Super slow motion recording is one of the smartphone cameras features nobody needs, but is nice to have regardless. We saw it make its debut with the Sony Xperia XZ2 and other manufacturers followed suit shortly after. The Samsung Galaxy S9 was the first Samsung flagship to ship with 960fps video recording capabilities. However, you can record only about 0.2 seconds worth of footage in 960fps. Today, Samsung posted a Tweet stating that the Galaxy Note 9 can record in 960fps for 0.4 seconds.
