Google will release some security updates from their play store with Android version. Such updates will be installed faster in device devices.
At this time it takes a lot of time to issue Google’s security updates and send updates to Samsung and LG devices such as phone manufacturers. It can take a lot of time to do all the updates for all updates.
But with recent changes, Google will be able to better secure security updates.
Google has projected the project as Project Mainline and it will be part of Android. This will enable Google to release some security updates directly on the phone via the PlayStore. This means that all Android devices from outside of China will benefit from this feature of Android. Play Store is not installed in Chinese Android smartphones.
Google will not be able to update everything in this way. Yes, Google will be able to exclude small troubles.
