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.”.
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. 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.S. Or EU retail launch.
Product notes on the same company piece — attribute.78-inch display; 90W wired and 50W wireless charging. Full-duplex means both sides can talk without waiting for a turn.
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. 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.
