Got everything copied over from my old phone, the only issue im having is trying to add my own ringtones / alarm sounds. Everytime I hit the add button it tells me I have to go into the settings on my phone to give it permisson to add. Yet I can't find anything in the settings that would allow permission to add them.
Finally found a workaround for at least the alarms. Copy the sound file you want and drop it into the alarms folder on internal storage. Have a feeling that it'll be the same for ringtones. Shouldn't be the solution though since hitting add should work
Best way around this is to go into your Samsung music player, find the track you'd like to use as ringtone or alarm, click ... button at the top right, click set as, then chose alarm or ringtone, done. Hope this helps!
What worked for me was copying the sound from the external folder on my phone and then pasting it to the internal storage ringtone and alarm folder. Otherwise I haven't found an easier solution yet.
