My ringtone keeps going back to current theme iafter 6 hours or so when selecting something else for my ringtone. I did download a new theme from the theme store recently but I download themes all the time and this has never happened before. I've been able to select other ringtones for the themes that I use from the store. I use Zedge for the ringtones and even download them and put them in the ringtone folder for the internal. But for some reason it keeps going back to current theme ringtone. Any suggestions?
