After that, four monthly beta releases were planned, beginning in May, the last one of them reaching platform stability in August, with general availability coming shortly after that.[11]

The second developer preview was released on March 17, 2021,[12] followed by a third preview on April 21, 2021.[13] The first beta build was then released on May 18, 2021.[5] It was followed by beta 2 on June 9, 2021,[14] which got a bugfix update to 2.1 on June 23.[15] Then beta 3 was released on July 14, 2021,[16] getting a bugfix update to beta 3.1 on July 26.[17] Beta 4 was released on August 11, 2021.[18] A fifth beta, not planned in the original roadmap, was released on September 8, 2021.[19] Android 12 stable got released on the Android Open Source Project on October 4,[1] getting its public over-the-air rollout on October 19, coinciding with the launch event for the Pixel 6.[20]

Android 12L[]

In October 2021, Google announced Android 12L, an interim release of Android 12 including improvements specific for foldable phones, tablets, desktop-sized screens[21] and Chromebooks, and modifications to the user interface to tailor it to larger screens. It is planned to launch in early 2022.[22][23] A developer preview of 12L was released in October, with three monthly Beta releases planned set starting on December, and the final release scheduled for March.[24]

User interface[]

Android 12 introduces a major refresh to the operating system's Material Design language branded as "Material You", which features larger buttons, an increased amount of animation, and a new style for home screen widgets. A feature, internally codenamed "monet",[25] allows the operating system to automatically generate a color theme for system menus and supported apps using the colors of the user's wallpaper.[26][27] The smart home and Wallet areas added to the power menu on Android 11 have been relocated to the notification shade, while Google Assistant is now activated by holding the power button.[26]

Android 12 also features native support for taking scrolling screenshots.[26][28]

In addition to the user interface, widgets on Android 12 are also updated with the new Material You design language.[29]

Platform[]

Performance improvements have been made to system services such as the WindowManager, PackageManager, system server, and interrupts.[26] It also adds accessibility improvements for those who are visually impaired.[26][28] The Android Runtime has been added to Project Mainline, allowing it to be serviced via Play Store.[28]

Android 12 adds support for spatial audio, and MPEG-H 3D Audio, and will support transcoding of HEVC video for backwards compatibility with apps which do not support it.[28] A "rich content insertion" API eases the ability to transfer formatted text and media between apps, such as via the clipboard.[28] Third party app stores now have the ability to update apps without constantly asking the user for permission.[30]

Privacy[]

OS-level machine learning functions are sandboxed within the "Android Private Compute Core", which is expressly prohibited from accessing networks.[26]

Apps requesting location data can now be restricted to having access only to "approximate" location data rather than "precise".[26] Controls to prevent apps from using the camera and microphone system-wide have been added to the quick settings toggles. An indicator will also be displayed on-screen if they are active.[26]
