It's probably already known by everyone that this phone packs an RG notification light (damn you, ZTE!) What's more, blinking seems to be fixed to solid and slow blinking, and it can only display RED , ORANGE and GREEN.
But, at least on ResurrectionRemix, there seems to be a way to turn on the two LEDs that we actually have with the console, and with a desired brightness:
su
echo 255 >/sys/class/leds/red/brightness
255 is the maximum brightness, but it ranges from 0 to 255.
Also, we can do a very nice shade of yellow using:
echo 255 >/sys/class/leds/green/brightness
echo 64 >/sys/class/leds/red/brightness
There are also a bunch of other parameters inside, but brightness is the only one I tested so far. I think we could use this to control the LEDs via a root-enabled app like LightFlow. Is it possible? It would improve a lot the LED quality.
Yellow would be nice. Maybe if you contact the Appflow dev he could make it work. However i'm not sure I want to install an app just to add 1 color

not just colors, in theory... Blinking speed is theoretically changeable, but it is somehow hard-coded and only blinks slowly for some reason. I'm not even sure if it can be just solid when triggered by a notification
There are a bunch of files inside the red and green led folders, and I guess they are what controls the LEDs flashing speed and all. I say "guess" because maybe they are simply ignored and the blinking speed is hard-coded. But whatever the case is, it seems possible to at least turn the LEDs on via shell scripts

I found it extremely disappointing that ZTE gave us only RG lights on the non-Chinese version (I heard the Chinese version has RGB?). For diodes so cheap, I am only led to believe it must have been a manufacturing error on their part. Don't get me wrong, we get more than enough for the price and specs of this beast of a device, but how hard could it be to get RGB LEDs on this device? I really miss multicolour notification lights. This green-red-orange thing gets boring rather quickly.

I really miss the RGB led too. I never know when my notification is important or not.

Yeah, bro. Coming from a One M8 with the same RG lights (used for about 2 years, previously a Nexus 5 which was RGB), you would understand

I've seen LED power indicator mentioned in a few reviews, but couldn't find it on photos. And I don't have Prime yet, only original TF.
So, is there really a power indicator on the power button on the tablet itself?
Also, if it IS there, I have a suggestion. There's an app Missed Message Flasher on market, which flashes LED or hardware button highlight on my phone (which don't have LED) when you got a new notification. Why don't someone make similar app for TF Prime? So with any new notifications it would flash even if screen is off.
I've found myself pressing power button just to check if I got a new messages in IM or a new email quite a lot during everyday use. Would be very useful just to look on the tablet and see if anything require my attention (new notifications) by flashing LED. Hope it's not too dim for that purpose, and power consumption should be miniscule. Yeah I know it's playing a sound when I got something new, but this isn't so convenient and I could be absent at the time when new message appears. Flashing or pulsating LED would be quiet and nice.
Maybe not as app, but as a part of custom ROM - I suspect this functionality would require root.
Because it's in such a weird place you would never check to see the color of the light

Its so small and located in such a way you would have to be looking directly at, its probably not worth it.
Well, in very bright conditions - yes... But in not-so-bright-usual-geek-dungeon even blinking reflection on the table or wall is enough. Again, I don't (yet) have one to test the brightness myself, so this is only a speculation

As others have said, the light is too small, and in a place that the odds of having it in your line of sight would be minimal. You would only have a 25% chance that the top edge of the unit would be in line of sight. Good idea, really, but it plain wouldn't work well enough to be worth it.
BTW, it IS on the power button itself, which leads ME to a question. How is everyone's power button? Mine is stiff as a day old dead dog, and I find myself squashing, pushing, pushing again to get the unit out of sleep mode. My OG Transformers (all 3 of them, have a nice springy detent of perhaps 1/32" - 1/64" (damn America for never adapting the Metric System! I don't know my milimeters from my water meter) The new button is just a mush,, with no noticeable travel)
Ive seen something that ll make a little envelope bounce around on your screen,
though im not sure how battery intense this is (then again this thing has a mamoth batterylife so I wouldnt care!)
This is one reason I still sport my Nexus One which is my main messaging device. I love the RGB glowing trackball which my co-workers all call the glowing eye of mordor.
Not sure why this feature is so overlooked. I guess as more feature phone users upgrade they don't know what they are missing.

Okay then Well, at least it's clear that it _does_ have LED power indicator. Too bad that new button is stiff also. Not a deal-breaker, ofc, but I'd be pressing it quite a lot during use.

