All Samsung has to say officially about the upcoming Galaxy S21 series is "A new Galaxy awaits." It doesn't even mention what model name we're going with this year. Except there's a subtle change between the dates 2020 to 2021 in the teaser video now up on the company's YouTube channel. It also shows the evolution of the Galaxy S series through the years. But Samsung didn't even reveal the date of its next launch. Rumours have been going around that the launch is happening soon (as early as January 14). So, the wait to hear more about this new Galaxy shouldn't be too long.
