The problem is in your GS7 then, you need to see if there is a way to fully
purge all app related data when uninstalling the app.

That is the expected behaviour if the app was fully removed.
The differences you are seeing can be related to app signing, if done
properly the official app
and the one you build should throw an error if you try to install them on
the same device at the same time.

Local saved dives will be merged into the active cloud account when you
sync, and will be accessible from other devices using the same cloud

I wonder why you would do that, but it should merge fine since the data
from the DC will be identical.
