1. From Prototype to Product: A Timeline
| Year | Milestone | Source |
|---|---|---|
| 2021 | First public “Flex G” concept shown (inward‑inward fold) | PhoneArena |
| Jan 2024 – CES | Samsung Display demos updated tri‑fold panels behind closed doors | Tom’s Guide |
| Jan 2025 – Galaxy Unpacked | Brief image of a dual‑hinge phone appears during closing reel, confirming in‑house development | ZDNet Korea |
| Jun 2025 – One UI 8 beta | Hidden animation files (“Multifold 7”) leak, giving the first software‑level look | Android Authority |

2. Design Language: Why “G Fold” and Not “S Fold”
“Both hinges fold inward—what engineers call a G‑shaped fold—unlike Huawei’s S‑style. It protects the screen like a clamshell sandwich.” —Android Authority teardown Android Authority
Samsung’s Flex G layout folds the two outer panels toward each other. Benefits:
- Screen protection with no exposed flexible layer.
- Uniform thickness when shut, easing case design.
- Simpler water‑sealing than mixed in‑/out‑fold (Huawei Mate XT).
Ross Young of DSCC adds:
“A tri‑fold handset using Samsung’s second ‘Flex G’ form factor is penciled in for next year.” PhoneArena

| OS | One UI 8 on Android 16 | Tom’s Guide |
“The titanium‑reinforced skeleton offsets hinge stress without adding bulk.” —PandaFlashPro leak (Chinese) Sina Finance
4. Launch Strategy & Pricing
- Limited pilot rollout: Korea and China first, Q4 2025, to gauge demand. LOS40 PhoneArena
- Mass‑production window: Panels ship in September; assembly ramps October. PhoneArena
- Projected MSRP: ₩4 million ≈ US $2,900‑3,200—about 1.5× a Z Fold 7 Ultra. LOS40 PhoneArena
- Risk factor: Samsung execs openly question “whether consumers are clearly asking for this form factor.” PhoneArena
5. Competitive Landscape
| Brand | Device | Fold Style | Market Date | Notes |
|---|---|---|---|---|
| Huawei | Mate XT | S‑fold (in+out) | 2024 | First tri‑fold in mass market |
| Xiaomi | Concept tri‑fold | TBD | 2025 (rumored) | German press confirms R&D stage Chip |
| Samsung | Galaxy G Fold | G‑fold (in+in) | End‑2025 | Largest panel; highest price |
Samsung’s main moat is its integrated Samsung Display supply chain, allowing custom hinges and UTG/UTG+ glass iterations ahead of rivals. Notebookcheck
6. Expert Voices
- TM Roh, Samsung Mobile President “We are working hard on a tri‑fold smartphone with the goal of launching it at the end of this year… the name has not been decided.” PhoneArena
- Ross Young, DSCC CEO “Flex G panels will ship in Q4, setting up a 2026 consumer rollout—unless Samsung fast‑tracks a pilot.” PhoneArena
- Aamir Siddiqui, Android Authority “The One UI animation leaves little doubt: Samsung’s engineers are implementing a dual‑inward‑hinge solution—this is not a mere patent sketch anymore.” Android Authority
- Luis J. Merino, Los40 Tech “At roughly €2,800, the G Fold could be twice the price of a Z Fold 7—proof that bleeding‑edge form factors still carry bleeding‑edge bills.” LOS40
7. Key Questions Still Unanswered
- Durability: UTG+ glass must survive >300,000 folds across two hinges. Will Samsung certify IPX8 waterproofing?
- App continuity: Can Android app developers optimise for three aspect ratios on the fly? Google’s “Large Screen Library” only targets dual‑screen today.
- S Pen support: Early prototypes omitted digitizer layers to keep thickness down. No credible leak has reversed that yet.
- Weight & battery: Will a 10‑inch screen push the device past 350 g, making one‑handed phone use untenable?
Samsung typically publishes final specs days before pre‑orders; expect answers at its next Galaxy Experience pop‑up (Paris, London, NYC) post‑Unpacked. Tom’s Guide
8. What to Watch Next
- July 9, 2025 – Unpacked: Even if the G Fold skips a full unveiling, Samsung may run another “peek” segment, mirroring January’s teaser.
- September 2025 – Display Week Asia: Panel suppliers lock final yields; a public showing here would signal green‑lit mass production.
- Holiday 2025: Limited retail launch in Seoul and Shanghai flagship stores, with online lotteries for global enthusiasts—Samsung used a similar playbook for the first Z Fold in 2019.
Bottom Line
After years of prototypes and patent filings, Samsung’s triple‑fold dream is poised to leap from R&D lab to the real world. The Galaxy G Fold promises a 10‑inch OLED canvas in your pocket, but also challenges of price, weight and app optimisation. Whether it becomes the next must‑have gadget—or an ultra‑niche tech demo—depends on Samsung’s final execution and, crucially, on whether mainstream users see value in adding a second hinge to an already premium foldable.
