iPhone 4s touch screen not working, but Assistive touch does
I have an iPhone 4s with iOS 7.0.1. My phone's screen is cracked, but only slightly, and my home button is missing. It has been missing for about 2 weeks but it hasn't caused any problems because I have been using Assistive Touch.
Tonight, my phone's touch screen randomly stopped responding. The confusing part is that Assistive Touch still works, every single part of it, and I can still pull up the bottom iOS 7 menu with the change in brightness and everything on it, but other than that it does not respond at all.
After I pull up the iOS 7 menu, I cannot click anything on that menu and I cannot unlock it or anything else. I can't even slide to power down after holding the top button. With Assistive Touch, it does not allow me to hold down both the home and power button so I can't force it to shut down either. I do not currently have the computer to hook it up to my itunes account, so this is a real problem. Can anyone help?!
