Make Taskbar Grey?

Is there any way to change the taskbar at the top from black to gray like stock android?

http://forum.xda-developers.com/showthread.php?t=730175
The dark grey it is now is useless, I'd turn it black and spare battery and burn in problems...

Hey thats my morph... The text is still white... And it should have the h symbol... It works though.. What are these burn in and battery problems you talk about?
I don't think it was ever proven a black led uses less power than white and my g1 has had a white bar for almost 2 years and no burn in problems...

G1 was LCD pixels were lit regardless of color displayed.
On an AMOLED screen pixels represent black by turning off. Black cannot be burned in and will not use battery. The symbols could still burn in eventually but fortunately the time is always changing as are the signal bars on tmobile
There is plenty of proof floating around from the nexus one (also amoled) saving battery by having a black theme. I'm not gonna dig it up, it's there. They ran multiple tests on identical phones black saved most then red, I think green and blue were mid and of course white is the worst.

So your saying lcd screens don't have burn in? Or that oled is worse? Not meaning to put words in your mouth... I just enjoy a white/light look..
I still think that is a marketing ploy by apple not to buy oled screens..
I think the phone will be obselete by the time it starts to deteriorate...

LCD does have burn in, the difference is on LCD any color can cause it, so on a g1 making the bar black has no benefit.
I'm not trying to tell you what to like, believe me I love android's ability to let us have this choice/conversation.
Clearly google agrees with you on preferring a white look: first the notification bar, then the market, now maps.
I agree deterioration will probably not be an issue for most, as long as you don't set it to stay awake while charging and leave it in a browser window or something all day every day.

Also, what did apple say about oled? I dint know they had a stance on it. I figured they would be going there soon for either phones or laptops

You think there'd be an easy way to do this.. I don't know why but I'm highly turned off by the black bar. Brings back memories of the WinMo nightmare. Lol

I'll send a message to cloverdale and manup... See if one of them went to change the xml so we can have black font in the status bar...

Actually modern LCD displays do not suffer from burn in. I have had an LCD monitor on my windows computer with the exact same taskbar displayed for months and even years, with zero burn in. I have no idea about OLED though.
What's more, even if LCD did suffer burn in, changing the taskbar to black would then cause the taskbar area to not burn in while the rest of the screen did, leading to a situation where you could still see the spot on the screen where the taskbar resided. That's why a lot of plasma TVs and dvd players have the option of putting grey bars on the side of an image that does not fill the screen, with the idea that the grey is closest to what the rest of the display is showing.
The bottom line is I don't think anyone needs to worry about burning in their LCD screen. This is the Vibrant forum, so we should be concerned only about OLED here. So, does anyone have a real answer about burn in on OLED screens? Wikipedia seems to think so http://en.wikipedia.org/wiki/Organic_LED.

So the life is 5 years at 8 hours a day? Half life is about 30 months... Like I said before... We will probably have a new phone by the time out screen starts to be less "vibrant"

Screen Burn In !!!

edit: *Burn in may not be noticeable at the early stages unless you examine the screen, I used "Screen Test" app from market, please download this or something equivalent, and examine your screen closely before you vote."
So this may not apply to those who just purchased their phone, but for those of you who got your phone around launch time, examine your phone for burn in. Use "Screen Test" from the market, and go through each color, looking for burn in. Oh this is a new addition, I noticed my burn in his worse when the screen is set to the lowest brightness setting. So repeat the test after you dim your screen.
I've had my phone over 2 months, downloaded "screen test" and guess what. The AM/PM up in the notification bar has burned in!
When you download "Screen Test" app, you will notice two things about your screen. Do not be alarmed, the following is normal.
1) Very thin green vertical line along left side of screen
2)Thin gray-shady horizontal bar on top, this is not the notification bar burning in.
What is not normal....BURN IN!
Can't believe the AM/PM is burnt in after 2 months. Shame.
Samsung has to update this by having the time hop around the notification bar instead of staying stationary.
Maybe a dev can work on this?

Got mine on launch day. No burn in.

They really need to change the time and AM/PM stamp from being stationary, they need to make it hop around the notification bar, or something. This is horrible, 2 months and AM/PM is burning in!
I'm sure the signal bars, wifi, and other stuff in notification bar will start to burn in next.
I'm also worried about the battery full message that stays on all night, that will start to burn the screen too.

