This is the first Realme smartphone to receive Android 10-based UI update

Realme has rolled out the Realme UI-based Android 10 operating system update to the Realme 3 Pro smartphone. The device is the first Realme smartphone to receive Android 10 operating system.
In a forum post, Realme said that this official rollout is happening in a phased manner and may take sometime to reach all Realme 3 Pro handsets. “The update will be randomly pushed out to a limited number of users today and will have a broader rollout in a few days after making sure there are no critical bugs. If no critical bugs are found, the full rollout will be completed in the upcoming days,” said Realme blog post.
This week only, Realme confirmed the name of custom UI which is based on ColorOS 7 as Seamless Fun UI. This Seamless Fun UI now comes with customisation in terms of icons, wallpaper and animations.
