So I'm not the only poor parent trying to make due with a very old iPhone. My iPhone 6 died in a similar way, so I downgraded to an iPhone 5 which I had been using until it too died which may have had something to do with my son's tantrum and a smashed screen. So I was finally forced to upgrade, but only went as far as the iphone 12 mini. Let's see how long I can stay here before it also break!

Anyway, good luck moving forward!
