Samsung is throwing a press event on May 28 in San Francisco to talk about health, but it won't be launching any new products there. Speaking to Re/code, Samsung's Stefan Heuser, confirmed that this is indeed the case. Heuser didn't give any clues as to what will actually be discussed in San Francisco.
So, that puts an end to that speculation, at least for now. The plot thickens to exactly what will be happening on May 28.
