Xiaomi releases the MIUI 10 Global Beta 9.2.28 which will be available for some of its smartphones with exciting new features and many bug fixes.

New features include Game Booster and persistent screen locking. The Game Booster optimizes the gaming experience with features like auto brightness, screenshot gestures, and Reading mode.

It can be turned on by dragging the screen from the notification bar when a game opens, and also allows automatic brightness to be turned off. Also, a floating call window has arrived, which can be used when a title is occupying the entire screen.

Persistent locking, however, is a small security enhancement so that only the owner of a registered face can view the notifications from the lock screen.

Smartphones which receives the MIUI 10 Global Beta 9.2.28 includes the Redmi S2, Mi Mix 2S, and Mi 6 among others. Due to some issues, the upgrade to Redmi Note 4 and Redmi Note 4X and Redmi 5 Plus has been postponed.

Devices such as Redmi 6 and Redmi Note 6 Pro will receive the update in the coming days.
