Light Sensor request for HTC Blackstone / Touch HD

I am looking for a light sensor solution like on the IPhone. If u get a call and you put the phone at your ear, the phone screen gets dark, thats normal,
but what is, if I want to turn on speaker or something during a call? I allways have to press the ON/OFF button.
At the Iphone, they got a better solution for that.
Can anayone manage a little plugin cab or does anyone know a registry solution?

you need Touch_InCall_Screen_Tweak, It can do what you want but it is not using the light sensor.
It uses the G-Sensor, when the device is not in vertical position (closed to your ear), phone will wake up automatically and sleeps again when you take it close to your ear to speak (vertical position).

thank u for your reply, but I want a light sensor app.

Am not sure
but there isnt a light sensor in the blackstone to start with

i think you'r wrong m8 ... From what i know there is a light sensor in blackstone

the blackstone has a light sensor next to the ear speaker. It is oossibble to turn it on. but wehen you remove it from your ear, the light does not turn back on

Search for "PocketShield", this program has the requested feature, and much more.

yes, 3.0 is very cool

Pocket Shield is not freeware and is definetly not what I want.
I just look for a solution auto-lock un-lock when you remove or taken to the ear.
Microsoft developers will read this thread and bring it into new builds.

Ok, try this one. It seems to be available for free or at least the minimum version ,the full version is around the 7 $. You can measure the Brightness at your workplace, in rooms, use it for Photography or to set up aquariums and terrariums. Works fine although I use it just like for fun maybe is useful for your work.

I dont want a Luxmeter, if I want a Luxmeter than I take mToolbox.
I tried Pocket Shield and after uninstalling this program, the light sensor does not work anymore.

Try TICST
really, just try it.

This is what you want to adequately switch the screen off as it comes to your ear and then on again as it comes away from your ear.
I've been using it on a an HD since March/April and it works flawlessly. It even has intelligent options to handle bluetooth calls and control of the speakerphone.

hmmm sounds good but what happens if you get a call at night and there's no light?
Need a combination of light sensor and g-sensor I think.

Yes it has it - please just try it before finding problems with it. It will work for you!!!

Yes this is one of the biggest problems with lightsensor...
Tested the detection range with mToolbox and Lumos - and it shows "0" very early even if there's a bit light around - so the light sensor in-call-detection wont work very good.
How is it solved at iPhone?
BTW:
[APP]Touch InCall Screen Tweak v1.2.0 - Updated 3 Sep 09 - Battery Drain Fix
So it doesn't use the light sensor then?
From v1.0.6 it DOES use the light sense to detect if it is against your ear. This is really a double check to back up the orientation. It doesn't use it to determine if it's away from your ear because the sensor doesn't seem to work when the screen is off, so it's of no use for switching the screen back on.
so - what else you want?

The iPhone doesn't use the light sensor to toggle screen, it uses proximity sensor - it turns off the screen when something approaches the area near the speaker and turns it back on when there's nothing near it.
Light sensor can't work reliably because you can get a call in a dark room.
TICST is a workaround using both the light sensor and the g-sensor, it's rather good but not perfect.
A perfect solution requires hardware that's missing in Touch HD. HTC HD2 will have the proximity sensor so screen toggling will be working there, hopefully.

Face Recognition App

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

That'd be awesome

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

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

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

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

So what does the motion sensor do?

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

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

It is turned off via proximity sensor not accelerometer

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

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

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

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

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

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

nope again!

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

dark screen when have phone call

Hi guys
Since one day , my screen turns dark when having phone call or receiving phone call.
I can't type the keyboard and press the speaker button, which are inconvenient.
I have updated fw to fw_capricorn_miui_MI5S_V9.6.1.0.NAGCNFD_857fde8b41_7.0.zip
I have this issue on different roms including lineage 14 , lineage15, RR,and pixel experience .
Do anyone also have the issue and do anyone know how to solve it.?
My phone drop to ground once which cause screen crack. I am not sure whether this is the root cause.
Many thanks

The phone has on the front a proximity sensor, which is basically a small light sensor that checks if the phone is near the head or not. If it's near the head, it turns the screen of, so that you don't press any buttons while holding the phone to your ear.
I think either your sensor is broken or the crack always brings light to the sensor.

Could I disable this function?
Always disable light sensor or disable when have phone call

I had the same problem I thought the sensor was broken (you can test it with sensors test https://play.google.com/store/apps/details?id=asd.vector.sensor ). But it was ok, it turns out it was firmware related. When I downgraded my firmware the proximity sensor was working again...
Good Luck

Front IR led blinks continously

What is the countinously blinking IR led in the front for? By looking at the notification LED area through anothers phone camera, which is a bit sensitive in the IR, one can see the blinking IR led. Is it for focusing with the front camera? I did not activate facial recognition yet. Actually it is blinking all the time, even when the front camera is not in use.

Ok. But the proximity sensor is always on. Always. Even when the display is inactive. I reseted the system to factory settings and at some point in the process the sensor turns on and it stays on non-stop if the phone is on. Is this normal?

It's always on to check if the phone is in a pocket or not. That's completely normal. When it's in a pocket it disables aod to preserve battery. It doesn't consume battery at all and it doesn't do any harm.
Edit: also disables touchscreen when you're talking on the phone while next to your face.

Proximity Sensor on Samsung A50

I'm pretty sure our A50s don't have a Proximity Sensor.
I don't use smart stay, but I do notice on phone calls that the screen sometimes goes from black to on at random times during the call. Is anyone else experiencing this? It's driving me crazy!

I think pretty nothing as it is irrelevant. It is simple on/off switch for dimming screen when phone at the ear.

I guess so. I've just never noticed it so much with any other phone. I don't usually press my ear right up to the ear piece though. Usually I have about 1-2cm distance. Is there any way to increase the screen cut off distance?

The proximity sensor which we use in the mobile phones are with the capability of sensing any object comes in front of them . The longer it can sense is about 5 cm. The proximity sensor just sense the presence of object (within 5 cm) and not the distance between them . So it's normal.

Proximity sensor is there
Proximity sensor is present in all the phones and it is also present in Samsung galaxy a50 just that is very small and is present on top of the front camera..
By default the proximity sensor should be on for every phone but samsung galaxy phone in software it is off..
to check if your proximity sensor is on or off you would have to dial *#077692# in your keypad and the proximity sensor screen will open.. there you can the status.. if it is off there is a small button on top which would turn it on.. to check if the sensor is working properly.. put your finger on top of the front camera and if the screen goes green then the sensor is working fine without any issues..
Hope this fixes your concern..
