Security updates until 6 March 2032 (OPPO UK list entry "OPPO A6x")From OPPO's UK product security update period list. The list separately names an 'OPPO A6x 5G' with a different date; the UK A6x (CPH2819) is the 4G model. No Android version-upgrade count is published. OPPO's '48-Month Fluency Protection' claim applies only to 256 GB or larger models, not this 128 GB configuration.
