Currently trial version of Color OS 7 is rolling out on all oppo & realme mobiles.
Being a trial version, it has many flaws.
I am using Oppo Reno 10x zoom and I am facing a lot of problems due to the update on the trial version.
I would advise all Oppo & RealMe users not to update the trial version. Wait for stable update of Color OS 7.
Oppo A1k didnot got android 10 or ColorOS 7
It was new model,but also they did not released android 10 updates.Even now from 6 months monthly security patches updates also stopped.
