I have a buddy that has the Nexus 1 and after he installed 2.2, his LED light would change for different notifications like,
Blue LED = Handcent Message
Purple LED = Craiglist Post
etc.....
Is this something that is implemented inside our version of Froyo?? OR is that even possible on our EVO's

Wouldn't the led's have to be physically changed to have the different colors? AFAIK our evos only have a red and a green led installed. I guess its possible I could be wrong but I don't think so....although it has happened before....hehe
Not necessarily. I would imagine it could be changed, unless there are 7 or so LEDs in the N1.
P.S. John Denks sucks.

Thats correct. Evo's only LED colors are amber and green.
Also, I believe these sort of questions belong in the Q&A section. Just a heads up for next time
EDIT: See here for details on LED Swap.

I don't think software or firmware can determine the color of an led....
You only need red,blue, green to make all the colors imaginable...since our phone only has amber and green, then theoretically we can combine those colors to make more...unfortunately, what colors could those be?

theoretically true IF you could realistically vary the intensity of the LEDs, but one LEDs are not generally that readily variable and two, they are most likely connected to digital outputs so they are either Off or On.
Will not work that way. They are individual parts and on the evo the green is angled to the left. And the amber is angled to the right...so even if you could turn them on at the same time they would not be focused to one point to blend into a different color. Give up can't be done! Unless you swap out the leds.
What about varying the duty cycle of the leds, theoretically that whould result in a color blend even though leds are angled.
However, there aren't many colors that could be created by mixing green and amber.

Interesting
On my nexus the led only blinked white, and many people challenged whether or not it can be done, but eventually there was a mod released allowing to choose between any color I wanted to track ball to glow.
But if the LEDs are in different places like stated above then I think it would be more of a challenge.
from what i have noticed with my evo. the way the LED light is set up is: A electric current flows one way to emit a green light, or it flows the opposite way to emit the amber color. This is something I have learned in a circuits class and seems logical that it would work this way. I dont think with this situation having different colored LEDs will work.

Have you tested this? A typical led is a diode where current can only flow one way, and based on the fact that the leds are displaced, it appears that there are 2 leds.
Additionally, even if only one led could be on at one time, alternating the emission while controlling duty cycle could create an effect of mixed color.
Sent from my PC36100 using XDA App
Most likely it's two leds built together. White leds can be made the same way, with a red, green, and blue diode built together. When all three are on, the color will look white.

On CyanogenMod 6 (8/4 nightly build), the LED alternates orange and green for text messages and just orange for email and other notifications.

There are bi-color LEDs that only have 2 leads. Internally they have 2 LEDs wired in an inverse parallel configuration. You apply power one way, green... Apply power the other, yellow.
A better scenario is if the EVO has a tri-color LED (uses 3 leads), which means one set = Red, other set = Green, both sets = Yellow.
Hi!
I have a strange problem with one desire...
After changing the broken lcd screen, the display is very yellowish, everything witch was "white colour", is now yellow...
I have tested 4 lcd-s, changed the rom (multiple ROM-s), but same result...
Strange is even when i try to make color correction with Calibrator (calibrated-signed-42-Universal)... i can change red and green, but changing blue is not working to obtaining "white"...so it remain the same color with values (for blue) from 0 untill 1000.
Is there an another program to make color correction, or is a hardwere fault?
Any ideas?
Thanks
How exactly are you changing the "lcd"
There are two types of screen that the desire can use (depending on your model) amoLED (led!) or SLCD (super lcd). So unless you replace your screen with the correct replacement type for your specific handset your going to have strange issues.
Maybe you should take a very close look at your display, with a magnifying glass or a microscope and check if the blue sub-pixels work at all. It seems as if they don't work and you get amber colors.
I have received the phone with broken display, after power on, it was dark screen no display...so obviously i changed the lcd with the same model, wich is a Samsung (AMOLED i think), P/N: 60H00287-00.
I'm pretty sure it's the correct type of display if anything is being displayed. The problem might be the connection between the mainboard and the screen. Perhaps you've accidentally damaged it when changing the screen? Maybe you should post some pictures of your assembly showing the connection. That might let someone see the problem and suggest a solution.
if you need to understand better the problem i can upload some photos of the Desire...
The assembly is correct, i checked it, i think it`s a micro crack on the mainboard, suffered during the shock, so i will resolder the contacts... i will keep u updated...
meanwhile, i wait other opinions also..
I have found the problem...It was the filter near the lcd connctor...they are 3 filters...for each color...RGB...so after resoldering all of them, and 6 hours of work...it`s working...

