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.

注意：银河之夜已经停产了，虽然你可以自由地继续使用，如果它的工作原理。如果你有安卓4.4或更高版本，我们尝试换色的免费应用程序来代替。

银河之夜是植根三星Galaxy S2，S3实验夜间模式的应用程序和注意1手机（不要打扰试图在其他设备上），可以​​让你在手机上，在黑暗中设置各种颜色模式的使用，节省电池，天文学，电子书阅读在黑暗中（白天）和用于其他目的。在许多设备上目前支持的特殊模式包括：红，绿，蓝，没有蓝色，棕褐色，黑白，反转和户外。例如，在红色的模式，一切都呈现在不同深浅的红色。相反，所有的颜色被颠倒，这是很好的进行网页浏览在夜间进行。在深褐色，白色被替换褐色。

单色模式，如红色和绿色尤其是（因为我们的眼睛是绿色的光非常敏感，可以使用强度较低的绿色比红色或蓝色，仍然保持可见性）可以只用一种颜色的子像素的AMOLED的节省电池。此外，除了在某些设备（例如，美国版本的S3的），这些模式被设计成保持最大设备可用性：他们不只是下降的颜色的其它组分，但使用的像素的总亮度设定红色或绿色的强度，这意味着，即使在红色和绿色的模式，蓝色的东西仍然可以使用。

由于银河之夜使用您的手机银河公司的mDNIe系统，它不应该影响显著显卡的速度。

警告：THIS IS实验软件需要root权限的设备。用的是AT您自行承担。特别是，有一种危险，即，使用模式，如定期的时间过长的红，绿，蓝和无蓝色，尤其是在过高的强度，会导致老化中的AMOLED显示器上，从而产生一个色调。

黑色和白色和深褐色单声道模式是阅读电子书，即使在白天与电子书阅读器的应用程序（如Kindle的电子书，我测试的最后一个版本），其错误地使用像素渲染导致各地在某些方向的字母彩色条纹非常有用。黑色和白色和棕褐色单声道模式解决这个问题。

不幸的是，在美国（或者至少短跑美国）的注版本和S3中的硬件使用来自国际版本中的一个不同的显示控制器，并且该显示控制器不为黑白或单棕褐模式下工作。我也一直没能得到这个工作在4.3对美国的Sprint S3。
