NFC Transfer on 4.4.4

[captfbgnet]

Sprint here: with 4.4.2 was able to transfer via NFC files or pictures from one GS5 to another with same OS. With 4.4.4, phones 'beep' but tapping on the screen to initiate the transfer does NOT bring up the transfer screen. Only the dialog screen telling you to tap to bring up transfer screen (which does not happen). Anyone seen this 'quirk' or is there a fix for my phone? Restart or clearing partition cache hasn't worked. All help appreciated.
