The Galaxy Z Fold6 has two displays: a 6.3″ Cover-Display (classic glass, classic 9H tempered glass possible) and a 7.6″ Innen-Display (faltbar). Important — inner display: the foldable inner display cannot be protected with classic tempered glass — the glass layer would crack on folding. The factory ships a UTG (Ultra Thin Glass) layer plus polymer film that you should not remove yourself. For additional protection only soft, flexible hydrogel films from third parties qualify (self-healing for micro scratches, fold-compatible). For the cover display we carry 9H tempered glass models (full glue, clear, oleophobic coating) — especially relevant on the Z Fold since the cover display handles all calls, quick notes and camera viewfinder, and on the Z Flip (the FlexWindow on Flip 5+ is effectively the primary screen for notifications and quick replies).
S Pen Fold Edition: the Galaxy Z Fold6 supports the dedicated S Pen Fold Edition with a softer tip, certified specifically for the foldable inner display. Important: a regular S Pen (e.g. from Galaxy Note or Tab) must not be used on the inner display — the harder tip can damage the polymer layer.
