Shock from iPhone 12 Pro Max
The phone has a protective case, but occasionally I've needed to take it off to swap a SIM card. When I do I get a sharp shock from the lower left edge of the phone. It feel like an electrical shock, numbing the tip of my finger.
Has anyone else felt this or heard of anything like this? Is it a design problem, or a manufacturing problem? If the latter I'll return it.
Thanks very much for any guidance.
