Your problems sending video only talk about your problems, not about what other people's problems.I don't have first hand experience of the Galaxy S6 but plenty of experience of Lollipop and when I tried to send a large video directly to another family member in the way that it is so easy on IOS I could not do it
On IOS families are busy using face time to keep in touch and sending video clips directly to each other because it is so easy a child can do it.
I know of people who have bought an iPad just in order to keep in touch with family members because it is so good and because it is so easy for their children to use.
Until Android can do that then people will ignore the superior specifications of flagship Android devices with their Widgets in favour of Apple.
You still try to state as a fact that iOS is easier to use than Android, but it is not true
