Samsung (005930) has released a new teaser video for its upcoming Galaxy S IV smartphone, which is set to debut at a press conference this Thursday. The company issued its first teaser for the new flagship phone last week, launching a narrative that will likely culminate during its press conference. The second installment has now been posted to YouTube and it carries forward the same storyline featuring a young child tasked with being Samsung’s “secret messenger.” The Galaxy S IV is expected to include a 5-inch Super AMOLED display with HD resolution, an eight-core processor, a 13-megapixel camera and Android 4.2 Jelly Bean. Samsung’s second teaser video follows below, and the first can be viewed here.
