I’ve had my Samsung S7 Edge for 3+ years - works absolutely perfect running Android 8 and functions as my primary work phone.
I’ve no interest in upgrading to a “new technology” phone when my current technology is working more than OK.
It still looks great with the curved edge screen and its high resolution.
And because iPhones are so good it creates a dilemma for Apple.
They make phones so good, that no one needs to buy a new one 2-3 years later.
Like Android people do.
