About Galactic Night [root, Samsung]
NOTICE: Galactic Night has been discontinued, though you are free to keep on using if it works. If you have Android 4.4 or newer, try our Color Changer Free app instead.
Galactic Night is an experimental nightmode app for rooted Samsung Galaxy S2, S3 and Note 1 phones (don't bother trying on other devices) that lets you set various color modes on your phone for use in the dark, to save batteries, for astronomy, ebook reading in the dark (and during the day) and for other purposes. Currently supported special modes on many devices include: red, green, blue, no-blue, sepia, black and white, reverse and outdoor. E.g., in red mode, everything is rendered in shades of red. In reverse, all colors are reversed, which is nice for web browsing at night. In sepia, white is replaced with sepia.
Monochromatic color modes like red and especially green (because our eyes are very sensitive to green light, you can use lower intensities with green than with red or blue and still preserve visibility) can save batteries by using only one color of AMOLED subpixel. Moreover, except on some devices (e.g., the American version of the S3), these modes are designed to preserve maximum device usability: they don't just drop the other components of the colors, but use the overall luminosity of the pixel to set the red or green intensity, which means that even in red and green mode, blue things can still be used.
Because Galactic Night uses your Galaxy phone's mDNIe system, it should not significantly impact graphics speed.
WARNING: THIS IS EXPERIMENTAL SOFTWARE REQUIRING A ROOTED DEVICE. USE IS AT YOUR OWN RISK. In particular, there is a danger that that using modes like red, green, blue and no-blue regularly and for too long, especially at too high intensity, will result in burn-in on the AMOLED display, resulting in a color tint.
The black and white and mono sepia modes are useful for reading ebooks even in daytime with ebook reader apps (like the last version of the Kindle ebook that I tested) that incorrectly use subpixel rendering which results in colored fringes around letters in some orientation. The black and white and mono sepia modes fix this.
Unfortunately, the hardware on the US (or at least Sprint US) versions of the Note and S3 uses a different display controller from the international versions, and this display controller does not work for the black and white or mono sepia modes. I've also have not been able to get this working on 4.3 on the US Sprint S3.

A friend told me of this app while ago. I don't really hardly ever use but I find it is a really nice root app. If for anything I'd use for outdoor control for seeing screen easier but usually I see my screen just fine. Galaxy note 2

I found that black and white is best, and then I'll invert the colors when I have more white than black on screen (while reading text, you can have white letters on a black background). If you have an AMOLED screen and a compatible device, you can certainly save some battery here. Also, a very simple interface and strait to the point.

Thank you, Developer! I get that you have other priorities, and that this is a free app. I just wanted to report that it's working great on my rooted AT&T Samsung Galaxy Note II (SGH-I317), running stock 4.4.2. Nice job, and again, 5 *' s. Thank you!

Perfect replacement app for devices without Ultra Power Saving Mode. If I enable the build-in power saving mode in my Galaxy S3 + this Galactic Night app in Black & White, my phone can stand for days without charging!

Just want to thank you from the core of heart for this awesome app. Works perfectly fine on my Note 2. I was really searching for this and came to know about from an Android forum. The Black & White mode is great. Keep up the good work :)

Worked great on stock Sprint Note 2 and CM11. Just installed a stock based 4.4.2 ROM and no longer works. I know it's experimental though so that's the chance I take.
