🚀 Samsung Galaxy S21 – The Compact Flagship That Changed the Game
When Samsung launched the Galaxy S21 in January 2021, it redefined “flagship” by offering top-tier performance, pro-grade cameras, and 5G connectivity in a sleek, relatively compact form factor—at a lower price than its predecessors.
