ByteDance's AI smartphone, the Nubia M153, faces backlash as major Chinese apps restrict its functions over security concerns. In response, ByteDance announced it would limit its AI assistant, Doubao, preventing it from accessing financial services and competitive games. This follows actions from platforms like Alipay, owned by Ant Group, which cited unfair practices. User Chen Tang reported that major apps cannot be operated via Doubao, marking a significant shift in the device's usability and market reception.
