Just noticed - No notification LED?

I just realized that this phone doesn't do anything visual when you have notifications, although when my battery got full the screen turned on briefly and made a noise. When I unlocked the phone I saw the "Your battery is fully charged. Unplug it now." prompt.
Does the screen normally turn on briefly for all notifications, or was this an exception? Is there some other visual notification indicator?
I'm only asking because this just seems alien to me, to have a phone that does not blink. Truth be told, I hated it when my G1 would blink various colors at me.

I will kinda miss this but at the same time it won't nag me like my girlfriend.

I know a few people have mentioned they are working on trying to use the soft key back lights for notification but not sure if anything will happen anytime soon. You can use sms popup that turns the screen on.

It is a little unusual, but change can be a good thing. The softkey light mod could be a good first step in the modding of the Galaxy S. I know it has me wanting to try it and get into coding/modding.
Plus, having to turn your screen on to see if you have notifications lets you enjoy that beautiful, vibrant (pun definitely intended) screen!

I think the easiest and pretty efficient way to go about it is like this...
The Super AMOLED wastes 0 energy when displaying blacks...then have a few blinking red pixels light up when there is a notification...

This should theoretically waste around the same energy as a real blinking notification light...

i need that on my phone asap lol

Wow! Super idea
Just make sure the icons are a little better looking, though

That was just to show off the idea in concept (I used the default photoshop symbols)..Icons can probably be improved but for highest battery saving probably best to stick to 1 color with the minimum pixel use as possible..

Sounds like an awesome idea, would LOVE to see something like this. I just picked one up, but will probably on the fence for the next 14 days haha. This is definitely a step towards me keeping it

Just realized there is also no music widget. Lame. Anyone know if Eliot Stocker's will work?

There's no music widget, but you do have music controls in the notif. pull down. I've been wanting that for a long time.

gigantic picture:
make it happen.

I wouldn't use the blue...OLED's blue deteriorate the fastest...not to mention the point of them being small was to conserve energy...
if you want to make it big it has to be in the most efficient form possible...
of course we can always have the user choose his notification picture...but ideally you'd want to use RED with minimum pixels as possible
Edit: Ok, it looks like someone did the Color saving efficiency proof for me on the Nexas One..see IT HAS TO BE RED..for best battery life....you pretty much use 2x less energy using RED over Blue
http://jsharkey.org/blog/2010/07/01/android-surfaceflinger-tricks-for-fun-and-profit/

Here is an example of what a good middle approach would be (for saving battery energy)

well, we just need to know how LONG it takes for the led's to deteriorate, cause we usually have these phones for at most 2 years, and we have to figure out how long the leds will last, i'm guessing they would for sure, last at least 4 years, i wouldn't say using blue is an issue, but you are right that red does use the least amount of energy, but again, we're gonna have to see how much energy these notifications even use on a real-life basis. the best thing would be to allow people to make their own notification images, this way we would have many beautiful notification images to choose from. but i DID exaggerate my notification though to show the higher extreme of a notification if battery life wasn't an issue.

The phones come with Extra blue...but since blue deteriorates fastest and uses up most of the energy compared to other colors, it would make sense t avoid it if possible...
Ideally I agree it is best to let the user choose their own background while making low energy backgrounds available with information on about how much energy each background takes up on estimate...

Here are the deterioration times for OLED:
Red – 28 cd/A and >100,000 hrs to ½ luminance
Green – 67 cd/A and > 200,000 hrs to ½ luminance
Blue – 10cd/A and >50,000 hrs to ½ luminance

so if the screen was on 24/7 for almost 6 years, your blue LEDs would be half as bright

But I like blue
I like all the ideas so far. I think making it customizable (or at least just not limited) would be good, there are those people who have to show off and will just need a new phone in a year any way, so they should be able to have a crazy notification (although you could have a large slow pulsing notification as well Maybe for if you are at a desk so it will be right in front of you and catch your eye quick).
I would like to point out though, are those the "Spec" numbers or the conservative numbers? Lots of reasons those number won't pan out usually, but still, if it was a blinking notification it would still probably go for at least 5 years straight, and at that point you obviously don't need a phone so why do you have blinking notifications?

Omnia 7 - strange vertical lines on display

Hello,
I have noticed when I look to my display in more detail I can see strange vertical lines through it. It is not very visible but I can see it better when there is white color for example in mail application, or if I setup blue color for lock screen. I wonder if it's just caused by AMOLED technology or my HW is not ok. Is it same on your devices?
Thanks

what colour are the vertical lines? samsungs OLED screens have pentile technology which kinda sucks in my opinion. basicaly it simplifys the pixel structure quite a lot so that it has the same number if pixels but rather than each one being split into a red, blue, green section they have 2 parts each alternating between red green and blue green. i think advantages are that this makes the screen brighter and colours stronger but it also reduces sharpness and seems to make the pixels more visible. i might be wrong for your case but I didnt realise this when i got the phone. still would choose it for the amazing blacks, just a shame they done have normal pixel structure.
hope that helps

Thanks. But I think it's not pentile technology. It looks like tiny straight scratches more visible on top part of the display especially visible on bright color,s for example when I use green for lock screen. I will return it to my seller and hopefully they will fix it or give me a new one.

