Sources say Samsung may unveil its Galaxy Watch4 smartwatch at Mobile World Congress 2021 on June 28th. Earlier it was reported that the announcement will take place only on August 3.
Samsung has announced a virtual press conference called Galaxy Ecosystem / New Watch Experience / Mobile Security. While it’s worth adding that Samsung can only provide details of the new smartwatch operating system at this event, the source thinks otherwise.

It is expected that the new smart watch company Galaxy Watch4 will receive a 5-nanometer single-chip system, a narrow bezel display, durable protective glass, and a case that will be made of titanium alloy (in the older version). The watch will be running WearOS operating system.
The Galaxy Watch4 is rumored to be available in 42mm and 46mm sizes, while the Watch Active4 will be available in 40mm and 42mm cases.
