I'm sure many people here agree that it's very annoying when you're speaking on the phone and your ear accidentally opens up windows and programs or even worse - ends the call!
Surely one of you very clever chaps can make an app that uses the light sensor so that the Diamond knows you are speaking and therefore locks the screen.
It would help so much,
S.
The clever people already did it but because we, normal people, are too lazy to search through, can´t see it

...and this is just one example
I'm aware of this software but how does it work within phonecalls? I'm not talking about when the phone rings, I mean post-unlock during the phonecall...
read the post man, it`s not very large and you will find it like I did
The program doesn't do what I describe above, although the idea is brought up a few times in the thread. It can switch off the screen but i'm talking about the light sensor doing this automatically...
The Diamond already turns off the screen when you hold it to your ear (by using the light sensor)...
I thought the diamond shut off the screen on speaking/connecting the call? Plus, it doesn't turn back on without pressing the power button...
the light sensor is not sensitive enough for this use.
:-( Damn! That's a shame.

Interesting, the light sensor of my phone can do this. Initially, the screen turned off whenever I picked up a call. I found it annoying because many a times, I need to use the screen to key in some numbers (pin, a/c numbers, whatever). Then, I used Adv. Conf. to turn this feature off. And I found it even more annoying as I actually hanged up twice by my ear accidentally touching "end call" button. Now, I turned this back on again.... still annoying but less....
I think your light sensor should be able to do this. Maybe you can check this feature on Adv. Conf. to see if it's turned off by accident.
The only things that were turned off in adv.config were 'sleep during call' and 'fast sleep'. I have switched these on and the screen does switch off but is this due to the light sensor? I now use S2U2's feature to switch the screen off as it's faster (screen switches off on connection)...
But, with all these options, I also find it annoying when I have to key in my pin etc. That's why utilising the light sensor so when you take the phone away from your face it switches back on, would be great.
this is really funny! some ppl want this thing off and some ppl want this thing on.
for the record:
the diamond is by default switching off the screen after a few seconds. when i said the diamond i meant the light sensor.
now, from the history:
long, long time ago (about 3-4 months ) the devs here were trying to switch off this feature because if you have to dial one more number or want to switch yr speaker you'll face a black screen (just touch the middle/enter button and you are back in business). some said it is the light sensor, some said it is a timer.....mostly they tried by registry tweaks, don't even remember who was the first to succeed but it was a great victory ...hahahaha
today we have a few options. one of them (the most popular one i think) is schap's advanced configuration. another was is the famous twaek 3.2 (today is 5?).
on the last month we have a few ROMs that already had this tweak built in. i think our friend here has one of those ROMs of them (because he ha sit tweaked already).
m8 i think you can switch this option back to default (switch off the screen) with the advanced config tool.
this one is an example (i think this one was the first):

and so on ....everything a search away (i used "screen+call")
Thanks for the post, my issue wasn't how to get the screen off during a call. It was what causes it to go off and if it is the light sensor, could an app be made so that when the phone is taken away from your face, the screen switches on again.
I agree. I would love it to switch off as default, but also TURN ON when I pull the phone away from my face... I can't understand why this is not the default behaviour. I have some time later on this month I will look at this more carefully and possibly program the solution.
Sprint Diamond
I agree that would be great. My screen on my Sprint Diamond has never turned off during a phone call. I didn't even know that was a feature on some diamonds until this thread. I have tried making a call and then covering the light sensor but nothing happens. So, here is my vote for the ability to get a screen that turns on and off as you put it to your ear and take it away.
just work exactly the same as iphone and the problem will be solved.......
The main need for the lock screen is in the following situation:
Phone is in your pocket (or bag), a hard key is accidentally pressed, the device wakes up. This by itself is not a problem, since without anything else happening the device will go back to sleep, but, if another hard key is pressed while the device is active (screen press can not happen while in pocket, since it's capacitive), the device can start do annoying things.
Now, if the proximity sensor can be designed to switch on when device wakes up, and put it back to sleep (immediately) if device is in pocket/bag, this will kill the need for a lock screen. This is totally possible and just awaits the programmer who wants to make our lives easier...
hm. try pocketShield?
it locks and unlocks your device by use of the light sensor.
Interesting. I will use it for now.
The problem with using a light sensor is that if you use the phone in the dark it won't unlock. Proximity sensor won't have this problem hence it's a better sensor for the task.
Apparently this will happen even without the help of the XDA community...
I've just sent the following email to PocketShield:
Hi,
I would like to know if you are working to utilize the HD2's proximity sensor for unlock (like you did for Omnia). If so, when should we expect a version with this feature ?
Thank you very much.

