things are done differently & you just have to learn the new system.
fwiw: i've gotten 2 of my wife's hand me down i-phones, 5s & 6+, which i only use on wi-fi.
i'm still using my 4 year old note5 & don't have any plans of changing to an i-phone any time soon.
It really just comes down to which system you prefer. For me, I believe iOS is a little more secure. Google tracks so much and collects a lot of data. I trust them less than I trust Apple. I would buy new Android phones every year until 2016 when I changed to Apple for my phones and tablets. I don't have any intentions of ever going back. Of course this is strictly my opinion and others will feel otherwise.
