Revolutionary Tri-Fold Design
Samsung launches the Galaxy Z TriFold, a trailblazing foldable smartphone with three articulating sections that unfold into a 10.0-inch QXGA+ Dynamic AMOLED 2X main display at 2160 x 1584 pixels and ~269 ppi density, alongside a 6.5-inch 1080 x 2520 cover screen at 422 ppi for everyday phone functionality. This premium device blends smartphone compactness with tablet productivity, debuting in South Korea on December 12, 2025, before expanding to other Asian markets and reaching the US in Q1 2026. At KRW 3,590,400—approximately $2,500 or 2100 EUR—it surpasses the Galaxy Z Fold 7 by about $500, justifying its advanced tri-fold engineering and materials.
Enhanced Armor FlexHinge System
The refined Armor FlexHinge incorporates two variably sized hinges to precisely align the three panels: center at 4.2 mm thick, outer panels slightly thinner, achieving unfolded dimensions of 159.2 x 214.1 x 3.9-4.2 mm and folded at 159.2 x 75 x 12.9 mm. Constructed with Gorilla Glass Victus Ceramic 2 front (folded), plastic front (unfolded), ceramic-glass fiber-reinforced polymer back, Advanced Armor aluminum frame, and titanium hinge housing, it weighs 309 g and earns IP48 rating for dust protection over 1 mm and immersion up to 1.5 m for 30 minutes. Distinct from Huawei’s Mate XT Z-fold exposing main screen edges, the TriFold folds left and right segments inward behind the dedicated cover display, with extensive testing ensuring hinge durability for years of daily use.
Pocketable Yet Powerful Form
Challenging traditional pocketability norms, the TriFold’s 12.9 mm folded thickness and 309 g heft exceed the Z Fold 7’s slimmer 8.9 mm profile but align closely with prior tablet foldables like the Z Fold 6. The tri-foldable Dynamic LTPO AMOLED 2X main screen boasts 120 Hz adaptive refresh, HDR, 1600 nits typical peak brightness (up to 2600 nits), and ~89.6% screen-to-body ratio, supporting seamless three-app side-by-side multitasking in portrait orientation. Full Samsung DeX delivers a wireless desktop experience on-device, perfect for productivity without docks or monitors.
Elite Snapdragon 8 Elite Internals
At its core lies the Qualcomm Snapdragon 8 Elite (SM8750-AC, 3 nm) with octa-core CPU (2×4.47 GHz Oryon V2 Phoenix L + 6×3.53 GHz Oryon V2 Phoenix M) and Adreno 830 GPU at 1200 MHz, running Android 16 atop One UI 8 for fluid performance across the vast display. Memory options include 16 GB RAM with 512 GB or 1 TB UFS 4.0 storage, no microSD slot, and robust connectivity: Wi-Fi 802.11 a/b/g/n/ac/6e/7 tri-band, Bluetooth 5.4, NFC, USB Type-C, dual Nano-SIM + eSIM (max 2 active), GPS/GLONASS/GALILEO/BDS/QZSS, plus sensors like side-mounted fingerprint, accelerometer, gyro, proximity, compass, and barometer. Stereo speakers provide immersive audio, though no 3.5 mm jack is present.
Versatile Triple-Cell Battery
A 5600 mAh triple-cell battery powers intensive sessions, with 45W wired charging reaching 50% in 30 minutes (QC2.0 compatible), 15W wireless, and 4.5W reverse wireless capabilities. While modestly larger than single-screen flagships, the expansive 10-inch display and multi-app workloads may demand frequent top-ups during peak use. This setup balances portability with endurance for on-the-go professionals leveraging DeX or extended viewing.
Flagship Camera Array
The rear triple setup mirrors Z Fold excellence: 200 MP f/1.7 wide (1/1.3″, 0.6 µm, multi-directional PDAF, OIS), 10 MP f/2.4 3x telephoto (1/3.94″, 1.0 µm, PDAF, OIS), 12 MP f/2.2 120° ultrawide (1/2.55″, 1.4 µm, dual pixel PDAF), featuring LED flash, HDR, panorama, and video prowess up to 8K@30fps, 4K@60fps, 1080p@240fps with gyro-EIS and 10-bit HDR10+. Selfie cameras comprise a 10 MP f/2.2 ultrawide under-display (18 mm) and 10 MP f/2.2 wide cover camera (24 mm), both capturing 4K@60fps with gyro-EIS and HDR. The protruding module preserves high-end imaging in the tri-fold chassis.
Global Launch and Availability
Available in Crafted Black, the TriFold (models SM-D639B/DS, SM-D639U, etc.) launches December 12 in South Korea, with swift Asian rollout and US carrier support by early 2026. Its slim 3.9 mm thinnest point and premium build position it as a foldable leader, appealing to power users seeking adaptive screens for work, entertainment, and creativity. Samsung’s tri-fold milestone elevates mobile versatility, promising smoother transitions between phone, tablet, and desktop modes.
Ultimately, the Galaxy Z TriFold embodies Samsung’s vision for future foldables: a pocketable ecosystem shifter with unmatched screen real estate and performance. From cinematic 8K videography to DeX-driven workflows, it empowers users to maximize every inch of display. As tri-folds mature, this device sets the standard for innovative, durable mobile evolution.
