I think if you purchased the next Launcher or next Launcher 3d Launcher that the themes should be free and ad free. There are ads inbeded in some of these themes that mess up your phone and lock you out of your phone and Verizon has to get the phone back working properly. There's one that locks you out of your phone and you have to pay money get your phone back. I'll copy and paste done of the info that I have when I reply to your email
