I have a Samsung Galaxy S5 and I've upgraded to Android Lollipop version 5.0. I'm wondering why the newer version of Android has forced the white background of the menu/settings onto AMOLED screens? Because you can edit this option in KitKat (version 4.4).... and in Marshmellow 6.0....

This is annoying, now the default color is detrimental to power consumption.
Has anyone found an app for that (not the launcher app, an app for all the menu themes)?
