Panic CPU x Caller issue fixed?

Not really a question but I was doing some testing with the iPhone 7 Plus and it was having the Panic CPU x Caller issue so I thought it would be the front camera flex cable so, I was lazy and just swapped the screens to see if it’s the front camera flex cable could recreate the issue (which it did) and the original phone that has the problem started working with another front camera flex cable.

I’m not good at elaborating on what I did nor do I know if someone else figured this out before me but I need to find more people that has the similar issue for us to start testing if this theory of getting this error put to rest.
I talked to Apple about this but they wanted to charge me almost 300 as a “flat fee”

I’ll try to get a video up to show this in action
