Yeah I have been wondering where it went. My work got me a Note 5 a few months ago, and I take a lot of pics with it, then want them on my S5 and it takes forever to transfer. Yeah you can use Wi-Fi direct, but it's a pain to setup. I have to make sure I turn on wifi on the receiving phone and then find my other phone and then start it. Most of the time I don't bother and just wait for Bluetooth to work. Unless it is a large file.
I didn't realize that S-beam was something special until I tried having a guy with a LG beam me a video and it took a half hour.
People complain about Samsung and Touch Wiz. But they have a lot of awesome features. I think something went down between Samsung and Google and they had to remove it.