No burn in here. Got my phone the third week of August.

i always thought leds burned cooler so the idea of burn in never even occured to me on this phone or any other phone for that matter...i doubt a warranty calim would fix it because i think all these vibrants will eventually have burn in...it wouldnt be easy i think to have an animated notification bar, but CM6 does have an option to remove and modify stuff on the notification bar like time and signal, wifi etc.

For making me notice this, I hate you.
I don't always complain, but when I do, I #BlameWes

I have the green line on the left side and the gray bar up top, but no am/pm.
Do you guys leave the display on while it charges?
My display is only on while I use the phone, I got it around release date

Not totally for me, but I can see it faintly coming in. I have had this phone (my third one) for almost 2 months now.

I use beautiful widget works great had since day one in august screen is perfect

I'm kind of curious why an AMOLED screen would get burn-in. There's no backlight, so the only image we see is coming from emitting pixels. Is there a coating on the glass that burns in?

Good question. Could the following be a possibility?
LED's eventually start to die off. Could areas that are always lit, for example the AM/PM is always on, thus those LED's are dying, which makes that area unable to to fully brighten, giving the impression of burning in, since the surrounding LED's are still bright.
That's just a guess on my part.
Also, are you sure Amoled's don't burn in, or is that just a guess/opinion/question on your part?

I can't really vote since I've only had it for a month and a few days, but I don't have any burn in. It's probably because it never disabled orientation flip and I do watch a some kind of video on the phone daily.

Had mine since day one. No burn in. my phone barely makes it to the charger most nights and some it needs an afternoon charge so I definitely use the phone quite a bit.

Damn it. Did screen test. Area where signal bars and time would be are clearly suffering from burn in. Awesome! This, combined with the generally bad software is making me consider selling this and never buying a Samsung phone ever again. (Sad, because their TV's are the best of the bunch.) To be fair, it's only noticeable when you look for it during a white screen and only in that area. Still, really Samsung? I've had this phone for 2 and a half months.

Had my phone for about a month and a half now, ran screen test and am seeing burn in
.

Got my Vibrant the day it launched - July 15th - no burn in, I use it quite a bit, but have the screen timeout after 30 secs.

Surely is burning in. Barely see it, but it is visible.

True Black

So, I stumbled across something really cool (quite) a few minutes ago: apparently our devices really can power a few pixels selectively. In my accidental confirmation of Samsung's claim, I was able to get one of NoLED's notification icons to show on the screen without lighting up the rest of the black area for literally a split second.
Here's how:
1. You will need the app "NoLED" in order to continue. In the NoLED settings, make sure you have the icon for sms activated as well as the proximity sensor. My sms icon is set to a lime green, but I doubt that will affect this "test."
2. Send yourself a text message either from your own phone or from some other sms capable device. If sending it to yourself from your own phone, quickly lock the device using the power button after pushing send.
3. Allow NoLED to start flashing around the icon for sms. Wait roughly 5 seconds for the proximity sensor to activate.
4. For steps 4 and 5, it would be wise to be in a completely dark room to be able to more easily tell the difference between the true black and the lit black. With the proximity sensor now active, place your finger over it. The screen should turn off.
5. Now, upon removing your finger pay close attention to the icon that will appear. The icon will show up a couple of milliseconds before the rest of the screen activates.
6. Repeat steps 4 and 5 if needed to witness the true black.
This is proof that our SAMOLED screens can display true black.
I am not a developer so I have no idea how to act upon this find to, if possible, adjust settings in the our software to allow true black.
If you happen to know someone who is capable of modifying the kernels or ROMs for our devices to allow this behavior, then by all means have them follow the above steps to see the proof.
Though I hope this minor find can give someone the inspiration and/or start place needed to make these adjustments, I realize this is but a pebble in a world of boulders. Therefore, I remain skeptical and strongly advise others not to get your hopes up.
If anything, it is at least nice to see that Samsung wasn't just lying about the capabilities of SAMOLED screens, but also makes one wonder why they don't allow true black from the start.
Now, time to hit the hay.
Goodnight all.

When i power the device off in a dark room, at the end of the power off cycle I get a black screen that isn't black like the other black screens when the phone is on. It looks like it's glowing in the dark or some junk, and you can see a weird pattern like something smudged across the screen.
Is this the type of thing you're talking about? That our devices, when showing black, are actually working to show that black and not just "turning the pixel off" er whatever?

Yes, if I'm understanding you correctly that is what I'm talking about. That glowing, almost grey effect shouldn't need to occur in order to show black. I hope it is something that can be hacked, but I don't know.

