Samsung did not immediately respond to a CNET request for comment. However, this matches up with earlier reports that its first 5G phone was expected to land in Korea first and was not expected to be the main Galaxy S10 device. Also, the electronics giant did have a 5G prototype under glass in its booth at CES 2019. 

During CES, the company announced the launch date for its 10th anniversary Galaxy phone so we'll have more answers soon: The event is scheduled for Wednesday, Feb. 20, at 11 a.m. PT at the Bill Graham Civic Auditorium in San Francisco.
