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

I'm looking for this.. If you find a solution send me a PM, I will do the same
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.
Mods, please move if this isn't the right section (I contemplated the development section but opted against it).
I'll try to be short while providing enough background to get the more knowledgeable people here the info they need to help me with this problem. Essentially, i have a 32gb P6210 that I'm going to flush mount in my dash to use for in car entertainment. With no access to the hardware buttons I did some research on what would realistically meet my needs (especially getting the screen back on without the power button).
I found Tap Tap App on the market and the widget allows me to turn the screen off and waving my hand in front of the proximity sensor four times turns the screen back on. The issue is that, randomly (has ranged from 10 minutes to 17 hours), the proximity sensor is turned off when the screen is off, making the app inconsistent, even with "never turn off sensor" checked within the app. I'm in talks with the developer and he mentioned that the proximity sensor turning off with the screen off is dependent on the underlying rules built into individual ROMs. I'm on the stock ROM.
I need to know if anyone has info on how to keep the proximity sensor on indefinitely with the screen off so Tap Tap App has the input needed to continuing working as designed. I dont care about battery drain at all, the tab will have constant power. I'm rooted with clockwork mod recovery so if anyone has a system file I can edit, a zip i can flash, a tasker profile you know will work, etc, please post it up. Thanks in advance!
Kinda lonely in here...anyways, as an observation update, the app i was using, Tap Tap App, worked far less reliably using the Power button widget vs having the button in the notification area.
Conversely, I found a very similar app called "Soft Power" and have been using it the past 3 days with no issues. It has no widget option and only has the option for turning off via notification area. I'm thinking that always running the notification area by default means a background service is running to keep it there. I have not yet been able to not wake it up by waving my hand over the prox sensor. So for anybody with similar needs to mine in terms of not wanting or being able to access the power button, this has been a good alternative thus far.
I tried it on my phone. It does not work at all.
LG Optimus 2X 2.3.4
It looks like a promising application.
Perhaps it works on ICS ?
Has anyone had any issues using either Sleep as Android or Sleepbot? The screen never fully turns off because the accelerometers don't function with the screen off. I'm concerned that leaving the screen on for hours on end will cause pretty substantial burn-in.

Hey there, I actually made SleepBot and we have an option called "Screen Off Tracking" in the Settings which is supported for newer devices like the S3 or Nexus. Motion and sound tracking will still work even if you turn the screen off, but I recommend trying it out for 3-4 minutes first to make sure.
We've been testing on an LG Optimus (one of the older models that doesn't support screen-off tracking and nothing like burn happens. We dim the screen to all black within 10 seconds of tracking in any case. Email me at [email protected] if you have other questions.
I was concerned about burn-in as well and I use Sleep As Android. My solution was to install Dock Clock. It has an option to make the clock move around on the screen which will eliminate any burn-in and it is very easy to read at night.

So, how about development of sleepbot cause the soft is great
Face unlock currently requires a double tap, which is annoying because it doesn't work half the time
Even though they are trying to fix this in the next update, a better implementation would be when you raise the phone, it shows the lock screen (not ambient display screen), and simultaneously turns on the front camera to face unlock your phone
Gravity screen can do this, but requires a heavy wakelock to do so. Using the same 'raise to wake' method as ambient display [which seems to work without a heavy wakelock], but then showing the lock screen instead of ambient display, should achieve this
I would LOVE this feature, it would be a complete game changer!!
I use gravity screen and don't lose much battery
Use the power button since it's more reliable anyways ?

There's still a fair amount of battery loss. Oneplus raise to wake seems to be able to do the same action without any battery loss
This was so fine on Op5 and 5T. Open Beta, of course!
Update: I've installed the wave up app. It basically wakes the phone when proximity sensor is uncovered
So when I take the phone out of my pocket, it authenticates my face automatically and unlocks, in a split second. I don't need to touch anything
Similarly if I keep my phone face down on a desk (not ideal), when I flip it over to look at it, it unlocks.
No messing around with d2tw which is more like quadruple tap to wake since this functionality is broken

Hi i use the original flip case from OP and as soon as i open my case door it unlocks witch is very easy and convenient.
Shall check with tasker.
Update: could not succeed.
I face no trouble in dt2w it wakes as it's intended to and unlocks with face within a split second, face unlock has become slower since the 5.1.9 and in dp3 but still fast enough
If my hand is dirty i just say Hey or Ok google.
Agree. it would be a great thing

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

In developer options you have to turn on oem unlocking and USB defining. Have ADB and fastboot SDK installed on PC. Then while in the bootloader type... Fastboot oem unlock.

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?

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.
