Current Behavior

Clipboard cannot be emptied using empty string / null. The clipboard stays unchanged.

Expected Behavior

The OS clipboard “string” entry should be “cleared” when calling Clipboard.write({ string: "" })

Sample Code or Sample Application Repo

Clipboard.write({ string: "ABCD" });
Clipboard.write({ string: ""});

Reproduction Steps

1. Use the following code to set something in the clipboard :

Clipboard.write({ string: "ABCD" });

1. Paste the clipboard anywhere. Result is ABCD
2. Use the following code to empty the clipboard :

Clipboard.write({ string: ""});

1. Paste the clipboard anywhere. Result should be empty but got ABCD instead

Sorry, I can’t reproduce.

Clipboard is a heap, so it’s not really possible to delete value, it just add a new one on top of the heap, and read return the last one. It’s possible that samsung devices pick the previous value if the last one is "".
