At the 2026 Mobile World Congress in Barcelona, the spotlight was not only on foldable screens and satellite communication, but also on a preview version of a phone called "M153Doubao AI Phone," which became the focus of controversy. This hardware, jointly developed by ByteDance and ZTE, demonstrated an impressive level of cross-app automation with its ability to deeply integrate into the system's core. However, this near "God's eye view" operation mode quickly sparked a debate among tech experts.

According to on-site reports, Tencent CEO Ma Huateng expressed great caution when commenting on this product, publicly raising concerns about its security. The core of the controversy lies in the fact that the Doubao AI phone needs to obtain high-risk permissions within the Android system to handle tasks across apps like humans. This means that the AI can not only see your screen, but also click buttons and retrieve data on your behalf. Is this "overstepping" operation a tool for improving efficiency or a privacy black hole lurking deep within the system?

In response, Doubao emphasized that all operations strictly followed user authorization. However, according to compliance experts, the situation is not that simple. When AI starts to "take over" the phone across apps, it involves not only the risk of privacy leaks, but also the potential to touch the interests of other app platforms, leading to conflicts between data security and platform openness.

The attempt led by Beijing Chuntian Zhiyun Technology Co., Ltd. (the main entity of ByteDance's large model) actually touched the "no man's land" of mobile phone innovation in the AI era. In the future, the intellectual property system, protection methods, and ecological governance of AI phones will need to find a new balance between innovation efficiency and user safety.

The case of Doubao phone is like a mirror, reflecting the collective anxiety of the industry in pursuing "system-level intelligence": before we completely hand over our phones to AI assistants, who will guard our digital boundaries? This stir in the underlying ecosystem has just begun.
