Just to rule out a SD card issue, have you tried installing the Roku mobile app directly to the internal storage of your mobile device?
I would also try performing a network connection reset both on the Android device (Settings/More/Network Settings Reset), and the RokuTV (Settings/System/Advanced System Settings/Network Connection Reset/Reset Connection). This may help to sync everything back up. I probably would just throw in a router reboot as well for good measure.
I have seen a few different postings scattered throughout the forum regarding private listening crashes and Samsung phones, but nothing that is mirroring the details of your issue. (especially with some of the app features missing from the screens as indicated in your screenshot.) Almost looks like a corrupted app that is stuck in memory or cache somewhere.
