TL;DR
- Android 16 introduces “seamless app updates” to make installing app updates faster and less disruptive.
- This feature significantly reduces the time an app is frozen during an update, cutting it from seconds to milliseconds.
- The improvement is achieved by running optimization scripts earlier in the installation process, reducing app downtime.


This process was not started until the app was frozen until android 16. This added a few seconds to every app install.
