Rumors that iPhone 18 and Galaxy S27 could reshape (or reduce) “base flagship phones” are a dealer signal: the lineup may push customers toward higher tiers, bigger screens, or different feature splits. Dealers can win by controlling the conversation with a 3-tier match (Good/Better/Best), a Storage + Battery Reality Check, and trade-in math that makes the “right model” feel affordable. The goal is fewer returns and higher attach.
