Why do you see OBJ when you post to Facebook from your iPhone?

I've asked this question because I think I've found a workaround, which I hope will be helpful to others. Maybe others have posted this, I don't know.

It seems the [OBJ] small graphic appears, randomly, only when you dictate text, not if you type it.

Here is a solution: Select what you've dictated, then Cut. Then paste it back. This seems to avoid the silly [OBJ] small graphic.

A variation: Dictate the message into the Notes app on your phone. Select what you've dictated, then Cut. Paste the text into Facebook where you want to post.

Really, Apple should fix this. Such a workaround should not be necessary.
