Changing app install location permissions

Question

Suppose my app permits installs to external storage: android:installLocation="auto”.

Assume some of the users have installed the app to e.g. SD card.

For various reasons, in the next update, I want to enforce my app to be installable to internal storage only by updating the permission tag to android:installLocation="internalOnly”.

What would happen to the users with the app installed on external storage after the update?

Answer 1

Nothing will change, only new users will have that applied to them.
