brightness-sliderA Reddit user has posted screenshots from his Lumia 630 and it reveals one useful new feature coming with Lumia Cyan, the upcoming Lumia Firmware along with Windows Phone 8.1.

As the screenshot reveals one can now use a slider to adjust brightness on Lumia devices running Lumia Cyan. Seems for all brightness levels there will be separate brightness sliders and this will enable much better control over display brightness.
