Samsung Galaxy S6 Edge: How to Enable Grayscale Mode in Android 5.1.1 Lollipop

Grayscale is an accessibility feature in Samsung Galaxy S6 Edge that will let you turn everything on the display to black and white. This feature can be used to provide you an alternative way to save more battery power if you're tight with your battery life issue, help you easily read or see what's on the screen when you're in a darker area or if you have certain vision difficulty, etc. But, you have to remember that this feature effects the screen only. As the example, the result of photos, videos, or screenshots taken when grayscale mode is enabled will be saved in full-color.


How to enable grayscale mode?
As the example, we'll turn on this feature by using two different methods: from the settings menu and from the direct access menu.
