I use different apps that work with GPS on my device. One of the apps has a "download A-GPS information" button to quickly find satellites.

Does that mean that apps need to trigger the A-GPS download themselves? Or does the Android OS handle A-GPS download whenever GPS is turned on?

    A-GPS data comes pre-loaded with the OS. GPS Toolbox allows you to download specific A-GPS data that has more satellites in your region in it but less for other regions. It works wonders and helps with long TTF's (time to fix)

The OS manage the A-GPS information, but you can ask to force a new data download to update it.

Andorid do it automatically when A-GPS data expires.
