Xiaomi has quietly started internal beta testing of HyperOS 3.0.34.0 for the Xiaomi 17 Pro series and it aims to make the phone’s secondary rear display more useful.
The update, which ranges from 568MB to 1.2GB depending on the device, is being rolled out in phases via Xiaomi’s improved HyperOS 3 OTA logic. Priority is given to users who frequently check for updates, and new batches are sent every 1-2 days. As always with Xiaomi’s grayscale strategy, manual checking often guarantees earlier access.
The update enables a new custom wallpaper feature for the rear screen of the 17 Pro and 17 Pro Max, called “Sugar Cube” (translated from Chinese), which supports live photo and even video formats. It is described as a “fun wallpaper for your back screen.”
Other improvements to the back screen include a three-finger swipe down gesture for screenshots (with multiple styles and screen cover support), one-click saving of newly generated AI wallpapers to the album (requires Themes & Wallpapers app version 10.5.7.5 or higher), and new IP and 3D anime wallpapers added to the Theme Store specifically for the back screen.
Beyond the fun additions, the update brings practical improvements:
- Optimized gaming performance
- Fixed network compatibility issues causing abnormal calls.
- Resolved occasional static noise during screenless music playback.
- Fixed abnormal probability display bugs
- Improved camera image quality, shooting fluidity and overall stability
While the update is currently in internal beta and arriving on devices gradually, the combination of performance fixes and the undeniably interesting “Sugar Cube” custom wallpaper gives Xiaomi 17 Pro and 17 Pro Max owners something new to look forward to this holiday season.
