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.


Wow I just read a thread about an app update taking 45mins after install. That is nuts.
Disabling JIT on modern day smartphones is too much. It will be like the android 5 Lollipop where apps took a while to install after each update. Plus, the long update cycle. Good riddance, I jumped from that time period.
