The phone panel measures 388.2 PPI from its1,080 × 2,400 resolution across a 6.78″ diagonal.At a typical phone viewing distance of 10–14 inches (25–35 cm), individual pixels become indistinguishable beyond roughly 8.9″ / 22.5 cm — the 20/20 visual-acuity limit for this density. At 388.2 PPI, the panel is comfortably in Retina-class territory for its use case.

At 388 PPI, this exceeds the ~300 PPI threshold where individual pixels become imperceptible at hand-held distance. This is Retina-class density — sharp enough that increasing PPI further yields diminishing visible returns.
