Trackpad Notification Light

I was taking a quick look at the leds in the G2.
When i look at the jogball-backlight in regards to the trackpad light, I am unable to change the color. It retains the following value.
# cat color
color : invalid length​I tried to echo "0 255 255" into that, and still see the same message when I cat it. Any ideas?
Also, I can cat 255 into the brightness with no effect. I see the value when I cat brightness, but the light is still off. Looks like you have to trigger it? When sleeping the display and forcing the notification light, the brightness gets set back to 0 after it's flash.
Also the jogball-backlight directory contains:
- uevent
l- subsystem
l- devices
- power/wakeup
- brightness
- max_brightness
- trigger
- color​
Also, check this out.
#cat trigger
[none] rfkill0 battery-charging-or-full battery-charging battery-full usb-online ac-online mmc0 mmc1 mmc2​

You tried this after soft root, correct?
Hahhahha my mistake nevermind...

Where is the trackball light? Is it next to the earpiece like every other LED light on most HTC phones?

It has a touchpad light like the nexus and a battery notify light next the speaker. Currently, the trackpad flashing during an incoming call and the led light by the earpiece flashes during low battery or solid while charging. No flashing anything for notifications such as messages/email/ or reminders which sucks obviously. No apps change this currently without root. I guess this was the concern and the color obviously.

Tweetdeck makes the led flash when new post appear

When I have a new text message, with Chomp, the trackpad flashes intermittently as long as it goes unchecked.

Well that's good news I look a bit harder for 3rd party apps that can make notifications without root and see. Plus, there is a trackpad light app that requires root but let's you change colors and it creates notifications for email/sms/mms/ and reminders.

Have you tried that application yet? Would be interesting to see if it works as the directory structure looks different than what I read about the nexus 1. I was wondering if the 'invalid number' for color was due to no color being available, or just something that we couldn't read/set.
The notification in the earpiece looks to be amber/green versus RGB.

The notification in the earpiece also goes red when battery is low along with amber and green so I think its RGB. I miss that led being used for notifications like on the G1. The trackpad glows slowly for notifications and seems to be only if the screen is off.

If you go to /sys/class/leds you will only see amber and green. On my G1 I see red, green, blue. I think the amber is actually used for the red. I think it would be hard to having any blue colors without a blue led setting.

Im assuming none of you guys seen the other two ligths located at the top left of the device on the face? if im not mistaken if you hold it up to the light it shows a purple square bulb below and a blue one above. is the blue one for blutooth? and is the other thing the proximity sensor?

I'm pretty sure both of the other "bulbs" you see are actually both the proximity sensor, on my vibrant there were 3 things, one was the ambient light sensor and the other 2 were the proximity sensors. I guess its an emitter and reciever.

Hey, I just got the G2 and I am also gravely missing the LED notifications from the G1. I installed handcent, and have gotten the trackpad outline to blink, but the blinking is so infrequent and limited to white. There must be a way to toggle the charging indicator LED's. I've tried the app "Blinker" with no satisfaction. Any help would be greatly appreciated!

not getting the notifications on gmail, or handcent or anything. This is a deal-breaker for me. I may steal my nexus back from my wife and leave her with the G2 if one of you smart guys cant figure this out!

That's because the trackpad does the notifications. Not the other lights nor will they ever work for notifications... get the apps that add reminders and you'll be fine. Quit crying...

Lmao @ quit crying ! But really.. Am I the only one who likes the fact that I can see when I have a notification while my phone is charging? I think it was a good idea though to seperate them. Any dittos?

What is this reminder you are talking about? I don't see any reminder in the sdk. Also, I would be on board with finding alternate apps that use this reminder instead if the Gmail app used it. No notification on gmail blows, I'm sorry!
Also, I heard chomp shows the led notification, but I tried it out and it doesn't how about being a little more constructive and offering alternatives.

No its not a built in option. Nor would it be in the sdk... there a few third party apps that add the ability. Here's what I use: gmail notifier/ sms notifier/ and calendar notifier. They are all free and available in the market. They work very well and make up for lack of traditional led. The trackball flashes too only in white and fades on and off slowly.

When the N1 came out, all we had was white notifications from the trackball. It took some time but devs eventually figured out how to get diverse colored notifications from the trackball, and from the charge LED.
Relax and be patient, surely the G2 will follow the same path. It just came out.

Notif blue led on froyo

So i have been waiting forever to get blue led or any other colors to use with missed calls or sms. sms pop up (app) or missed call (app) will now change your led to only blue. no other color works that i tried but atleast its one more.

Handcent will make any color but red flash the led blue, I don't think it would do anything but red before

emails are red...(gmail & vm)

Handcent only works for red and blue (I have it set to red), My Nimbuzz IM is blue, and my Kik is a purpleish color but u have to set it on green from the notifications setting so it can work.. I'm currently trying to get a new color for my YouMail app...