I guess this makes me lucky to have 1 pixel stuck on blue. I can easily see the screen turn off in almost any lighting condition.

Couldn't it be that what you're seeing is some kind of residual charge left at power off or some pixels that change states at slightly different rates? I've seen it too and it seems to be a different pattern every time. Also, some of the forums regarding screen burn have talked about samoled break-in so maybe that has an impact as well. Can't factor out power supply leakage either, I guess.

It is true all of those things could be probable, but in order to prove that the pixels aren't turning off you could disable the lock and screen dimming functions with an app and display a black image. Then in low light conditions you could easily see the blacks are actually a very dark shade of grey. If the pixels were turning off the image would over time obtain deeper blacks as the residual charge runs out.
I, and many others, suspect the phones are programmed to not turn off the pixels. Only question is, why? The only thing this type of test wouldn't be able to prove or disprove is power supply leakage.

That sucks to have a stuck pixel! Have you tried having the phone replaced? I don't know for sure but a stuck pixel might fall in the manufacturer defect category, so you might be able to have the phone swapped for free?

Or you can go and download Screen Test and get to the black screen part of the test. It is so hard to notice, but blacks are ever so slightly lighter than if you were to turn the screen off, but it is really hard to catch. Either way, they trump any LCD black levels. They even make my Panny plasma look bad

It's only one and it's on the side, it does work sometimes. I use noled and it seams to come on at the exact same time as the notifications. Cover the proc sensor and it turns off.

Have you tried jscreenfix from the market? It's free and alot of feedback suggests it can work on stuck pixels.

Calm down man, was just a suggestion lol. But that's interesting, considering mine is extremely noticible in darkness even with the brightness turned all the way down. I suppose each phone would behave differently in this respect though.

Well I guess that isn't too bad, hopefully it isn't a sign of things to come. Back when I had my Storm 1, I had a red stuck pixel. It wasn't too bad either until it started spreading a few months later. That's okay though, I was one of the lucky ones who got a Storm 2 as a replacement from Verizon. If you havent, you should definitely try that app mentioned above though.

Red laser bad for our Epic screens?

Since our Epics have Super AMOLED screen being organic in nature I know certian lasers will mess up the screen. The blue one being the worst but what about the red ones like a store's scanner?
Here is a news article about Starbuck's idea of paying coffee with your phone:

No it will not. you'd need like a week of nonstop laser being directed at the screen. Besides, the Sun is far more powerful.

If they are going to have a barcode reader it will most likely be a camera and not a lazer...I dont think lazers can even read off a screen...your screen emits light...you cant pick that up with a red lazer...

Actually, you kinda are being a ****, and saying that you aren't doesn't magically negate that fact. Also, the black on our screens is NOT a complete absence of light - turn your phone off (shut down, not screen lock) in a completely dark room to see just how much light comes from the screen (you can try loading an all-black image file as well). And I don't want to get all physics on you, but the screen would refract the laser, which may or may not cause problems. But any scratch on the screen would interfere, and Starbucks can't predict where or how people will scratch their phones, or what type of screen protector they might use, so that method would be too unreliable to work with the general public

Just for the point of clarity, an AMOLED screen does indeed use NO light to represent black. AMOLED displays do not use a backlight so black is "rendered" by simply not turning on any color for the pixel.

Wow. Way to troll my post. I'm sorry but that was completely unnecessary.
Indeed the glass and scratches can present refraction problems, but that is why it must be done nearly face on, and why barcodes are so tall, because physical scratches on a barcode can have the same consequence of a failure to read.
Also...I never argued it was perfect. In fact, I agree that the glass alone presents an issue in reliability.
But I never mentioned the glass, because that was not the point I was making. If you read my post, and use some basic intuition, you'll see that I was merely pointing out that it is incorrect to think that light emitting from my screen is different than light reflecting off your bar code. He had, in effect, argued the opposite previously.
And you really mistook the voice of my post. My preamble was cautionary because I didn't want to sound like a, well, ****. And my conclusion was simply reaffirming that. If you reread my post with a more hesitant voice you'll understand how I wanted it to sound.
Then again, it's not like we're talking face-to-face. I can't really blame you for misinterpreting like that, because automatically placing an insulting voice in there would be your problem, not mine.

LOL.... Plus one for that joke!

