On Android, when you touch some text, you get handles below the text that serve to move the cursor and selection. They also show up when interacting with the on-canvas text tool input, but attempting to manipulate them does nothing.

Manipulating the singular cursor if no selection is present and the right handle of a selection doesn't even send any input method events as far as I can tell. Manipulating the left handle of a selection does trigger input method events, but their contents are garbage. On top of that, the text tool ignores any input method events that don't contain text inputs, so it wouldn't act on the events either way.
