Not only does Android get a big yearly firmware update, but there are smaller monthly updates, as well. Google Play Security Updates are one of these, but they’re different from the monthly security patches—here’s what they do.

Android不仅会获得大量的年度固件更新，而且还具有较小的每月更新。 Google Play安全更新是其中之一，但与每月的安全补丁不同，这是它们的工作。

Google Play System Updates were introduced in Android 10 (originally known as Project Mainline). It’s mandatory for all Android 10 or newer devices to include Google Play System Updates. While phone and tablet manufacturers are responsible for delivering security patches, Google sends out the Google Play System Updates.

Google Play系统更新是在Android 10(最初称为Project Mainline )中引入的。 所有Android 10或更高版本的设备都必须包含Google Play系统更新。 手机和平板电脑制造商负责提供安全补丁，而Google会发送Google Play系统更新。

With Android 10, Google took 12 core components and spun them out as “modules.” Google can now address these modules independently, without sending a full firmware update or involving the phone manufacturer.

在Android 10上，Google采用了12个核心组件，并将它们作为“模块”分离出来。 Google现在可以独立处理这些模块，而无需发送完整的固件更新或涉及电话制造商。

Google Play System Updates mainly address security issues, but they aren’t the same as the monthly security patches. Both are responsible for different things. All devices with Android 10 and higher can get a Google Play Security Update, regardless of whether they have the latest security patches.

Google Play系统更新主要解决了安全问题，但与每月的安全补丁不同。 两者都负责不同的事情。 所有具有Android 10及更高版本的设备均可获得Google Play安全更新，无论它们是否具有最新的安全补丁。

A good example of where Google Play System Updates could have helped was the Stagefright security bug in 2015. Stagefright was an attack on a multimedia player component in Android. The media framework is one of the 12 components that can be updated through Google Play System Updates. Many devices were never patched to protect against Stagefright because it required a firmware update.

2015年的Stagefright安全漏洞就是Google Play系统更新可以提供帮助的一个很好的例子。Stagefright是对Android多媒体播放器组件的攻击。 媒体框架是可以通过Google Play系统更新进行更新的12个组件之一。 从未对许多设备打补丁以防止Stagefright，因为它需要固件更新。

That’s the most important thing about Google Play System Updates: they don’t require firmware updates or phone manufacturers. This doesn’t mean Google can completely bypass your phone’s manufacturer and bring you the latest features right away. However, it does mean you won’t have to worry about some more critical security issues.

关于Google Play系统更新，这是最重要的事情：它们不需要固件更新或电话制造商。 这并不意味着Google可以完全绕过您手机的制造商，并立即为您带来最新功能。 但是，这确实意味着您不必担心一些更关键的安全问题。

To check your Google Play Security Update version or for a new update, swipe down from the top of the screen (once or twice, depending on your device’s manufacturer). Then, tap the Gear icon to open the Settings menu.

要检查您的Google Play安全更新版本或是否有新更新，请从屏幕顶部向下滑动(一次或两次，具体取决于设备制造商)。 然后，点击齿轮图标以打开设置菜单。

Tap “Security.”

点击“安全性”。

At the top of the screen, you’ll see a “Security Status” section. If the Google Play System is up to date, its icon will be green. You’ll also see the date of the most recent update. If the icon is red, you might need to reboot to install the update.

在屏幕顶部，您将看到“安全状态”部分。 如果Google Play系统是最新的，其图标将为绿色。 您还将看到最新更新的日期。 如果该图标为红色，则可能需要重新启动才能安装更新。

To manually check for an update, tap “Google Play System Update.”

要手动检查更新，请点击“ Google Play系统更新”。

Tap “Check for Update.”

点击“检查更新”。

Note that the “Security Update” and “Google Play System Update” won’t necessarily have the same date.

请注意，“安全更新”和“ Google Play系统更新”的日期不一定相同。
