Apple Store gave me a new iPhone SE (3rd gen) 128GB Verizon, same as I had before. I'll let you all know if I still see the kernel panics.
Side note: I went through hell to get this replacement (direct from Apple) phone activated. Verizon Store and Verizon 1-800 customer service could not get the eSIM to work. Ultimately, I had to use a physical SIM. Keep that in mind if you are getting a replacement.
I’ve had the same problem with 2. First bought on launch day. Second about 2 weeks ago.
