Hey there Koabehr, Thanks 4 the info!
But I solved most of the Iphone Tranfere issues to the Galaxy S4.
Here's how: After going around 4 weeks w/ Samsung Advance Support (literally 4 weeks + and they're Still working on the last part of the issue w/ the music).
The Greatest find for these transfer issues:
Got a new LEEF 32gb flash ($32 direct, Amazon only has the 16gb ($18), the 64 gb comes out in a couple weeks) with MIcro AND Regular usb. A miracle maker and quick!
One could just by a $6 adapter, yet this is a larger flash, it's all in one & convenient.
I transfered my exercises, music & work videos, DM free data, files, etc.
Just upload it from your Mac, slid the micro usb plug out and transfer to the S4 via Astro File Manager (free app). BAM done deal.
Wish I knew about this 3 weeks ago, the LEEF would have saved me weeks of hassle in to a 8 minute easy as pie transfer.
