This error took me several days head on my smartphone LG Android.
I do not know if it happens in other smartphone, but at least in mine that error occurred by chance combination of keys pressed by mistake or something. The fact is that since I came out, would not let me write anywhere, for example whatsapp, facebook messenger or the like.
As the error trying to write something jumping !.
I looked all network forums, I always out similar errors, but he did not, which is why I wrote in the post title as it appears to me, that helps.
Well, tired of searching and no alternative but to find me living by myself, I began to navigate the menus until I figured it must be a keyboard error and I agreed to that menu.
At least in my LG it is:
MENU / SETTINGS / LANGUAGE AND KEYBOARD
And it was there !, check: Google Voice Dictation marked.
It was clear it and the error disappeared.
I must also say that I have returned to access the menu and the option has again set alone ... but hey, the fact is that has been fixed.
For this to happen to them here is the solution.
