Check and clean your clipboard using service, widget, shortcut, and quick setting tile.

Possible reasons for the app failure
1. From Android 10(Q), Non-input-method apps can\'t get, modify, and listen to the clipboard in the background. Although this app tries its best, it still may fail, and the listening to clipboard changes is unavailable for now. Please test the app yourself before use.
2. If you see multiple clips or clip history, it means something like the keyboard app stores them. In this case, this app fails.
