As I have mentioned before! Samsung Smart Switch!
I had about 75 notes on my iPhone 4S. After backing up my iPhone via iTunes, the Smart Switch app automatically picked up the backup and my Note 3
I then clicked everything I wanted to transfer and a couple seconds later all was done!
Can't ask for anything simpler than that...
I used Smart Switch and was able to copy everything over EXCEPT for my notes - I can see notes in the list but won't let me select them. Have tried countless times but no luck at all.
