Google 今早推出了 Android 13 正式版本，Google Pixel 装置亦开始推送更新。这个消息都有点突然，过往几年 Android 新系统正式版本都是在9月左右推出，上年 Android 12 更是在 10月才正式推出，所以今年一般也预期 Android 13 都是在9月才正式推出。
Google 亦随即向旗下 Pixel 装置推送更新，包括有 Pixel 4, Pixel 4a, Pixel 5, Pixel 5a, Pixel 6, Pixel 6 Pro 和 Pixel 6a。至于 Pixel 3a 装置因为已过了指定的更新期限，所以不会有 Android 13 升级，只继续停留于 Android 12。

新功能和改进
至于 Android 13 升级内容方面，在功能和界面上都不算是大改动。毕竟上年 Android 12 引入了 Material You 界面，亦有多项保安上的改进如 Privacy Dashboard，所以今年 Android 13 主要都是针对之前新功能作出的改进和不少的修正。主要改动包括有 Themed App Icons 可配合桌布颜色，媒体播放器可展示专辑封面并有全新的播放进度杆，可为每一应用程式设定不同语言，控制 Apps 通知发送。
2. For the many Android users who speak more than one language, we’ve added a top feature request. You can assign specific languages to individual apps so you can keep your phone’s system in one language, and each of your apps in a different language.
3. Android 13 features an updated media player that tailors its look and feel based on the music or podcast you’re listening to. For example, when you’re listening to music, the media player spotlights album artwork and has a playback bar that dances as you progress through a song. It even works for media played through Chrome.
4. Your wellbeing has been an important theme for Android – and getting enough sleep is key! Android 13 allows you to further customize Bedtime mode with wallpaper dimming and dark theme. These screen options help your eyes adjust to the dark when you're about to go to bed – and get back to sleep if you wake up and check your phone in the middle of the night.
Keeping you protected and secure
5. Gone are the days when you had to share your entire media library with your apps. In Android 13, you can select only the specific photos and videos they’ll need to access.
6. Prevent any unwanted access to your clipboard. If you copy sensitive data like your email address, phone number or login credentials on your device, Android will automatically clear your clipboard history after a period of time.
7. Android 13 helps keep your notifications under control and makes sure you only get the alerts you ask for. The apps you download will now need your explicit permission to send notifications, rather than being allowed to send notifications by default.
8. Feel like you’re in the middle of the action with Spatial Audio. On supported headphones that enable head tracking, Spatial Audio shifts the source of the sound to adapt with how you turn your head, giving you a more immersive listening experience on your Android phone or tablet.
9. When you’re on your laptop, you don’t want to break your workflow to respond to a chat from your phone. Soon, you'll be able to stream your messaging apps directly to your Chromebook so you can send and receive messages from your laptop.
10. Android 13 adopts Bluetooth Low Energy (LE) Audio, a new Bluetooth audio standard that results in lower latency than classic audio. This allows you to hear audio that’s in better sync with the sound’s source, reducing delay. With Bluetooth Low Energy (LE) Audio, you can also enjoy enhanced audio quality and broadcast audio to multiple devices at the same time.
11. You’ll soon be able to copy content — like a URL, picture, text or video — from your Android phone and paste it on your tablet. Or you can start on your tablet and paste to your phone.
12. Multitasking on your tablet is even easier with Android 13. With the newly updated taskbar on tablets, you can see all your apps at a glance and easily drag and drop any app in your library into split-screen mode.
13. Android tablets will register your palm and stylus pen as separate touches. So whether you’re writing or drawing on your tablet, you’ll experience fewer accidental stray marks that come from simply resting your hand on the screen.

Beta 版本安排
Android 13 正式推出后，相关的源程式码亦放上了 AOSP，即是话 Custom ROM 可跟随开发，相信很快 Custom ROM 就会有 Android 13 版本推出。至于 Beta 版本安排，Android 13 正式版本推出后，下个月开始 Android Beta 就会继续用于推出每季更新 QPR 的 Beta 版本。若果已登记了 Beta Program 的话，9月之后就会收到 QPR 的 Beta 测试版本，若果不想再继续使用 Beta 的话，可以趁现在升级至正式版本时推出 Beta Program，这样就可无伤害地退出，不用洗机。
