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
i think we'll be okay folks.

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.

Got myself a NEWER Nexus One with SLCD

The first one I ever got was AMOLED which I sold and now I got another Nexus One with a SLCD. Wow, I gotta admit the SLCD is much more clearer than the AMOLED. As for screen response, I feel like it's a little faster. I am running Cyanogen 7.1 RC1 and so far so good.
Was anything else changed on the phone besides the screen? I feel like it's a nice revision from the first Nexus One.

i've always wanted to switch for an SLCD jsut because its clearer, sharper, and my theory is that the screen draws much less power and will be better for battery life for web browsing. i wonder how true that is.

How do you tell if it is AMOLED or SLCD?

Debatable. LCDs draw a constant amount no matter what is displayed. OLED only draws power for pixels lit up.
Originally it was thought that OLEDs would be much less power but in the end it is so close that it is determined by content.

If you go in slickdeals.net and search the forum for "Nexus" they have one for around $249

exactly. i'm so sick of having to watch what type of content i'm looking at. anythign white just murders my battery and i lose 1% every 2 minutes checking stocks and whatnot. an SLCD pulls a constant current no matter the content, and i feel it would be much more manageable.

that's quite lucky for u.
i got mine from amazon ago and just can't stand the blue tint in all the black area, especially when i use dark themes and color most of time to make it easy on my eye and save some battery. That can't be traded towards better text display for me.
sending it back today..

they say Nexus One's AMOLED isn't really WVGA...hope SLCT fixed it.

i have a SLCD, and the colour are fantastic... only the dark, is blue lol
i have comparized my slcd with a desire hd slcd, the my display have much better colour, but the black and the white, are better in the desire hd slcd

Due to pentile matrix, AMOLED effective resolution is 392x653, 2/3 of 480x800 of SLCD.
This is fixed on new SuperAMOLED panels.

I really like AMOLED but i can`t replace my SLCD with AMOLED. Not working...

Black on SGSIII not totally black like SGS I

Hi all SGSIII owner, have you try open your phone in the dark room? Look at the black colour such as in the Settings menu. The black not so black, like the Super AMOLED still lighting not like my previous SGS I. I think, this also drink battery juice faster.

BUMP!
Oh noo!! What is that? I open facebook in my dark bed room last night, when I open a photo from my friend posting, and waiting the photo loading, normally I saw black background and animated circle. But today I noticed total black dots in the background.
I managed plotted the dots in Photoshop, it look like this:

}
Another one issue is dimming.
I test the dimming function from keyboard key-in *#0*#, it not dim like first time I test after I bought the phone. I test the red, green and blue screen still ok, no issue.
What should I do?

I would drink some more juice -

the dots are ink marks that have been known to exist on samoled. According to supercurio, it's a software related problem and should be fixed by his app soon.
back I the sgs day, i didn't have this problem until I flashed cm7, it started happening. I thought my screen had a burn I or dead pixel lol

yeah i feel the exact same thing..im not bothered bout the ink spots, thts hardly noticable....but the blacks not being deep enough, thts very visible in dark lighting with black wallpapers or videos with black backgrounf like when sumthn is loading n just the loading circle n black background or like when test, say the film cast is playing on a black background, the black just seems dark grey....
is this with all sgs3 panels???

the OP is not talking about black spots/blothches man ( his 1st post issue) , hes talking about the depth of black color ...its very dark grey and not deep black like on the s2 and even s1....u can notice it mainly in dim lighting or dark rooms...

Oh I see thanks for the clarification
My Galaxy S II had this issue really really badly, to the point where the keyboard and statusbar were lightly burned into the display. Keyboard was temporary but statusbar burn was permanent.
Galaxy Nexus had it a little better, only one very obvious black spot on one of the on screen navigation buttons (which were always black making it more noticeable)
Galaxy S III hardly has it at all! Was planning on taking it back to the carrier (first phone I've got on contract in 12 months) if I noticed the issue badly, but since it's so little (only a few tiny dots) then I'm going to keep this one

I remember a discussion about this on the Galaxy nexus forum. It's just a limitation of the amoled he technology that they can't make the blacks as deep anymore. Personally I think the higher resolution is worth the sacrifice.

look, the spot/ blotches issue is alright if its not too noticable....so thts fine....
but the blacks not being deep enuf, thts too bad considering s1 n s2 had nice deep blacks...
so basically the Supr amold " HD " screen exclusively has this inability to dispay true blacks ???
P.S: yeah the resolution is great, so much better thn the s2 !! love it !

I use this video to test the black on my note, play it in a totally black room, if you have true black you should not be able to see where the edge of the display and the bezel join.
My note`s black`s are pure black not gray.

If B&W Ultra Power Saving is so efficient, why not use as ALWAYS ON SCREEN feature?

If B&W Ultra Power Saving is so efficient, why not use as ALWAYS ON SCREEN feature?
Samsung introduced Ultra Power Saving mode, that's besides the usual turn-some-radios-off, sets TouchWiz into a low-demand black and white mode, most likely undervolting the SoC in the process. Sammy promises an extra day of standby in this mode.

So how about using the B&W mode for always-on display notifications?
While it's no e-ink display like the back of the YotaPhone, AMOLED can light up subpixels individually, and lower resolution displaying of non-graphic white content with 90% of all subpixels off and SoC at very low voltage could make sense. Especially if the new pixel arrangement is RGBW (I don't think it is for the S5), cause it would mean that of the 4 million sub-pixels, only a small % of 1 million white pixels would be on... we don't need full screen notifications, just part of the screen...
With some further SW tweak, the phone could recognize when is it in pocket (like Moto X) and when on table, so it should only display stuff then the phone is in horizontal position or when you move it etc. With AMOLED advertised for efficiency, wonder why Sammy haven't attempted something like this yet, maybe add an extra low-power chip to handle this little task (and always-on listening).
Thoughts? Potential? Possibilities?

Nobody?

I think the sview cover is probably a better way of doing it. Its so easy to go from low power preview to full functionality

True, but not as always-on notifications. It would just make sense on efficient individually lit AMOLED pixel screens.

It doesn't have to be always on, it could use the gyroscope inside the phone to know when it is being picked up and will then light up the screen.

With some further SW tweak, the phone could recognize when is it in pocket (like Moto X) and when on table, so it should only display stuff then the phone is in horizontal position or when you move it etc. With AMOLED advertised for efficiency, wonder why Sammy haven't attempted something like this yet, maybe add an extra low-power chip to handle this little task (and always-on listening).
Thoughts? Potential? Possibilities?

S800+ already has co processors and DSP they could utilize. Apparently, aosp is more important.
