Are you trying to find an app for downloading ringtones? Is it a specific ringtone you are looking for? What are you trying to use to download ringtones? If you could give some detail as to what you are doing/ trying to do, I might be able to help.
Hi Cuddles, can you try to download the mobile application 'zedge' from the playstore? It's a great app for wallpapers and sounds. It will offer you to use the ringtone right away once it's downloaded.
