Oppo has ColorOS which is based on Android OS, and it is super efficient android based OS. The OEM has dropped regular software updates for its devices, and even older devices get longer duration support.

This new software update of Oppo A3s is based on Android 8.1 with ColorOS 5 with improvements in performance and stability of device.
OTA drops into devices as it works and if you still have not downloaded the OTA download it manually by going to Oppo A3s’s Settings > Software Update. I would recommend updating over Wi-Fi because it will consume data otherwise.
Last security update for Oppo A3s was introduced back in May i highly recommend you getting this update installed on your phone.
