I updated to KitKat 4.4.2 on my lenovo yoga tablet. I noticed a big pale smiley on the left end of my system bar which sporadically appears for a few seconds, thrashes àway like mad. I googled and found nothing except a post where a change of google password followed by a factory reset was suggested. I did this, but in doing so lost the post and can't find it again. The ghost reappeared yesterday after a week and a few apps added from google play. Is this friend or foe?
