I have an iPhone 6 and a Samsung phone, it makes me crazy every time when I want to transfer the contacts or pictures from the Samsung to the iPhone. I also usually used the way of microsoft account to synchronize the data before. But since I found a software which is called iSkysoft Phone Transfer, it is easier to sync the data(including music , video ,contacts,etc) between two different phones with i click. Maybe you can have a try, best regards.