I noticed it on my Focus, as did Engadget in their Nexus S review:
http://www.engadget.com/2010/12/10/nexus-s-review/
We did see some strange issues with the display -- while it does look handsome in most settings, we noticed some troubling inconsistencies in the panel against certain colors or tones. It was particularly pronounced on solid gray backgrounds (as you can see above). We're not sure the cause of the problem (or if it was simply an issue with the device we had), but it was somewhat troubling.

Can't decide which bothers me more though, the lines or the fact that the screen dynamically dims itself based the amount of white pixels that are displayed on screen.

I can't see those in my omnia, maybe it's only present in some of the panels?

It was quite visible in Game hub mostly on top part of the display. Or try to setup your lock screen to green.

I've noticed this on mine too. I'm wondering if it's just a bit of image retention from the live tiles on the home screen, much like you get on plasma screens. I've got a photo frame app which I'm using as a screen saver for a couple of mins each day to 'clean' the screen.
It may do nothing, but it's worth a try

cant say i can see any lines in the game hub but the green really seems to make the pixels more visible on the white 'games' writing at the top

My Guess would be that this too is due to the PenTile Matrix used by Samsungs Super AMOLED Screens. As the green occurs more often but only at half the size this might lead to this effect:
http://en.wikipedia.org/wiki/File:Nexus_one_screen_microscope.jpg
Sometimes I'm tempted to dub the Display a Super Lame-OLED but only until I see the colors next to a non OLED Display.

That's interesting. My problem looked like those tiny green vertical lines on your picture, but mine had grey colour and were very visible on top part of the display, in the center I could barely notice them. The other thing is that I should see them very close to each other but in my case they were 2-3 milimeters far away from each other, which convinced me that my HW is broken. Also when I showed it to the seller he advised me to send it back for repair.

[REQ] Moto X notification screen

Hi guys, I am pretty sure, I am not the only one, that would want this feature on their Nexus4.
I am currently using the Dash clock widget on my lockscreen, but to be honest a simple minimal notification screen would be much more convenient.

Thats the thing, its not daydream, it triggers when you pick up the device, and it shows you the time and notifications.
I know it won't look as good on non Amoled screens, but still.
http://youtu.be/lbGmfk8yaZU?t=2m25s <- You can see how it works here (it's the only video i can find right now)

This will drain your battery. The Moto X has an AMOLED screen which means that each pixel produces it's own light and can be turned on/off independently of the rest.
The Nexus 4 has a LCD screen. LCD screens have one large backlight. Each pixel is actually a shutter that opens and closes letting light through or not. Even if one pixel needs to be illuminated then the whole backlight has to turn on. this uses WAY more battery than an AMOLED which only has to turn on that single pixel.

Just saw the video. I wanna try this as-well .

Its only going to drain your battery as much as a normal lock screen would. Good logic. Battery drain depends on brightness on the nexus.

With the Moto X the screen turns on when you get a notification. NBD on the Moto X because you're only turning on a few pixels, it's not using that much power. If this happened on the N4 then it would be a problem because you're turning on the whole screen which would suck power down very quickly.

It would drain more battery. His logic makes complete sense. As of right now, we have a notification light that lets us know about pending notifications, this example here is what the moto X has in exchange.
In his description of how each screen works, the notification and time on the moto x would use significantly less battery than that on the nexus 4 because the N4 would have the entire screen on, while the moto x (while displaying the notifications) would only light up the pixels necessary to show us the notifications.

I'm sure there's an option to turn it on when you want to, with the powerbutton. Traditional lock style. Still leaving the notification light active on the n4.

Yeah the instant on thing would be a total battery killer. I would still like the lockscreen just without that though. I really like the look, simple yet capable.

Hoping for a dark theme custom rom

Everything in L is white - bright, blinding, battery wasting white. Dialer, settings, contacts, app drawer. It's too much and doesn't look as elegant as a dark theme.
Hoping that with release of source code, someone will make a dark theme. Will save a lot of battery life as well.

It's true (B vs W, not color). Samsung has optimized the AMOLED displays so well that blacks and whites almost use the same amount of power. Check out the advanced reviews of the S4 panel.

