Originally used to replace widget on Samsung S series phone when built in widget disappeared. Had difficulty at first since when installing only downloads settings icon but not widget itself. Fooled around with it and suddenly the widget started working on phone. It's a great widget working so well on phone I decided to add it to my Samsung Note Tablet 10. Same issue as before. Installed settings icon but no calendar widget even though settings are set to my default calendar. I can't recall how I got widget itself to appear on phone and I'm hardly a mobile device illiterate. Something is wrong when you create an app that doesn't make obvious how to activate full widget. Uninstalled. Waste of space unless you know how to unlock the magic key to get widget itself to appear on screen. Fortunately old widget still working on tablet although it's not as good as one on phone. Going to get new phone soon and wonder what will happen if I try to install this on new device. Useless without widget! Surely I'm not the only one with this issue and nothing on Github.
