Interesting. So far the best WiFi application I've come across in a camera is the implementation by Olympus EM1. My wife and son use that seamlessly with their Samsungs for transferring images and controlling the camera. My wife will often puts the camera on mini tripods with LEDs on other mini tripods for product shoots. Sony, through the Play Memories mobile App is not any better than WMU on the D750. Since I do not really use the feature , I have not paid much attention. What is obvious is the battery drain

That said, I attended a Company launch event last month. The young, paid photographer was using his D750, 50 1.4D to cover the event for a local Newspaper. We were chatting about the D750 and transferring the images to his paper. He was lightning fast at moving the images to his phone and the moving the image to the Paper's Instagram. For example purposes he did not try and do any in camera editing. He then used his network's 4G to send the image. Unfortunately, as I was about to ask him questions, the VVIPs started arriving .
It appears Nikon did not sort out the Apple arrangement prior to launching Snapbridge and of course, Apple sues every one
