I have a Samsung S6 but very disappointed with the user interface after using iOS for some years. It's not intuitive or consistent and many things just don't work. For example, I have followed the process to change the ringtone from Over The Horizon to a different one. After tapping the button for the different one and then tapping Add Ring tone I get presented with Sound Picker. It shows several music options and also the Over The Horizon option I wanted to change from. Mad! Before I removed it Add Ringtone went to DropBox. Even madder. What's going on!
