You do not need to have a recent Android 9 smartphone to enjoy the monochrome mode. The option is well hidden, but it is there … Let’s see how to activate this mode to save energy and get out of its bubble …
The option of Android 9 to switch its grayscale display in the top scrolling menu is not really new. This option, much more accessible in the latest version of the OS, was already present in the Options for Developers of previous Android opus. Be careful, do not confuse this mode with the mode Dark which allows not to damage too much the eyes if you use your smartphone without external light.
But then, why use this monochrome mode when you have invested in a 6-inch OLED screen? This is both saving battery in case of emergency, but also to make your smartphone a little less attractive. In the office or during a family reunion, you will have less desire to look at your screen: guaranteed effect!
