Nubia’s new NaviX Ultra smartphone finished complex office tasks 67% faster and with 42% fewer errors than rival AI phones, the company says. It won a SAIL Award for the feat at Shanghai’s World Artificial Intelligence Conference (WAIC) on July 17, 2026. The device runs on ByteDance’s Doubao Mobile Assistant, an agent built to plan trips, compare prices and operate several apps from a single request.
A version of that same idea already ran into trouble this year. A prototype built on the same Doubao partnership sold out fast in December, only for Alibaba, Tencent and JD.com to lock the assistant out of their apps within days.
A Phone Designed to Finish Your To-Do List Without You
“A new era of AI agent smartphones begins,” Nubia said when it shared images of the device online.
Nubia says the NaviX Ultra runs on a native architecture that stitches together environmental perception, intent recognition and task decomposition, so the phone acts on a request instead of only answering it. Most AI features on phones today, things like summarizing texts or cleaning up photos, still wait for a prompt at every step. Nubia is pitching something that chains steps together on its own. Ask it to prepare for a business trip, and the agent is designed to:
- Gather relevant travel information across booking apps
- Organize related documents automatically
- Set reminders tied to the trip’s deadlines
- Complete other prep work without the user switching apps
Nubia frames the build around four goals it calls understanding, functionality, retention and security. Ni Fei, senior vice president of ZTE Corporation and president of Nubia, told Chinese financial wire CLS News Agency that Doubao supplies the large language models and agent skills, while Nubia contributes hardware, manufacturing and after sales work built up since an earlier joint project known as M153. The phone is expected to carry a Qualcomm Snapdragon 8 Elite Gen5 chip and will ship in four color options, though Nubia has not confirmed a display size or battery capacity.
The award recognizing the effort has its own track record. WAIC’s SAIL Award, short for Super AI Leader, has drawn over 4,500 submissions from 20-plus countries since 2018, with past winners including Siemens and Ant Group.
The Same Idea Already Failed Once This Year
The NaviX Ultra is not Nubia’s first attempt at this idea. A limited run of 30,000 units, marketed as the Doubao Phone, sold out fast in December at 3,499 yuan (about $516), and resale prices on the secondhand market doubled soon after.
That prototype could follow voice commands to order food and compare shopping prices across apps. Days after release, Alibaba, Tencent and JD.com restricted the assistant’s access to their platforms, according to Agence France-Presse, effectively disabling the phone’s signature feature. ByteDance had to switch off parts of the tool, including anything involving payments.
Gaining broad access to apps owned by other companies is a sticking point for AI agent devices.
Kiranjeet Kaur, associate research director at IDC (International Data Corporation), offered that assessment in comments carried by AFP.
Cooperation Instead of a Break-In
Nubia appears to have absorbed that lesson. According to Chinese tech media, the NaviX Ultra does not try to force its way into other companies’ apps. It seeks to collaborate with them.
Early hands on coverage describes the device queuing tasks across more than ten platforms, including ByteDance’s own Douyin and coffee chain Luckin, suggesting the agent is starting with willing partners rather than the three that shut it out in December.
Privacy is part of the pitch too. Nubia says core AI computations run locally on the device instead of in the cloud, and that the platform carries official generative AI compliance certification meant to cut the risk of data leaking out. That argument lands amid a broader scramble over data handling. Small businesses are working through their own data privacy basics small business owners need in 2026, and a phone reading someone’s calendar and shopping habits to plan a trip invites the same scrutiny at consumer scale.
Five Straight Quarters of Shrinking Sales
The timing helps explain the urgency. China’s smartphone shipments totaled roughly 66 million units in the second quarter of 2026, marking a fifth straight quarterly decline of 4.3%, per IDC. Huawei and Apple were the rare growth stories, climbing close to 20% and 25% respectively, while rising memory costs pushed most other Android brands to raise prices and cool demand.
The global picture is not much brighter. Worldwide shipments are on pace to fall 13.9% this year, Counterpoint Research forecasts, which would make 2026 the weakest year for the category since 2013.
IDC’s own researchers point at agent phones as one possible way out. Kaur’s team argues that AI agent experiences tying together hardware, software, ecosystem and large models could revive upgrade demand, though probably not before 2028 or 2029.
Honor and StepFun Want the Same Crown
Nubia is not the only company chasing this idea. Honor, the smartphone brand spun off from Huawei, showed a Robot Phone whose camera flips up on a small robotic arm and reads human gestures. Its agent uses AI models co-developed with Alibaba and will ship on new devices later this year, the company told AFP. Shanghai based StepFun unveiled the STEPX Neo, running its own operating system with an agent called Amoo. StepFun chairman Yin Qi said the company struck “deep partnerships” with major Chinese platforms, including Alipay and a ride hailing service, ahead of launch.
| Device | Maker | AI Partner | Distinguishing Move |
|---|---|---|---|
| NaviX Ultra | Nubia (ZTE) | ByteDance’s Doubao | Second generation after a blocked December prototype |
| Robot Phone | Honor | Alibaba (co-developed models) | Robotic flip-up camera reads gestures; ships later this year |
| STEPX Neo | StepFun | Alipay and a ride-hailing service | “Deep partnerships” struck with platforms before launch |
This year’s conference drew more than 1,100 exhibiting companies and upwards of 3,000 exhibits, a new record, and the SAIL Award recognized entries well beyond phones, including an industrial firm’s order splitting and quality inspection agents.
What Nubia Still Won’t Confirm
Plenty about the NaviX Ultra remains open. Nubia has not announced a retail price, an on-sale date or full hardware specifications beyond the expected chipset. The company also has not detailed whether Alibaba, Tencent or JD.com are cooperating this time, or how it persuaded any of December’s holdouts to change course.
- Confirmed: Doubao Mobile Assistant powers the phone under a partnership dating back to the M153 prototype.
- Confirmed: Nubia’s own testing found 67% faster task completion and 42% fewer errors than rival AI phones.
- Confirmed: The device won a 2026 SAIL Award at WAIC in Shanghai.
- Unconfirmed: Retail price and an exact on-sale date.
- Unconfirmed: Full specifications beyond an expected Snapdragon 8 Elite Gen5 chip.
- Unconfirmed: Whether Alibaba, Tencent and JD.com will grant deeper access than they did in December.
Nubia’s wager mirrors a pattern showing up well outside phones this year, with companies betting that AI agents can take over multi-step work end to end. Starbucks, for one, plans to cut $400 million by swapping out Microsoft and IBM software for its own agents, a bet that depends on those agents performing as promised just as much as Nubia’s does.
Frequently Asked Questions
What Criteria Does the SAIL Award Judge?
Organizers score entries on four measures: verifiable technological breakthroughs, proven real world deployment, original approaches beyond incremental tweaks, and impact on long standing industry problems, according to WAIC’s own award materials.
Is the NaviX Ultra Available Outside China?
Nubia has not said. Coverage from the unveiling notes only that fuller specifications, pricing and a launch schedule are expected in the coming weeks, without naming markets beyond the phone’s home country.
Did the NaviX Ultra Win WAIC’s Top Overall Prize?
Not the single highest one. Chinese outlet Sohu reported that this year’s overall SAIL Award, the conference’s top distinction, went to Atlas 950 SuperPod, a Huawei linked supercomputing system, a reminder that WAIC’s AI recognition reaches well past consumer phones.
When Will the Nubia NaviX Ultra Go on Sale?
Nubia has not set a date. The company says fuller specifications and pricing will follow in the coming weeks, with a commercial release expected later in 2026 as WAIC wraps its four day run in Shanghai on July 20.
