Xiaomi has officially joined other smartphone manufacturers in releasing an Android 17 developer preview, with initial availability limited to three devices: the Xiaomi 17, Xiaomi 17 Ultra, and Xiaomi 15T Pro. Support for other models is expected to come in the future.
The Android 17 developer preview build is based on HyperOS 3.3. Yes, Xiaomi has surprised everyone by skipping HyperOS 3.2 and releasing HyperOS 3.3 for some unknown reason. This is a notable move, suggesting that the update represents a more significant architectural shift rather than a simple incremental upgrade.
It is worth noting that this update is strictly intended for developers testing their apps in the new software environment. The Android 17 developer preview is based on HyperOS 3.3, meaning the HyperOS 4 release is scheduled for last this year. As this is a very early build, some bugs and known issues are to be expected.
In terms of availability, the developer preview program is live for both Global units and China. Before updating your device, make sure to charge it to at least 30%, and 4GB of free storage is required.
