On Galaxy S3, is there any way to lock or prevent icons from being moved once placed on a screen? My wife is CONSTANTLY moving her icons around (often to a different page!) and she doesn't know how it happens! I NEVER have this happen. I can only suspect that she is pressing the icon to long and accidentally sliding it to it's new location, tho I can't imagine how she would not notice doing so. I was just hoping there might be an icon set-it-and-lock-in-place feature or 3rd party app...any suggestions? Thanks!
