Early in 2013, BlackBerry brought out its first devices bearing its revamped OS, BlackBerry 10.
The operating system's flagship, the Z10, marked a departure in design terms — the touchscreen device moved away from the rounded and bubbly feel of the older BlackBerrys in favour of a sharper, sleeker rectangle.
The touch-centric OS brought in new UI concepts, including Hub, Peek and Flow.
The most recently used app is shown to the top left of the screen with up to eight of the most recently run apps alongside.
On the hardware side, the Z10's core specs included a 4.2-inch display with a 1280 x 768 pixel resolution, 1.5GHz dual-core processor, 2GB RAM and 16GB of internal storage, expandable up to 32GB with a microSD card.
