Google released their most recent Compatibility Definition Document for Android that includes a new section specifying whats required from a Daydream-ready phone.

The paragraphs below are from from the following article:

In the most recent CDD, a new entry in the Hardware Compatibility section adds many requirements for Daydream VR. This includes key display specifications, such as requiring at least 1080p resolution and strongly recommend to be 1440p or higher, measuring between 4.7″ and 6″ diagonal. The device must maintain 60Hz in VR mode, and regarding pixel switching, Gray-to-Gray, White-to-Black, and Black-to-White switching time must be ≤ 3 ms, supporting a low-persistence modewhich reduces image blur in VRwith ≤5 ms persistence.

In terms of processing, device implementations must have at least two physical cores, assigning an exclusive core to the VR app, not allowing any other processes to run on it (except device drivers used by the application), but the document stops short of defining minimum clock speed or floating point performance. In terms of rendering, device implementations must support OpenGL ES 3.2 and Vulkan Hardware Level 0 and should support Vulkan Hardware Level 1.

Video decoding is also particularly important for mobile VR, and Daydream-ready devices are expected to support H.264 decoding at least 38402160@30fps-40Mbps (equivalent to 4 instances of 19201080@30fps-10Mbps or 2 instances of 19201080@60fps-20Mbps), as well as HEVC and VP9, decoding at least 19201080@30fps-10Mbps and should be capable of decoding 38402160@30fps-20Mbps (equivalent to 4 instances of 19201080@30fps-5Mbps).

Phew...that's a lots of technical specs for a phone to be "Daydream-ready"! You think your phone might make the cut?

Part of me wishes I would have waited for the XL! BUT the Pixel fits in perfectly. I am getting some pixelation (is that what you call it?)

I think it's better that way, I mean, not giving specific CPU/GPU/RAM but power, so maybe those cheap phones from unknown brands will be able if they meet the minimun of that even not using the recommended CPU brand and model.
