Realme has opened the Early Access program for realme UI 3.0 and Android 12 for the GT Neo2.
There are a few steps that attendees need to take, such as backing up their phone, updating system apps, and securing at least 10GB of storage. From there they need to go to the System Update menu and from the options choose the Trial menu and sign up for the Early Access program.
As this is a beta version of the software, Realme does not encourage you to install it on your primary phone. There are probably more than a few bugs. But there is a fairly straightforward rollback step for those who want a return to realme UI 2.0.
Realme UI 3.0 bring a redesign and a myriad of features, not to mention the upgrade to Android 12.
