Finally, in June 2019, Oppo started rolling out the ColorOS 5.2 update, which is based on Android 8.1 Oreo, for the Oppo F5. The update was initially released in India and other countries, and it's expected to roll out to more regions in the coming weeks.

While there was significant anticipation for an Android 8.0 Oreo update following its 2017 release, OPPO did not officially roll out a major OS upgrade to Oreo for this specific model.