Reading through the posts some interesting points. However, this isn't about scanner NOT being able to read the bar codes on our Epic screens. It's about the possible damage caused by a narrow beam of light enegry for any length of time.
I know regular LCD screens aren't affected by this but AMOLED is sensitive to UV light such as the sun.
Here is something I saw on Wiki:
"UV sensitivity: OLED displays can be damaged by prolonged exposure to UV light. The most pronounced example of this can be seen with a near UV laser (such as a Bluray pointer) and can damage the display almost instantly with more than 20 mW leading to dim or dead spots where the beam is focused. This is usually avoided by installing a UV blocking filter over the panel and this can easily be seen as a clear plastic layer on the glass. Removal of this filter can lead to severe damage and an unusable display after only a few months of room light exposure."
I have to wonder just how strong can the UV fliter on our phones protect the display? So far my normal usage on the phone the display looks fine. Then again I made sure it wasn't left in the sun too long, maybe like a few seconds.

Dont these mobile screens have any threshold temperature values to turn off when reaching such temperatures???

Nothing to do with heat, research amoled displays. The more you use a particular color the less bright over time the color pigment will be. Blue lasts the shortest, then green then red.
On my old galaxy s, the clock made a set of "burnt in" pixels in its place. On an all blue screen, the clock had obvious burn in, green screen less noticeable, red not noticeable. One idea could be to lower the brightness to reduce the effect, but it WILL happen to some degree. For me it isn't noticeable unless I look for it...
The ring you see is actually not "burn in" in the sense of old CRTs or plasma, in fact its the opposite. With burn in, if blue "burns in" you always see blue. Amoled is the OPPOSITE. The reason the ring above appears to be redish-green is because the blue is "depleted" more so than red or green. As I said before the colors deplete at different rates, thus blue will burn out sooner than green, green sooner than red. So for the ring you see above, on a screen meant to be 100% white, your "ring" will be maybe 80% blue, 95% green, 100% red based on how much brightness each sub-pixel has lost.

Thank you for this answer. Now, I understand that the screen is "used" and not burnt.
Always using auto brightness.

I can see a difference in the notification bar area when I put the phone in landscape, eg in the browser.
I've got the phone about 3 months and a half ago.. I've pretty used the phone. Using auto brightness.

I noticed over the last few days some burning in. I went to start a thread to see if anyone else had this and there is a thread also underway in the Q&A section http://forum.xda-developers.com/showthread.php?t=1284984

That means any app that stays open (i.e. Car Home) can damage your screen. I had no idea, thanks. At least Car Home has the screen 90% black...

Thank's for the heads up and I will try not to use blue no more. (I did not think it would make a screen "burn out" so fast.) My 5 year old 32in Lcd hdtv I had dimed out to the point were it started becoming hard to see movies with dark themes. (I now have a 46in LED tv)

yep. I have Samsung Omnia II - first Samsung phone with AMOLED display. And noticed that time that blue pixels wear very fast.
It's pretty similar to plasma displays.

Yeah, a little research on AMOLED screens will reveal their struggles with finding blues that last anywhere near as long as green, much less red. Since it's an organic compound in the end, it's going to have a somewhat limited lifespan. How long it'll really last is going to vary by use, brightness, and luck of the draw.

Awww nuts!
That's a bit off-putting really but I'm glad I found out about the screen issue. I'm having a real to-and-fro battle trying to decide which phone to buy, Sensation or GSII. Each have their pros and cons.

when i had my mobile for like 3 days i was playing fruit ninja at highest brightness and all the slashing on the screen after 3-4 min i had a warning that screen temperature is high and it reduced brightness automatiacally but nothing happened to screen

Thanks for sharing this info, RaPiiDe. And thanks to ompuw22c for explaining this amoled specific issue.
Did anyone managed to get screen replaced, does warranty cover it?

My GS is almost 2 years old, but the screen is perfect. I guess that's because I set the screen the lowest bright unless I use it outside. Even though it's lowest bright, the screen is bright enough to do almost everything. I love superamoled.

A respectable night docking app must do two very important things right:
a) must lower brightness to minimum
b) must move the image left/right/top/bottom by a few pixels every so often , to minimize strain on pixels.

Just so no one gets confused here: "Organic" in OLED does not mean "material came from once-living organism, or is a product of decay". It instead means "made from an organic compound" - where "organic compound" is a material that contains carbon. Another example of an organic compound is diamond. Carbon is basically everywhere

I have terrible usage from PowerAMP in car mode. Just got my USB jig though. Will most likely send it in for replacement.
