Samsung Electronics announced Thursday that fresh shipments of the Galaxy Z TriFold will arrive at major U.S. carriers and retailers starting October 31. Demand overwhelmed initial supplies, with Verizon, AT&T and T-Mobile websites showing ‘sold out’ notices since the phone’s U.S. debut last week.

The Galaxy Z TriFold features a 9.9-inch primary folding display flanked by two 6.5-inch outer screens, powered by the Snapdragon 8 Gen 4 processor. Priced from $1,799 for the 256GB model, it targets power users seeking maximum screen real estate in a pocketable form. Early sales figures from Samsung indicate over 500,000 units moved globally in the first three days, according to company executives in a briefing to analysts.

U.S. customers who missed the first batch can pre-order restocks now through Samsung.com or carrier portals. Best Buy and Amazon list delivery windows from November 1 through November 5, depending on storage options. A Samsung spokesperson confirmed to reporters that production lines in Vietnam have ramped up to meet the surge, with no delays expected for the holiday season.

Reviews praise the TriFold’s hinge mechanism, which allows smooth unfolding across all three panels for multitasking. Battery life holds up under heavy use, lasting 12 hours in video playback tests, testers reported. Cameras include a 200-megapixel main sensor and dual 12-megapixel ultrawides, matching the Galaxy S25 Ultra specs.

Competitors like Huawei’s Mate XT, launched in China earlier this year, sparked the tri-fold trend. Samsung’s entry, first teased at Unpacked in July, beat expectations with its under-display cameras and S Pen support on the main screen. Analysts at Counterpoint Research project tri-fold devices to claim 15% of the foldable market by 2026, up from 2% this year.

Carriers offer trade-in deals worth up to $1,000 on older Galaxy models. Verizon’s promotion, for instance, slashes the 512GB TriFold to $999 with an eligible swap. AT&T bundles it with unlimited plans starting at $85 monthly. T-Mobile matches with 0% financing over 24 months.

Samsung faced supply hiccups early on, blaming a parts shortage at a South Korean supplier. The company resolved the issue by shifting to alternate vendors, executives said in a supply chain update. U.S. restocks prioritize online orders placed before October 29.

Consumer interest spiked after hands-on demos at New York stores drew lines of 200 people each. Social media buzz centers on the device’s ability to run three apps side-by-side, ideal for gamers and creators. One YouTuber clocked 2.3 million views on a TriFold unboxing video within 48 hours.

Looking ahead, Samsung plans a software update in December adding AI features like real-time translation across screens. The phone runs One UI 7 on Android 15 out of the box, with seven years of updates promised.
