Help Request: How to use NFC to receive files?

[tarzanmarzan]

Hello! I tried to use NFC tap and send with my cousin's Nexus tablet previously with my friend's Galaxy III. Unfortunately all I am able to do is send files. It worked when I sent a picture to my cousins tablet, but it sent a string of random letters and a tag to my friend's phone.

Furthermore I cannot receive pictures or files from people. If I can, I have no idea where to find them. Thank you very much for your time and effort with helping me figure out this handy feature. Have a nice evening!
