isn't Android supposed to better at networking? and multitasking?
( The iPhone6 Plus was better than the Samsung S6 Edge too so there appears to be a pattern here :-) ! )
The iPhone6S plus pairs very quickly with Fuji's Cam Remote. The Huawei Nexus 6P didn't; it was noticeably slower and more awkward. Huawei's fault? Android's fault? Google's fault? Who knows but it just goes to show . . .