Omg another thread about this.
I thought magenta worked?
Sent from my SPH-D700 using Tapatalk

The epic only has a red and blue led...no green. So the only colors your going to get will be...
wait for it...red...and....blue
And as stated above, magenta should work since red and blue makes magenta...i couldn't get that to work in 2.1, I'll have to try it now that I'm on froyo.

As far as I know, there's only red, blue and violet (red and blue) led colors. Too bad they didn't put a green one in there. That way you could make a hell of a lot more color combinations with rgb.
The only time I've seen violet is when the phone is charged and the led is blue. Then someone sent you an email or text. With the screen off, unplug the cable and for a brief moment the led is violet.

Ive noticed that on froyo, i get red for email and texts, blue for twitter and purple for im apps

I see a lot of people talking about no green this and no green that. Please point out where I said there's green?.. All I said was to get my Kik messaging app to flash magenta I have to select the green option. But yes those three colors is all I get too....

handscent doesn't do a damn thing with the LED for my epic It doesnt flash, it doesnt even come on when I get a message

Thats strange. I didn't try to change any of my LED stuff like I did on my old mytouch and it still gives me the blinking LED

The main reason is to explain why we are limited to only those three colors. to get more than a few colors, we must have an RGB(red green blue) LED, (which the Epic does not)without one of those, our color options are drastically limited.
Although that is good to know about Kik if I ever try it out.

the only way you will see our led is with the screen off for missed alerts. so if you are using an app and it has a test notif option you push that then turn the screen off and you will see the led

How to set notification led color?

I noticed (unless it was my imagination) 2 different colors for my notification led (which I was pleasantly surprised to find), Gmail is like a light blue, and I think it was fb that was regular blue, so is there an app to set the led color for each app?
Or at least see all the colors it can display?

You can use LightFlow which allows you to control the notifications (light, sound, vibration) for a ridiculous amount of apps. Works perfectly on the Nexus 10, I've used it on my Galaxy Nexus forever. It's a phenomenal app. That's the lite version, there's also a pay version which unlocks more features.

+1 for lightflow, I use it on my phone its great. Trying it for my N10

I'm pretty sure some apps have built in customization for the led color, I've seen it in the facebook and facebook messenger app.

It works very well. Prior to configuring lightflow notifications were not illuminating the LED. After setting up lightflow all is as it should be.

I looked in the Facebook settings but all it had was a toggle to enable notification light, no to change the color.

lol.. well I had found this app before starting this thread, however it seemed like it was messed up because it kept showing a light when I had no notifications. Turns out it was "No signal," and after disabling everything in Light Flow, I can test the led for colors.
I suppose you cannot use any other apps that Light Flow doesn't have? for example Facebook or Google Voice? I don't see any way to add an app. oh well.

Are you using the lite version. Facebook and GV are there for me on the paid version

You can't add programs but the paid version has like over 300 different apps I think. Well worth the dollar or two. I use it for Google Voice on both my N10 and GNex and it works perfectly. If it's not there it's likely due to being the lite version as mentioned above.

That's odd, my phone doesn't even have led notifications support and it shows it to me in the options though lol.

I've noticed the following:
White - Gmail/Gtalk
Green - Yelp, Flight Track
Blue - Facebook
Red - Google+
I heard there was a Purple, but so far I haven't been able to trigger it.

Craigsnotifica goes purple. (Edit: On my S3) Try that.

If you couldn't tweak the color led light for Facebook, go to Setting -> Notifications -> Light

If you're willing to root and flash a custom ROM, many feature the ability to control led and set custom colors on a per-app basis. From personal experience, I know that the AOKP ROM by Task650 and Ktoonsez has an awesome interface for doing so.

Viber LED Color

What's the default color of the LED indicator when you have a new message in viber? Mine's yellow. Isn't it should be blue? Thanks

Not sure about what color it should be for that app since I don't use it, but if you want to change the color try downloading Light Manager from the market. Allows you to change the color of the LED to basically whatever you want for each app.

Question about notification light

Hello guys, i have a simple question for you.
I had the impression that the led notification light for missed calls (top of the screen) is blue. I never payed attention. But today i noticed that the missed call notification light is green, like the fb messenger one.
Is this the right color or something is mixed up? Thanks in advance.

The light on my phone is also different, so I don't think it should be the same color all the time.

There are different color notifications for different apps. For Facebook Messenger is green, for sms is blue etc.
I had the impression that it's also blue for missed calls but i noticed today that is green and i want to know if its the same for the other owners...

I used to like my old Blackberrys bcuz they had apps that let you adjust the LED colors and blink speeds with various apps.

by default its diffrent colors for diffrent apps (most the time). My wife's lights up purple for some game she plays lol. it sucks you cant really customize them through the settings but I've used Light Flow (Play Store) on my S8 and it works perfectly (atleast for me)
