yeah that's what I know, it is usually at one of the top corners, and being a massive phone, I'd probably struggle to reach that far up to go back
unless its a universal gesture where you swipe left to right to go back then that's alright
ecosystem as in the ease of use and transfer of data between devices no?
if you got a macbook, ipad or apple tv (box) then can transfer videos or notes or files between all these devices, then I guess it make sense la to get an iphone if the whole family is using it
