Unfortunately, this screen not responsive item cannot be fixed unless you have something really special like the apple diagnostic tools that they run when you bring it into the Apple Store.
when my phone went completely unresponsive, I felt like that movie “leave the world behind”, where I was basically rendered useless, because my phone could not function.
I didn’t have a back up phone, it just totally stopped working, and it made me contemplate getting a second phone just in case this ever happens again.
so much of our life is run on the mobile device that when all of our apps are not accessible, it kind of sucks how reliant we are on these devices and I don’t know if randomly my phones gonna stop working one day when I’m traveling or on the road and I’ll be left without a map or whatever.
if you’re on this thread, just go to the Apple Store and stop searching for a fix.