This is their answer:
That’s the idea, but can’t confirm that yet because we are not sure if hooking into the proximity sensor will be possible. Hope yes, as in Omnia2. Just received our new HD2 today and will start to dive into it next week.

You are wrong about one important detail though. The screen is very sensitive and can easily be pressed through the lining of your pocket, and even through fairly thick fabric like jeans.
it's a capacative screen...
capacative scree = no stylus/fingernail/penny/spoon
it wont be acvitating throught screen contact.
impossible. (unless you have rrrrrealy thin pants, and the current can pass throught them)

hi, the pants didnt have to be that thin. i think the hd2 screens also vary a lot, in being more or less sensitive. another thing is that people are deifferent when it cames to electric fields. also sweating can affect the display. i startet programs and other touchscreen things already, when the device was in my pocket.

In the case of Pocketshield, it won't. Because all sensors only turn on during a short period of time (seconds). Once you unlock or turn off, sensors go to sleep. This is one of the reasons why "auto lock" is not possible, because that will indeed involve a permanent monitoring on the sensors.

You don't know what you're talking about. I didn't say it was sensitive to pressure, but rather that direct contact between skin and the screen is not necessary. Holding my finger on one side of the fabric, and the other side of the fabric touching the screen, this is registered by the screen as a touch EVERY TIME. There are maybe materials that completely isolates the screen, for other materials it probably depends on how thick they are. For me it is certainly possible to influence the screen even through pretty thick cotton fabric (maybe other types of fabric too, I wear mostly cotton), leather, and even paper. Just to test it, I just did a slide to unlock my HD2 through a pile of papers (granted it wasn't a very thick pile, only six sheets of paper thick), and through my leather shoes (this was a little trickier, I had to to make sure that my foot made good contact with the leather at the point where I was sliding my phone across the shoe). i can interact with the screen through normal denim jeans fabric without any problem, and the pocket lining of trousers are usually quite thin, so accidental interaction with the screen seems almost unavoidable if the screen is unlocked in the pocket.
I have actually had some problems a couple of times when the slide to unlock had been deactivated on my HD2. I once took my phone out of my pocket and it was at the confirmation screen for factory reset, and I have actually had the phone hard reset on me once which I suspect may have been caused by the slide to unlock being deactivated. I would never knowingly put an unlocked phone in my pocket, and I wouldn't recommend it to anyone, but you're welcome to do as you please.

oh, i didn't know it was that sensitive, then, i can really see a need for an apps like this.
but, what about just a normal case? slip it in and out? i mean, i think that COULD solve your problem in a 'no thrills' sorta way... but it wouldnt be as exciting now would it?

