nubia ships NaviX Ultra — Doubao agent phone on sale from ¥5499

ZTE’s China newsroom said nubia’s NaviX Ultra — framed as the world’s first AI agent smartphone running ByteDance’s Doubao Phone Assistant consumer edition — is formally on sale, with list prices from ¥5999 (¥5499 after China consumer subsidy) across three storage/RAM SKUs on ZTE Mall, JD, Tmall, Douyin, and Pinduoduo.

HARDWARE desk — same-day company primary that a major China OEM handset brand put a Doubao-powered “AI agent phone” into formal on-sale status with public yuan prices, moving the Doubao-on-phone story from assistant/preview talk into a priced shippable device.

Company framing, as the same page has it: “world’s first AI agent smartphone” (全球首款AI智能体手机). Four capability pillars — 听得懂 / 能干活 / 记得住 / 够安全, which the company glosses as understand, execute, remember, and secure enough. The lede says the ship marks the move from an engineering prototype to scaled commercial production, and from stacking AI features onto a phone to a “native agent.” File that first / four-pillar / prototype-to-sale picture as ZTE/nubia’s. This desk did not rank the category or sit through a launch demo.

Pricing, still company: 12GB+512GB ¥5999, or ¥5499起 after 国补 — China’s consumer-electronics subsidy that can lower the sticker at checkout; 16GB+512GB ¥6499; 16GB+1TB ¥7499. First-sale window: up to 24 interest-free installments if the order is placed and paid within seven days of open sale. File those yuan prices and the 7-day / 24-period line as ZTE’s. This desk did not open a cart or confirm a subsidy at checkout. Yuan is China’s currency. A SKU here is a storage-and-RAM combo you can buy.

Channels, company: 中兴商城 / ZTE Mall, JD, Tmall, Douyin, and Pinduoduo. File those named China channels as ZTE’s. This desk is not inventing a U.S. or EU retail launch.

Product notes on the same company piece — attribute, do not overclaim: a fingerprint AI key the company calls the only one in the industry; ByteDance’s Seed full-duplex voice model for interruptible talk; dialect and multilingual support, with the page naming Minnan, Hakka, Shanghainese, Cantonese, and English; multi-step agent task execution, including Feishu messages, meeting booking, and longer locked-screen runs; personal memory with user authorization; a BOE 6.78-inch display; 90W wired and 50W wireless charging. Full-duplex means both sides can talk without waiting for a turn. File those as ZTE/nubia’s. This desk did not time a charge, audit a voice model, or watch an agent finish a task.

Named voice on the page: Ni Fei (倪飞), president of ZTE’s terminal business and of nubia. He says the line from the 2017 nubia Z17 AI phone through the M153 AI-native phone to today’s NaviX Ultra production ship confirms the agent-phone direction. File the name, title, and that direction line as his, via ZTE. His other quotes are color only and stay in Sources.

Plain English for the rest of the card: GA / 正式上市 = shipping and buyable now in the named China channels, not a preview. Doubao = ByteDance’s consumer AI assistant brand. 国补 = China’s consumer-electronics subsidy that can cut the sticker price. agent phone = a handset pitched so the assistant can run multi-step tasks, not only chat. full-duplex = both sides can talk without waiting for a turn. SKU = a storage-and-RAM combo you can buy. yuan / ¥ = China’s currency.

PRIMARY here: ZTE China’s 16 Sep 2026 newsroom page 20260916C1 — Tier A PRIMARY company source, the original record. The formal on-sale / 正式上市 line, the “world’s first AI agent smartphone” company frame, the 听得懂 / 能干活 / 记得住 / 够安全 pillars, the ¥5999 / ¥6499 / ¥7499 list prices and ¥5499起 after 国补, the 7-day / 24-period interest-free window, the ZTE Mall / JD / Tmall / Douyin / Pinduoduo channels, the fingerprint AI key, Seed full-duplex voice, dialect and multilingual support, multi-step agent tasks, authorized personal memory, the BOE 6.78-inch display, 90W wired / 50W wireless charging, and the Ni Fei title are company-attributed. Capability slogans, “industry only,” and “world’s first” stay company-attributed — not independently audited here. NOT claimed: U.S. or EU retail availability, independent latency or accuracy tests, unit sales, ByteDance investment or revenue figures, that this desk tested the NaviX Ultra, a stock tip, or investment advice. Distinct from the already-filed doubao-phone-assistant, xgrids-lixel-l3, agility-digit-5, and universal-robots-gen7-physical-ai. Do not refile doubao-phone-assistant.
