True, but the hardware inside the Apple was designed for streaming video as was their Lightning cable. The Samsung gets bogged down in streaming speed with all the junk it runs in the background. If USB-C was involved then maybe along with a lot better- make that cleaner- running operating system then maybe, but not with USB-mini and their sloppy OS as it is. You want to run an app that requires a lot of processing like DJI Go and video streaming, then good luck with Samsung. If they'd stop allowing every app maker full control of sundry resources it might not slow their products down. But now we get Samsung Pay pop-ups, some other Samsung app installed today too doing what?, Facebook that cannot be uninstalled in the S6, etc.
The Samsung is just packed with a lot bloatware and the bottlenecks in speed are likely buried there. If they'd clean up their OS, quit allowing any app to run within it 24/7 without a Forced close (as well as a re-starting later on of it too), it might work better for streaming. But if they continue to pack it with too much superfluous junk running, then speeds out of it are going to be dismal compared to the Apple iOS that runs with far less bloat as demonstrated by their better battery life too. I was not a fan of Apple, but I can see why they can run far more efficiently with even a lower processor speed since they do not allow for bloat like Windows/Android where both of those OS's run slower over time due to bloat building up. Sort of like when a new install of Windows runs quickly and smoothly, and then in a year or two it gets slower.
My Samsung tablet, a year old, now will take about 5 seconds to press on an icon to do something once left on for an hour or two. Seriously, I could crash a drone in the time it takes to respond now. If I restart it, its instant so the bloat internally is building up over time left on and slowing the device down. Streaming speeds degrading goes with it too.
