[DeletedMember1930430]

Hi whenever I choose an new alarm tone on the pre installed Samsung alarm clock for Samsung Galaxy S3 a few days later it changes back to the default tone (walk in the forest alarm) is there are way to stop this for happening as I always have to change the ringtone everytime it happens and I just want it to be the ringtone I have chosen and not the default one thanks. I forget to include a screenshot but I have just changed it a few minutes ago the post below Is what happened when I turned it on when it was out of battery
