Quite awhile ago we revealed that BlackBerry 10 would offer a light and dark theme. Though, it will only be available with devices that have OLED screens. That’s why the dark theme is missing from the BlackBerry Z10, which uses LCD.

By using a dark theme, your power consumption will be less and you’ll thereby save battery life. The BlackBerry 10 Dev Alpha C has an OLED screen and thus has let us witness a dark theme for BlackBerry 10.

On a BlackBerry 10 device with an OLED screen the dark theme doesn’t look like it can be changed to white. Though, the way OLED fires each pixel to render an image you would likely see unsatisfactory battery life if you could change the theme to white. Nonetheless, gaze your eyes upon the photo above of BBM in a dark theme.

Thanks Taylor!
