I'm sure you all know our Vibrant's SUPERAMOLED uses much less/no power when dysplaying black and a TON of power when having to dysplay white pixels.
You also all know that most websites are white with black text. My idea is to invert this in browsers such as DolphinHD, the default Android Browser, and whatever other browsers there are.
How would it work? Ideally as a browser plug in (DolphinHD already supports addons) that inverts background color on websites if it detects white and inverts text color to white. It would NOT touch any other color nor the images, video, animations on websites. Just the static background would be black if it's white by default and the text would be white.
That way, a lot of power will be conserved, even on full screen brightness.
Since I do not have the time or expertise to do this, I am just offering the idea for a dev to look into if interested.
Good idea but what about black within photos and such? that'd be insane.
Umm...Inverting colors in photos would just ruin the pictures I think.
I was talking about making the addon look for the html/php/etc tags that specify color for the background and text of a page upon load and alter them before passing it to the browser to load.
Just change the white background to black, and white text to black. No need to invert colors.
Some one must be able to do this... come on!
Looking desperately for the same funcionality!
I think that is a great Idea, I was thinking about that. In the app youverison
It's a bible app. They have a low light setting, turns background black and font white.. I was thinking how great that would be for web browsing.. it seems like an impossible task.
Somebody posted a thread about this a while back. I would love to see oit done, easier on the eyes as well as battery. Steel had this option for one version a while back, or it might have been Dolphin, so it can be done. Adilko and most of the Ereaders have this functionality.

I am using Galaxy S I9000 and I would love such an app. One of my favt website popurls.com is one such site, uses black background and blue text. Also Blackle is a website which is Google Search with black background. Gr8 idea. Wish some developers are reading it.
There should b a quick button for inverting the colors. So that it can b turned off when not required.
I got in touch with the DolphinHD team, and feedback looks promising. Probably I will write the add-on myself so stay tuned!
Thread moved to General.
Have you tried using cyanogen's screen rendering app? You can choose to render the screen in different colors my G1 has it. I can render the screen in red. I haven't seen this porter to the vibrant though.

I created a bookmarklet to invert colors for people using the stock browser, and perhaps more... http://forum.xda-developers.com/showthread.php?p=17149892#post17149892

Just wondering if anyone else is seeing this same problem. When on a white screen like a Google search or aldiko, where the text is displayed portrait mode to the left and right of where text is displayed there are like faint bleed lines where the text is displayed. I tried with brightness all the way up and for the most part they go away but around 50% brightness if you look closely I can see it. Do any of you see the same thing. Just wondering if the amoled screens are like that the Samsung behold II is like that. But godly enoguh in landscape I don't see it. Just portrait. Just hoping nothing is wrong with my cool new phone.
Here are 2 pix of what I see
http://tauruspc.net/pix/1.jpg
http://tauruspc.net/pix/2.jpg
And a better one. Just look to the left and right
http://tauruspc.net/pix/3.jpg
I *JUST* answered your question on google support lol
I have the same thing but mine is definatly not that easy to see.
I just checked and i cant see what youre talkin about so i guess my answer is no
Talk about ironic timing. Weird will look then. And the weird thing is on xda page I don't see in Google support I do. LOL.
Also, I am using Dolphin Browser not default so that may be in play I'm not sure, try downloading it and see if you have the same problem maybe.
Yeh I will do that mainly seems with just black on white portrait mode like Google support. Not xda though.
Wonder if it has to do with power consumption. It takes more power to display white pixels. With the black on the same line maybe those lines with text are consuming less power on the line making the rest of the LEDs on that line of the matrix receive more power, making them brighter?
I tried for about 10 minutes to make that as unconfusing as possible lol
Makes sense. Weird only on portrait not landscape. but just spoke with HTC and they say that haven't heard of any problems like that and can send this in get a problems like that and can send this in get a temp one while they fix it and then switch around again
haven't seen much improvement setting manual brightness either.
I get the same thing, I think it is simply a scaling artifact. When you double tap to zoom the lines are no longer visible.
You can see this effect in the boot loader, but only adjacent (the right of) to where there is text at the left. if you look down where there is no text, and just white space, the ghosting lines across the white are not present.
either way, doesn't really bother me, you really have to look for them to see them.
Yeh double checking I see it there too. So yeh just not me then. Probably just amoled tech. the kind of blinky static lines is what bugs me. Don't happen that often and still kind of have to look to see those but since I have been using heavily since I got it about every 4- 5 hours I see where it gets like static lines horizontally about one pixel think blinky faintly in random spots all over the screen but kindof like static or noise from chip shielding or bad power frequency.
Hey! Can someone with a note set a pre black background a the lock screen background and report whether it looks normal? Someone had reported a problem with the gallery background with a black image, but I couldn't find a mention of lock screen there. Just google image search "black" and download and set it as lock screen. Seems to be giving me pinkish hues... same image works fine as a desktop background...

Most lockscreen wallpapers look horrible on my Note, not sure if my 240dpi is causing this. I use another lockscreen app set to transparent, so I don't care.
The Note's screen is 24 bit, so a picture with 16 or 8 bit depth might not be rendered properly.
Best to find a 24 bit image to test, try Google search.