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.
sometimes my phones touchscreen becomes unresponsive when its flat on its back on a table for example. I unlock the screen with the trackpad or power button so that the screen comes on. Then when i try to slide the lockscreen it doesnt do anything. When i begin sliding the bar from the total edge of the screen it sometimes works.
Usually i just have to pick up the phone to get the touchscreen working again. actually, when i even lift up the phone the slightest bit, it works again.
Weird right?
anyone else experiences this issue ?
I assumed it was designed to work like this. Makes me move my phone rather than just slide to snooze the alarm then go back to sleep.
Same here. I think it has to do with the capacative toucscreen.

you're saying you move your phone to snooze the alarm? didnt know it could do that, gonna try that out tomorrow morning
forgot to mention the issue is not ROM specific. I have witnessed it on virtuous, CM, MIUI, stock
Ive had this problem as well. Slightly annoying!
I don't think its a design issue..
you don't have to lift your phone to get the screen to respond.
notice that it is enough just to touch the body of the phone to make the screen responsive again..
for me its very annoying, especially not being able to snooze the alarm in the morning
Let me point out that this happens with my G1 also so its not just the G2.
Yeah, there are a few discussions about this on the forums already. It's most likely a capacitance issue. When your phone is just sitting on a table and you touch the display, you may not create enough capacitance with the touchscreen for it to register as a touch (as opposed to resistive touchscreens which needed only physical contact but were less accurate as a result). Touching the body of the phone basically creates a common ground or voltage reference point for the phone, allowing your finger to create the needed amount of capacitance (in technical terms, no longer a floating ground). Whenever I touch the screen while the phone is lying on a table, I just always make sure to rest either my thumb or ring finger on one of the edges.
A lot of factors will also come into play---whether or not your phone is in a case, type of material the phone is resting on, the level of humidity in the air, even potentially the type of shoes you are wearing. This is why sometimes it works and sometimes it doesn't.

This seems to be temperature related (and it doesn't happen on a mytouch 3g)
I live in Minnesota and I deliver pizza. When I would need to call a customer to get into an apartment building, I would set the phone on top of the pizza bag and dial with one hand.
When I first got my G2 (early november) I had no problems doing this, then one day it wouldn't respond at all to touch. I still had my old mytouch 3g with me because the old number wasn't ported yet, and I was able to use that to make the call. It wasn't until later that I realized that the problem was caused by the cold and that I needed to touch the metal part to make it work, so I thought that the touchscreen on my 2 week old G2 had just died.
At room temperature the touch screen always works (I can silence the alarm while it's sitting on the table), but temperatures below 50F cause problems
I started noticing this as well. Sometimes I'll hit the power button to turn my phone on from idle-state and then I'll drag the unlock button with to no avail! But then again, I do use my thumb to do it so maybe the capacitance by using the thumb isn't good enough to unlock it.
I use my phone at work a lot so in order to text while being discreet, I usually have the phone in my right hand and text / unlock the phone using my thumb. I doubt it is a defect but it had me worried too. Guess I'm not the only one experiencing this. (Although I must say, dragging my thumb to swype and using the side of my thumb probably is the reason why it sometimes doesn't work)
Back when I had my g1 it did the same thing and experience this on my g2....if its laying down its like it thinks its just on in your pocket so the touch seems limited

Not weird. TOTALLY normal and expected.
It is because it has a CAPACITIVE TOUCHSCREEN.
This means that when you touch the screen, your finger is actually COMPLETING AN ELECTRIC CIRCUIT.
When the phone is lying on a table and you touch it, you are NOT completing the circuit since you are NOT touching the phone's body.
When the sensor is on, there is an electrical difference between the surface of the screen and the body of the phone. When you touch BOTH, you alter the electric field in that localized area of the screen. The sensor detects the change in voltage and determines the location of the contact.

So how do I adjust the sensitivity? As I understand it I could increase the voltage to the screen making it easier to complete the circuit...such as through thin gloves.....

This is mostly true.
Put the phone on the table and dont touch it and try to swipe to unlock.
No touch a finger on the phone body and do it again, itll work.
Doesn't seem to always fit that behavior, but more often than not.

You don't. You should NOT even if you could. It would not work as you expect since it is NOT a matter of sensitivity, but of CONDUCTIVITY.

