In addition, copy and paste have also been upgraded. If the app supports a direct copy and paste of images, then Android 11 supports pasting pictures directly into the reply of the app, reducing the need for users to cut between multiple apps. Supported.
4.Privacy and permissions
Android 11 adds one-time permission for location, microphone, and camera permissions. In other words, an app that has obtained one-time permission will still ask the user to obtain authorization when it is next used.
Android 11 will also automatically block repeated permission requests from the app. If the user clicks twice to deny authorization, the system will automatically stop asking for authorization. Of course, the user can also manually adjust it in the settings.
The screencast appeared in an earlier version of Android 10 but was later deleted, but now it can be seen and used in Android 11.

Android 11 also has an upgrade change for the Pixel 4 series, which provides new Motion Sense gestures that can pause music.
