Status on local storage after exporting

When I'm making a new update to my game and install it as a debug APK on my phone all the local storage will still be there. It seems like the game is just installed over the older version so it's not installing it per se. So all my highscores and other settings in the local storage are still there. If I delete the game before installing it will all be gone.

So my question is, when I have finally published my game and make an update to it later. Will all the local storage be unchanged for those updating it from Play Store?

Yes it works as you described - an update does not clear the local data, uninstalling the app will clear the local data.

sweet! :)
