IPHONE 6 PLUS
I bought an Iphone 6 plus for my mother-off of marketplace. I am trying to update phone-so we can switch out her device. Everything works, except finger print security and when i tried to add the 360 app-it said that I needed to update: It says "This application requires ios 11.0 or later". When i go to software updates it says Checking for updates and just spins. Is the phone too old for update?
iPhone 6 Plus, iOS 9
