The US unlocked Galaxy S8 and Galaxy S8+ are receiving updates this morning, bringing them up to the July security patch. The builds are listed as G950U1UEU1AQG2 for the S8 and G955U1UEU1AQG2 for the S8+.
In addition to the bump in security patch level, Samsung also details the ability to hide the on-screen navigation bar, as well as changes to the colors available for it. Following the update, the navigation bar will be set to the default color. This is the same change carrier units saw earlier this week.
US unlocked owners, go grab that update.
