Android 12 will start being used in smartphones in the second half of 2021, and Android 12L is currently in beta testing, with this version optimized for large-size devices such as tablets and foldables. In addition, Android 13, code-named "Tiramisu", is currently in beta, and tech media @XDA-Developers revealed screenshots of earlier builds of Android 13.
Android 13 will introduce a new feature codenamed "Panlingual" to enable languages for an app in addition to the system's common language, primarily for users who use multi-Chinese. For example, select Chinese in system settings, but when using some apps, you can select a different language, such as English. The Language and Input menu is multilingual for users to give users more choices, and this menu is also accessible through the App Info screen.
By default, any app installed on Android will send notifications as you please. But in Android 13, future notifications could become an opt-in feature where apps can't send spam notifications to users without their consent. As you can see from the screenshot, Notifications is listed as a permission that can be denied or allowed, and this permission can even be revoked after a certain period of time.
While there are some notification settings that prevent this from happening, not all users are aware of the feature's existence. If a user installs the Tacco Bell app, android 13 systems may ask the user if they want to receive a late-night craving reminder.
The layout of Android 13's lock screen clock will also change. Compared with the Android 12 system, the clock becomes a "two-line" layout, which becomes a single line when a notification appears; But Android 13 can disable the two-wire clock layout completely.
Android 13 is currently in the early build stages, and the final feature list changes even before the developer preview starts. This change usually happens after Google I/O (usually sometime in May).
