2 iPhone 7 Plus' Locking up
My wife and I both have an iPhone 7 Plus and both have the same issue. Ever since we updated to IOS 11.0 our phones will randomly lock up. We have to reboot the phones by holding down the lock button and the volume down button. Once it is rebooted, it performs as expected. We have both updated with each of the subsequent releases of iOS 11, but the issue still remains. This happens approximately once a day or every other day for the both of us.
2 identical phones, having the same issue, with the same starting point.
iPhone 7 Plus, iOS 11.1, iOS 11.1.1 (15B150)
