OPPO's F11 line of phones are powered by the MediaTek Helio P70, and stands out thanks to its Pro variant with a pop-up selfie camera module. Despite being released in mid-2019, these phones remain on ColorOS 6 based on Android 9.0. Now, however, it appears the OEM has a major upgrade to this OS in progress.
The company has invited F11 series users to take part in a "Trial Upgrade" program, which updates selected units to ColorOS 7. It is open to the F11 and F11 Pro, as well as this phone's Marvel's Avengers Limited Edition.
Users can apply to be part of this beta program via the "Trial Version" menu, which is accessed through the Settings icon on the Software Update page in Settings on OPPO phones. ColorOS 7 for the F11 or F11 Pro adds features such as a "borderless design" for the UI; a new camera interface; a new font (OPPO Sans) and ringtones that change according to the weather.
