Cellular connectivity gets a meaningful boost from 5G support, with reviewers describing it as useful for leaving the phone behind and handling calls, messages, or downloads on the move.
Materials feel premium, with sapphire protection and rugged hardware choices reinforcing the flagship positioning.
Materials are good for the price, centering on aluminum and improved Ion-X glass rather than the more premium finishes found higher in the lineup.
Menus are usable once learned, but the navigation flow still takes some getting used to.

Design is the main visual compromise: some reviewers still like the look, but many describe it as dated because of the thicker bezels and older chassis.
Third-party support is mixed: routing and exports to services like Strava and Komoot are helpful, but missing TrainingPeaks workout support remains a notable gap.
