[IDEA/REQ] In-Call Lock Screen with Light and G-Sensors

Hi,
I recently bought a HTC Touch HD, and I think that the "shutdown-screen-when-you-answer-a-call" function of phones like Diamonds, Touch Pro and HD is the dumbest way to prevent accidental presses on the touch screen.
Our devices have a light sensor, that could be used to switch off the screen if the phone is near the ear (like the phone using an "i" word ) and keep it on when you answer with loudspeaker for example.
The "problem" with this function is that when you're already in a "no-light" environment, the screen lock function doesn't work.
To resolve this issue, I think we could use the G-Sensor. Indeed, if the place has no light, then, the phone cannot detect the proximity of a ear. But when you put the phone next to the ear, you hold it a the vertical...
To make it short, the app should do :
Do nothing in normal use.
When a call arrives :
- it monitors the ambient light
If there's light :
- when you answer the call, if there's light then no more (you stick the phone next to the ear), it switches off the screen and continue to monitor.
- while in call, if there's light again (you want to see some info on the screen for example), it switches on the screen and continue to monitor.
- and so on until you end the call
If there's no light :
- when you answer the call, but let it at the horizontal (you let it on the desk for example), it does nothing
- if you take the phone on the vertical position (you stick the phone next to the ear), it switches the screen off.
- if the phone, during a call, goes from vertical to horizontal of horizontal to vertical, the screen is switches on/of
- and so on until you end the call
Obviously, you could replace the "switch on/off screen" with "lock/unlock screen".
What do you think about ?
UPDATE :
After playing a bit with the HD, it appears that HTC DOES use the light sensor for turning the screen off during a call.
Let's do a test :
In a place with plenty light :
- put your mobile with the face up
- call a number (always face up) : the screen will not be switched off until the light sensor detects a loss of luminosity or a timeout set in the registry.
So, my conclusion is that HTC already use the light sensor to switch the screen off during a call, but they do it in an absurd way :
- they poll the sensor just to shut down the screen, not to switch it on.
- once the screen has been switched off, they do not longer poll at all.
Do you think it could be a way to "hack" their system to do what we want to do ?

no one has an opinion on this idea ? if there's nobody that want / have the time to develop a soft, I understand, but at least please, give me just your opinion

I agree with your idea for such an application. I must admit that I am very used to just pushing the power button when I answer a call (from Polaris use) to ensure I am not going into other programmes as I rub the phone against my ear. On the other hand I am trying to get used to the Touch HD's modern automatic method but I can't help not feeling relaxed that it has worked and keep trying to look at the screen in the corner of my eye to see if it did go off or not.
If it does not come now I am sure there will be such an app very soon just as you describe especially as all the latest models now have it.

i'd use the half of it that doesn't require the G-sensor as i don't have a diamond or HD...
but i'm certainly sick and tired of my ear operating my touch screen while i'm speaking.

I've written a prototype to do exactly what you are talking about although the one crucial part I am missing is the lock code. Every example or suggestion for locking the screen is very hacky and never feels like a good approach. If anyone has a good solution for locking the screen (especially in managed code) I would be happy to complete what I have started and release it with source so it could be improved upon.
So far, the best locking utility I have seen is PocketShield although I'm not sure what approach was used for locking in that case. It almost feels like a form that captures all windows events but I'm not sure exactly.

Maybe the simpliest way to "protect" the screen is to switch it off. I suppose it must be some API to do that ?
Concerning the "locking", I think the simpliest way is to put on focus an empty window (transparent if it can be ).
I'm really happy to know that you're working on an app like that

Thanks!

We need this app, how does the iphone acheive this?
I think the 'easiest' way to make this app would be to keep the phone doing what it does currently (put the phone on standby when answering a call) then have the light sensor take the phone out of standby when it receives light, (taking it away from your ear)?
Obviously if its dark then we would have to use the power butten as we currently do now or have the Gsensor do it with a twisting motion (vertical to horizontal).
If anyone has an idea how to program this i'm willing to help in any way, the current systems seems so crude on such tech devices!

There a program, that can help you. Not full, but it can switch off screen, using g-sensor. However its using not vertical aligment of the phone. There are using changing orientation of the phone to decide when phone near the ear.
http://forum.xda-developers.com/showpost.php?p=2622590&postcount=45

I have always wondered why our WM phones don't do what the iphone does...
For the SE Xperia X1, the light sensor is right near the earpiece (along with the little front facing camera), so it would go to virtually 100% darkness when near the ear. I would presume unless you are using the phone also in 100% darkness (which should be pretty rare I would guess) then it would work like the iphone.
I have also been quite annoyed by the fact that after a phonecall, sometimes I found i'm in a note taking program or weather program or something else. It just seems dumb, considering our phone HAVE these lightsensors?!

