The RoadtoVR website has recently found something interesting in the latest Compatability Definition Document for Android, which describes what’s exactly required from a Daydream-ready phone.
The hardware requirements don’t seem to be high – Regarding the display specifications, Daydream View requires at least a 1080P resolution and strongly recommend to be 1400p or higher, measuring between 4.7″ and 6″. Google has also claimed that the device should maintain 60Hz in VR mode, and no more than 3ms in switching time.
Daydream View requires the phone to pack at least two physical cores, with an exclusive core assigned to the VR app, on which no other processes should run. In terms of rendering, device implementations must support OpenGL ES 3.2 and Vulkan Hardware Level 0. Actually, Vulkan Hardware Level 1 is preferred.
For the time being, Motorola’s Moto Z and Moto Z Force have realized support for Daydream View besides Google’s own Pixel and Pixel XL. Regarding the hardware requirements, there’re lots of 4-core 2K smartphone available on the market, but the heat or battery life could be a problem.
