Meanwhile, Google has promised to launch its next phone with a brand new chip, and its first Apple Watch competitor, this fall.
Samsung typically announces new earbuds, tablets and smartwatches to compete with Apple's iPad, AirPods and Apple Watch, too.
It also announced the Galaxy Buds 2 headphones and the Galaxy Watch 4.
