I've noticed this as well just now.

Also experiencing this issue!

I'm seeing this too. But see how the Code Type is ARM-64? Since an iPhone 4 is a 32 bit system, it wouldn't have this CPU. ..Then when you dig into your log, it mentions iPhone13,1 which is an iPhone 12 mini. I've noticed the same in my logs - the details of the log show a different iphone version than the summary. In my case an iPhone 12 Pro was shown as "iPhone 4" So the issue is that Apple shows incorrect device information in the side panel. Thanks for letting me know I'm not the only user experiencing this!
