Something is cooking after a new update in my son's S3 (JB 4.1.2) this morning , the very same issue also found in my new S4 (JB 4.2.2). I deactivate the Google Voice Typing from my Language and Input of the setting manual (so difficult to swithch from hand writting and keyboard when the voice typing is switched on....arrrrrh), however it is back to activated after I power down and turn the phone back on. Everything was fine but now it seems some bugs has been introduced. Hope they can fix this soon.... (how can we tell Googles?)
