The update is an incremental build from Samsung’s beta program for the Galaxy S8, Galaxy S8+, and Galaxy Note 8, so that’s a great sign for it turning into something official. The small update is only live on the Snapdragon Galaxy S8, but it’ll likely bleed into the other models, too.
Dolby Atmos is an audio technology for media that allows a movie to locate sounds as objects instead of channels. That might sound a little complicated, but it basically allows for a more accurate approach to movie sounds and allows for height sounds in addition to surround sound. Tons of laptops have started including Atmos certification, so it was only a matter of time before it crept into smartphones, too.
Either way, Android Oreo 8.0 is expected to officially roll out to Samsung’s crop of flagship devices within the next few months, so if you’re using a Galaxy S8 or Note 8, keep your ears out.