Same here.
Good to know that I'm not alone. Every other background seems fine. Same thing happens with the gallery background when the only image in the folder is a pitch black one, right?

Well all those images render fine in other applications on the phone so its the lockscreen wallpaper 'setter' wich messes it up I think.
Ya, I'm pretty sure too that that is the case...
I have a black lockscreen and it looks great.
I have noticed that when I have 'screen filter' app running, it dims the foreground but causes the background to do the 'grey' thing.
I have most of the auto display stuff turned off (auto brightness, auto adjust screen power)

That guy mentions that his blacks aren't completely black. Our problem here is that setting a completely black image as the lockscreen leads to a messed pattern with greyish/pinkish stripes...
edit ; same thing occurs on mine. I even created two black background non compressed, 24 bit, one even with 285 dpi.. both show the wierd little gray stripes on lock screen. only notice it in very dim light by the way and even then if i look very close.
this is what i use. both screens look black as night.

Use the darker red "sun" wallpaper gallery image - awesome on mine!
I have the same problem...
Has anyone tried restoring?
I set a black image and got the very dark grey bars others have described. However, I reset it to the original wallpaper and noticed that the white-ish parts of my background has bars as well! Just not as noticeable, and its only on the lock screen.
This is my background picture by the way:
http://interfacelift.com/wallpaper/details/2754/yellow_autumn.html
There seems to be some kind of gradient over the image on the lock screen - I'm just using the default for now, but if you set the default as your normal background as well as lock background, there's quite a difference. Could it be this gradient which is causing the issue with pure black backgrounds?
I'm using widget locker and here is my lockscreen with the homescreen wall paper which uses solid black background color
I am having the same issue. I just noticed it yesterday. I really thought it had something to do with the phone going below the minimum brightness it was designed for, but if you look at the notification bar it's still a clean black.
My guess is the phone is compressing the lockscreen wallpaper to save memory.

Can people try WL (If you've purchased it) and see if it does the job?
hi all, looking for a rom for my N7 that can change the display to only display red for when i use sky safari on it while out stargazing. (red helps protect night vision) on my nexus one with CM7 it has render effects settings screen where you can change the color of the whole os to basic colors etc. any roms out for the N7 that can do this globally as well? and before you say it yes sky safari has this feature inside, problem is unlock screen does not as well as say accidentally hitting home etc. one bright flash of white light and you loose dark adaptation for 5-10 even 20 min so its kind of important and most people go the easy simple route of putting red cellophane on their screens, but if i can get around that and i know its possible to i would like to.

google skymap has a night view mode built in.

apparently sky safari has a night view mode built in also, look for it in the settings.

yeah sky safari has it, and it also has a setting to keep the device from sleeping because the problem is the lock screen and any other screen you might accidentally pull up will not be a dim red light and will instantly damage night vision if pulled up. anyways i rooted my N7 and took at look at a few roms and so far have not found one with this feature. looks like it was put into CM7 for the potential power savings due to the screen on the nexus one as well as many other phones being AMOLED. on tablets with LCD's theres no savings to be had so nobody's implemented it into a JB rom so far.
Tasker might do what you need. You make a profile to do things like dim screen brightness, change wallpapers, dim/kill LED notifications, etc. Set it to trigger when you open your Skymap app & your light sensor senses that it is dark (I don't know what that setting looks like).
This app has astronomers moder for the red tint.

I'm one of those lucky people who gets chronic migraines. The primary trigger for me is bright light... especially looking at bright, white screens with black text. Consequently, I've spent quite a bit of time trying to invert screen color... which is fine unless you are looking at pictures or video.
I know that I can change my Note 4 settings to invert the colors, but that simply isn't practical. I've been able to get some of the modifications I need by swapping out applications. For instance, I use Chomp SMS and have found a great plug-in for firefox that inverts the color without inverting the images. I've also been able to make some system mods through Xposed using Wanam's module. But these are only bandaids. I'm really looking for something that will work system-wide, for light text and dark background.
My phone is a Sprint Galaxy Note 4 running Lollipop 5.1.1. Does anyone have any suggestions? Would upgrading to Marshmallow help? Or how about changing out the ROM?
If nothing that would work systemwide, does anyone have a suggestion for an email app that will invert the text color? The stock Samsung email app is really tough for me.
Any help will be much appreciated.

My notification panel turns black on its own. Then it stays black for some time and then return to its original white color. Although it is not much of a concern to me, but i would like to know whether this is normal, and what causes the color of the notification panel to change?
Yup .. Noticed that too. My notification panel turns dark when I put dark wallpaper, and when I change to light wallpaper, itu turns white .

Thanks for the reply. I tried it and it is as you said. Never thought of that. I mostly use dark wallpaper so never noticed that. Now i wonder whether this happens with other phones or it is just limited to this phone. Overall, i think it is a great feature.

Material dark theme cannot be implemented system-wide without root changes / third party app. This is default optimization by Google for Android (not their best work for sure), will probably be corrected in Pie.
