The Galaxy Note 8, Samsung's yet-to-be-released smartphone, has another spec to its name: its the fourth smartphone to support HDR video from streaming giant Netflix, according to Netflix’s support page (opens in new tab) (spotted by SamMobile). The others in that range are the LG V30, and Sony’s Xperia XZ1 and XZ Premium phones.
HDR, or 'high dynamic range', aims to heighten the contrast between the brightest whites and the darkest blacks, and as such deliver a more realistic picture.
The Galaxy Note 7 was the first Samsung smartphone to support HDR (yes, the one that exploded - but there is a new one), with the Galaxy S8 and the Galaxy S8+ following suit. However Netflix, one of the primary providers of most people's HDR content, didn't allow support for high dynamic range on those mobiles. As such, it's possible that older Samsung devices will receive an update when the Note 8 is released on 15th September.
However, HDR does have some competition: rivalling firmware comes from Dolby Vision, which adjusts the picture frame-by-frame to theoretically give greater accuracy (although we've found that this could vary, depending on how well it is implimented by the disc).
