BlackBerry will be introducing the first-ever dark theme for a BlackBerry 10 device. The BlackBerry Q10 will be the first official BB10 device to offer a dark theme.
The reason behind this is due to the Q10, and future BlackBerry 10 devices, use OLED screen. Whereas, the BlackBerry Z10 uses an LCD screen.
The idea behind a dark theme is for lowering power consumption. Thus, resulting in better battery life. OLED works much differently than LCD. You can see more about the difference here.
Check out the video below and let us know which theme you prefer. If you’re a fan of the light theme, you’ll unfortunately not be too happy to know the Z10 may be the only one to utilize it.
