The company's Australian arm said in a statement that the update, based on Android 11, included improvements to personalisation, security and privacy, and system and launcher settings.
One feature the company highlighted was the ability to share personal hotspots with others via a QR code.
Commenting on the new UI, realme Australia managing director Andy Yang said: "As a business, our mission is to provide the best pound-for-pound consumer technology experience on the market.
The new UI will be rolled out in stages, and is available right now for the realme 7 5G and X3 SuperZoom.
Users of the realme 7 Pro will get the upgrade in August, followed by the realme 6 and realme C21 devices in the third quarter. Other models, such as the realme C3 and realme C21, will also receive upgrades but the exact timetable is yet to be announced.
