Panic Log Solutions

Summary
iPhones and iPads will restart randomly or every few minutes depending on various scenarios.

Also, each model tends to have it's unique sensors that must be detected by the Operating System, otherwise, it'll restart.

The first step to troubleshooting this issue is to start by testing the problematic board with all known good parts. Meaning, these are parts that have been previously tested & confirmed not to cause restart issues.

Next, would be to check the panic log to see which sensor is not detected. To find the panic log on the device, go to Settings-> Privacy-> Analytics & Improvements-> Analytics Data-> Scroll down to the files starting with "panic-full..." & click on the most recent dated file.
