Sony xperia z3 ringtone doesn't change

[TatianaNyc]

I've been trying to change the ringtone to the mp3 file of my choice but it doesn't work. It shows that ringtone is unknown file but still rings as default. I tried copying the file into notifications, no resault. Please help.
Thank you.

Settings-apps-all,tap on 3 dots and reset app preferences.Could you tell where is the mp3 stored?

Also you could download an app such as ringdroid and create your own ringtones (segments of songs)

I have the same problem as TatianaNyc. It shows that ringtone is unknown file but still rings as default and now I cant use settings, sound (application has stopped). I have tried Settings-apps-all,tap on 3 dots and reset app preferences, but still cant access sounds.

Please help.

Check if the same occurs in safe mode:

The same occurred in safe mode, so I decided to make a full reset to original factory settings. After a couple of hours work reinstalling, everything is back to normal. I have also changed the ringtone.

The Ringroid Worked Perfectly. Thanks A Heap. Resetting Apps Preferences Strangley Refused To Work On My Unit But Worked On My Buddy's.
