Nexus S 4G: Button Backlight Control - Nexus S Q&A, Help & Troubleshooting

Im wondering if anyone had found a way to disable the capacitive button backlighting similar to the way ledhacks works on the evo.
When I am in low light conditions, the buttons actually end up being brighter than my settings in aldiko.
I have tried a few apps off the market, but nothing seems to be working.

Why, we have a notification LED. I loved BLN for my Vibrant, but I don't see how it is needed here.

That's what they mean.
Notification light within the speaker
Is this what you're referring to?
It only shows up if i have the charger plugged in. Orange when charging and green when charge complete.
Shouldn't this be where your alerts are shown too? I have them set up via this menu:Settings > Display < Notification flash , however i never see any light come on when i have new messages.
Won't work, fascinate had an amoled screen which o believe can turn on individual pixels. The tbolt has an lcd screen which uses a backlight which only lights up the whole screen

He's referring to the backlighting on the soft keys, not the actual touch screen.
This would be great if it's possible. The notification LED is horrible on the TB.
Backlight support, if I remember correctly, has to be built into the kernel... I've only used it with Nero rom on the Samsung Vibrant, never on an HTC device. If you don't like the notification lights on the Thunderbolt, you can download NOLED app from the market... It works well on phones I've tried that have no notification lights like the Nexus S...

Hmmm... never heard of that app. Will check it out. Thanks man!
bumping this hoping its possibile now
now that the source is out
I use an app called "Flashlight Alert" from the market or can be found on the XDA forum.it uses the LED to alert you of email, text, google voice and calls. It's free and doesn't require any additional addons.off that does catch your attention then nothing will. I even used it on my Xoom.
try "missed message flasher" it flashes the backlight whenever you get a new message. it can repeat until you check it or you can set time limits. tons of options and works for all notifications.
If you're rooted there is an app called light flow that works very well. Makes the led notifiers actually serve a purpose.

G2x notifications?

Am I missing something, but I can't find how to enable notifications for missed email or calls. Does this feature exist?
I surprised no one seemed to bothered by lack of led notification... This was the most useful feature in N1

Actually I'm very bothered by it, but knew about it going in. I just don't think any phones are going to have that magic trackball or led notification anymore.
Apparently there's a mod for the Optimus 2x that enables the soft keys at the bottom of the phone to light up as notifications, but it hasn't been ported to the G2X yet.
Well, there might be no dedicated LED, but there are those touch buttons, they should do the trick. As a matter of fact there is an app Touch LED Notifications (BETA) 0.3, but it appears a bit buggy still.
been using touch led beta 0.3 for two days. so far it's workin great!

does the led button app drain your battery life? doesnt that unsleep the phone?
There is also an app in the market called noLED that works awesome.
Noled is great for amoled screens to my knowledge. On amoled you can light up a specific led whereas on LCD you still turn on the entire backlight.
From author's description the app processes notifications only when they are received and the phone is awoken anyway. You can also set timeout after which the less stop flashing (I set it to 3 hours for example.)

The 2x touch LED app has been working for me for almost 2 days now w/no apparent issues.
Touch LED Beta 0.3 working great here! Haven't tested noLED from market but it's meant for AMOLED screens whose black pixels do not consume power. If you use noLED for notifications to display on your LCD screen, it will be like leaving the whole screen on any time you have a message.
Yea 2x touch just pulses your capacitive buttons at the bottom. Its configurable and works great...
I'd rather light up 4 LEDs then my whole backlight.

Started using the Touch LED app, works great. So glad this came along. Hit thanks button rroyter and biturbomunkie.
Hey can one of you tell me your settings on it?? I want to make sure i have it set up correctly.
Its strange im using google voice for text but everytime i receive one the keys dont light up...is this a bug???
Perfect! Just had to change the file extension from txt to apk for some reason. Works good unrooted.
will this stop my entire screen from illuminating when i get a text? all my other android phones did not have their screens turn on when a text comes through unless i had an sms pop up app.
Need a little help with this, when I DL the .apk on my phone, it turns into a .txt file. What am I doin wrong?

LED Notifications (G2X App)

I was using this app for my G2X and thought it might be nice if the developer could make it work for the Sensation, since the notification light is so small. I emailed him to see if it was possible. Any interest in this let the developer know.
It's pretty cool, it lights up the bottom four keys and pulses them when you get a message, so when your screen is off you see the white lights blinking. You can set the times and if you want it to fade in and out.

cool app, i used it on my g2x also... think he can make our notification light blink in different colors? probably only green/red/orange... about to try an app I used on my mt4g to see if it works
I am using Gmail Notifier that I loved on my n1. Unfortunately, you can't select colors of the led (even limited choice that we see on the sensation).
I used the other one on my g2x as well but what I really want is to be able to tell which gmail account an email came from by led notification. Fingers crossed for someone to create something like this.

