My iphone was working fine on iOS 12, but updating it to iOS 12.0.1 has ruined it. The phone crashes randomly and now I can't connect to a wifi network. The wifi option will not turn on and is grayed out in the app tray. I've restarted, hard reset, rest network settings, and reset all my settings. I even resorted to restoring my phone to a previous back up. That worked for a few days, but today it's crashing again.
I spoke with someone with apple, and they don't know what's wrong. Told me to go in, but service wouldn't be available for 3 days!
