The Desire seems to quite blatantly have a light sensor due to the automatic flash, buttons lighting up in low light and automatic brightness setting.
However, I can't see the sensor on the phone?
Any idea where it is?
I think I read something somewhere about it being above the screen, next to the HTC logo. Gee, I'm SO useful
If you hold your screen agains the light at an angle, you'll see it.
It's on the left from HTC logo -- directly opposite from where LED light is.

Anyone having a issue where their keyboard doesnt always light up? or it stays lit, then shuts off?....is it sensor reactive? to light? iunno. my keyboard doesnt light up all the time.
Same issue here

It seems to me to be a sensor oriented thing. In dark it lights up no problem but when in a room with light it shuts off to conserve battery? Very interesting htc.

The light sensor is in the very very top left of the screen. When you have the keyboard open and are in a well lit room you might accidentally be reaching over the light sensor, making it think it's dark again, and therefor powering up the keyboard backlight again until you move your finger. You can solve this problem by rooting and installing Cyanogenmod RC1 which gives you complete control over all your backlights.
Agree with jark99. Looks like it depends on light sensor. In the dark environment keyboard lights up every time.

Want to know what's even cooler with that light sensor? When I hold my phone to my ear, the screen goes off. When I take it away, it turns back on. That's pretty darn cool. However, yes, it's all dependent on the light sensor. I've had a few times when I wanted to light on and it didn't, but that's rare. I kinda like that when I need it on its on, but not when I don't. Every bit of battery is important when it comes to my phone, but there hasn't been a large problem with it not coming on here on this end.
I couldn't find the original thread about this, so I'm making a new one

Theres a video where i film after the 1.28 patch, and as you can see the top isnt making that weird thing anymore, Its just the screen flickering or how i should call it.
You barely see it, but you can see in the video that theres something happening when im moving up and down.
i think the problem is by the ambient light sensor beside the hTC logo
so when your fingertip pass thru the sensor, the light enter reduce so it become brighter...

What is an ambient light sensor on a monitor?
It Is A Sensor That Detect Light So If Its Dark Your Screen Monitor Brightness Will dim down so you're not looking at one source of extreme bright light, When Its Bright The Screen Monitor Will go up to compensate for the extra light around you so you can still see the monitor comfortably

No, that's not it. It's a software bug, the fixed it just a little. It's probably driver problems still. If it was the light sensor it would just dim, not blink.
still the bug is there.. but less than before.. mine screen flickers (not the screen flicking bug) when the bug hits.. just in an instance.. and distorted the date a little than before.. updated to 1.28.415.9 Arabic version
Well mine still makes the thing where everything in the bar gets all blurry.
Just not as often.
So the bug is still there but they sure did something to improve it
Edit: yeah ayan15 did a good description of my bug

My notification light is demonstrating strange behavior. When the screen is on, the light is fine. After the screen has been off for a few minutes, the notification light dims out to about half its normal brightness. If I turn the screen on, the brightness is restored.
I've looked through the settings and don't see anything to control this. Is anyone else having this problem? It's pretty minor, but it makes it harder to notice in day/light.
I discovered some interesting behavior by the LED notification light on our phone since the JB update. This isn't a bug since I can confirm it is repeatable and seems to have a purpose.
Okay so while your phone is on the charger you know how the LED light comes on if the screen is off? Hold the phone in your hand and make sure the screen is on. Turn the screen off with your power button and notice the brightly lit LED light (red or green, depending on your charge state). Now, turn the screen back on and set the phone down on a flat surface. Turn the screen off again now and notice the LED is much dimmer.
Another thing to try is to turn off the screen while the phone is in your hand to get the bright LED and then set it down. The LED will set itself to a dimmer state after some time goes by. Cool, huh? Seems to be designed that way to more efficiently sip the juice while charging.
Class dismissed!
EDIT: poit correctly determined the reason behind the intensity of the LED light is directly related to the ambient light in the phone's immediate environment. Kudos to poit!
Cool.

The LED brightness seems keyed to the ambient light sensor. It's it's in a dim environment (or you have the sensor blocked) when you turn off the screen, the LED will be dim. If it's in a bright environment when you turn off the screen the LED will be bright.
Mine didn't change at all stayed dim. Got me thinking though, could it be adjusting for how bright it is?
It sure does if I go to a bright room my indicator is bright. Dim room and a dim indicator. While charging if you set the phone down if and while bright it will go dim.

I believe you are correct. I thought it had something to do with gyroscope sensor(hence why it was dim on a flat surface). But I just tried it somewhere with more light and your assessment is correct. Bright environment equals bright LED. Dim environment equals dim LED. Still cool!
:good:
P.S. - this is best tested in a dim room with a lamp you can shut on or off. Lamp on = bright LED, etc. The LED will go back and forth while you play with the lighting.

Or you could just cover the light sensor like I just did and then remove your hand.
The notification led is connected to the ambient light sensor so in a dark room the led is dim, in a light room the led is bright.
However if you're out and about in even a slightly bright day and take your phone out of your pocket (which is dark) you can barely see the led because it's been in your dark pocket.
This isn't a hardware limitation, if you install Resurrection Remix or Liniage OS the led is bright all the time.
I'm running a stock based custom os because of the camera quality.
I just wondered if anybody has worked out a way to either disconnect the led from the ambient light sensor or even disable the light sensor all together... I don't use it.
I've tried the Xposed Sensor disabled but it didn't work on either BRF5 or ARC5

Turn off Automatic screen brightness? Is the LED not connected to the screens brightness level?
Ummm, actually when I said I don't use the light sensor, I figured it was obvious that I don't use automatic screen brightness (since it uses the ambient light sensor).
Anyway, no.. The led isn't connected to the screen, it's connected to the same sensor as the screen... The ambient light sensor.
You can tell the screen to ignore the ambient light sensor by turning off automatic screen brightness, that however doesn't turn off the sensor.. So the notification led is still controlled by the light sensor.
Have you tried any of the notification apps on Play or Samsung Appstore? There's quite a few free ones available on Play but I've never had the need to try any on this phone.
I've tried them all, I like lightflow the best.
They let you control the brightness up to 100%, but that's 100% of the brightness controlled by the ambient light sensor which in turn answers to the Samsung software.
*Sigh*, if I can't find an answer, I might take my balls in my hand and open one of the phones and physically disconnect the sensor.. It's only a cable with a plug.
I also have an S8+ and it does the same thing.

LOL, if you do let us know how it comes out.....the sensor not the balls.
Has anyone solved the troublesome problem?