Will give bln a try once we have root and a kernel that supports it. Looks pretty cool.
Is this still possible now that we have temp root? I would really like this app to work on my sensation.

Found the App for this, it's called Led Me Know. Works perfectly for the led notifications. You have to enable keyboard light up and compatability mode.

What's keyboard light up and what does it do? I have it working on my Sensation, but it's pretty much like the stock notifications, nothing too different other than the frequency.

Do you mean the captive buttons? It doesn't work with compatibility checked. Only thing it does is flash the small led on top.
EDIT: Captive buttons do not light in my case. Do I need to check the box labeled screen on as well?
Ok I forgot to mention you have to have temp root and another app to make this work. Its called Light Flow and the way I made it work was having the paid app. I opened up Light Flow, it asked me for root access, I accepted it, then it asked me to turn on Accessibility. So i did and checked Light Flow. Once I did all that, I went back into the app and went to General Settings, clicked direct mode. Once I did that I scrolled a little further down to "Button back light control" and clicked the option "Control-when the screen is off". After that I went into "Notification" clicked "SMS" and scrolled down to "Button backlight LED" and chose "Solid". Now this is where LED me know comes into play.
I opened LED me know and I made sure "Compatability" was checked. I clicked all the services I want like SMS, Missed Calls, and Gmail. Now I clicked the "Notifications" tab and clicked SMS, I chose LED color to whatever I liked (Green) then chose the LED Frequency to Normal, but you can change that. After all that, checked Keyboard and Keyboard blink. Test it and see if it works.
Wow, I just tried the pre-release of LED me know, http://forum.xda-developers.com/showpost.php?p=13929058&postcount=495 and it asked for root permission. Ever since that, its been working great without having to do all these steps I posted. Can anyone try this method?

Just tried using this version and seems to be working well for me. No need to bother with the steps in the previous post.
So, you don't need paid LightFlow after all?

Dim Softkey brightness? Is it possible?

Is it just me or are the softkeys really bright on the s2?
Well, ive gone on google and tried to find the answer, but seems like there is not a way to possibly reduce the brightness of the softkeys itself.
However, before i give up (i find those softkeys useful, but hard to use at night as its too bright, and turning off the function is difficult to use) I was wondering if its possible without rooting, by using a 3rd party app.
Thanks

That's an interesting idea. The brightness issue made me turn off that light all together (running CM9). I found the light so distracting when using my phone to read a book or something in a dark room at night...
I hope someone chimes in with an idea.
.
Seriously doubt its possible without root.... with root, the only ones i can find just turn them off.. havent seen anything that just dims.
Would definitely say impossible without root, as you need to edit system files to alter hardware functions. I don't believe there is a variable anywhere to edit that though, because I've only ever seen their functions to be off and on with all the phones I've used that have had them. Just my 2 cents, but I'm sure a skilled dev could give you a better opinion.

Darn alright thanks for your posts!
Hopefully a dev could give his $0.02, as i would believe it would make the softkeys more usable throughout the day and night.
i think over time you get use to it. i turned my keys off and i have no problem navigating.

Use the app screen filter. It will allow you to dim the buttons. Not sure if root is needed or not tho.

Didn't work for me either, however, I like the the function of the app for screen brightness.
What rom are you guys on? I'm on AOKP B40 and screen filter worked perfectly. Much easier to dim than with Lux, and back light for keys turned off and on perfectly.

I'm not sure exactly how these specific leds work, but I know with store bought leds, you can use what's called multiplexing which makes them flash faster than your eye can see, but slow enough that it seems as if they are dimmer...not sure if there is a way to lower the speed or if you can even make them flash at all (constantly)
You could also maybe look for a night mode from a third party app to change settings at a certain time

That said.. I wonder if its safe to have a an app to lower voltage/amps to these leds.

[Q] Notification light for Nexus S

Use a kernel with BLN support. It will use your captivate buttons as a makeshift LED notification.'

Does it work well?
Well, sort of. When I had my Vibrant, I could make the buttons really pop out and see them from across the room. With this, if I can see the buttons, then I have a notification. If I don't see any buttons, then it's because the lights are off. It's not as bright and nice as the Vibrant, but at least I can look and see if I have notifications. If you use CM10, there is an option in settings for it, under Advanced.
You can try this app : https://play.google.com/store/apps/details?id=com.led.notify&hl=fr
Works well, no need for specific kernel