I just got my Galaxy nexus (an hour ago), and I'm getting around using it pretty well except for one thing which is annoying me big time.
The screen seems to dim or change its color balance when viewing certain things. Whites are usually dimmed at most times, but when I view other things, the dimness goes away and whites become very radiant.
It seems like the phone is adjusting automatically to things on the screen for the sake of energy saving. How do i disable this!?
Yes, I have my Brightness on manual and set to full. That is not the issue.
okay wow this is getting annoying... Two more issues:
1-The thing won't transfer files while im using windows 7 "the device has either stopped responding or has been disconnected". When using OSX Lion, it isn't even detected.
2-There is chinese text here and there no matter what I do for language settings.
This is my first android phone ever, and I'm not liking the experience so far...
Look, I've tried searching for these two issues, and I did not find any threads with them resolved. Maybe I'm computer illiterate. Maybe I have a very low IQ, but can you just help me resolve these issues IF you know how to resolve them without just going into my thread and be like "Oh look, another noob", and proceed with leaving?
PS: I AM A NOOB.
Protip 1. Read up on amoled technology a little. And then read some of the issues some phones like galaxy s2 had. Your dimming is normal. It sounds like you're just more sensitive to it.
Protip 2. Download the appropriate drivers. In device manager, you want it to say android adb interface when you're phone is plugged in.
Protip 3. Take a chill pill. It is okay to be a noob. It happens. Your attitude comes off as annoying or you're freaking out over nothing. Solving problems take time and we are not sorry xda can solve them instantly for you. Patience, amigo.

You might try turning of Auto Brightness and set it somewhere you feel comfortable... I just decided when I got this phone that I'd make myself get used to the adjustments and it's worked out well.
IMHO the adjustments going from white to black are less noticeable on 4.0.3
As far as the dimming, you have Auto Brightness on. Go to settings, screen and set the brightness to something else.

samsung drivers
for the drivers use this post
http://forum.xda-developers.com/showthread.php?p=20311264
PDAnet installs the drivers for you nice and easy, then you can remove from your phone and pc and the drivers will stay behind.
at this time there is no way to disable the screen dimming function. samsung's other phones have this feature as well, with an option to disable it in settings. its a power saving feature. for whatever reason google did not give any option to turn this on or off. so for now we have to wait if maybe a ROM can disable it.
For OSX you need to download Android file transfer for it to be seen.

Thank you everyone ...Sorry for the attitude earlier.
It seems like I got one of the GNexus phones which have a really good screen (The colors are just mind blowing), its only the dimming thing which is getting in the way. Also, I've tried to update to 4.0.3 and checked out the developer's section of the GNexus forum, but the steps are kind of overwhelming and I'm having my final exams at university right now, so I'll have to wait for a week to just sit back and read everything slowly and correctly.
One more thing, is there a download link to the official 4.0.3 mod ? It seems like everyone here prefers modded images one way or another.
lol. the dimming you are referring to is probably from current draw or a trait inherent to amoled. some people have mentioned they notice "dimming" like on white background browser and you pop up your keyboard. the white will get dimmer or yellower, or black more grayish. this is what you're talking about?

Its the opposite. When you draw the keyboard out, the whites get brighter and stronger. I don't have yellowing on my phone (thank god), but I do have dimming.
top make it simple:
The more the blacks = The brighter/stronger the whites.
Clearly a voltage issue for power consumption's sake. As the phone physically switches of diodes to achieve true blacks, more energy flows to lit diodes and they in turn become brighter.
Isn't there some sort of tweak deep enough to give full power to all diodes at all times regardless of what's on the screen (Full power even if the entire screen is white) ?
Firstly, welcome to Android. Once you get used to it you'll love it. I gave the same problem Windows 7 sometimes usually large video files and need to say that the adb drivers are not required to transfer files to the phone - I don't have them installed and I can still transfer data.
I have to say this is my first amoled device and I haven't noticed any dimming unless I have auto brightness on of course which I understand you don't.

ah yes. you're correct. i had it backwards.
I have the same issue with transferring large amounts of data using Windows 7. Looking for a fix too.
Investing the time to learn how to setup the SDK and using ADB will be well worth it.

Out of the three results I found searching for this topic, I'm glad I checked this thread.
The exact thing I was wondering was:
Is there any way to disable the screen from getting brighter when my keyboard comes up on the screen?
From reading your response, it seems that the screen getting brighter is a result of the design of the screen, suggesting that there is no way to stop it from happening. The only thing I've been able to do to make the screen remain at the brightness I set it is to change the theme of my keyboard to a brighter or lighter color based theme.
I'm using Swiftkey with the Neon keyboard, it looks great and I love it!
I had a Samsung Vibrant previously to the Galaxy Nexus, and there indeed was a "Power Saving Option" in the settings and if I remember correctly that stopped the screen from getting brighter with the keyboard on screen. Has any fix / ability to change this on a stock Galaxy Nexus running JB been found? It's just barely annoying enough for me to notice it, plus I'm a stickler for more battery life and I can feel my battery dying the brighter the screen gets. ( I know this last part may be a mental thing, but still. Haha. )

I've only seen them for the nexus line phones.. Well except for the nexus s.. I think I might of seen a rom somewhere that tweaked the led a little but nothing too drastically. I think it was like green led for notification, flashing red for missed call or something I can't remember

I might be wrong but the led can only change red or green. It was the same with the htc desire.
We need a RGB LED notification light for various colours like in the Nexus or SGS3 or Blackberrys. I don't think we have a RGB one.

