Realme UI 3.0 open beta announced for Realme X3
Realme has announced the Android 12-based Realme UI 3.0 open beta program for the Realme X3 in India, which was launched in June 2020 with Realme UI based on Android 10. Those interested in getting a taste of Android 12 and Realme UI 3.0 on their X3 can apply for it by navigating to their smartphone's Settings > Software Update menu, then tapping on Trial version > Apply Now, and submitting the required details. You will receive Realme UI 3.0 if your application is accepted.
But do note that since this is a beta build, it may have bugs that could hamper the user experience, so it's best avoided on your primary device. If you still want to give it a try, make sure your X3 is running firmware with version RMX2081_11.C.13 or RMX2081_11.C.14 and has at least 60% battery and 5GB of free storage before installing the open beta update.
