I just got my s4, previously had a Droid Razr Maxx. First Samsung phone in many years. I had used MultiPicture Live Wallpaper before, but it doesn't work, apparently due to the way Samsung does multiple screens. So - is there a decent multiple wallpaper app that works on the S4? Second topic - S Voice is terrible compared to the Motorola voice dial - still hasn't gotten a name right after probably 20 tries. Any suggestions for training it?
