The NFC symbol does not show up also in my tablet. However it transfers files quite easily to my Nokia C7 using NFC. Couple of things which may help you. NFC has to be on in both devices. and the devices have to touch without the case ( at least in my case). How I did it, ( if you want to test). Open the image file using album app. Touch the recepient NFC device on the back of the tablet - if you have an external case, remove it- where the NFC sign is shown. Hold it for a second or two. the image on the album draws down with a beep and the text "touch to beam" is written on top of the image. Touch the image and voila.. See if this works..
