ByteDance launched the consumer edition of Doubao Mobile Assistant on September 14. Compared with the technical preview released in December 2025, the new version upgrades screen interaction, personal information retrieval, agent-based task execution, privacy and security.

The consumer edition will come preinstalled on the nubia NaviX Ultra. Preorders for the phone are now open, with its release scheduled for September 16. ByteDance will also roll out the new version to existing users of the nubia M153.

Screen Content Becomes Task Input

The new version continues to support activation by voice or a dedicated AI button. Fingerprint authentication has been added to the AI button, allowing users to invoke the assistant without unlocking the phone again once their identity has been verified. ByteDance has also improved voice activation for scenarios involving distant speakers, noisy environments and rapid speech.

The screen Q&A feature now goes beyond recognizing and explaining information, using content currently displayed on the screen to complete tasks. In ByteDance's demonstration, users could photograph the interior of a new home and ask the assistant to find suitable cabinets based on the decor, dimensions and budget. After photographing a class schedule, they could ask it to add the courses to their calendar. Users can also edit objects in photos through voice commands.

These scenarios show how smartphone cameras and on-screen content are becoming inputs that help agents understand user needs. However, the results shown in the demonstrations will still need to be validated in real-world use.

Combining Local Search With User-Saved Memories

The consumer edition adds a local search tool. With user authorization, the assistant can search information in photos, text messages and notes stored on the phone, then answer related questions in natural language.

Its recording capabilities have also been expanded to support transcription, real-time translation, speaker identification and summaries of key points, with integration of Feishu Minutes. For example, users can ask about product recommendations mentioned in an earlier interview recording, and the assistant will retrieve the relevant content and organize it into an answer.

Beyond retrieving existing material, users can proactively save information they want the assistant to remember. Voice input, a three-finger upward swipe, or simultaneously holding the AI and volume buttons can all be used to save the content currently displayed on the screen. ByteDance said this content will form a personal memory store that users can search later.

Cross-App Tasks Gain Queuing and Automatic Triggers

For task execution, the consumer edition continues to combine tool calls with graphical interface operations while expanding support for third-party apps. In examples released by ByteDance, the assistant can add medical checkup instructions to notes, book a ride based on an address shown on the screen and add a stop along the route, or send a vehicle's license plate details to a colleague after the user gets in.

The new version also adds task queuing and priority insertion. Users can check task status from the lock screen while continuing to interact with the assistant. Shortcuts allow users to launch preset tasks with brief commands, while automated commands can execute tasks, with user authorization, based on triggers such as a specified time, location or event. Examples include compiling news updates on a schedule or turning on the air conditioner when the user arrives home.

Because these capabilities span multiple apps and devices, their practical scope will still depend on which services are integrated and where user confirmation is required during a task.

Boundaries for AI-Powered Operations Still Need Work

As the assistant gains the ability to access personal information and perform actions, permission controls and security boundaries are becoming critical to its real-world deployment. ByteDance said the new version follows the principle of user control and applies a tiered system to manage the scope of agents' actions.

ByteDance also acknowledged that AI-powered smartphone operations remain a work in progress, with graphical user interface agents, the cross-app ecosystem and task reliability all requiring further improvement. Once the nubia NaviX Ultra launches, the consumer edition's performance in real-world user scenarios will be the key test of whether these upgrades deliver.
