China: buyers of the ByteDance/ZTE Nubia M153 report WeChat, Alipay and Pinduoduo login lockouts, stopped Alipay payments and a 10-minute game ban after using the Doubao phone assistant to operate apps for them
ByteDance released the technical preview of its Doubao Phone Assistant on 1 December 2025 on the ZTE Nubia M153, an assistant that operates other apps on the user's behalf. On 3 December, 36Kr reports that users in the Nubia M153 user group said WeChat quit unexpectedly and could not be logged in again after they used the assistant to send messages and red envelopes, and The Paper (via Wallstreetcn) reports that users confirmed WeChat crashes and login failures. 36Kr also reports users seeing an 'abnormal login environment' prompt on Alipay, Alipay purchase tasks stopped midway, a 10-minute ban from a mobile game after the assistant played for a user, and Pinduoduo accounts that could not log in on the phone after the assistant was used to browse videos for coins. WeChat told The Paper it took no special action and that existing risk controls may have been triggered. ByteDance took the assistant's WeChat operation offline, said blocked WeChat accounts would be unblocked one by one, and, according to Nikkei Asia as relayed by Business Standard on 8 December, announced a temporary suspension of gaming, banking and online payment functions. The reports rest on user statements relayed by media, and the number of affected users is not stated.