I think it's a fantastic idea to solve a VERY FRUSTRATING PROBLEM

I would rank myself this way:
Not a newbie who's just gotten a touchscreen phone and is now discovering the quirks when holding screen to ear,
and not a developer,
but a power-user. I have installed all sorts of XDA-developed features/enhancements for my phone.
But now I have 4 years experience -- starting with the T-Mobile MDA, and its successor, the T-Mobile WING. And despite all of the advancements expected in that time, STILL, I inadvertently end a call, or put it on hold accidentally, ALL THE TIME. Between that and trying to retrieve the phone from my pocket just to answer the damn ringing phone, I would say I have, on the average, a 20% success rate -- and 80% of the time the call is disrupted. And at least once a day my ohone, in my pocket, even when using s2u2, manages to REDIAL my latest conversation, so mcuh so that all my friends say "why don;t you get rid of that phone. It does all these whiz bang things but still can't reliably manage a basic phone call.
My most recent experiment was to call someone, then when they answered, press the s2U2 key to lock the phone screen. Only I came to find out from A_C that this is no good: S2u2 does not have recognition that you're ending the call, thus, since it's in lock-mode, the "END CALL" or Hang-Up hard key does not work.
So by all means, I would even pay for an app that once and for all handles the baseline problems of simply making a phone call. Thanks for making this request.

fireweed, have you contacted A_C, author of s2u2 ?
There may just be perfect synergy between the two of you. His "best of breed" screen-lock app is widely used -- and other developers, like supbro, for example, author of iDialer, have collaborated on small code-bits from A_C to solve some integration problems.
If for any reason you are unfamiliar with A_C, go to his website: www.ac-s2.com -- where his apps are explained, and all link back to XDA.
He's even managed to make the screen lock work, yet, have it selectively overridden when you insert headphone jack -- such that his s2p (slide to play) app opens and allows you to switch music tracks etc while otherwise the screen and buttons are all fully locked...

I think HTC does not only switch off the display but goes to standby (phone works independent if you didn't know yet). Your idea is a lot different in terms of programming.

I don't know if it goes to standby : when the screen is switched off during a call, a press on any button switch it on again. In the registry, the key controlling the timeout before the screen is shut off is named "LightSensorToScreenOff" so I think it is just switching off the screen...

Well if thats the case, its HALF of what the iphone does... it turns off the screen based on the light sensor going dark suddenly (next to ear) but then fails to turn the screen back on after you move the phone away from your ear...
Anyone know how to enable this?

Interested in having this feature too. Isn't it possible to have the G-Sensor determine when the phone is vertical and shut the screen and then when it is lying flat to turn the screen back on again. Believe that the Iphone does it this way, not with the light sensor.

Hmm... I never had my ear 'navigating' my phone during in-call before....
I never allowed the screen to touch my face anyway, and the speaker is facing the ear canal, when I receive or make calls...
But i do understand that s2u2 can do what you guys might need, it locks the screen during in call.

I think the Iphone has something called proximity sensor, which senses the distance from the ear to the phone, hence when the phone rest on the outer ear, the phone screen shut off.
Or am I wrong?

No, you're right. It uses an iR sensor to know if there's something near the phone.

[SOLVED] How to force HD2 to backlit buttons...

...when the screen is on? It's quite annoying to search the keys in dark.

i absolutely agree..........m also searching for such tweak.

intresting tweak !....i'm hope someone could solve !

what would be even better is to use the ambient sensor to turn on the backlight whenever the phone is picked up (using the accelerometer)

Yes this annoys me too is really hard to see the keys in the dark more so when the screen is lit up!

It's a good idea, but a little complicated...
Anything using motion just wouldn't be the best, since a lot of people put unit into a pocket, bag etc. Which is means the HD2 is usually moving as a result of walking etc. You might get away with sensing VERTICAL movement, but that is assuming the accelerometer can detect VERTICAL movement and it potentialy could be triggerd by normal movement in a pocket, bag etc. as well.
You might be able to use the proximity sensor with the accelerometer to do this. It wouldn't be perfect, but may work enough for most.
The simplest thing would be to enable the backlight to automaticaly stay 'on' when the device is activated (I don't need light to do this). Add to this a time feature that says only activate if after 6:00pm and before 6:00am. This means it wouldn't activate during daylight, unless you told it too. You would also need to add the feature to 'always' activate as some like to keep it simple or routinely visit dark places.

perhaps get it to light up when input is detected on the capacitive touch screen. that way it wouldn't get activated in a pocket or case. haven't a clue how to implement it but hey.

