The Samsung Galaxy Z TriFold is an Android-based tri-folding smartphone manufactured, developed, and marketed by Samsung Electronics, as part of its Galaxy Z series. It was previewed by the S Flex and G Flex folding concept phones from 2022.[3][4] The phone was announced on December 1, 2025 in the form of a press release,[5] and was released in select countries on varying dates: first on December 12, 2025 in South Korea,[6] on December 19, 2025 in Singapore and the U.A.E,[7][8] on December 22, 2025 in Taiwan,[9][10] and on January 30, 2026 in the United States.[11] It primarily competes with Huawei Mate XT/XTs Ultimate Design.

History

Prototype preview

In January 2022 at the 2022 CES event, Samsung displayed 2 tri folding concept phones, the Samsung Flex S, and Flex G as both S shape and G Shape style foldables as a preview of a possible tri folding phone.[12] They made their appearances in CES (2023, 2024, and 2025)[13] and MWC (2023, 2024,[14] and 2025[13]).

In the January 2025 Galaxy Unpacked event, Samsung teased a tri-folding phone during their product roadmap presentation,[15] confirming the development and release date planned for the year.[16][17]

In July 2025, Samsung leaked the Z TriFold's animation files in One UI 8 ahead of its unveiling.[18][19][20] In October 2025, Samsung fully unveiled the Z TriFold's design at the 2025 Asia-Pacific Economic Cooperation (APEC) summit without the name being used.[21][22]

Release

In December 2025, after months of rumors and speculation, Samsung officially announced the Galaxy Z TriFold in a press release.[5][23] Sales began in South Korea on December 12,[6] in Singapore on December 19,[7] and in the U.A.E. on December 20,[8] with a U.S. release on January 30, 2026.[11]

On January 31st, 2026, a day after the Z TriFold was released in the U.S, the phone sold out immediately.[24]

Discontinuation and possible successor

In March 2026, Samsung announced that the Z TriFold sales would end in South Korea and the U.S after just three months of its launch.[25][26][27] Despite being the first iteration already discontinued earlier, a successor is currently being developed (rumored to launch in 2027) and is expected to be thinner and lighter.[28]

Samsung describes new features of a second-generation tri-folding phone and explores several modes of use in a lengthy patent filing. The S Pen is also mentioned, along with an explanation of how it might magnetically attach to the frame.[29]

Specifications

Design

The Galaxy Z TriFold features an aluminum frame, similar to the Galaxy Z Fold 7.[30] It was only sold in a single color option, Crafted Black (just like the Galaxy Z Fold SE).[31]

Performance

It comes in a sole 16 GB RAM option,[32] with internal storage options having either 512 GB or 1 TB.[33] Just like the Galaxy Z Fold 7, it is also powered by the Snapdragon 8 Elite chipset.[31]

Displays

The Galaxy Z TriFold features two Dynamic AMOLED 2X 120Hz displays, one of which is tri-foldable,[32] and adopts a 4:3 aspect ratio when unfolded.[34][35]

When unfolded, the phone is 10.0 inches with a screen resolution of 1584×2160, and measures approximately 159.2 × 214.1 × 3.9-4.2 mm.[32] When folded, the phone is 6.5 inches with a screen resolution of 1080×2520, measuring approximately 159.2 × 75 × 12.9 mm.[32][36][37]

Battery

The battery of the Galaxy Z TriFold is 5600 mAh, the largest battery capacity seen on a foldable Samsung phone.[32][38] The phone has 45W wired charging, which is new for foldable Samsung phones.[32] Samsung claims the phone can charge to 50% in 30 minutes with a 45W cable.[39] The phone also supports 15W wireless charging and 4.5W reverse wireless charging.[32][40]

Camera

The camera hardware of the Samsung Galaxy Z TriFold is the same as the Galaxy Z Fold 7.[32][41][42]
