I just purchased a LG Optimus Black recently, this is my 1st Android experience and so far so good. I've installed Android system clean which seems to work well but I can't seem to delete the gps navigation history, no matter what I try. I've done a google search and none of the suggestions seem to work with the Navigation app installed. Thanks in advance to anyone who knows how to delete the gps history on this particular phone and posts a reply
