So I started out my smartphone life on android. (Well it was simian but it was so awful it doesn't even count) and lasted on android for around 3 to 4 years. Took the plunge and migrated over to iphone in 2013 on an iPhone 5c which sits in my drawer leading me to temptation! Anyway from 2013 to 2015 I had the iPhone. I left iphone coming back to android on a galaxy s6. It was my first samsung since my s2 and by far well made and superior in every way with build quality. Now comes 2017 with 9 or so months till upgrade time I'm heavily considering a return to the iOS world. I'm using ipad along with android so I know roughly what to expect with iOS. I am thinking of going sim only and perhaps adopting the iPhone upgrade program. You get the opportunity to upgrade each year.. does anyone know of any pitfalls of this program? or the exact positing of phone ownership and what happens if phone is damaged etc.
