The second round of global testing starting on September 17 will add four new models: Mi 17T Pro, Mi 17T, Mi 15 Ultra, and Mi 15. In the future, the list of devices participating in global testing will be significantly expanded.
The company has already begun recruiting the first test participants for the device. This resource advises that places may be limited, so those wishing to attend must submit their application as early as possible GizmoChina. If the application is approved, users will receive OTA Beta updates.
It should be noted that beta versions may contain errors and omissions. It is also recommended that you back up your data before updating your smartphone to the HyperOS 4 beta. However, to go back to the previous version, you need to refresh the device.

HyperOS 4 gets several updates, including a new soft-glass visual design, enhanced home screen customization options, faster app launch, and improved artificial intelligence capabilities.
The HDR processing algorithm has also been updated, making the camera app faster and more responsive. The company also noted improvements in movie playback and overall comfort when using the device.
