Trust me, android is fine with this. I left because of how slow my apple phone got after a forced upgrade that couldn't be undone. And pleases don't insult me by saying I wasn't forced.
You weren’t forced to. My iPhone 6 has remained on 9.3.2 and I don’t think I’ve missed anything. All of my apps work fine, and it is still buttery smooth. Nothing in iOS 10 and now nothing in iOS 11 is attractive enough for me to want to upgrade. It’s always possible something will come up, but right now I have a hard time thinking of what that might be.
