It is aimed at military use.

Samsung has released the Galaxy S20 Tactical Edition phone. This device is ultra-rugged and tough and the idea is that it will be used by armed military forces in the field. It uses an Android operating system and can integrate with radios, drone feeds, and GPS. Samsung’s goal is to ensure that this new, tough phone should be a cornerstone of any form of mission planning.  The Galaxy S20 is not available for general sale; it can only be purchased through specific channels for the Department of Defense and federal government in the USA.
