Notification LED distorted?

I am positive that I am being paranoid about this but I thought I'd ask you guys anyway - when you guys use light flow to control the LED - if its a mixed color like, white, orange, cyan - do you see residue of indiviual led colors around the notification light? I mean when I do white I see a tint of green in one corner of the notification area, a bit of yellow, a bit of red but from a distance it looks white. I know white is a mix of all those colors but I just wanted to confirm that the LEDs on my phone arent out of place.

The notification LED isn't uniform; that's normal. It's good enough, you shouldn't bothered by it, as long as you can tell red from orange and the likes.

Thanks for the response!

i see the mixed colors as well for the color white. my nexus one LED did not do this, but i figure it's normal since samsung used RGB to make up the LED. they just must have positioned them differently in such a way that there is slight bleed thru. no big deal to me.

Our Nexus Ones had a large translucent trackball to further mix the colors....

Yep, whatever diffuser they put over the top of the rgb led doesn't mix colors very well at all. I almost miss the Nexus One track ball.

Could be worse, the Nexus S doesn't even have a notification LED.

it will get bad when we're *****ing about phones that didn't holographically project who sent you a text or email. but then again who wants to see your grandma naked?

Notification LED dim on Grey model

Hi,
I got a grey One X last week and while fairly happy with the phone I thought the notification LED was pretty dim. Unless I look at the phone flat on I can't see it is on. I accepted this was to do with the LED being placed within the speaker grill; however a friend got a White version a few days later and the LED on his is about 3 times brighter.
A few videos I have seen show the Grey phone has a very dim light, would post them but can't link unfortunately.

Has anyone else noticed this or is this an issue with my phone?

I think that is simply because with the white casing, the light is able to shine through the white casing itself. Whereas obviously with the darker casing, it is truly confined to the tiny little hole of the earpiece. I do get the feeling that HTC designed the white one first

Yeah maybe, but comparing the two side by side, it looks as though his LED is a different type entirely. Looking at the LED straight on should negate the case colour and in that scenario his white version is still far brighter.
As long as other people think the grey one is dim there is no reason to send mine back.

It was one of the first things I noticed when I held a grey one. So I don't think it is faulty. But just like most things, LEDs do vary from unit to unit in brightness.

i haven't seen a grey one, but with my 2nd white replacement, the charging led was stupidly dim. now im on the 3rd replacement, the same led is much much brighter. leads me to believe it was positioned incorrectly, or just a crap led.
quality control really sucks atm.

[Q] LED Notification light defective??

The other day I noticed that my once stock white colored notification LED was acting strangely. It now is multicolored and seems to have a slight flicker when it goes off. I went through Samsung US support steps, removed apps, then full factory reset. Still same problem. I installed Light Flow and tested all colors. Most work but still with a bit of a flicker. White is not working. It displays in three colors, yellow pink and green/blue? I suppose my LED has broken. Has this happened to anyone else? Is there a solution? Samsung US will not support the repair as it is an international GSM phone.
Thank you.

Yeah white isn't really white, its a combination of three colors. Its normal.. no biggie
Well mine is also like that..

I have had my phone since January and it was always a white notification. My old Nexus One was also always a plain white notification. I am pretty sure thats what stock Android intends it to be. The multicolored just started. Either way Light Flow when set to White should display a white notification but it cannot. I am almost certain my LED is defective. Anyone else?

As proved by Newton:
White light is the effect of combining the visible colors of light in suitable proportions (the same present in solar light).

Ok, so... no help here. Thanks anyway, guys.
I sure wish my LED could be fixed. <head down>

Everything you describe is normal.
You probably just never noticed it before.

I actually did notice it and that is why I have posted here. The notification light is supposed to be white. Not multicolored. I know this phone like the back of my hand. The led has changed.

Mine has been like exactly what you've described on both Nexus' that I've owned.

It's a tri-colored LED (red, green, blue).
It displays different colors by mixing those 3 primary colors.
To get white, it mixes all 3.
The 3 LED's aren't close enough together, so around the edges you'll see the individual colors, but in the center it will appear white.
At certain distances/angles/lighting conditions, it can appear almost fully white.

If you insist that it was pure white before, then somehow you had a white LED and it has transformed into a RGB LED.
I'm pretty sure no Galaxy Nexus's were shipped with a white LED, and certainly not ones that can transform.

AFAIK
The notification LED at the bottom of the phone has always been a 3 color LED. Red, green and blue. To get white it turns on all 3. Other colors are variations on a theme.