Try light flow light it can make the notification led glow in different colors.But in our one x its of no use since our phone has only red and green led.Miss my desire for that feature it can nearly display 5 or 6 colors and i assigned a color for each different type of notification!

No LED is not a very good solution for non AMOLED screens. With LCDs the whole screen lights up, this will drain the battery faster.
HOX only has RED or GREEN
Not to question anyone, but how has it been determined that the HOX ONLY supports red and green, aside from that being all that we've seen it display? I ask mostly out of simply curiosity (if someone has looked at the actual LED, or perhaps seen code proving it), but also because I just don't understand why a manufacturer wouldn't include an RGB LED over two separate LEDs or a bi-color LED. I can't imagine the price would be that different, and the possibilities are endless. No LED is silly, a non-RGB LED is silly. Wish the manufacturers would think these simple things through more.
Still, I've had Samsung phones prior to this, so I'm used to having no LED at all, so even green and red is a big upgrade to me!
Hi
At best you might get three colours, Red, Green, or Orange, i.e. both Red and Green lit, this will give you a yellow/orange color.
However, in order to optimise the circuitry layout, the LED likely only has two connections. To switch between red or green, the voltage is simply reversed. This makes it impossible to have both LEDs on at the same time. I expect this is the case in the HOX, so Red or Green is all you can get.
Regards
Phil

Take a closer look at those LEDs. They won't be changing color at all.
The red and green actually come from different parts behind the mesh.
From this I would gather that there are just2 different LEDs behind there.

would be nice to have both flash at same time or have them blink a certain number of times or have them stay on for a few seconds or something like Morse code...
Is there any app like led me know that can use keys under the screen for notifications? that would make me so happy i have a international model with the default rom
Hey guys, got the phone for a few days.
already got burn ins from whatsapp. the white textbox is two times burned in (keyboard/without)
if u open up a dark grey picture u might see it as well.
just have seen it by an accident when opening "simple gallery", its base backround color was grey, so i found the burn ins.
i am not sure if all displays are affected by the burn ins, i will return mine :/
oh no. can u install aida 64, click on display, whats the panel id.

Are you on MIUI or some custom rom?
If you are on a custom rom, go to display and then to live display and then to colors and from 100% go to 95% to all of them. This happened to tianma panels on Redmi Note 4 too on custom roms.
This also happens to every LG since G4. Low-quality LCD Panels.
There is nothing wrong with your phone , you can rest assured.

but atm the phone is pretty new on the market and we need to wait a little bit

actually it´s image retention, not a burn in. so it´s not good, but it seems to be okay.
i am not able to take a photo, cuz u would need a better camera for it.
i guess it depends on the apps that u use and how often.
if u want to see if u got it as well, you could try to download a simple grey picture.
for me grey/dark grey worked good to check it. then open it in fullscreen. u might see the buttons from the navbar slightly.
i´ve been using whatsapp a lot the last few hours, so i could see the white textbox.
atm i am on RR and i recently found out that u barely get max brightness on autobrightnes maxed out. after using max brightness (manual) it seemed to be better. dunno why may be on max brightnes, the pixel get "reset" better. i don´t know.
all in all. it´s okay for me and i guess if u got it, u can recalibrate it.
I installed aida 64 from playstore but I don´t get any panel info in "display"... where do you guys find that Info about panel manufacturer?
Everything is going to be alright. It's just a low-quality screen, nothing can be done except:
Go to display, live display, color tweak and tweak the colors. From 100% go to 95% and voila, everything is going to be normal. Tinama screens are pretty bad, you can go to the redmi note 4 forum and then look for image retention. There are a lot of topics about that and it seems that only tinama screens are affected.
tl;dr: nothing to be worried about. You probably wont have problems on MIUI because the screen is calibrated

And why should we be forced to use ugly Cold mode? We lose color accuracy just by doing that, along with the screen having an unnatural blue hue which is also bad for the eyes, I want color accuracy not a screen looking like it's frosted
Hi,
i am on "Linageos 15.1" and today i saw that the color of the screen went to dirty. Before i had very good color representation and now it is like gray, no saturation, no big hue.
While rebooting the phone i saw the last Apps i was running. I can see the Statusbar while i am on bootloader-animation.
My phone runs for about 1,5 months and this issue appeared immediately from one second to another.
So there is no solution to get the display working as it should?
So i have to buy a new phone?
I got a replacement device b/c of the image retention. The display manufacturer is not Tianma anymore but Shenchao. The model number stays the same.
