reduced power/burn-in theme?

OLED on the S2 is awesome but the because its "+" the blue materials decay almost 5x faster, meaning color balance issues and burn-in. But wut about a pure black theme with yellow instead of white for letters(or just green, but only 1 sub pixel is twice as grainy as 2)and red for dividing lines? May not sound pretty, but I would appreciate it for my galaxy s, and used S2 owners would appreciate it the most by improving the screen longevity on one of the sexiest phones released.

+1 to your request.. I was using a sense 4.0 inspired theme, very bright colors.. The other day I just checked the phone in Test Mode, to my horror the status bar had burnt in.!!
I checked my warranty, had 27 days remaining so got the display unit replaced.. I dont want this one to go bad in 11 months..
Hence, I request too..!!!

Even tho i agree with your request and +1 for it, you should try screen adjuster from the market.
Ofc it doesn't save your screen colours but definately makes it look as it should with the right settings.

Burned in images of stock arangment of apps?

So i just bought a used galaxy nexus and have been using for a little while and i keep noticing that it looks the stock arrangement of apps on the home screen are liked burned into the screen. Like i can see them everywhere i can go and more depending on what color the screen is at. Its not software because i booted into CWM and i could seem them. Is this a defect? Or just the nature of the phone? I have tried to take some pictures but they didn't turn out to great......
Here is a link to the high quality version of the picture https://www.box.com/s/bv84z7gu0dsltgzorevi

Normal good sir.
Pretty much any used Galaxy Nexus will have some burn-in, as the display is AMOLED. Happens with all of our Galaxy Nexuses, I guess we kind of just accept it though. lol
The way the Nav Bar sits, we all will probably have it burned in sooner or later, many already have it...
Just as well, look at a black background with the display on and you'll see blotches on the screen, also normal. There's actually a sticky here about what's normal and what's not.

S3 Screen

I don't know much about differences in screen besides what DPI and resolution is, but yesterday I was looking at some pictures and icons on my S3 and iPod 4gen and I noticed that the iPod screen was much much brighter than the S3. And because of that I was able to distinguish gradients and textures better.
So my question is, is the screen on the S3 dimmer than on purpose or is my screen defective.
-- just in case anyone was wondering I had both devices on full brightness.
--something I noticed was that if I put the iPod at half brightness, then that would be about as bright as my S3 on FULL brightness.

Did you try turning the brightness on your s3 up?
Edit: oops I see that you did. I dunno take it to a store and compare your screen to another s3.

Yes. The screen is dimmer. Samsung cut the maximum display power to 1.3 watts allowing for a longer battery life because of how big the screen is. Also has to do with the candelas per sq inch on a screen.

Ah I see. Is there a way to maybe to make the screen brighter some how by increasing the voltage or something.

You are comparing apples to oranges. The S3 uses samoled+, which presents blacks much deeper and whites so so. This makes for brighter whites and not so deep whites on the crapples devices giving the illusion of brighter screens. Just like comparing a plasma to an LCD. Yes there is an app to make the screen brighter, and you must be rooted. Just install the app and run it, must be clicked once per boot to work as it runs a command in the interactive shell.

Thread cleaned a bit.
Always fond of this saying: "Work the problem, not each other."

Has anybody else used that apk? Does it work? I don't want to mess up my brightness levels using it. I should be able to reboot and go back to normal but still cautious about trying it.

I just installed it and ran it. I granted it permission but I don't see any difference.
Thanks for the info on the screen by the way

You have to have autobrightness disabled and turn the brightness all the way down before running it. I am using it and the results are blinding !

Lol why do you need it brighter? It blinds me on full brightness. I always keep my half way and it's perfect.

I still can't get it to work. I turn off automatic brightness, then lower it all down and run the app, then increase the brightness back up and still the same.

4.2 Daydream and it's effect on battery

Daydream sounds awesome. I have it displaying the clock while it's charging. My questions is, how much drainage is it doing to the battery while the screen is on?
For instance, if i had the screen completely off, I would have reached 100% in 1 hour rather than 1.5 hours since I have day dream working...?
So how much drainage?

For me it charges at the same rate with daydream on(of the wall)

What concerns me more than charging rate is screen degradation, AMOLED screens degrade over time so I wouldn't keep my screen on if I wasn't using it

Exactly, you risk burn in by using this feature too much i think

This might be why Google switched the display type from AMOLED to the LCD in the nexus 4.

I think it was LG's choice and I think LCD is cheaper.

Are any of the daydreams even static? I assumed that the reason the clock bounces around is to avoid things like burn-in.

The standard one is static, some of the third party ones are not. I really wouldn't worry it too much.

Check again, the standard daydream clock is not static, at least the digital one isn't.

i lost my original charger!
Sent from my Galaxy Nexus using Tapatalk 2

it isn't just about burn in... amoled pixels do degrade over time like another user said,and this is a dangerous way to screw up your screen much quicker.
not a good feature to use on our phone imo

It takes a long time for that to happen there are plenty of people still rocking a Galaxy S1 and the screen is fine but I'm not saying there's no one with problems but I doubt it would mess up by using daydream
Sent from my Galaxy Nexus using xda app-developers app

Ya, the digital clock is not static. However, I would worry more about the navigation bar because that thing is gonna stay in landscape mode and I already got a nav bar burn-in in portrait.

depends, is it on overnight? Say you sleep 8 hours that's 8 hours extra the pixels are on per day.
Do the math, it would add up quickly

burn in only occurs when you have an static image in the same place all the time.. daydream move the clock around the screen every few seconds, and with the black background most of the pixels of the screen are off anyway.
so no, there is no danger using daydream.

I'm not talking about burn in....
do you not know about the degradation of amoled pixels over time?
you could end up with dead/stuck pixels a lot earlier than expected.

Best Wallpaper Color for Sunlight

I love wallpapers but I wanna know what the best color to have is if you go outside a lot. I know on AMOLEDs that black saves battery, but with a strong sun you can't see much on a dark wallpaper and turning up the brightness might offset battery gain. Yet white is both very difficult to see in the sun AND takes up more battery. What is the best wallpaper color to have for the sunlight?

i'd like to know. My Droid Ultra red cube wallpaper is getting old.

I don't know? Blue? Lol I think you should experiment with that. There is no definite answer to this question.

I don't claim to know anything, but in my experience I've found white w high brightness is best for sunlight but bad on battery and black at night w low brightness is best overall on battery. Hope it helps some.

Yeah that's what I'm thinking, but black makes it impossible to read in direct sunlight. White is the easiest, but it drains the most battery. That's why there can't be a straight answer (in my opinion).
