The new Galaxy A8 (2018) and Galaxy A8+ (2018) are the first of the A-series to support Gear VR headsets. This means you no longer have to pay Samsung flagship money to use its VR ecosystem (from videos to games).
These two will become available in early January 2018. Both feature 1080p+ screens – Super AMOLED, of course. The A8 screen measures 5.6” in diagonal, the A8+ is 6” (and they have S8’s 18.5:9 aspect ratio).
You can probably look forward to some Gear VR bundles, the headset and controller currently cost under $100.
