I downloaded and installed Nova Launcher and Polycon Icon Pack from the Google Store yesterday. After using them for awhile, I decided that I did not want them. I went into Sttings->Application Manager -> Polycon and did a Force Stop, Cleared Data, Cleared Cache and then selected Uninstall. I am asked to confirm that I want to uninstall the app. When I confirm, my Ellipsis8 immediately reboots and Polycon is still there. I have the exact same problem with Nova Launcher.