I really don't see an issue with wanting the keys lit when the screen's on. That sounds like a perfect solution to me. I think using sensors is overkill.

Interested in this tweak too...

Or use (light + proximity) sensor.

so no ideas then huh? i will have a root around through the registry settings to see if there is anything we can use for this..

i will have a root around the registry see if there is anything we can use

waaaaaaay too many "over complicated" solutions to this prob in this thread regarding using sensors etc ... you basically just need to stop the lights from sleeping while the phone is unlocked and on ! so if the screen back light is on the buttons should be too !!!!!!!!

yea thats what i was going to look for...
i.e. if screen is on.. turn the buttons on!!!

bump ! bump bump !

hahahah i was about to do the same

bump! it's a must !

bump from me too!
I am sure this could be done by a small registry change...but the mystery is as to which registry entry to look at!

Found a way to do this programmetically, I'll make a small test app for this tonight. Check back in like 8-9 hours, my boss won't like it if I do it during work time

[APP] Smart Screen Off 2.3

[UPDATE]
Hi guys, after my account was banned from Play Store, I decided to move all apps on Amazon App Shop for free. :good:
Here you can download last version of Smart Screen OFF PRO.
Smart Screen OFF PRO
http://www.amazon.com/gp/product/B014TKA9VQ
I'll add other apps I developed in the next few weeks.
Download Smart screen off PRO User Guide
DESCRIPTION
Smart Screen Off it's a simple and light app which uses the Proximity Sensor built in your Android smartphone to turn the screen off and on automatically
REASON
I decided to code this app when I bought my Galaxy Nexus: this device doesn't have any physical button on the front screen. Being a quite huge phone, it's quite difficult to press the "turn off" button every time I wanted to turn it off and on. So I needed a way to turn the screen off every time I put it into the pockets and off when removed.
HOW IT WORKS
The app itself is a toggle button, to switch it on just press the App Icon. Then every time you put the phone into your pockets the screen turns off.
If you put the smartphone upside down on the table, the screen turns automatically off.
NOTE: It doesn't lock the screen (just like in a call)
REQUIREMENTS
In order to use Smart Screen Off, you need to have a phone with Proximity Sensor (nowadays every smartphone incorporates one).

Nice APP
Even though I don't need this app...(I prefer manually clicking),
it seems really useful for whom use flip cases.
Such as "planner styled" Galaxy Note

Just installed and it does what it promises. Will be useful for me when at the gym I want to skip songs, I won´t have to unlock the phone a hundred times. Obviously the proximity sensor will be working all the time, did you notice a significant battery drain?. And the app name in the spanish version of the market is badly translated. It says "Fuera de pantalla inteligente" where it should say "Apagado de pantalla inteligente".

This is like screebl?

Good app, great idea. I think you should not only use proximity sensor, but things like orientation. I probably wont use this just because it doesn't seem too useful... I sometimes have my hand on top of my phone (near the sensor) and a finger movement can just keep making it blink on and off etc. Use orientation with this, it'd be better.

GREAT APP!

Works flawlessly, thanks alot.

Just installed V1.1 free from the market and it's a bit too sensitive! I hold my phone in my right hand and when I curl my hand over to touch or make gestures on the screen, the display turns off. Is there any way to adjust the sensitivity? I'm running on a Galaxy Nexus running GummyNex 0.7.6 based on AOSP 4.0.3.

UI is useless for lite so remove it, and as long as it has a notification in status bar i will not use this app, can i get v1 back!
2/5 stars
also in v1.2 there is NO way to turn it off :/

Proximity Screen Off never worked properly for me on the HD2 with several different versions of Android (both Honeycomb and ICS). It was quite prone to locking up my phone with the display off and locked.

Can you not trigger it to go to deep sleep. Screen should lock, that would be more appropriate imo.

If u turn off the display only,will deep sleep work?

You have to turn it on in display settings under ambient display. It's turned off by default, or at least mine was as well as pickup to show.

I think he means the feature is broken. It's not working for a bunch of us after the day-one update. It works when it wants to. OnePlus has done nothing to fix this and I'm just about ready to get my money back. Just because it's working fine for you doesn't mean we're doing something wrong.

Yeah, lock screen gestures and single/double tap don't work on the latest update, but I believe they're working on fixing it, going through repro steps right now according to their bug page. I'm sure it'll get fixed soon, and it's not a make or break issue to me by any means.

What version are you guys on?
I'm on oxygen 9.5.5 T-mobile gm1915 not having any issues.

