Netflix recently added the Samsung Galaxy Note8, Sony Xperia XZ1, and the LG V30 to the short list of those able to play back high-definition video in HDR. High-dynamic range content offers better contrast than standard content.
The only other handsets capable of supporting Netflix HDR are the LG G6 and Xperia XZ Premium, which have the needed HDR displays.
In order to view HDR content on these handsets, owners have to subscribe to the $12 premium Netflix plan (streaming on four screens and ultra HD resolution).
They’ll also have to ensure the latest version of the app is installed on their phone, and select “high definition” for video playback quality.