Not quite. On AMOLED displays, when you have a black image, those pixels are actually off (or using an extremely low amount of power). That's one of the benefits of AMOLED - you get very rich and very dark blacks.

I remember this thread awhile back (~ 4 years ago):
(1) At maximum brightness, screen on for 15 minutes
- Default wallpaper will consume about 5% (from 36% down to 31%)
- Pure black wallpaper will consume about 3% (from 30% down to 27%)
(2) At brightness = 20+%, screen on for 15 minutes
- HTC Black wallpaper will consume about 2% (from 26% down to 24%)
- Default wallpaper will consume about 3% (from 23% down to 20%)
I would say at low brightness, 20% - 25%, you will get 1% up to 2% battery saving per 15 minutes, let say 1.5% per 15 minutes. For 1 hour you will get about 6% battery saving.

I have a S4 myself and using a black background doesn't save that much. But yes, there are some savings, but not like what is shown above.

While this is untrue, an even more important point that the op brought up is that the white is UGLY...
look at the app drawer on lollipop! It looks like something circa windows 98! Black is not only sleeker, classier, easier on the eyes, it's easier on the battery. The phone has a freaking amoled screen. Cmon google, utilize it!
And before someone responds with "well with L and project Volta its not necessary...". No matter how efficient the os is it'd be more efficient with a less power consumptive display. So it'd be that much more battery life.
But I mean god, its ugly in white...

Agreed. Too much white. I will us nova anyways I'm sure so that won't be a problem on the launcher stuff, but everywhere else it's too damned bright. Hurts my eyes some times looking at web pages with a white background when im in a very dark room. Even with brightness turned tdown all of the way.

You being ignorant about a topic does not make me a troll he said white wastes battery, if you read his sentence. That's not true in amoled screen. White, black, w.e color waste battery the same in amoled.

I'm sure I will get sick of the white eventually, and make my own black theme. Kind of sad that I haven't done any theming since I got rid of my S4.

You're information is wildly incorrect. I don't know where you're getting that idea from. A single light bulb in your house that is off will use less energy than a light bulb that is on. There is no disputing that. Its a fact of electricity. The same applies to an amoled screen, if the pixel is off, its not using the energy an illuminated pixel is. Plain and simple.
Here's a link, take a read...

Better yet... Google, once upon a time, mentioned theme support. I'd like to see that in Lollipop. That way, whether you want White, Black, Yellow, Green, or even Purple Polka Dots, you can be happy.

I do find it odd that they never added the theme engine. It was always open source. Maybe it posed some security risk or performance issue that they didn't like?

Erm no. Black is significantly more power efficient vs white even on modern AMOLED panels.
Just look at the Note 4 tests on Android Authority. 40% or so more battery life when primarily using black backgrounds versus those with colours.
Also, grey/white shows all of the defects in every AMOLED panel. There'll always be a pink or yellow hue to one side, or if you're unlocky, multiple areas. It's not great.
It's still far easier to ignore than the uneven backlighting that still plagues significant amounts of high end LCD panels these days.

[Q] Screen changes color saturation with brightness.

Hello.
So I've noticed a strange thing while adjusting the screen brightness manually. When you slide the brightness slider it seems like there are individual brightness steps. And each step affects the screen colors differently.
Try it yourself. Like when you slowly slide the brightness slider, focus on the quick toggles background. It changes color slightly with each brightness step. It's very slight and you got to be in a dark room to notice it.
Does it happen on your note 3 too? Is it normal or is mine defective?
Thanks

That's called physics.
Colour is nothing more than light. The less light, the less colour.
Ever noticed how your eyes see everything in black and white in the dark? How the world becomes more monotone whenever there is less less?

I don't mean less colour, but different colour tint with nearly each brightness step, some brightness levels got green tint, some blue and some red. It's hard to explain you have to try it yourself.
It's best noticeable when you download some 3rd party brightness slider adjuster and adjust the brightness while seeing your homescreen and not the almost black notification panel.

I'm using LUX. Right now I'm at -56%(My night setting) and the hue is slightly green. It always makes my blue SwiftKey keyboard a very peculiar sea-green.
Which is still perfectly normal.
You are aware that screens are composed of Red, Green and Blue LEDs?
And that brightness is determined by how much light is emitted by each LED?
Naturally each step will have a slightly different hue.
The three don't blend their light into one, there will always be one of the three LEDs that is the dominant colour.

I too have noticed this. However you will need another smartphone in order to see the difference. This is what I did and this is how I know that there is a slight tint.

Yes, it's normal.
It's more a disadvantage of the Diamond Subpixel configuration. AMOLED isn't at fault, it's the matrix configuration Samsung uses that causes this.
It features size difference in the three colours. As you change the brighness, one colour will overpower the other. The S4 and S5 have the same configuration, as does the Note 4.