Someone was just pointing out that if this was "precisely" true as you put it, then the screen should never be responsive if you aren't touching the phone's body (since the circuit is, based on your reasoning, still broken). This isn't the case though since it does work sometimes. How could your statement be precisely true if it's known to be false sometimes (hence the "mostly true" comment)?
And it's actually not true. You are not completing an electric circuit. No current flows from your finger into the screen and no components within the phone are electrically coupled because of your touch. As you stated, you are altering the electric field when you touch the screen. This results in a change in capacitance in that area. Note, this change occurs even when you are not touching the phone's body, just to a different degree. Touching the phone will typically increase the amount of capacitance as opposed to when you are not though (since you are basically "grounding" yourself to the phone). The more capacitance there is, the easier it is to measure. If there is too little capacitance, the touchscreen's microcontroller will not register the change at all. Even if it does register the change, there will be additional filtering that occurs to that raw data either in the microcontroller itself or in software (or both).
This is why the screen works sometimes when you touch it without touching the rest of the phone. You are still causing a change in capacitance. The amount of change depends on numerous factors (this is what I stated in an earlier post). These factors effect how grounded both you and the phone are relative to earth ground (in the electrical sense, not geographical). Typically speaking though, if you are relatively close to earth ground, then you will be able to use the screen without touching the body of the phone. For example, someone stated earlier that the screen doesn't work when it's cold. Cold weather results in lower humidity/drier air and you being less grounded (basically why people see an increase in static electricity as well). Chances are that the touchscreen would work again without the touching the phone's body if you had physically been touching a large piece of metal with your other hand (to help ground you).
So in response to the other question posed, yes, technically by raising the voltage level to the touchscreen, it may result in a more sensitive screen since there will be a larger increase in capacitance when you touch it. It may also reduce the life of the touchscreen though, if not damage it completely, so not a good idea. It would be better to figure out the filtering mechanism if possible and adjust that in software. Not sure if any devs have looked into it (though my guess is that if it was simple, it would have been done already).
I am so happy I found this thread..
Lately I thought my touchscreen was broken because I was unable to snooze my alarm in the morning (just as some of you seem to have been trying to do).
I think it's temperature related as suggested by the person who mentioned pizza delivery.. and I think this because it only happens on mornings where I've left the bedroom window open and it's very cool. My phone is often on a cold wooden surface. however even picking up the phone doesn't seem to help (I'll have to pay more attention next time) but after a few moments of struggling it eventually works (probably warms up in my hand and gets a better circuit).
I can also vouch that the screen works great with just a single finger on a flat surface, provided it's room temperature. I don't need to touch the body at all, and I do this a lot without issues (aside from cold mornings waking up to my alarm).
Right I have now had this issue several times and it has become a big problem. I put the phone in my pocket, get a call/message/text/ which turns the screen on, and somehow the touch screen buttons keep getting pressed. So far I have lost all my paid for credits in a game when I paused it and put it in my pocket to get off a train, had it start skipping tracks when listening to music when a message arrived and it started pressing the lockscreen music buttons while in my pocket....twice.
I never EVER had anything like this with the S3 that it replaced. Somehow the screen is obviously being pressed by my leg THROUGH my trousers and activating the buttons on the touchscreen whenever the screen is on. Obviously this may have serious consequences if it starts calling contacts or even emergency numbers while in my pocket.
I am looking for a way to reduce the sensitivity so it doesnt do this but so far all I can find in the settings is a single tickbox to INCREASE the sensitivity so you can use it with gloves on (which suggests to me it must also be possible to reduce it).
Yup

You may have a faulty handset as I don't have these problems on mine.

