I recently tried to repair my camera. Unfortunately, I damaged the flex cable that was attached to the back of the glass. I immediately stopped what I was doing, reconnected the battery, and camera cable, and put the phone back together without replacing anything. Now my phone reboots every so often when I am using it. Could this reboot be caused by the damaged flex cable?

Try to get a screenshot of the most recent kernel panic. If you go to Settings->Privacy & Security -> Analytics & Improvements -> Analytics Data, then scroll down until you find "panic-full". They are ordred by date and time. Find the most recent one and get a screen shot, it will give you info that will help you figure out what is causing the problem

This page has details about kernel panics: iPhone Kernel Panics
Thank you so much, I was able to find the problem. You are awesome! I also have a question, do you think aftermarket parts are just affective as the orginal apple products?
@jacqueline35004 What did the sensor array data contain? Is it indicating the wireless charging assembly? If so, according to my latest information, replacing that with an aftermarket part will result in, and I quote, "Function Loss (Parts Pairing or Calibration Issue)".

Starting with the iPhone 14, Apple has started pairing the wireless charging coil on the back glass to the motherboard, and generating what's called a kernel panic if it can't read the sensor embedded in the coil.
So yes, you can most definitely have a reboot being caused by that cable; in fact it's almost certain that's what the problem is. What's happening is that every three minutes the processor scans all the sensors in the phone. If it cannot read a particular sensor, a kernel panic is generated; that is, the operating system kernel logs the error then reboots the phone in an attempt to clear the error. Of course, if it's a hardware error like what yours appears to be, then in three minutes after it has rebooted when it goes to check the sensors again, it will find an error and go through the whole procedure again, and again, and again... to infinity and beyond. Unfortunately, the phone isn't quite smart enough to realize that if it's rebooted the phone 300 times, then reboot 301 is probably not going to help.
We're fortunate to have an actual former Apple service technician as a member here and they have written an excellent guide to understanding and interpreting kernel panics.
So what you'll want to do next is to read the wiki page, then use that information to locate and screenshot/cut'n'paste/download the latest panic log (we really only need the first page) and come on back and add that information to your question.

I'm fairly sure you'll find that your kernel panic is going to fall under the heading of an SMC Panic Assertion Failed error, which is documented on another Wiki page here.

Once we can see what your panic log says, we can help you determine what action to take next. Unfortunately, with Apple's increasing focus on making things non-repairable, you may lose functionality and/or get a bogus warning message whenever you restart your phone unless you take it to an authorized Apple repair center to get the issue fixed, but we'll know more once we can see the log.
