Google 昨天为 Android 11 推出了 Developer Preview 2.1 版本，今次是一个 Minor Update 主要是修正一些之前 DP2 遇到的问题。
General
– Fixed an issue where a crash would occur when long pressing to select an element within the recent apps overview.
– Fixed an issue where the status bar could crash in the background if its components weren’t all initialized yet.
– Fixed an issue where too many WindowTokens were created by SystemUI causing jankiness and dropped frames when navigating and scrolling apps.
Apps
– Fixed an issue where the Wear OS app could crash when trying to pair a Wear OS device.
– Fixed an issue where the Settings app could crash after tapping the search bar in the app.
现在 Developer Preview 仍只向 Pixel 2/XL, Pixel 3/XL, Pixel 3a/XL, 和 Pixel 4/XL 装置提供。由于仍是早期开发阶段，所亾不建议一般用家安装作日常使用。
