Curvy sides, flat edges: The Galaxy S25 and the arbitrary shape of smartphones
Samsung's Galaxy S25 has flat sides, resembling older models, sparking discussion on smartphone design evolution.

Samsung's Galaxy S25 series, which includes the S25, S25+, and S25 Ultra, introduces a unified design with flat sides across all models. This design choice marks a departure from the curved sides seen in previous models, resembling both older Galaxy and iPhone designs. Mat Smith explores how smartphone design has oscillated between flat and curved through history, referencing various models like the Galaxy S6 and S8, and the iPhone 6, to highlight the changing preferences in design.
The discussion raises the question of whether these flat sides are easier to hold, with Smith admitting his personal inconsistency in preferences. He acknowledges past praise for both flat and curved designs in his reviews, suggesting some users form attachments based on what they are accustomed to. Despite the ongoing debate, Smith proposes that familiarity with recent devices likely influences user comfort more than specific design choices.
Smith also references an interview with Jony Ive about the iPhone 6's rounded edges, illustrating that design decisions often reflect ergonomic intentions. He posits that the shifts in design by major manufacturers like Apple and Samsung signal broader industry trends, with the return to flat sides potentially driven by both practical and aesthetic rationales. Until an innovative design concept emerges, it seems flat sides are the current industry preference.
