Woman's phone flashes and then she has a vax siezure

What happens: She's just sitting there getting her nails done with her phone in her hand. She's not looking at it and has it down by her chest. At 12 seconds either an electrical pulse or the flashlight, which is pointed away flashes twice and she goes into a seizure. My guess is she's vaxxed and the phone triggered the seizure.

Cell phones in shirt pockets have for a long time been used to trigger heart attacks. Even in the brick phone days. The vax probably made it possible for the "controllers" to select what's going to happen to someone.

Someone sent a kill signal to her and murdered her. What happens when they send out this signal TO EVERYBODY?

What if it is the rake or zombie signal instead?
