SEOUL (Reuters) - Tech giant Samsung Electronics Co Ltd said on Friday it will hold a press conference on Jan. 23 on the Galaxy Note 7 with the head of its mobile business Koh Dong-jin in attendance.

Samsung did not elaborate on what will be discussed at the briefing, but said earlier this month it will soon announce the results of its investigation into what caused some of the Note 7 smartphones to self-combust. On Monday, a person familiar with the matter told Reuters the probe found the phone's battery to be the main cause.
