[Q] Keyboard Backlight - G2 and Desire Z Q&A, Help & Troubleshooting

Hello,
I just got a new G2 today, and had a question about the keyboard back light on it. The keyboard backlight will not work, and was wondering if there was a way to get it to stay on whenever I have the keyboard open. The backlight only turns on when I change my light settings with the Power Control widget, but then shuts off.
Any ideas?

keyboard light is dependent on the ambient light sensor, if it is dark it will light up if it isnt it, it wont

I know that, but I think something might be wrong with it. I was outside late tonight and it was pitch black out, and the keyboard light still didn't work. But I'm not sure. Is there an override mod?

Grab AndroSensor from the Market, it'll let you know if your light sensor is working or not and help you narrow down the problem. The sensor is at the top of the screen so, with the app running, see if covering the sensor changes what light input its getting

Menu Lights on the Evo

The Home, Menu, Back and Search buttons are suppose to light up. But they aren't what gives?
It might only light up in dark places, I know mine isnt lighting up right now, but it has before.

There are some people who's don't light up, go into the closet and see if they go. Of course then you have to come out of the closet eventually
This happened to me. The lights stopped working all of the sudden... and then randomly started to work again. Don't know what the deal is.
They don't seem to light up when charging.

I noticed this too. If you unplug the phone they should turn on.
I thought you had to be in a dark area cause mine works only in dark places. Sort of like ny work blackberry same thing they light up when its dark.

Just confirmed it. There's an ambient light sensor on the right side of the HTC logo. If you angle your phone right in the light you can notice it....

Hah, you're right... I just tested it too, I turned the corner lamp on in my room but the button lights kept lighting up when I waked the phone... I walked up to the lamp, waked the phone up while it's facing me, buttons light up, wake the phone up while it's facing the lamp, buttons don't light up. I'm not sure I would've noticed that if I hadn't read thru this thread, heh.
Anyone know a way to turn these off for good? It's a bit annoying/distracting when watching a movie in low light...

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.

Arc LED Notification light.

I thought the Arc had a notification light on the Battery charging light but cannot find the settings in the menu & when i get a message via gmail, there is no light just a notification in the bar??? Does anyone else get a flashing light if so any idea where the settings are.
Cheers
Just did another test & the led light does flash. But when you press the power or home key (which displays the lock screen) the led stops flashing which is silly as you can easily press the home key in your pocket.
Is there anyway to leave the led light flashing until you swipe & unlock the phone, or to disable waking up the phone by pressing the home key.
i think Led always stop flashing after the screen comes on. This was also on my nexus. didn't com across something to keep it flashing while the screen comes on.
Anyways i don't like the led location, i never see it.

Agree Stupid place to put it, but at least it has one unlike LG & Samsung phones. hope it is possible to stop the phone from waking by pressing the home key though.
I want programmable notification lights like the X1 had.
My X1 still works, but it lacks any decent software to make it work well.
I love it! I ordered a PDAir case with a cutout for the light so I can see it witout taking it out of the case.
Anyone tried Light Flow app?
I hope we can use the lights of the buttons under the screen as notifications too

Would be very nice to have the option for the 2 lights in between the 3 front buttons to flash with notifications aswell.

This was exactly what i was thinking of, it would be great.
That would be BackLight Notification (BLN) it exists for samsung phones that doesn't have a LED.
But it needs a modified kernel to work. So we have to wait for SE to unlock the bootloader and someone to adapt the kernel for bln to work.
It's possible in a cyannogen mod rom under led setting... we'll have to wait for custom roms to use it that way..

At 3:00 Minutes.
has anyone found a way to make the 2 LED lights work for notifications?
Any news on this topic? Will it be possible without rooting the device?
Would be perfect if I can use the front-leds of the device for notifications.

Touch keys NEVER turn off (even when the phone is off)

My touch keys (soft keys) never turn off. Even when the phone is off. When the screen is on they work as they should, meaning that they do turn off completely after not touching the screen for a while, but as soon as the screen turns off, the buttons turn on, and not full brightness but dim. This happened when i started deleting bloatware, but i have already installed different roms and same problem happens. What can i do? Are there any drivers that i should check for the backlight of these buttons?? PLEASE HELP!!!!!
Do you have a text message everytime you see em light up? You might have BLN on... What kernel u running?

Thats what i was hoping for, but my noticifications are clean. I even went back to stock ROM and its still the same. the kernel im running is 2.6.35.11

Sorry about that. I already did, but since the developers are always hanging around here i thought i would get luckier.

Check your display settings. There are options for the soft button lights including "always on."
Even when i put the setting for always off, they would stay off when im working on the phone, but i soon as i turn of the screen the touch keys come on and stay on in a very low dim.
is there any piece of code i can flash to force the touch keys to turn off?
This is for development only.not Q&A or any general.mod please move
From a glaxay better than yours.
Has anyone figured this out? Same thing is happening to me and it's annoying.
It's probably your imagination. The brightness from the screen cancels out light (the light that actually is reflecting off the buttons, not coming from the buttons) coming from the buttons when they are "off" as you use the screen and instantly or slowly come into vision as you turn the screen off. When you turn the screen off, there is no light to cancel out the light (sun's rays) coming from the buttons and you can see them. To test, go into a room with no light at all and turn the phone off. If the dim light from buttons are no longer visible, then it was just your imagination.
You dug this out the grave
Me? I just tought I'd put my thoughts and observations out there and help the guy. I didn't dig up any thread if you are talking to me.

Thats how i knew the lights were staying on, cus when i went to sleep i noticed the lights were still on. This is not visible if there's other light sources around you because the buttons light up very dim. You only notice in a completely dark room.
Did you change your settings? If that didnt work, try taking it to a tmo store.

[Q] Keys not lighting up!

Hi All!
Just got my OneX yesterday.
All was great until nightfall came and I've noticed that the keys aren't lighting up.
The light sensor works fine, and when I plug the charger the buttons light up, but when I unplug the phone, even in a very dark room - no light...
I saw there were a few posts on this subject before but with no conclusion.
Anyone else encountered this / knows what to do?
Thanks
Eyna
I find this only happens when the battery drops below a level and Powersave kicks in? How charged was the battery?
It happens at all levels.
When i go to *#*#3424*#* and do Led test it sometimes works qnd sometimes dont, so its not lamp issue.
Any ideas?
Do tour buttons light up every time you cover thé light sensor (the same way the brightness is reduced)?or is it inconsistent?
Anyone?

Try texting yourself?
I'm fairly sure the leds light up when you receive an SMS or something.
Texting didn't work...
I know the led works, its just that it doesn't work systematically. I can be in a pitch dark room and not have the buttons light up, and I can be in a dimmed light room and have them lit.
My questions is if you guys have the same issue, or does your buttons light up every time its dark?
Appreciate all you help!

I'm running a custom ROM so the LEDs behave differently anyway. Can't remember what they were like on Stock (didn't run stock for very long)