Thank you, terryhau.
My notification light does not look like it does in that video. It is now mostly pink with a green hue no the bottom portion and a purple/blue color in the top left hand portion. It DID NOT used to be like this.
I guess I need to post a pic somehow.

Maybe something like an update or .apk has changed the behavior of the LEDs like reduced the output which would explain why you now see all 3 colors instead of white.

I did a full factory reset hoping that may be the case. No luck. This hasn't happened to anyone else?

The video shows that it is not pure white, but a mixture of colors. Kind of hard to see because of the bad camera.

Yes. And in the video it shows what my led looked like about three days ago. It no longer displays that way. Now the three colors are glaringly obvious with a bit of a flicker as it fades out.

I am having the same issue. I have a galaxy nexus from sprint and the play store. the sprint one is perfect. all colors requiring a mix of colors show perfectly like pink, magenta, lime etc. However the play one does not. its almost like its off center so with lime you will see a bit of green and then orange on one side. Pink is slightly pink on one section then almost white every where else. Purple is purple and then has a nice section of blue on one edge.
So my question is those who have replaced your screen is the led attached to it or is it part of the speaker daughter board?

My led is darned close to white (accepting Newton's physical laws etc.). I'm thinking that if yours has changed then perhaps it's damaged, but perhaps your rom settings have (been) changed and your notification colour is now set differently (by default). What rom are you using?
I'm using CM9, which nominally allows me to have notifications in different colours for different apps. I find when I pick colours from the chooser, though I'm meant to have complete control over the colour, in reality I can get white, red, blue, green, and different rotations of rainbows.
Clarification: when I say I can get 'red, blue, and green', I mean properly: I get a solid circle of whichever one of those colours I'm aiming for. But anything else (e.g. yellow, orange, cyan, magenta, lilac, etc.) will be a the chosen colour in a small part of the circle, and an array of all the other colours elsewhere in the rest of the circle.

i can get all those colors too... but only on a portion of the window. white will show green, blue and pink on the side.. but not just around the edges. I think this is what the OP was talking about. I honestly do not think its a software issue as i am running lightflow on both of my nexus's and one is has run cm9 and AOKP witht he same results. It has to be a hardware issue. So if any one can answer this, is the LED attached to the screen or the lower speaker daughter board?

LED notification - different on White/Grey versions?

I'm now on my 3rd unlocked European One X for one reason or another - the white one's LED was just right - I could clearly see from a distance if it was charging or flashing. The two grey ones I've had both had barely visible LEDs, which I can't see when the phone isn't right in front of me or when it's at an angle. Is this a problem with some of the phones in gereral or is it just an issue with the grey model? Cheers.

Your 2 grey phones may have been defective, but in general white surfaces reflect more light than black/grey surfaces. This could have made it appear as though the lights were of differing brightnesses, or just that the white phone reflects more of the led's light.

My grey one is just the same regarding the LED, it's a pixel sized flash as it is shining through one of the "precision" drilled ear speaker holes, so you have to be almost looking directly down on it to see it, certainly in normal lighting conditions.
I expect the white is just a bit more translucent so you see a bigger area of light.
It is one of those silly design decisions that HTC seem to make sometimes! The LED should be behind the glass at the top right where the border is, in the same way the other sits the light sensor. I've always assumed it was last minute rushed job to add an LED, and as after thought they just had to place it where they could that didn't mean reworking the phones design.
Some phones don't have LEDs at all. I'm not sure why a notification LED has fallen out of fashion, I find it really useful, for example I leave my desk to make a drink or see someone or for a comfort break, then arrive back to my desk, a quick look down at my phone I know nothing arrived while I was away and it saves turning the screen on to check.
Regards
Phil

It must be a defect which happens to be on the 2 grey phones then because the difference is huge - one is barely visible and the other I can easily see from across the room (it's probably 30 or so times brighter). Hopefully my 4th One X, which is on its way, will be ok (the white one with the good LED has the wifi problem so that's going back).

Camera flash bulb is now yellow?

I've never dropped this phone on the ground or in water but last night I've noticed the flashlight wasn't as bright as before,so I looked @ the flash and the top flash bulb is blue and the bottom one is yellow. Should I be concerned?

the two colored bulbs are supposed to produce a full spectrum light.
No reason to be concerned unless 1 is dead.

So my issue is normal?

Yes its very normal. The m9 has 2 leds, one white and one yellow.
I wish I stole my HTC M9.
