not using it to control the screen?

As stated before, if you cover the 'hole', the screen would not react to any of your finger touches. The screen would still be on but would turn off according to your settings (like 30 seconds or 1 minute or whichever). Try it. Call someone, cover the hole and try to hit 'end call' or slide up the keypad and then cover the hole and try to hit numbers.

The purpose of the proximity sensor is to turn the screen off in a call while the phone is to your ear! if i cover the sensor it must turn the screen off! but it doesn't! There is some kind of timeout set to this! The screen will turn off but after some time! this makes the proximity sensor almost useless!

No, it is to disable touchscreen buttons. It will turn off when time you've selected is over and turn on again and enable touch buttons when you take the phone out from your face.
Though i think you're right, it should turn the screen off to save battery, it is silly to have the screen on when you are using it.

Quite right!
I guess the expectations are again set by Apple's standards. Their proximity sensor functions as one would expect.
However the sensor on the X10 does what it was designed to do, and that's to deactivate the touchpad whilst the device is held up to your ear.
The screen timeout is a different setting all together (unfortunately).

Not the expectation set by Apple. It's expectation for any right minded individual.
SE software is just well known as one of the worst top players in the industry.
FFS, they spent all the time on DRM, lock the phone, developing battery hungry useless software on 1.6 rather than push out 2.1 asap, that tells you something.

Why not go through the Manual once before abusing Company left - right.....
Let me copy and paste it for you guys........
Sensors
Your phone has two built-in sensors – a light sensor and a proximity sensor. The light sensor is used for automatic LCD backlight control. The proximity sensor turns the touch screen off when your face touches the screen. This prevents you from unintentionally activating phone functions when you are engaged in a call.

Yes and this is plain stupid use of the sensor! Take the HD2 for instance! Its proximity sensor turns the screen off the second you take the phone to your ear! This is done with every HTC device having the sensor! It is just misused on the X10! I hope that somebody here would correct this with a little program some day!

This is the main problem with us ,,, we start to compare and complain rather than think why did SE will give two sensors instead of one.
Answer is not known to me but this much I know they know better than us.
If you think you know better, be my guest and throw some knowledge here. I am new to Android but not to SE.

So im new to the forums, but I was having a problem with the proximity sensor...
As stated in a lot of threads, the proximity sensor does work and will "lock" the screen so that once your face is near the screen it will not allow any clicking of the buttons.
Also the screen is supposed to turn off about 15sec into the call. Mine turned off, but then all of a sudden turned on again...this would happen repeatedly.
I found out the solution...it seems advance task killer was not allowing the screen to turn off.
I had auto kill enabled and set it to when the phone was locked to kill apps.
I turned off auto kill, and everything seems to be working fine with the screen and proximity sensor now..
hope this helps anyone having this issue!

thx, same problem here !!

so its pretty clear none of us know the answer to this, but yet we're still bashing each other. LOL! ppl let's get constructive, we dont have the answers so lets accept the fact and seek help some where else.

o2 Germany told me, that Sony Ericsson will bring us an update within the next 4 weeks to all devices.
It will be an update with alot of bug fixes (e.g. proximity sensor ) and speed improvements.
So, be cool. Sony Ericsson is working on that and with Eclair in autumn, our battery will perform very well.

Unintended taps during call: how to prevent them?

Hi!
I"m not the only having the problem: during a call unintended taps takes place while screen waking up is not registered during the call. So, you see, I'm not sure a proximity sensor is the reason of the problem as far as screen is kept turned off.
I have tried to reproduce the issue by fingers, but wasn't lucky.
Have you any ideas how to eliminate the problem?
I mean not-rooted official up-to-date stock firmware use case.
And, by the way, I haven't found proximity sensor calibration in service menu for A1. Is it placed somewhere into another place?

That happens to me all the time too.

Yup, me too. While in call I sometimes unknowingly turn on the flashlight and probably look like an idiot. ?

With the rn3p I would constantly end up muted. With mi a1 the problem is much less although I've noticed that numbers are still pressed. I've learned over time to switch to keypad so when something gets touched it's not the mute and at worst the other person receives some key tones.

I also have this problem a lot. I mute myself 9/10. To bypass to problem, I just lock the screen before placing it against my ear.

Yes, a simple soutions is just when you call someone, imidiately press power button to lock the screen (no password or fingerprint requred to unlock)

That's what I've been doing. That and pushing the top part of the mobile on my face just to make sure. lol
Oh and use the Feedback app and send it to xiaomi and hope they fix it on the next update.

i had this problem too, has it been fixed in the latest of updates? its a really annoying bug.

You must be doing something wrong. This issue "must" have been in all smartphone operating systems in the world, if what you are saying is the truth.
There's no way to drop the call, or press anything while you are calling someone. The proximity sensor doesn't allow turning on the screen when it's close to an object. The gyroscope also turns off the screen when you rotate the phone vertically during a call.
But all I can say is that it's not a bug, this is how is your phone knows when you are in a call, and you put your phone to your ear, or when you use your "speaker", and so the phone knows it's supposed to used it's speaker to transfer voice through the call.
Beside my poor English, try to move your phone a bit vertically before putting it close to your ear.

same problem here, also disabling ambient display... i also tested proximity sensor with some apps and it seems ok

I have that problem too from the beginning. None of the updates came up with a solution

Same here: I mute, turn on the flashlight or even open apps sometimes with my face. And thanks for the input @SmallTarzan but i know how to operate a smartphone and did not have any similar problems for the last five years. Apart from that annoying bug it's a great phone.

Wow, i dont know of this bug since i'm using custom rom from very beginning.
Try to make a call then use your hand to cover top part of the phone, screen doesn't lock??

I am having this issue too and it is really annoying

And still nobody came up with a solution???
It's easy to understand why it happens.
Proximity activates while you're in a call, but apparently the touchscreen digitizer remains working (even though the screen is off). Touching the digitizer with your ears or cheeks activates different actions while you think your screen is locked.
I can't believe how this issue is not fixed yet! That's a shame!
Same applies for the network fluctuation issues. You need to either choose 3G or 4G to avoid loosing your data connection.
Xiaomi that's more than LAME! You need to be ashamed of yourselves.

It happens to me quite often, although not always.
It's more frequent during long calls. If the call lasts for less than a minute or so, it doesn't happen.
Proximity sensor works, and screen turns off as soon as I put it at my ear.
Keyboard is off and not responding for a while. Then, all of a sudden the phone comes alive.
In my case it's not the torch. What I activate unknowingly is the handsfree loudspeaker, which can be even more embarrassing, sometimes.
Maybe it's because I am left-handed.
In an attempt to have the proximity sensor fully covered by my face, I tried to make calls by holding the phone with my right hand, but to no avail, after some time the screen wakes up regardless of everything.

Happens to me too. Although I did notice some differences regarding the position of the phone on my ear or which side of my head I put the phone on, I started pressing the power button long ago to turn the screen off. It may not be ideal, but it takes care of it.
