i am brand new at this , a samsung galaxy tab2 10.1 with android 4. while i was starting to learn to use it, i found the voice dictation to be very useful. unfortunately, the key that had the mic on it has been replaced with one that looks like a portrait orientation document with lines of text and a black box in the upper right corner that probably represents a graphic or photo. the settings show a google keyboard and a samsung keyboard, both with voice turned on. i have tried turning each off in turn and lots of other things. the new button seems to bring up copies of pages i have viewed, but they do not seem to be linked to anything. i deleted all of them but it did not get rid of the button. the utter lack of documentation on this thing is really frustrating. any ideas?