I doubt it. Friend has one as well, does exactly the same, rub phone on chest to clean it and it is pressing buttons/icons etc on the touchscreen if the screen is on.
Did you turn out that thing in settings that makes the screen more sensitive so that you can use it with gloves on?
There's the air wakeup setting too

I've owned the S2, S3, S4 and never had this problem. Now I have a G900F. The S5 screen is ridiculously sensitive and I have the exact same problem as the OP.
Try to add a pattern lock screen, it should prevent the phone from launching anything even if the screen wakes up.
Yeah I've been having the same problems I switched the touch sensitivity toggle off and it's been ok

It' on pattern lock. That doesnt stop notifications coming up for anyone that has it set up like that, and it doesnt stop it pressing the emergency calls button!
Air View is off, Increase Touch Sensitivity is off (as already mentioned). Infact I tried the Increase Touch Sensitivity option to see what effect it has and I can't see any difference to it with it turned on, it is just as sensitive, I can literally put my finger inside my shirt and move the screen around and I can do this just as well with the touch sensitivity on or off. Perhaps there is a bug which is causing the increased touch sensitivity to be on ALL the time even when the box is not ticked. Seems to be a problem many are having anyway.

Not had any problems whilst in my pocket, but I tried using the screen through my T-SHIRT and it does the same thing for me with touch sensitivity off or on. Just tried with gloves though and it doesn't work unless you switch touch sensitivity on, so it does make some kind of difference to the screen.

In that case ewokuk, 2 solutions, since your phone is brand new, maybe you should take it back to your store and get another unit.
Or wait for maybe a fix with next firmware update.. which may happen anytime. For helping you, you could get a protection / front cover for your phone
I registered just to post here. This has been driving me absolutely nuts. Every time I have a call when in the car and the phone is in my pocket (talking through bluetooth), if my leg so much as twitches I end up muting myself or hanging up. I went from an S3 to the S5. If I get a text while walking and I have music playing or something, any and every button available will be pressed. I have had random gibberish created on my calendar while walking (screen lock hadn't activated yet because I had just put it in my pocket).
ewokuk, any word on what you did? I have played around with as many settings as I can but nothing seems to do the trick. It's a nice phone, but unfortunately this one thing drives me up a wall
The screens can still be used through simple fabrics .. it can be done so since the S2. If the screen is in the pocket facing down (against your thigh) it still can be triggered. I can only suggest to put the screen facing outwards or well not against your skin or body

The difference in sensitivity between the S3 and S5 is pretty astounding though. Yes, I could use the S3 through a shirt if needed, but I never had it hang up phone calls constantly and go through all my apps randomly.
I think the proximity sensor is just not the greatest as it doesn't detect that it's in a pocket. Again, no real idea, but that is my guess.
Same problems here. Phone pocket dials people, replies to texts. Pattern lock helped..but I prefer not using it. Maybe it's because the phone wakes with text messages received. Annoying as heck

I'm glad I'm not the only one because I really did think it was just me. All of the issues listed in this thread happen to me all the time. Tracks skip, the phone hangs up.. I even find my typing is less accurate unless I really slow myself down (it seems prone to picking up extra key presses although this might just be mel. I did not have these issues with my s3.

s series sensitivity
I have had that problem with the s3 s4 and now s5 i just put my phone in my pocket with the screen facing out that way my leg cant activate it and my pants doesnt press the unlock button when i move.
Ditto, never so bad as this phone, I put it in my pocket now screen out, and put my wallet over the screen so I don't accidentally crack it.
Often in games when I am "hovering" over the screen it will trigger the action anyway. I've tested this to nearly 1 full cm away from the screen. If I hover on the same spot for 2+ seconds at ~1cm it initiates a touch at that point.
I also did not notice a difference switching increased sensitivity on or off.
Rarely, but sometimes during calls the screen turns on briefly when I pull the phone away as it starts making my face sweat, it will the "hover" hang up or mute, or launch some app (often one that has force screen on permissions) and send people gibberish email or text messages, set alarms or calendar events. I even had it start a conference call, adding an old boss to my conversation (I keep the number handy for references) once.
I have used the finger print lock since the first time I turned the phone on. Most annoying is the sensorly app, only works with the screen on even when running in the background...
I have also had to modify my typing to accommodate this sensitivity, I have to tap slightly above and right of the keys to make sure I hit the right ones.
