Google 刚推出了 Android 12 Beta 2.1，这次主要是针对 Beta 2 中的一些问题作出修正。
在 Android 12 Beta 2 中，有一些影响到日常运作的问题，例如在 Lock Screen 不能扫走通知, 不能向上扫解锁，今次在 Beta 2.1 中就修正了这问题。另外还修正了 At a Glance Widget 中欠缺了天气和行事历活动资料。除了上述两个操作问题外，Beta 2.1 也修正了当在手势导览开启 Recent Apps 画面时，出现闪烁动画效果情况，另外还修正收音咪和相机权限提示显示问题, Android Emulator 连接网络问题以及重设装置时设定导览问题。
由于是小型修正，所以 OTA Update 下载档案也很细小，只有几至十几 MB，视乎不同 Pixel 装置。各位有安装 Android 12 Beta 版本的，可以在装置内检查更新跟着下载安装。下面是 Android 12 Beta 2.1 Release Notes
