fussy
Why are people so fussy about smart phones?
A bit of texting, phone calls, probably email, web.
Some phone camera use for rough & ready images (compared to a dedicated camera)
Possibly using mapping app to find your way around somewhere new.
Possibly music listening / TV or other streaming viewing.
Then some random selection of apps, anything from twatter, facebook through to useful things.
I have used a variety of phones & it's no real hassle to get used to quirks of a particular phone be it Apple, Android or whatever, so long as the apps you require are there & phone stable enough that it it does not crash frequently / battery lasts a while.
I'm more bothered about dual SIM, sd card expansion & removable battery than the OS (though obv those requirements tend to preclude apple as a first choice, though I do use iphone as a spare in case of breakage / theft of main android phone (iphone was one of my partners "cast offs" after upgrade, not cutting edge but it is sufficient for my needs))
Most people have enough important things going on in their life to not be overly bothered about presence or absence of some particular gestures on a phone.
