They were unveiled during Mobile World Congress in February 2016, and are a successor to the Alcatel OneTouch Idol 3. The Idol 4 and 4S are positioned as mid-range devices, with the 4S serving as a higher-end model with a faster processor, a larger 1440p display, and a bundled virtual reality headset which serves as the device's packaging. The Idol 4 was re-branded by BlackBerry Limited as the BlackBerry DTEK50, as unveiled in July 2016.
