Samsung Galaxy Z TriFold: A 10‑inch Foldable Phone

• Key Takeaways:
• Samsung’s Galaxy Z TriFold adds a third display panel to deliver a 10-inch screen, positioning it between phone and pocketable tablet.
• The TriFold is exceptionally thin when open (3.9mm) but thicker folded (12.9mm); it’s roughly 50% more substantial than the Z Fold 7 when closed.
• Two visible creases, fixed-angle folding (0° or 180°), and limited tent-mode usability change certain Z Fold use cases like propping for selfies.
• Software features include DeX, One UI, Galaxy AI, and Google Gemini; the phone carries an IP48 rating and likely a premium price above $2,000.

What the Galaxy Z TriFold is

Samsung’s TriFold takes the Z Fold 7 concept and stretches it into a three-panel device that unfolds into a roughly 10-inch display. Shown at CES 2026, the handset is designed for users who want a true tablet experience that still fits in a jacket pocket.

Design and dimensions

The TriFold measures a razor-thin 3.9mm when fully open and 12.9mm when closed. For comparison, the Z Fold 7 is 4.2mm open and 8.9mm closed, making the TriFold about 50% thicker in its folded state.

Build quality and materials feel premium, and Samsung’s refined hinge engineering delivers smooth, reliable motion. The folding sequence is precise: you pull back the rear panel first, then the inner panel; sensors will warn you if you try to close panels in the wrong order.

Display, creases and usability

The 10-inch interior is bright, colorful, and sharp, but it shows two visible creases—more noticeable than the Z Fold 7’s near-flat inner screen. Those creases are apparent from most viewing angles except straight on.

Unlike the Z Fold 7, the TriFold won’t hold intermediate angles; it only stays fully open or fully closed. That removes tent-mode and laptop-like half-open positions that some users rely on for propped selfies or staged video shots.

Software and performance

Samsung ships the TriFold with One UI plus DeX, which adapts the large display into a Chromebook-like workspace useful for emails, presentations, and multitasking. Galaxy AI features and Google’s Gemini are included, and core hardware—processor, cameras, memory, and storage—mirrors Samsung’s flagship foldable specs.

Who should consider it—and price

Samsung reps say the TriFold targets a different customer than the Z Fold 7: people who prioritize a tablet-grade screen in a pocketable device. Expect a premium asking price—likely north of the Z Fold 7’s ~$2,000—making this a niche purchase for those who want a pocket tablet and don’t need mid-fold flexibility.