^^ this. It is tiny and only in the dark could you see it and only if the tablet has it's edge turned towards you. In reality, it is 100% worthless and I am surprised it is even there.
So I pre-ordered last night at my local at&t store. I am excited as before I went to my at&t store I passed by best buy to hold the dummy model they have. Its big but I was still able to thumb the other side of the device with one hand. I also played with the samsung player which has a 5" screen and runs android but I guess thats just suppose to be an mp3 player, either way it looked similar to the note and it looked great. I can imagine how good the note's display will look.
The only thing right now that is bugging me a little is getting by with no led notification. Can you guys suggest how to get over that little led light that will no longer be on the note? Or how you guys with devices with no led lights are coping?
there is a app that you can get and its free called no led.. My wife had the same issue as she was used to a led light and when she got her samsung she missed it.. works well
But that requires your screen to turn on so basically killing the battery right? I know some samsung devices have that bln mod but not sure how well that works and if its even compatible with the lte note. Any led camera flash apps maybe?
no it puts a small icon that lights up on your screen and bounces around. the rest of your screen is dark.
Camera flash? For notifications? Seems to me that would kill that battery way faster than 64 pixels floating around the screen . . .

What does it really mean to "turn on the screen" for the Samsung AMOLED displays? LCD-based displays need a backlight, even when displaying a single pixel. But turning on just a few LED pixels on a Samsung AMOLED display is probably a very low power operation, since only active pixels should need to be powered, and since there is no backlight.
I haven't had an LED notification for years. And I am thankful that I don't. I remember on BB when I had the LED notification, I was constantly looking at my phone to see if the light was beeping. Without it, I'm so much less obsessed with seeing if I have that stupid blinking light.
@bkeaver - I thought it required the screen to be on
@LiquidArrogance - I've seen the iphone do it like that with a case
@vaxheadroom - Then I definitely am not sure the difference between lcd and AMOLED displays
@kiltedthrower - I'm still obsessed no thanks to the blackberry days
here is a link to the app.... should give you a idea of how it works and what it looks like

Once a kernel is developed that supports bln which I imagine will be fairly quickly, it will be available. And it works very well, I use it on my captivate all you have to do is install the bln supporting kernel, download the app, set up what apps turn on the leds and you're done.

Is it a strain on battery at all? Or does noled work better in regards to battery life?
Anyone tried this yet? I gave it a go, not really sure what to expect. Installed fine, both the front and back lights kept blinking green until I swiped down the notification bar to clear them, even though I didn't have any notifications. I was messing around with the settings, and it is able to recognize the back light independently, so that's good.
Then I let the screen lock, when I went to unlock it nothing would happen, just stay black, im not sure if it turned off, or the screen was just staying off. Thinking it turned off I tried to boot it up, but nothing would happen. So next I tried to get into bootloader mode, which did work. So from there I went into twrp fixed permissions for a good measure and rebooted fine. Then I promptly uninstalled lightflow, until I get some other input from someone else.
So if you are worried about trying I don't think you should be, just give it a go and let me know your results. Just keep in mind you might have to do something to get it to boot if you have a problem, wasn't really a big deal though.

I sent diagnostic information to the developer last week. His reply didn't sound too hopeful. HTC uses different hardware than most companies when it comes to the led mapping. I hope we will see an update that will provide further support for our device.
I wouldn't count on it, unlike the Nexus's notification light the Droid DNA (and most other HTC Phones) do not have multicolored notification lights. The light can effectively be 3 colors I think, which are red, green, and maybe orange/yellow at most (one of those might not even exist I cant remember) but that's it. Now if you just wanted to map those colors to individual actions I guess that could totally be feasible, but new colors outside of those like blue, purple, white, etc just isn't capable with the hardware in our phones.
It kinda sucks if your into that kinda thing, but what can ya do?
I agree that not having the multi-colored leds that my S3 had is an annoyance, but if LightFlow would just work so I could have dark orange for gmail and green for sms, I could live with that...
Unfortunately, I got the black screen at some point... I think after enabling the back led. And add to that I get the green led and it will not shut off no matter what. Sucks.
I'm starting to think that developer support will never get to an acceptable point for the DNA and I will need to go back...

yeah, when I started messing around with LED's I had problems. So in lightflow I just setup my different notifications like normal, but without the LED, and just use the repeating function instead. Yes, the LED would have been nice, but honestly I used lightflow for the custom repeating notifications and the LED was just an added bonus for me and isn't really necessary.
Up until last night I'd always thought that the Ascend Mate 2 (MT2-L03) had a simple dual color notification LED. That being green and red (the combination of which makes orange or amber). I've always been kind of annoyed by this, since it severely hinders the ability to define multiple custom notification colors like I've been used to with Nexus and Motorola devices amongst others.
Last night while trying to do the official Huawei 'downgrade' to Android 4.3 (Jelly Bean) my phone showed that the notification LED is in fact a tri-color one - indeed it's capable of displaying the color blue! I was sort of taken aback, and this makes me wonder why Huawei wouldn't enable the blue segment of the LED in the kernel itself. I'd love to be able to have an unlimited pallete of possible notification colors like I had with my old Galaxy Nexus.
Just something curious that I wanted to share....

