Sawet Hawk , via OnePlus 9 , Dec 9, 2021 : After update by Oxygen updater the OS change to incremental Os. How I can get back to Oxygen Os again? It doesn't have point for update by myself.
Liehjan , Dec 9, 2021 : What is Incremental OS? If you haven't installed any custom ROM, then it's still running OxygenOS.
Sawet Hawk , via OnePlus 9 , Dec 9, 2021 : I did it by Oxygen updater but the setting system select automatic change to Incremental Os stable.
Liehjan , Dec 9, 2021 : The Incremental means that it's just fetching the OTA file from OnePlus servers. And full means that it's the full zip... You are running the latest version of A12 OOS build C36, and everything is fine so nothing to worry about.
