Samsung and Oculus VR are developing a virtual reality device in close cooperation. Samsung gets access to the software - John Carmack developed for Samsung special tool that allows you to use the smart phones of this brand to work with the technology of virtual reality. Existing prototype uses Galaxy S4, and as standard can be seen Galaxy S5 or even more modern smartphone - presumably with OLED-display.
By the way, access to advanced OLED-displays pushes Oculus VR to cooperate with Samsung. It is assumed that this Korean manufacturer will supply Oculus VR type OLED displays for their own virtual reality device, which will be released under the wing Facebook. Perhaps the resolution of these displays will exceed 1080p.