The Dev just said he isn't. lol. And to add to that said that it is unable to pulse. So now its just a blue LED that stays on when your screen is off? hahaha.
Did it not pulse with that boot error? I remember seeing it back when but don't remember if it was solid.

I will check into it in a few. Just got home. Never seen mine do blue. But I didn't bother looking at it while it was doing that. Lol.
Well after trying simple stuff mine doesn't seem to be able to display blue. May be hardware variation too. Or they may have used combo to get the blue effect. Sending Hex did nothing.

It definitely pulsed, as in blinked on and off. Maybe he was referring to full PWM control or something...
Who knows, the only time I've ever seen it light was during a failed attempt at using the Huawei flash back to Jelly Bean.
He also said it wasn't very bright, which I definitely disagree with because it was quite bright - easily as bright as I've ever seen the green and red segments light during normal operation of the handset.

Hi Guys and Gals,
I have a question and I am hoping someone with some electrical/software knowledge can chime in and help me out.
I have an RK3066 based android Mercedes Double din unit and the RED LED from the RGB will not work. Blue and Green work fine it is only Red that does not work.
It used to work fine and then all of a sudden I enter the car one day and it's green, (I use a green and red mix to create orange which is the default Mercedes color)
Yesterday it magicall started working again after having not worked for 2 weeks and today it is gone again.
Green slider works
Blue slider works
Red slider makes no color changes and if green and blue are all the way down and red is all the way up the lights are off.
Can this be a resistor or it it software based, I know the kernel can control the LEDs and so on but I am leaning towards hardware related. Maybe a broken SMD resistor these Chinese units are so poorly designed.
Anyways if anyone has some info, it will be greatly appreciated.
God Bless
Same thing here....blue and green work but not red. Stopped working...came back...then went out again. It started after updating in march. I had an older version and wanted the standby timer. RK3066 800x480 KLD unit. I've tried reverting the mcu. Switched to the newest mcu. Reflashed rom. Which actually controls the rgb's?
So far from what I can tell is that the GPIO pin goes to the led resistor then to the led itself and I believe it is controlled via a voltage difference. for example 3v red 3.15 blue, 3.25 green (not actual figures)
What is confusing is that it came back for me then went out again, the dash is extremely hard to pull apart for the Mercedes, not to mention I have a full blown system in here and will have to remove quite a bit of product before getting to the headunit. I was hoping someone with higher software and hardware knowledge would chime in, but it seems like we are on our own. A lot of people on these boards will says "open it and try on your own" I am not sure but I believe that it is 1 resistor for all three colors, unless it is 3 individul leds which would require 3 resistors.
Mine also went out in March (I made no Rom or MCU changes prior to it going out) which is odd then it came back in april, can some software based date cause it to not functions? or can it be that just the red led is failing (defective).
I doubt that it is a resistor since the other two colors work fine and from what i suspect it should be 1 led (RGB) and 1 resistor for the (RGB) led.
Hopefully someone will let us know if there is a remote possiblity that it could be software based, if I was 100% certain that it is hardware based I will and would have already pulled out the unit.
Sounds to me like an intermittent hardware issue - a bad connection somewhere. More likely to be on a connector than a bad PC board trace or cold solder joint.

Do you know if the unit is individual LEDs or is it one rgb led
If it is one led then it should have 1 resistor per led and in which case none of the colors should work.
Could it possibly be kernel based or the rk3088 board/chip itself?
I will pull mine out tuesday night and take a look at the leds to see what the are and get some pics. I ordered a rk3188 SoM and will also be changing over to that rom.
Awesome, please keep me posted. I'm gonna try a few things software wise.
Well I opened it up and almost didn't get it working again. The rgb leds have four legs ground and power for each of the color. My camera sucks so no pics but when changing colors in the elements screen if I select red the blue leds light up. Selecting green does green. Selecting blue goes dark. So I'm really thinking that it's software related.

That happens if you have MCU 2.55 with the sound enhancement MCU version 2.22 works correctly.
if your headunit is still open, is there anyway you can send me the picture of the board and resistors, even if it a horrible picture, its still better than nothing
thanks
Sorry didn't save them. There weren't resistors next to each led but there was a group of them on the other side of each board so a bit of tracing would need to be done to track each one down. For the mcu my unit is KLD and i've tried every version listed here http://forum.xda-developers.com/showpost.php?p=61291848&postcount=14139 and none changed the way the elements act
