Wow. I'm having similar feelings about Android and was thinking of getting an iPhone 7 when the time comes. Mostly my frustration with Android is that occasionally my Galaxy S6 active just...slows...down...for.........no reason and then it catches up and everything moves too quickly and the wrong stuff happens and and and...
I attribute my frustrations to the AT&T and Samsung bloatware/crapware that cannot be uninstalled. That fact alone explains my longing for iOS, but I also notice that, in general, developers put more effort into their iOS apps than Android. I don't have any plans to use iTunes or any other "play the music on your device" apps so that's not a huge concern.
I'm interested now to go back and look at your earlier posts. As for your iPhone, you could always buy a BlendTec and solve the problem :-).
