A setting to turn dark theme was discovered a year ago, in a preliminary version of Android 6.0.
The function expansion never reached crisp version of Marshmallow and now it seems that not even the Android N will get it.
New night mode, which filters out blue light and makes the screen more gentle on the eyes, also looks to be disappearing.
According to Google developer Dan Sandler, it is the very unlikely to night mode and dark theme will be in the final version of the Android N, although it is not entirely out of the question.
According to Google keeps subtleties simply do not measure up.
Although we probably will not get any night mode in Android N is of course possible that Google will succeed with the implementation later.
