Hi, I know this is an older post. I just got a S10+ and have done just what you wanted. Honestly, the BlackBerry apps work perfectly on this phone. I subscribed to the Hub services and downloaded all the apps. For password keeper you have to create a backup file on the PRIV. After you have the password keeper downloaded on the S10, I just transferred the backup file from the Priv to the S10 using Bluetooth file sharing. Once the download is on the S10, open password keeper and import the backup, enter the password from the priv password keeper and it automatically put everything back in. All in all the S10+ has been awesome. I routinely get 6-7 hours of screen on time and still have 30% battery life left. The Ui on here now is way better than the old touch wiz interface. And the screen is just awesome! All in all I'm happy I went with it. And yes, I went the 1Tb 12G of ram, figured I'll never run out of space and it never lags!
