## Versions Tested
Xamarin 22.214.171.124 (a9c7826), Xamarin 126.96.36.1990 (2e39740)
Xamarin.Android 188.8.131.52 (ee215fc), Xamarin.Android 184.108.40.206 (4e27558)
## Steps to reproduce (Screencast below)
1.Open Visual Studio 2015 and create new Android app, File -> New -> Project -> Android Blank App
2.Make sure leave Fast Deployment unticked, Project -> App Properties -> Android Options
3.Build and start debugging the application (New app now copied and installed to device).
4.Stop debugging, close App and start debugging again.
## Expected Results
Build detects that App on device is up-to-date and starts debugging without having to copy and re-install application.
## Actual Results
Build logs show that application is being uninstalled (UninstallPackage pm uninstall -k), copied, and re-installed on the emulator or device.

## Additional Information
Screencast demonstrating the issue: https://monosnap.com/file/jzmsvyajM7pLSp50JzKhKRdermKZOT
Although the issue will disappear if Fast Deployment is enabled, some users will be forced to keep it disabled due to a few Android devices blocking it.
This issue is only observed in Visual Studio and not in Xamarin Studio. The XS build detects the up-to-date version and simply starts the app and starts debugging.
We need Diagnostic Build and Deployment logs in order to investigate this further.
Because we have not received a reply to our request for more information we are closing this issue. If you are still encountering this issue, please reopen the ticket with the requested information. Thanks!
