The 2017 provisions set the disclosure, consent, charging, channel and distribution controls. The 2022 notice makes the company that preinstalls an app responsible for it and requires manufacturers to prevent operating-system replacement and unauthorized app installation during product distribution. Apply the duties by role: a terminal manufacturer owns the factory image and channel controls, an app provider owns its app conduct and disclosures, a distribution platform owns review and traceability, and a billing provider owns billing confirmation records.
