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 you . . .
Don't buy the companies Google. Instead fly them to Mountain View for 1-4 months and fund them to get their Android-only RAW camera (only Android has RAW APIs; iOS doesn't; Windows Phone does but nobody it breaks my heart to say it cares about Nokia er Microsoft phones and Windows Phone) apps as awesome as possible on Nexus 6, Nexus 5 . . .
