Do not be surprised to hear that the Galaxy S9 and Galaxy S9+ are not going to be making an appearance at the upcoming CES 2018 trade show. Fortunately, Samsung is not going to keep you disappointed because these devices are going to be unveiled very shortly after if a new leak is to be believed that is.

Samsung has notably been present at the MWC trade show alongside manufacturers like Sony, LG, and others and according to The Bell, the company is expected to be unveiling its Galaxy S9 and Galaxy S9+ on February 27. Now keep in mind that the CES 2018 trade show is going to start from January, and MWC 2018 will start from the last week of February so there is not a whole lot of differences in between the two trade shows.