I came here to find this out. It's works randomly.

I don't know what I did, but it is working now. I have rebooted twice and it has persisted so +1 on the issue being random. I more wanted to know if others were experiencing the same behavior. Thanks for the replies!

Having tested this, It works randomly during low light situations, and all the time in normal/extreme light situations, such as outside in the sun or in a bright room.

Yup. This is my issue.

So my double tap to wake completely stopped working. Single tap doesn't work at all either. Not happy at all right now. Completely stopped about a half hour ago. Reboots fix nothing.

Got my phone yesterday and rooted 10 min after opening it and took update to 9.5.3. no issues at work double or single tap to wake. Used it all night setting it up and playing with it. Lit room or dark. It's been pretty consistent so far. There is an occasional time I have to tap a second time but still work on the 2nd try.
Not sure why it's random like that. Only thing I can think of is after the update... Did any of you do a factory reset? Maybe some reminant install files are causing some issues

The people here saying that it has to do with light are right. I have tested this myself. Even in fairly lit rooms, if the light isn't shining directly on the ambient light sensor, Ambient Display, double-tap-to-wake, and lift-to-wake are all completely disabled. If you shine a flashlight on the light sensor, they suddenly become available. This means that if you aren't using the phone in broad daylight or VERY well lit rooms, you have to hit the power button. Aside from the inconsistency of functionality that creates, I haven't used a power button to wake my phone in 3 years. I certainly hope they plan to fix this soon, as I'm of a mind to return the phone right now. This makes it very annoying to use on a daily basis for me. I keep my house fairly dark at night when I'm watching TV.
For some reason, OnePlus has it using the ambient light sensor rather than the proximity sensor and/or gyroscope for these features. This is not how it should work.

But it seems it's different from device to device ? Double tap to wake, the lift feature and the only one tap to activate ambient light works in all light conditions for me.

Just a thought....is there an option to avoid accidental touches when in a pocket? This might explain why it works in well lit rooms and not in dark rooms.

Yes! That reproduces the issue exactly for me. I am sure this is not the only one, but this thread on OnePlus support forums reports the issue.

You can see users reporting the problems inconsistency, and OnePlus seems to acknowledge the problem and they are "looking into it". Please go add your feedback as I am sure the more people that complain, the higher priority the bug will become.

This is where the inconsistency of the issue occurs... I am in my office which is lit the same way each day since I got the device (low light). The off screen gestures magically started working about 6 hours after I got the phone and were working up until this morning. Put the device close to a light source while the screen is dark, and you will see it wake up with no interaction with the screen. Screen off gestures work while in that lighting. I forced closed, cleared storage/cache of the Ambient display service and my phone now works in all lighting. It is almost as if the sensor becomes stuck in 'pocket mode' or something like that.

I noticed some funny:
Which cases are you using?
I was with the one in the box until now and everything worked fine (ambient display, double tap to wake, one tap to show fingerprint, wake when lifting up the phone,...). I'm with the Nylon case since a few minutes and since then the ambient display won't work anymore.
Maybe there's something related?

The off screen gestures magically started working about 6 hours after I got the phone and were working up until this morning. Put the device close to a light source while the screen is dark, and you will see it wake up with no interaction with the screen. Screen off gestures work while in that lighting. I forced closed, cleared storage/cache of the Ambient display service and my phone now works in all lighting. It is almost as if the sensor becomes stuck in 'pocket mode' or something like that.

Yes, you're totally right! I tested it! When light is shining on the display, my tap gestures will work again. I forced closed and cleared storage of ambient display but unfortunately it doesn't change my current situation, at the moment it won't work... ?

I can confirm this as well. In dark or even dim rooms, I must use the power button to turn the screen on, in well lit environments, I can use tap to wake. Hopefully this can be fixed in an upcoming update.

Speakerphone Screen off

Hi Friends,
Can anyone tell me how do I keep my phone screen on while talking on speakphone? It annoying to turn it on again & again. Is this an issue with device or by default.? Pls help I still have few days for replacement.

I don't think you can do that.
The screen is designed to go off to ensure that voice calls get absolute battery priority because voice calls are more important than a screen that's on. Since we aren't in emergencies this obviously sounds dumb but that is the intended purpose.
You can try making the lock screen timeout to much longer and see if it also applies during calls.
Personally though I see absolutely no reason why someone would want their screen on when talking with someone.

Screen is off because of proximity sensor so you don't touch the screen with the face. It's not a battery saving feature.

Which again comes to the part where I said "I don't see why anyone would want their screen on when talking to someone."
I see it as battery saving as well as preventing accidental touches.
