We have a lot of different companies trying to solidify their foundation in the VR industry. From standalone units meant for the PC with products from Oculus and HTC, all the way down to cardboard viewers from some who are just wanting to use the platform for marketing. A lot of these platforms are trying to isolate themselves from the competition in hopes of obtaining more marketshare for themselves, but Google is taking a different approach with Daydream.
Much like how they handled Google Cardboard, Google wants to bring in as many devices to Daydream as possible. Granted, this can be described as their own platform similarly to how Samsung has theirs with the Gear VR, but Google is actively working with other OEMs to add support for Daydream. There are a number of hardware and optimization targets these OEMs have to hit in order for their device to be eligible, but the Daydream View is capable of working with devices from other OEMs whereas the Gear VR is not.
Adoption rate of Daydream’s platform has been much slower than Google Cardboard because of these requirements, but Google expects 11 devices to support it by the end of this year. So far, only a handful of devices on the market have support for Daydream. This includes the Pixel, Pixel XL, Moto Z, Mate 9 Pro, Porsche Design Mate 9, Axon 7, and the Zenfone AR from ASUS, but more are coming. Google has even just announced the Galaxy S8 and S8+ are getting the update right now.
Support for this is being added thanks to a new OTA update so it could take a bit of time before your device receives it. Those who purchased the Galaxy S8 or S8+ from a carrier will need to wait for an approved OTA update before they receive it. Reports from the community say Daydream applications and games will not work in the Gear VR though, so customers will need to purchase a Daydream View in order to enjoy the content.
